Judy works at a candy factory that makes sugar rush candy bars. she is in charge of quality control and has to make sure each candy bar has the correct mass. each candy bar is required to weigh 12 grams, with a tolerance of 0.45 grams. what is the acceptable weight range for each candy bar? 1. define a variable for this situation.2. write the absolute value inequality that describes the acceptable weight range for each candy bar. 3.using words, describe the possible acceptable weight range for each candy bar.

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.
