Front

What is the Vertex of the graph?

Back

(-4, -4)

Front

The height of an object thrown into the air can be modeled by the formula h(t) = -16t² + 70t + 95, where h(t) is in feet after t seconds.
What is the height of the object after 5 seconds?

Back

45 feet

Front

A ball is thrown into the air with an upward velocity of 64 ft/s. Its height, h, after t seconds is given by the function h = -16t² + 64t + 960. How many seconds did it take for the ball to reach its maximum height?

Back

2 seconds

Front

A ball is thrown into the air with an upward velocity of 64 ft/s. Its height, h, after t seconds is given by the function h = -16t^2 + 64t + 960. When did the ball hit the ground?

Back

10 seconds

Front

When will a model rocket launched with an initial speed of 88 feet per second be 40 feet high?

Back

0.5 sec, 5 seconds

Front

A dolphin jumps from the water at an initial velocity of 16 feet per second. The equation h = -16t² + 80t models the dolphin's height at any given time, t. What is the maximum height the dolphin jumps?

Back

100 feet

Front

The height of an object thrown into the air can be modeled by the formula h(t) = -16t² + 70t + 95, where h(t) is in feet after t seconds.
What is the height of the object after 5 seconds?
