If C=0.003x^(3)+0.02x^(2)+6x+250 gives the amount of carbon pollution in air in an area on the entry of x number of vehicles,then find the marginal carbon pollution in the air, when 3 vehicles have entered in the area and write which value does the question indicate.

The amount of pollution content added in air in a city due to x- diesel vehicles is given by P(x)=0.005x^(3)+0.02x^(2)+30x. Find the arginal increase in pollution content when 3 diesel vehicles are added and write which value is indicated in the above question.

[A] : PAN is a secondary pollutant . [R] : The secondary pollutants are produced by the combination of primary emitted pollutants in the atmosphere .
