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

The answer is -2a^4+4a^2b^2+5b^2a%

Answer:
x = 2.2
Step-by-step explanation:
-0.45x + 0.33 = -0.66
Subtract .33 from each side
-0.45x + 0.33-.33 = -0.66-.33
-.45x = -.99
Divide each side by -.45
-.45x./-.45 = -.99/-.45
x = 11/5
x = 2.2
