Assignment Brief and Guidance
Suppose that you work for a company which operates in multidisciplinary streams such as hardware & software development, sales, networking, resources management etc. you have been recruited by the company and it is required for you to work in all the disciplines during the first year probationary period, in order to gain minimum competence in each area. Following tasks asses your mathematics knowledge, skills and its application in relevant areas of work that you are about to get involved.
Task 1
a) Programmes A, B &C, give out notifications every 3 days, every 4 days & every 6 days. when will they give out notifications at the same time during the course of two month
b) Computer store A sells a package of 12 CPU’s for half price while Computer store B sells a package of 9 Desktop monitors for half price. Suppose that you intend to buy CPU’s and monitors to set up a gaming zone and find What is the least number of CPU’s and
Desktop monitors you need to buy in order to make sure you are not left with a surplus
c) A teacher has three computer science classes. Each class has 120, 72, and 184 students respectively. He wants to divide each class into groups (members should be from the same class) In order to give a common assignment so that every group in every class has the same number of students. For the convenience of marking, the teacher expect to set up less number of groups as possible. Find the number of students can put into each group.
d) Suppose you have two hard disks with different disk space’s 512GB and 604 GB. If you are required to partition both disks into equal capacity that are as large as possible, find the space should be allocated for the each partition?
e) Describe importance of prime numbers in detail within the field of computing.

g) A hash function will be used in directing users to servers whereas the modular value of the output will be used in determining the relevant server. Based on the number calculated in previous task ( i.e. modular value 1 directed to server 1).given below are some of the outputs of hash function and determine which server they are belong to
i. 2048
ii. 3987
iii. 2675
h) Find the multiplicative inverse of 2675modn whereas “n” is the number of servers
Task 3
a) Plot following points Cartesian coordinates and enclose it to make a polygon ABCDEA such as A(0,2) ; B(4,8); C(15,5); D(12,4) ;E(6,2)
i. Find the length of the line AC without using the diagram
ii. Find the area of the polygon without using the diagram
iii. Convert the given coordinates to polar coordinates
b) Draw a view port P(0,0) ,Q(0,10),R(16,10),s (16,0) and assume it as the output screen of the computer zoomed at 100 %.Suppose that you have zoomed out to 40% keeping the same aspect ratio ,redraw the image that can be visualized in the screen and also define the new boundaries of the viewport.
Task 4
a) You have been asked to analyse a motherboard to assess the lifespan of the capacitors. When a charged capacitor is connected to a resistor to form an RC (resistor-capacitor) circuit, the capacitor discharge follows the equation:
. -
( ) =
Where is the voltage, is the time in seconds, and is the initial voltage which is equal to 2V.
