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:
D
Step-by-step explanation:
-2.25 x 3 = 6.75
the temperature decreased by 6.75 after 3 hours
Answer:
w = 13, 11, 12
Step-by-step explanation:
3 (15 - w)
3 (15 - 13)
3 (2)
w = 6
___
3 (15 - x)
3 (15 - 11)
3 (4)
w = 12
___
3 (15 - x)
3 (15 - 12)
3 (3)
w = 9
(hope this helps!)
Answer:
The answer is A.
Step-by-step explanation:
When you multiply by a negative number, you MUST change the sign.
Answer:
The smallest power of 10 that will exceed
is
.
Step-by-step explanation:
We can use the following approach to determine the smallest power of 10 that will exceed M. We can transform that number into scientific notation, which is of the form:
, 
Where:
- Integer part, formed by a digit, which is of the highest order.
- Decimal part, formed by a digit onwards.
- Power grade.
The smallest power of 10 that will exceed M is 
If
, then, the power grade is number of spaces that dot must be moved leftwards. In this case, dot must be moved 5 spaces on the left. The integer part is 1 and the decimal part is 1852665902. Then, the value of
in scientific notation is:

Then, the smallest power of 10 that will exceed
is
.
