Monday, April 27th

3 Parts to Your Work Today:
1.  Work on the new CK12 assignment, getting 10 right.

2.  In your textbook:  page 486 #6-8, 14-19, 26-29

3.  Write a one-paragraph essay explaining how Moore's Law, as explained in the Great Falls Tribune article last week, relates to the equation for exponential growth  y = yo e^(kt) that we learned in the last unit.

After getting our book assignments corrected, we will watch:

MathDoctorBob's Math-Filled Heart!    (end the video at 3:50, ignore the last part)

The French Did it Right!   (watch first 8:00)

A different Approach: a Rose by Any Other Name

Now look at the chart that starts on the bottom of page 477 and continues on to page 478.   Use this chart and graph any rose, any lemniscate, and any limacon on page 480 #8-17.  (Total of 3 graphs are due Friday)

Monday, April 20th (and beyond...)

Okay - we are still putting off trig identities in hopes of a couple of weeks where most students can be in class.  If that doesn't happen, I will get the technology needed put together to record my lectures on the smartboard and we will barge ahead anyway...

For now, we are going to cover a topic that I have skipped the last few years due to a lack of time.  But it is a topic that is listed in common core, is tested on the MCTM math contest in Havre, and has merit.  Just due to a lack of time, I have chosen to cut it the last few years.  However, polar coordinates is a topic that I think can be learned independently with some success.  Remember to search for your own videos on Youtube, Partrickjmt, Kahn Academy, etc... if you struggle.  Also don't forget you can actually "read" your math textbook as well -some of us have lost the ability/desire to do this.

Your first assignments are as follows:

MONDAY
Log into CK12 (using your fairfield.k12.mt.us account) to accomplish the following
** "Read" the material on Plots of Polar Coordinates
** "Watch" the video on the same material
**  "Practice" on the assessment until you get 10 right
** "Read" the material on Distance Between Two Polar Points
**  "Practice" on the assessment until you get 10 right

(Relevant book section:  9.1)

TUESDAY
Complete the following book assignment:  page 470 #10-24  (also find the distance between the points plotted in #11,12;   #13,14;    #16,17;    #19,20

WEDNESDAY
No assignment - all students gone on legislature trip

Tuesday, April 14th

For continously compounded interest:
1.  Find the value of a $20,000 investment after 15 years of growth at 8.4%.

2.  Find the value of a $250,000 investment after 25 years of growth at 6.5%.

3.  How long would it take $50,000 to grow to $150,000 at 7% APR?

4.  What is the "effective" APR of an accounting growing at 5% and earning continuosly compounded interest?

5.  Assuming the half-life of carbon-14 is 5730 years, how old is a pertified tree that now contains 3.5% of the carbon-14 that was present while it was alive?




6.  An organism contained 15 grams of the carbon-14 isotope upon death.  How much carbon-14 will remain in the organism (if preserved) after 100,000 years pass?


Do the following book problems:
page 643 #31-36

Monday, April 13th

Don't forget 3-minute memorizing quiz was scheduled for tomorrow! Will do at the end of the period.

Assignment due Tuesday:

page 639 #16,19,20,23,26-30,36

page 643 #26,28,30 

page 617 #25,26,28

These 2 problems:   (need to solve for a variable other than "A" in the compound interest formula)
1.  How long would $10,000 need to collect monthly compound interest at 9% APR in order to grow to $25,000?

2.  What interest rate would be required for $5,000 to grow into $8000 after 8 years?   Assume quarterly compound interest.
