Answer:
The volume is 
cubic units.
Step-by-step explanation:
The given curve is
The given line is
Equate both the functions to find the intersection point of both line and curve.
According to washer method:
![V=\pi \int_{a}^{b}[f(x)^2-g(x)^2]dx](https://tex.z-dn.net/?f=V%3D%5Cpi%20%5Cint_%7Ba%7D%5E%7Bb%7D%5Bf%28x%29%5E2-g%28x%29%5E2%5Ddx)
Using washer method, where a=0 and b=1, we get
![V=\pi \int_{0}^{1}[(7x)^2-(7x^6)^2]dx](https://tex.z-dn.net/?f=V%3D%5Cpi%20%5Cint_%7B0%7D%5E%7B1%7D%5B%287x%29%5E2-%287x%5E6%29%5E2%5Ddx)
![V=\pi \int_{0}^{1}[49x^2-49x^{12}]dx](https://tex.z-dn.net/?f=V%3D%5Cpi%20%5Cint_%7B0%7D%5E%7B1%7D%5B49x%5E2-49x%5E%7B12%7D%5Ddx)
![V=49\pi \int_{0}^{1}[x^2-x^{12}]dx](https://tex.z-dn.net/?f=V%3D49%5Cpi%20%5Cint_%7B0%7D%5E%7B1%7D%5Bx%5E2-x%5E%7B12%7D%5Ddx)
![V=49\pi [\frac{x^3}{3}-\frac{x^{13}}{13}]_0^1](https://tex.z-dn.net/?f=V%3D49%5Cpi%20%5B%5Cfrac%7Bx%5E3%7D%7B3%7D-%5Cfrac%7Bx%5E%7B13%7D%7D%7B13%7D%5D_0%5E1)
![V=49\pi [\frac{1^3}{3}-\frac{1^{13}}{13}-(0-0)]](https://tex.z-dn.net/?f=V%3D49%5Cpi%20%5B%5Cfrac%7B1%5E3%7D%7B3%7D-%5Cfrac%7B1%5E%7B13%7D%7D%7B13%7D-%280-0%29%5D)
![V=49\pi [\frac{1}{3}-\frac{1}{13}]](https://tex.z-dn.net/?f=V%3D49%5Cpi%20%5B%5Cfrac%7B1%7D%7B3%7D-%5Cfrac%7B1%7D%7B13%7D%5D)
Therefore the volume is cubic units.
Answer:
Answer: A and B.
Step-by-step explanation:
Supplementary angles are a pair of angles that add 180 degrees.
A. Show two angles that form a 180 degree angle, so they are supplementary.
B. This angles add 180 degrees, so they are supplementary.
C. The two angles add 90 degrees, so they are complementary, not supplementary.
D. This angles add 90 degrees, so they are complementary, not supplementary.

Answer:
1. A
2. B
Step-by-step explanation:
1. Only option A creates that graph, the other options are either backwards or are on top of each other.
2. Because the two lines are parallel, and do not intersect at all, there will be 0 solutions.
