A researcher begins a study with 1,400 mg of a certain radioactive material. The material has a half-life of 1 day, meaning that after 24 hours one half of the atoms in the sample have disintegrated. The amount in the sample after n days is given by the recursive formula A(n)= 1
2•A(n−1). How much of the material will be left in the sample after 7 days?
After 7 days, nothing mg of the material will be left in the sample.
(Simplify your answer.)

answer rather than having to add and subtract the measurements of the semi-circle, notice that the semicircle to the left of ad is actually identical in area to the blank semicircle-shaped space to the left of bc. so if we transferred the red semicircle into the blank space, we would end up with a square of side length 24 cm. the area of a square is s^2 = 24^2 = 676 cm^2.
