An increase of 2% per year means the population is multiplied by 1.02 each year. Your exponential function with a base of 1.02 and a scale factor of 5.3 (billion) will look like this:
... q(t) = 5.3×1.02^t

= 37.5%
If you are using a calculator, simply enter 30÷80×100 which will give you 37.5 as the answer.
Answer:
<h3>After 0.75 seconds the ball would reach it's maximum height of 16 feet.</h3>
Step-by-step explanation:
We are given a quadratic function
for height of the ball after T seconds.
We need to find the time T when ball would reach at it's maximum height and also maximum height of the ball.
In order to find the maximum height of the ball, we need to find the x-coordinate of the vertex.
x-coordinate of the vertex is given by formula
x =
.
For the given quadratic a=-16 and b= 24.
Plugging a=-16 and b= 24 in above formula of x-coordinate of the vertex.
.
Now, plugging x=0.75 in given quadratic
, we get
![-16(0.75)^2+24(0.75)+7](https://tex.z-dn.net/?f=-16%280.75%29%5E2%2B24%280.75%29%2B7)
= -16(0.5625)+18+7
= -9+25
=16.
<h3>Therefore, after 0.75 seconds the ball would reach it's maximum height of 16 feet.</h3>
