13. You purchase a computer for $975.00 plus 5% sales tax. You decide to finance it through the store's 0% program for 12 months. The terms state you pay nothing until the 12 months are over.

The $4,000.00 account will earn 4 times the amount of interest.
The $4,000.00 account will earn 2 times the amount of interest.
The $4,000.00 account will earn half the amount of interest.

16. You invest $4,000.00 for seven months at a 4.25% APR. How much interest will you earn? (1 point)

18. Your original purchase price was $950.00 plus 5% sales tax. You enter into an agreement where the interest (12.5% APR) is waived for the first 12 months provided you make the required monthly payments; otherwise the interest is accrued from the date of purchase on the original amount (including sales tax).

Answer 2

Roller Coaster Worksheet
Name:

Use any graphing technology of your choice, and answer the following questions about your observations. Please use complete sentences.

Part 1:

Scenario 1:

Graph y = –2x2 + 6. Describe what you see.







–2x2 + 6 is what kind of polynomial? Classify the polynomial by degree and number of terms.







Next, graph y = (-1/10)x2 + 6. Describe what you see. How is what you observe here different from what you observed in part A?







If you wanted a really steep hill for your roller coaster, would you use the graph of y = –2x2 + 6 or y = (-1/10)x2 + 6? Why? What part of the expression affected the steepness?







Using the same reasoning from part D, create an equation that will be steeper than both equations, and explain your reasoning.







Scenario 2:

Graph y = x3 – 2x2 + 6. Describe what you see.







x3 – 2x2 + 6 is what kind of polynomial? Classify the polynomial by degree and number of terms.







Next, graph y = x3 – 4x2 + 6. Describe what you see. How is what you observe here different from what you observed in part A?







If you wanted the middle part of your roller coaster to have a steeper drop, would you use the graph of y = x3 – 2x2 + 6 or y = x3 – 4x2 + 6? Why? What part of the expression affected the steepness?







Using the same reasoning from part I, create an equation that will be steeper in the middle than both equations, and explain your reasoning.







Part 2: Designing a roller coaster

Look at the polynomial below.

y = ax3 + bx2 + cx + d

Graph this using any graphing technology of your choice. However, replace the variables a, b, c, and d with numbers. For example, you could graph y = 2x3 + 3x2 – x + 2. Observe the graphed outcomes. This is an investigation process to see what types of curves and lines you can produce with this equation.

Special Note: You may make any coefficient zero. This eliminates the variable. For example, if you wanted to make y = 3x2 + 2, a and c would be zero to cancel out the x3 and the x terms.

Select GeoGebra if you would like to use a graphing interactive to complete this part of the project.

Graph different functions by changing a, b, c, and d to “design” your ideal roller coaster. Come up with at least four equations that, when pieced together, would make your ultimate roller coaster. Be sure to note what window sizes you’re using in your graphs. You may have to change the default size to better see each of the polynomials’ shapes.
Use a drawing program (or draw by hand and scan) to recreate your roller coaster, and for each section, provide the equations you decided upon.

You may view a sample roller coaster to get an idea of what is expected.
Part 3: Conclusion

If working individually, you can do a reflection and a theme summary.

Reflection: Write a paragraph, of 3 or more sentences, as you reflect on this activity and your final product. You may use specific questions to guide your thoughts, if needed.

Theme Summary: Using complete sentences, describe the theme of your roller coaster (example: monsters), and give your instructor details as to what your roller coaster would look like, feel like, and what makes your roller coaster unique. You can present this information however you like.

You will submit the following to your instructor as assignment 08.08 Exploring Graphs of Polynomials.

Your answers to part 1. (10 points)

Your roller coaster from part 2 with at least four pieces and four equations (one equation for each piece). (8 points)

Your roller coaster description: theme from part 3. (5 points)

Your reflection from part 3. (2 points)
