In this lesson, learn about exponential decay and find real-life exponential decay examples. Learn how to use the model to solve exponential decay...
To find the half-life of a function describing exponential decay, solve the following equation:12A0=Aoekt12A0=AoektWe find that the half-life depends only on the constant k and not on the starting quantity A0A0.The formula is derived as follows...
We now turn toexponential decay. One of the common terms associated with exponential decay, as stated above, ishalf-life, the length of time it takes an exponentially decaying quantity to decrease to half its original amount. Every radioactive isotope has a half-life, and the process describing...
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=...

tis in meters (distance, not time, but the formula still works) y(1000)is a 12% reduction on 1013 hPa =891.44hPa So: 891.44 = 1013 ek×1000 Now some algebra to solve fork: Divide both sides by 1013:0.88 = e1000k Take the natural logarithm of both sides:ln(0.88) = ln(e1000k) ...

Elements of an Exponential Decay Formula To start, it's important to recognize the exponential decay formula and be able to identify each of its elements: y = a (1-b)x In order to properly understand the utility of the decay formula, it is important to understand how each of the factors...
Algebra 2 Goals: 1.Write and graph exponential functions of the form (3.15)2.Use exponential equations to solve problems. Solve by graphing, substitution. (3.17)3.Use exponential equations of the form where r is given as a rate of growth or decay to solve problems. (4.03)4....
We don’t just use the natural exponential function because it makes algebra become easy, though. It’s also an accurate model of many processes in our world, including the growth and decay of biological systems and what happens to the money when it is compounded. Nth Root Function Nth root...
