Question

What is the approximate distance from (2, 5) to (-2, 1)?

6 units

5 units

4 units

3 units

Answer 1

4 sqrt(2) ; just like last time i believe :)

Answer 2

6 units

Answer 3

\[d=\sqrt{(x2-x1)^2+(y2-y1)^2}\]
\[=\sqrt{(1-5)^2+(-2-2)^2}\]
\[=\sqrt{(-4)^2+(-4)^2}\]
\[=\sqrt{16+16}\]

\[\sqrt{32}=4\sqrt{2}\]
\[=5.656\]
\[=6 units\]
