In Algebra 2, the exponentialewill be used in situations ofcontinuous growth or decay.The following formula is used to illustratecontinuous growth and decay.If a quantity grows continuously by a fixed percent, the pattern can be depicted by this function. Continuous Exponential Growth or Decay A=...
Exponential growth and decay often involve very large or very small numbers. To describe these numbers, we often use orders of magnitude. The order of magnitude is the power of ten when the number is expressed in scientific notation with one digit to the left of the decimal. For example, ...
Growth and Decay But sometimes thingscangrow (or the opposite: decay) exponentially,at least for a while. So we have a generally useful formula: y(t) = a × ekt Wherey(t)= value at time "t" a= value at the start k= rate of growth (when >0) or decay (when <0) ...
growth model, and is denoted by T 10 . For a growth equation y = y 0 e kt , we have T 10 = ln10 k . 7 Model #2: Radioactive Decay It is known that radioactive elements decay at a rate proportional to the amount of the element present: in other words, the relative rate of...

Exponential Growth and Decay Suppose y=ekx. Then dy/dx=kekx. Since y=ekx, dy/dx=ky. This is an example of a differential equation. If y=2ekx, then dy/dx=2kekx, which is once again equal to ky. More generally, if y=Aekx, then dy/dx=Akekx, which is once again equal to ky...
