Question

Answer Check please?Determine whether the vectors u and v are parallel, orthogonal, or neither.

u = <6, 4>, v = <-9, 8>

I got neither

Answer 1

how do you get that?

Answer 2

well, it doesnt equal zero so i know its not orthogonal, but i watched a vide o before and it said if their not multiples its not parallel o,o

Answer 3

i dont know x.x

Answer 4

do the dot product of two vectors for orthogonal test
for parallel condition
u=kv
<6,4>=k<-9,8>
now 6 =-9k
and 4 =8k
no such K possible hence it is not parallel either

Answer 5

so, it is neither? because when i did the dot product i got -18?

Answer 6

Yes!

Answer 7

for parallel condition you can also do cross product test

Answer 8

oh okay thankyou(:
