Math 124 Name _______________#13 PRACTICAL INTERPRETATION & ESTIMATION 2.41. Estimate (1940)P and give a practical interpretation. P represents the amount of carbon dioxide (ppm) in the atmosphere, t represents the year.2. The speed of a car in mph can be expressed in terms of the length of a skid mark in feet when brakes are applied. Estimate (20)S and give a practical interpretation if ( ) 2 5S L L.3. Suppose a filter has been designed to remove 100 grams of sediment from a storage tank. Let ( )Q t be the amount of sediment in the tank at time t. A. Estimate (3)Q if the filter removes a fixed amount of sediment each hour, say 2.3 grams. B. Estimate (3)Q if the filter removes a fixed percentage of sediment each hour, say 20 %. C.
