Solve v^2=81 where v is a real number
simplify your answer as much as possible

v = 9 , − 9

Step-by-step explanation:

Take the root of both sides and solve.

if you're solving by the square root I think the answer would be 9 or -9 it's either one of those

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%
