Question

Find the distance between (1, 1) and (3, 4).

Answer 1

sqrt (x2 - x1)^2 + (y2 - y1)^2

Answer 2

d^2 = (3-1)^2 + (4-1)^2 = 4+9=13

d=sqrt13

Answer 3

this is done using the distance formula...

for any two points (x,y) and (x',y') the distance between them is..

\[\sqrt{(x-x')^{2} + (y-y')^{2}}\]

so here \[^{13}\] should be it.

Answer 4

i mean root of 13, ie \[\sqrt{13}\]
