Question

Find the distance between (–2, –3) and (–6, –12). Round the answer to the nearest hundredth, if necessary.
a.
9.85 units
c.
13 units
b.
7.26 units
d.
17.49 units

Answer 1

Distance between points (x1,y1) and (x2,y2) is
\(\huge d=\sqrt{(x_1-x_2)^2+(y_1-y_2)^2}\)
does this help ??

Answer 2

omg do you have that pre-copied or something lol no way you typed it that fast

Answer 3

@Mew did u get you r distance ?

Answer 4

do you know what to do?

Answer 5

@Mew i assume you are trying ..... are u stuck ?

Answer 6

I'm trying. My teacher is lecturing so I can't use the computer when he is.

Answer 7

I only have a crappy calculator to use. :I

Answer 8

-2-(-6)=?

Answer 9

theres a way to see if you can do this with as minimal calculations as possible

Answer 10

subtract one point from the other

(–2, –3) and (–6, –12)
+6+12 +6+12
------- -------
4 , 9 0 , 0

this, in effect, moves it to the origin so that you can read off the leg values

Answer 11

now, by properties of right triangles; the length of the missing side is longer than the logest leg; but shorter than the sum of the legs

are there any values bigger than 9
but less than 9+4

Answer 12

Ah, thank you. :) Much easier.

Answer 13

as long as only one of the choices fits, that is a pretty simple way to go; and its a good way to narrow down the field :) youre welocme
