Find the product of the elements on the main

Answer:

The solution is d₁ = 24

The product of the elements on the main diagonal of the matrix is 24

What is multiplication of matrices?

The product of two matrices A and B is defined if the number of columns of A is equal to the number of rows of B. The first matrix must have the same number of columns as the second matrix has rows. The number of rows of the resulting matrix equals the number of rows of the first matrix, and the number of columns of the resulting matrix equals the number of columns of the second matrix

Given data ,

Let the matrix be represented as A

Now , the value of A is

[tex]A = \left[\begin{array}{ccc}3 &2 \\ 5 &8 \\\end{array}\right][/tex]

Now , on simplifying the matrix A

The main diagonal of the matrix is having the elements ( a₁₁ ) and ( a₂₂ )

So , the product of the elements in the main diagonal is

a₁₁ = 3

a₂₂ = 8

And , the equation will be

d₁ = ( a₁₁ ) x ( a₂₂ )

Substituting the values in the equation , we get

d₁ = 3 x 8

d₁ = 24

Therefore , the value of d₁ is 24

Hence , the product of the diagonal elements of matrix is 24

B. a square must have 4 right angles, but a rhombus may or not have 4 right angles.

Answer:

B

Step-by-step explanation:

The main difference between a square and a rhombus is a square must have 4 right angles, but a rhombus may or may not have 4 right angles. All the angles of a square have to be 90 degrees. All right angles are 90 degrees. All squares are rhombuses, but not all rhombuses are squares. There are occasions when a rhombus has 4 right angles.

The volume of a cone is given by v=13πr2h. If a cone has volume 3π, what is the height of the cone when the radius is 12?

Answers

Answer:

16units

Step-by-step explanation:

Given data

The expression for the volume of a cone is given as

v=1/3πr^2h

v= 3π

r= 12

h=???

Substitute

3π= 1/3*π*12^2*h

3= 1/3*144*h

3= 144h/3

cross multiply

3*3= 144h

9= 144h

h= 144/9

h=16 units

The required measures of the circle are:

mDF = 75, m∠FBE 105, mFC=60
m∠CBE = 45, mDAC = 225. m∠ABE=135

m∠ABF=120

What are the sections of the circle?

A section of a circle is a region enclosed by a chord and an arc of the circle. It is also called a circular sector. A circular sector is defined by its central angle, which is the angle between the two radii that form the sector, and its radius, which is the distance from the center of the circle to the endpoints of the sector.

Here,
A circle is shown,

mDF = 75  [shown in the image]

m∠FBE = 60 + ∠CBE

m∠FBE = 60 + ∠ABD     [∠ABD=∠CBE]

m∠FBE = 60 + 45             [∠ABD = 180 - 75-60]

m∠FBE = 105,

Similarly,

mFC=60, m∠CBE = 45, mDAC = 225, m∠ABE=135, and m∠ABF=120

What is the area of the following figure?

Answers

Answer:

Area = 136

Step-by-step explanation:

Rectangle on the bottom

Length = 16

Width = 7

Area = L * W

Area = 16 * 7

Area = 112

Triangle on Top

Height = 13 - 7 = 6

Length = 16 - 8 = 8

In a right triangle the area = the product of the 2 shortest sides divided by 2

Area = 1/2 * Length * Height

Area = 1/2 * 8 * 6

Area = 1/2 48

Area = 24
