Question

Help please!

Answer 1

The dot product of two vectors (for example, A and B with their respective x and y coordinates) is:
\[(x _{1}x _{2})+(y _{1}y _{2})\]
For the first part of A, you must multiply the vector ''v'' by itself.
Vector V: (4,4)
Since both x and y coordinate are 4, you plug in 4 for all the variables:
(4)(4) + (4)(4)= 16 + 16 = 32
V times V= 32
Note that this is only the first part of A.

Answer 2

Oh I figured it out, but can help me in another problem?
