Hi can you please help me with this question. Which is the least value of the five numbers below. 11.03. 11.04 11.1. 11.003. 11.02

the greater the number pf Zeroes after the point, the lower the value of the number, so option 11.003

i just took the test, the correct answer is .. 31.5 in.

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.
