What is the inverse of the statement “if i do not buy a ticket, then i do not go to the concert”? if i buy a ticket, then i go to the concert. if i do not go to the concert, then i do not buy a ticket. if i buy a ticket, then i do not go to the concert. if i go to the concert, then i buy a ticket.

Answer-

The inverse of the statement “If I do not buy a ticket, then I do not go to the concert" is "If I buy a ticket, then I go to the concert."

Solution-

In order to form the inverse of any conditional statement, we have to take the negation of both the hypothesis and the conclusion.

In this case, the hypothesis is, "if I do not buy a ticket"

And the the conclusion is, "then I do not go to the concert"

The negation of the hypothesis would be - "if I buy a ticket",

And the negation of the conclusion would be - "then I go to the concert"

Therefore, the inverse of the statement “If I do not buy a ticket, then I do not go to the concert" is "If I buy a ticket, then I go to the concert."

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.
