1. The function

is a parabola of the form

. The the formula for the axis of symmetry of a parabola is

. We can infer from our function that

and

, so lets replace those values in our formula:





We can conclude that to the left of the line of symmetry the ball is reaching its maximum height, and to the right of the line of symmetry the ball is falling.
2. Lets check how much time the ball takes to reach its maximum height and return to the ground. To do that we are going to set the height equal to zero:



or


or

From our previous point we know that the ball reaches its maximum time at

, which means that <span>
it takes 1.5 seconds to reach the maximum height and 1.5 seconds to fall back to the ground.</span>

I’m not 100% bc/ I learned this last semester, but I think it’s B. So sorry if I’m wrong. I think this bc/ 0.04 is the interest rate as a percent, 4 is the time, 200 is the amount of money, and the one shows that it is exponential growth.
I think the answer is B but I am not sure
The simple interest on the principal amount of $725 at a rate of 3.25% for 6 months is $736.78
<h3>What is simple interest? </h3>
Simple interest is calculated on the loan principal amount or the initial deposit into a savings account. It can be determined by using the formula:

where:
- P = principal = $725
- R = rate = 3.25%
- T = time = 6 months = 0.5 years

S.I = $736.78
