Given that vectors = (5,-3) and (2,-5) are orthogonal; find the value of 3 0 2 03 O −15 O −3 O 15 O None of the above.

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

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

Take this test to review the material in Chapters 4and Chapters 5. After you are finished, check your work against the answers in the back of the book. Write w=(7,2,4) as a linear combination of the vectors v1, v2 and v3 if possible. v1=(2,1,0), v2=(1,1,0), v3=(0,0,6)
