Question

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

u = <9, 3>, v = <36, 12>

Answer 1

take the dot product and see what you get

Answer 2

certainly dot product cant be zero since all coordinates are positive

Answer 3

however you do see that v = 4u

Answer 4

so what does that tell you

Answer 5

i put neither

Answer 6

since v = 4u they are parallel

Answer 7

thankyou

Answer 8

@kanwar245 can you help me? same question but with these variables u=<-1,3>, v=<-9,-3>
