Question
![**Radioactivity Decay Problem**
The radioactivity of an element decreases by 72 percent in 820 days.
(a) Determine the half-life of the element, rounded to a whole number:
[ Input Field ]
(b) Determine the number of days, rounded to a whole number, for a sample of 100 mg to decay to 61 mg:
[ Input Field ]
*Note: This problem involves calculations related to exponential decay and half-life. To determine the half-life, you will use the decay percentage over the given period. For part (b), apply the exponential decay formula using the initial and final amounts.*](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F03fe9005-e4ff-463e-865c-c8d9bf55cd04%2Fd02ea55c-76bc-4a84-aa42-26a56836012e%2F2xxei79_processed.png&w=3840&q=75)
