Chapter 4, Problem 9GRFC

To determine

The distance between each pair of points.

Answer to Problem 9GRFC

  $18.02$

Explanation of Solution

Given:

The given points are:

  $\begin{array}{l}R\left(8,0\right)\\ S\left(-9,6\right)\end{array}$

Calculation:

The distance between two points is given by:

  $\begin{array}{l}=\sqrt{{\left(x_2-x_1\right)}^2+{\left(y_2-y_1\right)}^2}\\ =\sqrt{{\left(-9-8\right)}^2+{\left(6-0\right)}^2}\\ =\sqrt{{\left(-17\right)}^2+{\left(6\right)}^2}\\ =\sqrt{289+36}\\ =\sqrt{325}\\ =18.02\end{array}$
