Question

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

Answer 1

`√(p^2+q^2)`

Explanation:

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

`√((x_1-x_2)^2+(y_1-y_2)^2).`

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

`√((p-0)^2+(q-0)^2)=√(p^2+q^2).`
