PLS HELP!!! Find the distance between R(–1, 1) and S(–4, –5) to the nearest tenth.
@Vocaloid
\[D = \sqrt (x _{2-} x _{1})^2 + (y _{2} - y _{1})^2\]
uh?
@bm717 what was that?
Ignore her. Do you know how to use the formula?
the distance formula?
Yes
It was a hand spasm I had this problem first ;-;
I tried doing the distance formula, and I came up with the wrong answer
Can you show your setup?
yes, I did (-1-4) to the second power which would be -25
After you take -5 to the second power, the negative sign goes away \[-5^2 = -5 \times -5 = 5 \times 5 = 25\]
then I did (1-(-5))to the second power, which would be 36
then I added 25+36=61
then I did the square root of 61, which is 7.8
I think I see your problem. You need to do x1 - x2 x1 is -1 x2 is -4 -1 - (-4) = -1 + 4 = 3
so, it's 3 +36
Yes
Try that now
so, square root of 39 is 6.2
@Shadow the choices are: 6.7 9.0 15.8 45.0
You forgot to square 3
I gave shadow the answers, please medal me k thanks
@shadow what?
You are supposed to do 3^2 + 6^2 You did 3 + 6^2
so, I should add the square roots of 3 and 6
Do 3^2
so, 6.7
Correct
