determine whether each statement is true/false, and justify answer.
a) suppose that a is an invertible n\times n matrix with integer entries. if det(a) = 1 , then a^{-1} also has integer entries.
b) if a is a square matrix, then (adj(a)) = adj (a^t)

i think is g(1)=-1.

hope that i can

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%

i will with my problems and all the other things that need to   be on by the way
