Week 2 Review Assignment - 2
I pledge to support the Honor System of ECPI. I will refrain from any form of academic dishonesty or deception, such as cheating or plagiarism. I am aware that as a member of the academic community, it is my responsibility to turn in all suspected violators of the honor code.
I understand that any failure on my part to support the Honor System will be turned over to a Judicial Review Board for determination. I will report to the Judicial Review Board hearing if summoned.

Review Assignment Problems
NOTE: Handwritten work is not acceptable. All work must be typed and submitted on a Word Document.
a. Identify and list all variables from the problem.
. Write the equation(s) you will use that are found in the textbook. Do not use any other equations.
c. Substitute your variables into the equation. YOU MUST INCLUDE UNITS IN ALL PLACES OF YOUR EQUATIONS.
d. You must show all of your work, even “simple” calculations. During your calculations, please use 3 decimal places or 3 significant decimal places. This does not apply to financial cost calculations.
e. Clearly identify your answer with co
ect units.
