Tina throws a baseball straight up from a height of 3 feet and at a speed of 50 feet per second. The height of the ball in feet
vodka [1.7K]

Answer:

9 feet

Step-by-step explanation:

The height of the ball in feet is given by the polynomial:

h(t) = -16t^2+50t+3

where t is the time in seconds.

After 3 seconds, t = 3:

h(3) = -16(3)^2 + 50(3) + 3 \\\\h = -144 + 150 + 3 = 9 feet

The height of the ball after 3 seconds is 9 feet.
