Let U = {1, 2, 3} and A, B and C be subsets of U. The statement C + A = (A – B) + C is NOT an identity.

Which one of the following alternatives contains sets A, B and C that can be used as counterexample to prove that the given statement not an identity.

•  A. A = {1}, B = {2}, C = {3}
•  B. A = {1}, B = {3}, C = {1, 2}
•  C. A = {1, 2}, B = {2, 3}, C = {1, 2}
•  D. A = {1}, B = { }, C = {3}

Suppose U = {1, {2, 3}, 3, d, {d, e}, e} is a universal set with the following subsets:

A = {{2, 3}, 3, {d, e}}, B = {1, {2, 3}, d, e} and C = {1, 3, d, e}.

Let S = {(1, 3), (1, d), (1, e), (d, e), (3, d)} be a relation on set C.

Which one of the following statements regarding S is true?

•  A. S is a strict total order.
•  B. If (e, 3) is added to S, it would make S transitive.
•  C. If (e, 3) is added to S, S would satisfy trichotomy.
•  D. S is a weak partial order

• Suppose U = {b, {c, 3}, 3, 4, {4, 5}, 5} is a universal set with the following subsets: A = {{c, 3}, 3, {4, 5}}, B = {b, {c, 3}, 4, 5} and C = {b, 3, 4, 5}. Let S = {(b, 3), (b, 4), (b, 5), (4, 5), (3, 4)} be a relation on set C. Which one of the following statements regarding S is true? 
• A. If (5, 3) is added to S, S would satisfy trichotomy.
•  B. S is a strict total order.
•  C. S is a weak partial order.
•  D. If (5, 3) is added to S, it would make S transitive.

Consider a plane represented by the equation 11x+8y+6z+83=0. Find the distance of

this plane from origin. After that find the distance of this plane from a point P(6, 3, 3).

Consider a vector in 2D. The vector is represented by v(34, 25). If the vector is rotated

counterclockwise by an angle of 70 degree, what will be the rotated vector? Clearly

show your calculation.

Consider two lines L1 and L2. The parametric form for L1 is P1(3, 6, 9), V1(6, 9, 12).

The parametric form for L2 is P2(1, 4, 7), V2(11, 6, 12). Determine if the lines

intersect each other. If the lines intersect, find the intersecting point. If they do not

intersect, write how you deduced that.

1.)  Establish the initial feasible solutions of the LP model using NCR (North west Corner Rule), MCM ( Minimum Cost Method or Greedy Method), and VAM ( Vogel’s Approximation Method)

 Minimize: C = 14X_1A + 25X_1B + 13X_1C + 18 X_1D.+ 10X_2A + 12X_2B + 13X_2C + 11X_2D + 15X_3A + 20X_3B + 11X_3C+ 25X₃

   Subject to:  X_1A + X_1B + X_1C + X_1D = 140   X_1A + X_2A + X_3A = 100

                      X_2A + X_2B + X_2C + X_2D = 160   X_1B + X_2B + X_3B = 100

                      X_3A + X_3B + X_3C + X_3D = 50     X_1C + X_2C + X_3C = 50

                      X_1D + X_2D + X_3D = 100 X_ij
