Question

Find the decay constant. Please help!

Answer 1

Technetium-99m, a radioisotope used to image the skeleton and the heart muscle, has a half-life of about 6 hours.

Find the decay constant. Use the decay function \[N(t) = N_{0} e ^{-kt}\] to determine the amount of a 250 mg dose that remains after 24 hours.

Answer 2

@phi, @austinL can you help?

Answer 3

In your decay function, can you assign numbers to any of the variables, from the data given in the question?

Answer 4

No, this one is more complicated than any of the ones I had learned. It kinda came out of nowhere. Can you run me through it @phi?

Answer 5

Any guess what N stands for ?

Answer 6

what do you think "t" stands for ?

Answer 7

Would N stand for 24 and (t) stand for 6?
