Question

vectors

Answer 1

are the vectors u=<7,-4>, v=<-28,16> parallel, orthogonal, or neither

Answer 2

1_ if u=kv s.t k \(\in R\) then they are parallel
or check using
if u×v=0 then they are parallel

2_if u.v=0 then they are orthogonal

Answer 3

but 7*-28 dosent equal 0 so its orthogonal?

Answer 4

if they are not orthogonal nor parallel then they are neither

Answer 5

wait so its not orthogonal either?
so its neither? .-.

Answer 6

yep :D
