- 2. If , and the vector is drawn with its tail at the point, find the coordinates of the point at the head of .arrow_forwardTake 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_forwardWhich of the following vectors is parallel to the line 7x+ 14y = 20? %3D (-6,3) (8,-16) (2,4) 0. (10, 5) None of the listed answers.arrow_forward
- 4. a. If 37– 2ỷ = đ and 53 – 3ỷ = b, express the vectors i and y in terms of a and b. %3D b. Solve for a, b, and c: (2, –1, c) + (a, b, 1) – 3(2, a, 4) = (-3, 1, 2c). %3Darrow_forwardif given the equation yi = B0 + B1xi +ui and express the same equation as y = xiB = ui (where xi and B here are vectors), does vector xi = [1 x1] or xi = [x1] (row vector) and B vector (column vector) = [B0; B1]?arrow_forwardPlease make easy to readarrow_forward
