Question

Find the distance between the points. ​ (p​, q​) and​ (0, 0)

Answer 1

Answer:

$\sqrt{p^2+q^2}$

Step-by-step explanation:

The distance between two points $(x_1,y_1)$ and $(x_2,y_2)$ can be calculated as

$\sqrt{(x_1-x_2)^2+(y_1-y_2)^2}.$

Then the distance between points $(p,q)$ and $(0,0)$ is

$\sqrt{(p-0)^2+(q-0)^2}=\sqrt{p^2+q^2}.$
