I'm sure you should look it up on Google I'm pretty sure that that would help you more than this stupid app OK look it up on Google or a Siri it will help you a lot better
Answer:

Step-by-step explanation:
The equation of a circle:

<em>(h, k)</em><em> - center</em>
<em>r</em><em> - radius</em>
<em />
We have diameter endpoints.
Half the length of the diameter is the length of the radius.
The center of the diameter is the center of the circle.
The formula of a distance between two points:

Substitute the coordinates of the given points (-8, 2) and (-2, 6):

The radius:

The formula of a midpoint:

Substitute:


Finally:

Answer: b is the answer
Step-by-step explanation:
2400-1200=1200
Answer: 8 = 23 (-8)4 = (23)4 = 212
1/(2048x)
Step-by-step explanation:Negative number raised to an even power is positive
For example let's look at (-7)6 , where (-7) , a negative number, is raised to 6 , an even exponent :
(-7)6 can be written as (-7)•(-7)•(-7)•(-7)•(-7)•(-7)
Now, using the rule that says minus times minus is plus, (-7)6 can be written as (49)•(49)•(49) which in turn can be written as (7)•(7)•(7)•(7)•(7)•(7) or 76 which is positive.
We proved that (-7)6 is equal to (7)6 which is a positive number
Using the same arguments as above, replacing (-7) by any negative number, and replacing the exponent 6 by any even exponent, we proved which had to be proved
Dividing exponential expressions : x3 divided by x4 = x(3 - 4) = x(-1) = 1/x1 = 1/x
Final result :
1/2048x
