Correct Answer: A) Market positioning

Explanation

The correct answer is Option A: Market positioning.

Market positioning is the process of identifying and targeting a specific market segment with a unique product or service. It involves understanding the needs and preferences of the target market and creating a product or service that meets those needs better than the competition. By doing this, the organization can position itself as the go-to provider for that particular market segment.

Market integration, on the other hand, refers to the process of combining different parts of a market or industry together. It typically involves mergers, acquisitions, or partnerships between companies in order to create a more unified and efficient market.

Market orchestration is a term that is not commonly used in commerce. It may refer to the coordination and management of various marketing activities and strategies within a market.

Product differentiation is the process of distinguishing a product or service from others in the market. It involves creating unique features or attributes that set the product apart and make it more appealing to consumers.

So, in this case, when the organization studies an underserved market and creates a product or service specifically for that market, it is engaging in market positioning. This allows the organization to cater to the unique needs of the underserved market and gain a competitive advantage.

Correct Answer: B. 3.0 s

Explanation

\(F = ma \)

\(10 = 2.5a \implies a = 4 ms^{-2}\)

Since it is a retarding movement, then \(a = -4 ms^{-2}\).

\(v = u + at; v = 0 ms^{-1}, u = 12 ms^{-1}\)

\(0 = 12 + (-4t) \implies 0 = 12 - 4t\)

\(4t = 12 \implies t = 3 s\)

Explanation

a.

b. the graph above, solution to question 8b.

ci. The roots of the equation from the graph are -1.2 and 1.7.

ii. Let y = \(2x^2 - x - 4\)

\(\frac{dy}{dx}\) = 4x - 1

At critical point \(\frac{dy}{dx}\) = 0

so that 4x - 1 = 0;

x = \(\frac{1}{4}\)

Using test points:

1. we use a test point less than \(\frac{1}{4}\), e.g x = 0

\(\frac{dy}{dx}\)(0) = 4(0) - 1 = -1

at this point, y = \(2x^2 - x - 4\) is decreasing

2. we use a test point greater than \(\frac{1}{4}\) e.g x = 1

\(\frac{dy}{dx}\)(1) = 4(1) - 1 = 4 - 1 = 3.

at this point, y = \(2x^2 - x - 4\) is increasing.

so, the function y = \(2x^2 - x - 4\) increases as x increases when x is greater than \(\frac{1}{4}\)

Therefore, the value of x for which y increases are x is greater than \(\frac{1}{4}\)

iii. The minimum point of y = -4.1.

Correct Answer: B. is

Explanation

The correct option is B. is.

Expressions of time, money, distance, and weight (such as *four weeks*, *ten dollars*, *five miles*) are treated as a single unit or collective quantity, and therefore take a singular verb.

Thus, the sentence reads:

*Four weeks is enough for the police to conclude their investigation?*

Correct Answer: C. in the root nodules

Correct Answer: D. Hausa

Correct Answer: D. rhetorical question

Correct Answer: D. dignity of labour.
