carbon 14, an isotope of carbon decays at a rate propotional to the amount present and have a halflife of 5730 yrs. (a) what percentage will remain after 5730 yrs? (b) how can u interpret the formula P=P0e^kt, so that we can use the data? what variable do we no know? (c) use the data, your new interpretation of the formula and logarithims to find the rate of decay and the missing variables? (d) Create a graphical representation of the function. (e) at t=7321yrs, what percentage of isotope is remaining? (f) how many yrs from t=0 must pass for there to be 37% of the isotope remaining?
