Air quality. An industrial plant is located on the lakefront of a city. Let (0, 0) be the coordinates of the plant. The city’s residents live in the region R bounded by y = 0 and y = 10 − 0.1x2. (Each unit on the x and y axes represents 1 mile.) Suppose that the concentration of fine particulate matter (in micrograms per cubic meter) at a point d miles from the plant is given by
Find the average concentration of fine particulate matter (to one decimal place) over the region R.
