Question 1171542
<br>
Submitting a list of questions like this with no work shown, and with no indication exactly what it is you want help with, suggests to the tutors that you just want us to do your work for you.  That does not work at this forum.<br>
(1) Rule of the forum: ONE problem per post.<br>
(2) Purpose of the forum: HELP students LEARN HOW to work the problems -- not do the work for them.<br>
Re-post the problems separately -- preferably with some indication of what it is you need help with.<br>
