Question

Pls help me solve, thanks

Find the distance d(P1 and P2) between the points P1 and P2
P1 = (-2, 5) P2 = (1,4)

Answer 1

\[d=\sqrt{(x2-x1)^2+(y2-y1)^2}\]

Answer 2

Thanks. Not good at square roots but this will do. Thanks

Answer 3

is the ans the square root of -5?

Answer 4

that is 2.24

Answer 5

I got \[\sqrt{10}\]

Answer 6

uhmm will try it again but thanks.

Answer 7

1-(-2) = 3; 3^2 = 9

4-5 = -; -1^2 = 1

sqrt(9+1) = sqrt(10)

Answer 8

*4-5= -1

Answer 9

Lets say you use 2 as x2 and 1 as x1...the same for the y's.

(You should get the same thing)

Answer 10

ok.... trying again

Answer 11

-2-1 = -3; -3^2 = 9

5-4 =1 1^2= 1

sqrt(9+1) = sqrt(10)

You should get sqrt(10) either way

Answer 12

Don't sqaure right away, do subtraction first

Answer 13

I did this time thanks!!

Answer 14

got it. :)

Answer 15

I think you were doing sqrt(1- (-2)^2); resulting in sqrt(1-4) instead of sqrt(-3^2)

Answer 16

that was what i did. you are right
