Students will be asked to create two scatter plots (one for games 1-23 and a second for games 24-46). Students will then choose appropriate regression models for the growth of advertising costs. Students will choose these models based on visual representations as well as appropriate r or r2 values. Teachers can also introduce residuals here. Teachers can also help the students graph the equations as a piecewise function so that they can see the change in growth rate. Super Teachers need to

The TI84 calculator has many built in functions that are never used. This document is designed to be a quick tutorial on how to use many of the most useful ones. All of the functions can be found by going through the CATALOG (2ND 0). There are other methods for reaching each of these functions, however, this tutorial will not address those directions, absolute value, circle, factorial, conjugate, gcf, gcd, lcm, remainder, divisor,

: According to Wikipedia, the London Eye is the largest Ferris Wheel in the Western Hemisphere. It took 7 years to build the Eye and it was originally known as the Millennium Wheel. The circumference of the Eye is approximately 424m. The total weight of the wheel alone is 2100 tonnes, which makes it 20 times heavier than Big Ben. Over 3.5 million people ride the Eye every year. One complete rotation on the Eye takes about 30 minutes. On a clear day, you can see up to 25 miles in each dire

More than 200 years ago, a wealthy Pennsylvania merchant named Jacob DeHaven lent $450,000 to the Continental Congress to rescue the troops at Valley Forge. That loan was apparently never repaid.The descendants say that they are willing to be flexible about the amount of a settlement and that they might even accept a heartfelt thank you or perhaps a DeHaven statue.
