- The relation T= 190(2) 16 can be used to determine the length of time, t, in hours, that milk of a certain fat content will remain fresh.
T'is the storage temperature, in degrees Celsius.
a) What is the freshness half-life of milk?
b) Graph the relation.
How long will milk keep fresh at 22°C? at 4°C?

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.
