Question

what is the distance between the points (21,-30) and (3,8)? if necessary, round your answer to two decimal places

Answer 1

Determine the distance between the points by using the distance formula.

$\begin{gathered} d=\sqrt[]{(3-21)^2+(8-(-30))^2} \\ =\sqrt[]{324+1444} \\ =\sqrt[]{1768} \\ =42.0475 \\ \approx42.05 \end{gathered}$

So the distance between two points is 42.05 units.

Answer: Option B.
