which differential equation has a slope field with positive slopes in quadrants i and ii and negative slopes in quadrants iii and iv

Answer:

174 feet below sea level

Step-by-step explanation:

y is the number of minutes so you can multiply 14 by 9

14*9 is 126

then you add 126 to -300

126 + (-300) is essentially 126 - 300 and that is -174

the submarine was at 174 feet below sea level

In geometry, a disk (also spelled disc) is the place in a plane bounded by using a circle. A disk is stated to be closed if it consists of the circle that constitutes its boundary, and open if it does now not.

The disc turned into a round, flat item that Greek athletes would throw for distance in the course of the ancient Olympics, a wearing culture that continues within the present day Olympics with the spelling disc. The disc became a beneficial object of evaluation for some thing having a spherical, flat shape being referred to as a disc or disk.

Efficiently speaking, a circle has no region (it's far simply the brink), however a disc does. however in practice human beings think about a circle as the brink or the enclosed space, or both. A disc is "closed" when it includes the bounding circle, and open if it does no longer.

The equation x = z represents a line in three-dimensional space that passes through the origin and has a slope of 1.

The equation x = z represents a line in three-dimensional space. In this case, the line is a diagonal line that extends infinitely in both the positive and negative directions. It passes through the origin (0, 0, 0) and has a slope of 1.

To understand this visually, imagine a coordinate system with x, y, and z axes. The line x = z can be represented by points such as (1, 0, 1), (-2, 0, -2), (3, 0, 3), and so on. These points all lie on the line where the x and z coordinates are equal.

You can also think of this equation as saying that the x-coordinate of a point is always equal to its z-coordinate. So if you have a point like (2, 0, 2), the x and z coordinates are equal, satisfying the equation x = z.

In terms of the region represented by this equation, it's a straight line that extends infinitely in both the positive and negative directions in the x-z plane. All points on this line have the property that their x and z coordinates are equal.

The equation x = z represents a line in a three-dimensional coordinate system.

The equation x = z represents a line in a three-dimensional coordinate system. In this equation, the x-coordinate is always equal to the z-coordinate. This means that for any point on the line, the x-coordinate and the z-coordinate have the same value.

To understand this visually, imagine a three-dimensional coordinate system with x, y, and z axes. When x = z, it means that the points on the line have the same x and z values, while the y-coordinate can take any value. This line extends infinitely in both the positive and negative directions along the x and z axes.

For example, if we take the point (1, 2, 1) on this line, we can see that the x-coordinate (1) is equal to the z-coordinate (1). Similarly, if we take the point (-2, 5, -2), the x-coordinate (-2) is equal to the z-coordinate (-2).

In conclusion, the equation x = z represents a line in a three-dimensional coordinate system where the x-coordinate is always equal to the z-coordinate.

Step-by-step explanation:

Answer:

C. y = 4/5

Step-by-step explanation:

A line that is parallel to the x axis and perpendicular to the y axis will be a horizontal line.

Horizontal lines have a slope of 0, so the equation of the line will not have x in them.

Since horizontal lines will have a constant y value, the equation will have y = in the beginning.

So, C is the correct answer.

To prepare a 1000 mL of a 1:32 ratio bleach solution, you would need to mix 31.25 mL of bleach with 968.75 mL of water.

To calculate the amount of bleach needed to make a 1000 mL solution, we can set up the following proportion:

1 part bleach / 32 parts water = X mL bleach / 1000 mL total solution

Cross-multiplying, we get:

32X = 1000

Solving for X, we get:

X = 1000 / 32 = 31.25 mL of bleach

Therefore, to prepare a 1000 mL 1:32 bleach solution, you would need to mix 31.25 mL of bleach with 968.75 mL of water.

∠CED = 48°

Step-by-step explanation:

By adding all angles together, they’ll eventually equal ∠AED. Hence, sum of all given angles = ∠AED

∠AEB + ∠BEC + ∠CED = ∠AED

29°+12°+x = 89°

Solve for x and we will get measure of ∠CED:

41°+x = 89°

x = 89°-41°

x = 48°

Therefore, the measure of ∠CED is 48°

Therefore, the correct answer is: The median of 20 is the most accurate to use, since the data is skewed.

A histogram is a graphical representation of the distribution of a dataset. It is a visual representation of the frequency distribution of continuous or discrete data. The x-axis represents the range of values of the data and is divided into equal intervals called bins or buckets. The y-axis represents the frequency or count of the data values that fall into each bin.

The data in the histogram is skewed to the right, meaning that there are some high values that are pulling the mean up towards them. In this case, the mean is not an accurate measure of center because it is being heavily influenced by the two values of 55.

Therefore, the best measure of center to use in this case is the median, which is less sensitive to extreme values and gives a better representation of the typical donation received by the charity. In this case, the median donation is $20, which is a more accurate representation of the center of the data than the mean.

Therefore, the correct answer is: The median of 20 is the most accurate to use, since the data is skewed.

The probability that the sample proportion will be at least k is 0.7580.

Let P be the probability that any one person in the population will cooperate and respond to the questions. We are looking for the probability that at least k people out of n in the sample will cooperate and respond to the questions. Let X be the number of people who cooperate and respond to the questions in the sample. X follows the binomial distribution with parameters n and P.To calculate this, use the following formula:

Z = (X - μ) / σ

Here, X = number of people who cooperate and respond to the questions in the sample

μ = E(X) = np,  σ = sqrt(npq)

q = 1 - P

Now, to calculate the probability, first calculate μ = np =

σ = sqrt(npq)

Then, find the z-score using z = (k - μ) / σ.

Now, use the z-table to find the probability corresponding to the z-score obtained in the previous step. The probability obtained from the z-table is the probability that the sample proportion will be at least k.

The probability that the sample proportion will be at least k is 0.7580.

The correct option is 4 it lies on the 4th quadrant

The correct process for solving the equation 4(x − 8) = 24 and arriving at the correct solution is to distribute the 4, add 8 to both sides of the equation, and then divide both sides of the equation by 4. The solution is x = 8. The correct answer is D.

In the given equation, we have 4(x − 8) = 24. To solve this equation, we first distribute the 4 to the terms inside the parentheses: 4x − 32 = 24. Next, we add 32 to both sides of the equation to isolate the variable term: 4x = 56. Finally, we divide both sides of the equation by 4 to solve for x: x = 14.

From the answer choices provided, it is clear that option D describes the correct process. It correctly states to distribute the 4, add 8 to both sides of the equation (in this case, it should be 32), and then divide both sides of the equation by 4. The resulting solution is x = 8. Therefore, option D is the correct choice.

Rolling a 6-sided number cube (dice) is not a good way to answer a 20-question multiple-choice test if there are six choices for each question.

The reason is that rolling a dice only provides a random selection out of six possible choices, while each question on the test has six choices. Therefore, the probability of rolling the correct answer for each question is only 1 in 6 or approximately 16.67%.

Using a random method like rolling a dice does not allow for any knowledge or consideration of the content of the questions. It relies solely on chance, and the chances of getting the correct answer for each question are relatively low.

To increase the chances of answering the questions correctly, it is advisable to study the material, understand the concepts, and carefully read and analyze each question before selecting an answer. This will allow for a more informed and accurate selection of the correct choices on the test.
