Question 1010625: Cesium-142 has a half life of 50 years. If there are 20 grams now:
a. Fill in the equation y=ab^x
b. Find the growth factor (b) for this exponential function
Answer by josgarithmetic(39620) (Show Source): You can put this solution on YOUR website!
You have only one datum point in the half-life information, and then a value for making a question. Why not the basic exponential decay equation like ?
Try your simpler format anyway.
Half-life information would seem to make , using a for the initial quantity of Cs-142.
....
The model being , using a as the initial quantity.
This b value is not a growth factor!! The "growth" is negative, not positive.
Having "twenty grams now", you can write .
