Answer:
![A) t^4-1\\B)-2t^2+3t+4\\C)4t-7](https://tex.z-dn.net/?f=A%29%20t%5E4-1%5C%5CB%29-2t%5E2%2B3t%2B4%5C%5CC%294t-7)
Step-by-step explanation:
When a polynomial is in standard form, it means that the terms are ordered from highest exponent to lowest exponent.
In the given options, A,B and C are ordered from the highest to the lowest and thus are in standard form.
The correct options are A,B and C.
Answer:
319,770 different task force groups might possibly be formed
Step-by-step explanation:
The order in which the members of the task force are chosen is not important, which means that the combinations formula is used to solve this question.
Combinations formula:
is the number of different combinations of x objects from a set of n elements, given by the following formula.
![C_{n,x} = \frac{n!}{x!(n-x)!}](https://tex.z-dn.net/?f=C_%7Bn%2Cx%7D%20%3D%20%5Cfrac%7Bn%21%7D%7Bx%21%28n-x%29%21%7D)
In this question:
Groups of 8 from a set of 22. So
![C_{22,8} = \frac{22!}{8!(22-8)!} = 319770](https://tex.z-dn.net/?f=C_%7B22%2C8%7D%20%3D%20%5Cfrac%7B22%21%7D%7B8%21%2822-8%29%21%7D%20%3D%20319770)
319,770 different task force groups might possibly be formed
The correct answers are
1) 1
2) 1/4

Let x represent the # of units produced and sold.
Then
Revenue = Costs
($40)x = $72000 + ($32)x
Solving for x: $8x = $72000. Thus, x = 9000.
Have to make and sell 9000 units to break even here.
