Question

help please
1. Find the distance between the points (-4, 6) and (8, -12).Round your solution to 2 decimal points.

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

yeah

Answer 3

so plug in values and tell me what u get ?

Answer 4

do u need help with simplification ?

Answer 5

16 n 36

Answer 6

whats that ?
and NO

Answer 7

distance= (-4+8)^2 (6-12)^2 (4)^2 (-6)^2 (16) (36)

Answer 8

there is a -*minus* sign in between
-4-(8) = -12
(-12)^2 = ?

Answer 9

+144

Answer 10

6-(-12) = ?

Answer 11

-6?

Answer 12

6-(-12) = 6+12 = ?

Answer 13

oh 18

Answer 14

now square it

Answer 15

but how do you write this out then? i got it wrong distance= (-4-(8) )^2 (6-12)^2 (-12)^2 (-6)^2 (144) (36)

Answer 16

its 18^2
\(\huge d=\sqrt{(x_1-x_2)^2+(y_1-y_2)^2} \\ \huge \huge d=\sqrt{(12)^2+(18)^2}=?\)

Answer 17

got that ^ ?

Answer 18

144+ 324

Answer 19

yes, then take square root

Answer 20

what u get ?

Answer 21

did u get 21.63 ?

Answer 22

no?

Answer 23

whats 144+324 = ?

Answer 24

its 468 and square root of 468 is 21.63
using calculator......

Answer 25

isnt it 470?

Answer 26

no, 144+324=468
