It should be the last one because when you multiply 0x1/2 it’s 0 then add three and it’s three. And half of one is 1/2 plus three is 3 1/2. Half of 2 is 1 plus 3 is 4. Half of 3 is 1 1/2 plus 3 is 4 1/2.

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
