The orcs are cgarging toward Helm's Keep with ladders to climb up the famous 30-meter walls of the fortress. The orcs also know about the OSHA safety rule about having a 75 degree angle between the ladder & the ground.

part a.) how long should the ladder be to reach the top of the wall? round to the closest meter.

part b.) how far from the wall should the base of the ladder be for safe climbing?

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%

the graph line crosses the x axis at both -6 and -2, so the answer would be the second one.
