I can recognize proportional relationships using tables and graphs. I can calculate rates and unit rates.
1. Which set of ordered pairs represents a proportional relationship between the x and y values?
A. (0, 0), (1, 2), (2, 4)
B.
(0, 0), (1, 2), (3, 4)
C.
(0, 0), (1, 2), (2, 1)
D. (0, 0), (1, 2), (3,9)

cosine

step-by-step explanation:

it’s supposed to be -4+45=41

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.
