Answer:
16,383.33 years ( approx )
Step-by-step explanation:
Given equation that shows the amount of carbon-14 after t years,
Where,
= initial amount,
∵ 14% of =
=
Taking ln both sides,
Hence, the painting would be 16383.33 years old ( approx )
Answer:
Step-by-step explanation:
We can see that the graph cuts the x axis at , (-1,0) and y axis at (0,1) . So we can find the slope as ,
f(x) =
note the range is {1, 5, 25, 125 } which can be expressed as
{ ,
,
,
}
the exponents being the domain { 0, 1, 2, 3 }
thus f(x) = an exponential function
