Choose the correct answer and EXPLAIN. The height in feet of a golf ball hit into the air is given by h=−16t2+64t rest of question in file A) 5 seconds
B) 9 seconds
C) 2 seconds
D) 4 minutes

The answer is C) 2 seconds

Step-by-step explanation:

The trajectory of the ball is a downward parabola passing by the origin. The ball reaches the maximum height at the parabola's vertex. On the coordinate grid (t, h)

t = -b/2a = -64/-32 = 2 sec

2 seconds

Step-by-step explanation:

t = -b/2a = -64/-32

step-by-step explanation:

stew:

we need to find the slope

m = (y2-y1)/ (x2-x1)

    = (2650-795)/(10-3)

    = 1855/7

connie:

we need to find the slope

m = (y2-y1)/ (x2-x1)

we have two points (0,0) and (4,800)

m = (800-0)/(4-0)

  m = 800/4
