Answer:
a. An absolute value inequality that represents the possible actual temperature t is:
|t - 72| < 2
b. To find the range of possible actual temperatures, we can solve the inequality:
|t - 72| < 2
We can split this into two separate inequalities, one for when t is greater than 72 and one for when t is less than 72:
t - 72 < 2 and -(t - 72) < 2
Simplifying these inequalities, we get:
t < 74 and t > 70
Therefore, the range of possible actual temperatures is 70°F < t < 74°F.

Quadrilateral JKLM is a parallelogram. What is the m∠KJN?
we can deduct that the angle on the L vertex is 25°, because that way all three angles will result in 180°.
We know that JKLM is a parallelogram, which means that its opposite sides are parallels, such that: JK // ML and JM // KL.
So, we know that the angle MLJ equals 25°, and JK // ML, from this we can say that angles LJK and MLJ are equal, because they are ''internal alternate angles'', since that they are inside the parallels.
So, angle LJK is 25, and JKL is a triangle, which has the angle at K vertex equal to 130°. We know that internal angles in a triangle must sum 180°.
Since that, two angles, in the triangle JKL, measure 130° + 25° = 155°; we can deduct that the angle on the L vertex is 25°, because that way all three angles will result in 180°.

The y-intercept of the graph of y=-7x+140y is located at (0, c) What is the value of c ?
The y-intercept of the graph is located at (0, 0). So, the value of c is 0.
What is graph?
A graph is a visual representation of data that displays the relationship between two or more variables. It consists of a set of points, called vertices or nodes, which are connected by lines or curves, called edges or arcs. The vertices represent the variables, while the edges represent the relationship between them.
To find the y-intercept of the graph of y = -7x + 140y, we need to substitute x = 0 into the equation and solve for y. This will give us the y-coordinate of the point where the graph intersects the y-axis.
Substituting x = 0, we get:
y = -7(0) + 140y
y = 140y
Simplifying the equation, we get:
139y = 0
Dividing both sides by 139, we get:
y = 0
Therefore, the y-intercept of the graph is located at (0, 0). So, the value of c is 0.

In a seasonal-growth model, a periodic function of time is introduced to account for seasonal variations in the rate of growth. Such variations could, for example, be caused by seasonal changes in the availability of food. (a) Find the solution of the seasonal-growth model where k, r, and ϕ are positive constants.

(a) The solution of the seasonal-growth model is
P(t) = P0[tex]e^{(k/r sin(rt))}[/tex]
(b) After solving we get [tex]\lim_{t \to \infty} P(t)[/tex] = NONE . As, t approaches to infinity
(a) To solve the differential equation DP/dt = kPcos(rt-[tex]\theta[/tex]),
The variables can be split apart and integrat:
∫(1/P) dP = ∫k cos(rt-[tex]\theta[/tex] ) dt
ln|P| = (k/r)sin(rt- [tex]\theta[/tex] ) + C
where
C is the constant of integration.
By solving for P, we get:
P(t) = [tex]e^{(k/r sin(rt- \theta ) + C)}[/tex]
We can determine the value of C by using the initial condition P(0) = P0:
P(0) = [tex]e^{(k/r sin(- \theta) + C)}[/tex]= P0
C = ln(P0) - (k/r)sin(-[tex]\theta[/tex] )
C = ln(P0) + (k/r)sin([tex]\theta[/tex] )
By substituting this into the expression for P(t), we get:
P(t) = [tex]e^{(k/r sin(rt-\theta) + ln(P0) + (k/r)sin(\theta))}[/tex]
By simplifying, we get:
P(t) = P0[tex]e^{(k/r sin(rt-\theta) + k/r sin(\theta))}[/tex]
P(t) = P0[tex]e^{(k/r sin(rt))}[/tex]
(b) We must take into account the behavior of sin(rt) as t approaches infinity in order to determine the limit of P(t) as t approaches infinity. Sin(rt) will fluctuate between -1 and 1 as t grows because the sine function oscillates between -1 and 1.
As a result, the term [tex]e^{(k/r sin(rt))}[/tex] will bounce between [tex]e^{(-k/r)}[/tex] and [tex]e^{(k/r)}[/tex] as t approaches infinity, but it won't converge to a single value.
As a result, there is no P(t) limit as t approaches infinity.
Hence, the answer is:

35 POINTS HELP
There are four numbers: 8, 15, 100 and 123.
What is number?Number is a mathematical object used to count, measure, and label. It is used in many different contexts, from everyday life to scientific research. Numbers can be represented in various forms, such as symbols, digits, and words. They are used to represent quantities, distances, time, and other concepts. Numbers can also be used to represent relationships, such as equations, which are statements that describe how two or more things are related.
To solve this problem, it is best to line the numbers up on the y axis or x axis. To multiply the numbers, start by multiplying the numbers on the y axis first. So, 8 x 15 = 120. Then, multiply the result by the number on the x axis which is 100. 120 x 100 = 12,000. Finally, multiply 12,000 by the last number on the x axis which is 123. 12,000 x 123 = 1,476,000. Therefore, the answer to the problem is 1,476,000.

What is the slope of the line that passes through the points (6, 10)(6,10) and (6, -2)(6,−2)?
The slope of the line that passes through the points (6,10) and (6,−2) is undefined.
The slope of a line is defined as the ratio of the vertical change (rise) to the horizontal change (run) between any two points on the line. In mathematical terms, the slope of a line passing through two points (x₁, y₁) and (x₂, y₂) is given by the formula:
slope = (y₂ - y₁) / (x₂ - x₁)
Now, let's apply this formula to the given points (6, 10) and (6, -2). Here, x₁ = 6, y₁ = 10, x₂ = 6, and y₂ = -2. Substituting these values in the formula, we get:
slope = (-2 - 10) / (6 - 6)
Notice that the denominator is zero, which means that the line is a vertical line. In this case, the slope is undefined.

Which graph shows the solution to the inequality? x − (5 − 3x) ≤ 2x − 1 A. A number line with a closed dot at 2 shaded to the left. B. A number line with a closed dot at 2 shaded to the right. C. A number line with a closed dot at negative 1 shaded to the left. D. A number line with a closed dot at negative 1 shaded to the right.
Answer: To solve the inequality x − (5 − 3x) ≤ 2x − 1, we need to simplify it by first distributing the negative sign in front of the parentheses, and then combining like terms. This gives us:
x - 5 + 3x ≤ 2x - 1
4x - 5 ≤ 2x - 1
Next, we can isolate the variable on one side of the inequality by subtracting 2x from both sides:
4x - 2x - 5 ≤ -1
2x - 5 ≤ -1
Finally, we can isolate x by adding 5 to both sides and dividing by 2:
2x ≤ 4
x ≤ 2
So the solution to the inequality is x ≤ 2.
To graph this solution on a number line, we can put a closed dot at 2 and shade to the left of it, since all values less than or equal to 2 satisfy the inequality. Therefore, the correct graph is A, a number line with a closed dot at 2 shaded to the left.

Revenue When a wholesaler sold a product at $40 per unit, sales were 300 units per week. After a price increase of $5, however, the average number of units sold dropped to 275 per week. Assuming that the demand function is linear, what price per unit will yield a maximum total revenue?
The price per unit that yields maximum revenue is $400.
We can start by finding the demand function for the product. Since the demand is assumed to be linear, we can use two data points to find the equation of the line:
(40, 300) and (45, 275)
Using the point-slope form of a line, we get:
(275 - 300) / (45 - 40) = -5/25 = -1/5
y - 300 = (-1/5)(x - 40)
y = (-1/5)x + 320
where y is the number of units sold per week and x is the price per unit.
The revenue function is simply the product of the price and the number of units sold:
R = xy
Substituting the demand function, we get:
R = x(-1/5)x + 320x
Simplifying, we get:
R = -1/5x^2 + 320x
To find the price per unit that yields maximum revenue, we need to take the derivative of the revenue function with respect to x and set it equal to zero:
dR/dx = -2/5x + 320 = 0
Solving for x, we get:
x = 800/2 = $400

b)1300
a) Sample size 13:(43.614, 44.386)
b) Sample size 1300:(43.9663, 44.0337)
The weight of the screws is normally distributed and has a variance of 0.64g^2. In a sample, the mean of the screws was 44g. The following are the two-sided (symmetrical) confidence intervals with a 95 percent confidence level for the expected value of the weight:Option a) Sample size 13:For a sample size of 13, the standard error of the mean is calculated as follows:SE = σ/√nwhere SE is the standard error, σ is the variance, and n is the sample size.In this case, SE = √(0.64)/√(13) = 0.1772.The t-distribution should be used to calculate the confidence interval since the population's standard deviation is unknown.The t-value corresponding to the 95% confidence interval with 12 degrees of freedom (df = n – 1) is 2.179. Therefore, the confidence interval can be calculated as follows:44 ± 2.179(0.1772)= 44 ± 0.386= (43.614, 44.386)The expected weight of the screws in the population is estimated to be between 43.614 g and 44.386 g.Option b) Sample size 1300:For a sample size of 1300, the standard error of the mean is calculated as follows:SE = σ/√nwhere SE is the standard error, σ is the variance, and n is the sample size.In this case, SE = √(0.64)/√(1300) = 0.0172.The z-distribution should be used to calculate the confidence interval since the sample size is large enough to assume that the sample mean is approximately normally distributed.The z-value corresponding to the 95% confidence interval is 1.96. Therefore, the confidence interval can be calculated as follows:44 ± 1.96(0.0172)= 44 ± 0.0337= (43.9663, 44.0337)The expected weight of the screws in the population is estimated to be between 43.9663 g and 44.0337 g.

What is an effective example of cardinality?
A's cardinality is equivalent to its element count if A has a finite amount of elements. Say |A|=5 if A=2, 4, 6, 8, 10. The outcome of a numbering process is referred to as "cardinality". A set's cardinality is determined by the number of components in it. For illustration, the group 1, 2, 3, 4, and 5 has a greater cardinality of five than the set 1, 2, 3, and 5, each of which has an attributes of three.
Here,
a)
I "Chinese New Year of 2023" has one cardinal element, making it one-dimensional.
ii) Since there are three elements in S and each element can either be included in a subset or not, the power set P(S) of S=1,,apple has 23 = 8 elements.
iii) xRx2=3 has two components because the squares of two real numbers, 3 and -3, are both 3.
iv) Since "0" is regarded as one element and there are five other distinct elements in the collection, {{0,1,2},3,4,5,∅,{{0}}} has six elements.
b)
=> A={0,1,2}, B={apple}, and C={apple}
The set difference between C and A is only the element 0, which is absent from C, so A=apple0,1,2=apple.
Consequently, A, B, and C include the following components:

Carlos operates a pizzeria in Chicago. If the diameter of a large pie at his restaurant is 24 inches, what would be the area of one slice (if every pizza is cut into 8 equal slices)?
ROUND ANSWER TO THE NEAREST TENTH OF AN INCH
The area of one slice of a large pizza with a diameter of 24 inches is 56.52 square inches.
The formula for calculating the area of a circle is A = πr^2, where A is the area of the circle, π is the constant pi (3.1415) and r is the radius of the circle. To calculate the area of a slice, we must first calculate the radius of the pizza. To do this, we divide the diameter of the pizza (24 inches) by 2, which yields a radius of 12 inches.
Now that we have the radius, we can calculate the area of one slice. Plugging the radius of 12 inches into the equation, we get A = 3.1415*12^2 = 452.16 square inches. Since each pizza is cut into 8 equal slices, each slice would have an area of 452.16/8 = 56.52 square inches.

How to calculate a rate or unit rate?
To calculate a rate, divide two quantities with different units; to calculate a unit rate, divide a rate by the quantity being measured.
What is rate ?
In mathematics, a rate is a ratio that compares two quantities with different units. It is typically expressed as the amount of change of one quantity with respect to another quantity. Rates are often used in the context of describing how quickly or slowly something changes over time or space.
To calculate a rate, we need to divide two quantities that have different units. For example, if we want to find the rate of a car's speed, we divide the distance traveled (in miles) by the time taken to travel that distance (in hours).
The formula for rate is:
rate = quantity / time
To calculate a unit rate, we need to divide a rate by the quantity being measured. For example, if the rate is the number of miles traveled per hour, the unit rate would be the number of miles traveled in one hour. To find the unit rate, we divide the rate by 1 hour.
The formula for unit rate is:
unit rate = rate / 1
When calculating rates or unit rates, it is important to make sure that the units of the quantities being divided are consistent. If the units are not the same, we need to convert them to the same unit before performing the division.
Therefore, to calculate a rate, divide two quantities with different units; to calculate a unit rate, divide a rate by the quantity being measured.

If the scale from DEF to D'E'F is 5:1 how much larger is the perimeter of D'E'F to DEF
the perimeter of D'E'F is 5 times larger than the perimeter of DEF.
If the scale from DEF to D'E'F is 5:1, then the corresponding side lengths are multiplied by a factor of 5 when going from DEF to D'E'F. This means that if the perimeter of DEF is P, then the perimeter of D'E'F is 5P.
To see why this is true, consider the perimeter of DEF:
P = DE + EF + FD
When we scale up by a factor of 5, we get:
D'E' + E'F' + F'D' = 5DE + 5EF + 5FD
= 5(DE + EF + FD)
= 5P
