The function C(F) =5/9 (F - 32) is used to convert temperature from Fahrenheit (F) to Celsius (C). The function K(C)= C + 273.15 is used to convert temperature from Celsius (C) to the Kelvin (K) scale. Write a function to convert 77°F to the Kelvin scale.

To express temperature in Kelvin as a function of Fahrenheit, compose the functions as(_*_)(_).

Now, derive the function described above and use it to express 77°F as ___K.

What is the solution to the inequality

Aschool typically sells 500 yearbooks each year for 50 dollars each. the economic calls does a project and discovers that they can sell 100 more yearbooks for every $5 decrease in price. the revenue for yearbook sales is equal to the number of yearbooks sold times the price of the yearbook. let x represent the number of $5 decrease in price. if the expression that represents the revenue is written in the form r(x)=(500+ax)(50-bx). to maximize profit, what price should the school charge for the yearbooks? what is the possible maximum revenue? if the school attains the maximum revenue, how many yearbooks will they sell?
