90th Post!!!!!
Mr. Max is at home sick today... :(
We are to be workin' on either:
1. Tessellation Assignment
2. Circle Questions (opitional, #1 - 39, random test sometime this week)
3. AM catchup
=================================================
December 20th
Ok I'm board and it's my last geo. class before Christmas break. I find some of the circle questions a tad difficult (fun though, I admit). I also realized that none of the circle "laws" are on the blog!!! I'll do that.
Cirlce Geometry
1. If a central angle and an inscribed angle in the same circle both intercept the same arc, then the central angle has a measure of twice the inscribed angle.
2. If a diameter or radious happens to intercept a chord at a perpendicular, then that chord is bisected at the intersection point. ***Converse is also true.
3. If a circle contains an inscribed angle such that the angle intercepts a semicurclaular arc, than the inscribed angle has a measure of 90 degrees. ***Cinverse is also true.
4. If two angles are inscribed in the same cricle and they both intersept the same arc then they are congruent.
5. If there exista a line tangent to a circle then the tangent line is perpenduclar to the radius/diameter at the point of tangency.
6. If a point exists in the exterior of a circle and two unique lines tangent to that circle exists through that point then the segments created fromthe points of tangency to the exterior point must be congruent.
7. "The sum of the measures of the interior Angles of a Polygon."
============================================
The notes on circles we did in class.
The pictures (accept weapons of math destruction) were created my myself using various programs. More are coming soon, just didn't have enough time before the holidays to create them all.

December 14/07
Today Mr.Max's was away so Mr.Buckner was our sub.
Our assignment is to work on Exercise 2 (in the circle booklet) all 36 questions. Next week we will be quized individually on a randomly picked questions out of the exercise. Also we are to work on the tessalation project which is Exercise 3 question 9. and if your done all that you can work on accelerated math.
Have a good weekend everyone. Hope you have all your christmas shopping done

December 4, 2007
Since yesterday was a snowday, Mr.Max gave us an extension on accelerated math. The 43 objectives are now due at 5pm today.
Today in class we had a work period.
Tomorrow Mr.Max will be teaching us about finances. So he said it would be good if we figured out how many weeks are in a year and other stuff like that.
There is also tutoring after school with Mr.Max on Wednesdays till 5pm.
Hope everyone had a good snow day yesterday.
*****The scribe for tomorrow is Chev*****

November 30th
Hey today as all know Mr.Max was away, so Mrs.Turton was our sub for the class.
Today are assignment was to work on Accelerated Math. This is due to the fact that there are 43 objectives due on Tuesday December 4th. Hope everyone is somewhere near there.
Well since its a work period, I'll briefly discuss what the presentation this morning was about.
The presentation was on addictions. There were 3 guys who came to talk to us, Trevor, Steven, and Rollin.
They each shared some of their struggles with their addictions to alcohol and drugs. All had said that they remember sitting through these presentations when they were in high school and saying that they would never smoke or do that stuff. They also wished they had talked to their parents, school counsellors and teachers. They are here to help not to hinder.
They also said that is was like an illness of the mind that you bring on yourself. They all recall thinking that they weren't good enough, or they were like chameleons that would just blend in with which ever crowd of friends they were hanging with.
Rollin went through the loss of his wife and son, although now him and his son have a great relationship. Rollin can relate to what his son is going through in school and they have agreed to be best friends through all high school and talk about everything. Also while he was in his addictions stage he was involved in a biker gang. he was also attacked during his addictions due to gang membership. He was stabbed tried to commit suicide twice and lost everything, his house, car, everything, and yet he is still here to share his story. He is helping to make a difference in Winnipeg by coaching boxing, he recently opened up a center that anyone can go to. Tune into APTN on December 26 to see one of his moving boxing shows in which he helps street kids. Rollin has been sober and drug free for 5 years now.
Trevor was introduced to drugs when he was in grade 7 or 8 and as he recalls he was high when he attended a presentation like this in high school. He dealt drugs on and off. He hates rehab centers. He went through many in just a year. He is glad that he changed his way from alcohol and drugs. He has been sober for a year and a half now.
And last but not forgotten is Steven. He has always felt different. One day his mom pointed out a man at a 7-11 that looked feminine and said that he was "gay". Steven simply asks what does gay mean? His mom is like a guy who is attracted to men. Now Steven had always had trouble when it came to commitment with his numerous girlfriends he just couldn't commit. He would always be like "I'll try harder with the next one". He would quite often drench his pain and his sense of not belonging by doing drugs and alcohol. He started to deal it too. His life is now great and he has realized that he is gay, but it doesn't matter to him. Steven has been sober and drug free for 2 years on December 13.
Even though they didn't know each other before the 12 step recovery program, they all had many things in common. All three of these men went through many hardships. They lost everything, they felt alone, lost, even rejected at times. They all feel in to the trap of drugs and alcohol addiction.
Now they are all happy to feel free for the first time in years. Even though they said they'd never get into any addictions it still happened. Peer pressure, is one of the main reasons people get into these situations. As they said its easy to say that you won't but harder to actually do.
Yeah i know its long and slightly repetitive but I found the presentation to be good and motivating.
**** REMEMBER: 43 objectives are due on Tuesday December 4th*******
Good luck and have a great weekend everyone.
P.S. I'm not sure who scribes on Monday

Lesson: Exponential Functions (non-linear functions)
"Hole puncher, where are you!? It usually comes to me when I call it."
- Mr. Max :)
We started with Mental Math. #17
- All Hallow's Day/All Saints Day (Nov 1) is after All Hallow's Eve (Oct 31)
25 objectives due thursday at 3:40
With this information we came up with our equation based on the question (get my drift?). We came up with I(d) = 100(0.97)^d. We chose this equation (out of the possible two/four) because it is a.
Where the 0.97 is the percentage of sunlight you see one meter below the surface of the water.
With that equation we entered it into our calculator/graphed it (substituting I(d) for y and d for x), and got something very similar to what Max has on the slide. We determined that a was the correct answer after observing the graph (at 0 meters below the surface we received 100% of the sunlight, at one meter 97% of the sunlight was showing through, at two meters we were able to see 94.09% of sun rays).
This slide is the second example. I'll 'retype' the question since you can hardly see it in the picture.
"Early in the 1900s, an airplane manufacturer was able to increase the time its airplane could stay aloft by constantly refining its techniques. Using a graphing calculator, determine which exponential equation best models the data."
With this question we are given a table with 'years after 1900' and 'time aloft'.
With the green on the slide Max isolated exponential equation and wrote "do regression!", so that's what we are going to do (with our calculators... in point form because this post is beginning to grow like the bunnies).
- Determine which piece of information/variable is dependent (y) and independent (x). In this case 'time aloft' would be dependent so it will be labeled L2. (likewise the independent variable would be L1).
- On you calculator enter your information in the stat plot (If you don't know how/forgot go to 'the old math blog' or :chevy:'s post... apparently. This is also the top left clip on the slide). You might want to turn on that stat plot also.
- After you have your plot you could use zoom 9 or the window settings that are on another clip on the slide above. There you have the plot (right above the window settings).
- To draw the exponential regression (trying hard not to call it linear regression), go to STAT, CALC, 0:ExpReg.
- You end up back at your home screen. Press L1, 'comma', L2, 'comma'. To get the Y1 (as illustrated on the slide) go to VARS, Y-VARS, 1: Function, 1: Y1, Enter.
- ENTER, and you have your a and b variables which should tell you your answer.
- To see the regression simply go back to your graph and 'see' it.
------------------------------------------------------------
All info. came from inside the classroom and out of my keyboard (accept for pascals triangle which is a link in itself).
A point of interest... you can never have zero light. There will never be perfect and complete darkness.
People seemed to think my cartoon on my last post was pretty good, I'll give yea another one (which will likely end up as my signature with a smiley face just below it).
Which variable is dependent and which is independent? Where is the title for that matter?
:)
- Mr. Max :)
Things from mental math:
x - linear (no curve)x^2 - quadratic (one curve)
x^3 - cubic (two curves)x^4 - quartic (three curves)
x^5 - quintic (four curves)- All Hallow's Day/All Saints Day (Nov 1) is after All Hallow's Eve (Oct 31)
- 7 months have 31 days
Homework Check for pg A-7 to A-9
Exponential Functions
This slide is the summary notes for the lesson (exponential functions will always be in the form y=ab^x), and how exponential functions should generally look (rabbits multiply quickly over a certain period of time).
This slide is of your first example (hope you can read the example). We did two examples today. This one is about the intensity of light at a certain distance below the surface of a pond.
"You are a little frog sitting on a lily pad basking in the August sun. Something happens that the lily pad is pulled out of underneath you, and you find yourself a meter under the surface of the water."
The point of that was to 'illustrate' how the intensity of the light is less as you go deeper into the pond. If you were pulled a meter under the water you still see a lot of light around you because only 3% of the light was lost. We caught on quickly to the obvious - the intensity of light at the surface of the water is at 100%.
With this information we came up with our equation based on the question (get my drift?). We came up with I(d) = 100(0.97)^d. We chose this equation (out of the possible two/four) because it is a.

Friday October 26th
Today Mr.Max was away, so we had Mr.Richer as a sub. Today we worked on accelerated math and on the assignment that is due on Monday.
HOMEWORK: Student Exercise Questions: Page A-8, Exercise 2, 1-3, AND Page A-9, Exercise 3, 1a-f. ALL DUE MONDAY.
How to get to the Word Problems folder:
1) go to my computer
2) then open Rsfiles
3) open the coursework folder
4) go to the math folder and open it as well
5) then go to our class which at the moment is the second folder (Applied Math 30SA-1)
6) then you should see a folder which is labelled "word problems". Open it.
How to find the Vertex of a Parabola:
1) graph the parabola on your calculator.
2) press 2nd, then Trace.
3) then choose either minimum(cup-shaped) or maximum(cap-shaped) and press enter.
4) your screen should now show you graph again. at the bottom it will be asking you to go to the left side of where you think the vertex is. Do so with your arrow keys and then slecting enter when you are on the left.
5) now it will ask you to go right of where you think the vertex is. Do this the same as step 4 except you go to the right.
6) after you've hit enter to finalize your point in step 5, you then move your cursor to where you think the vertex is and press enter.
7) the correct vertex should then appear at the bottom of the screen. It will also state whether you used maximum or minimum.
Hopefully this helps.
*Remember that you should have 25 mastered accelerated math objectives by Wednesday October 31.*

Tues Oct 16th Math Class
Starting class today, we did mental math. When we finished, we corrected our homework from the weekend.. page A-4 questions 3,4,5. During the correction, we noticed that any quadratic function has infinite domain. This means the parabola will keep getting wider.
The answer key is found on the Rsfiles (J:) drive, Coursework, Provincial Math Booklets, S3 Applied.
Tomorrow, we are working on the Jane's Garden spreadsheet problem on page A-6. So, it is necessary to create the same spreadsheet with the appropriate columns on Excel.
For homework, make sure you're done or ready to scan accelerated math objectives 21-31 by the end of the day! If you're having difficulties with the word problems, you can recieve examples on the Rsfiles (J:) drive, Coursework, Math, Applied Math 30SA, Word Problems. Then, click on the subject that you need help on.
Wednesday's scriber is Jason.
