Sorry I missed the last couple of days. I’m really feeling the end of semester crunch. So tired…
Algebra 2 – Review night tonight 6:30-7:30 (later if absolutely needed) in B-51. Come ask questions and prepare for the test. Here is the Review and Key
Pre-Calc – We’ve been working on the Chapter 5 Test. Afterwards we relaxed with some KenKen.
Algebra 2 – Talked about the time value of money. Very interesting and probably the one of the most important topics you’ll learn about this year. If you missed class today, you’ll need to check out the TVM solver on your TI calculator; I can help you with this, but you’ll need to come see me (or email me). We started an in-class activity that we’ll finish up tomorrow. All late work due tomorrow.
Pre-Calculus – We had a lot of absences today (swimming, sickness, etc), so the test was postponed until tomorrow. Remember, all work is due tomorrow.
Algebra II – Finished up 6.7 and did lots of examples of solving equations with logs. HW 46 (6.7) due Monday 1/25.
Pre-Calc – Went over problems on the review. Found a mistake on my review key (theta for problem 2c is 239deg, not 121). Review Night tonight at 6:30 in my room. I have to leave at 8:20.
Alg 2 – 6.7 Richter Scale and Newton’s Law of Cooling (we’ll work more on this tomorrow).
Pre-Calc – Reviewed how to use calculator to convert between decimal degrees and deg/min/sec. Save some time and do these conversions on a calc. Especially for the review.
Here is the review and key. I realize there was a lot of converting between degrees and degrees/minutes/seconds. On Tuesday, I’ll show you how to convert on your calculators. The test won’t have as much emphasis on this skill.
As promised – sorry the pics are a little dark. You’ll need to rotate the pdf when it opens. I’ll post the Chapter 5 Review Key a little closer to Monday – I want you to take a shot at it on your own first!
Enjoy Winter Ball and the long weekend!
Alg2 – We’ll be talking about the Richter Scale next week. Stay updated on the news coming out of Haiti over the long weekend.
All late work due 1/22
Pre-Calc – All work due 1/22 (Chapter 5B, Chapter 5 Review, and your Legal Description drawing with area).
Alg2 – Introduced the natural number and the natural log.
Pre-Cal – Found area of a polygon by breaking it up into triangles. Law of Cosine is very useful. Legal Descriptions were handed out to all groups. We’ll be spending some of tomorrow drawing our plots and calculating acreage. Chapter 5 test at the end of next week
Alg2 – What a cool day in Alg2. Lot’s of chemistry.
Pre-Cal – Finished up some Law of Cosine intro with a couple examples. I will be sure to post hints to the story problems in 5.7 and 5.8 over the weekend.
ALG 2 – Sound Intensity. I learned about Owl City today (I always wondered who sang that one song…).
Pre-Calc – I tried to introduce the law of cosines today. Seating chart anyone?
