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=−16t2+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)

Answer 1

1.03 seconds

Reason: The time of the vertex for h = -16t^2 + 33t + 6 is t = -b/(2a) = 33/(32) = 1.03125 ≈ 1.03 s.
