Question 1162174
<br>
The rule about only one question per post means you aren't supposed to post several different problems in one post.  This is the second part of a single problem; posting it by itself makes no sense.<br>
Posting a single problem that contains two questions IS ALLOWED.  I am sorry if you have had the experience of getting responses from tutors at this forum saying otherwise.<br>
I will answer this second part of the problem in my response to your other post.<br>
