Ch 10: Conics

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.

Chapter 8: Exponential and Logarithmic Functions

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.

Homework Spring 2008 Blue 1st

Matrices - The Math Behind the Code

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

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.
