Prehistoric cave paintings were discovered in a cave in france. the paint contained 24 %24% of the original carbon-14. use the exponential decay model for carbon-14, upper a equals upper a 0 e superscript negative 0.000121 ta=a0e−0.000121t, to estimate the age of the paintings. the paintings are approximately 1179411794 years old. (round to the nearest integer.) question is complete.

t = 11,794 years

Step-by-step explanation:

If you are looking for a confirmation that your answer is correct, it is.

0.3636... repeating = 4/11 .

I just recently learned how to find the fraction
that's equal to a repeating decimal.

-- Take the group of digits that repeats.      (in this one, it's 36)
     Write it on top of the fraction.
                                                               36 /

-- On the bottom of the fraction, write the same number of 9's .

                   For this one, it's           36 / 99 .

-- There's your fraction.
   Simplify it if possible.

           Divide top and bottom of this one by 9:         36/99  =  4/11 .

Is that cool or what !
