A.4sqrt17 B.4sqrt101 C.20sqrt3 D.4sqrt3

Question

jim_thompson5910 · Answer

Find the distance from (7, 2) to (-3, 3)

jim_thompson5910 · Answer

Then multiply that distance by 4 to find the perimeter

anonymous · Answer

i got 1/-10 for distance

anonymous · Answer

is that right?

anonymous · Answer

no, it cfant be right...

jim_thompson5910 · Answer

no, the distance has to have a square root in it

anonymous · Answer

well, how do i find that? i'm sorry if i seem a little slow, but i failed a class last year, and now i have to do it over the computer, so i've been through a whole year in about a week

anonymous · Answer

but luckily, im already at 90%(: thats why i ask so many questions, this last workseet has 80 problems on it

jim_thompson5910 · Answer

I'll show you how to find the distance between these two points and hopefully it will be useful for finding the distance between any two points (so I recommend copying this into your notes)


d = sqrt((x2-x1)^2+(y2-y1)^2)

d = sqrt((-3-7)^2+( 3- 2)^2)

d = sqrt((-10)^2+(1)^2)

d = sqrt(100+1)

d = sqrt(101)


So exact distance between the two points is  sqrt(101)  units.

and i dont wanna rush, but i only have half an hour left, and bout 50 questions, so asap please & yeah i've been taking lots of notes..

jim_thompson5910 · Answer

so if the distance is sqrt(101), what's the perimeter?

anonymous · Answer

4sqrt101?

jim_thompson5910 · Answer

you got it
