The equation of a circle is x2+y2−12x+6y+20=0 .

what is the radius of the circle?

r = ?

The radius is r=5 units

Step-by-step explanation:

we know that

The equation of the circle in standard form is equal to

where

(h,k) is the center and r is the radius

we have

Convert to standard form

Group terms that contain the same variable, and move the constant to the opposite side of the equation

Complete the square twice. Remember to balance the equation by adding the same constants to each side

Rewrite as perfect squares

therefore

The center is the point (6,-3) and the radius is r=5 units

incomplete question. how do you expect anyone to you when you do not post the question in its entirety?

median is the value separating the higher half of a data sample, a population or probablity distribution from the lower half.

step-by-step explanation:

say you have 3,8,7,3,1,9,8 order them from lowest to highest

if orderd it would be 1,3,3,7,8,8,9 now you take away from the lowest and the highest until you end up in the middle.

so you would remove the 1 and 9 leaving you with 5 digits remaining

when you've reached the middle that would be your answer so in this case the answer is 7

if there were two numbers left say 7 and 5 you'd and them together so 12 then divide by 2 witch would equal 6 so the answer would be 6

good luck on that project hoped i you at all
