This morning we were told good/bad news.. our exam schedule is out! The first part for the Applied 30SA test is on the last day of school, January 28 at 10:40. Then, the second part is scheduled for January 31 at 12:50 pm. They will both be held in Mr. Maks' classroom.
In today's class we corrected homework questions for exercise 2&3 of interest and budgeting. The booklet answers can be found in the folder J:\Coursework\Provincial Math Booklets.
As for homework, we still haven't gone through our circle booklet so make sure it's done for next week! Most of Accelerated math is due on January 18 (50 objectives).

Today in class exercises 2 and 3, in the intrest booklet, had to be done for end of class.
To get the answers to all of the questions, certain formulas must be used.
The formulas are.......
1.Find intrest= I=(P*r*t) Intrest=(Principal*rate*time)
2.Find Principal= P=I/(r*t) Principal=Intrest/(rate*time)
3.Find rate= r=I/(P*t) rate=Intrest/(Principal*time)
4.Find time= t=I/(P*r) time=Intrest/(Principal*rate)
To get the answers to all of the questions, certain formulas must be used.
The formulas are.......
1.Find intrest= I=(P*r*t) Intrest=(Principal*rate*time)
2.Find Principal= P=I/(r*t) Principal=Intrest/(rate*time)
3.Find rate= r=I/(P*t) rate=Intrest/(Principal*time)
4.Find time= t=I/(P*r) time=Intrest/(Principal*rate)

Blogging Self-Assessment
As we near the end of this course, I'm looking for your assistance in generating a 'score' for your contributions via the blog for the semester....Specifically, and with respect to the photocopied handout entitled, "Blog Scribing in Room 204", use these questions to help you formulate in your own mind an idea of what mark you deserve. I'll hand out a rubric in class to help you finalize an actual score, with weighting....
1. Did you blog when you were supposed to? (within 24 hours?), (and every time you were supposed to?)
2. Do your posts contain relevant screen shots from my Sympodium, incorporated in a meaningful way?
3. Have you ever commented meaningfully to another student's post? Were you gracious, decent, sincere, and timely?
4. Did you just do the bare minimum or did you actually take some time to contribute something worthwhile and meaningful to your classmates?
5. How is your spelling / grammar on the blog? Would your ELA teacher approve or disapprove of your language presentation?
6. Do you think I might have any constructive criticisms of your efforts? If so, consider these accordingly...
7. Did you ever contribute a meaningful image, link, thought, idea that was beyond the scope of classroom discussion. Did you ever exceed the expectation of your responsibilities to your classmates?
The only way that I believe that you should consider awarding yourself full marks in this category of your assessment for this course is if you can honestly and sincerely reflect upon these questions and award all the marks available as a result. Some of you deserve these marks, but some of you certainly do not. The rubric I hand out in class will help you determine an actual score....
Comments here might be appropriate if you have any reflections to share about this process

We started off the class with mental math mr. max added our mental math marks and our extra 5% from the test
*note*53 objectives due by the 28th
*for tomorrow ex# 2 budgets invastments
ex# 3 budgets and investments
In this class we had time to work on our our budget and investment sheets
we used the spread sheets on excel

Tuesday Dec 20
Today in math Mr. Max showed us " The one sided piece of paper" He made a 3d type object. He then had Schure colour the one side of the paper with a green marker and that proved his theory of the one sided piece of paper.
Next Mr Max showed us the Klein Bottle. I thought it was really neat, there is no inside and no outside.
Then Mr Max gave us a puzzling problem. That made us really think why the rectangle was bigger than the other the diffrence was only 1, and still no one could figure it out. He gave us hints to. He said we could think about it over the break and try and figure it out.

Have a great christmas break everyone!!

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 17
Today we started with Mental Math. It was probably the most toughest one i did! If you did good on it well congrats to you!
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
We haven't yet set a date for when the tessalations (number 9) is due yet but sometime this week....... So get busy and get it done!
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Mr. Macs is checking everyone's budget assignment if you did not finish yet.
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Today Mr. Macs is teaching us about "Simple/Compound Interest"
Simple*
->Interest is calculated EXACTLY once
Compound*
->Interest is calculated continually, at the end of every compounding period
Interest: (Think two perspectives)
An amount of money generated through the use of 3 variables.
>Principal Amount (P) $
>Interest Rate (r) %
>Time (t) years
Simple:
I=P.r.t (Interest (by it self))
Compound:
A=P(1+r/n)^n.t (Amount (Principal plus interest))
P= Principal ($)
r= Rate (%)
t= Time (years)
n= number of compoundings per year
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Everybody should have wrote the example down that he gave us so i am not going to type it all out but this is it summed up:
In the 5th year Bob's total value of his investment is $1276.29
This is called the compounded amount(Interest was added (compounded) to thw principal each time).
This way was using the simple way and finding out his earnings for each year than adding them on to the next.
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
An easier way to get the same number would be: (compound way)
A=P(1+r/n)^n.t
=1000(1+0.05/1)^1.5
=1000(1.05)^5
=1276.29
HOLY!!! Did you notice that this =1000(1.05)^5 looks like the equation y=a.b^x!!
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Another way you can find this answer is also using excel!! (you can use excel for so many things!)
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Well that's what we did today!! I hope everyone had a great weekend and only 5 more days of school left!!!!! YEAH!!
For tomorrows blog Semba you are the blogger!! Have fun!
