I need CORRECT answers to these 20 calculus problems with ALL WOR

I need CORRECT answers to these 20 calculus problems with ALL WORK SHOWN, and steps explained when necesssary. I also need all answers CIRCLED. If 90%+ of answers are correct, all work/steps are shown, and all answers are circled, I will give a great rating, and hire you to make me a study guide for $80 on Mondaay of next week. DO NOT make an offer to do this homework if you are not a calculus expert. LOOK at the 20 attached problems before offering a handshake. I need to get an A on this homework, and am giving plenty of time to get me the answers, so I need them to be correct.   Thanks.
