Introduction:

A linear equation is an algebraic equation in which the highest power of the unknown variable is a unit. Linear equation is in the form of where a, b and c are constants and x and y are the variables of the equation (PBS. Mathline). A linear equation produces a straight line graph when plotted to scale on a graph paper.

Solving a System of Linear Equations

A system of equations is the case when we have more than one linear equation. (When there are two or more equations). For elementary studies, the number of unknowns in the system is equal to the number of equations in the system. We ...

Introduction

Knowing the market is very important for a firm as it has to base its policies and profit maximizing decisions based on the market characteristics. In a perfectly competitive market the firms follow the price determines by the industry. On the other hand a monopolist sets the price and quantity based on the profit maximizing conditions. The monopolist earns higher profit than the firm under a competitive sitation. In a monopolistic competition the firms have to innovate so that the products can be differentiated from the products of the consumer. The oligopoly form of market is characterized by the ...

Introduction

The purpose of this experiment was to verify Newton’s second law of motion. The force and acceleration data was collected by Logger Pro for a cart moved back and forth. This data was used to analyse the relationship between force, acceleration and mass. It was hypothesised that the acceleration would directly be proportional to applied force but inversely proportional to the mass of the cart.

- When you push on an object, how does the magnitude of the forces affect its motion? If you push harder, is the change in motion smaller or larger? Do you think is a direct ...

Lipids are a group of structurally diverse hydrophobic compounds that are not very soluble in water. Cholesterol is a common lipid that can be obtained from the diet and is synthesized in most cells of the human body. It is a component of cell membranes, maintains membrane fluidity, and acts as the precursor of other important biological compounds such as steroid hormones and bile salts (Smith, Marks, and Lieberman 54, 163).
High concentrations of cholesterol in the blood can cause accumulation of fatty deposits on arterial walls that can lead to the formation of atherosclerotic plaques, which are associated with heart ...

In order to define and understand a vector space, it is important to first define and understand a few other related terms. To begin with, a vector is a directed line segment, and its extension to n-dimensions leads to a vector space. The addition operation on two ordered pairs of a set is the ordered pair containing the sum of the respective elements. This is true for ‘n’ number of ordered pairs as well (n-dimensional vector space). Similarly, the scalar product operation on an ordered pair of a set is the ordered pair containing the product of the scalar with the respective elements (“Vector ...

Introduction

Fourier analysis is a field of mathematics that studies how general functions can be approximated or represented by the addition of simple trigonometric functions. Fourier analysis is named after a man who proved that representing a mathematical function in the form of a sum of a trigonometric function simplifies the inquiry into heat propagation. Joseph Fourier envisioned the Fourier series, a concept from which Fourier analysis grew. Presently, vast spectrums of mathematics involve Fourier analysis as a subject. The subject spans through the field of engineering and sciences. In these two fields, Fourier analysis involves the process through which a function is decomposed into simpler functions. The ...

“If it has ‘science’ in its name, it ain’t (Minnick).” Those words were said to this writer by the smartest person he ever knew personally, a man with PhDs in Mathematics and Physics, a true scientist. He went on to explain that science, if it is science, can be reduced to mathematics and then can predict. “Science can generate electricity or flatten cities,” he said. The problem, of course, is that whenever one deals with the “soft sciences,” political science or economics (the dismal science) or sociology or history or any of the disciplines that are housed in ...

Abstract

Individuals and business organizations with investment potential or the desire to become investors often find themselves having limited capital to undertake the desired projects. Additionally, most investors are often confused when carrying out analysis to assess the risk of the various portfolio in which they intend to invest their resources. The governments have developmental projects that require more financial resources than their revenue due to budget deficits. Having excess money in the circulation is dangerous to an economy because it results in excess aggregate demand that produces inflationary gaps. As such, the government must regulate money supply to ensure ...

The Federal Reserve has one of the most unique duties in the world. Tasked with keeping both employment high and inflation low, it is the only central banking authority in the world that performs both functions as its mission. Studies performed by A. Phillips describe the inverse relationship between unemployment and the inflation of real wages. The Federal Reserve and Congress enact policies to counteract the inverse nature of unemployment and inflation. The Fed achieves its goals with manipulation of monetary policy, which is the control of the monetary supply, while Congress controls fiscal policy to help achieve similar ...

It is safe to say that in the recent decades, the topic of health has become a subject for heated discussions around the world. As the ecological situation on our planet gets worse, people start looking for different sources of health. One of such sources is proper nutrition also known as a healthy diet. There are different approaches to defining what kind of diet is actually healthy, and different experts provide their own ideas on ideal food pyramids. As a result, people get confused about what types of food are safe to it and what types of products should ...

Human development is a process of providing mechanisms through which people can flourish and attain self-actualization in their lives. The rationale of human development as a process goes beyond focusing on economic development as an indicator of people’s wellbeing. It therefore incorporates other dimensions which are crucial in establishing the extent to which people would describe quality life. Traditionally, most economists have used quantitative indicators such as GDP Per capita as a measure of people’s wellbeing in a particular economy.
The reality is however, different because quantitative indicators such as these are limited to assessing economic success ...

Introduction

The depiction of female characters in television has long been one of Feminism’s great worries and battles. Throughout the decades, females have been shown as one dimensional and weak, often reduced to mere companions or prizes for the lead, male characters. The popular television saga Game of Thrones has long come under the view of these critics, yet many have reached opposite conclusions. Even though some contend that it is deeply Feminist, other critics believe that it is extremely misogynist, painting women in a negative light. The present text will argue that historical considerations and character development show ...

The ALARA principle is used in industrial radiography to protect workers during the testing of weld seams in a tank or pipeline.
(ALARA) or “as low as reasonably achievable” is a phrase used in the United States to denote minimization of exposure to radiation. Workers exposed to radiation can maintain their radiation doses ALARA by reducing the time spent near sources of radiation, increasing their distance from radiation sources and establishing a shielding mechanism between them and radiation sources.
A great way of achieving ALARA is to half the exposure time to radiation as this would reduce the radiation ...

Article Summary
Existing literature suggests that nurse staffing influences patient safety. Improved nurse staffing has been shown to promote optimal patient outcomes such as reduced medical errors, healthcare associated infections, and inpatient stays. A nurse-patient ratio of 4:1 or less has been shown to promote the most optimal patient outcomes. In addition to the impact on patient outcomes, nurse staffing levels also have potential impact on job satisfaction and retention of nurses (Hairr, Salisbury, Johannsson, & Redfern-Vance, 2014). This paper will summarize a study by Hairr, Salisbury, Johannsson, & Redfern-Vance (2014) that examined the link between nurse staffing, job satisfaction, and ...

Introduction

The law of demand tells us that there is an inverse relationship between price and quantity demanded. That means if a producer reduces the price the demand for the product will increase and vice versa. But just knowing the inverse relationship is not enough for a business firm. It is more important to know the extent to which the demand changes with the change in price. Thus price elasticity of demand is an important tool to decide upon the appropriate pricing strategy. In this paper we are going to present the concept of price elasticity of demand, how it ...

The predictability of radish (Raphanussativus) seed germination was investigated using student T number-1 and tuckey test with the data collected from the measuring root length after being treated with different factors. Radish seeds are an edible root vegetable that was domesticated in Europe and pre-Roman times. Its significance as a vegetable is considered to be due to its short period of emergence. In order to manage radishes, we gathered more detailed information required on its seed bank dynamics. Conducting this experiment helped us gather more knowledge of the factors regulating germination radish seeds. These information helped ...

Work Load in Campus Students

Work Load in Campus Students
For this project, a total of 20 students from Campus where interviewed regarding the amount of credits they are taking, as well as how many hours per week they work in paid employment. The amount of credits taken constitute the variable ‘Class Load’, while the amount of hours per week at a paid job constitute the variable ‘Work Load’. It could be argued that students who take more credits have less time to work, or vice versa, so an inverse correlation is expected. Descriptive statistics were calculated and presented as mean ± standard deviation for each ...

Question 1
If the price elasticity of demand for firm X’s product is -1.75, lowering its price will result in an increase in total revenue. This is because a negative price elasticity of demand implies an inverse relationship between price and quantity demanded. It indicates that an increase in price leads to a decline in quantity demanded and a decline in price leads to an increase in quantity demanded. In addition, the price elasticity of demand is more than 1 in absolute terms hence a change in price leads to a more than proportionate change in quantity demanded. A 1% decrease in ...

Introduction

Investors prefer safer to riskier stocks since it provides a perceived security and there alternative to a risky investment or stock is the incentive in form of higher returns. In depth, the market prices are to be set such that investors expect riskier stocks to deliver higher returns although the higher returns are not to be viewed as dependable since if the risky stocks are to be counted on to deliver higher returns than the safer investments or stocks then they are to be considered not risky like demonstrated (LAOPODIS 2012). This expected high returns are valuated so as to attract ...

Question 1

Beta is a measure of a project’s risk relative to the entire market .

Abstract
The trade off theory advocates that the management consider the trade off between the benefits resulting from tax shields verses costs, such as bankruptcy costs, interest costs and agency costs among others. The ability of management to obtain external financing is determined by size of company, profitability, opportunities for growth among other factors. The trade off theory indicates that the management gears at obtaining all the benefits associated with external financing. The M and M theory (1963) has the argument that changing the capital structure may not make the share holder any better off. The contradiction of ...
