The profit of a firm depends on three positive input factors and as follows:
Determine input factors which maximise the profit function and find the maximum profit. For simplicity please round to 2 decimal places.
The firm AC/DC Associates manufactures ballet tutus and tights, and is in intense competition with Bob Dylan Co. and Queen Plc. All three companies are competing fiercely over the quality of their tutus and tights, and this has been a challenge recently. Ballet companies have been switching between the three companies in pursuit of finding the best tutus and tights for their dancers. Last season, the Gaga Ballet Company purchased items from all three companies as follows:
Table 1. Gaga Ballet Company's Purchases
The cost of these items are given in the following chart:
Table 2: Cost of items
Let Q be the 2x3 matrix corresponding to the purchases, and let C be the 2x3 matrix corresponding to the costs per item.
Compute the product CTQ. What do the diagonal entries of the product represent?
Diagonal entries: Total Cost to Ballet Company, broken down by company
Diagonal entries: Total Cost to Ballet Company, broken down by item
Find the solution vector of the following linear system
3x1 + 2x2 - 2x3 = 1
2x1 - x2 + x3 = 3
x1 + 3x2 - 2x3 = 1
Find the solution for the differential equation dy/dx + 7x = 0 given y(0)=3. Evaluate this answer for x=1.
(This one is harder, so don’t worry if you find this one too difficult)
Let p denote the probability that a firm fiddles its books. Suppose that p = 0.1 . Also suppose that a financial professional services firm keeps auditing firms until they have found 3 ‘bad’ ones.
Compute the probability that they will need to audit exactly 6 firms.
