Unformatted text preview: is estimated to be only 42% of the original amount, approximately how old is the tool? (d) Radiocarbon dating is not as easy as these exercises might lead you to believe. With the help of your classmates, research radiocarbon dating and discuss why our model is somewhat over-simplified. 21 Awesome pun! 392 Exponential and Logarithmic Functions 6. Carbon-14 cannot be used to date inorganic material such as rocks, but there are many other methods of radiometric dating which estimate the age of rocks. One of them, RubidiumStrontium dating, uses Rubidium-87 which decays to Strontium-87 with a half-life of 50 billion years. Use Equation 6.5 to express the amount of Rubidium-87 left from an initial 2.3 micrograms as a function of time t in billions of years. Research this and other radiometric techniques and discuss the margins of error for various methods with your classmates. 7. Use Equation 6.5 to show that k = − ln(2) where h is the half-life of the radioactive isotope. h x 8. In Example 6.1.1 in Section 6.1, the exponential function V (x) = 25 4 was used to model 5 the valu...
