Graph f −1, the inverse of f . The radioactive substance uranlum-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 glven by the following exponential function. A(t) = 2800(21)14t Find the initial amount in the sample and the ...
WebSo remember, when half-life-- when time is equal to a half-life, right, the number of radioactive nuclei, this would be, let's see one half-life, so this would be the initial divided by two. So half of it remains. So let's look at that on our graph, right, so if we take N naught, we divide that by two, that's approximately here, so let's say ... WebCarbon-14 has a half-life of about 5,700 years. When a living thing dies, it stops absorbing carbon-14. This means the amount of carbon-14 will decrease over time. ... A graph showing how the ...
