ccording to a recent data analysis, the amount A(t) of atmospheric pollutants in a certain city is found to pproximately quadruple every 9.5 years. The current amount of pollution in this city is 25 pu (pollutant units), and it is onsidered to be dangerous to stay in the city when the amount of pollutants reaches 120 pu. pplying the differential equation model: (dA/dt) = kA, (k>0) pproximately, how long do the residents of this city have before the dangerous limit is reached? Choose all correct answers. A Less than 12 years. B) More than 9 years. D Less than 10 years. More than 11 years.

Question
According to a recent data analysis, the amount A(t) of atmospheric pollutants in a certain city is found to approximately quadruple every 9.5 years. The current amount of pollution in this city is 25 pu (pollutant units), and it is considered to be dangerous to stay in the city when the amount of pollutants reaches 120 pu. Applying the differential equation model: (dA/dt) = kA, (k>0) approximately, how long do the residents of this city have before the dangerous limit is reached? Choose all correct answers. A Less than 12 years. B More than 9 years. Less than 10 years. More than 11 years.
