A diver is standing on a platform 30 feet above the pool. He jumps from the platform with an initial upward velocity of 10 ft/s. Use the formula h = -16ť+ ut + s, where h is his height
above the water, t is his time, v is the starting upward velocity, and s is the starting height to
determine which of the following statements is true.
A. The diver will reach his maximum height approximately 0.3 seconds after he fives. This is a

zero of the function.
B. The diver will hit the water approximately 1.7 seconds after he dives. This is the t-value of
the vertex of the function.
C. The diver will reach his maximum height 1.7 seconds after he dives. This is the t-value of the
vertex of the function.
D. The diver will hit the water approximately 1.7 seconds after he dives. This is a zero of the
function.
