Cosine = adjacent/hypotenuse
Cos A = 3/4.24
Cos B = 3/4.24
Since they are equivalent, Cos A/Cos B = 1
I may be wrong but I got x³- 2 + 12.
Step-by-step explanation:
The height of the rocket y in feet is related to the time after launch, x in seconds, by the given equation i.e.
......(1)
It is required to find the maximum height reached by the rocket. For maximum height put
.
So,

Put x = 5.15 in equation (1).

So, the maximum height reached by the rocket is 503.39 m.
