Anyone want to help me out with this?? The function f(t) = 8100(0.993) 365 represents the change in a quantity over t
days. What does the constant 0.993 reveal about the rate of change of the quantity?
The function is
exponentially at a rate of
% every

Evaluate 4 a for a = 5 2/3 . express your answer in simplest form.

The rate of decay of a radioactive substance depends upon the amount present initially. the mass y (mg) of the radioactive substance cobalt-60 present in a sample at time t (years) is represented by the exponential equation y=50e −0.1315 t . answer the following questions in complete sentences. 1. how does the exponential equation above compare to the equation for simple interest that is compounded continuously? explain the similarities. 2. what is the initial amount of cobalt-60 in the sample? 2. how much cobalt-60 is left after 8.4 years? show your work. 3. what would be the y-intercept of the graph? what does it represent? 4. after how many years will the amount of cobalt-60 left be 6.25 mg? explain what happens to the cobalt-60 after 50 years? 5. discuss some “real-world” examples and uses of cobalt-60

Icould really use some with this question.
