5 finance questions, business and finance homework help

i need the questions 1,2,3,4,6, very short answers, and use your words not any outside source. Don’t use very advanced words, keep it simple.

If you could get this book use it but don’t copy from it “Fabozzi, Modigliani, Jones, Foundations of Financial Markets and Institutions, 4th edition”. Let me know if i do have it.
