17. A bottlenose dolphin jumps out of the water. The path the dolphin Travels can be
modeled by h = -0.2d2 + 2d, where h represents the height of the dolphin and d
represents horizontal distance.
a. What is the maximum height the dolphin reaches?
b. How far did the dolphin jump?

a. 5 units

b. 5 units

Step-by-step explanation:

Given:

The path the dolphin Travels can be  modelled by where  h represents the height of the dolphin and d  represents horizontal distance.

To find: maximum height that the dolphin reaches and the distance covered by dolphin

Solution:

Differentiate with respect to

To find the critical point, put

Differentiate again with respect to

So, is a point of maxima

a. 5 units

b. 5 units
