Question

What is an expression for the distance between the origin and a point P(x,y)

Answer 1

`d = \sqrt{ {x}^(2) + {y}^(2) }`

Explanation:

Distance between origin (0, 0) and point (x, y) is given as:

`d = \sqrt{ {(x - 0)}^(2) + {(y - 0)}^(2) } \\ \\ \red{ \bold{ d = \sqrt{ {x}^(2) + {y}^(2) } }}`
