Question

Given that x=<4,1,5> and y=<11,2,-6> find x•y

Answer 1

Answer: 12

==============================

Step-by-step explanation:

Multiply the corresponding coordinates of the vectors

4*11 = 44

1*2 = 2

5*(-6) = -30

Then add up the results: 44+2+(-30) = 42-30 = 12

The dot product of two vectors is always a scalar value.
