Four students provide the following approximations for
0.89
Anyah states that Jo 89 is between 0.44 and 0.45 because 0.44 < .00 <0.45
Matthew states that V0.89 is between 0 and 1 because I <0.89 <1.
Rhoda states that V0.89 is between 0.9 and 10 because 0.92 <0.89 <1.02.
Ming states that 0.89 is between 0.93 and 0.95 because (0.93)2 <0.89 <(0.95).

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.
