Answer 1

The amount of carbon-14 present after 6834 years is approximately 7 grams

Using the exponential model given ;

• 
  `A = 16e^(-0.000121t)`

Given a t value of : 6834

Substitute t = 6834 into the expression ; we have ;

`A = 16e^(-0.000121 * 6834)`

`A = 16e^(-0.000121 * 6834)`

`A = 16e^(-0.826914)`

`A = 16 × 0.4373970129`

`A = 6.9983`

The amount of carbon-14 present after 6834 years is approximately 7 grams
