Prehistoric cave paintings were discovered in a cave in France. The paint contained 20% of the original carbon-14. Use the exponential decay model for carbon-14. A=A 0 e^ -0.000121t estimate the age of the paintings

{0,1,2,3,4,5,6,20,21,22,23,24,25} the distribution is considered to be: skewed the right, skewed the left, not skewed?

1- what do you think the product of a nonzero rational number and an irrational number is? is it rational or irrational? make use of variables, the closure property of integers, and possibly a proof by contradiction to prove your hypothesis.2- why do we have to specify that the rational number must be nonzero when we determine what the product of a nonzero rational number and an irrational number is? if the rational number were 0, would it give us the same result we found in the first question?

Consider circle o, where and . m∠bpd °. °.
