Question 1078034: problem: Doctors use radioactive iodine as a tracer in diagnosing certain thyroid gland disorders. This type of iodine decays in such a way that the mass remaining after t days is given by the function
m(t) = 2e^−0.087t
where m(t) is measured in grams.
(a) Find the mass at time t = 0. grams
(b) How much of the mass remains after 2 days? (Round your answer to three decimal places.)

m%28t%29=2e%5E%28-0.087t%29
-

(a)
If t=0, then m=2.

(b)
If t=2, for two days,
then m%282%29=2e%5E%28-0.087%2A2%29.
m(2)=1.68
