The reflection's rule is described below. The right response is x-axis (x, y) = (x, -y).

When we gaze at our own reflection in a mirror, we naturally think of a reflection as a mirror image.

In maths, the concept of reflection and a mirror image are comparable.

The rules for reflection across the y-axis and x-axis are fundamental transformations in geometry. The rule for reflection across the y-axis is (x, y) → (-x, y), which means that every point's x-coordinate is negated while the y-coordinate remains the same. This transformation has the effect of reflecting the object or figure across the y-axis.    

Similarly, the rule for reflection across the x-axis is (x, y) → (x, -y), which means that every point's y-coordinate is negated while the x-coordinate remains the same. This transformation has the effect of reflecting the object or figure across the x-axis. These transformations are important in many areas of mathematics and science, including computer graphics and physics.

Henry had 35/6 gallons of juice, which is equivalent to 5 and 5/6 gallons.

To convert quarts to gallons, we need to know that there are 4 quarts in 1 gallon. So, we divide the number of quarts by 4 to get the number of gallons.

In this problem, we're given that Henry had 23 1/3 quarts of juice. To convert this amount to gallons, we first need to convert the mixed number to an improper fraction. We can do this by multiplying the whole number by the denominator of the fraction and then adding the numerator. This gives us:

23 1/3 = (23 × 3 + 1) / 3 = 70 / 3

Now we can divide 70/3 by 4 to get the amount of juice in gallons:

70/3 ÷ 4 = 70/3 × 1/4 = 70/12

We can simplify this fraction by dividing both the numerator and denominator by their greatest common factor, which is 2 in this case. This gives us:

70/12 ÷ 2/2 = 35/6

So, Henry had 35/6 gallons of juice in total.

Step-by-step explanation:

Let's assume, that apples cost x dollars per pound and oranges cost y dollars per pound.

Let's write 2 equations according to the given information and put them in a system:

{3x + 4y = 3,45,

{4x + 2y = 3,10;

Let's make x the subject from the 1st equation:

3x = 3,45 - 4y / : 3

x = 1,15 - 1 1/3y

Let's replace x in the 2nd equation:

The new location of Point A is (3, 5). This is because the x-coordinate remains unchanged, while the y-coordinate is inverted, making it positive.

Point A is located at (3, -5). To reflect this point over the x-axis, we need to calculate the new coordinates. First, we will note that the x-coordinate remains unchanged. This means that the new x-coordinate is 3. Secondly, we will note that the y-coordinate needs to be flipped, meaning it will become positive. To do this, we will take the opposite of the original y-coordinate. Since the original y-coordinate is -5, the new y-coordinate will be 5. Therefore, the new location of Point A is (3, 5).

The insurance company will pay a total of  $70,000 in damages as insurance.

What exactly is insurance?

Insurance is a contract between an individual or entity (the insured) and an insurance company (the insurer) in which the insurer agrees to provide financial protection or compensation to the insured in any loss or damage. The insured typically pays a premium to the insurer in exchange for this protection. Insurance policies can provide coverage for various risks, such as accidents, illness, property damage, and liability.

Now,

Theresa's insurance policy covers up to $25,000 for bodily injury per person, up to $50,000 total for bodily injury per accident, and up to $25,000 for property damage per accident.

For bodily injury, the insurance will cover $25,000 for the first passenger, $10,000 for the second passenger, and $10,000 for Theresa's son, which adds up to $45,000. Since this is below the $50,000 total for bodily injury per accident, the insurance will cover all the bodily injury damages.

For property damage, the insurance will cover up to $25,000 per accident. Since the total property damage is $18,000 + $7,500 = $25,500, which is above the $25,000 coverage limit, the insurance will only pay out $25,000.

Therefore, the insurance company will pay a total of $45,000 + $25,000 = $70,000 in damages.

The length of the edge of the square is increasing at a rate of 12/13 cm/min when the area is 169 cm^2, given that the area of the square is increasing at a rate of 24 cm^2/min.

Let's assume that the side length of the square is represented by "x" and the area of square is represented by "A". Then we have:

A = x^2

Differentiating both sides with respect to time "t", we get:

dA/dt = 2x(dx/dt)

Given that dA/dt = 24 cm^2/min, we can find dx/dt when A = 169 cm^2 (which is the area of a square with side length of 13 cm):

24 = 2(13)(dx/dt)

Simplifying this expression, we get:

dx/dt = 24/(26) = 12/13

there are 9 office suites in company C and the total number of office suites in the three companies is 75.   To solve this problem, we first need to find out how many office suites company A and company B have. Let's represent the total number of office suites in the three companies as x.

Company A has 1/3 of the computers, which means they have 1/3 of the office suites as well. So the number of office suites in company A is:

1/3 * x = x/3

Company B has 2/5 of the computers, which means they have 2/5 of the office suites as well. So the number of office suites in company B is:

2/5 * x = 2x/5

To find out how many office suites are in company C, we can use the fact that the total number of office suites is 60. So we can write an equation:

x/3 + 2x/5 + C = 60

We can simplify this equation by finding a common denominator for the first two terms:

5x/15 + 6x/15 + C = 60

11x/15 + C = 60

Now we can solve for C by isolating it on one side of the equation:

C = 60 - 11x/15

To find the value of x, we can use the fact that the total number of office suites is 60:

x/3 + 2x/5 + (60 - 11x/15) = 60

Multiplying both sides by 15 to eliminate the denominator, we get:

5x + 6x + 900 - 11x = 900

Simplifying, we get:

x = 75

So the total number of office suites in the three companies is 75. To find out how many are in company C, we can substitute x into the equation we found for C:

C = 60 - 11x/15 = 60 - 11(75)/15 = 9

Therefore, there are 9 office suites in company C.

Abd is an abbreviation for the term "abdomen." It is used to describe the part of the body located between the chest and the pelvis, and contains many vital organs including the stomach, intestines, pancreas, and liver. Abd is often used in medical terminology, particularly when referring to conditions that affect the abdomen such as appendicitis or diverticulitis.

The measure of ABD is (0.3x+67) and the measure of CBD is (0.1x+41). Since the two angles are supplementary (they add up to 180 degrees), we can set the two equations equal to each other and solve for x.
0.3x + 67 = 0.1x + 41
Subtracting 0.1x from both sides of the equation, we get:

Probability is a measure of the likelihood of an event occurring. It is a number between 0 and 1, with 0 indicating that an event is impossible and 1 indicating that an event is certain to occur. The probability of an event is calculated by dividing the number of ways an event can occur by the total number of possible outcomes.

In Mathematics, interquartile range (IQR) is the difference between quartile 1 (Q₁) and quartile 3 (Q₃):

IQR = Q₃ - Q₁

Based on the given data set, we can logically deduce the following interquartile ranges:

Quartile 3 (Q₃) = 8

Quartile 1 (Q₁) = 6

Now, the interquartile range (IQR) can be calculated as follows:

Interquartile range (IQR) = Q₃ - Q₁

Interquartile range (IQR) = 8 - 2

Interquartile range (IQR) = 2

Based on the 1.5 × IQR rule for outliers, we have:

The height of the main cable 20 meters from the center is 16 meters above the road.

To find the equation of the parabola, we need to use the information given about the height of the cables at the towers and the center of the bridge. We know that the main cables are 20 meters above the road at the towers, so we can use this information to find the distance between the towers, which is

distance between towers = 80 meters - 2(20 meters) = 40 meters

We also know that the main cables are 4 meters above the road at the center, so we can use this information to find the height of the vertex of the parabola, which is

vertex height = 4 meters + 20 meters = 24 meters

We can now use the vertex form of a parabola to write the equation

y = a(x - h)^2 + k

where (h, k) is the vertex and a is a constant that determines the shape of the parabola.

Substituting the values we found for the vertex height and the distance between the towers, we get

y = a(x - 40)^2 + 24

We now need to find the value of a. To do this, we can use the fact that the vertical cables are spaced every 10 meters. This means that the distance between the vertex of the parabola and a point on the main cable 10 meters from the center of the bridge is

distance = 10 meters

Substituting x = 50 (since the center of the bridge is at x = 40 + 10 = 50) and y = 14 (since the cable is 4 meters above the road at this point), we get

14 = a(50 - 40)^2 + 24

-10 = 100a

a = -0.1

Substituting this value of a into the equation we found earlier, we get

y = -0.1(x - 40)^2 + 24

To find the height of the main cable 20 meters from the center, we can substitute x = 60 (since the center of the bridge is at x = 50 and we want to go 20 meters to the right) into the equation

y = -0.1(60 - 40)^2 + 24

y = -0.1(20)^2 + 24

y = -0.1(400) + 24

y = -40 + 24

using the tangent ratio in the right triangle

tan29° =[tex]\frac{opposite}{adjacent}[/tex] = [tex]\frac{x}{28}[/tex] ( multiply both sides by 28 )

The direct variation equation that shows the relationship between x and y, where y = 20 when x = 5, is y = 4x.

In a direct variation, the relationship between two variables can be described by the equation y = kx, where y and x are the variables and k is the constant of variation. This equation indicates that y varies directly with x, which means that as x increases or decreases, y also increases or decreases proportionally.

To find the constant of variation, we need to use the given information about the values of y and x. In this case, we are told that when x = 5, y = 20. We can substitute these values into the direct variation equation:

y = kx

20 = k(5)

To solve for k, we divide both sides by 5:

k = 20/5

Simplifying this expression, we get:

k = 4

Therefore, the direct variation equation that shows the relationship between x and y is:

y = 4x

This equation means that for any value of x, if we multiply it by 4, we will get the corresponding value of y. For example, if x = 2, then y = 4(2) = 8. If x = 10, then y = 4(10) = 40. In other words, y is always four times the value of x in a direct variation relationship.

In the field of mathematics, a recurrent equation is a formula that determines the nth value of a sequence of numbers based on a combination of previous values. Typically, the equation only involves k past values of the sequence, where k is a constant parameter independent of n; this k is known as the recurrence order. These equations, also known as difference equations, describe a sequence or array in terms of itself through recursion. They establish a relationship between the dependent variable and the differences of various orders of the variable. Recurrent equations can be utilized to model the runtime of recursive programs by distinguishing between recursive and non-recursive operations.

If the speed of the camp counselor is 55 miles per hour, then we can use the formula distance = speed × time

 Find out  long it will take for the counselor to reach the campground?

Let’s set distance = 0 and solve for t:

245-5t = 0

55t = 245

t =  4.45hours

Therefore, it will take approximately 4.45 hours for the camp counselor to reach the campground.

The probability that at least 50 respondents of a random sample of 100 Mississippi residents do not identify themselves as conservative is 0.9989, or approximately 99.89%.

What is binomial distribution?

A binomial distribution is a type of distribution distinct from a continuous distribution in which every trial has an equal chance of reaching a given value and is independent of every other trial. The binary distribution has only two possible outcomes.

This is a binomial distribution problem with n = 100 (sample size) and p = 0.4278 (the probability of not identifying as conservative, which is 1 - 0.572).

The probability of at least 50 respondents not identifying themselves as conservative can be calculated using the cumulative distribution function (CDF) of the binomial distribution:

P(X ≥ 50) = 1 - P(X < 50)

Using a binomial calculator or software, we can find that P(X < 50) = 0.0011.

Therefore,

P(X ≥ 50) = 1 - P(X < 50) = 1 - 0.0011 = 0.9989

So, the probability that at least 50 respondents of a random sample of 100 Mississippi residents do not identify themselves as conservative is 0.9989, or approximately 99.89%.

a.  the equation showing the relationship between s and r:

6s + 2r = 21

b.  the equation that shows the rearrangement of r as a function of s:

r = (21/2) - 3s

c. If it takes Diego 1.2 seconds to spin around each time, the total time he spends spinning is r = 5.7 seconds

The equation showing the relationship between s and r: 6s + 2r = 21

The equation that shows the rearrangement of r as a function of s:

2r = 21 - 6s

r = (21/2) - 3s

c., the total time Diego spends spinning is:

6s = 6(1.2) = 7.2 seconds

Applying the equation in part (b), we can find the time he spends running:

r = (21/2) - 3s

r = (21/2) - 3(1.2)

r = 5.7 seconds
