write the standard equation below for the circle
answers:
(x + 1)2 + (y - 2)2 = 1
(x - 1)2 + (y - 2)2 = 1
(x + 1)2 + (y + 2)2 = 1
(x - 1)2 + (y - 2)2 = 1

Answer 1

i think its the second one

Answer 2

or is it the first?

Answer 3

well the coordantes for the circle are -2,2

Answer 4

yeah i got that part

Answer 5

and u have to times a negitive and a negitive to make a positive or it HAS to be a positive times a positive = a positive

Answer 6

soo it gives u the answer of....

Answer 7

The circle equation is

(x−h)2+(y−k)2=r²

\[\large (x - h)^2 + (y - k)^2 = r^2\]

Center is (h , k) Radius is r

so your center is plotted at -1 , 2 right?
and the radius is clearly 1

So this is put in as

\[\large (x - (-1))^2 + (y - 2)^2 = 1^2\]

\[\large (x + 1)^2 + (y - 2)^2 = 1\]

Answer 8

show off :P

Answer 9

I try :P

Answer 10

And woo I brought you to a 50 :D

Answer 11

Answer 16

haah yeah the mean in math and of course u are mwahhahah 3:)

Answer 17

lol

The mean *average* is where you take the sum of all the numbers you have...and divide that sum by the number of numbers.

Example.....say you have 3, 5, 7, and 9

You add them all up...3 + 5 + 7 + 9 = 24

And divide that by the number of numbers...there are 4 numbers you added so

24 / 4 = 6...and 6 would be the mean :)
