Chapter 2.2, Problem 57PE

An athlete whose is the shot put releases the shot with the same initial velocity but at different angles. The figure shows the parabolic paths for shots released at angles of ${35}^{\circ }$ and ${65}^{\circ }$, Exercises 57-58 are based on the functions that model the parabolic paths.

when the shot whose path is shown by the blue graph is released at an angle of ${35}^{\circ }$, its height. F(x), in feet, can be modeled by

$f(x)=-0.01x^2+0.7x+6.1$

where x is the shot’s horizontal distance, in feet from its point of release. Use this model to solve parts (a) through (c) and verify yours answers using the blue graph.

a. What is the maximum height of the shot and how far from its point of release does this occur?

b. What is the shot’s maximum horizontal distance, to the nearest tenth of foot, or the distance of the throw?

c. From what height was the shot released?
