Find the value of f(x) = [2.7] a. 2 b. 2.7 c. 3
1 answer:
The correct answer is A.
EXPLANATION
The given function is called the greatest integer function.
That is
f(x)=[x]
f(2.7)=[2.7]=2
The input is 2.7, the output
is the greatest integer that is less than or equal to 2.7
All integers less than 2.7 are
The greatest of all of them is 2.
In programming... The int variable behaves like this function.
int(2.7) will give you 2
Simply put that function gives you the integer part of whatever is in it.

I believe you are referring to the half-life formula, which is used to calculate the half-life (when the substance drops to half of its original amount) of radioactive substances. The equation is as follows: 
<em>A</em> is the remaining amount
<em>P</em> is the initial amount
<em>t</em> is the time that has passed
<em>h</em> is the half-life of the substance
When plugging values into the equation, make sure that <em>t </em>and <em>h </em>are both measured in the same unit (e.g. <em>t </em>days and <em>h </em>days), as well as <em>A </em>and <em>P</em>.
