what is the determinant of the identity matrix I?

Answers

Answer 1

Answer:

Explanation:

The ith column of an identity matrix is the unit vector ei (the vector whose ith entry is 1 and 0 elsewhere) It follows that the determinant of the identity matrix is 1, and the trace is n. When the identity matrix is the product of two square matrices, the two matrices are said to be the inverse of each other.

The effect when one part of a system changes C. The open-loop system becomes a closed-loop system.

Systemic change is generally understood to require adjustments or transformations in the policies, practices, power dynamics, social norms or mindsets that underlie the societal issue at stake. It often involves the collaboration of a diverse set of players and can take place on a local, national or global level.

How does a systemic change happen?

All systems organize individual pieces into some sort of interrelated whole. Put simply, systemic change occurs when change reaches all or most parts of a system, thus affecting the general behavior of the entire system.

Why is systems change important?

A systems-change approach is more appropriate for problems that are complex, unpredictable, and context-dependent. For example, the challenge of inadequate access to educational opportunities for children from low-income neighborhoods cannot be addressed with a straightforward, logistical fix.

In the recursive function findMatch(), the first call is findMatch(array, 0, 4, key) . What are the remaining function calls to find the character 'e'?
public class FindMatch {
public static int findMatch(char array[], int low, int high, char key) {
if (high >= low) {
int mid = low + (high - low) / 2;
if (array[mid] == key) {

if (array[mid] > key) {
return findMatch(array, low, mid, key);
}
else {

Answers

Answer:

The answer is "Option D".

Explanation:

In the given question "(array, 3, 4, key) and (array, 4, 4, key)", the element 'e' to also be searched is concentrated mostly on the right-hand side of the array since it is in the last place. This same middle value is 2 but findMatch(array, mid + 1 high, key) is labeled twice to move the center pointer to its last position, that is, so move that search item's 'e.'

b) 2 2 2 2 2
c) 2 4 8 16 32 64 End
d) 2 4 8 16 32

Answers

Answer:

The output of the program is:

2 4 8 16 32 64 End

Explanation:

See attachment for proper presentation of the program

The program uses recursion to determine its operations and outputs.

The function is defined as: myMathFunction(int a, int r, int counter)

It initially gets the following as its input from the main method

a= 1; r = 2; counter = 0

Its operation goes thus:

val = a*r; 1 * 2 = 2

Print val; Prints 2

if (counter > 4) { System.out.print("End"); } : Not true
