Answer:
They are orthogonal.
Step-by-step explanation:
u = <3, 0> v = <0, -6>
u.v =|u| |v|cosθ
if u.v is 0 this means that cos θ is 0 so θ = 90°
[tex]\theta=cos^{-1}\frac{u.v}{|u|\ |v|}[/tex]
If u.v = 0 then they are orthogonal.
If u.v ≠ 0 then they are neither parallel nor orthogonal
If u.v ≠ 0 and u = kv where k is constant then they are parallel
u.v = 3×0+0×-6
⇒u.v = 0
They are orthogonal.
