Question:

Write down a matrix that is not diagonalizable. Explain?

Purna R.

The matrix A =  0 1 0 0  is not diagonalizable. This is because the only eigenvalue of A is 0, but A  0 1  =  0 1 0 0  0 1  =  1 0  6= 0, so the R2 is not spanned by vectors killed by A.

Question:

What does meaning of pressure group?

Purna R.

As name appears we examined it as is. An interest group organized to influence public and especially government policy but not to elect candidates to office. Might new pressure groups emerge that will champion new priorities, such as using the tax code to give working- and lower-middle-income families more of a leg up? A group of people who share an interest, concern, or set of opinions and who try to influence politics or the policies of the government, business, etc.
