Question

Please help!!!
The equation of Circle P is ( x − 3)2 + (y + 2)2 = 34 and the equation of circle Q is (x − 4)2 + (y + 5)2 = 52. What is the distance between the centers of these circles?

Answer 1

please explain step by step too, im so lost and i need to understand

Answer 2

you know how to find the distance right??

Answer 3

no...im very confused...

Answer 4

if two points are given

Answer 5

i dont remember how..

Answer 6

You need to put the equations of these circles in standard form. Divide the first equation by 34 and the second one by 52. (Also, I LOVE the Hunger Games)

Answer 7

just because u said u love the hunger games...and how do u put it in standard?

Answer 8

they are in standard form

Answer 9

Oh XDD I didn't read the whole question >_< sorry. You can just use the center, its inside the parentheses

Answer 10

if it is in standard form what do you do next?

Answer 11

well tell me if you know this formula

Answer 12

"Circle P is ( x − 3)2 + (y + 2)2 = 34". The center is inside the parentheses so since it says (x - 3) the x-coordinate of the center will be 3 and since it says (y + 2) the y-coordinate of the center will be -2.

Answer 13

As experimentX said, you can then find the center of the other circle and use the distance formula to get the distance between the two points.

Answer 14

oh yes ive seen that formula before....

Answer 15

What's the center of the second circle?
(x − 4)2 + (y + 5)2 = 52.

Answer 16

is it possible for someone to make a visual? Im not really understanding...

Answer 17

yes use this distance formula .. between two points that you can find by reading two posts above.

Answer 18

You want to find the length of that line between the centers there.
