Question

A volleyball is served by a 6-foot player at an initial upward velocity of 33 feet per second. The situation is modeled by the equation h = -16t^2 + 33t + 6 h representing the height in feet and t representing the
time in seconds. Using this equation, define the domain of the ball when it reaches its maximum height. (1 point)

-1.03 seconds

1.22 seconds

1.03 seconds

23.01 feet

Answer 1

1.03 seconds.

Reason: The vertex time is t = -b/(2a) = -33/(2·-16) = 33/32 ≈ 1.03125 s (max height ≈ 23.02 ft).
