10. Given vectors ū = [x, y, 5], v = [3, 1, −4], and w = [7,7,7], find x and y such that uxv=w.

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

For the vector v=(3,2), sketch a 4v, b 12v, and c 0v.

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)
