Calculus 3, about 14 general problems, calculus homework help

Asking for help with some fourteen general calculus problems. Attached are the problems, and the textbook I use for class.

I created the attached pdf the problems are listed in. The solutions to the problems should simplify to something fairly simple. If an answer to a problem appears to be something astronomical; it is possible that I might have a typo in the question.

Please list the steps to solving, try help me to understand how to complete these for myself. If there are any issues, I will be be intermittently available for messaging.

I do not expect perfection, but I would like something intelligent as an answer.

If you get part of it done early, I would appreciate parts of it returned early as opposed to all of it at once returned later. But I value quality over speed, so do whatever you need to do to have the highest quality before the deadline.

Thanks! 🙂
