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.

the solution is x=1

step-by-step explanation:

we are given our   equation as

let's assume

left side function is

right side function is

now, we can draw graph

and then we can get intersection point

the intersection point will be solution

so, the solution is

x=1

i believe the answers 600m
