Prehistoric cave paintings were discovered in a cave in france. the paint contained 10 %10% of the original carbon-14. use the exponential decay model for carbon-14, upper a equals upper a 0 e superscript negative 0.000121 t=a0e−0.000121t, to estimate the age of the paintings.

t=19188.2 y

Step-by-step explanation:

The exponential decay equation is:

     (1)

But, A is 10% of A₀, it means that A=0.10A₀.

If we put it into equation (1), we will have:

        (2)

Now, we just need to solve (2) for t.

I hope it helps you!    

the answer is thin because within context, the stanza concludes the and frail tone the people have toward each other, and the fact that it would be thin, makes the most sense compared to "pliable" or "not hard or firm to the touch". hope this , good luck.
