A rocket is launched from earth and follows the equation y = -32x2+640x. Use completing the square to get this equation into vertex form. Answer the following questions: What was the starting height of the rocket? How high did the rocket go? When did the rocket reach its maximum height? When did the rocket hit the ground?

1. 16.64

a^2+b^2=c^2

pr^2=pq^2+qr^2

pr^2=14^2+ 9^2

pr^2=196+81

pr= sqr root of 277

16.64

2. 11.31

c^2-a^2=b^2

18^2- 14^2=b^2

b^2=324-196

b=sqr root of 126

b=11.31

hope it ! (btw im in connections academy to, good luck! )

mtrs.

step-by-step explanation:

first sa=180 square meters

as it is given that

putting the value of sa

mtrs.

now, when sa = 120 sq mtrs. using the formula we get

mtrs.

the side of cube with surface area 180 sq mtrs. is longer by side of cube with surface area 12 sq. mtrs. by

mtrs..
