University of Phoenix math 140 discussions week 6 – Description
discussion #1
Create an ordered pair of points in the following way (birth month as a number, order of birth) and (number of letters in your last name, your shoe size rounded up to a whole number). For example, someone who was born in July (which is the 7th month) and is the oldest child (or first child) in the family would have a point (7, 1). In addition, if there are 6 letters in the last name and the shoe size is 8. The second point would be (6, 8). use your two points and do the following, showing the formulas, work, and explanations as you go.
State the points before you start working. For example: “My points are (7, 1) and (6, 8).”
Compute the slope, , using the slope formula. If you compute a decimal, make sure to convert it to a fraction, so it is an exact answer.
Use the point-slope form of a line to create the equation of the line going through the two points. If you have a special case of a line that is not a function, then just write the equation of the line and explain why you can’t use the point-slope formula.
If possible, put the line in slope-intercept form and identify the y-intercept value as an ordered pair. Again, for those with special cases, give the equation of the line and the x-intercept.
Use Desmos or Graphmatica to graph your line. Adjust the axes so the y-intercept is shown and labeled. If your line does not have a y-intercept, still graph it, show and label the x-intercept, and explain why, in terms of graphing, it is not a function.
Birth month is 11 and 1st born. (#of letters in last name 7, shoe size 8).
Discussion # 2
You should be able to use this how-to guide to solve a problem like this, no matter what the numerical values are in the problem.For this discussion, you will be able to pick one of the learning objectives we have covered in Module 6 or Module 7 and develop a step-by-step list on how to solve the problem generically. Your post will contain all of the following:
State the learning objective that you are covering.
The How-to Guide you created for solving a generic form of the objective in your own words.
Give an example to illustrate the learning objective.
discussion #3
In this short response and discussion, you will dive deeper into the applications of logarithmic functions to uncover your curiosity. Complete the following:
Research applications of logarithmic functions as mathematical models. Some ideas include but are not limited to: pH (acidity of solutions), intensity of sound (decibels), brightness of stars, human memory, progress over time in a sport, and profit over time.
Choose an area of interest from above or provide one of your own, and explain how logarithmic functions are used.
Provide at least one example.
The initial post of your discovery should be at least 250–500 words in length. Use current APA format to cite your sources (e.g., from library books, textbooks, and the Web). Your post must contain some of your own thoughts and reactions, in addition to any citations you make.Remember that Wikipedia is not an academically reliable source and should not be used or referenced in the post. However, it is a good place to get some potential key terms, names of people associated with logarithms, etc.
