Intermediate Algebra Assignment for 5/20 (Test Warning!)

We did some more work with Linear vs Exponential models today, and the homework is more of the same. We’ll start reviewing the unit as a whole tomorrow, with our planned Unit 9 test on Friday, May 24th

Today’s assignment is about deciding whether a linear or exponential model is most appropriate for a set of data. The short version is make a scatterplot and examine the picture. If it looks straight, use a linear model. If it looks curved, use an exponential one.

More of the same today as yesterday, only this time working with exponential regression instead of linear.

Not all linear or exponential relationships are as perfectly defined as we’ve seen. Sometimes the fit of a line or a curve is a bit more approximate, and finding the equation for these functions is a bit more tricky. Fortunately, your calculator provides you with a helpful tool in doing just this: Regression. The instructions for getting your calculator to do this are in today’s notes. They’re a little tricky (lots of button pushes), but pretty straightforward.

We’re in the last phase of Unit 9, which starts off by reviewing the difference between linear and exponential equations and deriving the formulas for these equations from a table of values.

8th period: Please watch this video to introduce the big idea behind today’s lesson (late in the video, the term “gradient” refers to the slope of the line tangent to the curve at a point), then watch this video from 14:30 to 18:15 for some examples of how to use this formula. Your homework will be the same as below.


We expanded on compound interest today, extending the concept to the idea of “compounding continuously,” which in turn led us to the fascinating mathematical constant of e. If you’re interested in learning more about e, click the link!

Today, we reaffirmed that the Expected Value is a long-term average. Meaning the results of a small handful of trials are unlikely to produce the same average as the expected value, however increasing the number of trials will produce averages more in line with what you expect.

Don’t forget that our test on this unit will be on Thursday, April 11th!

We did some more practice with calculating Expected Value today, and the homework is to continue that work.

Our test on this unit will be on Thursday, April 11th. If you will not be in school that day, you must make up the test before you leave. NO EXCEPTIONS

Permutations and combinations tend to be tricky to figure out when you first encounter them, so we spent some more time looking at examples, including a modification to the concept to find arrangements of letters in a word.

The next part of the “counting” part of this unit is understanding the difference between two common patterns of counting: permutations and combinations. In brief, permutations are used to count the number of arrangements of objects, specifically when order matters like with ranked lists, unique assignments, or sequences. Combinations are used to count the number of groups of objects, specifically when order doesn’t matter like with committees or batches.

We did some more work with the counting principle today, using it in a variety of applications. The trick is to carefully sort out the number of choices you have to make and the number of options you have for each choice.

We started our second-to-last unit today, about tools of probability. Probability is all about chances and odds, determining how likely various events are to occur. We’ve started with some very basic ideas of probability, but we will quickly move to some more complicated and nuanced applications.

We did some more work with the Law of Cosines today, specifically looking at two cases where it is useful: when given two sides and a single angle between them (SAS) and when given three sides but no angles at all (SSS). Note that this second case is exactly what your poster will feature!
