3 is the slope of the line between the pairs of points in each of the tables. Third table represents a linear function.

In mathematics, a line's slope, also known as its gradient, is a numerical representation of the line's steepness and direction. The word m is frequently used to represent slope; the reason for this is unclear, but it can be found in O'Brien's (1844)[2] and Todhunter's (1888) versions of the equation for a straight line, respectively, where it is written to be "y = mx + b" or "y = mx + c". The percentage of the "vertical difference" with the "horizontal change" among (any) two unique points on a line is used to compute slope. The ratio may occasionally be written as a quotient.

1)slope = y₂-y₁/x₂-x₁

         = -24/-8

         =3

2)slope = y₂-y₁/x₂-x₁

         = 13/3

Some alkenes have geometric cis-trans isomers because of the presence of a double bond between two carbon atoms. In a carbon-carbon double bond, the carbon atoms are connected to two different groups of atoms, which can be oriented differently in space. In the cis configuration, the two substituent groups on each carbon atom are on the same side of the double bond, while in the trans configuration, the two substituent groups on each carbon atom are on opposite sides of the double bond.

The cis-trans isomerism arises due to the restricted rotation around the carbon-carbon double bond. In the case of cis isomers, the substituent groups are too bulky to rotate around the double bond, and they remain on the same side of the double bond. In contrast, in the trans isomers, the substituent groups are oriented on opposite sides of the double bond, which allows them to rotate freely around the bond.

The presence of cis-trans isomers has important consequences for the physical and chemical properties of alkenes, including their reactivity, solubility, and melting points. The two isomers can have different properties and can exhibit different biological activities, making them important targets for drug design and synthesis.

The domain of the function y = (2x - 3) / ( |x-1| + 2) is all real numbers except x = 1 and x = 3.

The expression inside the absolute value bars, |x-1|, can be either positive or negative, depending on the value of x. Thus, we have two cases to consider:

Case 1: x-1 ≥ 0, or x ≥ 1

In this case, |x-1| = x-1, and the function becomes:

y = (2x - 3) / (x-1 + 2) = (2x - 3) / (x+1)

Case 2: x-1 < 0, or x < 1

In this case, |x-1| = -(x-1) = 1-x, and the function becomes:

y = (2x - 3) / (1-x + 2) = (2x - 3) / (3-x)

1 gram is equal to 0.001 kilogram.
To convert grams to kilograms, divide grams by 1000.

Answer. The correct option is (E). 9.5 and 14.5

Explanation for step 1This is because 95% of the mean weights from samples of size 100 cats from this population will fall between 9.5 and 14.5 pounds. The other answers are incorrect because they do not fall within the range of 95% of the mean weights from samples of size 100 cats from this population

About 95% of the mean weights from samples of size 100 cats from this population would fall between approximately 11.51 pounds and 12.49 pounds.

To determine the range within which 95% of the mean weights from samples of size 100 cats would fall, we can use the concept of the confidence interval.

Given:

Population mean weight (μ) = 12 pounds

Population standard deviation (σ) = 2.5 pounds

Sample size (n) = 100 cats

Since the population distribution is assumed to be approximately normal, the sampling distribution of sample means will also be approximately normal. To calculate the range, we can use the formula for the confidence interval:

Confidence Interval = sample mean ± (z * standard error)

The standard error can be calculated using the formula:

Standard Error = σ / √n

Using a 95% confidence level, the corresponding z-value is approximately 1.96 (obtained from standard normal distribution table).

Plugging in the values:

Standard Error = 2.5 / √100 = 0.25

Confidence Interval = 12 ± (1.96 * 0.25)

Calculating the values:

Lower limit = 12 - (1.96 * 0.25) ≈ 11.51 pounds

Upper limit = 12 + (1.96 * 0.25) ≈ 12.49 pounds

If there had been 2 more students in the club, each would have had to contribute 50 cents less, there were 18 students in the math club.

Let's assume that initially, there were 'x' students in the math club. Each student contributed an equal amount to purchase a $72 calculator, so each student's contribution was 72/x dollars.

According to the given information, if there had been 2 more students in the club, each student would have had to contribute 50 cents less. This means that the new contribution per student would be (72/x) - 0.50 dollars.

We can set up the equation:

72/x - 0.50 = 72/(x+2)

To simplify the equation, we can multiply both sides by x(x+2) to eliminate the denominators:

72(x+2) - 0.50x(x+2) = 72x

Expanding and rearranging terms:

72x + 144 - 0.50x² - x = 72x

Rearranging again:

0.50x² - x - 144 = 0

Now we can solve this quadratic equation. By factoring or using the quadratic formula, we find that x = 18 or x = -16. However, since the number of students cannot be negative, the solution is x = 18.

The rhombus-shaped cookie cutter has diagonals of 10 centimeters and 6.7 centimeters. We can use the formula for the area of a rhombus, which is A = (d1 * d2)/2, where d1 and d2 are the lengths of the diagonals.

So, the area of the cookie cutter is A = (10 * 6.7)/2 = 33.5 square centimeters.  Since Alejandro wants to ice the tops of 16 cookies, we need to find the total area of the tops of the cookies. If we assume that each cookie is a rhombus with the same shape as the cookie cutter, then each cookie has an area of (10 * 6.7)/2 = 33.5/2 = 16.75 square centimeters.  Therefore, the total area that needs to be covered in icing is 16 * 16.75 = 268 square centimeters. Rounded to the nearest square centimeter, the total area is 268 square centimeters.

What is the solution to log eˣ ⁻ ³ = 7

Answer:

SA = 152 ft²

Step-by-step explanation:

First, we can solve for the area of the base (the side closest to us):

A(triangle) = (1/2) · base · height

A(base) = (1/2) · 6 · 4

A(base) = 3 · 4

A(base) = 12

Then, we can solve for the area of the left and right sides:

A(rect) = length · width

A(side) = 8 · 5

A(side) = 40

Next, we can solve for the area of the bottom side:

A(rect) = length · width

A(bottom) = 8 · 6

A(bottom) = 48

Finally, we can solve for the surface area of the tent by adding all of the sides' areas together:

SA = [ 2 · A(base) ] + [ 2 · A(side) ] + A(bottom)

SA = [2 · 12] + [2 · 40] + 48

SA = 24 + 80 + 48

SA = 152 ft²

The rule that represents the dilation of the original triangle with a scale factor of 12 centered at the origin is (x, y) → (12x, 12y).

The coordinates of the vertices of the original equilateral triangle can be found by dividing the perimeter by the length of each side, which is 4/3. Thus, each vertex is located at a distance of 4/3 units from the adjacent vertices.

Let's assume that the original triangle is centered at the origin (0,0) and its vertices are (2/3, 0), (-1/3, √3/3), and (-1/3, -√3/3).

Multiply the x and y coordinates of each vertex by the scale factor of 12.

Thus, the vertices of the dilated triangle would be:

(2/3) × 12, 0 × 12 = (8, 0)

(-1/3) × 12, √3/3 × 12 = (-4, 2√3)

(-1/3) × 12, -√3/3 × 12 = (-4, -2√3)

These transformations result in the graph of g(x), which is a horizontally reflected, horizontally compressed, horizontally shifted, and vertically shifted version of the parent function f(x) = log(x).

To achieve the graph of g(x) = log("-2x" - 4) - 1 from the parent function f(x) = log(x), several transformations are applied.

First, a horizontal reflection occurs due to the negative coefficient in front of the x term, "-2x". This reflection flips the graph of f(x) across the y-axis.

Next, a horizontal compression takes place due to the coefficient of 2 in "-2x". This compression squeezes the graph horizontally, making it narrower compared to the parent function.

Then, a horizontal shift to the right occurs by 4 units due to the constant term -4. This shift moves the graph horizontally, shifting it to the right.

Lastly, a vertical shift downward by 1 unit takes place due to the constant term -1. This shift moves the entire graph vertically, shifting it downward.

The length and width of the new rectangle would be 3 inches and 4 inches, respectively.

Let's consider the original rectangle. We know that its area is 10 square inches and its perimeter is 14 inches. Let's denote the length of the original rectangle as L and the width as W.

The area of a rectangle is given by A = L * W, and the perimeter is given by P = 2 * (L + W). We have two equations based on the given information:

Equation 1: L * W = 10

Equation 2: 2 * (L + W) = 14

From Equation 2, we can simplify it to L + W = 7 and rewrite it as W = 7 - L. Substituting this value into Equation 1, we get L * (7 - L) = 10.

Expanding and rearranging the equation, we have L^2 - 7L + 10 = 0. Factoring the equation, we find (L - 5)(L - 2) = 0.

Therefore, L = 5 or L = 2. If L = 5, then W = 7 - L = 2. If L = 2, then W = 7 - L = 5.
