If G is a 3 x 4 matrix and His a 4x 3 matrix, what is the dimension of GH?
Neko [114]

Answer:

3x3

Step-by-step explanation:

G is a 3 x 4 matrix and His a 4x 3 matrix

In multiplication of matrix a particular formula is used

If G = MN and H = NM then GH = MM

So G= 3x4 and H = 4x3

Then GH = 3x3

The above rule is a rule that binds matrix multiplication and allows for an easier calculations and also helps check the possibility of the multiplication.

As for the above, the multiplication is possible an the result of the multiplication will give us a 3x3 matrix

x = 7


General Formulas and Concepts:
Order of Operations: BPEMDAS


Step-by-Step Explanation:
Step 1: Define
5(x - 3) = 2(x + 3)

Step 2: Solve for x

Describe how to draw the geometric mean in a right triangle
CaHeK987 [17]
Answer: The height of the altitude from the hypotenuse to the vertex of the right angle is the geometric mean of the two segments formed on the hypotenuse.

The geometric mean of two numbers is the square root of the product of the numbers.

When you draw your altitude, you will divide the hypotenuse into 2 segments. The geometric mean of those two lengthsis also the height of the altitude.
