Module 3: Critical Thinking

Critical Thinking Assignment (85 Points)

Choose one of the following two assignments to complete this week. Do
not do both assignments. Identify your assignment choice in the title
of your submission.

Option #1: Fencing a Farmer’s Field

As a farmer, suppose you want to fence off a rectangular field that
borders a river. You wish to find out the dimensions of the field that
occupies the largest area, if you have 1500 feet of fencing. Remember
that a square maximizes area, so use a square in your work.

Draw several diagrams to express the situation and calculate the
area for each configuration, then estimate the dimension of largest
possible field.
Find the function that models the area in terms of one of its sides.
Find the point that maximizes the function you found in the second bulleted item.
Calculate the area of the field at the point you found in the third
bulleted item, and then compare your results with the results in the
first bulleted item.

Requirements:

Paper must be written in 3^rd person.
Your paper should be 4-5 pages in length (counting the title page
and references page) and cite and integrate at least one credible
outside source. The CSU-Global Library (Links to an external site.) is a great place to find resources. Your textbook is a credible resource.
Include a title page, introduction, body, conclusion, and a reference page.
The introduction should describe or summarize the topic or problem.
It might discuss the importance of the topic or how it affects you or
society as a whole, or it might discuss or describe the unique
terminology associated with the topic.
The body of your paper should answer the questions posed in the
problem. Explain how you approached and answered the question or solved
the problem, and, for each question, show all steps involved. Be sure
this is in paragraph format, not numbered answers like a homework
assignment.
The conclusion should summarize your thoughts about what you have
determined from the data and your analysis, often with a broader
personal or societal perspective in mind. Nothing new should be
introduced in the conclusion that was not previously discussed in the
body paragraphs.
Include any tables of data or calculations, calculated values,
and/or graphs associated with this problem in the body of your
assignment.
Document formatting, citations, and style should conform to the CSU-Global Virtual Library CSU-Global Guide to Writing and APA: Introduction (Links to an external site.). A short summary containing much that you need to know about paper formatting, citations, and references is contained in the New Sample APA Paper (Links to an external site.). In addition, information in the CSU-Global Virtual Library (Links to an external site.)
under the Writing Center/APA Resources tab has many helpful areas
(Writing Center, Writing Tips, Template & Examples/Papers &
Essays, and others).

Option #2: Cost of Fencing a Garden

As a property owner, you want to fence a garden which is adjacent to a
road. The fencing of the side along the road must be stronger and cost
$5 per foot. The fencing on the other sides cost $3 per foot. The area
of garden is 2000 square feet. Remember that a square maximizes area, so
use a square in your work.

Draw several diagrams to express the situation and calculate the
cost for each configuration, then estimate the dimension of minimum
cost.
Find the function that represents the cost in terms of one of its sides.
Using the graphing utility, graph this cost function.
Find the dimension that minimizes the cost of fencing and compare your results in #1.
