In the book “Not For Profit” Martha C. Nussbaum discusses how she believes the humanities is needed in modern day democracy and the important role it plays when producing informed citizens that are able to think critically. Her whole book points to the humanities as being the key to a successful democracy and should be taken into account when comparing different nation’s form of democracy. One would need to read the whole book in its entirety to fully understand her argument for the role of humanities

integer number of plants: 0‚ 1‚ 2‚.... Building Q plants costs each firm 3.5 × Q dollars. Each plant produces one unit of SOMA. If firm 1 builds Q1 plants and firm 2 builds Q2 plants‚ the market price p for one unit of SOMA will be 9 − (Q1 + Q2). For example‚ if firm 1 builds 2 plants and firm 2 builds 4 plants‚ the market price will be 9 − (2 + 4) = 3 per unit. At this price firm 1 will make a profit of 2 × 3 − 2 × 3.5 = −1 while firm 2 will make a profit of 4×3−4×3.5 = −2. Assume‚ no firm will

7 Ordinary Differential Equations Matlab has several different functions for the numerical solution of ordinary differential equations. This chapter describes the simplest of these functions and then compares all of the functions for efficiency‚ accuracy‚ and special features. Stiffness is a subtle concept that plays an important role in these comparisons. 7.1 Integrating Differential Equations The initial value problem for an ordinary differential equation involves finding a function

quadratic equation is an equation that has a second-degree term and no higher terms. A second-degree term is a variable raised to the second power‚ like x2. When you graph a quadratic equation‚ you get a parabola‚ and the solutions to the quadratic equation represent where the parabola crosses the x-axis. A quadratic equation can be written in the form: quadratic equation‚ where a‚ b‚ and c are numbers (a ≠0)‚ and x is the variable. x is a solution (or a root) if it satisfies the equation ax2 +

Abstract Have you ever wondered how not-for-profit organizations are not-for-profit? Or how not-for-profit organizations can operate at an accounting profit but still be considered a not-for-profit organization? Over the year’‚ not-for-profit organizations have had many changes in rules and regulations set forth for not-for-profit organizations to abide by. There are three major financial statements involved with not-for-profit organizations and one voluntary financial statement‚ plus four key governmental

ECON 600 Lecture 3: Profit Maximization I. The Concept of Profit Maximization Profit is defined as total revenue minus total cost. Π = TR – TC (We use Π to stand for profit because we use P for something else: price.) Total revenue simply means the total amount of money that the firm receives from sales of its product or other sources. Total cost means the cost of all factors of production. But – and this is crucial – we have to think in terms of opportunity cost‚ not just explicit

Heat Equation from Partial Differential Equations An Introduction (Strauss) These notes were written based on a number of courses I taught over the years in the U.S.‚ Greece and the U.K. They form the core material for an undergraduate course on Markov chains in discrete time. There are‚ of course‚ dozens of good books on the topic. The only new thing here is that I give emphasis to probabilistic methods as soon as possible. Also‚ I introduce stationarity before even talking about state classification

While the ultimate goal is the same‚ to determine the value(s) that hold true for the equation‚ solving quadratic equations requires much more than simply isolating the variable‚ as is required in solving linear equations. This piece will outline the different types of quadratic equations‚ strategies for solving each type‚ as well as other methods of solutions such as Completing the Square and using the Quadratic Formula. Knowledge of factoring perfect square trinomials and simplifying radical expression
