The coordinates for 0 radians would be (5,0). The coordinates for /4 radians would be [(square root of 2)/2, (square root of 2)/2]. The coordinates for /2 radians would be (0,5). 5) Consider the two points in Quadrant I on Circle B. What is the special relationship between them?
(0.5 points) Create a budget. Save and invest money. 2. What is trade? (0.5 points) The exchange of things of value.
The first class in a relative frequency table is 50–59 and the corresponding relative frequency is 0.2. What does the 0.2 value indicate? Answer: ____Convert 0.2 to a % by times by 100. So 0.2 = 20%, so 20% of the data is between 50 and 59______________ 3. When you add the values 3, 5, 8, 12, and 20 and then divide by the number of values, the result is 9.6.
Variable costs include raw materials, energy/ power and labour cost. Total revenue is represented by an upward sloping straight line curve. Average cost Marginal cost is the additional to total cost when output is increased by one or more units. The MC controls the average total cost curve and cuts this curve at its lowest point. Marginal cost The games console market is an example of an oligopoly.
State in a few words, what is an exponential function? What is the natural exponential function? Evaluate 4–1.5 using a calculator. Round your answer to three decimal places. The formula S = C (1 + r)^t models inflation, where C = the value today r = the annual inflation rate S = the inflated value t years from now Use this formula to solve the following problem: If the inflation rate is 3%, how much will a house now worth $510,000 be worth in 5 years?
Discuss surplus-enhancing transactions in markets 6. Explain how elasticity affects the way in which the burden of a per-unit tax is shared between buyers and sellers 7. Explain how elasticity affects the size of the deadweight loss created by a per-unit tax **NOTE: All of chapter 5 of Hubbard, Garnett, Lewis and O’Brien (2011) Microeconomics, 2nd edition, Pearson is required reading. 1. Consumer surplus The difference between the highest price a consumer is willing to pay for a good or service, and the price they actually pay.
Chapter 6 8. 1. The parameters of the opportunity set are: E(rS) = 15%, E(rB) = 9%, sS = 32%, sB = 23%, r = 0.15, rf = 5.5% From the standard deviations and the correlation coefficient we generate the covariance matrix [note that Cov(rS, rB) = rsSsB]: Bonds Stocks Bonds 529.0 110.4 Stocks 110.4 1024.0 The minimum-variance portfolio proportions are: wMin(B) = 0.6858 The mean and standard deviation of the minimum variance portfolio are: E(rMin) = (0.3142 × 15%) + (0.6858 × 9%) = 10.89% = [(0.31422 × 1024) + (0.68582 × 529) + (2 × 0.3142 × 0.6858 × 110.4)]1/2 = 19.94% % in stocks % in bonds Exp. return Std dev. 00.00 100.00 9.00 23.00 20.00 80.00 10.20 20.37 31.42 68.58 10.89 19.94 Minimum variance
1 2 3 4 5 ROE 16.28% 13.21% 14.58% 16.28% 18.42% The IRR is an overall assessment of the project, so it is a fixed number. While the ROE is a periodical assessment of the performance of a company, so it is measured in all five periods. Besides, ROE is based on accrual earnings while the IRR is based on cash
