Concept explainers
A quarterback tosses a football to a receiver 40 yards downfield. The formula
models the footballs height y, in feet, when it is x yards from the quarterback.
a. How many yards from the quarterback does the football reach its greatest height? What is that height?
b. Ifa defender is 38 yards from the quarterback, how far must he reach to deflect or catch the ball?
c. If the football is neither deflected by the defender nor caught by the receiver, how many yards will it go, to the nearest tenth of a yard, before hitting the ground?
d. Graph the equation that models the footballs parabolic path.

To find the length of the bridge, he makes a right triangle with one leg and the hypotenuse on land and the bridge as the other leg. The length of the hypotenuse is 340 feet and the leg is 160 feet. Find the length of the bridge.arrow_forward
