Sustainability Problem CO_2 is the most important gas for controlling the earth's temperature. Greenhouse gases are essential for warming the earth; they absorb a wide range of energy and then re-emit it, where part of the energy returns to Earth and warms the surface. The greenhouse effect can be contributed to carbon dioxide (20%), water vapor (50%), and clouds (25%), The amount of water vapor in the air is dependent on Earth's temperature; warmer temperature allows for increased evaporation and so increased water vapor. Scientists have found that when carbon dioxide concentrations increase (there is mote CO_2 in the air), air temperatures increase (carbon dioxide "sets the temperature", so to speak), and so water vapor concentration increases, amplifying greenhouse heating. If one gallon of motor gasoline (without ethanol) is burned, then about 19.64 pounds of CO_2 is produced. () The function M(s) = -.041s^2 + 6.7s - 44/.7s represents miles traveled per pound of CO_2 released as a function of speed (in MPH) for a Hyundai Sonata. The domain of this function is [10, 90]. Find the value of M(30) and interpret in a complete sentence using; units. Find the value of M(60) and interpret in a complete sentence using units. Calculate M'(s) and set it equal to 0 to find the stationary points to 2 decimal places (you may use your calculator). Which speed maximizes miles traveled per pound of CO_2? What is the maximum miles traveled per pound of CO_2?
