Part 1: Newspaper Page

You will create a newspaper page called “Math News” explaining properties of exponents. Use the template below and the skills you learned about in Lessons 3 – 6 to help you as you complete this part.

·  Each article needs to contain at least two to three complete sentences, but can contain more if needed to fully explain the concept. Make sure all sentences are written in your own words and are not copied from the book, Blackboard, or another website. Sentences not written in your own words can be considered plagiarized.

·  Each article needs to contain an image showing how to solve the given examples below using the concepts from the article. ALL WORK must be shown for each part of the examples.

On the top of your newspaper page, you should put the title, your full name, and your student ID number. Please see the Newspaper Page Template below as a guide for how this should look.

Include an article on each of the following concepts:

·  Zero and Negative Exponents: What does a zero exponent do to a number or variable? What does a negative exponent do to a number or variable?

·  Scientific Notation: Explain scientific notation, how to convert numbers from standard form into scientific notation, and how to convert numbers from scientific notation into standard form.

·  Multiplication Properties of Exponents: Multiplying powers with the same base, raising a power to a power, and raising a product to a power – explain what happens in each of these properties.

·  Division Properties of Exponents: Dividing powers with the same base and raising a quotient to a power – explain what happens in each of these properties.

****Make sure you review the rubric for this part so that you are including ALL necessary information and images.

Part 2: Error Identification

For Part 2, you will identify errors found in each of the problems below and then correctly solve them showing all of your steps and work. Use the skills you learned in Lessons 9 and 10 to help you as you complete this part.

1.  Tom’s farm had 124 cows in 2005. The population of cows grew by 4% every year. Write an equation to model the number of cows. Find the number of cows in 2011.

Given Answer:

Let x = number of years since 2005 y = 124 * 4x

Let y = number of cows at various years y = 124 * 46

Let a = number of cows in 2005 y = 124 * 4096

Let b = the growth factor y = 507904

y = a * bx In 2011, the farm had 507,904 cows.

y = 124 * 4x

2.  Jenny is given $5000 at age 5. Her parents place it in a bank account earning 7% interest compounded quarterly. Write an equation to model the amount of money in the account. Find how much money Jenny will have at age 18.

Given Answer:

Let x = number of interest periods y = 5000 * 1.07x

Let y = balance y = 5000 * 1.0713

Let a = initial deposit y = 5000 * 2.4098

Let b = interest rate y = 12049.23

y = a * bx Jenny has $12,049.23 at age 18.

y = 5000 * 1.07x

3.  The average number of minutes used on a cell phone each month in the year 2007 was 106 minutes. Since then, the number of minutes used each month has decreased by 2% each year. Write an equation to model the number of minutes used each month. Find the average number of minutes used on a cell phone in the year 2013.

Given Answer:

Let x = number of years since 2007 y = 106 * 1.02x

Let y = number of minutes used each month y = 106 * 1.026

Let a = number of minutes used each month in 2007 y = 106 * 1.12616

Let b = the decay factor y = 119.4

y = a * bx In 2013 the average number of

y = 106 * 1.02x minutes used each month was 119.

4.  Todd deposited $7000 in a bank account earning 3% interest compounded yearly in 2008. Write an equation to model the amount of money in the account. Find how much money Todd will have in the account in 2015.

Given Answer:

Let x = number of interest periods y = 7000 * 1.03x

Let y = balance y = 7000 * 1.0315

Let a = initial deposit y = 7000 * 1.55796

Let b = interest rate y = 10905.77

y = a * bx Todd has $10,905.77 in 2015.

y = 7000 * 1.03x

Directions for Inserting an Image into a Word Document:

  1. Scan your document(s) and save it (them) as a .jpg file. Save the images using file names that relate to the assignment.
  1. Open the Word document.
  1. On the first line of the Word document, please type the following:

“Last Name_First Name_Assignment Name”

(Example: Doe_Jane_U1L1_AKA)

  1. Save the file with a file name such as “Last Name_First Name_Assignment Name.”
  2. Place your cursor in the Word file where you want to insert the image.
  3. From the top tab, select the Insert option.

  1. Select Picture.
  1. Locate the file on your desktop. Click on the file and click Insert. The image will then be inserted into your document.

  1. The image will now be inserted into your file. It will look something like this:

Doe_Jane_U1L1_AKA

This is my sample Applied Knowledge Assessment file that will make loading my assignments into EdMastery a lot easier!

*Note: To insert another image, simply place the cursor at the end of the image and press Enter. You are now ready to repeat the process until you have loaded all of your images for the assignment into one Word document!
