This should be recognized as the difference of perfect squares which is of the form:
(a^2-b^2) and the difference of squares always factors to:
(a-b)(a+b)  in this case:
(3x-8)(3x+8)

Answer:

Step-by-step explanation:
We know that  tan(x) is defined as  sin(x)/cos(x):


1/0 is undefined as 0 is in the denominator
 
        
             
        
        
        
Hello,
g=9.81m/s²= 9.81/0.3048 =32.18.. ft/s² rounded to 32
h=-g/2*t²+vt+h0
if t=0,h=0 ==>h0=0
==>h=-16*t²+vt
50 ft in 2.5s ==> 25 ft in 1.25s
25=-16*1.25²+v*1.25
==>v=50/1.25=40
Equation h=-16t²+40*t
