points. Check to see if any pages are missing. Enter all requested information on the top of this
page.
You may
not
use your books, notes, or any calculator on this exam. You may not receive any assis-
tance with the exam or communicate with others (other than your professor) about the problems

Do not cut apart, tear apart, or in any other way remove any
pages from this exam packet.

lems.

tially correct calculations and explanations might still receive partial
credit.

corre-
sponding to your final answer.
Do not select multiple answers.
