A) Radioactive elements such as phosphorus-32 and

A) Radioactive elements such as phosphorus-32 and vanadium-48 decay into other elements over time. The function P (t) = 80(0.953)^t represents the amount of a sample of phosphorus-32, in grams, after t days. The function V (t) = 70(0.958)^t represents the amount of a sample of vanadium-48, in grams, after t days. How does the rate of decay for phosphorus-32 compare to the decay rate of vanadium-48? The sample of phosphorus-32 decays at a faster rate because there are 80 grams in the sample, but there are only 70grams of the vanadium-48 sample. The sample of vanadium-48 decays at a faster rate because its decay rate is 95.8% per day, and the decay rate for the sample of phosphorus-32 is 95.3% per day. The sample of phosphorus-32 decays at a faster rate because it decays by 80% per day, and the sample of vanadium-48 decays by 70% per day. The sample of phosphorus-32 decays at a faster rate because it decays by 4.7% per day, and the sample of vanadium-48 decays by 4.2% per day.
