Answer:
Step-by-step explanation:
Equations:
x + y = 7
x - y = 3
Add and solve for "x":
2x = 10
x = 5
Solve for "y":
x + y = 7
5 + y = 7
y = 2
Answer:

Step-by-step explanation:
The derivative is defined as the term multiplied by its power and 1 subtracted from its power.
f(x)
The derivative of t is just 1. The second term is:

Answer:
hello your question is incomplete here is the complete question
Use cylindrical coordinates Find the volume of the solid that lies within both the cylinder x^2 + y^2=16 and the sphere x^2 + y^2 + Z^2= 81
Answer : ![\frac{4 \pi }{3} [729 - 65\sqrt{65} ]](https://tex.z-dn.net/?f=%5Cfrac%7B4%20%5Cpi%20%7D%7B3%7D%20%5B729%20-%2065%5Csqrt%7B65%7D%20%5D)
Step-by-step explanation:
The given data
cylinder = x^2 + y^2 = 16
sphere = x^2 + y^2 +z^2 = 81
from the given data the solid is symmetric around the xy plane hence we will calculate half the solid volume above the plane then multiply the sesult by 2
Note : we are restricting our attention to the cylinder x^2 + y^2 = 16 and also finding the volume inside the sphere which gives bound on the z-coordinate as well
the r parameter goes from 0 to 4

Answer is on the picture and all the work that I showed
The answer is true.
5.4 divided by 0.6 = 9
12.6 divided by 1.4 = 9
