Line segment bd is a diameter of circle e.

what is the measure of arc bc ?

39°
78°
102°
129°

the correct answer is:

78°

explanation:

since bd is a diameter, the measure of arc dab is 180° .

the measure of an inscribed angle is half that of the intercepted arc. since ∠dbc = 51°, arc cd = 2(51) = 102°. this means together the two arcs are 180+102=282°.

this leaves 360-282=78° for arc bc.

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%
