Answer:
True
Step-by-step explanation:
If any number is multiplied by a negative in this case, the answer will of course be negative
1 ) 9 x + 18 > 9 x - 27
9 x - 9 x > - 27 - 18
0 * x > - 45
Always true
2 ) 6 x - 13 < 9 x - 12
6 x - 6 x < - 12 + 13
0 * x < 1
Always true
3 ) - 6 ( 2 x - 10 ) + 12 x ≤ 180
- 12 x + 60 + 12 x ≤ 180
0 * x ≤ 180 - 60
0 * x ≤ 120
Always true.
The value of the integral is
<h3>How to evaluate the integral?</h3>
The expression is given as:
Rewrite the integral as:
As a general rule, we have:
By comparison, we have:
P = 9
Q = 2
R = z
By the divergence theorem, we have:
F = Pi + Qj + Rk
So, we have:
F = 9i + 2j + zk
Differentiate
F' = 0 + 0 + 1
F' = 1
The volume of a sphere is:
Where:
r = F' = 1
So, we have:
Evaluate
This means that:
Hence, the value of the integral is
