240 more residents have an occupation in industry than have an occupation in government. The solution has been obtained by using arithmetic operations.
It is believed that the four fundamental operations, often referred to as "arithmetic operations", can describe all real numbers. The four mathematical operations that produce the quotient, product, sum, and difference are divide, multiply, add, and subtract.
We are given a graph determining the types of occupations of the 1,200 residents of a town.
Percentage of residents having occupation in government is:
100% - 25% - 15% - 25% - 30% = 5%
Number of residents having occupation in industry is as follows:
25% of 1200 = 300
Similarly, number of residents having occupation in government is:
5% of 1200 = 60
Number of more residents that have occupation in industry than have an occupation in government is:
300 - 60 = 240
Hence, 240 more residents have an occupation in industry than have an occupation in government.

Answer:
Let's assume Pena's favorite number as "p".
According to the problem, Tonya's number is 9 more than Pena's favorite number, so Tonya's favorite number would be p + 9.
But Tonya says her favorite number is 44, so we can write:
p + 9 = 44

How many lines of symmetry are found in the following figure?
O A. no lines of symmetry
OB. 1 line of symmetry
OC. 2 lines of symmetry
D. 4 lines of symmetry
A rectangle has 2 lines of symmetry.
What is a line of symmetry?
A line of symmetry is a line that divides a shape into two mirror-image halves. When a shape is divided by a line of symmetry, each half of the shape is a reflection of the other half, and they are said to be symmetric or mirror images of each other. In other words, if you were to fold the shape along its line of symmetry, the two halves would match up perfectly. The presence or absence of lines of symmetry is an important characteristic of shapes and can be used to identify and classify them.
Calculate the line of symmetry of a rectangle -
A rectangle has two lines of symmetry: one line that runs vertically down the center of the rectangle, and another line that runs horizontally across the center of the rectangle.
To understand why a rectangle has two lines of symmetry, consider that any line that runs down the center of a rectangle will divide it into two halves that are mirror images of each other. This is true for lines that run vertically or horizontally through the center of the rectangle.
In contrast, a rectangle does not have diagonal lines of symmetry. That is, there is no line that can be drawn from one corner of the rectangle to another corner that will divide it into two mirror-image halves.
Overall, a rectangle has two lines of symmetry, and these lines are important to its geometry and properties.

By answering the above question, we may state that As a result, the coordinates graph's line has the equation y = (4/5)x + 11/5.
what are coordinates?A coordinate system in geometry is a method that employs one or more integers or coordinates to identify the precise placement of points or other geometrical objects on a manifold, such as Euclidean space. Pairs of integers called coordinates are used to locate a point or object on a two-dimensional plane. The position of a point on a 2D plane is described by two integers known as the x and y coordinates. a group of numbers that represent precise positions. Usually, there are two numbers in the figure. The front-to-back distance is represented by the first number, while the top-to-bottom distance is represented by the second number. like in (12.5), when there are 12 units below and 5 above.
In order to determine the line's equation, we must first determine the slope (m) of the line using the following formula:
m = (y2 - y1) / (x2 - x1) (x2 - x1)
where the coordinates of the two sites the line travels through are (x1, y1) and (x2, y2), respectively.
In place of the values we hold:
m = (7 - 3) / (6 - 1) (6 - 1)
m = 4 / 5
Now that we have the slope, we can solve the equation of a line using the point-slope form, which is:
y - y1 = m(x - x1) (x - x1)
where one of the locations the line travels through is (x1, y1).
y - 3 = (4/5)(x - 1) (x - 1)
y = (4/5)x - 4/5 + 3 y = (4/5)x + 11/5 is equal to y - 3 = (4/5)x - 4/5.
As a result, the graph's line has the equation y = (4/5)x + 11/5.

What is the vertical asymptote and horizontal asymptote pic attached below
The required horizontal and vertical asymptote is x = 2, -2, and y = 1/4.
How to find Asymptotes?To find the vertical asymptotes of the given rational function, we need to look for values of x that make the denominator zero, since division by zero is undefined.
The denominator of the function is 4(x-2)(x+2), so the vertical asymptotes occur at x = 2 and x = -2. Therefore, the vertical asymptotes are:
x = 2, -2
To find the horizontal asymptote, we can use the fact that as x goes to positive or negative infinity, the function approaches the ratio of the leading coefficients of the numerator and denominator.
In this case, the leading term in the numerator is x² and the leading term in the denominator is 4x². Therefore, as x approaches positive or negative infinity, the function approaches:
y = (x² / 4x²) = 1/4
So, the horizontal asymptote is:

The solutions for θ between 0 and 2π are:
θ = π/4, 3π/4, 5π/4, 7π/4.
What is trigonometry?Trigonometry is the branch of mathematics which set up a relationship between the sides and angles of right-angle triangles.
Starting with the equation:
√2sinθ + 1 = 0
Subtracting 1 from both sides, we get:
√2sinθ = -1
Squaring both sides, we get:
2sin²θ = 1
Dividing both sides by 2, we get:
sin²θ = 1/2
Taking the square root of both sides, we get:
sinθ = ± √2/2
Using the unit circle, we know that sinθ = √2/2 at π/4 and 3π/4, and sinθ = -√2/2 at 5π/4 and 7π/4.
Therefore, we have:
sinθ = √2/2 at θ = π/4 + 2πn, 3π/4 + 2πn
sinθ = -√2/2 at θ = 5π/4 + 2πn, 7π/4 + 2πn

Therefore , the solution of the given problem of equation comes out to be the 2 * √6 is the positive value of the square root of the sum of the roots.
How do equations work?Mathematical formulas frequently use the same variable letter to try to impose uniformity between two claims. Many academic numbers are shown to be equal using mathematical expression, also known as assertions. The normalise divides 12 and b + 6 into two parts using the result y + 6 = 12 as an illustration. It is possible to determine the connection between each sign component and the number of lines. The significance of a symbol usually contradicts itself.
Here,
By modifying the equation y2 + 24 = -11y, we can first convert it to standard quadratic form:
=> y^2 + 11y + 24 = 0
Using the quadratic formula, we can now determine the quadratic's roots:
=> y = (-11 ± √11^2 - 4(1)(24)))/(2(1))
=> ( -11 ± √(121 - 96))/2
=> (-11 ± √(25))/2
Thus, y = -8 and y = -3 are the solutions.
What the roots produce is:
(-8) * (-3) = 24
Additionally, the product's square root's positive number is:
=> √(24) = 2 * √(6)
In light of this, 2 * √6 is the positive value of the square root of the sum of the roots.

The number of trout in a stocked lake is given by the
equation T = 1800 (1.15)n where n is the number of months since the start of the trout season.
a. How many trout will there be in 2.5 months?
b. How many trout were there 2 months before the season opened?
a. To find the number of trout in 2.5 months, we can substitute n = 2.5 into the given equation:
T = 1800 (1.15)^n
T = 1800 (1.15)^2.5
T ≈ 2708.67
Therefore, there will be approximately 2,709 trout in the lake after 2.5 months.
b. To find the number of trout 2 months before the season opened, we need to use a negative value of n that represents the time before the start of the trout season. If we assume that the start of the season is month 0, then 2 months before the start of the season would be month -2. Thus, we can substitute n = -2 into the given equation:
T = 1800 (1.15)^n
T = 1800 (1.15)^(-2)
T ≈ 980.92
Therefore, there were approximately 981 trout in the lake 2 months before the start of the trout season.
