Given:
The original amount of radium is
mg.
The given half-life period is
years.
a) The expression for the radium after the given time is,
In the formula above, replace t and the specified numbers with 6 instead.
In the formula above, replace t and the specified values with 3 instead.
In the formula above, replace t and the specified values with 1 instead.
Thus, the amount of radium after 6 years is 0.75 mg, the amount of radium after 3 years is 1.060 mg, and the amount of radium after 1 year is 1.336 mg.
b) The expression for the radium after the given time is,
Substitute 6 for , and 1.5 for in the above expression.
Thus, the function that represents the amount of radium left after t time is
