The mass of a radioactive substance follows a continuous exponential decay model, with a decay rate parameter of 9% per day. A sample of this radioactive substance has an initial mass of 4.25 kg. Find the mass of the sample after two days. Round your answer to two decimal places.
Note: This is a continuous exponential decay model.
And though the decay rate parameter is 9% per day, the actual decay is not 9% each day.
