-3 0 n(-2, -1) and D: 4 What is D.n? Enter your answer as a vector by filling in the boxes.

Determine whether each vector is a scalar multiple of z=(3,2,5). a v=(92,3,152) b w=(9,6,15)

2. If , and the vector is drawn with its tail at the point, find the coordinates of the point at the head of .

For the vector v=(1,2,2), sketch (a) 2v, (b) v and (c) 12v.
