Find the distance from M to L. 16 34 8

OpenStudy (melody323):

16 square root 34 34 square root 17 8

OpenStudy (melody323):

Somebody help please!!

OpenStudy (mathwizzard3):

What do you think you should do?

OpenStudy (mathwizzard3):

To find the distance

OpenStudy (melody323):

I don't know

OpenStudy (mathwizzard3):

I would say the distance formula. By any chance to you know what the formula is?

OpenStudy (melody323):

No sorry

OpenStudy (mathwizzard3):

Distance = \[\sqrt{ (x (two) - x (one))^2 + (y(two) - y (one))^2 }\]

OpenStudy (mathwizzard3):

this means the second x coordinate - the first x coordinate

OpenStudy (melody323):

Oh ok

OpenStudy (melody323):

Can you give me an example?

OpenStudy (melody323):

@rebeccaxhawaii

OpenStudy (mathwizzard3):

lets say we have points (9,7) and (11, 10)

OpenStudy (melody323):

ok

OpenStudy (mathwizzard3):

the second x coordinate would be 11

OpenStudy (mathwizzard3):

the first x coordinate would be 9

OpenStudy (mathwizzard3):

so it would be 11-9

OpenStudy (mathwizzard3):

so why don't we find the coordinates first

OpenStudy (melody323):

For the equation i got (-3,1) (2,2). Which would be ( -3 - 2)

rebeccaxhawaii (rebeccaxhawaii):

plug in your points

OpenStudy (mathwizzard3):

(-3, -1) and (2,2)

OpenStudy (melody323):

oh ok

OpenStudy (mathwizzard3):

so if we plug it in it is the square root of (2 -(-3)^2 + (2-(-1)^2

OpenStudy (mathwizzard3):

so what is 2-(-3)?

OpenStudy (melody323):

5

OpenStudy (mathwizzard3):

yup and what about (2-(-1)

OpenStudy (melody323):

3

OpenStudy (mathwizzard3):

so if we plug it in it is the square root of (5)^2 + (3)^2

OpenStudy (mathwizzard3):

SO if you square them it is 25 + 9

OpenStudy (mathwizzard3):

the square root of 25 + 9

OpenStudy (mathwizzard3):

so the square root of 34 is your answer

OpenStudy (melody323):

ok thanks

OpenStudy (melody323):

Can you help me with another one?

OpenStudy (mathwizzard3):

Sure!

OpenStudy (melody323):

I gonna post up.

OpenStudy (mathwizzard3):

okay
