Answer:

Step-by-step explanation:
We are trying to evaluate this integral.

The first thing that we have to do is understand this region in the plane.

If you graph it looks something like the photo I join.
Now we need to describe that same region in polar coordinates.
That same region in polar coordinates would be

Now remember that when we do the polar transformation we use the following formula

Then our integral would be

Answer:
-440, -4440, -44440, -444440, -4444440
Step-by-step explanation:
First, let's find values for x which start is a -2 and end with a 2.
-22
-222
-2222
-22222
-222222
Now we can find the y value by multiplying each term by 20.
-22 --> -440
-222 --> -4440
-2222 --> -44440
-22222 --> -444440
-222222 --> -4444440
You need to specify the statement needed to use the equation. Thank you. I will then answer it if needed.
The answer is 19. You have to do 1/4 x 76/1 which is basically 76 divided by 4, which gives you 19.
