The answer to this problem.

Then use the property of exponents,

→ \( \sf a^cb^c = (ab)^c\)

Let's find the solution,

→ 9b²c²

→ 3²b²c²

→ (3bc)²

Hence, (3bc)² is the answer.

The value of z in the regular nonagon is 15.

A regular polygon is a polygon with congruent sides and equal angles.

If all the polygon sides and interior angles are equal, then they are known as regular polygons.

Therefore, the regular polygon above is a nonagon because it has 9 sides. Therefore, the sum of interior angles of a nonagon is 1260 degrees.

Hence, all the angles of the regular nonagon are congruent.

9 m∠a = 1260 degrees

m∠a = 5z + 65

9(5z + 65) = 1260

45z + 585 = 1260

45z = 1260 - 585

45z = 675

divide both sides by 45

z = 675 / 45

Therefore,

z = 15

Step-by-step explanation:

If you look at the picture, you can see that it is decreasing from hour 3 to hour 4.

This means that from 3 < x < 4, it is decreasing.

Answer:

A) \(\frac{3}{8}\) and 24

Step-by-step explanation:

The coefficients are simply the numerical values that are multiplying the variables.

1) The wavelength of A is equal to 6.98 × \(10^{-8}\)meters

2) The wavelength of B is equal to 3.45 × \(10^{-11}\) meters

Since we know that the wavelength = speed of light / frequency

The speed of light is 3.00 × \(10^8\) meters per second.

For light sample A with a frequency of 4.30 × 10^15 Hz can be calculated as;

wavelength of A = (3.00 ×  \(10^8\)  m/s) / (4.30 × 10^15 Hz)

wavelength of A = 6.98 ×  \(10^{-8}\) meters

For light sample B with a frequency of 8.70 × \(10^18\) Hz can be calculated as;

wavelength of B = (3.00 ×  \(10^8\) m/s) / (8.70 ×\(10^18\) Hz)

wavelength of B = 3.45 ×  \(10^{-11}\)  meters

Step-by-step explanation:

Answer: A

Step-by-step explanation: No Step-by-step explanation, just listen to me.

The given information is represented in the table as shown: Number of Hours, x, Since the Day Began0 5Number of Packaged Light Bulbs, y6,000 12,000Determine a linear function that models the relationship.

The number of packaged light bulbs is increasing linearly with respect to time. Therefore, we can use the slope-intercept form of the equation of a line, y = mx + b, where m is the slope and b is the y-intercept, to model the relationship.

Let x be the number of hours since the day began and y be the number of packaged light bulbs. Using the given information, we can determine the slope of the line as follows: slope = (change in y)/(change in x) = (12,000 - 6,000)/(5 - 0) = 1,200Thus, the equation of the line is: y = 1,200x + b We can use the coordinates of a point on the line to find the y-intercept. From the table, we see that the factory begins the day with 6,000 packaged light bulbs, which means that the point (0, 6,000) lies on the line. Substituting x = 0 and y = 6,000 into the equation of the line, we get:6,000 = 1,200(0) + b Simplifying, we get: b = 6,000Thus, the equation of the line is: y = 1,200x + 6,000The initial value of this function is 6,000 and the rate of change is 1,200.

The probability of less than two students going to college if six students are randomly selected from a school of 125 graduating seniors, and all the parents make over $75,000 per year is 0.0014 or 0.14%.

Given, Probability of a high school student going to college, when the parents make over $75,000 per year is 0.60.The total number of graduating seniors is 125.And, six students are randomly selected.

Let X be the number of students who go to college.If we assume that each student is independent of each other, then the probability that a student goes to college is 0.60, and the probability that a student does not go to college is 1 - 0.60 = 0.40.

Then the probability mass function of X is given by,\(P(X = k) = nCk * pk * (1 - p)n - kwhere n = 6, k = 0,1.P(X < 2) = P(X = 0) + P(X = 1) = (6C0 * 0.6^0 * 0.4^6) + (6C1 * 0.6^1 * 0.4^5) = (1 * 1 * 0.01024) + (6 * 0.6 * 0.32768) = 0.0014\)or 0.14%.Therefore, the probability that less than two students will actually go to college is 0.0014 or 0.14%.

A part-to-part ratio of 2:1 is described for every two parts of one component, there is one part of another component. This ratio indicates a proportional relationship between the quantities of these components.

In the previously described situation, where there is a part-to-part ratio of 2:1, it signifies the relationship between the quantities of two components. Specifically, it means that for every two parts of Component A, there is one part of Component B. This ratio provides a clear understanding of the relative amounts or proportions of these components in the given context.

For instance, if we have a total of 6 parts in the mixture, the ratio of 2:1 indicates that out of these 6 parts, 4 parts belong to Component A, while 2 parts belong to Component B. This implies that Component A is present in a larger proportion compared to Component B.

By expressing the ratio as 2:1, we can easily visualize the distribution or allocation of these components. It allows us to infer that Component A is twice as abundant or twice as prevalent as Component B. This ratio aids in understanding the composition of the mixture and the relative significance of each component in terms of quantity.

The solution to the original equation is approximately 1.4422.

To continue with the bounds found in part d, we need to use the interval [1.4, 1.5] as the initial approximation for the next iteration. Using the Newton-Raphson method, we get the following approximations:

- Iteration 2: x1 = 1.4428
- Iteration 3: x2 = 1.4422

Based on these two iterations, we can conclude that the solution to the original equation is approximately 1.4422. This is because the difference between the approximations in the last two iterations is only 0.0006, which is a small enough difference to suggest that the approximation has converged to a solution.

In other words, the Newton-Raphson method has been successful in finding a solution to the equation f(x) = x^3 - x^2 - x - 1 = 0 within the given interval [1.4, 1.5]. The method works by using the tangent line to the graph of f(x) at each iteration to approximate the root of the equation. By repeating this process, we are able to get closer and closer to the actual solution.

To evaluate the line integral along the path C given by x = 2t, y = 4t, where 0 ≤ t ≤ 1, we can follow these steps:

1. Rewrite the given integral in terms of t using the parameterization of the path: C: x = 2t, y = 4t.
2. Compute the derivatives dx/dt and dy/dt.
3. Substitute the parameterization and derivatives into the line integral.
4. Evaluate the integral over the specified interval.

Step 1:
The integral in terms of t is: ∫(3y² dy)

Step 2:
dx/dt = 2
dy/dt = 4

Step 3:
Substitute the parameterization and derivatives:
∫(3(4t)² * 4 dt) over the interval [0, 1]

Step 4:
Evaluate the integral:
∫(3 * 16t² * 4 dt) from 0 to 1
= 192 ∫(t² dt) from 0 to 1

Now, integrate and evaluate the integral:
= 192 * [1/3 * t^3] from 0 to 1
= 192 * (1/3 * 1^3 - 1/3 * 0^3)
= 64

The driving time along this stretch was reduced by 36% for a person who always drives at the speed limit.

To calculate the percent reduction in driving time along the stretch, we need to consider the effects of both the distance decrease and the speed increase.

First, let's assume the original distance of the stretch was D. After the reconstruction, the distance is now 0.8D (since it was decreased by 20%).

Next, let's assume the original speed limit was S. After the reconstruction, the speed limit is now 1.25S (since it was increased by 25%).

To calculate the original driving time along the stretch, we would use the formula: time = distance / speed. So the original driving time would be D/S.

After the reconstruction, the driving time would be (0.8D) / (1.25S) = 0.64D/S.

To calculate the percent reduction in driving time, we can use the formula: (original time - new time) / original time * 100%.

Plugging in the values we calculated, we get:

(original time - new time) / original time * 100% = (D/S - 0.64D/S) / (D/S) * 100% = 36%.
