Explain how you know which one is the slowest three runners are training for a marathon. One day, they all ran about 10 miles, each of their own constant speed. Which graph shows how long in minutes it takes Runner 1 to run X miles. the equation that relates to runner 2's distance in miles with time in minutes is T equals 8.5 d. runner 3's information is in the table: distance (miles) time(minutes)
2 18
4 36
6 54
8 72
10 90

answer: yes i agree that you should not put it on/p>

step-by-step explanation: the reason for this is that it wastes other peoples time and also make them fail as well and that is never good.

answer: i don't understand it

step-by-step explanation: sorry

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.

-22

times both sides by 2, times () by 8, add alile terms, move terms, add alike and caculate divide both sides by 3
