Solving Problems Involving Quadratic Relations
Solve the following problems involving quadratic relations. You can choose to do so algebraically or graphically. If you choose to solve it graphically, you must attach a rough sketch of the graph from Desmos. If you choose to solve algebraically, SHOW ALL OF YOUR WORK.
1.Two quarterbacks have a contest to see who can throw a football further. The first quarterback’s throw can be modelled by the equation . The second quarterback’s throw can be modelled by the equation h=−0.021 d^2+0.8 d+7, where h represents the height of the football in feet and d represents the horizontal distance in yardsa) Who threw the football further?b) Which throw reached a greater height?

On the volleyball court, one type of set on the ball can be modelled by the equation h=−5t^2+40t +7, where h is the height of the ball and t is the time in seconds after the ball is set.a) From what height is the ball set?b) How high was the ball after 2 seconds?c) What is the maximum height reached by the ball?
