- Consider an mn matrix A and an np matrix B. Show that the row vectors of AB are in the row space of B and the column vectors of AB are in the column space of A.arrow_forwardLet A be an nn matrix in which the entries of each row sum to zero. Find |A|.arrow_forwardDraw the following vectors in standard position in 2 : aa=30bb=23cc=23dd=32arrow_forward
- 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)arrow_forwardFor each of the following pairs of points, draw the vector AB. Then compute and redraw AB as a vector in standard position. (a)A=(1,1),B=(4,2)(b)A=(0,2),B=(2,1)(c)A=(2,32),B=(12,3)(d)A=(13,13),B=(16,12)arrow_forward
