Answer:
-12x+20
Step-by-step explanation:
Note that when you are dividing, and there is the same base, subtract
3^2/3^4 = 3^(2 - 4) = 3^(-2)
3^(-2) = 1/(3^2)
Simplify
1/(3^2) = 1/9
1/9 is your answer
hope this helps
Answer:
The volume of the solid = π²
Step-by-step explanation:
As per the given data of the questions,
The diameter of each disk is
D = 2 sin(x) - 2 cos(x)
So its radius is
R = sin(x) - cos(x).
The area of each disk is
Now,
Integrate from , we get volume:
After integrate without limit we get
Now after putting the limit, we get
V = π²
Hence, the required volume of the solid = π²
