The vertex of this parabola is at (-3, -1). when the y-value is 0, the x-value is 4. what is the coefficient of the squared expression in the parabola's equation?

Step-by-step explanation:

The vertex form of a quadratic equation is: y = a(x - h)² + k   where

Since the given information is (h, k) = (-3, -1)  and (x, y) = (4, 0), we can input those values into the vertex form and solve for "a":

0 = a[4 - (-3)]² + (-1)

0 = a(4 + 3)² - 1

0 = a(49) - 1

1 = 49a

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%
