Question

Let u = <-6, 3>, v = <-1, -6>. Find 4u + 2v.

Answer 1

ok so you are going to start by plugging in -6 for u and -1 for v which should get you 4(-6)+2(-1)=-26. then plug in 3 and -6 to get 4(3)+2(-6)=0 then plug in -6 and -6 which gets 4(-6)+2(-6)=-36. finally plug in 3 and -1 to get 4(3)+2(-1)=10

Answer 2

thank you so much! could you help me with a few more?

Answer 3

of course

Answer 4

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

u = <8, 4>, v = <10, 7>

Answer 5

they are orthogonal!

Answer 6
