I'm pretty familiar with the calculator settings but I don't know how to answer these questions. It would be appreciated if you would show me the steps in how you answer these questions.
1. The per-share dividends for Wachovia Corporation increased from $1.38 in
1995 to $2.06 in 1999. Assume that the rate of change was constant.
(a) Using data points of the form (x, dividend), where x is the number of
years since 1995, determine whether a linear function describing this
information would be a direct variation. Why or Why not?
(b) If the function describing this information is in the slope-intercept form,
what is m and what is its interpretation?
2. Gateway manufactures and sells computers. This company's scale rose from $5.0 billion in 1996 to 10.4 billion in 2000. Assuming a constant rate of
increase, find the average rate of change in sales during this period.
I entered 0 (representing 1996) & 4 (representing 2000) in my L1 column corresponding to 5.0 and 10.4 under L2 in my calculator . I got 1.35 as the average rate of change in sales. Is that correct?
