One type of Iodine disintegrates continuously at a constant rate of 8.6% per day.
Suppose the original amount,, is 10 grams, and let be measured in days.
Because the Iodine is decaying continuously at a constant rate, we use the model
for the decay equation, where k is the rate of continuous decay. Using
the given information, write the decay equation for this type of Iodine.
