Intersecting chords theorem:
![7\cdot7=10x](https://tex.z-dn.net/?f=7%5Ccdot7%3D10x)
i.e. when two chords intersect, the products of the resulting line segments' lengths are equal. Then
![10x=49\implies x=\dfrac{49}{10}=\boxed{4.9}](https://tex.z-dn.net/?f=10x%3D49%5Cimplies%20x%3D%5Cdfrac%7B49%7D%7B10%7D%3D%5Cboxed%7B4.9%7D)
1 quart = 32 fluid ounces.
So, 5 quarts = ? fluid ounces.
Lets solve to find ?.
5 × 32 = 160
So, Nadine bout 160 fluid ounces (5 quarts) or oil for her car.

Answer:
Option C. (0.93,0.36)
Step-by-step explanation:
we know that
The coordinates (x,y) of a point of the unit circle are given by the formula
![x=rcos(\theta)](https://tex.z-dn.net/?f=x%3Drcos%28%5Ctheta%29)
![y=rsin(\theta)](https://tex.z-dn.net/?f=y%3Drsin%28%5Ctheta%29)
Remember that r is the radius of circle and the unit circle has r=1 unit
so
![x=cos(\theta)](https://tex.z-dn.net/?f=x%3Dcos%28%5Ctheta%29)
![y=sin(\theta)](https://tex.z-dn.net/?f=y%3Dsin%28%5Ctheta%29)
For ![\theta=21\°](https://tex.z-dn.net/?f=%5Ctheta%3D21%5C%C2%B0)
substitute
![x=cos(21\°)=0.93](https://tex.z-dn.net/?f=x%3Dcos%2821%5C%C2%B0%29%3D0.93)
![y=sin(21\°)=0.36](https://tex.z-dn.net/?f=y%3Dsin%2821%5C%C2%B0%29%3D0.36)
therefore
The coordinates of the point are (0.93,0.36)
