Amarathon is about 26 miles long. which of these shows how to convert 26 miles to feet?

The answer in feet is 137280 feet.

Step-by-step explanation:

The relation between miles and feet is given as:

1 mile = 5280 feet.

As we have been given, a marathon is about 26 miles long.

We need to convert 26 miles to feet.

So, the answer in feet will be = = 137280 feet.

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.
