What have I done wrong?

Answer:

f(x) = (x+5)(x-1)(x-3)

Step-by-step explanation:

From the graph, we have that the function intercepts the x-axis at the points x = -5, 1,3

From here, we have

x = -5

x = 1

x = 3

So we have the factors as;

x + 5, x - 1 , x - 3

So what this mean is that we have the function as;

f(x) = (x+5)(x-1)(x-3)

Answer:

x = -1/9

Step-by-step explanation:

\(\frac{18}{x} = -2\) multiply by 1/18 to cancel out

\(x = -2(\frac{1}{18} )\\x = -\frac{2}{18} \\x = -\frac{1}{9}\)

Hey there!

18/x = -2

Multiply both sides by x

-2x = 18

Divide both of your sides by -2

-2x/-2 = 18/-2

Cancel out: -2x/-2 because it gives you 1

Keep: 18/-2 because it helps us solve for our answer

x = 18/-2

18/-2 = 18 divided by -2 ➡️ -9

Thus your answer is: x = -9 ✅

Good luck on your assignment and enjoy your day!

TCP provides error checking to ensure reliable data delivery, making option A the correct answer. Only the propagation delay is not caused by the store-and-forward strategy employed by switching devices.

TCP (Transmission Control Protocol) provides error checking as part of its services. It ensures reliable data delivery by using acknowledgments and sequence numbers to detect and recover from packet loss, errors, or out-of-order delivery. When a TCP receiver receives data, it sends an acknowledgment (ACK) back to the sender to confirm the successful reception of packets. If the sender does not receive an ACK for a particular packet within a specified timeout period, it assumes the packet was lost or damaged and retransmits it.

TCP provides error checking to ensure reliable data delivery, making option A the correct answer.

The propagation delay is the time it takes for a signal to travel from the source to the destination. It is determined by the physical distance between the devices and the speed of signal propagation in the transmission medium. The propagation delay is an inherent characteristic of the medium and cannot be eliminated by switching devices or other strategies.

The other three options—processing delay, queuing delay, and transmission delay—are all caused by the store-and-forward strategy used by switching devices. Processing delay refers to the time taken to examine and process the packet headers. Queuing delay occurs when packets have to wait in a queue before being transmitted. Transmission delay is the time it takes to push the bits onto the transmission medium.

Among the given options, only the propagation delay is not caused by the store-and-forward strategy employed by switching devices.

3. The correct answer is A. The system is very well-engineered.

In a statistical multiplexing system, the queuing delay is the delay experienced by packets waiting in a queue before being transmitted. If the average queuing delay is very close to zero, it indicates that the system is well-engineered and efficiently managing its resources. A well-designed system can minimize or eliminate queuing delays by appropriately allocating resources and ensuring efficient scheduling algorithms.

Traffic intensity, which represents the ratio of the average traffic load to the transmission capacity, does not directly determine the queuing delay. It is possible to have low queuing delays even with high traffic intensity if the system is well-designed.

When the average queuing delay is close to zero, it suggests that the system is well-engineered and efficiently utilizing its resources, as stated in option A.

The results generated in the map phase are combined in the _reduce_ phase.

In maps, the "reduced phase" refers to a technique used to remove the phase ambiguity present in interferometric synthetic aperture radar (InSAR) data. InSAR uses radar to measure the distance between a satellite or aircraft and the ground and can be used to create detailed maps of changes in the surface of the earth over time.

However, because InSAR data is collected using radar waves, which are sensitive to the phase of the signal, the data can be affected by phase ambiguities. The reduced phase technique is used to remove these ambiguities and create more accurate maps.

The volume of the solid is 243/2 cubic units. To find the volume of the solid, we need to integrate the function z = 9 - y - x^2 over the bounded region in the first octant.

The region is bounded by the coordinate planes, so we have the limits of integration as follows:

0 ≤ x ≤ √9-y
0 ≤ y ≤ 9

The solid is bounded, so the integral will give us a finite volume:

V = ∫∫z dA, where the double integral is taken over the bounded region.

V = ∫[0,√9-y]∫[0,9] (9-y-x^2) dx dy

We can simplify the integrand by integrating with respect to x first:

V = ∫[0,9] ∫[0,√9-y] (9-y-x^2) dx dy
V = ∫[0,9] (9y - y^2 - 3(9-y)^2/2) dy
V = ∫[0,9] (-3y^2 + 54y - 243/2) dy
V = [-y^3/3 + 27y^2 - 243/2 y] [0,9]
V = 243/2

To determine whether the ratios 2/5 and 8/20 are equivalent, we'll convert them both to simplest terms and compare them. In addition, we'll use cross-multiplication to ensure that the fractions are equal.

2/5 can be simplified to simplest terms by dividing both the numerator and denominator by their highest common factor (HCF), which is 1. As a result, 2/5 in its simplest form is written as 2/5.

To simplify 8/20 to simplest terms, we must first determine the highest common factor of 8 and 20. The HCF of 8 and 20 is 4, which is the highest common factor.

We can reduce the fraction by dividing both the numerator and denominator by 4, resulting in 2/5.2/5 and 2/5 are equivalent to one another since they have the same numerator and denominator, implying that the ratios 2/5 and 8/20 are equivalent.

Because the numerators and denominators of these two fractions are both divisible by 2, we know that 2/5 and 8/20 are equivalent. As a result, the ratios 2/5 and 8/20 are equivalent. In conclusion, both ratios are equal since they are equivalent and are the same.

To determine whether the geometric series is convergent or divergent, we need to find the common ratio and use the convergence criterion for a geometric series.

Given the geometric series ∑(1 * 7^n), where n = 0 to infinity, we can see that the common ratio (r) is 7.
The convergence criterion for a geometric series is:

- If |r| < 1, then the series is convergent.
- If |r| ≥ 1, then the series is divergent.

In our case, |r| = |7| = 7.

Since 7 ≥ 1, the geometric series ∑(1 * 7^n) is divergent.

To harvest the crop in 2 days instead of 6 days, the farmer will need a total of 15 workers.

To calculate the number of workers needed, we can use the work formula:

Work = Workers × Time

1. Determine the total work needed to harvest the crop in the original scenario:
Original work = 5 workers × 6 days = 30 worker-days

2. Determine the total work needed to harvest the crop in the desired scenario:
Desired work = X workers × 2 days

3. Since the total work needed remains the same, we can set these two equations equal to each other:
30 worker-days = X workers × 2 days

4. Solve for the number of workers (X) needed to complete the harvest in 2 days:
X workers = 30 worker-days / 2 days
X workers = 15 workers

So, the farmer will need 15 workers to harvest the crop in 2 days.

a) The forecast is approximately miles. b) the Mean Absolute Deviation (MAD) based on the forecast is approximately miles. c) The forecast for year 6 is approximately miles. d) the last forecast is 3,468 miles.

a) To calculate the forecast for year 6 using a 2-year moving average, we take the average of the mileage for years 5 and 4. This provides us with the forecasted value for year 6.

b) The Mean Absolute Deviation (MAD) for the 2-year moving average forecast is calculated by taking the absolute difference between the actual mileage for year 6 and the forecasted value and then finding the average of these differences.

c) When using a weighted 2-year moving average, we assign weights to the most recent and previous periods. The forecast for year 6 is calculated by multiplying the mileage for year 5 by 0.40 and the mileage for year 4 by 0.60, and summing these weighted values.

The MAD for the weighted 2-year moving average forecast is calculated in the same way as in part b, by taking the absolute difference between the actual mileage for year 6 and the weighted forecasted value and finding the average of these differences.

d) Exponential smoothing involves assigning a weight (α) to the most recent forecasted value and adjusting it with the previous actual value. The forecast for year 6 is calculated by adding α times the difference between the actual mileage for year 5 and the previous forecasted value, to the previous forecasted value.

In this case, with α=0.20 and a forecast of 3,100 miles for year 1, we perform this exponential smoothing calculation iteratively for each year until we reach year 6, resulting in the forecasted value of approximately 3,468 miles.

The wind speed for the flight is 2 miles per hour.

Let's assume the wind speed is represented by "w" miles per hour.

When the drone flies with the wind, its effective speed is the sum of its own speed and the wind speed, so it travels at 5 + w miles per hour. Therefore, the time it takes to fly 35 miles with the wind is given by:

time = distance / speed

time = 35 / (5 + w)

Similarly, when the drone flies against the wind, its effective speed is the difference between its own speed and the wind speed, so it travels at 5 - w miles per hour. The time it takes to fly 15 miles against the wind is given by:

time = distance / speed

time = 15 / (5 - w)

Since the flight time is the same for both scenarios, we can set the two expressions for time equal to each other:

35 / (5 + w) = 15 / (5 - w)

Now, we can solve this equation to find the value of "w," the wind speed.

Cross-multiplying:

35(5 - w) = 15(5 + w)

175 - 35w = 75 + 15w

Combining like terms:

50w = 100
