For the first problem, the answer is choice A) 8
The notation "a32", with the "32" as a subscript, means "the address of row 3, column 2". The value that is in row 3, column 2 is the value 8. The row number is always listed first when it comes to addressing in matrices.
---------------------------------------------------------------------------------------
For the second problem, we can only add together matrix A and matrix D, as they are the same size (2x2 matrices). We cannot add any other pairs together because of the size mismatch. In order to add any two matrices, they must have the same number of rows and the same number of columns.
Another example would be adding two 3x1 matrices together. They both have 3 rows and 1 column.
Answer:
39.30 
Step-by-step explanation:
The area of the top surface of the wedge is the same as the area of a sector.
Area of a sector = (θ/
)

where: θ is the central angle, and r is the radius.
Given that: central angle =
, radius = 10 centimetre.
Area of the top surface = Area of a sector = (θ/
)

=

x 100
= 39.2857
= 39.30 
The area of the top surface of the wedge is 39.30

The point of intersection is the point where two or more functions meet.
The graphs of the hyperbola and ellipse have 0 point of intersection
The given parameters are:


To determine the points of intersection, we simply equate both equations.
So, we have:

Cancel out the common terms

Collect like terms


Divide through by 5

Divide through by y

<em>The system of equation does not give room to calculate the x-coordinate at the x-axis.</em>
<em />
Hence, the graphs of the hyperbola and ellipse have <em>0 point of intersection</em>
