Guys please help me solve this its so stressful

Given:-

A parabola attain maximum height at the vertex: formula to find x-coordinate of vertex is,

plug in a=-5 and b=10

so,

Now plug in x=1 to get maximum height,

so, maximum heigh reached by the rocket was 25 yards

Rocket will hit the ground when y=0

So,

quadratic formula is,

plug in a=1, b=-2,and c=-4

So, it takes 3.2 seconds to hit the ground.

OAmalOHopeO

it is c, trust i got your back lol

step-by-step explanation:

step-by-step explanation:

we have

using a graphing tool

see the attached figure

this is a quadratic equation (vertical parabola) open up

the vertex is a > vertex

the domain of the function is all real > interval (-∞,∞)

the range of the function is the > [-6.125,∞)

the function has two x->   and

the function is increasing over the > (0.25,∞)

the function is decreasing over the > (-∞,0.25)
