Question

Find the distance between points P(8,2) and Q(3, 8 ) to the nearest tenth

Answer 1

7.8 units

Explanation:

We have the following points:

`\begin{gathered} P(8,2) \\ Q(3,8) \end{gathered}`

In this case, we must apply the following formula to calculate the distance between both points:

`d=\sqrt[]{(x_2-x_1)^2+(y_2-y_1)^2}`

replacing:

`\begin{gathered} d=\sqrt[]{(3-8)^2+(8-2_{})^2} \\ d=\sqrt[]{(-5)^2+(6_{})^2} \\ d=\sqrt[]{25+36} \\ d=\sqrt[]{61} \\ d=7.8 \end{gathered}`

The distance between both points is 7.8 units
