true I'm positive that the correct answer
Answer:

Step-by-step explanation:
we know that
An isosceles triangle has two equal sides and two equal angles
so
The perimeter of triangle is equal to

Eliminate parenthesis

Combine like terms

<span>y = –16x2 + 24x + 1
</span>(downward parabola)
it is a height
when the ball is 6ft above the ground
- Average Rate of Change/Slope Formula:

So using points (6,71) and (2,y), and the slope of 15, plug them into the slope formula as such:

From here we can solve for y. Firstly, solve the subtraction:

Next, multiply both sides by 4:

Next, subtact both sides by 71:

Lastly, multiply both sides by -1, and <u>your final answer will be
, or A.</u>
