Modelling Problem Using Excel

A company that makes bikes wants to maximize profit over the next five months. Materials for each bike costs $600. Both humans and machines are needed to produce each bike. Each human can work on up to 100 bikes per month. Each machine can work up to 200 bikes per month. TetraCon, Inc. has 4 humans and no m


A quarry consists of 8 quarry pits along a 4000 yard north-south section of land. Each pit is 500 yards away from the other. Rock must be removed from some quarry pits and relocated to others quarry pits as listed below. Quarry 1: 0 to 500 yards - 7,000 tons of rock are needed Quarry 2: 500 to 1000 yards - 3,000 to

Checking for Convexity.

Check that the function: f(x1, x2, x3) = (x1)^2 + (x2)^2 + (x3)^2 - x1 - x2 - x3 is convex. Find the extreme values of f under the conditions: (x1)^2 + (x2)^2 = 4, -1 <= x3 <= 1. (x3 goes from -1 to 1)

Linear transformations

See attached file. 1. For each of the following functions decide whether or not the function is a linear transformation.

Minimal polynomial for a linear transformation

Any explanations of the attached definitions is greatly appreciated. Thank you. The definition of the minimal polynomial for the linear transformation.... the relationship between the cosets in G of the stabilizer....

Fields, homomorphisms

Not sure why, but I am having trouble with this one. I'd really appreciate it if someone is willing to help here. Please see the attached file. Thank you

Linear Programming Model for Maximizing Profit of a Production Schedule

Ms. Olsen, a coffee processor, markets three blends of coffee. They are Brand X, Minim and Taster's Reject. Ms. Olsen uses two types of coffee beans, Columbian and Mexican, in her coffee. The following chart lists the compositions of the blends. Blend Columbian Beans Mexican Beans Brand X 80% 20% Minim 50

Linear Transformations, Hilbert Space, Inner Product and Matrix Adjoint

Please see the attached file for the fully formatted problems. Find a 5x5 matrix M>0 such that if and x(t)= then Can we use this definition to find the adjoint of T (T is given at the end)? This part is the additional information to solve the question above; Let V=L2[-1,1] be the Hilbert space of func

Linear Transformations : Hilbert Space and Inner Product

Please see the attached file for the fully formatted problems. Let V=L2[-1,1] be the Hilbert space of functions over the time interval [-1,1] with inner product Let P5 V be the subspace of polynomials of order 4 or less, endowed with the inner product and norm of V, and let , be its natural basis. Define a linear transf

Transformation of State Variables and State-Space Representations

Consider the system . It can be shown that there is other state equation possible for this system. Let us define a new set of state-variables z1 , z2 , z3 by the transformation: Obtain the state-space representation of the system in terms of the new variables. Please see the attached file for the fully formatted problem

Center of Mass of a 3D Pyramid

I need three different algebraic solutions of the center of mass of a square-based pyramid. Finding the center of mass of a square-based 3D pyramid is usually done in calculus, but our professor wants us to work it out in algebra. One hint he gave us (for one way of approaching this problem) is to split the pyramid into small bl

Linear Spaces, Mappings and Dimensional Spaces

1) Show that if dim X = 1 and T belongs to L(X,X), there exists k in K st Tx=kx for all x in X. 2) Let U and V be finite dimensional linear spaces and S belong to L(V,W), T belong to L(U,V). Show that the dimension of the null space of ST is less than or equal to the sum of the dimensions of the null spaces of S and T. 3)

Linear Mappings, Differentiation and Linear Spaces

1) Show that this mapping is linear: T: P5 -> P8 defined as Tp(t)=p(t+1)-p(t)+integral(t-1 to t) s^2 p(s) ds 2) Prove the following is true, or give a counterexample: If l is a nonzero scalar linear function on linear space X (which may be finite or infinite) and a is an arbitrary scalar, there exists a vector x in X st l(x

Economics : Equations, Quantity and Profit

A company manufacturers and sells a product. The estimated demand and cost functions are as below: Demand P = 16000 -2Q(squared) 0< Q < 85 Total cost 1000q = 100000 Where p is unit price (in £'s) q is quantity, tc is total cost (in £'s) A) Find the equation for total revenue hence an equation for profit. B) Find t
