The 1985 explosion at a nuclear lab sent about 1000 kilograms of a radioactive element into the atmosphere. The function f(x)=1000(0.5) describes the amount, f(x), in kilograms, of a radioactive element remaining in the area x years after 1985. If even 100 kilograms of the radioactive element remains in the atmosphere, the area is considered unsafe for human habitation. Find f(40) a determine if the area will be safe for human habitation by 2025.
