Question

The distance of the point (α, β) from the origin is​

Answer 1

Answer:

Correct option is

D

α

2

+β

2

Let coordinates of point A are A(α,β)

Coordinates of origin are O(0,0)

Thus, by distance formula,

d(OA)=

(α−0)

2

+(β−0)

2

∴d(OA)=

α

2

+β

2

Answer 2

Answer:

The distance of the point (α, β) from the origin is $\sqrt{\alpha ^{2} \:+\:\beta ^{2} }$ .
