- A Radioactive Material Disintegrates At A Rate Proportional To The Amount Currently Present If Q Is The Amount Presen 1 (14.4 KiB) Viewed 14 times
A radioactive material disintegrates at a rate proportional to the amount currently present. If Q() is the amount present at times, then dQ dt = -rQ where r> 0 is the decay rate. If 400 mg of a mystery substance decays to 81.54 mg in 2 weeks, find the time required for the substance to decay to one-half its original amount. Round the answer to 3 decimal places. weeks
