Question

Find the distance d(p1, p2) between the points p1, p2.
p1=(4,-4); p2=(5,1)

Answer 1

Distance between points (x1,y1) and (x2,y2) is
\(\huge d=\sqrt{(x_1-x_2)^2+(y_1-y_2)^2}\)
does this help ??

Answer 2

I got square root of 26 so far.

Answer 3

if I simplify that it goes into 2 * 13?

Answer 4

is 2 square root of 13 the answer?

Answer 5

sqrt 26 is the correct answer
u can't simplify that to 2 square root of 13

Answer 6

I think the formula should be \[\huge d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}\]
or is it the same thing?

Answer 7

same thing

Answer 8

how come this answer I got right it was 2 square root of 17
the problem was p1(4,-3) pr(2,5)

Answer 9

it came out to be square root of 68 that couldn't be simplified right?

Answer 10

yeah, \(\huge \sqrt {68}= \sqrt {4*17}= \sqrt 4 \sqrt 17 =2\sqrt17\)

Answer 11

oh ok I see

Answer 12

thanks

Answer 13

welcomes ^_^
