Find the distance between points M(6,16) and Z(-1, 14) to the nearest tenth. Show steps please.

OpenStudy (anonymous):

do you know the distance formula between two points?

OpenStudy (excalibur0126):

Nope

OpenStudy (en):

to find the distance between two point use the distance formula:\[D=\sqrt{(x _{2}-x _{1})^2+(y _{2}-y _{1})^2}\]

OpenStudy (en):

just substitute your points for example (a,b) are your first coordinates then they will be your \[(x _{1},y _{1})\] (c,d) are your second coordinates they will be your \[(x _{2},y _{2})\]

OpenStudy (excalibur0126):

So (-1-6)^2+(14-16)^2

OpenStudy (excalibur0126):

-7^2+-2^2 or 49+4

OpenStudy (en):

the answer should be \[D=\sqrt{53}\]

OpenStudy (excalibur0126):

Okay I think I get it, thanks :)

7.280109889 in decimal form

jimthompson5910 (jim_thompson5910):

it says `Find the distance ... to the nearest tenth` so you'll have to convert to decimal form and round

OpenStudy (en):

7.280109889 just round this to the nearest tenth , then BOOM .. you're done
