Answer:
Step-by-step explanation:
Given: 4 - 9x +21
Factorizing this expression, we have;
4 -3(3x - 7)
i. Chang's expression: 4 - 3(3x + 7)
This is not an equivalent expression, because by expansion of the bracket, the expression gives: 4 -9x -21
ii. Benjamin's expression: 4 + 3(3x + 7)
This is not an equivalent expression, because by expansion of the bracket, the expression gives: 4 +9x +21
iii. Habib's expression: 4 + 12x
This is not an equivalent expression, because the expression is not related to the given question
Comparing the three student's answers with the appropriate expression, none of the student's is an equivalent expression.
This expression that is equivalent to the given question is;
4 -3(3x - 7) = 4 -9x + 21

Answer:
1) h = -1/2t^2 +10t
2) h = -1/2(t -10)^2 +72
3) domain: [0, 20]; range: [0, 50]
Step-by-step explanation:
1.) I find it easiest to start with the vertex form when the vertex is given. The equation of the presumed parabolic path for Firework 1 is ...
h = a(t -10)^2 +50
To find the value of "a", we must use another point on the graph. (0, 0) works nicely:
0 = a(0 -10)^2 +50
-100a = 50 . . . . . . subtract 100a
a = -1/2 . . . . . . . . . divide by -100
Then the standard-form equation is ...
h = (-1/2)(t^2 -20t +100) +50
h = -1/2t^2 +10t
__
2.) The path of Firework 2 is translated upward by 22 units from that of Firework 1.
h = -1/2(t -10)^2 +72
__
3.) The horizontal extent of the graph for Firework 1 is ...
domain: 0 ≤ t ≤ 20
The vertical extent of the graph for Firework 1 is ...
range: 0 ≤ h ≤ 50

Final answer:
The Economic Entity Assumption is a key principle in accounting, enabling economic events of individual entities to be separately identified and accounted. The correct answer to the question is 'D. of every entity can be separately identified and accounted for.', which means all types of entities, such as corporations or sole proprietorships, can have their economic events independently accounted for.
Explanation:
The Economic Entity Assumption is a principle in accounting that allows us to separate and identify the economic activities of different entities. This assumption plays an integral role in the management and understanding of a business’s financial health, as it enables the financial activities of a business to be distinguished from the personal financial activities of its owners. In response to the options given, the correct answer is 'D. of every entity can be separately identified and accounted for'. This means that each economic entity's events can be clearly differentiated and accounted for independently, regardless of whether they're corporations, sole proprietorships, or any other type of business model.

Final answer:
The economic entity assumption states that the economic events of every entity can be accounted for separately. This principle is vital for accuracy and transparency in financial reporting, as it mandates the separation of business and personal financial activities.
Explanation:
The economic entity assumption is a fundamental principle in accounting. The correct answer is option D: economic events of every entity can be separately identified and accounted for. This assumption holds that the financial activities of a business entity should be kept separate from the personal financial activities of its owners or other business entities. For instance, a sole proprietor's personal expenses should not be mixed with the expenses of the business they own. This principle helps ensure the transparency and accuracy of a business's financial records. Without the economic entity assumption, accurately tracking and reporting financial information would be far more complex and confusing.

8.001 × 10^7
Step-by-step explanation:
Move the decimal so there is one non-zero digit to the left of the decimal point. The number of decimal places you move will be the exponent on the 1010. If the decimal is being moved to the right, the exponent will be negative. If the decimal is being moved to the left, the exponent will be positive.
