In this case, it says the rate that the mass decreases is proportional to the mass. The rate is the derivative which must be equal to -kM where k is just a constant. Note that it is -kM since the mass is decreasing. WebSep 20, 2015 · The concept of inverse proportionality is often approached at the beginner level by hand-waving in this fashion; in this equation as x increases, y decreases.
