***Understanding Carbon-14 Decay: The Case of the Shroud of Turin***

The radioactive isotope carbon-14 is present in small quantities in all life forms and is constantly replenished until the organism dies, after which it decays to stable carbon-12 at a rate proportional to the amount of carbon-14 present. With a half-life of 5598 years (half-life is how long it takes for half of the carbon-14 to decay). Suppose \(C(t)\) is the amount of carbon-14 present at time \(t\).

**Step 1: Determining the Decay Constant**

Find the value of the constant \(k\) in the differential equation \(C' = -kC\):

\[k = \_\_\_\_\_\] help (numbers)

**Step 2: Estimating the Age of the Shroud of Turin**

In 1988, three teams of scientists found that the Shroud of Turin, which was reputed to be the burial cloth of Jesus, contained about 91 percent of the amount of carbon-14 contained in freshly made cloth of the same material [1]. How was old the Shroud of Turin in 1988 according to these data?

\[Age = \_\_\_\_\_ \text{ years}\] help (numbers)
