Juan plotted several ratios that represent the cost of plums at the local grocery store. When he finished his graph, he felt that one of the points was plotted incorrectly.

On a coordinate plane, the points (2, 1), (6, 3), (9, 4) and (12, 6) are plotted.

Which ratio is not equivalent to the others?
2 to 1
6 to 3
9 to 4
12 to 6

9 to 4

9 is an Odd number so it cannot be divided by 2

9 to 4

Step-by-step explanation:

9 is an odd number and is not divisible by two

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.

34.5 cm

step-by-step explanation:

generally for a circular segment of angle, θ° and radius r

arc length

= (θ/360) x circumference

= (θ/360) x 2πr

in our case, θ = 60°, π=3.142 and r = 33 cm

substitute into above formula

arc length

= (60/360) x 2(3.142)( 33) = 34.5 cm
