Industrial Policy free essay sample
A discussion on the industrial policy in the U.S. and the effect of governmental involvement on its economy. This paper discusses the effect the industrial policy in the US has on its economy. The writer debates whether governmental involvement in the industrial policy is necessary and beneficial to the economy. The writer recognizes governments need to redirect resources to research and development of new technologies and regulate industries such as telecommunications and aviation. Industry in United States has always had a funny feeling about industrial policy, yet it has been in some of the most comprehensive growth industries in the market. The US is currently in the process of rolling back this policy, whose main target was specific sectors with regard to infrastructure, whether they are telecommunications or utilities. However, due to the explosion of the information age, the United States Government felt the need to redirect these resources, and the result, so far, has been Advanced Technology Program (ATP) under the direction and control of Institute of Standards and Technology (NIST). We will write a custom essay sample on Industrial Policy or any similar topic specifically for you Do Not WasteYour Time HIRE WRITER Only 13.90 / page And even though the program has had a great deal of success and has been most instrumental in the research and development of promising new technologies like fiber optics and fuel cell development, it is simply just another form of corporate welfare as described by Stephen Moore, Director of fiscal policy studies for the Cato institute.[i] However, there is good justification to still experiment with this kind of industrial policy because of the degree of success that they have had in the US as well as its limited success in Japan and Germany during the1980s and 90s.[ii] Even though the ATP is a good compromise between regulating the industry and letting the market be the complete master of macroeconomic policy, there has got to be better ways of achieving the same results without the degree of corporate welfare.

Its March. Do You Know What Time It Is Its March Madness, The NCAA Me
It's March. Do you know what time it is? It's March Madness, the NCAA Mens Basketball Tournament. The time of the year when you see commercials on CBS announcing the Road to the Final Four, the pinnacle of the college basketball year. Each year 64 teams vie for a spot in the Final Four. Teams from the East, Midwest, Southwest, and West all compete for one spot from each division. The teams that play for one of these spots can be classified into four different groups. The Number 1 through 4 seeds, the Cinderella teams, the Bubble teams and the One Hit Wonders. The Number 1 through 4 seeds make up 1/4 of the tournament. These teams are the strongest teams in the nation and are usually figured to go to the Final Four. The teams ranked Number 1 in their bracket have the best chance of going to the Final Four. Since 1980 at least one Number 1seed has gone to the Final Four. The number one seeded team has also never been beaten in the first round of the NCAA tournament. The teams that are 1 through 4 this year, and figure to be playing for the National Championship, are Kentucky, UMass, Purdue, Georgetown, Cincinnati, Utah, Villanova, and Arizona. All of these teams had to have had tremendous regular seasons and conference tournaments to be seeded so high. On the other hand a Cinderella team is a team that had a so-so regular season and upset a higher ranked team in their conference tournament. They ride that wave of momentum into the Field of 64 and hope to upset another higher ranked team in the first and second rounds. These teams usually don't last farther than the Sweet Sixteen where their season usually comes to an end. Teams that can be classified into this group are the 10 through 14 seeds. Teams that fall into this category are Clemson, Virginia Commonwealth, Austin Peay, Cansius, and Santa Clara. Out of these Cinderella teams, many of them were teams on the Bubble. These teams finished with a so-so regular season also but also had a so-so conference tournament. They had to sweat it out and hope for other teams to falter and the selection committee to be generous for these teams to make it. Once in the tournament these teams can be transformed into a Cinderella team by beating two higher seeded teams. Teams on the Bubble are ranked 7 through 9. The teams that can be classified into this category or groupings are Michigan, Stanford, Bradley, Wisconsin-Green Bay, and Eastern Michigan. That leaves the last grouping of teams. The One Hit Wonders. Their describes them perfectly. They usually upset one team then bow out of the tourney in the second round. The teams in this category might prematurely be labeled a Cinderella team, but after exiting the tournament in the second round they cannot be given this title. These teams can be ranked anywhere from 6 through 15. Teams from this group are Mississippi Valley, Louisville, Iowa, Indiana, Princeton, and Monmouth. So as one can see there are many different ways to view the teams from the Field of 64. From the Number 1's through Number 4's to the One-Hit Wonders there are many teams with a shot at winning the NCAA National Championship. You might ask, Which team do you feel will win the National Championship? I feel the National Championship will go to the Georgetown Hoyas ( a Number 2 seed ) out of the East.

Creating Your College Wish List
Creating Your College Wish List Figuring out where to apply to college is exciting, but it can be a major challenge. After all, there are over 3,000 four-year colleges in the United States, and each school has its own unique strengths and defining features. Fortunately, you can rather easily narrow down your search to a much more manageable number of colleges with the help of our series, Creating Your College Wish List. Youll find a variety of articles, sorted in easy-to-follow sectionsà that will guide you in the college selection process. Whether youre doing a national or regional search, whether you care most about engineering or the beach, or the most selective and prestigious colleges in the country, youll find articles here that feature top schools that speak to your interests. Every college applicant has different criteria for selecting schools, and the categories featured here capture some of the most common selection factors. The articles are organized to focus first onà topics that will be relevant to all college applicants, and later sections are more specialized. Read below to learn which sections will be most relevant to your own college search.à Tips for Narrowing Down Your College Listà The first step in coming up with your college wish list is to figure out what type of school you want to attend.à Understanding Different Kinds of Collegesà begins with an article that discusses 15 factors to consider when choosing a school. Along with the quality of the academics, you should consider a schools student / faculty ratio, financial aid resources, research opportunities, graduation rates, and more. Its also important to figure out if youll flourish at a small college or a large university. If youre a solid A student with strong SAT or ACT scores, be sure to look through the articles in the second section, The Most Selective Colleges.à Youll find a detailed list of the countrys most selective colleges and universitiesà as well as lists of the colleges that tend to top the national rankings. Whether youre looking for a top public university or one of the best liberal arts colleges, youll find information on a range of impressive schools.à Selectivity, of course, doesnt tell the whole story when choosing a college. Underà Best Schools by Major or Interest,à youll find articlesà focusedà on particular interests whether they be academic or co-curricular. Are you looking for a top engineering school? Or perhaps you want a college with a strong equestrian program. This third section can help guide your college search. Other colleges have a Distinct Student Body that might appeal to you. In the fourth section, youll find articles featuring schools with specialized missions including the top womens colleges and top historically black colleges and universities. The great majority of college students attend a school thats within a days drive from home. If youre restricting your search to a particular geographic region, youll find guidance in Best Colleges by Region.à Whether you want to learn about the top New England colleges or best schools on the West Coast, youll find an article identifying the top schools in your chosen area. If youre not a straight A student or your SAT or ACT scores are sub-par, dont worry. Inà Great Schools for Mere Mortals,à youll find top colleges for B students and a list of test-optional colleges that dont consider standardized test scores when making admissions decisions. A Final Word on Creating Your College List Keep in mind that words like top and best are highly subjective, and the best school for your particular strengths, interests, goals, and personality may very well be a college that isnt at the top of the national rankings. Once youre found the colleges that match your selection criteria, make sure your list includes a realistic mix of match, reach, and safety schools. Many of the schools featured here are highly selective, and plenty of students with strong grades and standardized test scores get rejected.à You should always shoot for the top, but make sure you have a contingency plan. You dont want to find yourself in the spring of senior year with no acceptance letters.

Algebraic Operations on ACT Math Strategies and Formulas
Algebraic Operations on ACT Math Strategies and Formulas SAT / ACT Prep Online Guides and Tips Variables, exponents, and more variables, whoo! ACT operations questions will involve all of these (and so much more!). So if you ever wondered what to do with or how to solve some of those extra long and clunky algebra problems (ââ¬Å"What is the equivalent to ${2/3}a^2b - (18b - 6c) +$ â⬠¦Ã¢â¬ you get the picture), then this is the guide for you. This will be your complete guide to ACT operations questions- what theyââ¬â¢ll look like on the test, how to perform operations with multiple variables and exponents, and what kinds of methods and strategies youââ¬â¢ll need to get them done as fast and as accurately as possible. You'll see these types of questions at least three times on any given ACT, so let's take a look. What Are Operations? There are four basic mathematical operations- adding, subtracting, multiplying, and dividing. The end goal for any particular algebra problem may be different, depending on the question, but the operations and the methods to solve them will be the same. For example, when solving a single variable equation or a system of equations, your ultimate objective is to solve for a missing variable. However, when solving an ACT operations problem, you must use your knowledge of mathematical operations to identify an equivalent expression (NOT solve for a missing variable). This means that the answer to these types of problems will always include a variable or multiple variables, since we are not actually finding the value of the variable. Letââ¬â¢s look at two examples, side-by-side. This is a single variable equation. Your objective is to find $x$. If $(9x-9)=-$, then $x=$? A. $-{92/9}$B. $-{20/9}$C. $-{/9}$D. $-{2/9}$E. $70/9$ This is an ACT operations problem. You must find an equivalent expression after performing a mathematical operation on a polynomial. The product $(2x^4y)(3x^5y^8)$ is equivalent to: F. $5x^9y^9$G. $6x^9y^8$H. $6x^9y^9$J. $5x^{20}y^8$K. $6x^{20}y^8$ (We will go through exactly how to solve this problem shortly) Let's break down each component of an operations problem, step-by-step. (Also, bonus French braid lesson!) Operation Question How-To's Let us look at how to identify operations questions when you see them and how to solve for your answer. How to Identify an Operations Problem As we said before, the end goal of an operations problem is not to solve for a missing variable. Because of this, you can identify an operations problem by looking at your answer choices. If the question involves variables (instead of integers) in the given equation and in the answer choices, then it is likely you are dealing with an operations problem. This means that if the problem asks you to identify an ââ¬Å"equivalentâ⬠expression or the ââ¬Å"simplified formâ⬠of an expression, then it is highly likely that you are dealing with an operations problem. How to Solve an Operations Problem In order to solve these types of questions, you have two options: you can either solve your problems by using algebra, or by using the strategy of plugging in numbers. Letââ¬â¢s begin by looking at how algebraic operations work. First, you must understand how to add, multiply, subtract, and divide terms with variables and exponents. (Before we go through how to do this, be sure to brush up on your understanding of exponents and integers.) So let us look at the rules of how to manipulate terms with variables and exponents. Addition and Subtraction When adding or subtracting terms with variables (and/or exponents), you can only add or subtract terms that have the exact same variable. This rule includes variables with exponents- only terms with variables raised to the same power may be added together (or subtracted). For example, $x$ and $x^2$ CANNOT be combined into one term (i.e. $2x^2$ or $x^3$). It can only be written as $x + x^2$. To add terms with variables and/or exponents, simply add the numbers before the variable (the coefficients) just as you would add any numbers without variables, and keep the variables intact. (Note: if there is no coefficient in front of the variable, it is worth 1. $x$ is the same thing as $1x$.) Again, if one term has an additional variable or is raised to a different power, the two terms cannot be added together. Yes: $x + 4x = 5x$ $10xy - 2xy = 8xy$ No: $6x + 5y$ $xy - 2x - y$ $x + x^2 + x^3$ These expressions all have terms with different variables (or variables to different powers) and so CANNOT be combined into one term. How they are written above is as simplified as they can ever get. Multiplication and Division When multiplying terms with variables, you may multiply any variable term with another. The variables do not have to match in order for you to multiply the terms- the variables instead are combined, or taken to an additional exponent if the variables are the same, after multiplying. (For more on multiplying numbers with exponents, check out the section on exponents in our guide to advanced integers) $x * y = xy$ $ab * c = abc$ $z * z = z^2$ The variables in front of the terms (the coefficients) are also multiplied with one another as usual. This new coefficient will then be attached to the combined variables. $2x * 3y = 6xy$ $3ab * c = 3abc$ Just as when we multiplying variable terms, we must take each component separately when we divide them. This means that the coefficients will be reduced/divided with regard to one another (just as with regular division), as will the variables. (Note: again, if your variables involve exponents, now might be a good time to brush up on your rules of dividing with exponents.) $${8xy}/{2x} = 4y$$ $${5a^2b^3}/{15a^2b^2} = b/3$$ $${30y + 45}/5 = 6y + 9$$ When working on operations problems, first take each component separately, before you put them together. Typical Operation Questions Though there are several ways an operations question may be presented to you on the ACT, the principles behind each problem are essentially the same- you must manipulate terms with variables by performing one (or more) of the four mathematical operations on them. Most of the operations problems youââ¬â¢ll see on the ACT will ask you to perform a mathematical operation (subtraction, addition, multiplication, or division) on a term or expression with variables and then ask you to identify the ââ¬Å"equivalentâ⬠expression in the answer choices. More rarely, the question may ask you to manipulate an expression in order to present your equation ââ¬Å"in terms ofâ⬠another variable (e.g. ââ¬Å"which of the following expressions shows the equation in terms of $x$?â⬠). Now letââ¬â¢s look at the different kinds of operations problems in action. The product $(2x^4y)(3x^5y^8)$ is equivalent to: F. $5x^9y^9$G. $6x^9y^8$H. $6x^9y^9$J. $5x^{20}y^8$K. $6x^{20}y^8$ Here, we have our problem from earlier, but now we know how to go about solving it using algebra. We also have a second method for solving the question (for those of you are uninterested in or unwilling to use algebra), and that is to use the strategy of plugging in numbers. Weââ¬â¢ll look at each method in turn. Solving Method 1: Algebra operations Knowing what we know about algebraic operations, we can multiply our terms. First, we must multiply our coefficients: $2 * 3 = 6$ This will be the coefficient in front of our new term, so we can eliminate answer choices F and J. Next, let us multiply our individual variables. $x^4 * x^5$ $x^[4 + 5]$ $x^9$ And, finally, our last variable. $y * y^8$ $y^[1 + 8]$ $y^9$ Now, combine each piece of our term to find our final answer: $6{x^9}y^9$ Our final answer is H, $6{x^9}y^9$ Solving Method 2: Plugging in our own numbers Alternatively, we can find our answer by plugging in our own numbers (remember- any time the question uses variables, we can plug in our own numbers). Let us say that $x = 2$ and $y = 3$ (Why those numbers? Why not! Any numbers will do- except for 1 or 0, which is explained in our PIN guide- but since we are working with exponents, smaller numbers will give us more manageable results.) So let us look at our first term and convert it into an integer using the numbers we selected to replace our variables. $2{x^4}y$ $2(2^4)(3)$ $2(16)(3)$ $96$ Now, let us do the same to our second term. $3{x^5}{y^8}$ $3(2^5)(3^8)$ $3(32)(6,561)$ $629,856$ And finally, we must multiply our terms together. $(2{x^4}y)(3{x^5}{y^8})$ $(96)(629,856)$ $60,466,176$ Now, we need to find the answer in our answer choices that matches our result. We must plug in our same values for $x$ and $y$ as we did here and then see which answer choice gives us the same result. If you are familiar with the process of using PIN, you know that our best option is usually to start with the middle answer choice. So let us test answer choice H to start. $6{x^9}y^9$ $6(2^9)(3^9)$ $6(512)(19,683)$ $60,466,176$ Success! We have found our correct answer on the first try! (Note: if our first option had not worked, we would have seen whether it was too low or too high and then picked our next answer choice to try, accordingly.) Our final answer is again H, $6{x^9}y^9$ Now let us look at our second type of problem. For all real numbers $b$ and $c$ such that the product of $c$ and 3 is $b$, which of the following expressions represents the sum of $c$ and 3 in terms of $b$? A. $b+3$B. $3b+3$C. $3(b+3)$D. ${b+3}/3$E. $b/3+3$ This question requires us to translate the problem first into an equation. Then, we must manipulate that equation until we have isolated a different variable than the original. Again, we have two methods with which to solve this question: algebra or PIN. Let us look at both. Solving Method 1: Algebra First, let us begin by translating our equation into an algebraic one. We are told that the product of $c$ and 3 is equal to $b$. A ââ¬Å"productâ⬠means we must multiply $c$ and 3 and so our equation looks like this: $3c = b$ Now we are asked to find the sum of $c$ and 3. This means we must isolate $c$ so that we can add them together. So let us first isolate $c$ by using our knowledge of algebraic operations. $3c = b$ $c = b/3$ Now, we can sum $c$ and 3 by replacing our $c$ with $b/3$. $c + 3$ ${b/3} + 3$ Our answer matches answer choice E. Our final answer is E. Solving Method 2: Plugging in numbers Alternatively, we can use our technique of plugging in numbers. Because our question deals with variables, we can choose our own numbers (so long as they follow the rules of our given information.) We are told that the product of $c$ and 3 is equal to $b$. So let us assign a value to $c$ and use this information to find the value of $b$. So let us say that $c = 4$. (Why 4? Why not!) If $c = 4$, then the product of $c$ and 3 is: $3c = b$ $3(4) = b$ $b = 12$ So, when $c$ equals 4, $b$ equals 12. Now we must find the sum of $c$ and 3. $3 + c$ $3 + (4)$ $7$ Now that we have found our sum, we must identify the answer choice that gives us this sum. All of our answer choices are presented to us in terms of $b$, so we will use our found value of 12 to replace $b$ for each. As with all PIN questions, let us start with the middle answer option. Answer choice C gives us: $3(b + 3)$ We can tell just by looking at it that this will be far larger than 7, but we can always test this out. $3(12 + 3)$ $3(15)$ $45$ We can eliminate answer choice C. Just by glancing, we can see that answer choices A and B will also be larger than 12, which means we can eliminate them as well. Let us try answer choice D. ${b + 3}/3$ ${12 + 3}/3$ $15/3$ $5$ Answer choice D did not match our sum, which means we can eliminate it as well. By process of elimination, we are left with answer choice E, but let us test it to be sure. ${b/3} + 3$ ${12/3} + 3$ $4 + 3$ $7$ Success! We have found the answer choice that matches the sum we found. Our final answer is, once again, E, ${b/3} + 3$. As you can see, the answer to your operations questions will always be in variables and the problem will always require you to interpret and manipulate expressions with variables, but there are always multiple options for how to solve these types of problems. You've got the power to decide how you would like to solve and manipulate your operations problems. Magic! Strategies for Solving Operations Questions Now that weââ¬â¢ve seen the types of operations questions youââ¬â¢ll see on the ACT, letââ¬â¢s review our solving strategies. #1: Use PIN when needed (or to double-check your answer) If you ever feel concerned that you may be going down the wrong path while manipulating your operations problems, or if you simply want to double-check your answer, it's never a bad idea to use the strategy of plugging in numbers. Although it can take a little longer plug in your own numbers for your variables, you'll never have to fear misremembering how to manipulate your exponents, your variables, or your equations as a whole. Once you're able to use real numbers for your variables, the math will be a piece of cake. #2: Focus on one aspect of the term at a time It can become all too easy to lose yourself when working with multiple variables at once, especially when it comes to multiplication and division. The test-makers know this and will provide bait answers for any number of common mistakes. In order to keep all your components organized, focus on just one piece of each expression at a time. First, look at the coefficients, then look at the variables. This will help keep all your moving pieces in order and lessen the odds of mix-ups and mistakes. #3: Eliminate your answer options as you go Operations problems can sometimes mess with your head, not because they are inherently difficult, but because the ACT is a marathon and your brain can get tired and confused (and lazy). This, combined with the fact that all the answer choices generally look quite similar, with only small differences- a minus sign instead of a plus sign, one coefficient difference, etc.- can lead you to select the wrong answer, even when you know what the correct one should be. To avoid this kind of careless error (the worst kind of error!), eliminate your answer choices as you go through your problem. Know that the coefficient for your $y$ value must be 3? Immediately cross out any answer choices that give you anything other than $3y$. It may seem inefficient to solve problems this way, but it will keep your answers much more clear. #4: Keep careful track of your negatives Not only can it be difficult to keep track of multiple variables, but it's even easier to mix-up the proper negative and positive signs. Many students make careless errors with their negative signs and the ACT test-makers are all too aware of this. They will provide all manner of bait answers for anyone who misplaces even a single negative sign, so be very careful. $(a+2b+3c)-(4a+6b-5c)$ is equivalent to: A. $-4a-8b-2c$B. $-4a-4b+8c$C. $-3a+8b-2c$D. $-3a-4b-2c$E. $-3a-4b+8c$ For a problem like this, we are being asked to subtract the entire expression, $4a + 6b - 5c$, from the entire expression, $a + 2b + 3c$. This means that the negative sign will be negating every term in the expression $4a + 6b - 5c$. So we must put a negative sign in front of each term. $4a$ becomes $-4a$ $6b$ becomes $-6b$ $-5c$ becomes $- -5c$ or $+5c$. Now let us put these pieces together with the first expression. $a - 4a = -3a$ $2b - 6b = -4b$ $3c + 5c = 8c$ Our final expression will be: $-3a - 4b + 8c$ Our final answer is E, $-3a - 4b + 8c$. [Note: many (many!) students put a negative sign only in front of the first term in the parenthesis, which in this case the $4a$. If you had done this, you would have gotten: $a - 4a = -3a$ $2b + 6b = 8b$ $3c - 5c = -2c$. This would have given you answer choice C, $-3a + 8b - 2c$. Again the test-makers know this is a common error and there will always be a bait answer to tempt anyone who makes this kind of mistake.] Operations in the "real world." Hyuk, yuk, yuk. Test Your Knowledge Now that weââ¬â¢ve gone through the tips and tricks of operations questions, itââ¬â¢s time to put your knowledge to the test with more real ACT math problems. 1. Which of the following is an equivalent simplified expression for $2(4x+7)-3(2x-4)$? F. $x+2$G. $2x + 2$H. $2x+26$J. $3x+10$K. $3x+$ 2.Which of the following expressions is equivalent to ${1/2}y^2(6x+2y+12x-2y)$? A. $9xy^2$B. $18xy$C. $3xy^2 + 12x$D. $9xy^2-2y^3$E. $3xy^2+12x-y^3-2y$ 3.$t^2-59t+54-82t^2+60t$ is equivalent to: F. $-26t^2$G. $-26t^6$H. $-81t^4+t^2+54$J. $-81t^2+t+54$K. $-82t^2+t+54$ 4.The expression $-8x^3(7x^6-3x^5)$ is equivalent to: A. $-56x^9+24x^8$B. $-56x^9-24x^8$C. $-56x^18+24x^15$D. $-56^18-24x^15$E. $-32x^4$ Answers: H, A, J, A Answer Explanations: 1. As always, we can solve this question using algebra or using PIN. Let us look at both ways. Method 1: Algebra First, we must distribute out our terms. Only afterwards will we subtract them. Let us take each half of our expression by itself. $2(4x + 7)$ $8x + 14$ $ -3(2x - 4)$ $-6x + 12$ (Note: keep careful track of your negatives here, especially in the second half of our expression.) Now, we can put the two together. $8x + 14 - 6x + 12$ $2x + 26$ We cannot go any further, as we have combined all our like terms. Our final answer is H, $2x + 26$ Method 2: PIN As an alternative to algebra, we can always use plugging in numbers. So let us assign our own value to $x$, which we will call 3. (Why 3? Why not!) This means that we will replace any $x$ in our given equation with a 3. $2(4x + 7) - 3(2x - 4)$ $2(4(3) + 7) - 3(2(3) - 4)$ $2(12 + 7) - 3(6 - 4)$ $2(19) - 3(2)$ $38 - 6$ $32$ Now, let us find the answer choice that matches with our found answer of 32, once we replace the $x$ with 3. As usual, when using PIN, let us start with the middle answer option. $2x + 26$ $2(3) +26$ $6 + 26$ $32$ Success! We found our answer on the first try. But remember- when using PIN, always check your other answer options to make sure there are not repeat correct answers. We can see straightaway that answer choices F and G will be too small, since answer choice H was a match. So let us try answer choice J. $3x + 10$ $3(3) + 10$ $9 + 10$ $19$ This answer choice is too small and we can see just by looking that answer choice K will be too small as well (since they only differ by 1). This means we are safe with our answer choice H, as no others produced a match. Our final answer is H, $2x + 26$. As we saw from earlier in the guide and from the example problem above, we can always use algebra or PIN for our operations problems. Knowing that, we will only go through one method each for the rest of our answer explanations. 2: For this problem, let us do our solve using algebra (again, we could also use PIN, but for the sake of brevity, we are only choosing one method for each problem). We are given the equation: ${1/2}y^2(6x + 2y + 12x - 2y)$ Now, let us first make life easier by combining the like terms in the parenthesis. $(6x + 2y + 12x - 2y)$ $(6x + 12x + 2y - 2y)$ $(18x)$ The $y$ terms cancel one another out, so we are left with only $18x$ in the parenthesis. Now, we must multiply our $18x$ by ${1/2}y^2$. As always, when multiplying, we must multiply first the coefficients and then combine them with the combined variables. So: ${1/2}y^2 * 18x$ $(1/2) * 18 = 9$ $y^2 * x = y^2x$ Put the two together and we have: $9y^2x$ So our final answer is A, $9xy^2$ 3: Because we used algebra last time, let us try our hand at solving this question using PIN. Because we are using our own numbers, we donââ¬â¢t have to worry about whether or not we are matching up the right terms, or if we are combining them incorrectly; we can bypass all the mess and use numbers instead. We have one variable, $t$, so let us say that $t = 2$. (Why 2? As always, why not!) $t^2 - 59t + 54 - 82t^2 + 60t$ $(2)^2 - 59(2) + 54 - 82(2)^2 + 60(t)$ $4 - 8 + 54 - 328 + 120$ $-268$ Now, we must find the answer choice that matches our found answer of 102, once we replace $t$ with 2. Let us start in the middle, with answer choice H. $-81t^4 + t^2 + 54$ $-81(2)^4 + (2)^2 + 54$ $-81(16) + 4 + 54$ $-1296 + 58$ $-1238$ We can see just by looking that answer choice G will be too small as well ($-26 * 16 = -416$), and answer choice F will be too large (-26 * 4 = -104). So let us try answer choice J. $-81t^2 + t + 54$ $-81(2)^2 + 2 + 54$ $-81(4) + 56$ $-324 + 56$ $-268$ Success! And we can also see that the only difference between answer choices J and K are the coefficient in front of $t^2$ (-81 vs. -82), so we know that answer K would produce an incorrect and smaller number than answer choice J. Our final answer is J, $-81t^2 + t + 54$ 4: Because we used PIN last time, let us use algebra for this problem. Because we do not have like terms in the parenthesis, we must distribute out our expression using multiplication. $-8x^3(7x^6 - 3x^5)$ $-8x^3(7x^6) - -8x^3(3x^5)$ And take each piece separately. $-8x^3(7x^6)$ = $-8 * 7 = -56$ and $x^3 * x^6 = x^[3 + 6] = x^9$ (for more on this, look to the section on exponents in our advanced integers guide). So, combined, we have: $-56x^9$ And the other half of our expression will be the same. $- -8x^3(3x^5)$ $8x^3(3x^5)$ = $8 * 3 = 24$ and $x^3 * x^5 = x^[3 + 5] = x^8$ So, combined, we have: $24x^8$ Now our equation looks like this: $-56x^9 + 24x^8$ Our final answer is A, $-56x^9 + 24x^8$ (Take care! The only difference between answer choice A and B is the negative sign. If you werenââ¬â¢t careful with your double negatives, you may have fallen for this bait answer.)

Analyse the business environment of Japan Essay
Analyse the business environment of Japan - Essay Example In order to drive this growth, National Innovation System (NIS) plays a very important role. Innovation is one of the key drives that have led Japanese business corporations to this state of success. This paper presents a detailed study of the activities of NIS which helps to evaluate its impact on the business environment of the country. Business environment in Japan The Japanese business environment has been reflecting huge success during the late 1980s. The success of Japanese business enterprises is affected by the formation of the enterprise to a large extent. Three main types of companies can be recognized in Japan under Japanââ¬â¢s commercial code and another form of company is separately recognized under the Yugen Gaisha Law. Therefore, four different forms of a business company exist in Japan. These are Go-mei Gaisha (or commercial partnership), Go-shi Gaisha (or limited partnership), Kabushiki Kaisha (or general corporation) and finally Yugen Gaisha (or limited liability corporation) (Japanlaw, n.d.). ... Cheap exports made by Japan include particularly electronic devices, cars and computers (Japan-guide, 2013). This characteristic of Japanese business corporations is imparted by the human resource of these organizations. Human resource is considered a very important aspect in Japan. Hence, companies dedicate attention towards maintaining good human resource management system and employees provide the commitment of sustaining a long-term relationship with their respective corporations. Strong industrial relationship is one of the main factors that affect the performance of Japanese business firms in international context (Asetuc, 2003). This leads to improvement in the skills and employees might utilize their potential to the fullest extent for the growth of their organization. With globalization, Japan has been increasingly participating in the global business scenario. Japan is known on the global platform for its cheap exports. Japan mainly imports agricultural or intermediate good s, such as, culinary materials, wood, oil and other raw materials. Since the manufactured goods (imported) yield higher price than the raw materials imported by Japan (that requires lesser payments), Japan has a trade surplus. However, globalization makes the manufacturing units all around the world more cost efficient (Gu?jonsson, 2009). Thus, Japanese firms are currently facing intense competition in the global front. National Innovation System (NIS) Government component of the NIS The National Innovation System (or NIS) refers to the system of flow of information as well as the rapid transfer of technological knowhow amongst people residing in different parts of a country. It has been recognized by the Japanese government

The Exercise of Accounting Clothes Personal Statement - 2
The Exercise of Accounting Clothes - Personal Statement Example I thought that I had only few purchases that were made from China but I did not expect that majority of them were actually from China (there were 22 clothes that I bought coming from them). This misimpression is due to the fact that even if the brand is patently American, if we bother enough to check the label on where it is made, it is in fact made in China. For example, my sport apparel Nike. We know that Nike is an American company and we would like to think that it is also made in America. But no, check the labels and you cannot even read them because it is written in Chinese character. It is in fact made in China. This led me to think and do some basic research. I begun to understand the supply chain that companies employ in order to save cost and become competitive. But again, this led me to think if the main motivation really is to save on cost to sell their products more affordable then are their prices are saying otherwise? Nike is still priced at premium even if they had ou tsourced their manufacturing to some sweatshops in China. These companies are raking billions of dollars in profit. The motivation of having their manufacturing somewhere else must be the drive to profit more by finding ways to cut cost by looking for people who can do the job the cheapest way possible. Sadly, this takes jobs away from Americans and kills our local garment industry. This also makes the salary of those who works in our textile industry low because of competition of the dirt cheap salary of textile workers in Bangladesh and Cambodia. Worst, this outsourcing has brought new evils in the country that they were outsourced such as China and countries in South East Asia (Thailand, Indonesia, Philippines). News about the old labor, unreasonably long working hours and dangerous working conditions are prevalent that it defeats the benefit of giving people jobs because they are being exploited. Also, the quality of the textiles deteriorates because the manufacturing process of the countries they are from cut corners. Also, I noticed during the process of my accounting my clothes that some have labels of being recyclable (the ones made in USA) while many do not. I understood it because of our stringent laws about the environment and our general concern about the environment. I checked the labels on the other clothes that I have that were made overseas and there were no labels that the clothes can be recycled. This led me to think that these manufacturers must have no concern for the environment after making the sales or even during the manufacture of these clothes. Come to think of it, if they cared less about their workers, employing them in hazardous working conditions and giving them oppressive salaries whose ill effects can be immediately observed, how much more about the environment whose effect can only be felt many years ahead? Also, the quality of the fabric can readily be distinguished because those that came from the USA are noticeably of better quality. We just came from a financial crisis and to some extent, we are still reeling from it.

Moisturize your Face with Steam Essay Example for Free
Moisturize your Face with Steam Essay Steaming is one of the most effective methods of removing pimples. To apply this method, boil water in a container for a couple of minutes. After that, place the container containing boiled water beneath your face. Allow the steam to dampen your face for a couple of minutes. Afterwards clean your face with lukewarm water. Boiling water helps remove debris and oil from your face without increasing the pimples. Alternately, you can use an oil free lotion to moisturize your face and remove pimples. Apply Toothpaste on your Pimples This is the most common cure for pimples. Of course, you may brush your teeth before sleeping every night, but this time, apply toothpaste on your face! Ideally, wake up once or twice in the night to ensure that the paste still covers the spot. You can apply the paste again if that is not the case; doing so will clear up your face in the morning. However, use toothpaste only and never apply gel on your pimples. Apply Lavender Oil on the Acne This is a less common remedy for pimple growth but it is known for bringing results, especially on teenagers. Apply lavender oil on your pimples several times and before going to sleep. This oil helps to dry up the spots to a great degree. Use Lemon Juice Another effective method of curing acne is applying lemon juice. When you rub lemon juice on your pimples, it has a quick effect. Use it before going to sleep to see great results in the morning. 9 ways to prevent a breakout and get clear skin 1. Do the One-Minute Rule Using a face wash laced with salicylic acid (from one to two percent depending on how bad, and how often, you break out) is a surefire way to stop pimples from forming. Its simple: Instead of spot treating after one pops up, youre keeping every single pore clear from the get go. Suds up in the morning and night, and then wait one full minute before rinsing so the gentle exfoliator can work its pore-clearing magic. 2. Wipe Away Oil If your T-zone typically resembles an oil slick 24/7-or youve worked up a sweat crossing off your to do list-dont wait until you get home to degrease. When excess sebum (aka oil) seeps into your pores, pimple-promoting bacteria will quickly follow. Use a pre-moistened salicylic acid-soaked cleansing cloth directly on oil-prone zones (i.e. your forehead, nose, chin) to help keep skin clean and prevent future breakouts. 3. Dont Forget to Hydrate Just because acne-prone skin has plenty of oil to go around, doesnt mean its water content, which is crucial for healthy skin, is up to par. Plus, overuse of oil-fighting products can leave skin parched-and wanting to compensate with more oil (eek!). Look for a lightweight, oil-free face cream that gives just the right amount of hydration, but wont contribute to your acne issue. What you want: A formula that contains hydrators that mimic those in skin naturally, like ceramides, humectants, and squalene. If your skin is super prone to acne, opt for an even lighter gel, not cream, texture. 4. Turn up the TLC Sometimes even if your skin is having a good (aka clear) day, you can still see some redness. Thats because acne is essentially inflammation, so some irritation all the time or post-pimple is common. Soothe sensitive skin overnight with calming botanicals such as chamomile, licorice, or aloe vera extract. 5. Exfoliate on the Regular Once or twice a week, take your skin smoothing up a notch and use a product that contains salicylic acid (or look for willow bark extract, its all natural counterpart) along with gentle fruit enzymes. This powerful pore-perfecting combo will help rev cell turnover and prevent dead skin cells, debris, and bacteria from building up in pores. 6. Start Using Retinol The gold standard of anti-aging also has an amazing anti-pimple track record. Apply a thin coat of a retinol-based treatment all over skin (if youve never used it before, you may need to work up to nightly; start off with three days a week to see how skin holds up to its potentially irritating effect). This vitamin-A derivative amps up cell turnover like no other so that pores have no choice but to stay clear. 7. Go Hands Free As in: Stop. Touching. Your. Face. Stress and hormones gone haywire are common culprits of a breakout-prone complexion but are not the only instigators. Piling on dirt all day long, like from constant contact with your iPhone or fingers, can create the perfect breeding ground for bacteria. Wipe down your cell phone once a day with an alcohol wipe or squirt some hand sanitizer on a tissue and rub it on the surface. And as you talk on your device, try not to press it firmly into your skin-it will only push makeup and dirt further into pores, causing you more pimple problems. 8. Feed Your Face Diet has a huge impact on skin and skin health (including acne): Up to 80 percent of your skin is affected by what you eat and drink. Fill your plate with a healthy, well-balanced diet to keep skin in the clear. Focus on eating plenty of fresh fruit and vegetables that are rich in vitamin A (grapefruit, mango, broccoli, and kale) to help normalize the production of dead skin cells, a key factor in acne breakouts. And add in eggs, salmon, and walnuts, which contain healthy oils that keep your complexion well nourished and help prevent pimples. 9. Chill Out Because the more you stress over a zit the bigger its going to get. When the stress hormone cortisol spikes, so does oil production-one of the main causes of adult acne (along with hyperactive lifestyles, alcohol, poor diet, and too much cumulative sun exposure). Instead, spot treat the bad boy with bacteria-fighting benzoyl peroxide. Natural Ingredients to Get Rid Of Acne Scars Fast Acne does not only scar the skin but also the mind and emotions of an individual. Walking down the road with a red swollen face filled with pus is a very embarrassing and painful both literally and figuratively. There are people who canââ¬â¢t help themselves talk about the other person who has a scarred face as a result of widespread acne. These reasons make people with acne find the quickest way to get rid of acne scars. They want to start a normal life without pain. They want to regain their confidence and self-esteem. There are the natural ingredients present in your kitchen. However, if you feel like the type of acne scars that you have are alarming, it is still best to consult a specialist about it. Here are some of the natural ingredients that can be very beneficial to quickly get rid of acne scars. Egg whites are rich in protein. Protein is very helpful in repairing ripped muscles and skin. These egg whites, about three pieces must be beaten into a fluffy and foamy texture. It must then be smothered on the face and act as a face mask. After a few minutes, this egg white mask must be rinsed with warm water. This method can be done 2-3 times in a week. Aloe Vera juice can also be a great natural remedy. We can see a lot of skin care products that contain Aloe Vera in its ingredients. Aloe Vera is an immune system booster. It also regenerates damaged skin tissues. Another natural ingredient that is commonly found in skin care products is lemon juice. Lemon contains AHA. AHA can thicken the skin and enables it to produce collagen. As this occurs, healing of the scarred skin is also sped up. Lemon juice has acidic elements. This acid helps in drying the acne quickly before it gets worse. A pinch of baking soda mixed with water can also remove the dead skin without hurting the skin. This mixture must be massaged gently on the skin. It can stay on the skin for a few minutes, then, it must be rinsed. Ginger is a natural antibacterial. A slice of it can be smeared on the infected area. After a few minutes, the face needs to be rinsed. This could be more painful than the other ingredients above mentioned because of ginger is a little bit spicy. These are just some of the many natural ingredients that can help you to quickly get rid of acne scars as they dry, peel and heal the scars. These methods will not be of great help if they will be done on a dirty face. After a long day of being exposed to pollution, our pores are clogged with dirt. The face must be very clean before any ingredient is placed on it or it will result to further damages and infection on the skin. So, for people who donââ¬â¢t know how to get rid of acne scars fast, these are some useful tips. Also, keeping the body hydrated is very important. Drinking the right amount of water is very useful in draining toxins that are present in the body because of the food that we eat.
