Answer:
5 seconds it will hit the water.
Step-by-step explanation:
y=-16t²+400
add -16t² to both sides
-16t²=-400
divide both sides by 16
t²=-25
t=√25
t=5
You would have to Multiply 50 by 2 and then Multiply the answer to 300.
Plug in -3 for x into the equation.
(1/4)^-3
And solve
(1/4)^-3 = 64
3rd one. The circle is on 7 and is going to the left.
The answer is 3 because all you have to do is plug in the answer and then you have to solve the answer and go from there.
