23 is the constant rate of change..............
Answer:
B. 8
Step-by-step explanation:
The question lacks the required diagram. Find the diagram in the attachment.
Before we can find d21, d22 and d23, we need to get the matrix D first as shown in the attached solution.
On comparison as shown in the attachment, d21 = 11, d22 = -10 and d23 = 7
Note that d21 refers to element in the second row and first column of the matrix
d22 is the element in the second row and second column of the matrix
d23 is the element in the second row and third column of the matrix
d21+d22+d23 = 11-10+7
d21+d22+d23 = 8
The second option is correct.
According to the information given above,
A = [2, 4]
B = [5, 6]
A Intersection B = [1, 7]
The element of {A N B]! are those elements which are in both set A and set B with the exception of the elements that forms the intersection between them.
Thus, for the question given above,
{A N B]! = [2, 4, 5,6].
If you divide 90 by 6 you get 15. This means the answer is 2.
