Question

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

Answer 1

`r=5√(5)`

Explanation:

we are given as

(x, y), = (5, 10)

we can compare

x-value is 5

`x=5`

y-value is 10

`y=10`

now, we can use formula

`r=√(x^2+y^2)`

now, we can plug values

`r=√(5^2+10^2)`

`r=√(25+100)`

`r=√(125)`

so, we get

`r=5√(5)`
