@AriPotta

OpenStudy (anonymous):

do you know how to do it?

OpenStudy (aripotta):

by just looking at the graph, you can see the distance between a and d

OpenStudy (aripotta):

however, you can also use the distance formula if you want:\[\sqrt{(x _{2}-x _{1})^2+(y _{2}-y _{1})^2}\]

OpenStudy (anonymous):

dang sorry i copied the wrong question

OpenStudy (anonymous):

ok here let me get the right question up

OpenStudy (anonymous):

OpenStudy (aripotta):

ok, use the distance formula \[\sqrt{(x _{2}-x _{1})^2+(y _{2}-y _{1})^2}\]

OpenStudy (anonymous):

ok

OpenStudy (aripotta):

what do you get?

OpenStudy (anonymous):

\[\sqrt{(2-(-4)^{2}+(-4 -1)^{2}}\]

OpenStudy (anonymous):

like that

OpenStudy (aripotta):

yes. keep working to get the answer

OpenStudy (anonymous):

3.316625

OpenStudy (aripotta):

that's not what i got

OpenStudy (anonymous):

What did you get?

OpenStudy (anonymous):

7.8?

OpenStudy (aripotta):

\[\sqrt{(2-(-4))^2 +(1-(-4))^2}=~ \sqrt{6^2 + 5^2}=~\sqrt{36+25}=~\sqrt{61}=~7.81\]

OpenStudy (aripotta):

yea

OpenStudy (anonymous):

ok thanks
