She earns $1454.88 gross pay each month if she works 40 hours a week how much is her hourly rate

$8.36

Step-by-step explanation:

there are 4.35 weeks in 1 month,

each week is 40 hours, so 4.25*40=174 hours total,

to find hourly rate we have to divide the whole pay by hours,

1454.88/174 = 8.36137931034 = 8.36

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.
