3. A liquid starts at a temperature of 182 °F and cools down in a room held at a constant 68 °F. After 20 minutes of cooling, it is at a temperature of 80 °F. The Fahrenheit temperature, F, can be modeled as a function of time in
minutes, t, by the equation:

F(t)=a(b)^t+c

the answer is: the length is 5/6 yards.

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.
