2tickets @ $24.95 total $64.50
let f represent the cost of ordering each ticket online. write an expression that could be used to find the cost of ordering each ticket.

The expression is F=(Total cost)-2(cost of each ticket)

Step-by-step explanation:

Given the cost of two tickets each @ $24.95. Also total cost will be $64.50

Let F represent the cost of ordering each ticket online.

we have to write the expression that could be used to find the cost of ordering each ticket.

As, the sum of cost of ordering tickets online and the cost of two tickets gives the total cost i.e

F+2(cost of each ticket)=Total cost

F=(Total cost)-2(cost of each ticket)

F=Total cost-2($24.95)

Now, solving above we get the F, the cost of ordering each ticket.

⇒ F=$64.50-2($24.95)=$14.6

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.
