CalculusQ&A LibraryBecause of past use of leaded gasoline, the concentration of lead in soil can be associated with how close the soil is to a heavily traveled road. The table shows average leadconcentrations in parts per million of samples taken from different distances from roads.tLead Concentration inSoil Near RoadsDistance, x(meters)Lead, L(ppm)90106015402032(a) Find a log model for these data. (Round all numerical values to three decimal places.)5 SxS 20L(x) =ppm is the concentration of lead in the soil x meters from a heavily traveled road(b) An apartment complex has a dirt play area located 8 meters from a road. Calculate the lead concentration in the soil of the play area. (Round your answer to the nearestinteger.)L(8) =ppm(c) Find an exponential model for the data. Compare this model to the log model found in part (a). (Round all numerical values to three decimal places.)5Question
