Slope (m) of RH = 3/4

Distance of RH is d =5 units

Midpoint between points R and H is: M(1, 3.5)

Slope (m) = change in y / change in x = y2 - y1/x2 - x1, where:

R(3, 5) = (x1, y1)

H(-1,2) = (x2, y2)

Plug in the values

Slope (m) = (2 - 5) / (-1 - 3)

Slope (m) = (-3) / (-4)

Slope (m) of RH = 3/4

How to Find the Distance between two Points?

Distance formula used is: \(\sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}\)

R(3, 5) = (x1, y1)

H(-1,2) = (x2, y2)

Plug in the values

RH = √[(−1−3)² + (2−5)²]

RH = √[(−4)² + (−3)²]

RH = 5 units

How to Find the Midpoint?

The midpoint formula used is: M[(x2 + x1)/2, (y2 + y1)/2)

R(3, 5) = (x1, y1)

H(-1,2) = (x2, y2)

Substitute the values

M[(-1 + 3)/2, (2 + 5)/2)

M(1, 3.5)

Therefore,

Slope (m) of RH = 3/4

Distance of RH is d =5 units

Answer:

The answer is (H) because you multiply 25,500 by 15% hope its right.

Step-by-step explanation:

Answer:

81.5

Step-by-step explanation:

<G and <H are congruent

<F and <I are congruent

so the last two angles in both triangles must also be congruent

this means that <K and <J are congruent

so we can create this equation: <K = <J

substitute the angles with what we know: 4\(y^{2}\) = 6\(y^{2}\) - 40

add 40 to both sides and subtract 4\(y^{2}\) from both sides: 40 = 2\(y^{2}\)

you get: 20 = \(y^{2}\)

root square on both sides: \(\sqrt{20}\) = \(\sqrt{y^{2} }\)

you get: y ≈ 4.5

substitute this into one of the equations for a missing variable:

6\(y^{2}\) -----> 6 (4.5 x 4.5) - 40

6 ( 20.25) - 40

The limits of integration, [a, b], correspond to the x-values that define the region s.]

To find the volume of the solid when a region s is revolved about the x-axis, we can set up an integral expression using the method of cylindrical shells.

Let's consider a vertical strip within the region s, bounded by the x-values x=a and x=b. When this strip is revolved about the x-axis, it forms a cylindrical shell. The volume of this shell can be approximated by its height multiplied by its circumference, and then summed up for all the strips.

To set up the integral expression, we need to integrate the product of the circumference of the shell and its height over the range of x-values.

The integral expression to find the volume V is:

V = ∫[a, b] 2πx * h(x) dx

Where 2πx represents the circumference of the shell at a given x-value, and h(x) represents the height of the shell at that x-value.

Answer: Pigs = 21

Chicken = 45

Step-by-step explanation:

Let the pigs be represented by p

Let the chicken be represented by c.

From the question,

p + c = 66

4p + 2c = 174

4 × ( p + c = 66)

1 × (4p + 2c = 174)

4p + 4c = 264

- 4p + 2c = 174

2c = 90

c = 90/2 = 45

There are 45 chickens

Simce the farmer has a total of 66 animals, the number of pigs will be:

= 66 - 45

= 21 pigs

First replace x with -2 in the g(x) equation and solve:

The speed of sound is about 343 meters per second (or approximately 1,225 kilometers per hour).

The assertion you made appears to be incorrect. At sea level, the actual speed of sound is roughly 1,225 kilometres per hour, or 767 miles per hour.

The distance that sound travels through a medium, such air, in a predetermined length of time is known as the speed of sound. It is impacted by the medium's temperature, pressure, and humidity. The speed of sound is roughly 343 metres per second in dry air at 20 degrees Celsius (or approximately 1,225 kilometres per hour).

The integral will be the difference in the areas of the two curves: 1/2*(4sin(θ))^2 - 1/2*(2)^2.

The area inside the curve r = 4sin(θ) and outside the curve r = 2 can be represented by the integral of a certain expression.

To find the integral representing the area inside r = 4sin(θ) and outside r = 2, we need to set up an integral that calculates the area between the two curves in polar coordinates.

First, we determine the points of intersection between the two curves. Setting r = 4sin(θ) equal to r = 2, we can solve for the values of θ where the curves intersect. By analyzing the equation, we find that the curves intersect at θ = π/6 and θ = 5π/6.

Next, we set up the integral to calculate the desired area. The integral will have limits from θ = π/6 to θ = 5π/6, as this covers the region between the curves. The integral will be the difference in the areas of the two curves: 1/2*(4sin(θ))^2 - 1/2*(2)^2.

Evaluating this integral will yield the area inside r = 4sin(θ) and outside r = 2. By calculating the integral over the specified range of θ, the result will provide the desired area.

The study design in this scenario is a cross-sectional study. The study aims to examine the relationship between family status and school performance. The sample is selected by randomly choosing every 5th child from the list of children at the ABC elementary school. Data is collected from the school record for each child, and family status is operationalized by whether the child lives in a single-parent household, dual-parent household, or has a non-parent guardian in the household. The school performance is measured by administering a student math test and a student reading test to the child in April, with each test including 20 questions and each correct answer being worth five points.

To find the vector representing the path from plane A to plane B, we can subtract the coordinates of plane A from the coordinates of plane B.

The coordinates of plane A are (24, 18) and the coordinates of plane B are (8, 6).

Subtracting the coordinates:

Vector AB = (8 - 24, 6 - 18)

= (-16, -12)

Therefore, the vector representing the path from plane A to plane B is (-16, -12).

To find the actual distance between the planes, we can use the distance

formula:

Distance = √((x2 - x1)^2 + (y2 - y1)^2)

Using the coordinates of plane A (24, 18) and plane B (8, 6):

Distance = √((8 - 24)^2 + (6 - 18)^2)

= √((-16)^2 + (-12)^2)

= √(256 + 144)

= √400

= 20

Therefore, the actual distance between plane A and plane B is 20 units.

Given that the scale on the radar is 1 unit = 25 miles, the actual distance in miles would be:

Actual Distance = 20 units * 25 miles/unit

= 500 miles

So, the actual distance between plane A and plane B is 500 miles.

the derivative dy/dx is equal to 1/3 based on the given information. It's important to note that this calculation assumes that the partial derivatives (∂F/∂x) and (∂F/∂y) are not zero at the given point (z.y.a).

n the given problem, we have an implicit equation ln(x+y+z) = x+2y+3z that defines z as a function of x and y. We are given the values dy = (-1, 5, -3).

To find the derivative dy/dx, we can use the total derivative formula and apply it to the implicit equation. The total derivative is given by dy/dx = - (∂F/∂x)/(∂F/∂y), where F = ln(x+y+z) - x - 2y - 3z.

Differentiating F partially with respect to x and y, we have (∂F/∂x) = 1/(x+y+z) - 1 and (∂F/∂y) = 1/(x+y+z) - 2.

Plugging in the given values of dy = (-1, 5, -3), we can calculate dy/dx = - (∂F/∂x)/(∂F/∂y) = -(-1)/(5-2) = 1/3.

Therefore, the derivative dy/dx is equal to 1/3 based on the given information. It's important to note that this calculation assumes that the partial derivatives (∂F/∂x) and (∂F/∂y) are not zero at the given point (z.y.a).

We have,

To determine the number of different sundaes Julie can make by picking one flavor of ice cream, one kind of chocolate sauce, and one fruit topping, we need to multiply the number of options for each category.

Julie has 4 flavors of ice cream to choose from.

She has 2 kinds of chocolate sauce to choose from.

She has 5 different fruit toppings to choose from.

To calculate the total number of different sundaes, we multiply the number of options for each category:

Total number of different sundaes

= (Number of ice cream flavors) x (Number of chocolate sauce options) x (Number of fruit topping options)

Total number of different sundaes

The inequality's solution set can be described by inspection as x <= 8.

Inequality is the unequal treatment of people based on factors such as race, gender, class, or other social characteristics. It is often seen as unfair and can lead to social and economic disparities.

This is because the inequality (x-8)^(6)<=0 is asking when the quantity (x-8) raised to the 6th power is less than or equal to zero.

Since any number raised to an even power will always be positive or zero, the only way for this inequality to be true is when (x-8) is equal to zero. This occurs when x = 8. Therefore, the solution set is x <= 8.

To summarize, the inequality's solution set is:
