This can be handy when you need to solve a quadratic equation in real life, and I could use it at work to find out the lowest price that certain steaks or roast can be sold at while the company is still making a nice profit to insure a raise in my…
Week 1 DQ 4 Imagine your younger relative—of middle school age—was taking an algebra course and asked for your help. How would you teach the multiplication of polynomials to her?…
Real numbers, integers and rational/irrational numbers are used frequently in everyday life. Stock Market, buying gas, doing inventory, tipping your waiter at a restaurant, baking, school grades, tuning to a radio station and the list goes on and on.…
We can use this to do mathematical conversions to determine mass, volume, and number of atoms or molecules in a given substance. For example let’s check out this video to convert moles methane (CH4) to grams of methane. http://www.sciencegeek.net/Chemistry/Video/Unit4/GMV2.shtml…
Coefficients show the correct proportions of atoms and molecules in a chemical reaction. They are normal sized numbers placed at the beginning of the chemical formulas in a chemical reaction during the process of balancing. They tell how many of an entire chemical formula is in a reaction.…
Descartes rule is really helpful because it eliminates the long list of possible rational roots and you can tell how many positives or negatives roots you will have. Fundamental Theorem of Algebra finds the maximum number of zeros which includes real and complex numbers.…
Firefighters can use algebra to find out how fast a fire is spreading and to create a plan to stop it.…
Rational equations can be used to get a general idea about the rate at which a job can be completed. This can be really useful for business owners and other areas of daily life.…
University policies are subject to change. Be sure to read the policies at the beginning of each class. Policies may be slightly different depending on the modality in which you attend class. If you have recently changed modalities, read the policies governing your current class modality. Course Materials Lial, M., Hestwood, D., Hornsby, J., & McGinnis, T. (2010).

We use algebra in many different ways. People who understand algebra find it easy, believe it or not. The people who struggle and suffer with it and learn to hate it are the ones trying to skip understanding and just memorize procedures. I will then give the person an example of what algebra is all about. Like this one about quadratic equations A popular example of a parabola in the real world is the trajectory of a ball in free flight. As you throw a ball, it first goes up and forward, then falls down while continuing to travel forward, thus forming an inverted parabola path. A parabolic motion also occurs when a basketball bounces on a hard floor. Another example is a baseball hit by a…
“…The math we learn in the classroom has no relation to the quantitative reasoning we need on the job.” (Hacker, 2) When will the average person actually need to use the quadratic equation? I know that I will never use it in any job I have, so what is the point to learning it? Algebra isn’t critical for day to day decisions.…
Pi is used a lot in planetology. It is used to search for planets outside our solar systems. It is also used for characterizing them. These planets are called exoplanets. The volume of a planet is approximately 4/3 pi times the radius^3. This formula is necessary to finding the density of a planet. The density of something is equivalent to mass/volume. The density of a planet can tell if a plant is rocky, gaseous, or in between. You can also use pi in the calculations surrounding the atmosphere of an exoplanet. This is because the atmosphere can be represented spherically and spheres always involve pi. You can also use pi to estimate the number of seconds per year-10 million seconds pi. Lastly, pi is also used in the optics equations related…
Algebra, some of us fear it while some of us embrace it, algebra is not “arithmetic with letters” it is better described as a way of thinking. At its most fundamental level, arithmetic and algebra are two different forms of thinking about numerical issues. Many of these examples have been taken from our classroom discussions while others are examples I have discovered in my own research for this paper, several examples of each will be cited.…
One very common use of algebra is when you go shopping. An example of this is when you have a certain number of objects that need to fit into a certain number of bags. Another use of algebra is filling up a gas tank. When doing this you have to calculate the cost of the amount going into your tank. An example of a use of algebra that it not very common is determining things like interest for loans. This is an important part of life and it is critical that one knows how to figure this type of math out correctly. An additional use of algebra in day to day life is budgeting. It is imperative to know how to do this so that you can correctly plan what to do with your money and how much you will have left after paying for necessary things. An added usage of algebra is when one is paying bills. By the means of algebra one will be able to figure out how much to pay and the amount of money they have…
You can use the scientific method in making a recipe or a news story. You can use all different kinds of real life examples as long as you have a goal, data, check over of the data, and your evaluation.(4)Why it is so important is you can use these steps to do anything you want to do because it makes you focus on your theory and keeps you organized. How all these real life examples can be used for scientific method is for it to be trial and error and it will work for anything.…
