Answer:
a)The sunglasses hit the ground at t=0 seconds
b)The maximum height h(t) = 1600feet
Step-by-step explanation:
<u><em>Step(i):-</em></u>
Given that the polynomial function
h(t) = -16 t² + 1600 ...(i)
Differentiating equation (i) with respective to 't' , we get

Equating zero

⇒ -32t =0
⇒ t =0
The sunglasses hit the ground at t=0 seconds
<u><em>Step(ii):-</em></u>
Again differentiating with respective to 't', we get

The maximum height at t=0
h(t) = -16 t² + 1600
h(t) = 1600feet

By using the information given on the graph, we can see that a = 3.
<h3>
How to find the value of a?</h3>
Here we have an exponential of the form:

And by looking at the graph, it passes through (0, 4) and (2, 36), so we can write:

From the first equation we get that p = 4, replacing that on the second one we get:

So we conclude that a = 3.
