Answer:
3x2|9x+18|+8|9x+18|3x2|9x+18|+8|9x+18|
How many do you want ? There are an infinite number of them.
You can find a huge number of them with your calculator
Here are a few (2 for each point I'll earn):
5³ = 125
6³ = 216
7³ = 343
8³ = 512
9³ = 729
10³ = 1,000
11³ = 1,331
12³ = 1,728
13³ = 2,197
14³ = 2,744
.
.
etc.
Answer: (x+7)^2 + (y-4)^2 = 121 or (x+7)^2 + (y-4)^2 = 11^2
Step-by-step explanation:
Equation of the circle is:
, which is the center
and the radius 
-Place the center (-7,4) and radius 11 onto that equation:
(if simplified radius needed)
or

Answer:




The absolute difference is:

If we find the % of change respect the before case we have this:

So then is a big change.
Step-by-step explanation:
The subindex B is for the before case and the subindex A is for the after case
Before case (with 500)
For this case we have the following dataset:
500 200 250 275 300
We can calculate the mean with the following formula:

And the sample deviation with the following formula:

After case (With -500 instead of 500)
For this case we have the following dataset:
-500 200 250 275 300
We can calculate the mean with the following formula:

And the sample deviation with the following formula:

And as we can see we have a significant change between the two values for the two cases.
The absolute difference is:

If we find the % of change respect the before case we have this:

So then is a big change.
