The Answer is "A" (only). Is
there a smart way to find that only A is the correct answer without
having to go through testing all the given options? That is my
question. Rest all I know how to do them. Just please help me find
a smarter way.

Is there a way to view only the answer to a problem and not the solution? When I am doing my work I would like to check just my answer without seeing the solution to the answer. Sometimes I will see parts of the solution that I may not have considered and then I feel like it has ruined the process of me trying to figure out the answer on the own. So is there a way to view only...

Hello,
I would like to discuss with someone the work that i've done
on my own regarding part d).
So we have d unique eigenvalues and d < n. if d=n, then we
only have a trivial solution (by the rank nullity theorem), but
this is a contradiction because v is a non-zero eigen vector.
hence the determinant (A- \lambda*I) =0. where this determinant
is equal to the characteristic polynomial equation.
The polynomial equation p(A)= \prod (A- \lambda_i * I)...

Domestic violence is characterized by the complexity of the relationships and actions of the perpetrator who gradually creates an environment where he/she can perform violence and terrorize his/her victims, while on the other hand it is getting increasingly harder for the victim to find a way out of the abusive relationship. This is Esi's story: “When I first saw him, I thought I met the man of my dreams. He was really charming and wanted to be with me all...
