Question

Two points in a rectangular coordinate system have the coordinates (5.0, 2.5) and (−3.5, 5.2), where the units are centimeters. determine the distance between these points.

Answer 1

√((5.0 - (-3.5))² + (2.5 - 5.2)²) =

`\sqrt{ {8.5}^(2) + {( - 2.7)}^(2) } =`

`√(72.25 + 7.29) =`

`√(79.54) =`

`\sqrt{ (7954)/(100) } = ( √(7954) )/(10) = 8.92`

The distance between these points is about 8.92 cm.
