A is the answer. i hope this helps!
The required components of a <em>database function </em>in the computer science and programming includes:
- D in front of the command
- Range
- Field
- Criteria
According to the given question, we are asked to state the required components of a<em> database function </em>and how this is essential for the database to function properly.
<em />
As a result of this, we can see that the required components of the database function include the =, the range, field, criteria and the D in front of the command.

Answer:
The correct answer for option (a) is 28.29% and for option (B) is 2.65%.
Explanation:
According to the scenario, the given data are as follows:
Initial price = $117
Ending price = $147
Dividend = $3.10
(a) We can calculate the Total return percentage by using following formula:
Total return percentage = ( Ending Price - Initial Price + Dividend) ÷ Initial Price
By putting the value, we get
Total return percentage = ( $147 - $117 + $3.10) ÷ ( $117)
= 28.29% (approx).
(b). we can calculate the dividend yield by using following formula:
Dividend Yield = Dividend ÷ Initial Price
By putting the value, we get
Dividend Yield = $3.10 ÷ $117
= 2.65%
Answer:
D: Geographic segmentation
Explanation:
Geographic segmentation is defined as the marketing strategy that primarily aims to target the distinct choice preferences of the customers across a specific region or area. DeConinck Co. is employing this strategy to understand the consumer needs and cater to the different types of demands of their customers residing across the region by producing and marketing products accordingly.
Answer:
They should operate Mine 1 for 1 hour and Mine 2 for 3 hours to meet the contractual obligations and minimize cost.
Explanation:
The formulation of the linear programming is:
Objective function:
Restrictions:
- High-grade ore: 
- Medium-grade ore: 
- Low-grade ore: 
- No negative hours: 
We start graphing the restrictions in a M1-M2 plane.
In the figure attached, we have the feasible region, where all the restrictions are validated, and the four points of intersection of 2 restrictions.
In one of this four points lies the minimum cost.
Graphically, we can graph the cost function over this feasible region, with different cost levels. When the line cost intersects one of the four points with the lowest level of cost, this is the optimum combination.
(NOTE: it is best to start with a low guessing of the cost and going up until it reaches one point in the feasible region).
The solution is for the point (M1=1, M2=3), with a cost of C=$680.
The cost function graph is attached.
