Step-by-step explanation:

Pythagoras formula for a triangle with a 90 degree angle :

a^2 + b^2 = c^2

c is the side opposite of the 90 degree angle. exactly or situation here.

=> 9^2 + 12^2 = x^2

=> 81 + 144 = x^2 = 225

=> x = sqrt(225) = 15

idk the answer i want to say 10 but then it would be equal so try 9 but then yeah so yeah we love edgen

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%
