The width of the new rectangular field would be 0 meters, which means it would essentially be a line segment.

To find the length and width of another rectangular field that has the same perimeter but a larger area, we can use the following steps:

1. Calculate the perimeter of the given rectangular field:

  Perimeter = 2 * (Length + Width)

            = 2 * (120 meters + 80 meters)

            = 2 * 200 meters

            = 400 meters

2. Divide the perimeter by 2 to find the equal sides of the new rectangular field. Since the perimeter is divided equally into two sides, each side would be half of the perimeter length:

  Side length = Perimeter / 2

             = 400 meters / 2

             = 200 meters

3. Now, we have the side length of the new rectangular field. However, we need to determine the length and width that would yield a larger area. One way to achieve this is to make one side longer and the other side shorter.

4. Let's assume the length of the new rectangular field is 200 meters. Since both sides have the same length, the width can be calculated using the formula for the perimeter:

  Width = Perimeter / 2 - Length

        = 400 meters / 2 - 200 meters

        = 200 meters - 200 meters

        = 0 meters

5. Therefore, the width of the new rectangular field would be 0 meters, which means it would essentially be a line segment. However, note that the question asks for a rectangular field with a larger area. Since the width cannot be zero, we can conclude that it is not possible to have a rectangular field with the same perimeter but a larger area than the given field.

In summary, it is not possible to find another rectangular field with the same perimeter but a larger area than the rectangular field with dimensions 80 meters wide and 120 meters long.

Answer:

U and Jeno and Jaemin

Step-by-step explanation:

the vectors u = [1, 0], v = [0, 1], and w = [1, 1] satisfy the conditions where {u, v, w} is linearly dependent, and each pair {u, v}, {u, w}, and {v, w} is linearly independent.

To find three vectors u, v, w ∈ R² such that {u, v, w} is linearly dependent while each pair {u, v}, {u, w}, and {v, w} is linearly independent, we can choose the vectors carefully. Let's consider the following vectors:

u = [1, 0]

v = [0, 1]

w = [1, 1]

To justify our answer, we need to show that {u, v, w} is linearly dependent and each pair {u, v}, {u, w}, and {v, w} is linearly independent.

First, we can see that u and v are standard basis vectors in R², and they are linearly independent since no scalar multiples of u and v can result in the zero vector.

Next, we observe that u + v = w, meaning that w can be expressed as a linear combination of u and v. Therefore, {u, v, w} is linearly dependent.

Finally, we check the remaining pairs: {u, w} and {v, w}. In both cases, we can observe that the two vectors are not scalar multiples of each other and cannot be expressed as linear combinations of each other. Hence, {u, w} and {v, w} are linearly independent.

In summary, the vectors u = [1, 0], v = [0, 1], and w = [1, 1] satisfy the conditions where {u, v, w} is linearly dependent, and each pair {u, v}, {u, w}, and {v, w} is linearly independent.

Answer:  B.   5/13

This is the same as writing \(\frac{5}{13}\)

==========================================================

Reason:

We have two given sides of this right triangle. Use the pythagorean theorem to find the missing side.

a = 5 and b = 12 are the two known legs; c is the unknown hypotenuse

\(a^2+b^2 = c^2\\\\c = \sqrt{a^2+b^2}\\\\c = \sqrt{5^2+12^2}\\\\c = \sqrt{25+144}\\\\c = \sqrt{169}\\\\c = 13\\\\\)

The hypotenuse is exactly 13 units long. This is a 5-12-13 right triangle.

Now we can compute sine of theta

\(\sin(\text{angle}) = \frac{\text{opposite}}{\text{hypotenuse}}\\\\\sin(\theta) = \frac{5}{13}\\\\\)

This points us to choice B as the final answer.

The system is underdamped because ζ < 1, which means that the system will oscillate about the equilibrium point, but with gradually decreasing amplitude.

Given the expression of motion of spring-mass system

u(t)=5e^−3tcos(2t)+12e^−3tsin(2t).

To determine whether the system is underdamped, overdamped, or critically damped, we need to find out the damping ratio first. We can obtain the damping ratio by using the following expression-

ζ= (b/2m)

where b = damping constant

m = mass

Next, we need to find out the natural frequency of the system, ωn given by:

ωn = sqrt(k/m)

Here, k is the spring constant. The motion of the system is described as

u(t)=5e^−3tcos(2t)+12e^−3tsin(2t)

We can identify a pattern in the motion of the system as

u(t) = e^−3t (a cos(2t) + b sin(2t))

= e^−3tA cos (2t - φ)

(by the identity a cos(x) + b sin(x) = A cos(x - φ))

where A^2 = a^2 + b^2, and

tan(φ) = b/a

So, we have

A^2 = 5^2 + 12^2

= 169

and

tan φ = 12/5.

=> φ = 67.38 degrees

Now we can substitute the values of b and m to find the value of damping ratio ζ

ζ= (b/2m)

= φ

= tan^-1 (12/5)

Thus the value of damping ratio is 0.859. Now we can use the following conditions to determine whether the system is overdamped, critically damped, or underdamped:

If ζ < 1, the system is underdamped

If ζ = 1, the system is critically damped

If ζ > 1, the system is overdamped

Here, ζ = 0.859, which is less than 1. Therefore, the system is underdamped.

Thus, the system is underdamped because ζ < 1, which means that the system will oscillate about the equilibrium point, but with gradually decreasing amplitude.

Step-by-step explanation:

The formula is incorrect. V = 4πr³/3

Radius r = 10/2 = 5 cm

V = 4πr³/3 ≈ 4×3.14×5³/3 = 523⅓ cm³

The volume of the sphere is 523.3 cm³ if the diameter of the sphere is 10 cm option (B) is correct.

It is defined as three-dimensional geometry when half-circle two-dimensional geometry is revolved around the diameter of the sphere that will form.

We have the diameter of the sphere shown in the picture,

Let's denote the diameter of the sphere as D then,

D = 10 cm

the radius r will be half the diameter.

r = 10/2 ⇒5 cm

The formula for finding the volume of the sphere is given:

\(\rm V = \frac{4}{3} \pi r^3\\\\\rm V = \frac{4}{3} \pi 5^3\)  (r = 5 cm)

\(\rm V =\frac{4}{3} \pi 75\)

V = 166.66π

V = 166.66×3.14      (π = 3.14)

V = 523.31 cm³

Answer:

The distributive property

Step-by-step explanation:

When you have a number on the outside of a set of parenthesis, you can remove the parenthesis by multiplying the term on the outside by each of the terms on the inside. This is known as the distributive property.

E(X) = 1.88.  E(X^2) = 11.12. E((3X + 2)^2) = 126.64. To find E(X) and E(X^2), we will use the provided probability distribution for the random variable X.

E(X) is the expected value of X and can be calculated by multiplying each value of X by its corresponding probability and summing them up. Let's perform this calculation:

E(X) = (-2 * 0.18) + (4 * 0.38) + (6 * 0.12)

= -0.36 + 1.52 + 0.72

= 1.88

Therefore, E(X) = 1.88.

E(X^2) is the expected value of X^2 and can be calculated by multiplying each value of X squared by its corresponding probability and summing them up. Let's perform this calculation:

E(X^2) = ((-2)^2 * 0.18) + (4^2 * 0.38) + (6^2 * 0.12)

= (4 * 0.18) + (16 * 0.38) + (36 * 0.12)

= 0.72 + 6.08 + 4.32

= 11.12

Therefore, E(X^2) = 11.12.

Now, let's evaluate E((3X + 2)^2) using the values of E(X) and E(X^2) obtained in the previous step.

E((3X + 2)^2) = E(9X^2 + 12X + 4)

= 9E(X^2) + 12E(X) + 4

Substituting the values of E(X^2) = 11.12 and E(X) = 1.88:

E((3X + 2)^2) = 9 * 11.12 + 12 * 1.88 + 4

= 100.08 + 22.56 + 4

= 126.64

Therefore, E((3X + 2)^2) = 126.64.

The area under the normal curve between the 20th and 70th percentiles is then calculated as Area = CDF(z₂) - CDF(z₁)

To find the area under the normal curve between the 20th and 70th percentiles, we need to determine the corresponding z-scores for these percentiles and then calculate the area between these z-scores.

The normal distribution is characterized by its mean (μ) and standard deviation (σ). In order to calculate the z-scores, we need to standardize the values using the formula:

z = (x - μ) / σ

where x is the value, μ is the mean, and σ is the standard deviation.

First, let's find the z-score corresponding to the 20th percentile. Since the normal distribution is symmetrical, the 20th percentile is the same as the lower tail area of 0.20. We can use a standard normal distribution table or statistical software to find the z-score associated with this area.

Let's assume that the z-score corresponding to the 20th percentile is z₁.

Next, we find the z-score corresponding to the 70th percentile. Similarly, the 70th percentile is the same as the lower tail area of 0.70. Let's assume that the z-score corresponding to the 70th percentile is z₂.

Once we have the z-scores, we can calculate the area between these z-scores using the cumulative distribution function (CDF) of the standard normal distribution. The CDF gives us the area under the curve up to a particular z-score.

The area under the normal curve between the 20th and 70th percentiles is then calculated as:

Area = CDF(z₂) - CDF(z₁)

where CDF(z) is the cumulative distribution function evaluated at z.

It is important to note that the CDF values can be obtained from standard normal distribution tables or by using statistical software.

In summary, to find the area under the normal curve between the 20th and 70th percentiles, we follow these steps:

Determine the z-score corresponding to the 20th percentile (z₁) and the z-score corresponding to the 70th percentile (z₂).

Calculate the area using the formula: Area = CDF(z₂) - CDF(z₁), where CDF(z) is the cumulative distribution function of the standard normal distribution evaluated at z.

By performing these calculations, we can determine the area under the normal curve between the specified percentiles.

Transmittivity = I_transmitted / (I_reflected + I_transmitted) & Reflectivity = I_reflected / (I_reflected + I_transmitted)

Hi! To derive the expressions for intensity transmittivity and reflectivity given in equations (10.29) and (10.30), respectively, follow these steps:

1. Define the terms:
  - Transmittivity (T): The fraction of incident light transmitted through a medium.
  - Reflectivity (R): The fraction of incident light reflected by a medium.
  - Intensity (I): The power per unit area of light.

2. Consider a light wave incident on a medium with intensities I_incident, I_reflected, and I_transmitted.

3. Based on the conservation of energy, the sum of the reflected and transmitted intensities should equal the incident intensity:
  I_incident = I_reflected + I_transmitted

4. Define the transmittivity and reflectivity expressions:
  - Transmittivity (T) = I_transmitted / I_incident
  - Reflectivity (R) = I_reflected / I_incident

5. Substitute the intensity values into the expressions from step 4:
  - T = I_transmitted / (I_reflected + I_transmitted)
  - R = I_reflected / (I_reflected + I_transmitted)

6. Rearrange the equations to isolate I_reflected and I_transmitted:
  - I_transmitted = T * (I_reflected + I_transmitted)
  - I_reflected = R * (I_reflected + I_transmitted)

These are the expressions for intensity transmittivity (Equation 10.29) and reflectivity (Equation 10.30) based on the given information. Note that these expressions may vary depending on the specific context or system being analyzed.

Sum of angles drawn along a straight line = 180°:

The angle drawn in pink : 180° - 112° = 68°

The angle drawn in green: 180° - 66° = 114°

The angle drawn in yellowish orange: 180° - 23° = 157°

The angle marked in purple: 180° - 102° = 78°

The figure drawn in the center is a 5-sided irregular pentagon

∴ Sum of interior angles in a 5-sided polygon = (n - 2) ×180°

                                                                            = (5 - 2) × 180°

                                                                            = 540°

The four angles calculated above will assist in calculating the fifth remaining angle of the pentagon (which is marked in light blue):

   68° + 114° + 78° + 157° + angle in light blue = 540°

Angle in light blue = 540° - 68° - 114° - 78° - 157°

                               = 123°

Sum of angles drawn along a straight line = 180°:

Angle marked in dark blue = 180° - 123°

                                                = 57°

944 - 5x = 1180 - 9x

Notice what is being said. You start with 944 gallons and take off 5 per week

You also start with 1180 gallons and take on 9 per week.

You want to know when the two are equal. The second tank is larger, but it leaks more. That's what's going to bring about equality.

Add 9x to both sides

944 - 5x + 9x = 1180

944 + 4x = 1180                

Subtract 944 from both sides.

4x = 1180 - 944

4x = 236      

Divide by 4

x = 236/4

x = 59 weeks
