A builder makes staircases where each step is 28\,\text{cm}28cm28, start text, c, m, end text long and rises 18\,\text{cm}18cm18, start text, c, m, end text so people don't trip. Every staircase has a stringer — a diagonal support connecting all of the steps. A certain staircase will have 666 steps. What is the length \ellℓell of the stringer for this staircase? Round your answer to the nearest tenth of a centimeter. \text{cm}cmstart text, c, m, end text

Each step has a diagonal aka hypotenuse h that satisfies

h² = 28² + 18² = 1108

The total length of  666 diagonals is

l =666h =  666 √1108 ≈ 22168.898213488195

22168.9 cm

The length of the stringer ℓ is approximately 199.7m

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%
