A vertical line in geometry is one that crosses the page from top to bottom.

What is meant by horizontal and vertical segments?

A vertical line in geometry is one that crosses the page from top to bottom. Its cousin is the horizontal line that spans the page from left to right. A horizontal line and a vertical line are perpendicular.

Businesses utilize segmentation as a marketing strategy to focus on a certain market segment or type of customer. While vertical segmentation sharpens your marketing emphasis to target customers in a smaller demographic, horizontal segmentation entails offering a product to a broad range of consumers.

A horizontal object is one that is perpendicular to the horizon. Due to the fact that vertical is the polar opposite of horizontal, anything that forms a 90° (right angle) with either the horizontal or the horizon is referred to as vertical. This means that the horizontal line is one that crosses from left to right. Mathematical applications of the horizontal and vertical.

Therefore, the correct answer is option C. (5.-4) and (-2, 3).

what is the greatest possible error of 4700

Answers

The greatest possible error of 4700 is equal to 2,350.

What is precision?

In Mathematics, precision can be defined as a quality which is independent of accuracy because it only describes how close together are numerical values that are obtained in a series of measurements.

What is the greatest possible error (GPE)?

In Mathematics, the greatest possible error (GPE) of a measurement can be defined as one-half of the value of a given smallest measuring unit, or one-half of a given precision.

This ultimately implies that, the greatest possible error (GPE) of a measurement can calculated by dividing the precision by two and this is represented by this mathematical expression;

Greatest possible error (GPE) = precision/2

Greatest possible error (GPE) = 4700/2

Greatest possible error (GPE) = 2,350.

What is the sum of 6 of the interior angles of a regular decagon​

Answers

The sum of the interior angles of a decagon is 1440 degrees.

What is meant by regular decagon?

The inner angles of a normal decagon are equal. Every interior angle in a normal decagon is 144° in length because 1440°/10 = 144°. Additionally, each external angle measures 36°.

A decagon is a ten-sided polygon, or ten-gon, in geometry. A basic decagon's inner angles add up to 1440°, and its external angles add up to 360°.

A decagon is a polygon with ten sides, ten internal angles, and ten vertices, or points where the sides meet. There are 10 equal-length sides and 10 equal-sized interior angles in a normal decagon. The sum of all the angles, each of which is 144°, is 1,440°.

A decagon is a polygon having 10 sides.

The sum of interior angles of a polygon having 'n' sides is (2n- 4) × 90°.

sum of interior angles of a decagon= (204) × 90°

= 16 x 90°

= 1440°

Therefore, the sum of the interior angles of a decagon is 1440 degrees.

a. 2,411.5 cm
b. 12,057.6 cm³
c. 3,014.4 cm³
d. 9,646.1 cm³

Answers

The volume of this cone is equal to: A. 2,411.5 cm³.

How to calculate the volume of a cone?

Mathematically, the volume of a cone can be calculated by using this formula:

V = 1/3 × πr²√(l² - r²)

l represents the slant height.r represents the radius.

Radius = diameter/2 = 24/2 = 12 cm.

Substituting the given parameters into the volume of a cone formula, we have;

Volume of a cone, V = 1/3 × 3.142(12)²√(20² - 12²)

Volume of a cone, V = 1/3 × 3.142(144)×√(400 - 144)

solve the given differential equation by undetermined coefficients. y'' + 2y = −18x2e2x

Answers

The general solution to the differential equation y'' + 2y = −18x^2e^(2x) by undetermined coefficients is y = (-9x^2)e^(2x).

The given differential equation is y'' + 2y = −18x^2e^(2x)

To solve this equation by undetermined coefficients, we first find the characteristic equation of the homogeneous equation, which is r^2 + 2 = 0.

The solutions to this equation are r = i and r = -i. Therefore the general solution to the homogeneous equation is yh(x) = c1 cos(x) + c2 sin(x)

Now, we use the method of undetermined coefficients to guess the form of the particular solution. Since the non-homogeneous term is −18x^2e^(2x), we guess that the particular solution is of the form

yp = (Ax^3 + Bx^2)e^(2x) + Cx^2e^(2x).

Substituting this into the differential equation, we get

y'' + 2y = (6Ax + 2B)e^(2x) + 2Cxe^(2x) = −18x^2e^(2x)

Equating the coefficients of the like terms, we get:

6A = 0, 2B = −18, and 2C = 0

Solving for A, B and C, we get A = 0, B = −9 and C = 0

Therefore, the general solution to the differential equation y'' + 2y = −18x^2e^(2x) by undetermined coefficients is y = (Ax^3 + Bx^2)e^(2x) + Cx^2e^(2x) = (-9x^2)e^(2x)

Express the deaths per capita in Scientific Notation.
Express the deaths per capita as a per 100,000 value and use this value in a sentence.

Answers

Answer:  

To express the deaths per capita as a decimal, we can divide the number of new construction accidents (deaths) by the population:

4172/11300000 = 0.00037

Rounded to 6 decimal places, the deaths per capita as a decimal is 0.00037

To express the deaths per capita in scientific notation, we can use the decimal value found above and convert it to scientific notation:

3.7 x 10^-4

To express the deaths per capita as a per 100,000 value, we can multiply the decimal value by 100,000:

0.00037 * 100,000 = 37

So the deaths per capita are 37 deaths per 100,000 people.

One solution of the following system is:

A. (–6, 0)

What is the solution for the system?

The above mathematical expression requires that we use the substitution formula to obtain the correct value.

2y - 2x = 12     ... 1

x² + y² = 36     ... 2

For equation 1

2y = 12 + 2x

          2

y = 6 + x           ... 3

Now we substitute equation 3 in equation 2

x² + (6 + x)² = 36

= x² + 36 + 12x + x² = 36

2x² + 12x = 36 -36

2x² + 12x = 0

2x (x + 6) = 0

x = 0, -6

When we substitute x for 0 in the third equation, we will have

y = 6 + 0 = 6

If we substitute x to be -6 in the third equation, we will arrive at

y = 0.

Therefore, the two solutions that can be obtained are (0,6) and (-6,0) as seen in the first option.

Answers

Answer:

14z + 12x is not equivalent to any of the others

2 + (7z + 6x) is not equivalent to any of the others

2(7z + 6x) is equivalent to 14z + 12x

9x + 3(4z + x) + 2z is not equivalent to any of the others

Step-by-step explanation:

14z + 12x is equivalent to itself

2 + (7z + 6x) is equivalent to (7z + 6x) + 2

2(7z + 6x) is equivalent to 14z + 12x

9x + 3(4z + x) + 2z is equivalent to itself.

A teacher gave her students two tests. If 45% of the students passed both tests and 60% passed the first test. What is the probability that a student who passed the first test also passed the second?

Answers

Answer: We can use the concept of conditional probability to find the probability that a student who passed the first test also passed the second. Conditional probability is the probability of an event occurring given that another event has already occurred.

The probability that a student who passed the first test also passed the second is the probability of both events occurring (passing both tests) divided by the probability of the first event occurring (passing the first test).

We can use the information provided to calculate this probability:

Probability of passing both tests = 0.45 (45%)

Probability of passing the first test = 0.60 (60%)

Probability of passing both tests given that the student passed the first test = (Probability of passing both tests) / (Probability of passing the first test) = 0.45 / 0.60 = 0.75

So the probability that a student who passed the first test also passed the second is 0.75 or 75%.

It means, if we know that a student passed the first test, there's a 75% chance that the student also passed the second test.
