Many people are intimidated and afraid of mathematics and algebra largely due to the fact that upon first glance, certain problems or expressions may seem overwhelmingly large, difficult, or complicated. Along with remembering formulas, this can often times lead to anger, confusion, and frustration. There are several very important key elements and aspects involved within mathematics that helps combat this confusion and frustration and can even help the most intimidated person feel at ease and comfortable with solving these problems. This particular report will demonstrate the importance of understanding certain key mathematical principles and components and show how understanding and utilizing certain mathematical definitions can help limit the amount of confusion and intimidation one may have. These definitions include but are not limited to simplifying, adding like terms, coefficient, distributive property, and removing parenthesis. This report will also demonstrate how much easier and more simplistic mathematics and algebra can be by remembering and utilizing just a few important concepts. Example 1:
2^a(a-5) +4(a-5) This is the first example that will be used. The variable a is used. This particular example has a coefficient of two.
Step 1:
The distributive property can be utilized to multiply 2a by everything inside of the parenthesis (a-5 in this case) resulting in:
2a^2-10a
Step 2:
The distributive property is used once again to multiply 4 by everything in the parenthesis (a-5 again) resulting in:
4a-20
These two steps demonstrate how the distributive property is used in an effort to remove parenthesis along with making the problem much smaller, less confusing, and easier to work with.
Step 3:
The next step involved should be to put the results from the following two steps together to form one expression:
2a^2-10a+4a-20
Step 4:
The final step involved in this particular example is to simplify the expression even further using a concept known as adding like terms. What this means is that variables are matched and sometimes added or subtracted along with whole numbers to get an expression that can no longer be simplified or broken down. For this example we receive a final expression of:
2a^2-6a-20 this particular expression is simplified and can no longer be broken down any further.

Example 2:
2w-3 +3(w-4) -5(w-6) This is our next example and shows that mathematics and algebra can look even more confusing when compared to the previous example. Distributive property is used to remove parenthesis resulting in:
2w -3 +3w -12 -5w +30 Terms are matched and added together (adding like terms and coefficients) resulting in:
5w -3 -12 -5w +30 which can be simplified even further one last time resulting in:
-15 +30 or 15
Example 3: 0.05(0.3m +35n) -0.8 (-0.09n -22m) This particular example may look like the most complicated out of the previous examples but in fact becomes one of the easiest to solve by remembering the definitions and components utilized in the previous examples. Many people may be inclined to believe that extra steps may be involved when dealing with decimal numbers when in fact; the same exact steps are used.
Distributive property removing parenthesis:
0.015m+1.75n+0.072n+17.6m
Adding Like terms and simplification:
17.615m + 1.822n<<simplest form cannot be broken down any further. In conclusion, mathematics and algebra can at times look very overwhelming and confusing causing many people to become frustrated or to give up. With the basic understanding of key mathematical components and definitions these rather lengthy and seemingly large equations become much smaller and easier to work with. By using distributive properties, one can remove confusing parenthesis. One can then add like terms to shorten the problem and then finally simplify the expression into its smallest and simplest form.

Traffic Modeling

...Traffic Modeling Paper Concepts of math can be displayed and solved in many different ways. There are equations, graphs, and word problems and several concepts that can be used as examples to help solve mathematical issues. In week four of this College Algebra class Learning Team B was present with an assignment involving a traffic model. The traffic model is the key to helping Learning Team B solve the problems the assignment presents. The traffic model represents a number of cars within the area at any given time represented by letters. Learning team B must solve questions based on this model. There are several equations that were made in order to prove that the numbers of cars entering and leaving each intersection must be equal to keep traffic moving smoothly. Variables f and g are independent variables. This means that variables a through e are dependent on variables f and g. The number of cars at intersection a depends on how many cars turn from intersection f. The number of cars at intersection b depends on how many cars turn right from intersections f and g. This tells you that there are infinitely many solutions since the number of cars that turn onto Elm from Oak, Pine, and Aspen vary. Similarly the number of cars that turn onto Maple from Oak, Pine, and Aspen also vary. To list two acceptable traffic flows first let variable f be equal to 365 cars/hr and let variable g be equal to 400 cars/hr. Variable a would be equal to 850-365, which equals 485 cars/hr.......

Misconceptions of Algebra

...Diagnostic Algebra Assessment Definitions Categories Equality Symbol Misconception Graphing Misconception Definition Concept of a Variable Misconception Equality Symbol Misconception As algebra teachers, we all know how frustrating it can be to teach a particular concept and to have a percentage of our students not get it. We try different approaches and activities but to no avail. These students just do not seem to grasp the concept. Often, we blame the students for not trying hard enough. Worse yet, others blame us for not teaching students well enough. Students often learn the equality symbol misconception when they begin learning mathematics. Rather than understanding that the equal sign indicates equivalence between the expressions on the left side and the right side of an equation, students interpret the equal sign as meaning “do something” or the sign before the answer. This problem is exacerbated by many adults solving problems in the following way: 5 × 4 + 3 = ? 5 × 4 = 20 + 3 = 23 Students may also have difficulty understanding statements like 7 = 3 + 4 or 5 = 5, since these do not involve a problem on the left and an answer on the right. Falkner presented the following problem to 6th grade classes: 8 + 4 = [] + 5 All 145 students gave the answer of 12 or 17. It can be assumed that students got 12 since 8 + 4 = 12. The 17 may be from those who continued the problem: 12 + 5 = 17. Students with this misconception may also have difficulty with the idea that......

Prg/211 Calorie Count Tool

...Team B Calorie Count Tool PRG/211 May 5, 2014 Team B Calorie Count Tool PROBLEM STATEMENT Team B was asked to develop a program which would calculate the user’s daily intake of calories and measure those calories against the overall calories expended. The core purpose of this program will do two primary functions. First, it will record the user intake of calories as acquired through meals throughout the day. Second, the user will record caloric output associated with physical activity. This information will be calculated together to determine the caloric surplus or deficit for the user. In order for the program to execute accurately, and provide customized results, the user will be required to input personal data to include gender, age, weight, and height. This additional information is essential to determine the user’s default caloric burn rate, otherwise known as the basal metabolic rate (BMR). The BMR and the calories burned as a result of physical activity will be calculated against the intake of calories to determine the overall success for the user. As the program is executed it must: * Record user name, age, height, weight to enable more accurate calculations * Record the users specific caloric values entered for each meal * Record the user activity and caloric burn values for that activity * Calculate the basal metabolic rate (BMR) for the individual * Subtotal the total caloric values for the day * Combine the physical activity......

...Selection statements Selection is used to select which statements are to be performed next based on a condition being true or false. Relational expressions In the solution of many problems, different actions must be taken depending on the value of the data. The if statement in C I used to implement such s decision structure in its simplest form – that of selecting a statement to be executed only if a condition is satisfied. Syntax: if(condtion) statement executed if condition is true When an executing program encounters the if statement, the condition is evaluated to determine its numerical value, which is then interpreted as either true or false. If the condition evaluates to any non-0 value (positive or negative), the condition is considered as a “true” condition and the statement following the if is executed; otherwise this statement is not executed. Relational Operators In C Relational operator | Meaning | Example | < | Less than | age < 30 | > | Greater than | height > 6.2 | <= | Less than or equal to | taxable <= 200000 | >= | Greater than or equal to | temp >= 98.6 | == | Equal to | grade == 100 | != | Not equal to | number !=250 | In creating relational expressions, the relational operators must be typed exactly as given in the above table.

The change of owners did not cause a change in the composition of the team although a new coach was hired. Parks’s compensation and his responsibilities remained the same. Was this contract assignable? Facts of the Case: 1) Parks contract was assigned from the ABC Corporation to XYZ Corporation. 2) Parks compensation and his responsibilities remained the same. Issues: 1) The reason why we are in court today is to identify if Park’s contract was assignable. Rules of the Law: 1) Personal Service Contract – The parties agree that a personal service contract may be assigned. This allows the trade of an athlete from one team to another team. 2) Notice of Assignment – Assignee is under a duty to notify the obligor that the assignment has been made and performance must be rendered to the assignee. 3) Anti-Assignment Clause – Prohibits the assignment of rights under the contract. 4) Approval Clause – requires that the obligor approves any assignment of contract. Analysis & Conclusion: Since we do not have all the facts we can assume the following: 1) Parks contract did include the Personal service contract. 2) Notice of assignment was made by XYZ Corporation. 3) Parks contract did NOT include Anti-Assignment......

To do this I will first, briefly describe the event, supporting my outline with relevant information. I will then explore the event, and discuss why it is important and how it relates to the learning outcome. I will also be discussing why materials such as law and guidelines say this is important. I will then proceed to analyse the incident by breaking it down and picking out the main features of the experience, discussing why they are important, whilst linking the main points together. I will attempt to think about opposing arguments to what I have explored, and discuss the advantages and disadvantages of the arguments. Finally I will be using SMART goals, to create an action plan for future development. Explain incident with evidence Whilst on a shift, we had an elderly patient arrive on the ward.

...ASSIGNMENT - 3 Answers 1 Answer 2 Answer 3 4. For what types of workloads does SJF deliver the same turnaround times as FIFO? ANSWER: - In the above case if the jobs are same in size or the jobs periodically applied (i.e. first shortest job then later second shortest job and continues) then the turnaround time of SJF is same as FIFO. 5. For what types of workloads and quantum lengths does SJF deliver the same response times as RR? ANSWER: - The response time delivered by SJF is equal to the response time of RR but this happens only when all the jobs arrived are at the point when the planning quantum of RR is bigger than the bigger occupation to be administrations in order of increasing size. 6. What happens to response time with SJF as job lengths increase? Can you use the simulator to demonstrate the trend? ANSWER: - If you suppose the length of the job increases then average response time varies (increases).If every job is sorted in increasing job order than the last job response time will be equal to the sum of current job and previous (n-1) jobs. In this way if the size of the job increases the response time will also increases for all larger jobs. 7. What happens to response time with RR as quantum lengths increase? Can you write an equation that gives the worst-case response time, given N jobs? ANSWER: - In the case of RR, the response time increases as the quantum lengths increases. This happens because the waiting time of a process for its turn......

It has helped me out in those areas of different topics, but I just wish I had more time.

Pay for Eprformance

...Pre course assignment 2: Performance Related Pay The assignment is to write a paper about Performance Related Pay (2000 words) Performance Related Pay is receiving a great deal of attention. On the one hand (collective) labour agreements are increasingly including arrangements that relate to pay-forperformance, at the same time there is also strong resistance. Trade unions have never been enthusiastic proponents subject to certain conditions, but opinions are also divided in employers' circles. Pay-for-performance is even named as a root cause for the crisis of the financial sector and for the collapse of some companies. A number of companies have recently announced that they will abolish or change their pay- for-performance systems. When organizations have performance related pay systems in place, (front line) managers usually play an important role. They make pay decisions, or provide information for these decisions. The paper is also a preparation for a class debate about pay for performance in the fourth lecture. The debate will be about the statement: “The introduction of individual pay for performance contributes to an improvement in a company's (financial) performance” The paper will be written from one of three starting points: 1. You are against the statement: all arguments you discuss should underpin that the statement is false 2. You are in favour of the statement: all arguments you bring forward should underpin that the statements is true 3. You are undecided:......
