A tumor is injected with 0.72 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*ln(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.   A(t)=   There will be   grams of Iodine-125 after 8.5 days.

Differential Equations

Have you ever observed the movement of the satellites and rockets or how the planets go around the sun in their orbits? How will you determine their motion? Definitely they follow some scientific laws and these kinds of problems are framed as differential equations.
