How long will it take for the population of the bacteria to reach 800?
Round your answer to the nearest tenth of an hour.
500 (2^(t/12)) = 800 , where t is in hours
2^(t/12) = 1.6
take logs of both sides, and use the rules of logs
t/12 log2 = log 1.6
t/12 = log 1.6/log 2
t = 12(log 1.6/log 2)
= appr 8.1 hours
The population of a colony of bacteria is modeled by the function p(x)=50(e^-x - e^-x^2)+10 , for 0 ≤ x, where population P is in thousands, x is in hours, and x = 0 corresponds to the moment of introduction of a certain chemical into the colony's
The population of a bacteria culture increases at the rate of 3 times the square root of the present population. A. Model the population P = P(t) of the bacteria population with a differential equation. B. Solve the differential equation that models the
A biologist grows a culture of bacteria as part of an experiment. At the start of the experiment, there are 75 bacteria in the culture. The biologist observes that the population of bacteria dobules evert 18 minutes. Which of the following equations best
How do I solve this if there is no equation to this 1. The population of the bacteria in a Petri dish increases by a factor of 10 every 10 hour. If there are initally 20 bacteria in the dish, how long will it take before the population increases to 60,000
The population of a colony of bacteria is modeled by the function p(x)=50(e^-x - e^-x^2)+10 ,for 0 ≤ x, where population P is in thousands, x is in hours, and x = 0 corresponds to the moment of introduction of a certain chemical into the colony's
A culture of bacteria in a petri dish is doubling every hour. If there are 100 bacteria at time t=0, how many bacteria will there be in 12 hours?
At the start of an experiment, there are 100 bacteria. If the bacteria follow an exponential growth pattern with a growth rate of 12%, what will be the population after 10 hours (round to the nearest bacteria)? Spell check
Suppose a population of 160 crickets doubles in size every month. The function F(X)= 160 * 2^X gives the population after x months. How many crickets will there be after 2 years? A.)2,684,354,560 crickets B.)640 crickets C.)7,680 crickets D.)655,360
4. The population of a small town is modelled by the function p(t)= 20(4t+3)/2t+5 , where P(t) is the population, in thousands, and t is time, in years, since the start of 1990. a) Is the population currently increasing or decreasing? Justify your answer.
A biologist is researching a newly discovered species of bacteria. At time t=0 hours, she puts on hundred bacteria into a Petri dish. Six hours later, she measures 450 bacteria. Assuming exponential growth, what is the growth rate "k" for the bacteria?
