Question 969592
.
Given two points ({{{x[1]}}},{{{y[1]}}}) and ({{{x[2]}}},{{{y[2]}}}) 
Let d=distance between the points:
.
{{{d=sqrt((x[2]-x[1])^2+(y[2]-y[1])^2)}}}
.
For given points (3,12) and (-4,3):
.
{{{d=sqrt((-4-3)^2+(3-12)^2)}}}={{{sqrt((-7)^2+(-9)^2)=sqrt(49+81)}}}={{{sqrt(130)=11.40}}}
.
ANSWER: The distance between the points is 11.40.
