To answer this question we will use the following formula for the vector dot product:
[tex]u\cdot v=||u||||v||\cos\theta.[/tex]
Substituting the given information we get:
[tex]u\cdot v=24*4\cos150º.[/tex]
Simplifying the above result we get:
[tex]u\cdot v=96cos150º\approx-83.1384.[/tex]
Answer:
[tex]-83.1384.[/tex]
