The Right Triangle Review assigned yesterday is due tomorrow. You will have time in class to finish your poster tomorrow as well.

Start reading Chapter 19 from the text, specifically pages 493-500, up to the section titled “Alternative alternatives”

From pages 511-512, do exercises 1, 3, 5.

We have started the final phase of our miniature golf project: designing our own golf holes.

Your homework, due Friday, is this Right Triangle Side Ratio Practice sheet. You’re asked to find the missing angles and side lengths of various triangles, using the techniques we discussed in class. Use the Side Ratio Reference Sheet, as well as this video you watched as a part of Phase 3 as a guideline for your work here!

Watch the following eMathInstruction videos and take appropriate notes. Note sheets can be found on this page (and yes, some of these notes pages may look familiar).

- Video 1 – Reintroduction to Right Triangle Trigonometry (you can skip this if you remember sine/cosine/tangent from Geometry)
- Video 2 – Finding Missing Sides of a Right Triangle
- Video 3 – Trigonometric Applications

After watching these videos, you have a choice:

- Complete the corresponding homework assignment sheets that correspond to these lessons from Kirk Weiler’s eMathInstruction website (Lessons 4 and 5), or
- Complete the following IXL modules up to a score of at least 80

From chapter 18, do exercises 3, 4, 8, 24, and 27.

From pages 490-492, do exercises 18, 20, 29, 31, 35

Finish reading chapter 18, pages 480-488

From the exercises on pages 489-491, do 6, 17, 19, 21

We had our quiz on Unit 5 in class, and so your homework is the usual two-sided Math Riddle sheet, this one about the Pythagorean Theorem. Do one side (your choice!) for homework. Do both sides for extra credit on the quiz.

Read pages 473-479 in chapter 18. We will have a **reading quiz** in class tomorrow featuring the Just Checking questions from this reading. You will be allowed notes!

From chapter 17 (page 472), do exercises 55 and 57

From chapter 16 (pages 489-490), do exercises 5, 7, 9

Your quiz on Unit 5, the final assessment of the unit, will be **tomorrow**. Work on the Unit 5 review you got in class, work on some additional IXL review modules, and review the lesson videos posted below.

- HW 5.7 – Unit 5 Quiz Review
- Quiz Review Solutions
- Video Archive
- Review of existing exponent shortcuts (From Algebra 1)
- Negative exponents
- Evaluating rational exponents
- Solving radical equations (you can stop at the 5:00 mark, as the examples after that point are beyond what we will do in this class)
- Solving for variable in exponent using base equality
- Evaluating logarithms

- L.13 – Solve radical equations
- M.5 Simplify expressions involving rational exponents I
- M.6 Simplify expressions involving rational exponents II
- R.1 – Convert between exponential and logarithmic form: rational bases
- R.4 – Evaluate logarithms – assigned 2/5 to a score of at least 80
- S.4 – Solve exponential equations using equal bases – assigned 2/5 to a score of at least 80

From pages 470-471, do exercises 38, 43, 44, 45

Our quiz on Unit 5 will be on **Thursday, February 7**. Your last Powers Quiz opportunity will be tomorrow.

We spent today working on IXL review. Of the modules linked below, your assignment is to work on M.1, R.4, and S.4, all to a score of at least an 80. Remember that any score beyond 80 will count as extra credit in your homework grade!

Finish reading chapter 17, pages 453-464

From the exercises on pages 468-470, do 29, 35, 36, and 39.

The last topic from this unit is an introduction to the concept of logarithms, which is a pretty big part of the full Algebra 2 curriculum, but not one that has a lot of focus for us in Intermediate Algebra.

**Today’s Links:**

- HW 5.5 – Evaluating Logarithms
- Copy of notes
- Lesson video – Evaluating logarithms

**Cumulative IXL Review Modules **(newly added modules are in **bold**)

Read pages 445-453, up to the section on the Sampling Distribution of the Mean

From pages 465-467, do exercises 6, 11, 13, 15

Today’s lesson was about solving equations when the variable is in the exponent. The trick is to get both sides of the equation to be in terms of the same base, which is why having a good familiarity with various powers of bases 2-10 is so useful (and why I’ve been quizzing you on these daily).

Welcome to February!

By Monday, please work on the Unit 4 Practice Exam, pages 439-443. Complete the **odd numbered** multiple choice questions, as well as **free response question 2**. Do this on a separate piece of paper; you’ll be trading papers and grading each others’ responses!

We expanded on the use of rational exponents today, this time in the context of using them to solve equations.

A reminder: because I want you to be able to work through this chapter without relying on the calculator, we will have a daily Powers Quiz. I will choose 10 powers from the table you made on HW 5.1 and ask you to evaluate them **without using the calculator** in a brief, timed quiz. We will do this **every day** through the unit, and only your **highest grade** on any one quiz will be the one used in your Unit 5 grade.

We will have our group redo of the Unit 4 test in class tomorrow. The extra credit puzzles you got today should be turned in tomorrow as well.
