The 1987 explosion at a nuclear lab sent about 1000 kilograms of a radioactive element into the atmosphere. the function f left parenthesis x right parenthesis equals 1000 left parenthesis 0.5 right parenthesis superscript startfraction x over 30 endfraction describes the amount, f(x), in kilograms, of a radioactive element remaining in the area x years after 1987. if even 100 kilograms of the radioactive element remains in the atmosphere, the area is considered unsafe for human habitation. find f(70) and determine if the area will be safe for human habitation by 2057.

answer: solve 5\cdot 2^x=2405⋅2  

x

=2405, dot, 2, start superscript, x, end superscript, equals, 240.

solution

to solve for xxx, we must first isolate the exponential part. to do this, divide both sides by 555 as shown below. we do not multiply the 555 and the 222 as this goes against the order of operations!

\begin{aligned} 5\cdot 2^x& =240 2^x& =48 \\ \end{aligned}
