Digital Signal Processing questions

I have 3 questions in DSP. Sort of small exercises. I need someone to solve them for me. I need the solution to be analytical, not just the result, so that i can understand how they are solved.

Attached are the questions. Need the answers for all the 3 questions today. If you can't answer the 3 questions then don't bid. I will pay 10-15$ for the 3 questions depending on the ratings.
