The population P (in millions) of Italy from 2003 through 2015 can be approximated by the model P = 57.59e0.0051t, where t represents the year, with t = 3 corresponding to 2003. (a) According to the model, is the population of Italy increasing or decreasing? Explain. Because the coefficient of the model is -Select- v the population is -Select- ' (b) Find the populations of the country in 2003 and 2015. (Round your answers to three decimal places.) 2003 2015 million million (c) Use the model to predict the populations of the country in 2025 and 2034. (Round your answers to three decimal places.) 2025 2034 million million
