Answer:
333.5 feet
Step-by-step explanation:
In the first trip to the ground, the ball goes 29 feet. After that, it bounces until it reaches 0.84 times 29 feet and goes back to ground the same distance. It makes the total distance:
For the second bounce, the next height will be 0.84 of the previous one, that is
and the total distance:
The game continues such that for n bounds the total distance will be
When n goes to infinity, the sum becomes a sum of an infinite series
In our case, a=0.84 and r=0.84
The sum of all bounces will be
![S=29+58\sum 0.84^n=29+\frac{0.84}{1-0.84}=333.5\ feet](https://tex.z-dn.net/?f=S%3D29%2B58%5Csum%200.84%5En%3D29%2B%5Cfrac%7B0.84%7D%7B1-0.84%7D%3D333.5%5C%20feet)
The sum of the expression (–x² + x) and (x² – 3x – 1) will be –2x – 1. Then the correct option is D.
<h3>What is Algebra?</h3>
The analysis of mathematical representations is algebra, and the handling of those symbols is logic.
The expression can be written as
(–x² + x) and (x² – 3x – 1)
Then the sum of the expression (–x² + x) and (x² – 3x – 1) will be
(–x² + x) + (x² – 3x – 1) = –2x – 1
Then the correct option is D.
