In the year 2000, the population of Toledo, Ohio was approximately 520,000. Assume the population is increasing at a rate of 4.7 % per year. a. Write the exponential function that relates the total population, P(t), as a function of t, the number of years since 2000. P(t) = b. Use part a. to determine the rate at which the population is increasing in t years. Use exact expressions. P'(t) = people per year c. Use part b. to determine the rate at which the population is increasing in the year 2011. Round to the nearest person per year. P'(11) = people per year Let f(z) = 3In(x). Enter answers as reduced fractions. Then f' (x) is and f' (7) is f'' (x) is and f''(7) is Let f(x) = 4x Inc f' (z) = Rounding to 3 decimal places, f' (e 4 ) = If f(x) = 4 cos(2 In(z)), find f'(z). Find f'(5) rounded to 3 decimal places. Question later Let f(z) = In 23(2 + 5)(202 + 7) 2 ] f' (x) = You need not put it over a common denominator
