Notice that Given that
is an ellipse, consider a conversion to polar coordinates:

The Jacobian for this transformation is

with determinant 
Then the integral in polar coordinates is

where you can evaluate the remaining integral by substituting
and

Answer:A
Step-by-step explanation:
first you use the lmnp and pqno to get our full answer
Answer:
1/7
Step-by-step explanation:
Since we do not know the number let us use the alphabet A to represent the unknown number
A × 1/3= 1/21
A/3= 1/21
Cross multiply both sides
A×21= 3×1
21A= 3
Divide both sides by the coefficient of A which is 21
21A/21=3/21
A=1/7
Hence the unknown number is 1/7
B) y=34.84x-2054 I believe that is the right answer
