Authorities conducted an investigation and found that the crime. the amount of Trioxin in the swamp was estimated at about 399 barrels. and exactly seven the chemical Trioxin was illegally dumped into the local swamp. Exactly four days after the assumed time of days after the crime, it was estimated at 29.9 barrels. Assume that no Trioxin was in the swamp before the Crime. and that Trigxin 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 Trioxin was initially dumped into the swamp? ROUND TO ONE DECIMAL PLACE. About El barrels were initially dumped into the swamp. 2) According to the model, at what rate was the amount of Trioxin in the swamp decreasing exacti y 4 days after it was dumped? ROUND TO ONE DECIMAL PLACE. The Trioxln was decreasing at a rate of Dbarrels per day. 3) How many days after the crime will/did it take for the it took or will take about Ddays. amount of Trioxin in the swamp to drop to 2 barrels? ROUND TO ONE DECIMAL PLACE
