2. At time t = 0 a bacteria culture has No bacteria. One Hour later the...
11. The population of a culture of bacteria at time t (in hours) is given by the following equation: P(t) 10e Find the doubling time.
3. The population of bacteria in a culture decreases at a rate proportional to the number of bacteria present at any time t. The initial population is 500 and the population decreases 10% in 1 hour. Determine the half-life of the population of bacteria. How long does it take for the population to be 10? (8 marks ).
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?
The population of bacteria in a culture can be modeled by P left parenthesis t right parenthesis equals negative 0.01 t cubed plus 12.96 t plus 10, where t is the time in hours after the culture was started and P left parenthesis t right parenthesis is the population in thousands. Complete the table to determine the population of the bacteria for the given values of time, t. This is a "Fill in the blank" question so please give ONLY...
3 ✓ Question 4 (5 points) Solve the problem. A culture of bacteria obeys the law of uninhibited growth. If 140,000 bacteria are present initially and there are 609,000 after 6 hours, how long will it take for the population to reach one million? 6 9 A/ 10
This exercise uses the population growth model. A culture starts with 8100 bacteria. After 1 hour the count is 10,000. (a) Find a function that models the number of bacteria n(t) after t hours. (Round your r value to three decimal places.) n(t) = (b) Find the number of bacteria after 2 hours. (Round your answer to the nearest hundred.) bacteria (C) After how many hours will the number of bacteria double? (Round your answer to one decimal place.) hr
A biologist recorded a count of 340 bacteria present in a culture after 9 minutes and 950 bacteria present after 22 minutes. A. To the nearest whole number, what was the initial population in the culture? B. Round to four decimal places, write an exponential equation representing this situation. C. To the nearest minute, how long did it take the population to double?
This exercise uses the population growth model. A culture starts with 8700 bacteria. After 1 hour the count is 10,000. (a) Find a function that models the number of bacteria n(t) after thours. (b) Find the number of bacteria after 2 hours. (c) After how many hours will the number of bacteria double?
The number of bacteria in a culture is given by the function n(t) = 960e. where t is measured in hours. (a) What is the exponential rate of growth of this bacterium population? Your answer is (b) What is the initial population of the culture (at t=0)? Your answer is (c) How many bacteria will the culture contain at time t-4? Your answer is
A culture of bacteria begins with 92 individuals and triples every 26 minutes. If t is measured in minutes and P (t) is the population of bacteria every hour, which of the following expressions best models popuLation growth. select one: a) P(t)=92(3)t/26 b) P(t)= (3)26t+92 c) p(t)= 92(3)26/60(t) d) P(t)= 92(3) 60/26(t)
