Journal #9

    Journal #9 Statistics Due Friday May 2nd




              For this journal you will collect your own data. Come up with a question to ask some of your peers and/or family members. (Example: How many pets do you have?, How many siblings do you have?) This has to be a question where you will get numerical data and you must ask at least 10 People.

              Once you have acquired all your data find the mean, median, mode, and range. You need to also represent the data in either a dot plot, box plot, or histogram.

Journal #8

    Journal #8   Due March 21st   **Your journal must be at least 150 words**


Who developed imaginary numbers? Do a little research to find out why imaginary numbers started.  Why do you think mathematicians would develop imaginary  numbers?


      Solve the following problem for the two values of x. 
                              (your answer should include the number i):


                                 -4x^2 + 8x -10 = 0


         **Remember ^ means squared.

Journal #7

Journal on Factoring


For Friday 3/7 your journal is on the following:


You have been given the quadratic equation: 

if you cannot see the photo above the equation is: y = x^2 + 6x - 7

* ^2 means squared *

Please solve this quadratic using both FOIL(factoring) and complete the square. How do these two method compare? Are your answers the same? Is one method more useful than the other? Please support your answer with mathematical examples.




**Remember your journal must be 150 words**

Introduction to Quadractic Equations

February 25th, 2014 Homework

If the video does not play you can also find it at this link:

All of the examples in this video can be represented by a quadratic equation. We will begin discussing and learning about quadratic equations in class tomorrow. 

**Be prepared to answer questions about the video in class tomorrow.**

Extra Credit Journal

The following journal needs to be at least 200 words and is due on Januray 29th.

Geometric and Arithmetic Sequences:

Compare and contrast geometric and arithmetic sequences. (What do they have in common? How are they different?)

What is different about explicit and recursive formulas? Why do you think we write both? Is one more useful than the other? In what situation would it be best to use a recursive formula? In what situation would it be best to use an explicit formula?
