The order of the matrix is 2 x 2.
What is a matrix and what is meant by its order?
In the field of mathematics, matrices are rectangular arrangements of numerical values, symbols, or algebraic expressions, organized in rows and columns. Matrices are used in many areas of mathematics and science, as well as in engineering, physics, and computer graphics.
The term 'order' in the context of matrices refers to the dimensions of the matrix, which are determined by the number of rows and columns it contains. It is denoted by m x n, where m is the number of rows and n is the number of columns. To find the order of a matrix, we simply count the number of rows and columns. The order is usually written as a pair of numbers in the form m x n.
Determine the order of the given matrix:

If m∠ A=5x+6 and m∠ B= 7x-18 Find m∠C
Answer:
We know that the sum of the angles in a triangle is 180 degrees. Therefore, we can write:
m∠A + m∠B + m∠C = 180
Substitute the given values:
5x+6 + 7x-18 + m∠C = 180
Combine like terms:
12x-12 + m∠C = 180
Add 12 to both sides:
12x + m∠C = 192
Subtract 12x from both sides:
m∠C = 192 - 12x
Therefore, m∠C is equal to 192 minus 12 times x.

Find the derivative of the following, using differentiation from first principles. f(x) = 2x²-1/x
The required derivative of [tex]f(x) = \frac{2x^3 - 1}{x}$[/tex] is [tex]$f'(x) = 4x + \frac{1}{x^2}$[/tex].
What is differentiation?A technique for determining a function's derivative is differentiation. Mathematicians use a method called differentiation to determine a function's instantaneous rate of change based on one of its variables. The most typical illustration is velocity, which is the rate at which a distance changes in relation to time.
The function [tex]f(x) = \frac{2x^3 - 1}{x}$[/tex] can be written as [tex]f(x) = 2x^2 - \frac{1}{x}$[/tex].
The derivative of f(x) can be found using the power rule and the derivative of 1/x, which is[tex]-\frac{1}{x^2}$[/tex].
Therefore, we have:
[tex]$f'(x) = 4x + \frac{1}{x^2}$$[/tex]
So the derivative of [tex]f(x) = \frac{2x^3 - 1}{x}$[/tex] is [tex]$f'(x) = 4x + \frac{1}{x^2}$[/tex].

The customer service department of a company found that the relationship between the number of minutes a customer spends on hold when telephoning and the customer's level of satisfaction on a 10-point scale can be approximated by the equation y=10−0.1x
, where x
is the number of minutes on hold and y
is the level of satisfaction. What does 0.1 represent in the equation?
In the equation y = 10 - 0.1x, the coefficient 0.1 represents the slope of the line.
Define slopeit represents the rate of change of y with respect to x, which is the amount by which y changes for every unit increase in x.
In this case, the slope is negative (-0.1), which means that as the number of minutes on hold (x) increases by 1 unit, the level of satisfaction (y) decreases by 0.1 units.
In other words, the longer a customer spends on hold, the lower their level of satisfaction is likely to be. The slope is a key parameter in the equation and provides valuable information about the relationship between the two variables.

Suppose you are a ladybug on the “outer” surface of the Klein bottle. Describe a path on the surface of the bottle that you can travel that would get you to the “inside” where a special gentleman bug is waiting.
As a ladybug on the outer surface of the Klein bottle, there is no direct path to the inside. However, you can travel along a specific type of curve called a "cross-cap curve" to reach the inside. and using topology.
To do this, start by moving along the outer surface of the Klein bottle until you reach the point directly opposite to your starting position. Then, imagine folding the surface of the bottle in half along a line that runs through this point.
This folding will create a new surface that intersects with the original surface of the bottle along a cross-cap curve. Follow this curve until you reach the inside of the Klein bottle, where the special gentleman bug is waiting for you.
It's important to note that the Klein bottle is a non-orientable surface, which means that there is no "inside" or "outside" in the traditional sense. However, the concept of inside and outside can still be useful for navigation purposes.

blank+7/10=2 9/20
To subtract 6/7 from 2 1/4, we need to find a common denominator. The least common multiple of 7 and 4 is 28, so we can convert 2 1/4 to 9/4 and 6/7 to 24/28. Then we can subtract:
9/4 - 24/28
= 63/28 - 24/28
= 39/28
Therefore, 2 1/4 - 6/7 = 39/28.
To solve for the blank in 2 5/12 - blank = 2/3, we can start by converting 2 5/12 to an improper fraction:
2 5/12 = (2*12 + 5)/12 = 29/12
Then we can subtract 2/3 from both sides:
2 5/12 - 2/3 = blank
To subtract these fractions, we need to find a common denominator. The least common multiple of 3 and 12 is 12, so we can convert 2/3 to 8/12. Then we can subtract:
29/12 - 8/12
= 21/12
= 7/4
Therefore, the blank in 2 5/12 - blank = 2/3 is 7/4.
To subtract 5 3/8 from 7 1/12, we need to find a common denominator. The least common multiple of 8 and 12 is 24, so we can convert both mixed numbers to improper fractions:
7 1/12 = (712 + 1)/12 = 85/12
5 3/8 = (58 + 3)/8 = 43/8
Then we can subtract:
85/12 - 43/8
= 85/12 - (433)/(83)
= 85/12 - 129/24
= 5/24
Therefore, 7 1/12 - 5 3/8 = 5/24.
To solve for the blank in blank + 7/10 = 2 9/20, we can start by converting 2 9/20 to an improper fraction:
2 9/20 = (2*20 + 9)/20 = 49/20
Then we can subtract 7/10 from both sides:
blank + 7/10 - 7/10 = 49/20 - 7/10
Simplifying the right side:
49/20 - 7/10 = (492)/(202) - (74)/(104) = 98/40 - 28/40 = 70/40 = 7/4
Therefore, blank + 7/10 - 7/10 = 7/4, and solving for blank:
blank = 7/4
Therefore, the blank in blank + 7/10 = 2 9/20 is 7/4.

Assuming that a 390 foot tall giant redwood grows vertically, if I walk a certain distance from the tree and measure the angle of elevation to the top of the tree to be 39°, how far from the base of the tree am I?
Answer:
You can use trigonometry to solve this problem. The distance from the base of the tree to where you are standing forms the adjacent side of a right triangle, with the height of the tree being the opposite side and the angle of elevation being 39°.
Using the tangent function: tan(θ) = opposite/adjacent
tan(39°) = 390 / adjacent
Adjacent = 390 / tan(39°)
Adjacent ≈ 496.4 feet
So you are approximately 496.4 feet away from the base of the tree.

A tank in the shape of a hemisphere has a radius of 8 feet. If the liquid that fills the tank has a density of 98.9 pounds per cubic foot, what is the total weight of the liquid in the tank, to the nearest full pound?
Answer:
848,775 pounds
Step-by-step explanation:
The volume of a hemisphere with radius 8 feet is:
V = (2/3)πr^3 = (2/3)π(8^3) = 268.08 cubic feet
The weight of the liquid is given by:
W = V * ρ * g
where ρ is the density of the liquid and g is the acceleration due to gravity. Plugging in the values, we get:
W = 268.08 * 98.9 * 32.2 = 848,774.7 pounds
Rounding to the nearest full pound, the total weight of the liquid in the tank is 848,775 pounds.
Please helpppp it’s urgent!!! Assume you have a balance of $3000 on a credit card with an APR of 24 %, or 2 % per month. You start making monthly payments of $200, but at the same time you charge an additional $100 per month to the credit card. Assume that interest for a given month is based on the balance for the previous month. How long does it take to pay off the credit card debt? Round your numbers to the nearest cent?
It will take around 3.72 months to pay off the credit card debt.
Explain about the annual percentage rate APR?The annual rate of interest that a person must pay on a loan or receives on a bank account is known as the annual percentage rate (APR).APR is utilized for everything, including credit cards, auto loans, and mortgages.The formula for APR is:
A = P * [tex](1 + r/n)^{nt}[/tex]
In which,
A = amount after compounding.
P = balance amount
r = rate of interest.
n = number of time compounded.
Initial balance: $30,000.
Payments per month = $200.
Expenses = $100
Balance amount = 30,000 - 12 *(200 - 100)
Balance amount = $28800
So, time taken for paying off credit card debt.
30,000 = 28800 [tex](1 + 0.24/1)^{1*t}[/tex]
[tex](1.24)^{t}[/tex] = 30,000 / 28800
[tex](1.24)^{t}[/tex] = 1.04
Solve by using logarithmic function.
t = ln (1.04) / 1.24
t = 0.31 year
t = 3.72 months
Thus, it will take around 3.72 months to pay off the credit card debt.

Question 8 Suppose the graph of rectangle ABCD shows the scale drawing for a safety fence that Kenny is setting up around a construction area. Each unit on the graph represents 25 feet. After studying the scale drawing, Kenny decides to build a fence that encloses a larger area. If Kenny dilates rectangle ABCD by a scale factor of 2.5, and fencing costs $5.25 per foot, how much will he spend on fencing?
Kenny will spend $4,593.75 on fencing the dilated rectangle.
What is rectangle ?
A rectangle is a quadrilateral with four right angles (90-degree angles) and opposite sides of equal length. It is a type of parallelogram in which both pairs of opposite sides are parallel and congruent (of equal length). The opposite sides of a rectangle are also perpendicular (form a right angle) to each other. The area of a rectangle is equal to the product of its length and width, while its perimeter is equal to the sum of the lengths of all its sides. Rectangles are commonly used in geometry, architecture, engineering, and many other fields.
According to the question:
Since each unit on the graph represents 25 feet, the dimensions of the original rectangle ABCD are:
AB = 4 units, which represents 4 x 25 = 100 feet
BC = 3 units, which represents 3 x 25 = 75 feet
Therefore, the perimeter of ABCD is 2(AB + BC) = 2(100 + 75) = 350 feet.
When dilating by a scale factor of 2.5, each dimension of ABCD will be multiplied by 2.5. Therefore, the dimensions of the dilated rectangle A'B'C'D' are:
A'B' = AB x 2.5 = 100 x 2.5 = 250 feet
B'C' = BC x 2.5 = 75 x 2.5 = 187.5 feet
The perimeter of A'B'C'D' is 2(A'B' + B'C') = 2(250 + 187.5) = 875 feet.
Therefore, Kenny will need to fence a perimeter of 875 feet. At a cost of $5.25 per foot, the total cost of fencing will be:
875 feet x $5.25/foot = $4,593.75
Therefore, Kenny will spend $4,593.75 on fencing the dilated rectangle.

Winston's economic profit based on the forgone salary of $60,000, and the revenue of $150,000 is $78,000. The correct option is therefore;
$78,000
What is an economic profit?An economic profit is a profit that accounts for both the explicit and implicit costs of a business. The economic profit is obtained from the difference between the total revenue and the costs including the opportunity costs.
The annual salary of Winston as an accountant = $60,000
The amount Winston's financial asset generates = $4,000 per year
The cost of running the business = $8,000
The amount Winston earns as revenue = $150,000
Therefore;
Winston's opportunity cost which is the forgone alternative, is the amount he earns as an accountant = $60,000
The interest of $4,000, earned from the financial asset = The cost of using the financial asset for the business
The cost of running the business = $8,000
The total cost = Opportunity cost + Cost of making use of the financial asset + The business running cost
The total cost = $60,000 + $4,000 + $8,000 = $72,000
The economic profit = The total revenue - The total cost

The exponential function system that intersects as x = 1, is [tex]y = 3(1)^x[/tex] and [tex]y = \frac{6}{8} \times (4)^x[/tex].
What is an exponential function?The formula for an exponential function is [tex]f(x) = a^x[/tex], where x is a variable and a is a constant that serves as the function's base and must be bigger than 0.
The d Here are two different exponential functions of the required form that intersect at x = 1 -
[tex]y = 3(1)^x[/tex]
[tex]y = \frac{6}{8} \times (4)^x[/tex]
In the first equation, a = 3, and b = 2.
Plugging in x = 1, we get -
[tex]y = 3(1)^1[/tex]
y = 3 × 1
y = 3
So the point of intersection of this equation with the x-axis is (1, 3).
In the second equation, a = 6/8 , and b = 4.
Plugging in x = 1, we get -
[tex]y = \frac{6}{8} \times (4)^1[/tex]
y = 3/4 × 4
y = 3
So the point of intersection of this equation with the x-axis is also (1, 3).
So, both of these equations intersect at x = 1 and are of the form [tex]y = a \times b^x[/tex].
Therefore, the equations are [tex]y = 3(1)^x[/tex] and [tex]y = \frac{6}{8} \times (4)^x[/tex].

6x^2 + 60x + c what is c so to make it a perfect square trinomial
The calclulated value of c to make a perfect square trinomial from 6x^2 + 60x + c is 150
Calculating the value of c to make a perfect square trinomialTo make a quadratic trinomial a perfect square trinomial, we need to add a constant term that is equal to half of the coefficient of the x-term, squared.
In other words, we need to find a value of c such that:
6x^2 + 60x + c = Perfect square trinomial
Divide through by 6
So, we have
x^2 + 10x + c/6 = Perfect square trinomial
Take the coefficient of x
k = 10
Divide by 2
So, we have
k/2 = 5
Square both sides
(k/2)^2 = 25
This means that
c/6 = 25
So, we have
c = 150
Therefore, to make the trinomial 6x^2 + 60x + c a perfect square trinomial, we need to choose c = 150.

C. A = -5²
d.
A = 2-m-10
The area should the base of the new container must have option D that is, A = 2m-10.
What is area?In mathematics, area is a measurement of the size of a two-dimensional surface or shape, usually measured in square units such as square meters, square centimeters, or square feet. It is the amount of space inside the boundary of a flat object or shape.
Here,
To calculate the area of the base of the new container, we need to find the radius of the container first. Since the diameter is given as 10 cm, the radius would be half of that, which is 5 cm. The formula for the area of a circle is A = πr², where A is the area and r is the radius. So, substituting the values, we get:
A = π(5 cm)²
A = π(25 cm²)
A = 25π cm²
However, the answer choices are not in this format. To simplify the answer, we can use the value of π as approximately 3.14 (rounded to two decimal places). So, the area of the base would be:
A = 25π cm²
A ≈ 25(3.14) cm²
A ≈ 78.5 cm²
Now, we need to choose the answer option that represents this area in terms of variables. The only option that matches is:
d. A = 2m-10

Find the midpoint of AB if A located at (1, 4) and B is located at (3, -6).
Answer:
The midpoint of a line segment AB with endpoints A(x1, y1) and B(x2, y2) is given by the coordinates:
[(x1 + x2) / 2, (y1 + y2) / 2]
In this case, A is located at (1, 4) and B is located at (3, -6). So the midpoint M of AB is:
[(1 + 3) / 2, (4 + (-6)) / 2]
= [2, -1]
Therefore, the midpoint of AB is at the point (2, -1).
The coordinates of the midpoint of the line AB is [2, -1]
What is section formula?Section formula is used to find the ratio in which a line segment is divided by a point internally or externally.
It is used to find out the centroid, incenter and excenters of a triangle. In physics, it is used to find the center of mass of systems, equilibrium points, etc.
Given that, we need to find the midpoint of AB if A located at (1, 4) and B is located at (3, -6).
The midpoint of a line segment AB with endpoints A(x1, y1) and B(x2, y2) is given by the coordinates:
[(x1 + x2) / 2, (y1 + y2) / 2]
In this case, A is located at (1, 4) and B is located at (3, -6).
So the midpoint M of AB is:
= [(1 + 3) / 2, (4 + (-6)) / 2]
= [2, -1]
Hence, the midpoint of AB is at the point (2, -1).
