Question

find the distance between the points to the nearest hundredth! Will give medal and become fan! (: help plz

Answer 1

lol :P

Answer 2

from -3 to 4 is 7 units
from -10 to 9 is 19 units
by pythagoras your distance is
\[\sqrt{7^2+19^2}\]

Answer 4

do u know the distance formula?

Answer 5

distance= sq root x2 - x1 + y2 - y1 sq.

Answer 6

sorta correct
d=square root((x2-x1)^2+(y2-y1)^2)

Answer 7

remember the brackets and the individual squares

Answer 8

I got sq root 7sq + 19 sq as my answer!

Answer 9

now evaluate that

Answer 10

are you okay?
you should leave your answer in sqrt form if it doesn't ask you to do it to the nearest tenth or so.

Answer 11

yeah! sorry I was busy so I got 49 and and 361 @Chelsea04

Answer 12

yea, then add them together to get...
under the sqrt sign

Answer 13

I got 410 then do you sq rt that?

Answer 14

if you want to, but I don't think you need to

Answer 15

oh okay thank you! What about this one?

Answer 16

They want it to the nearest hundredth, so you have to take the square root of 410

Answer 17

okay!

Answer 18

where does it say that?

Answer 19

oops, nevermind

Answer 20

sorry its so blurry!

Answer 21

i got 20.25 for the other one when i sqrt 410(:

Answer 22

good, 20.25 is correct

and for the next one, use the same formula and keep in mind that the origin is the point (0,0)

Answer 23

okay so I do 14sq. + 11sq. ?

Answer 24

good, add up the two squares of 14 and 11 to get ???

Answer 25

25! :)

Answer 26

no you square first, then add

Answer 27

14^2 + 11^2

?? + ??

???

Answer 28

remember the sqrt sign at the end

Answer 29

317

Answer 30

17.80

Answer 31

then at the end, like Chelsea04 is saying you take the square root of 317 to get your answer

Answer 32

yep you got it

Answer 33

yup!!! correct!

Answer 34

Thank you!!
