If I were to draw a line from my position at, say, time = 10 to time = 20, then the slope of this line would be my average walking speed between times 10 and 20. Finally, I would like to be able to mathematically describe my speed at different times during the walk. 8 Graph of my walk showing average speed. 9 Graph of my walk showing several instantaneous speeds. points). 9. Mathematically, this is a topic in differential calculus, which we certainly aren’t going to get into. Fortunately, what I’m describing is very easy to picture intuitively.
Can you estimate the instantaneous speeds near the beginning of the walk and near the end of the walk? Chapter 2 Compound Interest The most common, if not universal, way to express the amount of interest to be paid on a loan is the annual percentage rate (APR).

9 would be my incremental tax rate. Don’t worry if these terms seem strange to you; I’ll start from the beginning and go through them all in Chapter 9. 10 INEQUALITIES AND RANGES OF NUMBERS The symbol < means “is less than,” as in 3 < 4. If x represents the numbers of the months of the year, for example, x < 4 means x could be 1, 2, or 3. The symbol ≤ means “is less than or equal to,” so that x ≤ 4 in the above example means x could be 1, 2, 3, or 4. Similarly, the symbols > and ≥ mean “is greater than” and “is greater than or equal to,” respectively.
