Question

Find the distance between the two points. Round to the nearest tenth if necessary.

(8, 8), (12, 11) (1 point)

7
5
25
28

Answer 1

do you know the distance formula?

Answer 2

nope.

Answer 3

mathlife, I see that you are learning about the pythagorean theorem right now.

Answer 4

Instead of closing and opening new questions, do you want someone to explain it to you? It will make your test questions much easier, we promise you.

Answer 5

yes & i really neeed to pass this.

Answer 6

Well, even if you pass this now, it will come back and bite you for the unit exam. Safest way is just to learn the theorem; trust me, it is not that hard.

Answer 7

okay

Answer 8

Since I have to go to bed, I'll just attempt to fetch the best users :)

Answer 10

can somone help me?

Answer 11

???

Answer 12

They are here, let them type :P

Answer 13

Do you know what does this numbers (8, 8) , (12, 11) are about?

Answer 14

no

Answer 15

They are called cartesian-coordinates. It's one of the cutest thing of mathematics. French mathematician René Descartes introduced this idea.

I called it cute because it introduces relationship between planer geometry and algebra like putting numbers to abstract stuffs.

Read a little about it from here: http://en.wikipedia.org/wiki/Cartesian_coordinate_system

Answer 16

The problem you are doing is to find the distance between any two points in this system.
