1. Suppose a magic genie gives you a choice. Option 1: He will give you $1000 each day in the month of March. Option 2: He will give you 1¢ the first day and then double the amount you have each day for the month.
a. Without thinking about it too much, which option would you pick?
b. Create a table in a blank Excel file to show that amount you have each day of the month with each option. Fill in appropriate formulas for each column and extend the table for all 31 days. Copy and paste the table here.
2. Beryllium-11 is a radioactive isotope of the alkaline metal Beryllium. Beryllium-11 decays at a rate of 4.9% every second.
a. If there were 100 grams initially of beryllium-11, how many grams would be remaining after 10 seconds? Either copy and paste the table or show the equation used to answer the question.
b. What is the half life of beryllium-11? In other words, how long would it take for half of the original 100 grams to decay? (you will need to make a table for this)
3. In 1998, the population of Nigeria was 106 million people and was growing at 3% annually and the population of Russia was 147 million and was decreasing 0.1% annually.
a. Make a table in Excel showing the populations of both countries for 20 years starting in 1998.
