Question
Hello, 
May you please help with this problem thank you I appreciate it. 
 
In 1986, the worst nuclear disaster occurred in Chernobyl, USSR, when an explosion at a nuclear power plant released 1000 kg of radioactive cesium-137. The following model calculates the remaining amount of cesium-137 in the atmosphere years after 1986. 
 
 
 
Find for the following: 
     Year
x (years since 1986)
          f(x)
2006
20
 
2026

2046
60
 
2066
80
 
2086
100
 
2106
120
 
2126
140
 
 
If 100 kg or more of cesium-137 is considered unsafe for humans, when will this area be safe again (you may give an estimate based on your table of values above or find the exact value from a graphing utility)? What is the y-intercept for this function and what does it represent? Is this a growth or decay function?
