Hey hey! Today we started the day off by lokking at Mr Max's new calculator. Its pretty fancy, and he seems pretty excited about it. Next we did mental math. Mr Max. told us that he is going to spen these last few day going over review and such, so when we get back we can do the last lesson. He then let us go through old exams for practice. So then i guess thats it for the class.
See ya

Tuesday, December 18, 2007

Hey! so today mr max wasn't here... we were suppose to either make a formula sheet for the exam or work on questions from old exams.

December 17, 2007

Good afternoon. Today we started class off with mental math #26. We then corrected questions 3 and 6 from the personal finance review. Also today the topic of why we do mental math came up. The reason that we do it is to provide students with mental practice in computing basic number facts and combining mathematical operations which we could use in everyday situations in which it would be quicker to calculate it without technology or when technology is not available. Have a great day.

December 13 2007

Hey class mates,

Today we started the class off with mental math. After mental math we dicussed and went over the Bob and Carol question using the Statement of Net Worth spread sheet found in our applied math folder. Their total liabilities is $133,500, the net worth $115,500and the debt equity ratio is 29.00433. If Bob and Carol are in their 20's or 30's they are doing very well and if they are in their 50's or 60's then they would be doing not so well. We got a definition of liquidity which is the relative ease of converson to cash without loss of principal. We were assigned 2 questions from the personal finance review booklet ( #3 Maila and #6 Ralph ) they are both due for Monday. Use TVM solver or Excel. Tommorrow Mr. Max wont be here so you can work on these questions or work on the old exams for practice.

December 12 2007

Mr. Max did a homework check at the start of class, then we went over the the question (question 14) .



We then took some notes on debt equity ratio. The notes got deleted so I cant really put them on here. The formula for debt equity ratio is....

total liabilities-mortgage on principal ratio divided by net worth.



Our homework was to find out Bob and Carols D.E.R.

Dec. 10

Hey everyone! Today the whole class individually posted their answers from question 8 on the blog, and then everyone commented on each others answers and how everyone did the question. After Mr. Max started a new unit call "Personal Finanaces." Here is some of the stuff we did:



Tuesday, December 11

Today we started off with a mental math.

Mr. Max was really impressed with our efforts from yesterday on the blog. Other then a few constructive criticisms, he said over all he was impressed. Many people have to correct their grammar, everyone talks like they are texting, or on facebook. This is a very bad habit that people need to break before going on to post secondary education. We are losing our vocabulary by trying to use the fastest way to say something, without doing it properly. It is not just this class, it is people all over the world.


We did some personal finance questions on the Written Test of January 2006
Page 14, Question 13

Amortized
Amortize(v.) Total length of time that it takes to repay a loan
Amortization(n)
When you put in an interest rate on a spreadsheet you put it in as a decimal, but if you are using TVM solver, you put it in as a percentage.

Homework for tomorrow is Question 14 on the Written TestJanuary 2006, Page 15

Question #8 Antibiotics




This is how i did question 8 a and b.

Solution to #8

Part A:
Day 1: Take pill # 1: 500 mg

Day 2: 500*.75= 375 mg
Take pill #2: 375+500= 875 mg

Day 3: 875*.75= 656.25 mg
Take pill #3: 656.25+500= 1156.25 mg

Day 4: 1156.25*.75= 867.19mg
Take pill #4: 867.19+500= 1367.19 mg

Day 5: 1367.19*.75= 1025.39 mg
Take pill #5: 1025.39+500= 1525.39 mg

Day 6: 1525.39*.75= 1144.04mg
Take pill #6: 1144.04+500= 1644.04mg

Part b)
Day 1: Take two pills: 1000 mg

Day 2: 1000*.75= 750 mg
Take two pills: 750+1000= 1750 mg

Day 3: 1750*.75= 1312.5 mg
Take half a pill: 1312.5+250= 1562.5 mg

Day 4: 1562.5*.75= 1171.875 mg
Take half a pill: 1171.875+250= 1421.875 mg

Day 5: 1421.875*.75= 1066.41 mg
Take half a pill: 1066.41+250= 1316.41 mg

Day 6: 1316.41*.75= 987.3075 mg
Take half a pill: 987.3075+250= 1237.3075 mg
This is my question 8

Click on the picture to make it bigger if you can't see it.



Drug Question

a) b)





antibiotics

A) day 1 - 500

day 2- 875

day 3- 1156.25

day 4- 1367.1875

day 5- 1525.390625

day 6- 1644.042969



B)

First day- 2 pills = 1000 mg

second day- 1 pill = 1250 mg

third day- 1 pill = 1437.5 mg

fourth day- 1 pill = 1578.125 mg

fifth day- 1 pill = 1683.59375 mg



this solution works because it say for more than 5 days so if you they were picky and checked on the sixth day the level of antibiotics would still be 1262.695313 mg even tho you dont take a pill on the sixth day.

answers to the medication question

8.a)Day 1: 500mg
Day 2: 875mg
Day 3:11560.25
Day 4:1367.1875 mg
Day 5:1525.39 mg
Day 6:1644.04 mg

b)Day 1: take 2 500 mg pills= 1000 mg
Day 2: 75% of medication left= 750mg then take half a pill which=250 mg then it adds up to 1000mg. Just keep taking half a pill everyday and you should have 1000 mg of the medication daily. After 6 days there will still be 2 pills left so the medication will last 9 days.
This is my antibiotic questions answer.
The column that is named mg could also be called amount of drug in body..


A)







B)

antibotic question

For part a) I calculated the amount of antibiotics in the body at 8:00 am would be app. 1644.043mg.
For part b) I used exactly 6 days taking two pills the firsts, one and half the second, 1/2 a pill the third, one pill the fourth day, and half a pill on the fifth and sixth day.

Antibiotic Question

A)Day 1 - 500mg
Day 2 - 875mg
Day 3 - 1156.25mg
Day 4 - 1367.19mg
Day 5 - 1525.39mg
Day 6 - 1644.04mg

B)On the first day you could take two pills to give you 1000mg on the first and then a half of a pill for every day for at least five more days.

#8 homework

a) We got:
1st day --> 500mg 125
2nd day--> 875mg [500+(500-125)] 218.75
3rd day --> 1156.25 mg [500+(875-218.75)] 289.06
4th day --> 1367.19mg [500+(1156.25-289.06)] 341.8
5th day --> 1525.39mg [500+(1367.19-341.8)] 381.35
6th day --> 1644.04mg [500+(1525.39-381.35)]

*The green represents the amount released from the previous day, and the blue is the amount released from the corresponding day.

b) To achieve a level of at least 1000mg daily using only 6 pills, take 2 pills (500mg each) the first day and then half a pill (250mg each) each morning until all six pills run out. This is the work:

1st day --> 2 pills x 500mg each = 1000mg
2nd day --> [250+(1000-250)] = 1000mg
*in the square brackets the first 250 represents the amount of mg in half a pill, the information in the round brackets represents the amount of mg lost from the first day.
3rd day --> [250+(1000-250)] = 1000mg
4th day --> [250+(1000-250)] = 1000mg
5th day --> [250+(1000-250)] = 1000mg
This only used 4.5 pills, but the level of at least 1000mg was reached.

YAY Homework

There is many ways that you could interpret this question and i am sure there is a few ways i do not no.
For A I thought that you only take the 25% of of the pill that you take for the day and not take 25% off of everything that you have in your body from the days before to. So for my answer i got 2250 mg of antibiotic in the body after the sixth day. If you took 25% of of everything that you have in your body that day then your answer will be different.
For B I took 2 pills the first day and then I took only a half a pill a day for the next 5 days to maintain the 1000 mg a day need. This question is like the other so if you take 25% off of the full amount in your body your answer may very instead of taking 25% of off of just the pill you take that day.

drug question

So basically what I did for a) is took the pill on the first day, and then to calculate the amount in the body for each day I multiplied the amount of drugs in the body from the previous day by .75 because if .25 is eliminated that is how much will be left in the body. I then added the amount taken that day to figure out how much total drugs are in the body that day.

For b) i followed pretty much the same pattern as a). I started out with two pills on day one to acquire the 1000mg needed. I then took 1/2 a pill per day until day 9 which gave me my six pills and exacly 1000mg of drugs in the body each day.


#8 Pills

A) day 1____ 500mg
day 2____ 875mg
day 3____1156.25mg
day 4____1367.19mg
day 5____1525.39mg
day 6____1644.04mg

B) You could take 2 pills the first day. On the second day you could take 1 pill. The third day you could take 1. The forth day you could take your last 2 pills.

Infections and Antibiotics

500 mg tablets
term starts 8:am each morning
by next day 25% of antibitoic is consumed.

a) 500*.75= amount left over at 8:am next morning

day1= 500
day2= 375
day3=381.25
day4=158.20
day5=118.65
day6=88.99

b) 1000mg of antibiotic per day. within the rules of pills can only be taken at 8:am and no partial pills are needed.

day1= 2x500mg
day2= 2x500mg
day3= 1x500mg
day4= 1x500mg
day5= 1x500mg
day6= 1x500mg
taking in total 8 pills of 500mg will not allow the body's antibotic level to fall below 1000mg. over the six days you would have consumed in total 4000mg of antibiotics.

Question #8

a)

Days /Equations/amounts per day

1st day -- 500mg
2nd day -- (500+(500-125))= 875mg
3rd day -- (500+(875-218.75))= 1156.25mg
4th day -- (500+(1156.25+289.06))= 1367.19mg
5th day -- (500+(1367.19-341.80))= 1525.39mg
6th day -- (500+(1525.34-381.35))= 1644.04mg

b)

Day /Equations /Amount to take

1 -- 0.25(1000)= 250 1000mg
2 -- (250+(1000-250)) 250mg
3 -- (250+(1000-250)) 250mg
4 -- (250+(1000-250)) 250mg
5 -- (250+(1000-250)) 250mg


You should take 2 pills the first day and then 1/2 of a pill each of the following days.





8. a) Day 1- 500*.75= 375
Day 2- 375*.75= 281.25
Day 3- 281.25*.75= 210.9375
Day 4- 210.9375*.75= 158.203125
Day 5- 158.203125*.75= 118.6523438
Day 6- 118.6523438*.75= 88.98925781

b) Take two pills the first day then take half a pill for the next 5 days
8.a)(100-25=75)
500*.75=375mg-->Day 1
375*.75=281mg-->Day 2
281*.75=211mg-->Day 3
211*.75=158mg-->Day 4
158*.75=119mg-->Day 5
119*.75=89mg-->Day 6


8b) Day 1--> take 2 pills (375*2=750)
Day 2--> take half a pill (281/2=141)
Day 3--> take half a pill (281/2=141)
Day 4--> take half a pill (281/2=141)
Day 5--> take half a pill (281/2=141)
=(141*4) + 750
=1314mg

(By taking 4 pills in a period of 5 days)

Antibiotic Question

This is my answer for question 8. Aimee, Pauline and I worked on it together.

Question #8

The BOLD numbers are what is left from each day.
a) 1st day: 500mg - 375mg - 250mg - 125mg - 0mg
2nd day: 500mg - 375mg - 250mg - 125mg - 0mg
3rd day: 500mg - 375mg - 250mg - 125mg
4th day: 500mg - 375mg - 250mg
5th day: 500mg - 375mg
6th day: 500mg
* Add all the bold numbers to get the total amount of medication
Total = 1250mg (125 + 250 + 375 + 500)
* You loose 25% each day (125mg) so there would not be any left from day 1 abd 2 because that would be 5 and 6 days. The pills only last 4 days. So therefore you only count day 3, 4, 5, and 6.

b) 1st day: 2 pills (1000mg)
2nd day: 1/2 pill (250) 750mg left from last day (750 + 250 = 1000mg)
3rd day: 1/2 pill (250) 750mg left from last day (750 + 250 = 1000mg)
4th day: 1/2 pill " "
5th day: 1/2 pill " "
Total amount of pills = 6 (bold numbers)

She would take 2 pills the first day and then take a half of a pill each day after that, to maintain a 1000mg of medication.

Answers to Question 8



I figured instead of taking away 25% it was easier to find the percent of each number such as 25% of 500 was 125. This way it made it somewhat easier for me to understand.

Fractals

Homework check! Make sure you do the homework because Mr. Max finds the need to weigh them rather high.

Last day of Sequences... Today Mr.Max is going over the homework. Questions 6 and 10.

6.



homework for the weekend - question 8 and finish question 14 too.

Alsoooo Mr.Max handed us out Applied Mathematics Standards tests for us to look at. Very nice of him to do that. They willl be very useful to us i think.

Thursday, December 6, 2007

Hey,
So we started off the class with mental math. He then went around the room and did a homework check on question 15 on our Sequence review package (Murky Island bears).

If you don't have excel on your computer at home Mr, Max recommended using.......google docs and spreadsheets (docs.google.com)
Next we corrected question 15





Above is an example of a fractal

I don't know if this website will help you any but it looks like Mr. Max created it even the writing looks the same!

Hey, so today I found out i was scribing an 1 hour into class. So that is why you should always look who is scribing at the start of class. We handed in our baseball question after mental math. Then we had a homework check on the driveway question. He said to never round a number in a deep question like this one and anouther thing to keep in mind is to buy stuff in whole units. He showed us how to use GST and PST on the driveway question.

The answer for method one without PST and GST 8932.00 and the second method is 11381.72.
