Suppose an Egyptian mummy is discovered in which the amount of carbon-14 present is only about two-fifths the amount found in living human beings. The amount of carbon-14 present in animal bones after t years is given by y = yo e0.0001216t where yo is the amount of carbon-14 present in living human beings. About how long ago did the Egyptian die? About yr ago the Egyptian had died.
