Answer:
Step-by-step explanation:
think of the flight of a small rocket..  what does it seem like the parabola would look like?  down means it looks like a cup or glass , upside down , up mean a cup or glass right side up. 
when t = 0  the rocket is at 25, so that's the initial height
it's velocity is initially 200 m/s
put equation from std. form to vertex form
y = a + bx +c       =>       y = a(x - h ) ^2 + k
 + bx +c       =>       y = a(x - h ) ^2 + k
h = -4.9 + 200t + 25  =>h = -4.9(t - 20.41)^2 + 2,065.82
 + 200t + 25  =>h = -4.9(t - 20.41)^2 + 2,065.82
(h,k) =  (20.41 , 2065.82)
 
        
             
        
        
        
I believe the numbers are 63 and 65.
        
             
        
        
        
Answer:
1.53x−14.23
Step-by-step explanation:
<em>simplify: </em>
5.03x−8.03−(3.5x+6.2)
<em>Distribute the Negative Sign:</em>
=5.03x−8.03−1(3.5x+6.2)
=5.03x−8.03−1(3.5x)+(−1)(6.2)
=5.03x−8.03−3.5x−6.2
<em>Combine Like Terms:</em>
=5.03x−8.03+−3.5x−6.2
=(5.03x−3.5x)+(−8.03−6.2)
=1.53x−14.23
