Why is it important to understand linear equations in business? What are some examples of how the concept of linear equations are used in your organization?

Decide whether the following sets are open, closes or neither. If a set is not open, find a point in the set for which there is no E-neighborhood contained in the set. If a set is not closed, find a limit point that is not contained in the set. (a) Q (b) N (c) {x E R : x > 0} (d) {0,1) = {x E R : 0 < x less the or equal to

Discuss whether the statement, (x + y)3 is equivalent to x3 + y3, is true or not. Identify a pair of values of x and y for which this statement is true and another pair of values for which it is not true.

17) The demand equation for a certain product is modeled by y = 50-√(0.01x+1) where x is the number of units demanded per day and y is the price per unit. a) Present a graph of the function. b) Approximate the demand if the price is $37.55. 18) Consider the function a) Present a graph of f(x) b) Solve f(x) = 0 c)

As a business owner there are many decisions that you need to make on a daily basis, such as ensuring you reach the highest production levels possible with your company's products. Your company produces two models of bicycles: Part I: using this scenario, solving by using each technique,of Graphing, Substitution, Elimination

For any two real numbers a and b, a < b if and only there exist a positive real number s such that a + s = b. Use this definition to prove that for any negative real number r, if a < b then a + r < b + r.

There are many applications used in the area of solving systems of equations. For example, systems of equations can be used to find the optimal number of items to produce to ensure the highest profit of those particular items. Systems of equations can be solved by four methods: graphing, substitution, elimination or with matrice

Write a linear equation describing the number of exports each year with x=91 representing 1991 and x=101 representing 2001. In 1991, about 10 billion dollars of goods were exported to China. By 2001 this amount had grown to 19 billion dollars.

I have included a Wave Equation problem with parts a-c, that has variable tension. It involves separation of variables, the Sturm-Liouville system, and an application to the "Rayleigh Quotient" involving the Eigenvalues. I have included notes on the Sturm-Liouville system with examples and properties. Please refer to these notes
