Use the formula to answer the questions. 3(1) = 700,000(o.8)t What is the rate of depreciation (in dollars per year) after 1 year? $ per year (Do not round until the nal answer. Then round to the nearest cent as needed.) What is the rate of depreciation (in dollars per year) after 10 years? $ per year (Do not round until the nal answer. Then round to the nearest cent as needed.) What is the rate of depreciation (in dollars per year) after 15 years? $ per year (Do not round until the nal answer. Then round to the nearest cent as needed.) Recently, a certain bank offered a 5-year CD that earns 2.2% compounded continuously. Use the given information to answer the questions. (a) If $10,000 is invested in this CD, how much will it be worth in 5 years? approximately $ (Round to the nearest cent.)

Use the price-demand equation to find E(p), the elasticity of demand. x=f(p)= 19025 In (p) 5(9) = \fThe demand x is the number of items that can be sold at a price of $pi For x = p3 - 3p + 900, find the rate of change of p with respect to x by differentiating implicitly. The rate of change of the price p with respect to the demand x is
