Chapter 6.2, Problem 31E
Women in the Workforce The following table gives the number of women age 16 years and older (in millions) in the U.S. civilian workforce for selected years from 1950 and projected to 2050.
- a. Use x as the number of years past 1950 to create a cubic model using these data.
- b. During what year does the model indicate that the number of women in the workforce will reach its maximum?

A new coronavirus recently triggered a global pandemic. It spreads from 5 cases in March to tens of thousands by May in the Philippines. Case contamination is comparable to what we call exponential spread.
Create a table of values representing the covid19 confirmed cases in the Philippines during the first 15 days of March 2020. You can conduct your research online and then plot the results on a Cartesian plane. You can use paper and pencil or any graphing app that is appropriate.
Questions to ponder:
In order to slow down the growth, what can you do to the curve? In real-life, what must be done to flatten the curve? _________________
An aerobic exercise instructor submitted to the shipping company the
data given in the following table, which shows the recommended
maximum exercise heart rates for individuals of the given ages. See
table below. If the Chief engineer is 40 years old, predict his maximum
exercise heart rate. If your answer has decimal point round it off to two
decimal places. Do not put space, comma or unit in your answer.
