Because 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 lead concentrations in parts per million of samples taken from different distances from roads.t Lead Concentration in Soil Near Roads Distance, x (meters) Lead, L (ppm) 90 10 60 15 40 20 32 (a) Find a log model for these data. (Round all numerical values to three decimal places.) 5 SxS 20 L(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 nearest integer.) 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.) 5
