Use the distance formula to find the distance between the following points. Show all your work. Round to the hundredths place.

(4,5) and (7,3)

(2.4,8) and 1,6.3)

(29,4.1) and (53.2, 100)

Here is some tutoring.

Now, I will do second one.

Let the first point be point1, and the second point2. It doesn't really matter which is which.

distance=sqrt ( (x2-x1)^2 + (y2-y1)^2 )
= sqrt ( (1-2.4)^2 + (6.3-8)^2 )
= sqrt ( (-1.4)^2 + (-1.7)^2)
= sqrt ( 1.96 +2.89)
= sqrt (4.85)
=2.20
