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
 h = -16t² + 64t + 960.
How many seconds did it take for the ball to reach its maximum height?

• 10 seconds

• 64 seconds

• 960 seconds

• 2 seconds

If a ball if thrown into the air is represented by the function
h(t) = -16t²+80t, where t represents the time in seconds and h(t) is the height of the ball in feet. Find the time it will take to reach its maximum height. 

• 8 mins

• 2.5 seconds

• 5 seconds

• 604 seconds

Which option shows what quadratics in standard form look like?

• a = 4

  b = 8

  c = 3

• a = 4

  b = -8

  c = -3

• a = 4

  b = -8

  c = 3

• a = 4

  b = 8

  c = -3

Solve
a² + 2a - 24 = 0

• a = -6, 4

• a = 6, -4

• a = 12, -2

• a = 8, -3
