As the angle ∠c in a triangle increases, the length of the middle section on line p decreases.
Conversely, as the angle ∠c decreases, the length of the middle section on line p increases. This is because the middle section on line p is a portion of the altitude of the triangle, which is the perpendicular segment from the vertex of the angle to the opposite side. As the angle ∠c increases, the altitude of the triangle gets shorter, resulting in a shorter middle section on line p. Similarly, as the angle ∠c decreases, the altitude of the triangle gets longer, resulting in a longer middle section on line p. Examples of triangles can include equilateral, isosceles, scalene, acute, right, and obtuse triangles, among others.

A square has an area of 585.64m2. Work out the perimeter of the square.
Answer:
perimeter = 96.8 m
Step-by-step explanation:
the sides of a square are congruent , then perimeter (P) is calculated as
P = 4s ( s is the side length )
the area (A ) of a square is calculated as
A = s²
given A = 585.64 , then
s² = 585.64 ( take square root of both sides )
s = [tex]\sqrt{585.64}[/tex] = 24.2
Then
P = 4 × 24.2 = 96.8 m
Answer:
= 96.8 m
Step-by-step explanation:
Area of a square = side²
Perimter of a square = 4*side
Then:
585.64 = side²
√585,64 = √side²
it is a geometric figure, therefore, only the positive value will be obtained
24.2m = side
Perimeter = 4*side
Perimeter = 4*24.2

What is the graph of the functions?Graphs of nonlinear functions are graphs of functions that do not have a constant rate of change or a linear relationship between the input and output values. Nonlinear functions include quadratic, exponential, logarithmic, trigonometric, and many other types of functions.
The shape of the graph of a nonlinear function can vary greatly depending on the specific type of function. For example:
The graph of a quadratic function (y = ax^2 + bx + c) is a parabola, which is a symmetric U-shaped curve.
The graph of an exponential function (y = a^x) is a curve that increases or decreases rapidly, depending on whether the base a is greater than or less than 1.
The graph of a logarithmic function (y = log_a(x)) is a curve that approaches a vertical asymptote as x approaches zero.
The graph of a trigonometric function (y = sin(x) or y = cos(x)) is a periodic wave that oscillates between a maximum and minimum value.
Nonlinear functions can exhibit complex and interesting behaviors, such as multiple intercepts, asymptotes, and singularities. The graphs of these functions can be used to model a wide range of real-world phenomena, such as population growth, radioactive decay, and the motion of objects under the influence of gravity.

use substitution to solve the system p=d+3, p+2d=10.50
We are given the system of equations:
p = d + 3 ----(1)
p + 2d = 10.50 ----(2)
We can use substitution to solve for the variables. From equation (1), we can see that p = d + 3. We can substitute this expression for p in equation (2) to get:
(d + 3) + 2d = 10.50
Simplifying this equation, we get:
3d + 3 = 10.50
Subtracting 3 from both sides, we get:
3d = 7.50
Dividing both sides by 3, we get:
d = 2.50
Now that we know the value of d, we can substitute this back into equation (1) to solve for p:
p = d + 3
p = 2.50 + 3
p = 5.50
Therefore, the solution to the system is p = 5.50 and d = 2.50.
to determine whether an obtained f-value is statistically significant, it must be compared to a critical f-value. what two pieces of information are needed to determine the critical f-value?
The two pieces of information which are needed to determine the critical f-value are "degrees of freedom" and "alpha level".
The critical f-value is defined as the threshold or cutoff value used to determine whether an obtained F-value is statistically significant or not.
To determine the critical f-value, we need two pieces of information:
(i) The degrees-of-freedom for numerator and denominator of the F-distribution.
These are denoted as df₁ and df₂, respectively. The degrees of freedom depend on the sample sizes and the number of groups being compared.

Super entrepreneur Freddie Fandango is peddling a new brand of high-tech tennis shoes that make different kinds of sounds each time the wearer's foot hits the ground.(so far, the two most popular sounds are "water puddle" and 'fingernails on chalkboard.") If Freddie brings in an $80 profit from every pair of shoes he sells and his expenses are $100,000, how many pairs must he sell if he wants to earn a profit of $69,840?
Using division, we can find that he must sell 2123 pairs to get a profit of $69840.
Define division?One of the four fundamental operations in mathematics is division, along with addition, subtraction, and multiplication. The splitting of a large group into smaller groups so that each group contains an equal number of items is a straightforward definition of division. It is a mathematical process used for equitable grouping and distribution.
Here,
Profit by selling one pair of shoes = $80.
Now, expenses = $100,000
Total profit he wants = $69,840.
So, total revenue to be generated = 100000 + 69840
= $169840.
Let x be the total pairs sold.
So, x = 169840/80
= 2123.
Therefore, he must sell 2123 pairs to get a profit of $69840.

Since the outputs of -5 and 1, and -1 and 7, are not equal, we can conclude that f is injective.
What is function?In mathematics, a function is a rule that assigns a unique output value to each input value in a given set. The input values are also known as the domain of the function, while the output values are known as the range. A function can be thought of as a machine that takes an input and produces an output. For example, a simple function could be doubling a number. In this case, the input is the number to be doubled, and the output is the result of doubling that number.
Here,
To determine if a function is injective, we need to check whether different inputs produce different outputs. In other words, if for any two distinct inputs x and y, f(x) is not equal to f(y), then the function is injective.
Let's examine the table of values for the function f:
× -5 -3 -1 0 3 5
f(×) 1 3 7 3 2 4
We can see that f(-5) = 1, f(-3) = 3, f(-1) = 7, f(0) = 3, f(3) = 2, and f(5) = 4.
Since the outputs of -5 and 1, and -1 and 7, are not equal, we can conclude that f is injective. Therefore, for this function, no two distinct inputs produce the same output.

Which would not be considered a long-term savings
goal?
A. Saving to go to a concert
B. Saving to buy a new house
O C. Saving for college
D. Saving for retirement
A
Consider concert tickets as a long-term savings objective.Therefore, the answer is A.
What is Savings or saving?Savings refers to anything that existing at any given moment, a stock variable, whereas saving refers to an action occurring over period, a flow variable. Even seasoned economists and financial experts frequently refer to "saving" for "savings" due to the widespread misunderstanding of this distinction.\
Saving for a concert is not a long-term savings goal because it is a short-term financial goal. Long-term savings goals typically involve saving money for events or expenses that will occur several years or even decades in the future, such as college, a down payment on a house, or retirement. Saving for a concert is unlikely to take more than a few months or a year, so it is not a long-term goal.

a figure has a height of 25 inches. it was photocopied at a scale of 40%. what is the new height of the new figure?
Answer:
10 inches
Step-by-step explanation:
If the original figure has a height of 25 inches and it was photocopied at a scale of 40%, we can find the new height of the figure by multiplying the original height by the scale factor:
new height = 25 inches x 0.4
new height = 10 inches
Therefore, the new height of the figure is 10 inches.
Answer:
Wassup
Step-by-step explanation:
By multiplying the initial height by the scale factor, which is 40% or 0.4 in decimal notation, the new height of the image can be calculated.
New height: 25 inches times 0.4 to equal 10 inches.
The figure's revised height is 10 inches as a result.
Constant percent rate of change in the equation f(x)=2(3)^x
The constant percent rate of change in the exponential function [tex]f(x) = 2(3)^x[/tex] is 200%, indicating a doubling of the output value for each unit increase in the input value.
The equation [tex]f(x) = 2(3)^x[/tex] represents an exponential function. Exponential functions have a constant percent rate of change, which means that the percent change between any two points on the graph of the function is the same.
In this case, we can find the percent rate of change by calculating the ratio of the output values for any two input values that differ by 1. For example, if we compare the output value when x=1 to the output value when x=0, we get:
[tex]f(1) = 2(3)^1 = 6[/tex]
[tex]f(0) = 2(3)^0 = 2[/tex]
The percent change from x=0 to x=1 is:
percent change = (f(1) - f(0)) / f(0) x 100%
= (6 - 2) / 2 x 100%
= 200%
This means that the output value increased by 200% when the input value increased by 1. We can also express this as a constant percent rate of change by dividing the percent change by the change in input value:
constant percent rate of change = percent change / change in input value
= 200% / 1
= 200%
Therefore, the equation [tex]f(x) = 2(3)^x[/tex] has a constant percent rate of change of 200%.

The point (1,6) is on the graph of y=f(x). What would the new co-ordinates be for the function g(x)=2f(1/3(x-1)) +5?
The new coordinates for the function g(x) at the point (1,6) are (1,5).
What is coordinates ?
Coordinates are a set of values that specify the position of a point or an object in space. They are used to locate points in a plane or in three-dimensional space. In the plane, a point can be located using two coordinates, called the x-coordinate and the y-coordinate. In three-dimensional space, a point can be located using three coordinates, called the x-coordinate, y-coordinate, and z-coordinate.
The coordinates of a point are typically written as an ordered pair (x, y) in the plane, or as an ordered triplet (x, y, z) in three-dimensional space. The x-coordinate represents the position of the point along the horizontal axis, the y-coordinate represents the position of the point along the vertical axis, and the z-coordinate represents the position of the point along the third axis, which is usually perpendicular to the x- and y-axes.
To find the new coordinates for the function g(x) given that the point (1,6) is on the graph of y = f(x), we can substitute x = 1 and y = 6 into the equation for g(x) and simplify:
g(x) = 2f(1/3(x-1)) + 5
g(1) = 2f(1/3(1-1)) + 5
g(1) = 2f(0) + 5
g(1) = 2f(0) + 5(1)
g(1) = 2f(0) + 5
Since the point (1,6) is on the graph of y = f(x), we know that f(1) = 6. To find f(0), we can use the fact that the function passes through the origin (0,0) because:
g(1) = 2f(0) + 5
g(0) = 2f(-1/3) + 5
Since the point (1,6) is on the graph of y = f(x), we can use it to find the value of f(1/3) as follows:
(1,6) is on the graph of y = f(x)
so f(1) = 6
and 1/3(1-1) = 0
This means that the point (1/3, f(1/3)) is on the graph of y = f(x). Therefore, we can use the transformation in g(x) to find the new y-coordinate for g(1) as follows:
g(1) = 2f(1/3(1-1)) + 5
g(1) = 2f(0) + 5
g(1) = 2(0) + 5
g(1) = 5
Therefore, the new coordinates for the function g(x) at the point (1,6) are (1,5).

The new number that was added to the set is 74 by using mean formula for some numbers.
Let's begin by determining the mean of a set of numbers using the following formula:
average = (sum of numbers) / (number of numbers)
We can write: since we know that the mean of 21 numbers is 30.
/ 21 = 30 = (sum of 21 numbers)
Multiply LHS and RHS by woth 10:
sum of 21 digits equals 630
The new mean will now be determined by adding a new number to the set. Let's call the new number x since we don't yet know its value. We can write: 32 = (sum of 21 numbers + x) / 22 since we also know the new mean is 32.
The result of adding the two sides together is: total of the 21 numbers plus x = 704
We may change the equation to read 630 + x = 704 as we already know the sum of the original 21 values is 630.
630 is subtracted from both sides, giving us:
x = 74
74 is the new number that was so added to the collection.

(a) what is the value of the standard error of the mean? (round your answer to the nearest whole number.) $ (b) what is the probability that the sample mean will be more than $27,175? (c) what is the probability that the sample mean will be within $1,000 of the population mean? (round your answer to four decimal places.) (d) what is the probability that the sample mean will be within $1,000 of the population mean if the sample size were increased to 100? (round your answer to four decimal places.)
(a) The standard error of the mean is 129. (b) The probability that the sample mean will be more than $27,175 is 0.50 (c) The probability that the sample mean will be within $1,000 of the population mean is 0.955. (d) The probability that the sample mean will be within $1,000 of the population mean if the sample size were increased to 100 is 0.999.
(a) The standard error of the mean is the square root of the population standard deviation divided by the sample size, which in this case is 7,400/57 = 129.12. The value of the standard error of the mean is therefore 129 (rounded to the nearest whole number).
(b) To find the probability that the sample mean will be more than $27,175, you can use the Z-score formula. The Z-score formula is (sample mean - population mean)/standard error of the mean. Therefore, the Z-score would be (27175-27175)/129 = 0. The probability that the sample mean will be more than $27,175 is 50%, since the probability of any Z-score of 0 is 0.50.
(c) To find the probability that the sample mean will be within $1,000 of the population mean, you can use the Z-score formula again. The Z-score formula is (sample mean - population mean)/standard error of the mean. Therefore, the Z-score would be (27175-27175±1000)/129 = ±7.8. The probability that the sample mean will be within $1,000 of the population mean is 95.5%, since the probability of any Z-score of ±7.8 is 0.955.
(d) To find the probability that the sample mean will be within $1,000 of the population mean if the sample size were increased to 100, you can use the Z-score formula again. The Z-score formula is (sample mean - population mean)/standard error of the mean. Therefore, the Z-score would be (27175-27175±1000)/74 = ±13.5. The probability that the sample mean will be within $1,000 of the population mean is 99.9%, since the probability of any Z-score of ±13.5 is 0.999.

The length of a rectangle is 2 in longer than its width. If the perimeter of the rectangle is 36 in, find its area. (please hurry)
Answer:
length = 10 in
width = 8 in
Step-by-step explanation:
Perimeter of a rectangle = 2(length + width)
Then:
36 = 2(h + w) Eq. 1
h = 2 + w Eq. 2
h = length
w = width
From Eq. 1
36/2 = h + w
18 = h + w Eq. 3
Replacing Eq. 2 in Eq. 3
18 = (2+w) + w
18 = 2 + 2w
18 - 2 = 2w
16 = 2w
16/2 = w
w = 8
From Eq. 2
h = 2 + w
h = 2 + 8
h = 10
Check:
from Eq. 1:
36 = 2(h + w)
36 = 2(10 + 8)

What is mean?The mean is a measure of central tendency that represents the average value of a set of numbers. There are different types of means, including the arithmetic mean , the geometric mean , and the harmonic mean.
What is spread of a data?The spread of data refers to the variability or dispersion of a set of values. It provides information about how spread out or clustered the data is. A set of data can have a high or low spread, depending on the range of values and how they are distributed.
In the given question,
The spread of a data set refers to how much the individual data points in the set vary from each other. There are several measures of spread that are commonly used, including the range, variance, and standard deviation.
To find the spread of the data set {4, 2, 6, 10, 8, 0}, we can calculate the range, which is the difference between the maximum and minimum values in the set. The maximum value in the set is 10, and the minimum value is 0, so the range is:
Range = maximum value - minimum value = 10 - 0 = 10
Therefore, the spread of the data set is 10.
