`{:(0.2u +0.3 v =1.3),(0.4u+0.5v=2.3):}`

Solve :3(2u+v)=7u v , 3(u+3v)=11 u v

2u+3v=2,4u-6v=0 then v=……..

2u+3v=2,4u-6v=0 the value of u= ……….

If 3u + 4v =10 nd S_u = 1.2 . then Var (v) = 0.81

The component forms of vectors u and v are given by u = u = (:5,3:) and v = (:2,-7:) . Given that 2u + (-3v) + w = 0 , what is the component form of w?

Let u,v and w be vectors such that u + v + w = 0. If |u| = 3, |v| = 4 and |w| = 5, then uv.vw.wu is equal to

Let A = [(1,0,0), (2,1,0), (3,2,1)], and U_1, U_2 and U_3 are columns of a 3 xx 3 matrix U . If column matrices U_1, U_2 and U_3 satisfy AU_1 = [(1),(0),(0)], AU_2 = [(2),(3),(0)], AU_3 = [(2),(3),(1)] then the sum of the elements of the matrix U^(-1) is
