Step-by-step explanation:
s = -4.9t² + 49t
The vertex of the parabola is at t = -b/(2a).
t = -49 / (2 × -4.9)
t = 5
The rocket reaches its maximum height after 5 seconds.
Here the graph and what else you need
2+2=4 because 1+1+1+1 equals and those 2 problems are the same. You got to at least know 1+1+1+1.!
(-3/4)^10 please mark as brainiest :)
