Question

Determine whether the vectors u and v are parallel, orthogonal, or neither.

u = <10, 0>, v = <0, -9>

Answer 1

check your dot product a x b
if dot product = 0 they are orthogonal
if they are equal they are parallel

u x v = (10)(0) + (0)(9)= 0+0=0

Answer 2

so orthogonal then?

Answer 3

yup

Answer 4

thanks
