[tex]f'(x) = 21cos(3x)/(1+49sin²(3x)).[/tex] and the outcome is f'(x) = 21cos(3x)/(1+49sin2(3x)). This is the derivative of the function f(x) with respect to x.

We apply the chain rule and the formula for the derivative of the inverse tangent function to determine the derivative of f(x). We first determine that the function contained within the inverse tangent is 7sin (3x). Thus, by differentiating f(x) with respect to x using the derivative of the inverse tangent function, we are able to get an equation in terms of cos(3x) and sin (3x). Trigonometric identities are used to simplify this formula, and the result is[tex]f'(x) = 21cos(3x)/(1+49sin2(3x))[/tex]. This is the derivative of the function f(x) with respect to x.

Answer:

P = 14x + 2

if x=12, P = 170

Step-by-step explanation:

The perimeter is the distance around the outside of the shape.

The rectangle has four sides. Two long sides and two short sides.

We add up all four sides.

P = 4x-5+3x+6+4x-5+3x+6

combine like terms.

P = 14x + 2 this is the equation in simplest form.

If x = 12, we can calculate the perimeter.

P = 14(12) + 2

P = 168 + 2

P = 170

The perimeter would be 170.

Answer:

False. Kant's notion of empirical intuition refers to the immediate awareness of particular objects or experiences, which he believed was necessary for gaining knowledge of the world. However, sweetness is not an example of empirical intuition as it is a subjective experience that cannot be directly observed or measured.

It is false that sweetness is an example of empirical intuition, according to Kant.

Immanuel Kant introduced the concept of empirical intuition, which refers to the mind's ability to organise and structure sensory experience. It enables us to perceive objects and events in our surroundings and form opinions about them. However, it has nothing to do with sweetness.

Kant defines empirical intuition as sensory information received through our senses, such as colours, shapes, and sounds.

Empirical intuition, according to Kant, refers to the a priori knowledge we have about space and time that shapes our experience of the world.

It excludes abstract concepts like sweetness, which are derived from our perception and interpretation of sensory data.

Thus, the given statement "Sweetness is an example of empirical intuition, according to Kant" is false.

Heating the water to a temperature of 212°F or higher, which will cause it to boil and transform from a liquid to a gas (water vapor).

Cooling the water down to a temperature of 32°F or lower, which will cause it to freeze and transform from a liquid to a solid (ice).

The temperature range for a stage change in water is either more noteworthy than or equivalent to 212°F or not exactly or equivalent to 32°F, which compares to the bubbling and edges of freezing over of water, separately.

The water is still in its liquid state at 75°F, but it will change phases if it reaches 212°F or is cooled to 32°F or lower.

Therefore, the temperature changes that will produce a phase change in a glass of water at 75°F are:

Heating the water to a temperature of 212°F or higher, which will cause it to boil and transform from a liquid to a gas (water vapor).

Cooling the water down to a temperature of 32°F or lower, which will cause it to freeze and transform from a liquid to a solid (ice).

It is important to note that the temperature of the water will not change during the phase change until the entire change is complete. To put it another way, when water is boiling, it will remain at 212°F until all of the liquid has evaporated, and when it is frozen, it will remain at 32°F until all of the liquid has frozen solid.

Correct question:

Create a rational inequality for which −1 + x ≤ 2 is the solution.

Answer:

To determine if (0,3) is a solution to y>2, we need to check if y is greater than 2 when x=0 and y=3. Since 3 is greater than 2, the point (0,3) satisfies the inequality y>2.

To graph the inequality y>2, we need to shade the region above the horizontal line y=2. The line y=2 is a solid line since it includes the points where y=2, but the region above the line is shaded with a dashed line since it does not include the points where y=2.

Here is a description of the graph:

Draw a horizontal line passing through the point (0,2).

Shade the region above the line with a dashed line.

The graph visually represents all the points that satisfy the inequality y>2. Since the point (0,3) is above the line, it is part of the shaded region and satisfies the inequality.

Answer:

A. 13.125cm

Step-by-step explanation:

To solve for the width of the rectangular prism, we can use the formula for the volume of a rectangular prism, which is:

volume = length x width x height

We are given that the volume is 6,142.5 cm^3, the height is 16.25 cm, and the length is 28 cm. Let's substitute these values into the formula and solve for the width:

6,142.5 cm^3 = 28 cm x width x 16.25 cm

Dividing both sides by (28 cm x 16.25 cm), we get:

width = 6,142.5 cm^3 / (28 cm x 16.25 cm)

= 13.125 cm

Therefore, the width of the rectangular prism is 13.125 cm. So, the correct answer is A) 13.125 cm.

There are approximately 78 trees on each acre of land when the trees are spread out evenly.

To find the number of trees on each acre of land mathematically, we can use the formula for average or mean.

The average number of trees per acre can be found by dividing the total number of trees by the total number of acres. In this case, we have 2808 trees and 36 acres:

Average number of trees per acre = Total number of trees / Total number of acres

Average number of trees per acre = 2808 / 36

Average number of trees per acre = 78

Therefore, there are approximately 78 trees on each acre of land when the trees are spread out evenly.

This means that if the land is divided into 36 equal sections, each section will have approximately 78 trees.

It has uses in physics, economics, computer science, statistics, and other disciplines.

given

Let A represent the scenario in which the first student chosen is under 62 inches, and B represent the scenario in which the second student chosen is under 62 inches as well.

Since there are two shorter kids out of a total of five students, the likelihood of choosing one on the first try is 2/5.

Given that the first student was shorter, the likelihood of choosing another shorter student on the second try is 1/4 because there would only be 1 shorter student left out of the other 4 students.

Thus, the likelihood of picking two consecutive students who are shorter

The formula for P(A and B) is P(A) P(B|A) = (2/5) (1/4) = 1/10.

Answer:

Step-by-step explanation:

Let's start by defining a coordinate system where the horizontal axis represents the number of weeks that Gildong has been saving (and spending), and the vertical axis represents the amount of money he has in savings.

During the first 15 weeks, Gildong saved 20,000 won per week, so his savings increased linearly from week 0 to week 15. We can represent this with the equation:

y = 20,000x

where x is the number of weeks since the beginning (x = 0 corresponds to the start of the saving period) and y is the amount of money Gildong has saved after x weeks.

During the next 15 weeks, Gildong spent 20,000 won per week on eating Maratang, so his savings decreased linearly from week 15 to week 30. We can represent this with the equation:

y = -20,000(x - 15) + 20,000(15)

where x is the number of weeks since the beginning (x = 15 corresponds to the start of the spending period) and y is the amount of money Gildong has saved after x weeks.

To represent the total amount of money Gildong had in savings at any given time, we can combine the two equations above using an absolute value:

y = |20,000x| - 20,000(x - 15)

where x is the number of weeks since the beginning, and y is the amount of money Gildong has in savings after x weeks.

This function represents the absolute value of the difference between the amount of money Gildong has saved and the amount of money he has spent on Maratang, taking into account the fact that his savings increased linearly during the first 15 weeks and decreased linearly during the next 15 weeks.

The measure of the angle in the given circle which pass through 2 parts out of 5 is 144°.

All points in a plane that are at a specific distance from a specific point, the center, form a circle.

In other words, it is the curve that a moving point in a plane draws to keep its distance from a specific point constant.

The radius of a circle is the separation between any point on the circle and its center.

The radius must typically be a positive integer. A circle, specifically, is a straightforward closed curve that separates the plane into its inner and exterior.

In common usage, the word "circular" can be used to describe both the figure's edge and its entirety, including its interior.

So, we know that:

The angle of the center of the circle is 360°.

We also know that in the given situation, the circle is divided into 5 parts.

Then,

= 360/5

= 72

Now,

The measure of 2 parts:

72 + 72 = 144

Therefore, the measure of the angle in the given circle which pass through 2 parts out of 5 is 144°.
