Question

Iodine-131 is an isotope that is used to study the functioning of the thyroid gland. This isotope has a half-life (time required for half the material to erode) of approximately 5 days. If a patient is given an injection that contains 5 micrograms of iodine-131, what will be the iodine level in the patient after 9 days? Use the function where A is the amount of the isotope, in micrograms, in the patient after t days.
