Question 3. faye is selling floral arrangements. each arrangement uses 1 vase and 14 daisies. each vase costs faye $3.00. let c be the total cost of the arrangement and d be the cost of 1 daisy. which equation should faye use to find the total cost of each arrangement?
(points : 1)
c = 3d + 14
c = 14d + 3
14 = c +2d
14c = d + 3

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.
