Casey does for a bike ride from exeter to durham, while an odometer keeps a cumulative record of a number of miles traveled. the equation m=12t+37 describes the odometer reading m and t hours of riding. what is the meaning of 12 and 37 in the context of this trip?

37 is the amount the odometer had already have read before the bike ride started.

12 miles is the amount of miles rode in 1 hour. (as t, or time = hour)

the answer is a i belaeve atleast thats what my calculator just gfave me

step-by-step explanation:

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.
