Answer:
C. ![9\pi](https://tex.z-dn.net/?f=9%5Cpi)
Step-by-step explanation:
We proceed to solve for
by the Pythagorean Theorem:
(1)
![x^{2} + 2\cdot x + 1 = (x^{2}-2\cdot x + 1) + (4\cdot x^{2}-16\cdot x + 16)](https://tex.z-dn.net/?f=x%5E%7B2%7D%20%2B%202%5Ccdot%20x%20%2B%201%20%3D%20%28x%5E%7B2%7D-2%5Ccdot%20x%20%2B%201%29%20%2B%20%284%5Ccdot%20x%5E%7B2%7D-16%5Ccdot%20x%20%2B%2016%29)
![x^{2} + 2\cdot x + 1 = 5\cdot x^{2}-18\cdot x + 17](https://tex.z-dn.net/?f=x%5E%7B2%7D%20%2B%202%5Ccdot%20x%20%2B%201%20%3D%205%5Ccdot%20x%5E%7B2%7D-18%5Ccdot%20x%20%20%2B%2017)
![4\cdot x^{2} -20\cdot x + 16 = 0](https://tex.z-dn.net/?f=4%5Ccdot%20x%5E%7B2%7D%20-20%5Ccdot%20x%20%2B%2016%20%3D%200)
![(2\cdot x)^{2} -10\cdot (2\cdot x) + 16 = 0](https://tex.z-dn.net/?f=%282%5Ccdot%20x%29%5E%7B2%7D%20-10%5Ccdot%20%282%5Ccdot%20x%29%20%2B%2016%20%3D%200)
![(2\cdot x -8)\cdot (2\cdot x -2) = 0](https://tex.z-dn.net/?f=%282%5Ccdot%20x%20-8%29%5Ccdot%20%282%5Ccdot%20x%20-2%29%20%3D%200)
There are two different solutions:
, ![x_{2} = 1](https://tex.z-dn.net/?f=x_%7B2%7D%20%3D%201)
A solution of
is considered realistic when the length of every side of the triangle is a not negative number.
![x_{1} = 4](https://tex.z-dn.net/?f=x_%7B1%7D%20%3D%204)
![UV = 2\cdot (4) - 4](https://tex.z-dn.net/?f=UV%20%3D%202%5Ccdot%20%284%29%20-%204)
![UV = 4](https://tex.z-dn.net/?f=UV%20%3D%204)
![WU = 4 - 1](https://tex.z-dn.net/?f=WU%20%3D%204%20-%201)
![WU = 3](https://tex.z-dn.net/?f=WU%20%3D%203)
![WV = 4 + 1](https://tex.z-dn.net/?f=WV%20%3D%204%20%2B%201)
![WV = 5](https://tex.z-dn.net/?f=WV%20%3D%205)
![x_{2} = 1](https://tex.z-dn.net/?f=x_%7B2%7D%20%3D%201)
![UV = 2\cdot (1) - 4](https://tex.z-dn.net/?f=UV%20%3D%202%5Ccdot%20%281%29%20-%204)
![UV = -2](https://tex.z-dn.net/?f=UV%20%3D%20-2)
![WU = 1 - 1](https://tex.z-dn.net/?f=WU%20%3D%201%20-%201)
![WU = 0](https://tex.z-dn.net/?f=WU%20%3D%200)
![WV = 1 + 1](https://tex.z-dn.net/?f=WV%20%3D%201%20%2B%201)
![WV = 2](https://tex.z-dn.net/?f=WV%20%3D%202)
The only realistic set of solutions is for
, and the radius of the circle is represented by the line segment
: ![r = 3](https://tex.z-dn.net/?f=r%20%3D%203)
And the area of the circle (
) is calculated from the following formula:
![A = \pi\cdot r^{2}](https://tex.z-dn.net/?f=A%20%3D%20%5Cpi%5Ccdot%20r%5E%7B2%7D)
![A = \pi\cdot (9)](https://tex.z-dn.net/?f=A%20%3D%20%5Cpi%5Ccdot%20%289%29)
![A = 9\pi](https://tex.z-dn.net/?f=A%20%3D%209%5Cpi)
The correct answer is C.
They would drive 195 miles in 3 hour
Answer:
If you deposit money, your bank account shows it as +3
3 degrees below zero = - 3 o F which is darn cold.
3 floors below ground level = - 3 floors below ground level
3 feet above sea level = +3 feet
3 degrees about 0 = + 3
3 dollars lost = -3 dollars.
