Best ResponseYou've already chosen the best response.0find out the distance between the pair of points. give an exact answer and where appropriate an approximation to there decimal place

Best ResponseYou've already chosen the best response.1you'll need to use the distance formula \[\Large d = \sqrt{\left(x_{2}x_{1}\right)^2+\left(y_{2}y_{1}\right)^2}\]

Best ResponseYou've already chosen the best response.1for (6,1) and (20,35) we see that x1 = 6 y1 = 1 x2 = 20 y2 = 35

Best ResponseYou've already chosen the best response.0yes i know but my answers are off trying to figure out why or how it should look since i can't seems to figure out why

Best ResponseYou've already chosen the best response.1what answer did you get for the first one

Best ResponseYou've already chosen the best response.0the first one I got \[D=\sqrt{2,500}\]

Best ResponseYou've already chosen the best response.0the second i got \[D=\sqrt{1492}\]

Best ResponseYou've already chosen the best response.1the first one is too big

Best ResponseYou've already chosen the best response.1For for (6,1) and (20,35) \[\Large d = \sqrt{\left(x_{2}x_{1}\right)^2+\left(y_{2}y_{1}\right)^2}\] \[\Large d = \sqrt{\left(6(20)\right)^2+\left(135\right)^2}\] \[\Large d = \sqrt{\left(6+20\right)^2+\left(135\right)^2}\] \[\Large d = \sqrt{\left(26\right)^2+\left(34\right)^2}\] \[\Large d = \sqrt{676+1156}\] \[\Large d = \sqrt{1832}\] Now you can simplify the radical to get... \[\Large d = \sqrt{1832}\] \[\Large d = \sqrt{4*458}\] \[\Large d = \sqrt{4}*\sqrt{458}\] \[\Large d = 2\sqrt{458}\]

Best ResponseYou've already chosen the best response.0the book gives us an answer of \[\sqrt{45,6.708}\]

Best ResponseYou've already chosen the best response.1something is odd about that format

Best ResponseYou've already chosen the best response.1are you sure it says that?

Best ResponseYou've already chosen the best response.0question though why do you go the opposite when replacing the formula with the problem. or does it matter. meaning you did X1  X2 and not X2X1
