Y - 2 = -3/4 (x - 6)
y = -3/4 (x - 6) + 2
When, x = -2,
y = -3/4 (-2 - 6) + 2 = -3/4 (-8) + 2 = 6 + 2 = 8
One point is (-2, 8)
When, x = 2,
y = -3/4 (2 - 6) + 2 = -3/4 (-4) + 2 = 3 + 2 = 5
Another point is (2, 5)

A dolphin jumps out of the water with
Mandarinka [93]

Answer:

t=1.25\ sec

Step-by-step explanation:

we have

h(t)=-16t^{2}+20t

where

t is the time in seconds

h is the dolphin's height in feet

we know that

When the dolphin return to the water the value of h(t) is equal to zero

so

For h(t)=0

0=-16t^{2}+20t

16t^{2}=20t

Simplify

16t=20

t=\frac{20}{16}

t=\frac{5}{4}=1.25\ sec

see the attached figure to better understand the problem
