Answer:
4
Step-by-step explanation:
8-4=4
Answer:
With the initial amount and t the time on hours and t the time in hours. since the half life is 12 hours we can find the parameter of decay like this:
And solving for b we got:
And then we have:
And the model would be given by:
Step-by-step explanation:
Assuming this complete question: "A specific radioactive substance follows a continuous exponential decay model. It has a half-life of 12 hours. At the start of the experiment, 82.6g is present.
"
For this case we can create a model like this one:
With the initial amount and t the time on hours and t the time in hours. since the half life is 12 hours we can find the parameter of decay like this:
And solving for b we got:
And then we have:
And the model would be given by:
Answer:
9 3/4
Step-by-step explanation:
3 1/4+6 1/2=
9+ 3/4
the answer is 9 3/4
