Step-by-step explanation:
The amount of carbon-14 is modeled by the following equation:
In which is the initial amount and k is the rate of decrease.
(a) Find the value of the constant k in the differential equation.
Half-life of 5595 years.
So
Applying ln to both sides
b) 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. How old is the Shroud of Turin, according to these data?

Step-by-step explanation:
I’m pretty sure it’s A but I would just work it out to make sure
2(2x) + 2(10x + 24) = 360
use the distributive property
4x + 20x + 48 = 360
combine like terms
24x + 48 = 360
subtract 48 from both sides
24x = 312
divide both sides by 24 to isolate the variable x
x = 13
The correct answer is A. 13.
