The mass of a radioactive substance follows a continuous exponential decay model, with a decay rate parameter of 7% per day. A sample of this radioactive substance was taken two days ago. If the sample has a mass of 3 kg today, find the initial mass of the sample. Round your answer to two decimal places. Note: This is a continuous exponential decay model.And though the decay rate parameter is 7% per day, the actual decay is not 7% each day.

Differential Equations

Have you ever observed the movement of the satellites and rockets or how the planets go around the sun in their orbits? How will you determine their motion? Definitely they follow some scientific laws and these kinds of problems are framed as differential equations.
