Question

What is the approximate distance from (2, 5) to (-2, 1)?

Answer 1

subtract the points; square them, add them; then sqrt them

Answer 2

\[\sqrt{(2+2)^2+(5-1)^2}\]

Answer 3

(2, 5)
-(-2, 1)
--------
(4, 4)^2 = (16+16) = 32

sqrt(32) = sqrt(16*2) = 4 sqrt(2)

Answer 4

sqrt(1), sqrt(2), sqrt(3), sqrt(4)
1 ** 2

sqrt(2) is closer to 1 so id say its a little bigger than 4

Answer 5

So 5.65?

Answer 6

yep

Answer 7

use the distance formula!\[D=\sqrt{(X _{1}-X _{2})+(Y _{1}-Y _{2}})\]

Answer 8

the distance formula still has to be stepped thru; which is why i just go to the steps :)
