Answer: C. 13</h3>
===============================================
Explanation:
In general if we have these two vectors
u = (a,b)
v = (c,d)
Then the dot product of them is
u dot v = a*c + b*d
We multiply the corresponding coordinates, then add up the products.
-----------------------
In this case,
u = (3,2)
v = (1,5)
u dot v = 3*1+2*5
u dot v = 3 + 10
u dot v = 13
