Cindy has 26 nickels. she is getting rolls of nickels from the bank. she has enough money to get up to 10 rolls of nickels and each roll contains 40 nickels. the bank will not give partial rolls. the function that models the number of nickels cindy will have after leaving the bank is f(r)=40r+26, where r is the number of rolls of nickels she gets. what is the practical domain of the function? all real numbers {66, 106, 146, 186, 226, 266, 306,  346, 386, 426} r> 1 all integers from 1 to 10, inclusive

We know that the domain is actually the number of rolls that she gets because it is the input variable in the equation  f (r) = 40 r + 26. The number of rolls that she can get can never be a negative number nor a zero nor a decimal number. However she can only get up to 10 rolls. Therefore the answer is:

all integers from 1 to 10, inclusive

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%

he kicked it up? is this the answer ?
