Evaluate the expression:

v ⋅ w
given the vectors:
r = < 8, 1, -6> ; v = < 6, 7, -3> ; w = < -7, 5, 2> (2 points)

The dot product will have you multiply the corresponding coordinates and add up the products

v dot w = (6*(-7)) + (7*5) + (-3*2)
v dot w = -42 + 35 - 6
v dot w = -7 - 6
v dot w = -13

-13
