Will give brainliest answer.

A ball is thrown into the air with an upward velocity of 28 ft/s. Its height (h) in feet after t seconds is given by the function h = - 16t² + 28t + 7. How long does it take the ball to reach its maximum height? What is the ball's maximum height? Round to the nearest hundredth, if necessary.

A - Reaches a maximum height of 7 feet after 1.75 seconds.

B - Reaches a maximum height of 43.75 feet after 0.88 seconds.

C - Reaches a maximum height of 17.5 feet after 0.88 seconds.

D - Reaches a maximum height of 19.25 feet after 0.88 seconds.
