The rate at which the mass of a substance decreases because of radioactive decay is modeled by the function
A(t) = 200(4).
A(t) represents mass, in grams, and t represents time, in days.
Which three statements correctly describe this function?
O When A(3) = 25, the 3 represents 3 days and the 25 represents 25 grams.
O When A(3) = 25, the 3 represents 3 grams and the 25 represents 25 days.
G The dependent variable is A(t).
D The dependent variable is t.
The independent variable is A(t).
O The independent variable is t.
