diagonal of matrix A:
d1 = (a11)(a22)
Answer:
24
Step-by-step explanation:
thats right
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

Geometry help please. Find m in the diagram please.
Answer:
m = 8
Step-by-step explanation:
[tex]\frac{m}{12}[/tex] = [tex]\frac{10}{5+10}[/tex]
15m = 120
m = 8
Use csc (90) = 10/m.
So, m = 10/csc(90).
m = 8.93997

[tex]\huge{\{\fbox{\tt{Questions }}\}}[/tex]
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?
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
Total Area = 112 + 24 = 136
What is the main difference between a square and a rhombus?

A rhombus has 4 right angles, and a square does not.
B.
A square must have 4 right angles, but a rhombus may or may not have 4 right angles.
C.
A square has sides that are parallel, but a rhombus does not.
D.
A rhombus is always bigger than a square.
Answer:
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.

Answer:
202m
Step-by-step explanation:
Use pythagoream theorum to find the hypotenuse. So [tex]a^{2} +b^{2} =c^{2}[/tex], where the height (40m)=a and the anchor length (198m)=b. That leaves us with [tex]40^{2} +198^{2} =c^{2}[/tex], doing the math out for that we get 40,804=[tex]c^{2}[/tex], taking the square root of 40,804 we get our answer of 202m

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?
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
Hence the heeight is 16units

If these cubes are to to be placed so that their respective faces are parallel
or perpendicular, as the case may be, to the respective orientations of the
dimensions of the box, without tilting any cubes in any directions,
then choice B) can be justified. This leaves spaces (some volume) in the box
not filled by the cubes.
How many whole number of edges of the cubes fit into 4 cm?
4 / 3 √ 2 must be rounded down to 3.
How many whole number of edges of the cubes fit into 8 cm?
8 / 3 √ 2 must be rounded down to 6.
How many whole number of edges of the cubes fit into 10 cm?
10 / 3 √ 2 must be rounded down to 7.
Then (3)(6)(7) = 126
