Question

The amount of carbon -14 present in 9705 years will be approximately blank grams.

Answer 1

Given

The decay model for the amount of carbon-14 present after t years is,

`A=16e^(-0.000121t)`

To find the number of carbon-14 present in 9705 years.

Step-by-step explanation:

It is given that,

`A=16e^(-0.000121t)`

Then, for t=9705,

`\begin{gathered} A=16e^(-0.000121*9705) \\ =16*0.3090 \\ =4.9445 \\ =5(Rounded\text{ to the nearest whole number}) \end{gathered}`

Hence, the amount of carbon-14 present in 9705 years is 5grams.
