Write y=-2x^2-20x-52 in vertex form then find the axis of symmetry. show your work!

Step-by-step explanation:

y = -2x^2 -20x -52

y = -2(x^2 +10x) - 52

y = -2(x^2 + 10x + 5^2) + 2(5^2)-52

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

axis of symmetry: x= -5

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%

step-by-step explanation:

the triangles are similar. therefore the corresponding sides are in proportion:

              cross multiply

            divide both sides by 32
