Suppose an Egyptian mummy is discovered in which the amount of carbon-14 present is only about - the amount found in living human beings. The amount of carbon-14 present in animal bones after t years is given by y, where is the amount of carbon-14 present in living human beings. About how long ago did the Egyptian die?

7.2.47 The half-life of carbon-14 is 5730 years. A frozen human mummy was discovered in a glacier. It was estimated that this human died 5100 years before he was discovered in the melting glacier. How much of the original carbon-14 remained in the mummy at the time of his discovery? The frozen human has about % of the carbon-14 expected in living matter.

The wrappings from a mummy discovered in an Egyptian tomb in the Valley of Kings was dated by counting its 14C content. 14C decays by a first-order process with a half-life of 5730 years. A) What is the rate constant, k, for the decay of carbon-14? Show your work, including units and the equation you used. B) The mummy wrappings were found to have 75% of the 14C activity/gram that one would expect to find in a modern artifact. What...

The half-life of carbon-14 is 5600 years. If a piece of charcoal made from the wood of a tree shows only 74% of the carbon-14 expected in living matter when did the tree die? The tree died about years ago (Do not round until the final answer Then round to the nearest whole number.)

At an archaeological dig, the remains of a saber-tooth tiger are found. In a carbon dating ( 14C has a half-life of 5730 years) test to calculate the age of the cat, a scientist finds that the amount of 14C is about 1/32 the amount of 14C in living animals. How long ago did this saber-tooth tiger die?
