Solve for z

Z - 4/9 - 1/3 = 5/9

4/3

Step-by-step explanation:

Z-4/9-1/3=5/9

Z-7/9=5/9

Z=5/9+7/9

Z=4/3 not sure

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%

thus, the first answer choice, y = sec x, is the correct one
