Answer:

< 27, -18, 8>

Step-by-step explanation:

Let v = <3, 3, -8>, w = <9, -6, -1>

v*w = < 3*9, 3*-6, -8*-1>

       < 27, -18, 8>

Answer:

17

Step-by-step explanation:

do (a1 x a2) + (b1 x b2) + (c1 x c2)

(a1 x a2) = 3(9) = 27

(b1 x b2) = 3(-6) = -18

(c1 x c2) = 8

27 + (-18) + 8 = 17

When finding dot product, always add up the results, otherwise it's incomplete!
