Question

A dolphin jumps from the water at a initial velocity of 16 feet per second the equation h=-8t^2 + 16t models the dolphins height at any given time t what is the maxim height the dolphin jumps

Answer 1

Answer:

8 ft

Step-by-step explanation:

The maximum height will be at the maximum vertex

Find the t- coordinate of the vertex

$t_{vertex}$ = - $\frac{b}{2a}$ a = - 8 and b = 16

$t_{vertex}$ = - $\frac{16}{-16}$ = 1

The maximum height occurs at t = 1

Substitute t = 1 into the equation

h = - 8(1)² + 16(1) = - 8 + 16 = 8

Answer 2

Answer:

The answer to the equation -8t^2+16t = -48

Step-by-step explanation:

Add ''-8t^2'' to ''16t'' and the answer you get is ''-48''
