Homework Statement


Consider the vector V between (-3,-2,-2) and (8,6,9).
What is vector V ?


Isn't this question asking just for the midpoint in that case shouldn't it be <5/2,2,7/2>. Webwork my online homework submitter tells me I'm wrong.

Most likely it is asking for the vector made by the two points.
 
The MIDPOINT between two vectors A and B is (A+B)/2. I think the 'between' in this problem means the vector that joins the two points A and B. That would be B-A. Your confusion about the word 'between' is understandable.

Yes, you are right thank you.
