Which situation could be represented by the graph?

a. students in the children’s choir are at least 8 years old but no more than 11 years old.
b. babysitters earn between $8 and $11 per hour.
c. a program at a community college can be completed in no fewer than 8 months, but must be completed in less than 11 months.
d. the dogs at a veterinary clinic are all 8 years old or under or are older than 11 years.

The correct option which resembles with the given graph is .

Further explanation:

From the given graph the it is observed that the interval is which is a half open interval or it can be said that it is a half closed interval.

A half closed or a half open interval is an interval in which one end point of the interval is included but the other point is not included.

For example:

In an interval of the form the point is included in the set but the point is not included in the set.

Similarly, in the interval the point is included in the set but the point is not included in the set.

In order to determine the correct option which resembles with given graph form interval for each option.

Option A:

As per the statement in option A the age of the student must be at least years and not more than years that is the age of the student is either years or greater than years and less than years.

As per the above statement the interval formed is in which is included in the set and is not included which means it is a half closed or half opoen interval.

Therefore, is a correct option.

Option B:

As per the statement in option B the amount of money the babysitter can earn is between and per hour.

As per the above statement the interval formed is in which both of the end points are not included in the set which means that it is an open interval.

Therefore, is an incorrect option.

Option C:

As per the statement in option C the time required to complete a program in college cannot be less than hours and the time must be less than hours.

From the above statement it is concluded that the time required can be hours or more than hours but it has to be less than hours.

So, as per the above the statement the interval formed is .

Therefore, is a correct option.

Option D:

As per the statement in option D the age of the dogs is either years old or below years and age of the dog must be greater than   tears.

As per the above statement the interval formed is .

Therefore, the is an incorrect option.

So, are the correct options which resembles with the given graph.

(x3 + 6x2 + 2x - 6) • (x - 1)

step-by-step explanation:

polynomial long division :

3.2     polynomial long division

dividing :   x4+5x3-4x2-8x+6

                              ("dividend")

by         :     x-1     ("divisor")

dividend     x4   +   5x3   -   4x2   -   8x   +   6

- divisor   * x3     x4   -   x3            

remainder         6x3   -   4x2   -   8x   +   6

- divisor   * 6x2         6x3   -   6x2        

remainder             2x2   -   8x   +   6

- divisor   * 2x1             2x2   -   2x    

remainder               -   6x   +   6

- divisor   * -6x0               -   6x   +   6

remainder                     0

quotient :   x3+6x2+2x-6   remainder:   0

b: |12 – x| ≤ 0.25

step-by-step explanation:      

let x be the possible lengths in inches, of the ribbons jaime cut.

we have been given that jaime is cutting strips of ribbon for a project. he tries to cut each piece to be 12 inches long, but sometimes he cuts it too long or too short by as much as 0.25 inch.  

we can represent this information in an inequality as:

by the definition of absolute value function we will get,

upon combining our inequalities we will get,

therefore, the inequality   describes all the possible lengths (x), in inches, of the ribbons jaime cut.
