Amachine fills quaker oatmeal containers with 32 oz. of oatmeal. after the containers are filled, another machine weighs them. if the containers weight differs from the desired 32 oz. weight by more than 0.5 oz., the container is rejected. write an equation that can be used to find the heaviest and lightest acceptable weights for the quaker oatmeal container.

We know that ideally a Quaker oatmeal container should have 32 oz. oatmeal.

We also know that a difference of 0.5 oz. is acceptable, otherwise the container is rejected.

Let the amount of oatmeal actually present in the container be Q

32 - 0.5 < Q < 32 + 0.5

⇒ 31.5 < Q < 32.5

Hence, the equation that represents the highest and lightest acceptable weights is 31.5 < Q < 32.5.

i would say c is the best answer, hope it's right!

good luck! =)

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.
