Answer:
No, is not a function.
Step-by-step explanation:
To find : Is a function ?
Solution :
A function is defined as a relation between sets that associates to every element of a first set exactly one element of the second set.
or relation between input and output.
i.e. f(x)=2x
Where, x is the input and 2x is the output.
We have given, is not a function because it is not a representation of function.
The given expression is an equation as there is only one variable defined as a constant.
Answer:
the time taken for the radioactive element to decay to 1 g is 304.8 s.
Step-by-step explanation:
Given;
half-life of the given Dubnium = 34 s
initial mass of the given Dubnium, m₀ = 500 grams
final mass of the element, mf = 1 g
The time taken for the radioactive element to decay to its final mass is calculated as follows;
Therefore, the time taken for the radioactive element to decay to 1 g is 304.8 s.
