The radioactive substance uranium-240 has a half-life of 14 hours. the amount a(t) of a sample of uranium-240 remaining (in grams) after t hours is given by the following exponential function. at = 3900(1/2) t/14 find the initial amount in the sample and the amount remaining after 40 hours. round your answers to the nearest gram as necessary. asap

To solve this problem, we just need to substitute the right value for the variable time.

The given expression is

Where the initial condition is determined when .

Therefore, the initial amount is 3900 grams.

Then, after 40 hours refers to

Therefore, after 40 hours, there's 538.24 grams remaining, approximately.

idk but i found this "the graph of y = f(x-2) is the graph of y = f(x) translated two units rightward.  

so, since the point (9,2) lies on the graph of y = f(x), the point (11,2) lies on the graph of y = f(x-2)."
