Riders must be at least 48 inches tall to go on the roller coaster. li's little brother is 3 feet 6 inches tall. which inequality can be used to find how many inches he must grow to be able to ride the roller coaster

Minimum height to ride roller coaster is 48 inches

Litlle brother's height is 3 feet 6 inches = 3 x 12 inches + 6inches ( 1 foot = 12 inches)

- 36 + 6 inches = 42 inches

Little brother needs to grow 48 - 42 inches = 6 inches

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%
