Question

the endpoints of ST are S (-3,2) and T (5,8) find the length of ST

how do i do this?

jim_thompson5910 · Answer

Use the distance formula to find the distance between S and T

anonymous · Answer

well i tried doing that and i got =100 then the square root of 10 but i didnt know if it was right or wrong

jim_thompson5910 · Answer

Remember the distance formula is 

$$\Large d = \sqrt{\left(x_{2}-x_{1}\right)^2+\left(y_{2}-y_{1}\right)^2}$$

jim_thompson5910 · Answer

ok let me check

jim_thompson5910 · Answer

yep I'm getting 10 as well, nice job

jim_thompson5910 · Answer

the distance between S and T is 10 units

so ST is a segment that is 10 units long

anonymous · Answer

so its not supposed to be like cordinates? its just the square root of it? i was confused lol

jim_thompson5910 · Answer

well you plug the coordinates in to get sqrt(100) = 10

jim_thompson5910 · Answer

if that's what you're asking about

anonymous · Answer

so the answer is just 10 segments?

jim_thompson5910 · Answer

10 units yes
