Evaluate the expression. r =, v =, w = v ⋅ w

v ⋅ w = 17

Step-by-step explanation:

We are given that,

v = and w =

It is required to find v ⋅ w.

So, evaluating the expression, we get,

v ⋅ w = ⋅

i. e. v ⋅ w = 3*9 + 3 * (-6) + (-8) * (-1)

i. e. v ⋅ w = 27 - 18 + 8

i. e. v ⋅ w = 35 - 18

i. e. v ⋅ w = 17

Hence, after evaluating, we have, v ⋅ w = 17
