The equation of the parabola whose focus is at (0, 5) and directrix at y = -5 is:
~ y = (1/20)x²
~ y = -(1/20)x²
~ x = (1/20)y²

ok i got it thx

Step-by-step explanation:

where are the choices?

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%
