TRAIN TICKET PRICES Adult
Child
To Zone 2 $9.75 $6.50
To Zone 3 $12.75 $8.50
To Zone 4 $15.00 $10.00

Which statement describes the relationship between the adult ticket prices, a, in dollars, and the
child ticket prices, c, in dollars?
A) The relationship is not proportional. The change in a is not constant, and
therefore the relationship cannot be expressed as one equation.
B). The relationship is proportional. It can be represented as a =
C) The relationship is not proportional. The change in c is not constant, and
therefore the relationship cannot be expressed as one equation.
D) The relationship is proportional. It can be represented as a

step-by-step explanation:

the smallest possible measurement of the width is 14 feet

step-by-step explanation:

let's assume length of parallelogram is 'l'

width of parallelogram is 'w'

the perimeter of a parallelogram must be no less than 40 feet

so, we get

we are given

length of parallelogram is 6 feet

so,

l=6

we can plug it

now, we can solve for w

subtract both sides by 12

divide both sides by 2

and we get

so,

the smallest possible measurement of the width is 14 feet

figure c

step-by-step explanation:

hope this .

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.
