Answer:
Step-by-step explanation:
I think the missing equation in your question is: h(t) = -16 + 16t + 480
Here is my answer:
As we know that the vertex form of a parabola, y=a + k where(h,k) is the vertex
h(t) = -16 + 16t + 480
= -16 ( + 480
= -16 + 484
So the vertex is ( , 484)
a. It take for Joseph second to reach his maximum height
b. The highest point that Joseph reached is the vertex of the function, it is 484 ft
c. Joseph hit the water after how many seconds?
<=> h(t) = 0
<=> -16 + 16t + 480 = 0
<=> t = second = 6 sec
Hope it will find you well
