find the distance between points m(-4,6) and n(10,-5). round to the nearest tenth if necessary.

Sagot :

use the distance forumla
d=[tex] \sqrt{(x1-x2)^2+(y1-y2)^2} [/tex]
subsitute
x1=-4
x2=10
y1=6
y2=-5

d=[tex] \sqrt{(-4-10)^2+(6-(-5))^2} [/tex]

d=[tex] \sqrt{(-14)^2+(6+5))^2} [/tex]

d=[tex] \sqrt{(-14)^2+(11))^2} [/tex]

d=[tex] \sqrt{196+121} [/tex]

d=[tex] \sqrt{317} [/tex]
d=aprox 17.8045
if on a test, put √317
