If w = -4, which inequality is true? Select all the correct answers. A. 2 â€" w < â€"3 B. 5 2w > -7 C. 1 â€" 2w > 13 D. â€"3 â€" 5w < â€"14 E. â€"5 â€" 4w > 10 F. â€"9 â€" 3w < 2.

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.

the answer is 13/48
