unknown leg length in right tringles

which equation can be used to find the unknown length, b, in this triangle?
5 in.
4^2*b^2=5^2
4^2-b^2=5^2
5^2+4^2=b^2
5^2+b^2=4^2

answer:

4² + b² = 5²

step-by-step explanation:

side lengths in right triangles can be calculated with pythagorean theorem.

a² + b² = c²

"c" is the hypotenuse, the longest side.

"a" and "b" are the other two sides, it does not matter which one is "a" or "b".

in this problem, you are missing "b", which is not the hypotenuse. use the formula.

4² + b² = 5²

the correct answer is x/3+10≥32

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%
