A radioactive substance decays from 50 mg to 14 mg in 28 years according to the exponential decay model y = ae-bz, where a is the initial amount and y is the amount remaining after r years. Find the b -value. Round to the nearest hundredth, if needed. Use the EXACT b-value to write the exponential decay model for this substance with initial amount 50 mg. Use that model to find the half-life. Round to the nearest hundredth of a year, if needed. half-life 2 years

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.
