Main Answer:

The Fourier Transform X(w) for the given cases is as follows:

1. v(t) = 2x(4t-2): X(w) = 1/2 rect(w/4) * e^(-jw/2)

2. v(t) = 2 rect(t): X(w) = 1/2 sinc(w/2)

3. v(t) = cos(2)x(t): X(w) = 1/2 [mrect(w - 2) + mrect(w + 2)]

4. v(t) = 2e^(2i) sinc(t): X(w) = 1/2 [mrect(w + 2) + mrect(w - 2)]

In the given question, we are provided with a set of Fourier Transform pairs. The task is to find the Fourier Transform X(w) for different cases of v(t). Let's analyze each case:

1. For v(t) = 2x(4t-2):

  By applying the time-scaling property of the Fourier Transform, we can express v(t) as 2x(t/4) * e^(-j(2/4)w).

  The Fourier Transform of x(t) = sinc(t) is given as X(w) = rect(w) * e^(-jw/2).

  Using the time-scaling property, the Fourier Transform X(w) for v(t) is obtained as 1/2 rect(w/4) * e^(-jw/2).

2. For v(t) = 2 rect(t):

  The rectangular pulse function rect(t) has a Fourier Transform of sinc(w).

  By scaling the amplitude by a factor of 2, the Fourier Transform X(w) for v(t) is obtained as 1/2 sinc(w/2).

3. For v(t) = cos(2)x(t):

  The Fourier Transform of cos(at) is given by 1/2 [mrect(w - a) + mrect(w + a)] multiplied by the Fourier Transform X(w) of x(t).

  Here, a = 2, and X(w) is sinc(w).

  Therefore, the Fourier Transform X(w) for v(t) is 1/2 [mrect(w - 2) + mrect(w + 2)].

4. For v(t) = 2e^(2i) sinc(t):

  By applying the complex modulation property, we can express v(t) as e^(2i) * 2x(t), where x(t) = sinc(t).

  The Fourier Transform X(w) of x(t) = sinc(t) is given as rect(w).

  Applying the complex modulation property, the Fourier Transform X(w) for v(t) is obtained as 1/2 [mrect(w + 2) + mrect(w - 2)].

The equation that represents h(x) is h(x) = (f(x))(g(x)).

To determine which equation represents h(x), we need to analyze the given table and understand the relationship between the functions f(x), g(x), and h(x).

Since h(x) represents the output values obtained by multiplying f(x) and g(x), we should look for values in the table where h(x) is the product of the corresponding values of f(x) and g(x).

Let's examine the table and compare the values:

x | f(x) | g(x) | h(x)

1 | 3 | 4 | 12

2 | 5 | 2 | 10

3 | 2 | 6 | 12

From the table, we can see that the values in the h(x) column are the products of the corresponding values in the f(x) and g(x) columns. Therefore, the equation that represents h(x) is h(x) = (f(x))(g(x)).

There are nC2 different votes possible, where n is the number of bands on the list and nC2 represents the number of ways to choose 2 bands out of n.

To calculate nC2, we can use the formula for combinations, which is given by n! / (2! * (n-2)!), where ! represents factorial.

Let's say there are m bands on the list. The number of ways to choose 2 bands out of m can be calculated as m! / (2! * (m-2)!). Simplifying this expression further, we get m * (m-1) / 2.

Therefore, the number of different votes possible is m * (m-1) / 2.

In the given scenario, we don't have the specific number of bands on the list, so we cannot provide an exact number of different votes. However, you can calculate it by substituting the appropriate value of m into the formula m * (m-1) / 2.

To find the ratio of blue balloons to the total number of balloons, firstly we need to find the number of blue balloons. Performing addition and subtraction for the same as follows -

Total number of balloons = Number of blue balloons + number of red balloons + number of white balloons

Number of blue balloons = 14 - (3 + 4)

Number of blue balloons = 14 - 7

Number of blue balloons = 7

Ratio = Number of blue balloons to the total number of balloons

Ratio = 7:14

If IQ scores are normally distributed with a mean of 100 and a standard deviation of 15, we can use the normal distribution properties to find the percentage of IQ scores between 85 and 130.

Specifically, we can standardize the scores and use a normal distribution table or calculator to find the area under the curve between the z-scores corresponding to 85 and 130.To find the percentage of IQ scores between 85 and 130, we first need to standardize the scores by subtracting the mean and dividing by the standard deviation. This gives:

z1 = (85 - 100) / 15 = -1.00

z2 = (130 - 100) / 15 = 2.00

We can then use a normal distribution table or calculator to find the area under the curve between these two z-scores. For example, using a standard normal distribution table, we can find that the area to the left of z = -1.00 is 0.1587 and the area to the left of z = 2.00 is 0.9772. Therefore, the area between these two z-scores is:

0.9772 - 0.1587 = 0.8185

This means that approximately 81.85% of IQ scores are between 85 and 130. Alternatively, we can use a normal distribution calculator to find the same result. For example, using an online calculator, we can input the mean (100), standard deviation (15), and the lower and upper limits (85 and 130) and obtain a probability of 0.8185, or 81.85%.

Answer:

324 and 144

Step-by-step explanation:

We require

a₁, a₂, a₃, a₄

where a₂ and a₃ are the required geometric means

The n th term of a geometric sequence is

\(a_{n}\) = a₁\((r)^{n-1}\)

where a₁ is the first term and r the common ratio

Here a₁ = 729 and a₄ = 64, thus

729(r³) = 64 ( divide both sides by 729 )

r³ = \(\frac{64}{729}\) ( take the cube root of both sides )

r = \(\sqrt[3]{\frac{64}{729} }\) = \(\frac{4}{9}\) , then

a₂ = 729 × \(\frac{4}{9}\) = 81 × 4 = 324

a₃ = 324 × \(\frac{4}{9}\) = 36 × 4 = 144

Thus

729, 324, 144, 64

Answer:

The slope of a linear model can be calculated using the formula:

m = Δy / Δx

where:

Δy = change in y (the dependent variable, in this case, total cost)

Δx = change in x (the independent variable, in this case, number of candy bars)

This is essentially the "rise over run" concept from geometry, applied to data points on a graph.

In this case, we can take two points from the table (for instance, the first and last) and calculate the slope.

Let's take the first point (3 candy bars, $6.65) and the last point (25 candy bars, $48.45).

Δy = $48.45 - $6.65 = $41.8

Δx = 25 - 3 = 22

So the slope m would be:

m = Δy / Δx = $41.8 / 22 = $1.9 per candy bar

This suggests that the cost of each candy bar is $1.9 according to this linear model.

Please note that this assumes the relationship between the number of candy bars and the total cost is perfectly linear, which might not be the case in reality.

Answer:

area = 57√3 cm²

Step-by-step explanation:

lower polygon:

14-8 = 6, 6/2 = 3

3 is the base of the lower left triangle

cos 60° = 3/hypotenuse

hypotenuse = 6

height of triangle² = 6² - 3² = 45

height of triangle² = 36 - 9 = 27

height of triangle = √27 = √(9 x 3) = 3√3

area of lower polygon = 1/2(8+14)(3√3) = 33√3 cm²

upper parallelogram:

area = 8(3√3) = 24√3 cm²

total area = 24√3 + 33√3 = 57√3 cm²

m is slope

c is y-intercept

From the graph, we see that:

y-intercept = 15 gallons

Option D is the correct answer.

We have,

We can check whether (-2, 2) is a solution to the system by substituting the values of x and y into both equations and verifying whether they are true.

y - x = -4:

(2) - (-2) = -4

4 = -4

This is false, so (-2, 2) is not a solution to the first equation.

-3x - 2y = -10:

-3(-2) - 2(2) = -10

Answer: The compound interest on a savings account is calculated by multiplying the principal (initial amount deposited) by the interest rate, and then multiplying that result by the number of compounding periods.

In this case, the principal is $925, the interest rate is 5.5%, and the number of compounding periods is 2 (since the interest is compounded semiannually).

To calculate the compound interest, we can use the following formula:

Compound interest = principal * (1 + interest rate/number of compounding periods)^(number of compounding periods * number of years) - principal

Plugging in the values from the problem, we get:

Compound interest = $925 * (1 + 5.5%/2)^(2 * 1) - $925

= $925 * 1.0275^2 - $925

= $925 * 1.056 - $925

= $973.44 - $925

= $48.44

Therefore, the compound interest on Matthew's savings account is $48.44.
