Answer 2

Hi. To begin. Do you know the distance formula?

Answer 3

d=v x t

Answer 4

Not that one

Answer 5

ok than yes

Answer 6

\[d=\sqrt{(x _{2}-x _{1})^{2}+(y _{2}-y _{1}^{2})}\]

Answer 7

d= (x-x2)^2....

Answer 8

yes that one

Answer 9

Alright so have you graphed your points or no?

Answer 10

yes

Answer 11

Okay so start at the point closest to the origin and what you do is you plug in the points going clockwise in the formula. I'll do the first one for you and then see if you can do the others.

Answer 12

ok thanks

Answer 13

i got 36 for the 1st one

Answer 14

well i got 6

Answer 15

\[d=\sqrt{(7-1)^{2} + (3-3)^{2}}\]
\[d= \sqrt{(6)^{2}+(0^{2})}\]
\[[d= \sqrt{36+0} \]
\[d=6\]

Answer 16

then for the 2nd one i got 3
