In one weekend, a theatre sells 74,877 tickets to a new movie. write the values for each of the 7s in 74,877

Answer and Explanation:

Given : In one weekend,a theatre sells 74,877 tickets to a new movie.

To find : Write the values for each of the 7s in 74,877 ?

Solution :

The place value system is

Ten thousand    Thousand     Hundred     Tens    Ones

        7                      4                8                7           7

The value of 7 at ten thousand place is

The value of 7 at tens place is

The value of 7 at ones place is

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.
