# AP Statistics Assignment for 1/11, plus Quiz Warning

From the exercises on page 409-411, do exercises 32, 43, 49, and 53. There will be a quiz on Chapter 15 in class on Tuesday, January 16.

# Intermediate Algebra 2 Assignment for 1/10

Today’s homework is HW 4.10 – Simplifying Square Roots of Negatives, and in particular how imaginary numbers are used to accomplish this goal. You can find the notes here and see some more examples in this videoPLEASE REMEMBER: negative radicands do not multiply. Pull out the i first, before you multiply.

# Fractals & Chaos Assignment for 1/10

There is one final article that I want you to read: Ivars Peterson’s Bordering on Infinity. While this article was published in Science News back in 1991, the questions that it poses about the connectedness of the Mandelbrot Set still plague mathematicians today. We’ll chat briefly about this article in class tomorrow.

# Intermediate Algebra 2 Assignment for 1/9

We’ve started the second section of Unit 4, learning about complex and imaginary numbers. This is a new category of number, much like irrational or negative numbers, that mathematicians developed to handle equations that they previously had no ability to solve. We watched two videos to introduce this topic, but I recommend you watch the full story found here.

Your homework tonight is HW 4.9 – Introduction to Complex Numbers. You can find the notes for this assignment here.

# Intermediate Algebra 2 Assignment for 1/8

We had our Simplest Radical Form quiz in class today, so the homework is the usual post-quiz assignment: complete one side of HW 4.8 (your choice) for a homework credit, and complete both sides for extra credit on your quiz. You must show all work for extra credit!

# AP Statistics Assignment for 1/8

Read pages 389-395 from chapter 15, up to “More about means/variations” then do exercise 52 from page 388 and exercises 3 5, 10, 17, 22 from pages 407-408

# Intermediate Algebra 2 Assignment for 1/4

Your first quiz of Unit 4 will be tomorrow (or, if school is canceled, on Monday). You should review the study notes we did in class and complete HW 4.7 – Quiz Review 2 (you can find my solutions here).

And don’t forget to work on some IXL practice!

Finish reading chapter 14 (pages 371-383) and from the exercises on pages 384-388, do 16, 22, 36, and 51.

# Intermediate Algebra 2 Assignment for 1/3

We have commenced review for our quiz on Friday, and your homework tonight is HW 4.6 – Quiz Review 1. You’ll have plenty of time tomorrow to ask questions and get some extra practice in. But don’t forget that the IXL modules below would be a great place to start!

Start reading chapter 14, pages 363-371 (up to “Tables vs Venn Diagrams”)

From the exercises on pages 383-384, do 3, 4, 9, 11

# Intermediate Algebra 2 Assignment for 1/2, plus a reminder

First, a reminder of the homework protocol.

• Homework is assigned every day and due the following day. Homework is assigned every day and due the following day.
• Late assignments will be accepted ONE day late for half-credit.
• If you are ABSENT FROM CLASS, you are expected to turn in the assignment you would have submitted on that day on the day that you return. You will be given one additional day per day of absence to turn in the assignments you missed.
• For example: Goofus is present on Monday and absent on Tuesday. On Wednesday, he must turn in Monday’s homework, and he has until Thursday to turn in Tuesday’s assignment. He gets no extra time on Wednesday’s assignment; that is due Thursday also.
• If you are having difficulty with an assignment, it is your responsibility to arrange extra help. We usually have time to discuss one or two topics in class, but if that’s not enough please come and see me!
• New for 2018: Any student who has 3 or more unexcused missing assignments will be assigned a lunch or after school detention to make up the missing work. This work will or will not be accepted for credit based on my discretion!

We have a quiz on Friday, January 5 about the first half of the unit, all about working with radical expressions. This will include content from today’s homework: HW 4.5 – Simplifying Radicals with Variables. You can find the notes here and some addition examples in the video here.

# AP Statistics Assignment for 1/2

Read chapter 13 (pages 343-357). Read over the first few pages carefully, but it’s okay to start skimming once you hit page 348 (“Formal Probability”), since those sections are a review of some elementary ideas of probability.

From the exercises at the end (pages 358-359), do 8, 10, 13, 23, 25, 27.

# AP Statistics Assignment for Winter Break

Submit your written report electronically by sharing with me. Use the standard filename format: “LastName.LastName.LastName.MidYear Project”. Share only your written report document, but please include links to any other materials and/or your presentation in the appendix.

Submit peer evaluations for every member of your group, including yourself, by using this form. Please submit multiple copies of the form, one for each member.

Finally, take some time to relax over this break, but please also take some time to review the course so far by working on the Unit 3 Practice Exam multiple choice questions (pages 336-341, questions 1-19, odd-numbers only!) as well as Free Response question 1. We’ll start things off when we get back with a review of the answers to these questions.

# Intermediate Algebra 2 Assignment for 12/21

The use of radical expressions as the inverse of exponents extends beyond the power of two. While the square root is the inverse operation for a power of 2, there are cube roots, fourth roots, fifth roots, and so on for other powers. Generally, we call these “Nth roots.” Your homework tonight is HW 4.4 – Evaluating Nth Roots. I’ve uploaded the notes here, and you can check out this video for some more examples (and instructions for evaluating nth roots on the calculator).

# Intermediate Algebra 2 Assignment for 12/20

While we did some work with dividing radical expressions on Monday, we expanded on it today to make the observation that, in general, we try not to leave any radicals in the denominator of an expression. The process of fixing this is called rationalizing, and so your homework for tonight is HW 4.3 – Rationalizing Denominators. As usual, you can find the notes here and a video with some extra examples here.

# Intermediate Algebra 2 Assignment for 12/19

We continued to work with radical expressions today, this time multiplying (and distributing) them. The homework is HW 4.2 – Multiplying Radicals. As usual, find the notes here and check out some videos of more examples here. You’ll note that this video uses a different method to simplify radicals than what we typically use.
