Consider u=(3,2) v=(1,5) and the angle between the vectors is 45. What is u times v? a. 3
b. 4
c. 13
d.21

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

the answer, i believe is y-8=1(x+4)

okay, what do you want us to do?
