Answer:

c. You cannot change the name, return type, or parameters of a method defined by the interface.

Explanation:

When implementing an interface:

The return type of the implementing method should be same as the one defined in the interface.

The parameters of the implementing method should be the same as defined in the interface.

The name of the method should be the same as that defined in the interface.

So among the given options , option c is the most relevant as it captures all the above conditions.

Automated Reasoning

Explanation:

Automated reasoning is a type of Natural language understanding(NLP) in computer science that makes logical inferences based on information or data previously gathered. Automated reasoning allows computers make intelligent decisions and reason logically based on data gathered. For example, a system is based to scan online reviews and conclude on the ones that are negative reactions based on previous data.

Find the equation of a line which has 10 points the following two coordinates: (4, 0) and (3, 4)

alex41 [277]

Answer:

The equation of the line is y = -4·x + 16

10 points on the line include;

(0, 16), (1, 12), (2, 8), (3, 4), (4, 0), (5, -4), (6, -8), (7, 12), (8, -16), (9, -20), and (10, -24)

Explanation:

The given points through which the line passes are;

(4, 0) and (3, 4)

The slope, 'm', of the line is given as follows;

$Slope, \, m =\dfrac{y_{2}-y_{1}}{x_{2}-x_{1}}$

Therefore, the slope of the line is (4 - 0)/(3 - 4) = -4

In point and slope form we can get;

$\dfrac{y-0}{x-4} = -4$

The equation of the line in point and slope form is therefore;

y = -4·(x - 4) = -4·x + 16

The equation of the line in slope and intercept form is

y = -4·x + 16

10 points on the line are obtained using the equation of the line and the desired x-values input into cells on MS Excel and presented here as follows;

(0, 16), (1, 12), (2, 8), (3, 4), (4, 0), (5, -4), (6, -8), (7, 12), (8, -16), (9, -20), and (10, -24)

laiz [17]

Answer:

O(n²)

Explanation:

The worse case time complexity of insertion sort using binary search for positioning of data would be O(n²).

This is due to the fact that there are quite a number of series of swapping operations that are needed to handle each insertion.
