The equation is y 3e2x y 3 e 2 x. N t N 0 e t t displaystyle N tN_ 0e -ttau and that. 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.
The amount at time 0 r.
The exponential decay is found in processes where amount of something decreases at a rate proportional to its current value. Heres an exponential decay function. A quantity is subject to exponential decay if it decreases at a rate proportional to its current value. AtA0 e -rt where At and A0 are amounts of some quantity at time t and 0 respectively r is the decay rate and t is the time passed.
