Iron-59 has a half-life of 44.5 days. How much of a 3.00 mg sample will be left after 222.5 days?

answer: 0.26

i used the calculator on google

since we know that the two functions are equal, f (x) = g

(x), therefore when we equate the two equations the result should be similar to

3x = x – 4:

a. f(x) = 3x, g(x) = x – 4

equating the two functions:

3x = x – 4             (correct)

so we now got our answer (a)

the answer for this is 0.25 km. : )
