Problems
If you start a biology experiment with 5,000,000 cells and 45% of the cells are dying every minute, how long will it take to have less than 1000 cells? Start by constructing a model of the form A=A(knot)e^kt, then use it to answer the question.
If you put aside 1 cent on the first day, 2 cents on the second day, 4 cents on the third day, and so forth (doubling the amount each day) the model A(t)=2^t-1 can be used to determine the total of money put aside after t days. How many days will it take before you become a millionaire?
I am unsure how to set these up to solve them. Can you please help me.
thanks
