Emmas missed days NOV 25 andNOV 26

Arithmatic Sequence: When you adved or subtract

Geometric Sequence:When you multiply or divide

Recursive:next term is based on the previous term

t9=9*?

*You can go on edline to get the graphs or you can make your own
*We also got our project for Sequences called make you own caffeine

then we got to work

NOV 27 Blog-Emma

Today in class we did tutorial 6.2 Modeling Using Sequences.

Time-you always have to start with 0.

Descrete Data-the dots do not connect.

Maintenance level-The amount of the substance iilizesr stabn the blood eventually levels off.
or stabilize

Assignment:pg 270 #1, 4, 5

November 24th Blog

Today in class we learned about sequences.
1) Arithmetic Sequence- the sequence where the next term is found by adding/subtracting
2)Geometric Sequence- the sequence where the next term is found by multiplying/dividing

Recursive- the next term is based on the previous term.
t9=t8 x 2

Explicit- the term is defined by it's position(term number)

t9=9 x _?_

t1 t2 t3................ t10
2 4 8 t10=2^10

The Fibonacci Sequence is: 1,1,2,3,5,8,13,. . . .

We also learned how to find sequences on our calculator:

Ex) Week Prize
1 t1 5
2 t2 10
3 t3 20

1)mode--->seq
2)y=
nMin= what the first term is called----->1
u(n)=recursive formula (*always* u(n-1))---------> u(n-1) x 2
u(nMin)=first term (where you start)-------> {5}

So, to find week 52 go to 2nd function window and change the tblstart=52

Sequences(new unit)
This new unit will talk about sequences....(obviously)
Today:
PYRAMID SCHEMES(Illegal)
Pyramid schemes can be made by anybody.Pyramid schemes are inherently injurious to consumers because as a mathematical certainty, they are doomed to collapse. As in the case of chain letters that require a payment, only the people at the very top make any money.


EX> 6
36
216
1,296......ect
Pyramid schemes exploit people. This with limited knowledge of business such as individuals who have little experience in direct sales.
Why would anyone join a pyramid scheme?
They are sold to people that are assured that they are absolutely legal...(THEY ARE NOT NOT NOT LEGAL)
These people expect money to come in later down the line or any sort of promised prize and they do not receive it. These people that start these are con artists.
EX...
Dear investor:
You will be a millionaire....!!!! send 20 dollars to me with this letter.I will send it out to 6 people who will send it to six others and so on. for every person sent to you will receive 5 dollars. this is how it will work:::
round letters sent responses total people
1 200 12 200
2 2400 144 2600
3 28800 1728 31400
4 345600 20736 377000
5 4147200 248832 4524200
6 49766400 2985984 54290600 $14,929,920.00
7 597196800 35831808 651487400
8 7166361600 429981696 7817849000
This here is how it would work out if 6% of the people responded to the letters.

some times these are really bad schemes and the people do not send out any money and they take 100% of the profit this is what happens in most cases..

today we went over examples 2 and 3 in our design & measurement booklet.
area is always m2 and volume is always m3.

in this example (ex. 3 from our booklets) its showing us how to find the surface area of a cylinder and the slant of the cone and the slant area of the cone.

Tuesday Nov 18

Today in class we got our new unit hand-out Design & measurements pretty straight forward stuff we need to be able to figure out in life. In otherwords useful math. Here we have an example of what can go wrong if you don't want to pay attention in math class.

A tad Tardy

TUESDAY NOVEMBER 10TH!!

Started the ol' class of with a hand in sheet that already has the answers on them. So that you can see the answer and see if you're doing it correctly.

We then took a gander at Remax and Action Realty websites to calculate the mortgages on homes around Dauphin.

DEFINITIONS

AMORTIZATION- amount of time required to pay off the loan

TERM- Length of the contract.

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~


THURSDAY NOVEMBER 12TH

Not much happened on Thursday. We looked over a mortgage tutorial sheet for a while and then the rest of the class was simply a work period.


~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~


FRIDAY NOVEMBER 13TH


Started the class of with Tutorial 4-6. We then received 2 Hand outs that will not be due, only for the purpose of practicing .

Then we cracked the ol' text book to page 191 on Renting and Buying.

Finished it off with the analysis of Renting or Buying a home.
