Part c if you accidentally spill phosphorus-32 onto your shoe, how long would it take before 99.9% of the radioactive material has decayed so that you can safely wear the shoes again? express your answer as an integer. view available hint(s)

Step-by-step explanation:

The half-life of the phosphorus-32 is 14.3 days. The time constant of the isotope is:

The decay formula is:

The time related to the decayed proportion of the radioactive isotope is:

the answer to the question is a  

it has the same slope and the same y-intercept.

v = 1/3 a^2h

step-by-step explanation:

if the height is 57.7cm and the height of the slant edge is 18.2cm, then the volume is 1/3 a^2h.
