The height of the football after 4 seconds is 80 feet
The height in feet of the punted football is a function of time the ball is in the air.
The function is represented as follows:
h(t) = -7t² + 48t
The height of the football after 4 seconds can be calculated as follows:
h(t) = -7t² + 48t
where
t = 4 seconds
Therefore,
h(4) = 7(4)² + 48(4)
h(4) = -7(16) + 192
h(4) = -112 + 192
h(4) = 80 feet

Answer:
The height of the football after 4 seconds is 80 feet.
Step-by-step explanation:
You know that the height (in feet) of punted football is a function of the time the ball is in the air and it is defined by:
h(t) = -7*t²+48*t
To calculate the height of the ball after 4 seconds, you must replace the time t by the time of 4 seconds:
h(4) = -7*4²+48*4
Solving, you get:
h(4) = -7*16+48*4
h(4) = -112+192
h(4)= 80
The height of the football after 4 seconds is 80 feet.
