Question 891560: please help me with this math problem its really important to pass my class

Years (1982) (1983) (1984) (1985) (1986) (1987) (1988) (1989) (1990) (1991) (1992) (1993) (1994) (1995) (1996)
Cumulative AIDS Cases in the U.S. (1,617) (4,758)(11,069) (23034)( 42327) (71273) (107144) (150168) (198938) (258538) (336522) (414163) (483122) (544736) (581429)

1. Plot the data from the table on graph paper. The independent variable, plotted on the x-axis, represents the year, and the dependent variable, plotted on the y-axis, represents the number of new AIDS cases. The plotted data on graph paper serves as a visual companion to the above table.

2. Plot the data from the table using the graphing calculator. Use the same axes for the dependent and independent variables as in the previous step.
3. On the graphing calculator, determine the exponential curve that best fits the data from 1982 to 1996. When entering the data, let the years 1982 through 1996 be represented by the numbers 2 through 16.
4. Use the graphing calculator to graph this equation on your plotted data. Discuss the fit.

Question 891865: Two students are discussing moving between degrees and radians. Critique and use their arguments in the questions that follow their discussion. Use complete sentences and proper grammar to receive full credit.
James
I remember that 360� = 2Pi radians In finding the radian measure of 120� I divided 120 by 360 to get 1/3. Since my angle was 1/3 of the whole circle and that there are 2Pi radians in a circle I think that the angle will be 1/3 of 2Pi which is 2Pi/3
Jim
If 360 degrees equals 2Pi radians then if I divide both sides 360, then 1 degree is equal to Pi/180. There 120 degrees times Pi/180 would be radian measure, which reduces to 2Pi/3.
a. Using James� method, find the radian measure of 30 degrees.
b. Using Jim�s method, find the radian measure of 30 degrees.
c. Which method is your preferred method? Why?
