Population In Exercises 51-54, the population (in millions) of a country in 2015 and the expected continuous annual rate of change k of the population are given. ( Source: U.S. Census Bureau, International Data Base)
(a)Find the exponential growth model
for the population by letting
(b)Use the model to predict the population of the country in 2030.
(c)Discuss the relationship between the sign of k and the change in population for the country.

- What situations are best modeled by a logistic equation? Give an example, and state a case for why the example is a good fit.arrow_forwardTable 2 shows a recent graduate’s credit card balance each month after graduation. a. Use exponential regression to fit a model to these data. b. If spending continues at this rate, what will the graduate’s credit card debt be one year after graduating?arrow_forwardWhat does the y -intercept on the graph of a logistic equation correspond to for a population modeled by that equation?arrow_forward
- What might a scatterplot of data points look like if it were best described by a logarithmic model?arrow_forwardSales of a video game released in the year 2000 took off at first, but then steadily slowed as time moved on. Table 4 shows the number of games sold, in thousands, from the years 20002010. a. Let x represent time in years starting with x=1 for the year 2000. Let y represent the number of games sold in thousands. Use logarithmic regression to fit a model to these data. b. If games continue to sell at this rate, how many games will sell in 2015? Round to the nearest thousand.arrow_forwardTable 6 shows the year and the number ofpeople unemployed in a particular city for several years. Determine whether the trend appears linear. If so, and assuming the trend continues, in what year will the number of unemployed reach 5 people?arrow_forward
