Question
Fill in the blank using correct alternative.
Distance of point (–3, 4) from the origin is ______.
Options
7
1
5
−5
Solution
Distance of point (–3, 4) from the origin is 5.
Explanation:
Let the given point be P(–3, 4).
Distance of P(–3, 4) from the origin O(0, 0) is
`sqrt((0 - (-3))^2 + (0 - 4)^2`
= `sqrt(9 + 16)`
= `sqrt(25)`
= 5
