A circle has the equation x2+ 12x+y2 -8y = 73. (a) Determine the coordinates of the center of the circle. Show how you arrived at
your answer.
(b) Does the point (16, -1) lie on this circle. Show why or why not

Step-by-step explanation:

x² + 12x + y² - 8y = 73

(x² + 12x + 36) + (y² - 8y + 16) = 73 + 36 + 16

(x + 6)² + (y - 4)² = 125.

Hence the coordinates of the center is (-6, 4).

Since (16 + 6)² + (-1 - 4)² = 22² + (-5)² = 509 and 509 is not equal to 125, (16, -1) does not lie on the circle.

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
