IM Mathematics 3. A chef bought $17.01 worth of ribs and chicken. Ribs cost 1.89 per pound and chicken
costs 0.90 per pound. The equation 0.9c+1.89r = 17.01 represents the relationship
between the quantities in this situation.
Show that each of the following equations is equivalent to 0.9c+ 1.89r = 17.01.
Then, explain when it might be helpful to write the equation in these forms.
a. c= 18.9 -2.1r
b. r=-*c+9

step-by-step explanation:

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.
