Population growth or decline follows an exponential curve. 2. Growth rates are constant (for deterministic growth). 3. Mean growth rates are constant (for stochastic growth with environmental fluctuations). Webloan with interest, and four on population dynamics. In the latter Euler assumed that the population P n in year n satisfies P n+1 =(1+x)P n for all integer n. The growth rate x is a positive real number. Starting from an initial condition P 0, the population in year n is given by P n =(1+x)n P 0. This is called geometric or exponential growth ...

If a quantity starts at size P 0 and grows by R % (written as a decimal, r) every time period, then the quantity after n time periods can be determined using either of these relations: Recursive form: P n = ( 1 + r) P n − 1. Explicit form: P n = ( 1 + r) n P 0 or equivalently, P n = P 0 ( 1 + r) n. michelle swainsonWebFor example, a growth of 2x per hour is geometric growth; every hour, a population doubles, with that rate never changing. So if that population starts with 2, the next hour is 4, then 8, then 16. Exponential growth would be more like 2x^y of growth. Uhh, there are no questions I see.
