1) A ball is thrown from the top of a building and follows the path given by a h(d)=-0.05d^2+1.25d+36.1875

Where d is the distance on the ground in yards and h(d) is the height in yards

A) Does the call ever reach a height of 60 yards? If so what is the distance?

B) find the maximum height of the ball

C) find the distance the ball is thrown when it hits the ground

2) a company knows that -2p + 1500 models the number of wheelbarrows it sells per month, where p is the price of a wheelbarrow. Revenue from sales is the number of wheelbarrows multiplied by the price of the wheelbarrow.
