Write a particular specification for a cut-to-fill earthworks operation for a large sports
field. Use the SABS 1200 format. You will have to establish realistic values for the
density requirement of the fill, quality requirements and tolerances, method of payment
and sufficient pay items. Use SABS 1200 DA as a guide.
Assume that the ground conditions are unknown and could include rock, hard and soft
materials. Also assume that the size of the sports field is not known as the Client has
not yet decided if he needs a field for soccer, rugby, cricket or hockey, or all four. Note

A council health inspector threatens to close down a restaurant by issuing a fake health violation
notice if the owner does not make a financial payment to him. If the restaurant owner does not
cooperate, the restaurant cannot be opened for business and the negative publicity will drive
customers away. Faced with the potential economic loss, the owner makes the payment.

When should S&H recognize the revenue and the expense? How much expense should be recognized? S&H Green Stamps In the 1950’s and 1960’s supermarkets gave customers “green stamps” for every dollar of purchases at the grocery store. These stamps could then be redeemed by the customers for merchandise at an S&H warehouse. Basically, the company (Sperry and Hutchinson) provided the stamps to the grocers who didn’t have to pay for the stamps until the month after they were given out to customers. Unused stamps could be returned to the supplier. The customer would collect the stamps in a book until enough stamps had accumulated. The customer would then visit S&H’s warehouse and redeem merchandise (e.g.. a TV, a basketball, a set of kitchen towels) for a specified number of filled stamp books.
Research Presentation/Poster 20% 22/9
The research presentation will be in the form of an academic conference presentation using Ms
PowerPoint or a poster. Students will provide an overview of their research, and each student will
present to their learning circle/peers in class. The presentation should be about 3 mins, and there
should be about 7 slides that explain the different stages of your research. Present succinct
information. You need to upload the file with the powerpoint/poster, and insert slide number.
1. Your research aims and justification of the research
Clearly state the overall aim of the research, with your specific questions/objectives. What
important issue the study aims to solve/understand? What is the motivation for this research?
Why should we care? What is the research gap you are hoping to fill? What is the
value/contribution of your research?
2. Literature review
Briefly tell us what other studies or writers had to say about your research. Tell us what is already
known about your research topic.
3. Methodology/?Paradigm/Methods
Explain the research approach and the data collection methods you adopted. You need to explain
the theoretical framework that guides your approach to data collection. What data was collected?
Why this data was collected? How did you collect this data? How was the data analysed? How
reliable/valid/trustworthy are your results? Explain any ethical issues and/or ethics you obtained.
4. Results/Findings
Describe your findings in simple clear words. Focus on the important findings only. Begin with the
main findings and proceed to the minor findings. Make sure that the results provide answers to all
the research questions/objectives.
5. Discussion
Analyse and interpret the results. Explain why your findings important, and how they contribute to
new knowledge. Explain how your findings relate to the findings of other studies in this field.
[You may find that in your discipline, Results/Findings and Discussion are combined, not
separate.]
6. Conclusions
What conclusion/s do you draw from your investigation? What implication does this study have
for practice or theory?
7. References
Use either APA or Harvard styles for referencing. Reference only information that was presented
in your talk. Do not provide the full reference list of your research report. Show appropriate use of
the referencing style that you chose
Learning Circle/Peer Review/Warm and Cool Feedback
You also need to obtain peer review of your research proposal from your learning circle/peer. You
are to use the feedback form provided with Assessment 4, and upload it with this submission.

A metal box with a fixed volume of 8 cubic meters is to be constructed using gold-plating for the top, silver-plating for the bottom, and copper-plating for the sides. Gold plating costs $120 per square meter, silver-plating costs $40 per square meter. and copper-plating costs $10 per square meter. Suppose we want to minimize the total cost of coating such a box.
1) Write the cost function to be minimized. How many input and output variables does the cost function have? (1 point) 2) Are the inputs subject to a constraint equation? If yes, write the constraint equation. (1 point) 3) Use the methods from section 14.7 to find the dimensions of the metal box that minimize the cost of the coating, and then find the minimum cost of coating the metal box. (4 points)
Hint: In order to use the methods of section 14.7, your cost function must have only two input variables. Use the constraint equation to eliminate one of the input variables from the cost function, say z.
4) Use the method of Lagrange Multipliers from section 14.8 to find the dimensions of the metal box that minimize the cost of the coating, and then find the minimum cost of coating the metal box. (4 points)
Verify you get the same answers to #3 and #4.
Hint: To get started with solving the Lagrange System. use the addition/elimination method from algebra to eliminate the terms from the first two equations.
