1. The state of decay of radium is proportional to the amount present at any time Suppose that 400 mg of radium are currently present, and the amount decreases after every hour. After 1 hour, it decreases to 295. How much radium will be left after 2.5 hours if the decrease in number is constant?
When you are dealing with any Calculus 2 homework, it is vital to have a look at the various questions and answers that will help you see whether you are correct in your approach to finding solutions. Even if you are dealing with analytical aspects of Calculus 2, it will be helpful as you are looking at provided equations and learn how the answers relate to original questions and problems specified.
Do not be afraid to take a look at the basic integration and related application if Calculus 2 does not sound clear or start with the Calculus 1 first.
