Sorry im a little late but here's how i did it.
Hope this helps! :)
Proving Vertical Angles Are Congruent
1 answer:
The angle ∠22 and angle ∠24 are congruent because they are vertically opposite angles.
<h3>What is an angle?</h3>The angle is the distance between the intersecting lines or surfaces. The angle is also expressed in degrees. The angle is 360 degrees for one complete spin.
Vertically opposite angle – When two lines intersect, then their opposite angles are equal.
Linear angle – If the total of two angles is 180 degrees, they are said to be linear angles.
The statements are given below.
∠22 = ∠24 (vertically opposite angle)
∠22 + ∠23 = 180 (linear angle)
The diagram is given below.
More about the angled link is given below.

First part of question:
Find the general term that represents the situation in terms of k.
The general term for geometric series is:
= the first term of the series
= the geometric ratio
would represent the height at which the ball is first dropped. Therefore:
We also know that the ball has a rebound ratio of 75%, meaning that the ball only bounces 75% of its original height every time it bounces. This appears to be our geometric ratio. Therefore:
Our general term would be:
Second part of question:
If the ball dropped from a height of 235ft, determine the highest height achieved by the ball after six bounces.
represents the initial height:
represents the number of times the ball bounces:
Plugging this back into our general term of the geometric series:
represents the highest height of the ball after 6 bounces.
Third part of question:
If the ball dropped from a height of 235ft, find the total distance traveled by the ball when it strikes the ground for the 12th time.
This would be easier to solve if we have a general term for the <em>sum </em>of a geometric series, which is:
We already know these variables:
Therefore:
