Ch 10: Conics

2008-05-08T08:35:00.000-04:00

Here we are at the end of the road. Only one thing left to cover: CONICS.
What are conics? Conics are cross sections of a cone.
If you take a cone and slice it at different angles you will see the 4 different conic shapes: Parabalas
Circles
Elipses
Hyperbolas
You will complete a Webquest to explore and learn about conics.
Have fun as you explore the world of conics.
Here is the link to the webquest.

Please post a response to the following questions:
1. What are some of the ways Exponential and Logarithmic Functions are used in the "Real World"? Please explain your answer in detail.

2. How does the properties of exponents we have learned in the last 2 chapters help us to solve exponential and logarithmic functions? Or do they have no bearing on the subject?

Please include only your first name and last initial in your responses.

Matrices - The Math Behind the Code

2007-11-14T11:44:00.000-05:00

In this unit we have discussed how to add, subtract, and scalar multiple matrices.
Then we learned how to multiply matrices, find the determinate and use determinants to solve systems of equations(Cramer's Rule).
Now we are learning how to find inverse matrices. We will use Inverse matrices to solve systems of equations and to write secret codes.

We completed a Texas Instruments activity .

Students will be creating their own secret coded messages and sending them along with the key to the teacher.

For extra credit, students will complete a webquest. They will not be working as groups but as individuals.

Solving Systems of equations

2007-09-30T19:31:00.000-04:00

What are the 3 methods for solving systems of equations?

Your group needs to click here to complete the first webquest assignment.
Each person on the team will complete the practice problems and answer the questions on their own sheet of paper and turn them in to either Ms. McGuire or Ms. Zomer.

Then the group will click here to complete the second assignment. This webquest requires the group to work together and complete a series of tasks and create and end project. It gives you the choice between a poster or a power point presentation. The groups will begin presentations on Tuesday, October 9. The ruberic for grades is given on the website.

September 11

2007-09-11T09:56:00.001-04:00

Tell me where you were September 11, 2001. What do you remember? What does that date mean to you?

I was a stay at home with 2 small children, ages 1 and 4. We always kept the tv on PBS or Nickelodean. My Husband called and asked if I had been watching TV. I told him of course, and he said "Real" TV. I turned over to a regular network and was shocked as I watched the 2nd plane hit the buildings and then watched as the buildings collapsed. I was in total shock and then fear swept in. Would they start aiming planes at Atlanta? We have the largest International airport in the world. Could we be next? We mourned with the country in the days, weeks, months to follow.

My Brother in law decided that he needed and wanted to do something. he chose to enlist. He ended up in the National Guard as a medic and was sent to Iraq in May, 2005. In October, 2005, His humvee hit an IED. He was sent to Ramstein Air Force base and under went brain surgery and part of his temperal lobe removed to stop the bleeding. He came back to the states and was at Walter Reed Hospital in Washington DC.
While he was in the Hospital he met President and Mrs. Bush when the President came by to personally present to the injured men with their Purple Hearts.

September 11, 2001, changed our lives forever.

Welcome to Ms. McGuire's and Ms. Zomer's Informal Algebra 2 class. We hope you all have had a great summer and are ready to get started in a new school year. We have a lot of new and some old things to share with you.

Let's begin with what you will need for class. This year you will be required to keep a 3 ring binder. I would recommend dividers to keep notes and homework seperated. I would also recommend keeping a pencil holder in your notebook. You need to use pencils in class, NOT PENS!! Also make sure you have plenty of paper.

Something new we are going to do this year is to keep a math journal. You can do this 1 of 2 ways: you can either keep a notebook in class or a section in your binder or you can keep a blog online. We will go over blogs more in class. If you choose to keep a paper journal, you can keep your journal in class. I will give you a place to store them.

Calculators are a must for class. You can get one at Walmart for about $10 that will do what we need you to do. Any scientific calculator will do. A good one is the TI-30x. A graphing calculator would be nice but is not required. Good graphing calculators are the TI-83 or TI-84.

We will be using this blog to help post homework and other news that you may need, along with some help.

I look forward to working with each of you this year.
