What is the Vertex of the graph?

• (-4, -4)

• (0, 0)

• (-8, 0)

• (-2, -3)

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?

• 95 feet
• 45 feet
• 70 feet
• 171.56 feet

A ball is thrown into the air with an upward velocity of 100 ft/s. Its height, h, after t seconds is given by the function

• 10 seconds
• 2 seconds
• 5 seconds
• 7 seconds
