A ball was kicked into the air from a balcony 20 feet above the ground, and the ball’s height above the ground, in feet, t secon

Svet_ta [14]

$h(t)=20-16t^2+32t \\ \Downarrow \\ h(t)=-16t^2+32t+20 \\ \\
a=-16 \\ b=32$

The maximum height is the y-coordinate of the vertex (x,y) of the parabola.
First find the x-coordinate using the formula:
$x=\frac{-b}{2a}=\frac{-32}{2 \times (-16)}=\frac{-32}{-32}=1$

Now plug the value into the equation and find the y-coordinate:
$y=h(x)=h(1)=-16 \times 1^2+32 \times 1+20=-16+32+20=36$

The maximum height is 36 feet.

Answer:

The population of 75 hours from now would be 40,000.

Step-by-step explanation:

The reason for this is because your initial number is 10,000 and when 25 hours pass by, your population would be 20,000. Another 25 hours pass by, and then your population would be 40,000. If you multiply 25 by 3, you will notice 75 hours have just passed, so your answer would be 40,000.
