Over 4 years, researchers studied the growth of a fish population and found its growth rate to P'(t) = 10 - 3 + t3, where t e [0, 4] is in years. 1+ t2 - hand | P'(t)dt (to the closest integer) and interpret the result. Be specific.

Table 6 shows the population, in thousands, of harbor seals in the Wadden Sea over the years 1997 to 2012. a. Let x represent time in years starting with x=0 for the year 1997. Let y represent the number of seals in thousands. Use logistic regression to fit a model to these data. b. Use the model to predict the seal population for the year 2020. c. To the nearest whole number, what is the limiting value of this model?

What is the y -intercept on the graph of the logistic model given in the previous exercise?

Table 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?
