Question

Evaluate the expression:

v ⋅ w

Given the vectors:

r = (8, 8, -6); v = (3, -8, -3); w = (-4, -2, -6)

Answer 1

vw= 22

Explanation:

To find the dot product of vw, multiply the corresponding numbers and add them.

v= <3, -8, -3> w= <-4, -2, -6>

vw= (3*-4)+(-8*-2)+(-3*-6)

vw= -12+16+18

vw= 4+18

vw= 22
