WebJul 17, 2024 · Figure 4.1. 1: Graph of Linear Population Growth. The population growth can be modeled with a linear equation. The initial population P0 is 48,080. The future population depends on the number of years, t, after the initial year. The model is P (t) = 46,080 + 1000 t. To predict the population in 2013, we identify how many years it has been from ... Webk = relative decay rate that is constant. Note that k > 0. t = the time the population decays. P(t) = the population that is left after time t. Notes 1. Many times the rate of decay is expressed in terms of half-life, the time it takes for half of any given quantity to decay so that only half of its original amount remains. 2.
