Answer 3

using dot product find the angle between the vectors

Answer 4

@imqwerty help plz

Answer 5

please help

Answer 6

\[u \cdot v = 0\] (dot product if it's 0 then it is orthogonal)
\[u \times v = <0,0>\] this implies the vectors are parallel

Answer 7

Do the dot product

Answer 8

\[6*8+(-2)(24) = 0\] yes you're right :)

Answer 9

The same way you did the first question \[v \cdot w = v_1w_1+v_2w_2+v_3w_3\]

Answer 10

\[v = <v_1,v_2,v_3>\]

Answer 11

No, you want v⋅w which gives a scalar

Answer 12

any of this??

Answer 13

@karim728

Answer 14

vectors no sorry refer to @Astrophysics, has more experience with that

Answer 15

\[v.w=(3)(6)+(4)(-9)+(7)(7)=18-36+49=?\]
