Question

Find the distance between the points R(0, 5), S(12, 3) to the nearest tenth.

Answer 1

x distance is 12 - 0 = 12
y distance is 3 - 5 = -2
Using Pythagorean's Theorem,
12^2 + (-2)^2 = c^2
144 + 4 = c^2
c^2 = 148
c = 12.1655
c = 12.2
where c is the length of a straight line connecting the two points.
