A major scientific periodical published an article in 1990 dealing with the problem of global warming. The article was accompanied by a graph that illustrated two possible scenarios. (a) The data might be modeled by an exponential function of the form f(x) = (4.044 x 10-38) (1.0444%). (b) The warming might be modeled by a linear function of the form g(x) = 0.009x - 17.67 In both cases, x represents the year, and the function value represents the increase in...
Because the Florida manatee population is threatened, the Florida Maatee Sanctuary Act of 1978 was enacted to protect the species. Scientists interested in the relationship between the number of manatee deaths and time collected the data shown in the table.

To fit data to an exponential model like y = AeKt, we first use a logarithm to linearize it: . n y n A k t Since A is a constant, so is ln A, and we can write this generically as ln y = co + cit. The table below shows the years different planes were first produced, along with how many displays (gauges, screens, etc.) were present in the cockpit. Year Introduced, y (Year after 1900)...
