You are trying to determine the height of a building whose base is on a level plane on which you stand. You are at the base of a vertical pole that you are able to climb. From
the base of the pole, you measure the angle to the top of the building to be 30°. You climb
a certain distance up the pole and measure again: the angle is now 28°. After climbing 10
feet further up the pole, you measure once more, and find the angle is 27º.
How tall is the building?

The polynomial function of least degree with a leading coefficient of 1 is: f(x) = x3 + ax2 + bx + c

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?
