Answer:

The bottom right

Step-by-step explanation:

A technical definition of a function is a relation from a set of inputs to a set of possible outputs where each input is related to exactly one output. Meaning no x values repeat. An easy way to test this is if you draw a vertical line anywhere it will only intersect with the function once.

This is because it is not possible to pass a vertical line through more than one point on the curve.

For the top right and bottom left corners, we can pass a vertical line through more than one point on the curve, so they fail the vertical line test. We can rule these choices out.

Any vertical line itself is not a function. A function is only possible if any x input leads to exactly one y output.

To find a probability you take the specific parameters divided by the entire set of possibilities.

For example, the specific parameter here is that the drink must be a medium, (no matter the temperature). So, we would add 48 and 12 to get 60.

And we know that the total number of orders is 100.

So, we should divide 60 by 100, and we get 60%.

Step-by-step explanation:

12²=a²+9²

144=a²+81

a²=144-81

a²=63

a=√63

a=7.94

The forward Fourier Transform formula for a signal is X(jω) = F{x(t)}. The inverse Fourier Transform formula is x(t) = F^(-1){X(jω)}. The two formulas are related by the Fourier Transform property called duality or symmetry.

1. The forward Fourier Transform formula is given by:

  X(jω) = ∫[x(t) * e^(-jωt)] dt

  This formula calculates the complex spectrum X(jω) of a signal x(t) by integrating the product of the signal and a complex exponential function.

2. The inverse Fourier Transform formula is given by:

  x(t) = (1/2π) ∫[X(jω) * e^(jωt)] dω

  This formula reconstructs the original signal x(t) from its complex spectrum X(jω) by integrating the product of the spectrum and a complex exponential function.

  The similarity between these two formulas is known as the Fourier Transform property of duality or symmetry. It states that the Fourier Transform pair (X(jω), x(t)) has a symmetric relationship in the frequency and time domains. The forward transform calculates the spectrum, while the inverse transform recovers the original signal. The duality property indicates that if the spectrum is known, the inverse transform can reconstruct the original signal, and vice versa.

3. To determine the Fourier Transform of the given signal x(t) = [-1, 1, 0, -1], we apply the defining integral:

  X(jω) = ∫[-1 * e^(-jωt1) + 1 * e^(-jωt2) + 0 * e^(-jωt3) - 1 * e^(-jωt4)] dt

  Here, t1, t2, t3, t4 represent the respective time instants for each element of the signal.

  Substituting the time values and performing the integration, we can obtain the Fourier Transform of x(t).

Note: Please note that without specific values for t1, t2, t3, and t4, we cannot provide the numerical result of the Fourier Transform for the given signal. The final answer will depend on these time instants.

The solution to this question is  27 units the perimeter of kite OBDE.

The perimeter of a shape is the entire length of the shape's boundary as used in geometry. A form's perimeter can be calculated by adding the lengths of all of its sides and edges. In order to calculate it, linear distances such as centimeters, meters, inches, or feet are used.

Here

This is because 15x15 =225

8x8 = 64

225+64=289 and

the square root of 289 is 17 and that is the diameter of the circle and the hypotenuse of the triangle and since the kite has two congruent sides which are both radii or  can be written as half of a diameter times two would be the same as the length of the diameter which is17+the two bottom sides (which are both 5 and 5 )

So 5+ 5 = 10 and

10 + 17 =27 or the perimeter of the kite.

Therefore ,the perimeter of kite OBDE is 27 units.

The revenue function R(x) is -0.00052x^2 + 6x. The profit function P(x) is -0.00056x^2 + 4x - 600. The derivative of the profit function is -0.00112x + 4. The critical number of the function P(x) is x = 3571. Phonola should produce 3571 discs.

To find the revenue function R(x), we use the given equation p=-0.00052x + 6 and the definition of revenue, R(x) = px. Substituting p, we get R(x) = (-0.00052x + 6)x = -0.00052x^2 + 6x.

To find the profit function P(x), we subtract the cost function C(x) = 600 + 2x - 0.00004x^2 from the revenue function R(x) = -0.00052x^2 + 6x. Hence, P(x) = R(x) - C(x) = (-0.00052x^2 + 6x) - (600 + 2x - 0.00004x^2) = -0.00056x^2 + 4x - 600.

To find the derivative of the profit function, we differentiate P(x) with respect to x, P'(x) = -0.00112x + 4.

To find the critical number of the function P(x), we set P'(x) = 0 and solve for x, -0.00112x + 4 = 0, x = 3571.4. Rounding to the nearest whole number, the critical number is x = 3571.

To maximize its profits, Phonola should produce 3571 discs each month, which corresponds to the critical number we found.

The interval containing the middle-most 48% of sample means is approximately [88.23, 91.77] (using interval notation).

To find the interval containing the middle-most 48% of sample means, we can use the Central Limit Theorem and the properties of the standard normal distribution.

Since the sample size is large (n = 35), we can approximate the distribution of the sample means to be normal with a mean equal to the population mean (μ = 90) and a standard deviation equal to the population standard deviation divided by the square root of the sample size (σ/√n = 20/√35 ≈ 3.38).

To determine the interval containing the middle-most 48% of sample means, we need to find the z-scores that correspond to the lower and upper percentiles. The middle 48% corresponds to the range from the 26th percentile to the 74th percentile (100% - 48% = 52% / 2 = 26%).

Using a standard normal distribution table or a calculator, we can find the z-scores corresponding to these percentiles. The z-score for the 26th percentile is approximately -0.675 and the z-score for the 74th percentile is approximately 0.675.

Now, we can calculate the corresponding values for the sample means using the formula:

Sample Mean = Population Mean + (Z-Score) * (Standard Deviation / √Sample Size)

Lower Bound = 90 + (-0.675) * (20 / √35) ≈ 88.23

Upper Bound = 90 + (0.675) * (20 / √35) ≈ 91.77

Therefore, the interval containing the middle-most 48% of sample means is approximately [88.23, 91.77] (using interval notation).

To approximate the solution and maximize the given objective function we need to find the steepest ascent direction and iteratively update the values of x₁ and x₂ to approach the maximum value of z.

The method of steepest ascent involves finding the direction that leads to the maximum increase in the objective function and updating the values of the decision variables accordingly. In this case, we aim to maximize the objective function z = -(x₁ - 3)² - (x₂ - 2)².

To find the steepest ascent direction, we can take the gradient of the objective function with respect to x₁ and x₂. The gradient represents the direction of the steepest increase in the objective function. In this case, the gradient is given by (∂z/∂x₁, ∂z/∂x₂) = (-2(x₁ - 3), -2(x₂ - 2)).

Starting with initial values for x₁ and x₂, we can update their values iteratively by adding a fraction of the gradient to each variable. The fraction determines the step size or learning rate and should be chosen carefully to ensure convergence to the maximum value of z.

By repeatedly updating the values of x₁ and x₂ in the direction of steepest ascent, we can approach the solution that maximizes the objective function z. The process continues until convergence is achieved or a predefined stopping criterion is met.

Answer:

√3 + 1

Step-by-step explanation:

Step below are self-explanatory

The angle you would observe between the two ends of the meter stick if the pool is Part A empty is 18.92 degrees.

To determine the angle you observe between the two ends of the horizontal meter stick when the pool is empty, you can use the concept of similar triangles. The meter stick is 1.0 meter long and is centered at the bottom of the pool, so each half is 0.5 meters. The pool is 3.0 meters deep and 3.0 meters wide.

To find the angle, you can use the tangent function:

tan(θ) = opposite / adjacent

In this case, the opposite side is the half-length of the meter stick (0.5 meters), and the adjacent side is the depth of the pool (3.0 meters). So,

tan(θ) = 0.5 / 3.0

Now, to find the angle, use the inverse tangent function (arctan):

θ = arctan(0.5 / 3.0)

θ ≈ 9.46 degrees

Since there are two equal angles formed by the meter stick (one on the left and one on the right), the total angle you observe between the two ends of the meter stick would be:

Total angle = 2 * 9.46 ≈ 18.92 degrees

So, when the pool is empty, you observe an angle of approximately 18.92 degrees between the two ends of the horizontal meter stick.

Note: The question is incomplete. The complete question probably is: A horizontal meter stick is centered at the bottom of a 3.0-m-deep, 3.0-m-wide pool. Suppose you place your eye just above the edge of the pool, looking along the direction of the meter stick. What angle do you observe between the two ends of the meter stick if the pool is Part A empty? Express your answer with the appropriate units.
