The following represent matrices and the dimension of each is also stated below. A is a matrix of size 4X2 B is a matrix of size 3X5 C is a matrix of size 7X2 D is a matrix of size 5X4 E is a matrix of size 5X3
The questions does not look complete, we can complete the question thus
The following represent matrices and the dimension of each is also stated below. A is a matrix of size 4X2 B is a matrix of size 3X5 C is a matrix of size 7X2 D is a matrix of size 5X4 E is a matrix of size 5X3.
Which of the following matrices products are defined?
EB is defined
BE is defined
BD is defined
and DA is defined
To know that the product of two matrices are defined, the column of the first matrix must be the same as the row of the second matrix.
For example; for EB we have 5 columns for E and 5 rows for B. After this product is done it produces a matrix with dimension 3 x 3, which means 3 by 3 (3 rows by 3 columns)
A scam drawing of a rectangle park is 5 inches wide and 7 inches
where is the question
If you are asking for area, the answer is 35inches squared.
Area is length times width, so multiply 5 and 7,
Which gives you 35 inches squared
A regular octagon can be concave.
True or False? Please explain.
a regular polygon has all equal angles, interior and exterior, as well as all equal sides.
Check the picture below.
the one on the left is a regular octagon, as well as a convex one.
the one on the right is also an octagon, but is concave, the issue is that, though all sides remain equal, the angles do not, and so is not a regular octagon.
What is the quotient of 28 divided by 7 increased by 4
The quotient after increased by 4 is 8.
To calculate the quotient of 28 divided by 7, we perform the division and get:
28 ÷ 7
= (7 x 4)/ 7
Next, we are asked to increase this quotient by 4. Adding 4 to the quotient:
= 4 + 4
Therefore, the quotient after increased by 4 is 8.
