Calculating 3A and 2B first, then deducting 2B frοm 3A, is required tο find 3A - 2B.
Calculating 3A:
[tex]3A = 3 * \left[\begin{array}{ccc}2 & -1 & 3\1 & 1 & -3 & -1\end{array}\right]= \left[\begin{array}{ccc}6 & -3 & 9\3 & 3 & -9 & -3\end{array}\right][/tex]
Calculating 2B:
[tex]2B = 2 * \left[\begin{array}{ccc}-2 & 1 & 3 & -1 & -2 & -2 \end{array}\right]= \left[\begin{array}{ccc}-4 & 2 & 6 & -2 & -4 & -4\end{array}\right][/tex]
Nοw, we can find 3A - 2B by subtracting 2B frοm 3A:
[tex]3A - 2B = \left[\begin{array}{ccc}6 & -3 & 9 &3& -9 & -3\end{array}\right] - \left[\begin{array}{ccc}-4 & 2 & 6 &-2 & -4 & -4\end{array}\right]= \left[\begin{array}{ccc}10 & -5 & 3 &5 & -5 & 1\end{array}\right][/tex]

Sweetness is an example of empirical intuition, according to Kant.
True or False
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.
What is empirical intuition?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.

For what to go through a phase change, it’s temperature must be greater than or equal to 212°F or less than or equal to 32°F. If a glass of water is currently at 75°F, what temperature changes will produce a phase change?
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).
What is the temperature range for a stage change in water?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.

Create a rational inequality for which −1 < ≤ 2 is the solution.
Thus, the rational inequality formed for the given solution is found as:
x - 3 ≤ 0
Explain about the rational inequality:A rational inequality is a specific type of statistical inequality statement that typically has a ratio of two polynomials (commonly known as a "rational expression") on the left side and a zero on the right.
A rational expression seems to be a ratio of two polynomials, and a rational inequality is just an inequality that contains a rational expression. To put it another way, a rational expression has the form R(x) / Q(x), when R(x) and Q(x) represent polynomials and Q(x) is not zero. A rational expression appears on the left side of a rational inequality's general form, and a zero appears on the right.Given expression is:
−1 + x ≤ 2

A rectangle has side lengths (4x-5) and (3x+6). Write a linear expression in simplest form to represent the perimeter. Find perimeter if the value of x=12
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.

An image of a coordinate plane shows a dashed horizontal line. The line crosses the y-axis at (0, 2) and passes through the points (2, 2) and (negative 2, 2). The area above the line is shaded.
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.

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).

The volume of a rectangular prism is 6,142.5 cm3. If the height is 16.25 cm and the length is 28 cm, what is the value of the width?
13.125 cm
13.25 cm
13.5 cm
13.75 cm
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.

Gildong decided to save 20,000 won a week. He saved for 15 weeks and then for 15 weeks he spent 20,000 won a week on eating Maratang. Write an absolute-value function to represent the amount of money Gildong had in savings.
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.
