A student in greece discovers a pottery bowl that contains 29% of its original amount of C-14

The age of the pottery bowl is 12,378.7 years

Step-by-step explanation:

The amount of C-14 after t yeas is given by the following equation:

In which N(0) is the initial amount and k is the decay rate.

In this question, we have that:

So

Age of the pottery bowl:

29% of its original amount of C-14. So we have to find t for which N(t) = 0.29N(0). So

The age of the pottery bowl is 12,378.7 years

17 1/3

step-by-step explanation:

graph b

step-by-step explanation:

one solution- graph a (clear intercepting point.)

no solution- graph b (they're parallel, there will never be a point of interception.)

infinite solutions- graph c (all points intercept.)
