Periodic Functions

In the first part of class this morning we went over what we learned last class (Friday). After that we finished up about the role of Parameter B & the role of Parameter C. The pictures below are pretty straight forward on how it works & how to get it.

Okay, the picture above...I bet your wondering what does the 2 (or any #) in front of the X does!? It helps you find the period....Remember it's not the period it just helps you find it!

After that we went over are homework. Now, I give honors to the next scribe....and they are........ICKIE!!!!!

BOB

This unit was okay for me, it's pretty easy to understand....it's just that there are lots of formulas that you have to remember that I can have trouble with. With the formulas I remember them right now(well, i think so)...but when I get the test I sometimes just blank so then I forget the stuff that I have learn &/or studied. So, I'm hoping that I won't blank out on the test tomorrow!!! That's all that I can think about to write....GOOD LUCK EVERYONE!

Mortgages

Hey everyone! Today we started to learn about mortgages. In the morning class we just mainly talked about the pros & cons about buying or renting homes. The number one pro for buying or renting a home is the LOCATION!! In the afternoon we just talked about costs when purchasing a home.

If you’re renting these are some things that you should keep in mind:

1. You need to pay the monthly rental payments in advance plus probably one month’s rent in advance as damage deposit.
2. It is cheaper to rent a home in the short run than buying, but it doesn’t create any assets.
3. You need to know what is included in the rental payments. Example: are the utilities (especially water, hydro, heating) included? Is the home furnished…etc.
4. When renting a house, the rental payments will increase over time and you don’t create any assets. If you buy a house then the value of the house normally increases with time.

Non-financial factors to consider when renting:

1. When renting you might be restricted to your lifestyle. Example, you maybe not be able to have pets, or modify the home to suit your personal needs.
2. Repairs, maintenance, or property taxes you are not responsible for. Example, if the hot water tank needs replacing, the owner is responsible.
3. It is better to rent then buy a home if you only need the home for a short time. So then you can avoid the inconvenience and expense of reselling the home.

Now, we will look at the costs associated with buying and renting a home.

"How Much Can I Afford to Pay for a Home?"
Banks and other lending institutions have developed a formula that
allows you to calculate the maximum price of a home you can afford.
This formula is known as the Gross Debt Service Ratio, or GDSR.
According to this formula, anyone buying a home should spend no
more than 32% of gross income on household or accommodation
expenses, including mortgage payments, property taxes, heating
and condo/strata fees. The formula may be written as:

Question #1
Lucy Brown wants to buy a condo, but does not know how much money she
should spend based on her income. She earns $44 000 per year, and has saved
$9000 for a down payment. The property taxes for the condo she likes are
$1500 per year, and the heating costs average $90 per month. The condo/strata
fees are $180 per month. The bank will give her a 25-year mortgage at an
interest rate of 7.5%. What is the maximum price she can afford for a condo,
based on spending no more than 32% of her gross income on household and
accommodation expenses?
Now since there is so much stuff in the question just break it down into small parts like it is done below.

Once you have done that you can finish answering the question…..like done below.

I know that you are probably wondering why C/Y is 2. Well it is 2 because by law in Canada the bank can ONLY compound you twice a year!
After you calculated everything your Present Value will be $118,696.49 after 25 years. Plus you have to include the $9000 down payment that Lucy has saved up. (Showed below)




I know that you might be wondering what do some of these mean...right down below are some of the definitions.

1. Appraisal fees- The process through which conclusions of property value are obtained; also refers to the report that sets forth the process of estimation and conclusion of value.
2. Property survey- The process by which boundaries are measured and land areas are determined; usually performed by a land surveyor.
3. Insurance costs for high ratio mortgages- This is only for first time house buyers, you only pay 5% of it & the bank pays the rest.
4. Land transfer tax- A tax payable to the Provincial Government by the purchaser upon the transfer of title from a seller.
5. Interest adjustments- Extra proceeds going to an investor who submits a convertible bond for conversion to account for interest accrued since the last date of record for an interest payment.
6. Legal fees- A fee paid for legal service.

I hope you guys like my scribe post & I'm sorry if the pictures arent that good….but now I’m off on my choir & vocal jazz trip to moose jaw! I am honored to announce that our next scribe post will be by the one the only H20!!!!! YEAH.

Scribe Post

Hi Everyone! Sorry for it being late! The first part of class in the morning we went over our homework from last night. After that we had a warm up to our next topic in Probability “The Fundamental Principal of Counting.”

Warm Up….
Question # 1
Find the probability of flipping three pennies and getting at lest 1 heads.

The first penny would be either heads or tails; the second would be also heads or tails etc. The chance of getting either one on any of the pennies on the three times would be ½., because there are 2 sides to a penny.

*Remember to watch how the question is worded.
Ex. 1. Heads AND Heads AND Heads mean multiplied.
2. Heads OR Heads mean add*



Question # 2

How Many Ways

A.) The café special for lunch offers a choice between two main courses (hamburger or chicken burger) and three different drinks. The “meal deal” allow you to pick one each. How many different “meal deal” are there?
*2 meals times the # of meal deals = 6 diff. ways.

B.) What if they decide to throw in a choice of fries, spicy fries or plain chips. How many “meal deals” are there now?
*Now you add the fries, spicy fries & plain chips on.

*Now you just add the 3 more diff meals to the first two. Witch now = to 18 diff. ways.

Now this is what the warm ups got us warmed up for…….

“The Fundamental Principal of Counting”

If there are M ways to do a first thing & N ways to do second thing then there are M * N ways to do both things.

Ex. Any one of 4 ties can be matched with any one of 3 shirts, how many shirts & ties combinations are possible?
* 4 ties times 3 shirts = 12 diff. ways to find combinations.

What if there are also 2 different pairs of pants that can be matched with all the shirts and ties, how many different “outfits are there now?

Now you try……

1.) How many 4 digit #’s are there if the same digit CANNOT be used twice?

* The First # can’t start with 0.

2.) How many 4 digit #’s are there if the same CAN be repeated?

* The same rule applies here can’t start with 0.

3.) How many 4 digit EVEN # CANNOT be used twice?

















Well I think that is about it….I hope you guys/ gal’s understand what I wrote. The next scribe is…….Mercee

BOB-Matries

The first unit Matries wasn't that bad. I found it to be easy most of the time, but when it came to the word problems that is where I had a hard time. Other than that it wasn't bad.
Till next time bye for now!
