The slope of ab is 2/5 . a(3, k) is a point on the line ab. find k if b(-7, 0).

slope of any line with 2 points is,

m=(y2-y1)/(x2-x1)

In this case,

m=2/5

(x1,y1)=(3,k)

(x2,y2)=(-7,0)

So,

》2/5=(0-k)/(-7-3)

》2/5=-k/-10

》k=20/5

》k=4

this is not the answer this is just a question. is this middle school math?

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%
