Use a calculator with a y x key or a ∧ key to solve Exercises 65-70. The 1986 explosion at the Chernobyl nuclear power plain in the former Soviet Union sent about 1000 kilograms of radioactive cesium-137 into the atmosphere. The function f ( x ) = 1000 ( 0 ⋅ 5 ) r 30 describes the amount, F ( x ), in kilograms, of cesium-137 remaining in Chernobyl x years after 1986. If even 100 kilograms of cesium-137 remain in Chernobyl’s atmosphere, the area is considered unsafe for human habitation. Find f (80) and determine if Chernobyl will be safe for human habitation by 2066.

describes the amount, F (x ), in kilograms, of cesium-137 remaining in Chernobyl x years after 1986. If even 100 kilograms of cesium-137 remain in Chernobyl’s atmosphere, the area is considered unsafe for human habitation. Find f (80) and determine if Chernobyl will be safe for human habitation by 2066.
Write the domain of the given function using interval notation: f(x)= (square root of x)-93
Why is the answer [0,infinity)?
After declining between 1940 and 1980, the number of multigenerational American households has been increasing since 1980. The function h(x) = 0.012x2 – 0.583x +35.727 can be used to estimate the number of multigenerational households in the United States, in millions, x years after 1940.
In what year were there 40 million multigenerational households?
The value of China's exports of automobiles and parts (in billions of dollars) is approximately f(x) 1.8208e^.3387x where x-0 corresponds to 1998.
In what year did/will the exports reach 59.5 billion?
Give your answer as the year, with at least one decimal place
