A Initial growth the amount before measuring growth or decay r Growth or Decay rate most often represented as a percentage and expressed as a decimal x Number of time intervals that have passed. Y a 1 b x. X number of time intervals passed days months years y amount after x time.
The number e also known as Eulers number is a mathematical constant approximately equal to 271828 and can be characterized in many ways.
It occurs when the instantaneous rate of change that is the derivative of a quantity with respect to time is proportional to the quantity itself. Xt 10000 1 005 t 10000 105 t. B 1 - r Decay Factor. How do I calculate growth rate.
