For y = 3x - 2x^2 + 5x^3, show how to find the value for y when x = 3. show your work.

When x = 3 just substitute in equation and solve

y = 3(3)- 2x^2 + 5x^3

Y= 9-2(3)^2+5(3)^3

Y = 9-18+135

Y= 126

no he doesnt because "-16' is negatiive

step-by-step explanation:

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%
