WebSep 17, 2015 · A logarithmic model is a model that measures the magnitude of the thing it's measuring. It can also be seen as the inverse of an exponential model. For example, exponential growth is very common in nature for things like radioactivity, bacterial growth, etc., being written as N(t) = N_0e^(kt) or N(t) = N_0a^t So if wanted to know how much … WebWrap-around tailpiece.
