Question 1161523: An Egyptian mummy is discovered in which the amount of Carbon-14 present is only about twentynine fiftieths the amount found in living human beings. a. Using the half-life of Carbon-14, determine the decay constant for Carbon-14 (answer in decimal form and scientific notation, accurate to the tenth decimal place)? b. About how long ago did the Egyptian die? c. If this is a royal tomb, which Pharaoh is in the sarcophagus? Which dynasty and regnal years are recorded for this Pharaoh?

You could try a model like
A, amount at time x
p, initial amount if x is 0
x, time passage in years
5730, the half-life of Carbon-14, in years

Question part (a) for "decay constant", more like

(To the "tenth" decimal place makes no sense in the given example.)

Part (b):

Either model can be used.
