Find the length of the vector. v = (5, 0, 3, -2) %3D ||v|| = %3D

v= Express the vector v x+ 6 -24 y. as a linear combination of G and y PE -5 3

Is Vector Y in the Column space of A? What is the solution set? Write y as an appropriate linear combination. 8 1 9 a = (-5 9 -1 Y= %3D 10 8

Use the figure to sketch a graph of the specified vector. u+2v

Express the indicated vector w as a linear combination of the given vectors v1 and v2 if this is possible. If​ not, show that it is impossible. w= (-1,0,7), V1= (7,6,5), v2=(6,5,3) Select the correct answer​ below, and fill in the answer​box(es) to complete your choice. A.It is possible to express the vector w in terms of v1 and v2​, as w=(___)v1+(___)v2. ​(Type integers or​ fractions.) B.It is impossible to express the vector w in terms of v1 and v2​, because an echelon form of the augmented matrix [v1  v2  w]​, E=___?​, shows that the system is inconsistent.
