A population of insects currently numbers 22,100 and is increasing at a rate of R(t) = 1215e0.14t insects/week. If the survival function for the insects is S(t) = e−0.2t, where t is measured in weeks, how many insects are there after 12 weeks?(Round your answer to the nearest whole number.)

In a town whose population is 2600, a disease creates an epidemic. The number of people N infected t days after the disease has begun is given by the function N(t)- 2600 1+34 -0.6t. Complete parts a) through c) below a) How many are initially infected with the disease (t = 0)? (Round to the nearest whole number as needed.) b) Find the number infected after 2 days, 5 days, 8 days, 12 days, and 16 days. The number infected...
A small lake is stocked with a certain species of fish. The fish population is modeled by the function P = 12 1 + 4e−0.4t where P is the number of fish in thousands and t is measured in years since the lake was stocked. (a) Find the fish population after 4 years. (Round your answer to the nearest whole fish.) fish (b) After how many years will the fish population reach 6000 fish? (Round your answer to two decimal...
This exercise uses the population growth model. The count in a culture of bacteria was 400 after 2 hours and 25,600 after 6 hours. (a) What is the relative rate of growth of the bacteria population? Express your answer as a percentage. (Round your answer to the nearest whole number.) 104 % (b) What was the initial size of the culture? (Round your answer to the nearest whole number.) 200 x bacteria (c) Find a function that models the number...
A small take is stocked with a certain species of fish. The fish population is modeled by the function P- 14 1+ 4e -0.80 where P is the number of fish in thousands and t is measured in years since the lake was stocked. (6) Find the fish population after 3 years. (Round your answer to the nearest whole fish) fish (1) After how many years will the fish population reach 7000 fish?

Based on mark/recapture studies between 2001 and 2006, the Southern Beaufort Sea 2006 population of polar bears is approximately 1526 bears. Suppose that since 2006 the population is being renewed at a rate of r(t) = 0.180 + 0.012t thousand bears per year and that the survival rate is 89%, where t = 0 corresponds to 2006.† (a) How many of the 2006 population of 1526 polar bears will still be alive 27 years from then? (Round your answer to...
