The answer to the question is y=<span><span><span>−<span>x2</span></span>+<span>10x</span></span>−<span>14</span></span>
The correct answer is A.
That is because the whole paragraph talks about a model car that they are testing but this student is wondering about roller coasters.
Hope this helps :)
Given:
In triangle ABC, point D is the centroid, and BD = 6.
To find:
The measure of side BE.
Solution:
We know that the centroid divides each median in 2:1.
In the given figure BE is a median and point D is the centroid. It means point D divides the segment BE in 2:1.
Let BD and DE are 2x and x respectively.
We have, BD = 6 units.
![2x=6](https://tex.z-dn.net/?f=2x%3D6)
![x=\dfrac{6}{2}](https://tex.z-dn.net/?f=x%3D%5Cdfrac%7B6%7D%7B2%7D)
![x=3](https://tex.z-dn.net/?f=x%3D3)
Now,
![BE=BD+DE](https://tex.z-dn.net/?f=BE%3DBD%2BDE)
![BE=6+x](https://tex.z-dn.net/?f=BE%3D6%2Bx)
![BE=6+3](https://tex.z-dn.net/?f=BE%3D6%2B3)
![BE=9](https://tex.z-dn.net/?f=BE%3D9)
Therefore, the measure of side BE is 9 units.
