Point R(−3, 9) belongs to the graph of the function y= k/x^2 . Find the value of k.

k = 81

Step-by-step explanation:

y = k / x²

Plug in values.

9 = k / (-3)²

9 = k / 9

Solve for k by multiplying both sides by 9.

k = 81

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%
