An airplane 30,000 feet above the ground begins descending at the rate of 2000 feet per minute. a. Write an equation to represent the airplane's height above the ground in feet as a function of time in minutes.

b. How many minutes will it take for the plane to reach a height of 18,000 feet above the ground?

the answer is a

step-by-step explanation:

required rate of return = 0.166 = 16.6%

step-by-step explanation:

under the capital asset pricing model (capm), the required or expected rate of return for a particular security or asset is given using the formula:

required rate of return = risk-free rate + beta*(market risk premium)

we are given that;

risk-free rate = 4% = 0.04

beta = 1.4

market risk premium = 9% = 0.09

we simply plug these values into the above formula;

required rate of return = 0.04 + 1.4*(0.09)

required rate of return = 0.04 + 0.126

required rate of return = 0.166 = 16.6%
