There is a strong scientific consensus that human activities arc changing the Earth's climate. Scientists now believe that there is a strikingcorrelation between atmospheric carbon dioxide concentration and global temperature As both of these variables increase at significantrates, there are warnings of a planetary emergency that threatens to condemn corning generations to a catastrophically diminished future. The bar graphs give the average atmospheric concentration of carbon dioxide and the average global temperature for eight selected years. Use this information to solve Exercises 51-52.

51. a. Estimate the yearly increase in the average atmosphericconcentration of carbon dioxide. Express the answer inparts per million. 1.4 ppm per yr
b. Write a mathematical model that estimates the averageatmospheric concentration of carbon dioxide. C. in partsper million, x years after 1950.
c. If the trend shown by the data continues, use yourmathematical model from part (b) to project theaverage atmospheric concentration of carbon dioxide in2050. 450 ppm

- A certain toll road averages 144,000 cars per day when charging $1 per car. A survey concluded that increasing the toll will result in 900 fewer cars for each cent of toll increase. What toll should be charged in order to maximize the revenue?arrow_forwardSuppose that poaching reduces the population of an endangered animal by 4% per year. Further suppose that when the population of this animal falls below 70, it's extinction is inevitable. If the current population of the animal is 1500, when will it face extinction?arrow_forwardAn fruit grower knows from previous experience and careful data analysis that if the fruit on a specific kind of tree is harvested at this time of year, each tree will yield, on average, 127 pounds, and will sell for $4.6 per pound. However, for each additional week the harvest is delayed (up to a point), the yield per tree will increase by 2.1 pounds, while the price per pound will decrease by $0.07. A) How many weeks should the grower wait before harvesting the apples in order to maximize the sales revenue per tree? (Round your answer to the nearest tenth of a week.) Answer: __________ (rounded to the nearest tenth) B) Use your answer in part A to find the actual maximum revenue that can be expected. (Round your answer to the nearest dollar.) Answer: ____________ dollars (rounded to the nearest dollar)arrow_forward

- In a pest-eradication program, sterilized male flies are released into the general population each day. Ninety percent of those flies will survive a given day. How many flies should be released each day if the long-range goal of the program is to keep 20,000 sterilized flies in the population?arrow_forwardSection 30 number 19.
