Question

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

u = <10, 0>, v = <0, -9>
will give medals

Answer 1

Have you computed the dot product?

Answer 2

If the dot product is 0 then u and v are orthogonal
if you don't get 0 you have more work to determine if they are parallel or not...
they are parallel if the angle between them is either 0 degrees or 180 degrees

Answer 3

how do you get the dot product?

Answer 4

\[<a,b> \cdot <c,d>=a \times c+b \times d\]

Answer 5

so its 0

Answer 6

yes
10(0)+0(-9)
is
0+0
which is 0

Answer 7

any questions on this question before I go

Answer 8

ohh okay thank you soo much no questions

Answer 9

k cool
