John was given a task to make a rectangular box during his innovation competition. He was given with
the A cm of wire and B cm2 of special paper. He had to use all the wire (for the 12 edges) and paper (for the 6 sides) to make the box. So what will be the maximum volume of that box?

At the inlet of a converging-diverging nozzle, the stagnation pressure is po = 860 kPa and stagnation temperature To = 79 °C. The outlet of the nozzle is connected to a back chamber in which the pressure can be controlled. There is only one normal shock in the nozzle where the area is As = 367 mm- and the static temperature right after the shock is T2 = 57 °C. The area of the nozzle outlet is 1200 mm2. 1. (40 marks) If the shock happens after the throat: a. What are the Mach numbers at the point just after the shock and at the exit? b. What is the mass flow rate of the flow? a. 2. (20 marks) If the flow at the nozzle inlet is subsonic and the shock happens after the throat: Calculate the area of the throat of the nozzle. b. Given that the condition at the nozzle inlet is fixed and the pressure in the back chamber is adjusted to the point that there is no more shock in the nozzle, what are the possible values of Mach number at the nozzle outlet? Explain your answer.

[solved] – Question 80327
In an experiment, the Merge Sort algorithm will be modified into a 3-MergeSort algorithm in the hope of getting a new algorithm that is more efficient. Basically, the modification made is that the input array of length n is no longer split into 2, but into 3, so that each new array created will have a length of n/3. Answer the following questions:
To accommodate the above modification, the Merge function will be changed to a Merge3 function which no longer accepts input in the form of 2 arrays, but 3 arrays (which have been ordered). Consider the implementation of the Merge3 function in the following pseudocode:
function Merge3(array A, array B, array C):
AB = Merge(A, B)
return Merge(AB, C)
* The Merge function called in the Merge3 function above is the same Merge function as the standard Merge Sort algorithm, which accepts 2 sorted arrays as input.
Calculate the time complexity of the Merge3 function! Use Big O notation with m as input, where m is the total sum of the lengths of the arrays A, B, and C!
Calculate the time complexity of the 3-MergeSort algorithm as a whole! Use Big O notation with n as input, where n is the length of the initial input array!
When compared to the time complexity of the standard Merge Sort algorithm, can the 3-MergeSort algorithm be said to be significantly more efficient?
Suppose the 3-MergeSort algorithm created above is run on the following array: [4, 8, 2, 9, 1, 7, 5, 3, 6]. What will the contents of the array look like when the three outermost recursion function calls have finished, but just before the most recent Merge3 function executed?
