tan^2 x sec^2 x +2 sec^2 x - tan ^2 x= 2

on the interval

Step-by-step explanation:

The given equation is:

We rearrange to get:

Factor by grouping:

Apply the zero product principle:

When

Then

This implies that:

When , we get  , x is not defined for real values.

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%
