. Authorities conducted an investigation and found that. the chemical Trioxln was illegally dumped into the local swamp. Exactly four days after the assumed time of " the crime. the amount at Trloxin in the swamp was estimated at about 45.7 barrels, and exactly seven days after the crime, it was estimated at 21.5 barrels. Assume that no Trioxin was in the swamp before the crime, and that Trloxin decays exponentially. Construct a model that estimates the amount of Trioxin (in barrels) remaining in the swamp t days after it was dumped, then use that model to answer the following. 1) According to the model. how much Trioxln was initially dumped into the swamp? ROUND TO ONE DECtMAL PLACE. About barrels Were initially dumped into the swamp. 2) According to the model. at what rate was the amount at Trioxin in the swamp decreasing exactly 4 days after it was dumped? ROUND TO ONE DECIMAL PLACE. The Trioxin was decreasing at a rate of -barrels per day. 3) How many days after the crime willldid it take for the amount of Trioxin in the swamp to drop to 2 barrels? ROUND TO ONE DECIMAL PLACE. it look or wlll take about 15.03 days
