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.

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!

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

Thursday, December 13th

Today in class we had a work period to work on our budgeting assignment using our spreadsheets.

Tomorrow Mr Max is away so we will have a sub in. This mean Mr Max will not be here to check out budgets, so the last day for budget checking will be on monday.

Today we recieved the booklets on circles. The deal with these booklets is that we don't have to do all the questions in Exercise 2, but we have to KNOW HOW to do all the questions. Mr Max said he would be checking by getting us to come up and do random questions from the booklet for him.
The only question from Exercise 3 that is assigned is question #9.

Mr Max also said that he will be assigning accelerated math soon**

December 12

Today was a work period to work on our budgeting booklet Mr. Maks has assigned for us. Today he taught us how to calculate annual property tax and annual home insurance is order to answer some of the questions.

Here is how to calculate property tax along with an example:

You multiply the value by how many mills then divide that by 1000.

eg: The home is assessed for property tax purposes at $30,000, the mill rate is 61 mills.
$30,000 x 61/1000= $1830

Here is annual home insurance along with an example:

You divide the value by 100 then multiply that by the cost per $100.

eg: Home insurance based on a home value of $50,000 at a cost of $0.62 per $100.
$50,000/100 x 0.62= $310

As a class, we also discussed the fact that facebook has been blocked in our school and how upset people are. Many classmates had person opinions about this subject and many were upset.Many caim that it is a important communication device that is a very important and useful tool in their everyday life. There is some talk that the facebook homepage will be unblocked and as of now, everyone is hopeful.

Tomorrow the scriber is "Patzer."

Today is Day 1, which means long blocks. We started off by doing mental math. Mr.Max made a clear note that he dislikes facebook...but yet has an account. I dont get it it? Haha! We then made spreadsheets for budgeting.
Today we learned how to turn on all formulas on a spread sheet and this is how:
All you need to do is press the control key and the tilde symbol(the key right beside the number one). Your spreadsheet will now show you all of the forumlas you have entered into it.
We all have our spreadsheets figured out and are now working on 4 other budgeting problems. We dont have a certain due day yet but we will shortly.
I'd like to give a happy reminder to everyone that there is only 14 days till christmas...YAY!
The scribe for tomarrow is Minish. Have a Great Day everyone!

First of all, today was Day 2, short blocks. We started off with mental math.
~Just something to do-- look up "Fisonacci" on wikipedia and search the patterns he created.

We started a new unit today- Monthly Budgeting. We started to create a spreadsheet to help with the problems in the package that Mr. Max gave us on Thursday. We didn't get very far in this unit today because class was almost over. So Mr. Max said we will continue from where we left off tomorrow.

If my scribe was "cheap".. it is only because I didn't have much to work with. Sorry if it didn't help with much homework.

Todays Class was an interesting class. First, it was Day One which means that it is long blocks. We came into class and Mr. Max said that we weren't going to have a mental math, instead we had to take wooden blocks and we played the "Tower Game". The tower game is a game where there are three rows and you have to move the tower of wooded blocks to make the same tower in another place. But you can't have a bigger block on top of a smaller block. For example:
1 block = 1 move
2 blocks = 3 moves
3 blocks = 7 moves
4 blocks = 15 moves
5 blocks = 31 moves

We tried to figure out how many moves there would be for the amount of blocks we had, for the majority of the class. Then we got on a topic of billionaires. We had a discussion about are veiws of billionaires and if they are selfish or not. Then for the remainding of the class we had to research "The Bill And Melinda Gates Foundation". There was no homewrok assignment.

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.

Good morning everyone!


In today's class Mr.Max talked to us about circles again. He explained about which shape we would get if we "cut" a cone using a "razor blade". The following page Mr.Max made during class should explain what I mean to say better.


If a straight horozontal cut is made the shape made should be a circle.


If a diagonal cut is made, the shape should be an elipes (oval).


If a vertical cut is made with a slight slant, the shape should be a prabola.


If a straight vertical cut is made, the shape should be a hyperbola.




The equation used to create an image of a circle or an elips is
(x)^2+(y)^2=(r)^2
The center of the circle will always be at the origin (0,0), unless you move the center point. You do this by using (h,k) ((h,k) is the center of the circle).
The equation you would use will than be (x-h)^2+(y-k)^2=(r)^2
