The decimal d is formed by writing in succession all the positive integers in increasing order after the decimal point; that is, d = 0.123456789101112 . . what is the 100th digit of d to the right of the decimal point?
(a) 1
(b) 0
(c) 5
(d) 8
(e) 9

C. 5.

Step-by-step explanation:

There are 9  1 digit numbers, then  from 10 to 19 we have another 20 digits

then 20 to 29 is another 20 digits.

29 digits  give 9 of 19

49 digits give 9 of 29

69 digits give 9 of 39

89 digits give 9 of 49

99 digits give 4 of  54

100 digits give 5.

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.
