Question

Given that (x,y)=(5,10), find r

Answer 1

`r = 5 √(5 )`

Step-by-step explanation

Given that (x,y)=(5,10), we want to find r.

We use the relation:

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

We substitute x=5 and y=10 into the formula to get,

`r = \sqrt{ {5}^(2) + {10}^(2) }`

This implies that,

`r = √( 25+ 100 )`

`r = √(125)`

`r = 5 √(5 )`
