Period+A+September

Sept 22 Problem 2.4 - There are 2 sets of data in Problem 2.4 - one with Movie Theater and one with Amusement Park - each one can be used with the attendance data. Calculate slope for every 1% chance of rain - not for 20% as shown in the table. Try to write the equation and you can send me a quick email/call and see if you are correct before you carry onto question B. Otherwise I will post the equations on Thursday along with the answers so you can check your work. ACE 25-32

- answers will be posted on Thursday so you can check and ask questions.

Open both files to check your ACE work - with a color and note any questions/problems.

**Sept 24 Please check previous work with answer files from above.**
1) 3.1 in text: Recall the formula for area- length times width for a rectangle What is area? If you know the area of a rectangle, how can you find possible widths and lengths? Example if you know the area is 100 cm3 what could be the possible lengths and widths?

If you know the area is 100 and the width is 8 what is the length? Read over the introduction to the problem - lots of land -try some using guess and check - do you notice any patterns.

Now try A and B - both involve a table and a graph and seeing patterns Can you answer these in your mind as you work: Is this linear? If I gave you a width can you find the length if you know the area? Are the graphs similar? Would they cross the y -axis or x-axis? Do you see an overall pattern between width and length?

Answers will be posted on Monday so you can keep, you may send to me and check in are you understanding, need clarification or okay? Please send a quick email so I can track you.

ACE review questions starting after Investigation 3 (1,2,12-26) Answers posted on Monday.

=__Sept 28 Monday__=

1) Please check work over carefully using the following attachments. Please use a color to check so you can easily see problems you may have had when we return. Check ACE homework: 2) Problem 3.2 Working on Problem 3.2 Think of these as you look at the problem and getting started. What is area and how is it calculated? How do you find the area of a rectangle? If a rectangle has an area of 100 and length of 8 what is the width? Think back to the lots problem in 3.1 (look back as needed) For the inverse variation equation we use k as a variable so y=k/x - this would not be linear Read through the following link: [|Inverse Variation] Complete A,B,C - ask questions as needed via email or phone

3) Answers will be posted on Wednesday 4) ACE homework: (3-9, 27-31)

=September 30 - Wednesday=

1) Check Problem 3.2 - note any questions

2) Check ACE homework - please note any questions/problems

3) LAST PROBLEM OF THE BOOK 3.3 Getting Ready: Have you ever split the cost of something with someone? In this problem you look at a situation of splitting costs - something with a fixed cost. Read over the problem.

Problem A - if you can' some up with the equation think about making a table of values -(number if students, per-student cost) Problem C - if you double the independent variable in an inverse equation, the dependent variable is cut in half. Remember we are thinking about 3 possible equations for inverse variation: y=k/x or xy=k or x=k/y - think about these in terms for the area of a rectangle

Work on A,B,C,D - answers will be reviewed next week in class

ACE:10,11, 32-39 -will check in class next week

Short check up quiz will be Oct. 11
