Exercise 4.4.4 Imagine that you have 500 formulas to learn (I know, yikes). If you can learn 15 formulas after 5 hours, the function L(t) = 500(1 - e-0.0061t) approximates the number of formulas that you will learn after { hours. Use this formula to answer the following. 1. How many formulas will you learn after 30 hours? 2. How many formulas will you learn after 60 hours? 3. On the next page is the graph of the function L(t). What aspects of the graph make sense given the context of the problem? What aspects of the graph don't make sense
