answer the question to part b 1 2 and 3

Questions 1 through 3 refer to the following. A wind turbine uses the power of wind to generate electricity. The blades of the turbine make a noise that can be heard at a distance from the turbine. At a distance of d = 0 meters from the turbine, the noise level is 105 decibels. At a distance of d = 100 meters from the turbine, the noise level is 49 decibels. The noise level can be modeled by the function S given by S(d) = ab?, where S(d) is the noise level, in decibels, at a distance of d meters from the turbine. o Mark for Review H PartB (i) Use the given data to find the average rate of change of the noise level, in decibels per meter, fromd = 0to d = 100 meters. Express your answer as a decimal approximation. Show the computations that lead to your answer. (ii) Interpret the meaning of your answer from (i) in the context of the problem. (iii) Use the average rate of change found in (i) to estimate the noise level, in decibels, at a distance of d = 120 meters. Show the work that leads to your answer.
