On top of a hill, a rocket is launched from a distance 80 feet above a lake. The rocket will fall into the lake after its engine
lisov135 [29]
For this case we have the following equation:
 h = -16t2 + 64t + 80
 To find the maximum height, we derive the equation:
 h = -32t + 64
 We match zero:
 -32t + 64 = 0
 We clear t:
 t = 64/32
 t = 2
 We substitute the value of t in the given equation:
 h (2) = -16 * (2) ^ 2 + 64 * (2) + 80
 h (2) = 144
 Answer:
 
The maximum height is 144 feet and the time to reach this height is 2 seconds.

Which of the following polynomial functions is graphed below?
Olegator [25]

Answer: B. f(x)=(x+4)(x-2)^2(x+3)

Step-by-step explanation:

in the graph there's two negative x value and one positive x value

so the function should be in a form of f(x)= (x+a) (x-b)^2 (x+c)

the one with negative value has a square, (x-b)^{2}, because that's where the y = 0 (the point is hitting the (x,0))
