A chemist measures 8 grams of a substance that

has a half-life of 6 hours. Which equation models

the weight, y, of the substance after 15 hours?

Where b is the decay rate for this case. Using the condition given we have:

And our model would be given by:

And replacing the value of t=15 we got:

Step-by-step explanation:

For this case since the half life is 6 hours we have the following condition:

Where is the initial amount

Our model for this case is given by this expression:

Where b is the decay rate for this case. Using the condition given we have:

And solving for b we got:

And solving for b we got:

And our model would be given by:

And replacing the value of t=15 we got:
