A tumor is injected with 0.52 grams of Iodine-125. After 1 day, the amount of Iodine-125 has decreased by 1.15%. Write an exponential decay model with A (t) representing the amount of Iodine-125 remaining in the tumor after t days. Enclose arguments of the function in parentheses and include a multiplication sign between terms. For example, c * In (t). Then use the formula for A (t) to find the amount of Iodine-125 that would remain in the tumor after 8.5 days. Round your answer to the nearest thousandth (3 decimal places) of a gram. sin (a) A (t) = There will be Number grams of Iodine-125 after 8.5 days.

Question
Already had this question answered but I must have put it in wrong because the answer wasn't right
I put 0.52e^(-0.00115t)
so what is A(t)=?
Transcribed Image Text:A tumor is injected with 0.52 grams of Iodine-125. After 1 day, the amount of Iodine-125 has decreased
by 1.15%.
Write an exponential decay model with A (t) representing the amount of Iodine-125 remaining in the
tumor after t days. Enclose arguments of the function in parentheses and include a multiplication sign
between terms. For example, c * In (t).
Then use the formula for A (t) to find the amount of Iodine-125 that would remain in the tumor after
8.5 days. Round your answer to the nearest thousandth (3 decimal places) of a gram.
sin (a)
A (t) =
There will be Number
grams of Iodine-125 after 8.5 days.
