WebResearchers recorded that a certain bacteria population grew from 100 to 300 in 3 hours. At this rate of growth, how many bacteria will there be 24 hours from the start of the … WebJul 7, 2024 · THe number of bacteria is = 5243 bacteria Explanation: The growth of bacteria is according to the differential equation dN dt = kN Integration of this equation yields ln( N 2 N 1) = k(t2 −t1) or ( N 2 N 1) = ek(t2−t1) The initial conditions are N 1 = 500 at t1 = 0 Also, N 2 = 800 at t2 = 1h Therefore, ln(800 500) = k(1 − 0) Therefore, k = ln(8 5)
