Concept explainers
A quarterback tosses a football to a receiver 40 yards downfield. The height of the football, f(x), in feet, can be modeled by
where x is the ball’s horizontal distance, in yards, from the quarterback.
a. What is the ball’s maximum height and how far from the quarterback does this occur?
b. From what height did the quarterback toss the football?
c. If the football is not blocked by a defensive player nor caught by the receiver, how far down the field will it go before hitting the ground? Round to the nearest tenth of a yard.
d. Graph the function that models the football’s parabolic path.

- The resistance of a copper wire carrying an electrical current is directly proportional to its length and inversely proportional to its cross-sectional area. A copper wire with a diameter of 0.0126inch has a resistance of 64.9ohms per thousand feet. What length of 0.0201-inch-diameter copper wire will produce a resistance of 33.5ohms?arrow_forwardAssume that an object tossed vertically upward reaches a height of h feet after t seconds, where h=100t16t2. What is that maximum height?arrow_forwardA Skydiver When a skydiver jumps from an airplane, his downward velocity, in feet per second, before he opens his parachute, is given by v=1761-0.834t, where t is the number of seconds that have elapsed since he jumped from the airplane. What is the velocity after 5 seconds?arrow_forward
