Real World Quadratic Functions Maximum profit. A chain store manager has been told by the main office that daily profit‚ P‚ is related to the number of clerks working that day‚ x‚ according to the function P = −25x2 + 300x. What number of clerks will maximize the profit‚ and what is the maximum possible profit? In order to find the point at which profit is maximized‚ I must find the critical points of the first derivative of the equation. Coefficient of x^2 is negative‚ so

A Study on Improving the Writing Ability of Middle School Students Based on Error Analysis Abstract: English writing plays a significant role in learning. However‚ for most middle school students‚ English writing‚ among the four basic skills‚ is the most difficult skill for them to master. One of the reasons may be that writing places high demands on accuracy‚ fluency‚ coherence and organization compared with other language skills; another reason may be that the English teachers

Using Polynomials in the “Real World” Polynomial functions are used in our everyday lives in a few different ways‚ this includes art‚ architecture‚ construction‚ financial planning‚ and manufacturing. We can also calculate how long it will take one person to do a job alone when we know how long it takes a group to get it done as well. Farmers on crop farms work dawn to dusk through the growing season to produce the grains‚ fruits‚ and vegetables that feed the country. These equations help them

The keywords in this article are Objective Function and Constraints‚ according to Heizer & Render (2008) Objective Function are mathematical expression expressed in linear programming designed to maximizes or minimizes some quantity‚ for example profit can maximized while the cost might be reduced. The objective function is also called effectiveness function‚ it is the mathematical expression of the objectives which

Boolean Functions - Computer Organization (IT 25) BOOLEAN FUNCTIONS A Boolean function consists of a binary variable denoting the function‚ an equals sign and an algebraic expressions formed by using binary variables the constants 0 and 1‚ the logic operation symbols‚ and parentheses. For a given value of the binary variables‚ Boolean function can be equal to either 1 or 0. Example: F = X + Y’Z The two parts of the expression X and Y’Z‚ are called terms of the function F. The function F is
