Hello dear tutors, NEEDED ASAP following questions are the rate of change . Solve on paper please because it makes it harder for me to understand when types up on computer. I will give good feedback.Thank You

2. The area, A, in square meters, of a circular oil spill after t min is given by A = nt . The instantaneous rate of change of the area of the oil spill after 2 min is approximately a. 3.14 m2/min b. 6.28 m2/min c. 12.57 m2/min 10 d. 18.85 m2/min 3. A secant drawn through the points shown on the graph has a slope of -6 4 a. c. 5 2 b. d. 10 3 0 2 X 3. The population of a town is modeled by P(t) = 25t2 + 150t + 5000, where P(t) is the size of the population and t is the number of years since 2000. a) Calculate the average rate of change in the population between 2008 and 2016. [2] b) Does the average rate of change in population increase, decrease, or stay the same? Explain how you made your decision. [1]5. Given the following graph, determine the instantaneous rate of change of the water depth at 15min. [3] water depth (metres) 6 5 P 5 10 15 20 25 30 35 40 time (minutes)
