Question

In exercises the component form of the vector.
12.)The sum of AB and CD where
A(1,-1)
B(2,0)
C(-1,3)
D(-2,2)

I got <0,4>
Is this the correct answer?

Answer 1

AB=<3,-1>
CD=<-3,5>

So adding i got <0,4>

Answer 2

hmmm does it mean \(\large A\cdot B+C\cdot D?\)

Answer 3

They are vectors

Answer 4

\(A\cdot B\ne A+B\) thus

Answer 5

I could be wrong, but sounds as if it's asking for the "dot product" of AB and the "dot product" of CD
and then their sum

Answer 6

No that's in the next section. This is just asking for the sum of the two vectors giving these two points and i wanted to know if it was right.

Answer 7

hmmm
