High concentrations of carbon monoxide CO can cause coma and possible death. The time required for a person to reach a COHD level capable of causing a coma can be approximated by the quadratic model T= .0002x² - .316x + 127.9, where Tis the exposure time in hours necessary to reach this level and 500 sxs 800 is the amount of carbon monoxide present in the air in parts per million (ppm). a) What is the exposure time when x = 520? b) Estimate the concentration of CO necessary to produce a coma in 4 hr. What is the exposure time when x= 520? hr
