Radioactive cesium -137 has a wide variety of uses and is commonly used in hospitals for diagnosis and treatment, and to sterilize medical equipment. The formula below shows how 100mg of this substance decays over time,
A(t)=100(0.9775)^(t).
a) Let A=A(t) represent the amount of cesium-137 left, measured in milligrams, after t years. How much of the substance is left after 15 years? Round decima to two places.
etermine the half-life (how long it takes for the amount to be half) of cesium-137. Round two places.
