Matrices

1.

The adjoint matrix of

is

NULL NULL NULL

2.

If the rank of the matrix

is 1, than the value of

is

2

4 NULL NULL NULL

3.

The value of

such that

has a non-trivial solution is

-1 1 2 NULL NULL NULL

4.

If

is a matrix and

is a non-singular square submatrix of order

then

Rank of

is

Rank of

is greater than

Rank of

is less than

None of these NULL NULL NULL

5.

From the matrix equation

we can conclude

provided that

is singular

is non-singular

is symmetric

is square NULL NULL NULL

Congratulations
