Agarden hose fills a 2-gallon bucket in 5 seconds.
the number of gallons, g, is proportional to the number of seconds, t, that the water is running.
which equation represents the relationship between g and t? select all that apply.
a. g = 0.4t
b. t = 0.4g
c. g = 2.5t
d. t = 2.5g
e. g = 2/5t

answer: h

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.
