Complete the table for the radioactive isotope. Half-life Initial (years) Quantity Amount After Isotope 1000 Years 14C 5715 46.5 g Step 1 Recall that the exponential model is y = Cekt In this case the time taken to halve the original amount is 5715 years. Substitute the values of y and t in the equation. 10000 Divide both sides of the equation by C. Submit Skip (you cannot come back)
