A certain radioactive material is known to decay at a rate proportional to the amount
present. If the initially there is 50 milligrams of the material present and after two
hours it is observed that the material has lost 10% of its original mass. Find
a) An expression for the mass of the material remaining at any time t
b) The mass of the material after 4 hours
c) The time rate at which the material has decayed to one half of its initial mass
