x^2-5x+5x-25 = x^2-25
Answer:
Option D. 
Step-by-step explanation:
we know that
If air resistance is ignored, the height h (in feet) of the ball t seconds after it is served is given by

where
g is the acceleration due to gravity which on earth is approximately equal to 32 feet / sec^2
V_0 is the initial velocity (when t = 0 )
H_0 is the initial height (when t = 0)
In this problem we have

substitute the given values


Rewrite

2 and 17/24
first find the common denominator of 24.
51 and 8/24 minus 48 and 15/24 equals 2 and 17/24
