Two bacteria cultures are compared to one another for a period of time. The first culture is left untreated. The number of bacteria in this culture after t hours is given by the function B₁ (t)=8530(0.93) The second culture is treated with a probiotic. The number of bacteria in this culture after thours is given by the function B₂(t)=6860(1.12) A B с D The untreated culture is demonstrating exponential growth, while the treated culture is demonstrating exponential decay. The untreated culture is demonstrating exponential decay, while the treated culture is demonstrating exponential growth. Both cultures are demonstrating exponential decay. Both cultures are demonstrating exponential growth

You want to estimate how many fish there are in a small pond.  Let's suppose that you first capture n1=500 fish, tag them, and throw them back into the pond.  After a couple of days you go back to the pond and capture n2=120 fish, of which k=30 are tagged.  Estimate the number of fish in the pond. There are approximately Answer fish in the pond.

The equation n = 0.03t² 0.58t + 3.98, models, n, the number (in millions) of people who moved to another state in the year that is t years since 1990. The table below shows some of the data that were used to find this model. Year 1995 1998 2001 2004 2006 Number of People Who Moved to Another State (millions) a. When t = 1.8 1.2 1.1 1.5 2.1 0 what is the value of n? What does it mean in this situation? Select an answer b. Estimate the number of people who moved to another state in 2005. million (Round to the nearest tenth of a million.) c. Predict the number of people who moved to another state in 2014. million (Round to the nearest tenth of a million.)
