Situation: A 48 gram sample of a substance that's
used for drug research has a k-value of
0.1371.
Find the substance's half-life, in days.
Round your answer to the nearest tenth.
Enter the correct answer.
N = Noe
-kt
DONE
No = initial mass (at time t = 0)
ĐOO
GO
N = mass at time t
k = a positive constant that depends on
the substance itself and on the units
used to measure time
t = time, in days

solution:

the given function is ,

      =

the three roots of this quadratic function is , 0 ,8 and 10.all the roots are real and rational.

if a quadratic equation is of the form ,

sum of the roots = a + b +c= 0+8+10=18=  

product of roots taken two at a time = a b + b c+ c a = 0+80+0=80 =  

product of roots = a b c = 0=  

there are 11 doors in a hall starting from 0 to 11.the entry in the hall is permitted through gate number 0 and exit is allowed through only gate number 8 and 10.so, three roots(0,8,10) of quadratic function is given by entry and exit route of this hall.
