1. You are a project manager of a large project scheduled to last for 2 years. 6 teams are working on 5 functional areas. Some are ahead and some are behind schedule. Its 9 months into your project. The total budget is $4,200,000. You’ve spent $1,650,000 so far, and you’ve got a CPI of .875. Use the Earned Value Technique to figure out if the project is over or under budget.
2. In continuation with question 1, Now its 6 months later(9+6 months into the project). You have spent 2,625,000. You have completed 70% of the project. You need to report to the management if you are now over or under budget.
3. Give real life software project examples which are best suited to be developed in the following development methodologies. Also give reason behind your choice. (For example for facebook, agile will be a good choice)

   a) Waterfall

   b) Prototype

   c) V-Model

3. Develop a program to maintain a list of homework assignments. When an assignment is assigned, add it to the list, and when it is completed, remove it. You should keep track of the due date. Your program should provide the following services: • Add a new assignment. • Remove an assignment. • Provide a list of the assignments in the order they were assigned. • Find the assignment(s) with the earliest due date. 4. We can represent a polynomial as an ordered list of terms, where the terms are ordered by their exponents. To add two polynomials, you traverse both lists and examine the two terms at the current iterator position. If the exponent of one is smaller than the exponent of the other, then insert this one into the result and advance that list’s iterator. If the exponents are equal, then create a new term with that exponent and the sum of the coefficients, and advance both iterators. For example: 3x4 + 2x2 + 3x + 7 added to 2x3 + 4x + 5 is 3x4 + 2x3 + 2x2 + 7x + 12 Write a program to read and add polynomials. You should define a class Term that contains the exponent and coefficient. This class should implement operator< by comparing the values of the exponents.

Define a function drawCircle. This function should expect a Turtle object, the coordinates of the circle’s center point, and the circle’s radius as arguments. The function should draw the specified circle. The algorithm should draw the circle’s circumference by turning 3 degrees and moving a given distance 120 times. Calculate the distance moved with the formula 2.0 × π × radius ÷ 120.0.

Define a function main that will draw a circle with the following parameters when the program is run:

• X = 50
• Y = 75
• Radius = 100
