Model Exponential Growth and Decay (4.7.38-39) A biologist recorded a count of 300 bacteria present in a culture after 5 minutes and 1050 bacteria present after 28 minutes. a. To the nearest whole number, what was the initial population in the culture? The initial population was around 219 bacteria b. Rounding to four decimal places, write an exponential equation representing this situation. B(t) 10e 30t c. To the nearest minute, how long did it take the population to double? The...

LOGISTI We know that if the number of individuals, N, in a population at time t follows an exponential law of growth, then N-N, exr where k >0 and No is the population when t -o. es that at time, t, the rate of growth, N, of the population is proportional to dt dN the number of individuals in the population. That is, kN Under exponential growth, a population would get infinitely large as time goes on. In reality, when...

Modeling Exponential Growth and Decay A biologist recorded a count of 360 bacteria present in a culture after 7 minutes and 1200 bacteria present after 20 minutes. a. To the nearest whole number, what was the initial population in the culture? The initial population was around bacteria. b. Rounding to four decimal places, write an exponential equation representing this situation. B(t) = c. To the nearest minute, how long did it take the population to double? The doubling time of...
