Answer:

In geometry, the tangent line (or simply tangent) to a plane curve at a given point is the straight line that "just touches" the curve at that point. Leibniz defined it as the line through a pair of infinitely close points on the curve. ... The word "tangent" comes from the Latin tangere, "to touch".

Step-by-step explanation:

A straight line touching a curve at a single point without crossing it there is tangent.

Predatory pricing. Predatory pricing occurs when a dominant firm intentionally sets its prices below the cost of production or below its competitors' prices in order to eliminate competition and deter new entrants into the market.

In this scenario, Firm A, the monopolist, engages in predatory pricing by reducing its prices in response to the entry of Firm B into the market. The aim is to make it financially difficult for Firm B to survive and eventually force it out of the market. By lowering its prices, Firm A hopes to attract customers away from Firm B and regain its monopoly power.

Predatory pricing is considered an anti-competitive practice and is often illegal in many jurisdictions. It can harm competition, limit consumer choice, and lead to higher prices in the long run. Regulatory bodies and competition authorities closely monitor such practices and may take legal action against firms found engaging in predatory pricing.

Overall, predatory pricing is a strategy employed by dominant firms to protect or strengthen their market position by driving out competitors. However, it is important for regulators to enforce antitrust laws to ensure fair competition and protect the interests of consumers and smaller market players.

Step-by-step explanation:

Since the joint pdf \(\(f(x,y)\)\) cannot be expressed as the product of the marginal pdfs \(\(f_X(x)\) and \(f_Y(y)\),\)we conclude that x and y are not independent.

What is the determination of independence?

The determination of independence refers to the process of assessing whether two or more random variables are statistically independent of each other. Independence is a fundamental concept in probability theory and statistics.

When two random variables are independent, their outcomes or events do not influence each other. In other words, the occurrence or value of one variable provides no information about the occurrence or value of the other variable.

To determine whether x and y are independent, we need to check if the joint probability density function (pdf) can be expressed as the product of the marginal pdfs.

The joint pdf of \(x\) and \(y\) is given as:

\(\[ f(x,y) = xy, \quad 0 < x < 1, \quad 0 < y < 1 \]\)

To determine the marginal pdfs, we integrate the joint pdf over the range of the other variable. Let's start with the marginal pdf of x

\(\[ f_X(x) = \int_{0}^{1} f(x,y) \, dy \]\[ = \int_{0}^{1} xy \, dy \]\[ = x \int_{0}^{1} y \, dy \]\[ = x \left[\frac{y^2}{2}\right]_{0}^{1} \]\[ = x \left(\frac{1}{2} - 0\right) \]\[ = \frac{x}{2} \]\)

Similarly, we can calculate the marginal pdf of y:

\(\[ f_Y(y) = \int_{0}^{1} f(x,y) \, dx \]\[ = \int_{0}^{1} xy \, dx \]\[ = y \int_{0}^{1} x \, dx \]\[ = y \left[\frac{x^2}{2}\right]_{0}^{1} \]\[ = y \left(\frac{1}{2} - 0\right) \]\[ = \frac{y}{2} \]\)

Since the joint pdf \(\(f(x,y)\)\) cannot be expressed as the product of the marginal pdfs\(\(f_X(x)\\)) and \(\(f_Y(y)\)\), we conclude that x and y are not independent.

Answer:

the length of the other leg is 4sqrt(24) yards. This can also be simplified as 8sqrt(6) yards.

Step-by-step explanation:

Let's use the Pythagorean theorem, which states that in a right triangle, the square of the length of the hypotenuse (the longest side) is equal to the sum of the squares of the lengths of the legs (the other two sides).

In this problem, one leg has a length of 13 yards, and the hypotenuse has a length of 23 yards. Let's call the length of the other leg x.

Using the Pythagorean theorem, we get:

23^2 = 13^2 + x^2

Simplifying and solving for x, we get:

x^2 = 23^2 - 13^2

x^2 = 384

x = sqrt(384)

x = sqrt(16 * 24)

x = 4sqrt(24)

Therefore, the length of the other leg is 4sqrt(24) yards. This can also be simplified as 8sqrt(6) yards.

The approximate volume of the given cylindrical container which has 3 balls is 63.62 in³, under the condition that tennis ball has a diameter of about 3 inches. Then, the required answer is 64 in³ which is Option A.

Now

The volume of a tennis ball is approximately

\(4/3 * \pi * (diameter/2)^{3}\)

=\(4/3 * \pi * (1.5)^{3}\)

= 14.137 in³.

Therefore, 3 balls are present in the container.

The diameter of a tennis ball = 3 inches,

Radius = 1.5 inches.

The height of the cylindrical container can be evaluated by multiplying the diameter of a tennis ball by three

Now,  three tennis balls are kept on top of each other.

Then, the height of the cylindrical container

3 × 3 = 9 inches.

The radius = 1.5 inches.

The volume of a cylinder = \(V = \pi * r^2 * h\)

Here,

 V = volume,

r = radius

h = height.

Staging the values

\(V = \pi * (1.5)^{2} * 9\)

= 63.62 in³.

From a point 100m from a building the angles of elevation to the top and the bottom of a flagpole atop the building are 54.5 degrees and 51.8 degrees. Therefore, the height of the flagpole is 125.6m.

we can use the trigonometric ratios of Sine, Cosine, and Tangent.

First, we need to draw a right triangle with the given information.

The triangle will have two sides:

the 100m side and the side to the flagpole. We can use the angle of elevation of 54.5 degrees to calculate the side of the triangle opposite the flagpole.

To do this, we use the Tangent ratio and solve for the side opposite the flagpole (the height of the flagpole):

Tangent(54.5) = Height/100

Height = 100*Tangent(54.5)

Height = 100*1.256

Answer: The y-intercept is -12

The x-intercept is 8

Step-by-step explanation: Factor out 3

Divide all by 3 to simplify.

9x - 6y = 72 is equivalent to

3x - 2y = 24

At this point, you can substitute 0 for x and solve for y

3(0) -2y = 24. -2y/-2 = 24/-2

y = -12

And substitute 0 for y and solve for x.

3x -2(0) = 24. 3x/3 = 24/3

x = 8

OR Change to slope intercept form:

y = mx + b. b is the y intercept.

-2y = -3x + 24. Solve for y.

Divide all by-2

y = 3x/2 - 12.

The y-intercept is -12

To find the x-intercept, substitute 0 for y and solve for x.

0 = 3x/2 -12 Add 12 to both sides.

12 = 3x/2. Multiply both sides by 2/3

Domain: For sales, x > 0 (positive values); for returns, x < 0 (negative values).

Range: F(x) ≥ 0 (non-negative values).

The given function is defined as follows:

For x > 0 (sale): F(x) = |x| * 0.015

For x < 0 (return): F(x) = |x| * 0.005

The domain of the function is the set of all possible input values, which in this case is all real numbers. However, due to the specific conditions mentioned, the domain is restricted to positive values of x for the "sale" scenario (x > 0) and negative values of x for the "return" scenario (x < 0).

Therefore, the domain of the function F(x) is:

For x > 0 (sale): x ∈ (0, +∞)

For x < 0 (return): x ∈ (-∞, 0)

The range of the function is the set of all possible output values. Since the function involves taking the absolute value of x and multiplying it by a constant, the range will always be non-negative. In other words, the range of the function F(x) is:

For x > 0 (sale): F(x) ∈ [0, +∞)

For x < 0 (return): F(x) ∈ [0, +∞)

In conclusion, the domain of the function F(x) is x ∈ (0, +∞) for sales and x ∈ (-∞, 0) for returns, while the range is F(x) ∈ [0, +∞) for both scenarios.

The probability that the waiter will earn less than $450 in tips when he waits on 40 parties is 0.2364. This means that there is a 23.64% chance that the waiter will make less than $450 in tips.

The probability that the waiter will earn less than $450 in tips when he waits on 40 parties can be calculated using the binomial distribution. The binomial distribution is used to calculate the probability of success in a series of independent events. In this case, the probability of success is the probability that the waiter will earn less than $450 in tips.The number of independent events, or trials, is 40, since the waiter will serve 40 parties. The probability of success for each trial is the expected average tip amount divided by the total amount of tips the waiter is trying to earn. The expected average tip amount is $11, and the total amount of tips the waiter is trying to earn is $450, so the probability of success for each trial is 0.024.Using the binomial distribution formula, the probability that the waiter will earn less than $450 in tips when he waits on 40 parties is 0.2364. This means that there is a 23.64% chance that the waiter will make less than $450 in tips.

\(p = (n! / (x! * (n-x)!) * p^x * (1-p)^(n-x))\)

where

n = 40 (number of parties)

x = 450 (desired tip amount)

p = 0.1 (probability of earning a tip of $10)

p = (40! / (450! * (40-450)!) * 0.1^450 * (1-0.1)^(40-450))

I. f(x) and g(x) have continuous first and second derivatives everywhere, so by the mean value theorem, there exists a point c in the interval (a, b) such that f'(c) = (f(b) - f(a)) / (b - a) and g'(c) = (g(b) - g(a)) / (b - a). Since f(x) < g(x) for all x, we have f(b) - f(a) < g(b) - g(a), so f'(c) < g'(c), and thus, f'(x) < g'(x) for all x.

II. f(x) and g(x) have continuous first and second derivatives everywhere, so by the mean value theorem, there exists a point c in the interval (a, b) such that f''(c) = (f'(b) - f'(a)) / (b - a) and g''(c) = (g'(b) - g'(a)) / (b - a). Since f'(x) < g'(x) for all x, we have f'(b) - f'(a) < g'(b) - g'(a), so f''(c) < g''(c), and thus, f''(x) < g''(x) for all x.
