Current Attempt in Progress The concentration of the car exhaust fume nitrous oxide, NO2, in the air near a busy road is a function of distance from the road. The concentration decays exponentially at a continuous rate of 2.54% per meter.' At what distance from the road is the concentration of NO2 half what it is on the road? Round your answer to the nearest integer. At i meters from the road the concentration of NO2 in the air is half the concentration on the road. At what distance from the road is the concentration of NO2 40% of what it is on the road? At i meters from the road the concentration of NO, in the air is 40% of the concentration on the road.

The concentration of the car exhaust fume nitrous oxide, NO2, in the air near a busy road is a function of distance from the road. The
concentration decays exponentially at a continuous rate of 2.54% per meter.'At what distance from the road is the concentration of
NO2 half what it is on the road?
Round your answer to the nearest integer.
At i
meters from the road the concentration of NO, in the air is half the concentration on the road.
At what distance from the road is the concentration of NO, 40% of what it is on the road?
At i
meters from the road the concentration of NO2 in the air is 40% of the concentration on the road.
