If x - m is a factor of p(x), then p(m) = 0. This property is based on the fact that when a polynomial has a root, evaluating the polynomial at that root will result in zero.
If a student tests x = m and finds that x - m is a factor of the polynomial function p(x), it means that when x = m, p(x) is equal to zero. In other words, m is a root or a solution of the polynomial equation p(x) = 0.
When x - m is a factor of p(x), it implies that (x - m) divides p(x) evenly. This means that if we divide p(x) by (x - m), the remainder will be zero. In polynomial division, the dividend is p(x), the divisor is (x - m), and the quotient is the result of the division.
Let's consider an example to illustrate this further. Suppose we have the polynomial function p(x) = x² - 5x + 6. If we test x = 2, we can check if (x - 2) is a factor of p(x) by dividing p(x) by (x - 2):
x - 3
---------------
x - 2 | x² - 5x + 6
- (x² - 2x)
------------
-3x + 6
-(-3x + 6)
----------
0
As we can see, the division is exact with no remainder, which means that (x - 2) is indeed a factor of p(x). Therefore, when x = 2, p(x) will be equal to zero.
In general, if x - m is a factor of p(x), then p(m) = 0. This property is based on the fact that when a polynomial has a root, evaluating the polynomial at that root will result in zero.

Q1. A company explores crude from a reservoir at about 300m below the earth's surface. The explored oil is pumped is pumped at a rate of 2.0 kg/s to a storage tank, 15 meters above the ground level. a. Calculate the rate of change of potential energy in the oil at the point above the ground. b. For enhanced oil recovery, CO₂ is pumped from the same point above the ground into the reservoir. Determine the change of potential energy in the gas in the reservoir.
In this scenario, the rate of change of potential energy in the oil is calculated as it is pumped from a reservoir 300m below the earth's surface to a storage tank 15 meters above the ground.
a. To calculate the rate of change of potential energy in the oil, we need to consider the height difference between the reservoir and the storage tank. The potential energy change is given by the formula ΔPE = mgh, where m is the mass of the oil, g is the acceleration due to gravity, and h is the height difference.
In this case, the mass of oil being pumped per unit time is 2.0 kg/s, and the height difference is 300m - 15m = 285m. Thus, the rate of change of potential energy in the oil is (2.0 kg/s) × (9.8 m/s²) × (285m).
b. For the CO₂ pumped into the reservoir, the change of potential energy is determined similarly using the same formula. However, in this case, the height difference is between the ground level and the reservoir, which is 300m. The mass of CO₂ being pumped per unit time is not provided in the information given, so further calculations would require that information.
It's important to note that potential energy calculations involve the height difference and the mass of the substance being considered, multiplied by the acceleration due to gravity.

A 2 x 3 factorial design with between subjects variables was carried out with 8 subjects per cell. how many levels in the first factor and second factor, respectively?
In a 2 x 3 factorial design, the numbers 2 and 3 represent the levels of the first and second factors, respectively. Therefore, there are 2 levels in the first factor and 3 levels in the second factor.
In a factorial design, the numbers 2 and 3 do not directly represent the levels of the factors. The numbers indicate the number of levels present in each factor.
In a 2 x 3 factorial design, the "2" represents the number of levels in the first factor, and the "3" represents the number of levels in the second factor.
For example, let's say the first factor is "A" and it has two levels: Level 1 and Level 2. The second factor, "B," has three levels: Level 1, Level 2, and Level 3. The design would then involve combinations of these levels such as A1B1, A1B2, A1B3, A2B1, A2B2, and A2B3.
So, in a 2 x 3 factorial design, there are 2 levels in the first factor and 3 levels in the second factor, leading to a total of 6 unique combinations or cells.

Question:
Determine the value of m and n so that the following system of linear equation have an infinite number of solutions.
\((2m-1)x+3y-5=0\)
and
\(3x+(n-1)y-2=0\)
Answer:
\(m=\frac{17}{4}\)
\(n = \frac{11}{5}\)
Step-by-step explanation:
Given
\(3x+(n-1)y-2=0\)
\((2m-1)x+3y-5=0\)
Rewrite both equations:
\(3x + (n - 1)y = 2\)
\((2m - 1)x + 3y = 5\)
For the expression to have a solution, the following condition must exist:
\(\frac{3x}{(2m - 1)x} = \frac{(n-1)y}{3y}= \frac{2}{5}\)
Split to 2
\(\frac{3x}{(2m - 1)x} = \frac{2}{5}\)

22. If a pilot elects to proceed to the selected alternate, the landing minimums used at that airport should be
If a pilot elects to proceed to the selected alternate, the landing minimums used at that airport should be equal to or higher than the minimums required for the original destination airport.
When a pilot chooses to proceed to the selected alternate airport, they must consider the weather conditions at that airport, particularly the landing minimums. The landing minimums are the lowest weather conditions in which an aircraft can safely land at an airport. They are determined by various factors, such as the visibility range and the height of the cloud ceiling.
Therefore, if a pilot decides to go to the alternate airport, they should use the landing minimums for that airport to ensure a safe landing. The landing minimums for the alternate airport should be equal to or higher than the minimums required for the original destination airport.
It's important to note that the pilot must have knowledge of the landing minimums for the alternate airport before deciding to proceed there. If they don't have the necessary information, they should consider other options, such as returning to the departure airport or diverting to a different airport with suitable weather conditions.
In summary, when a pilot chooses to proceed to an alternate airport, they should use the landing minimums for that airport to ensure a safe landing. The pilot must have knowledge of the minimums before proceeding to the alternate airport.

Mr Rai sale a watch for Rs 2035 a profit of 10% how much money has he paid to buy the also find his profit amount
Answer:
He paid Rs 1,850 to buy the watch
Profit = Rs 185
Step-by-step explanation:
Cost price = x
Profit = 10% of x
Selling price = Rs 2035
Profit = Selling price - cost price
10% of x = 2035 - x
0.1x = 2035 - x
0.1x + x = 2035
1.1x = 2035
x = 2035 / 1.1
x = 1,850
Cost price = x = Rs 1,850
Profit = 10% of x
= 10% of 1,850
= 0.1 × 1850
= 185
Profit = Rs 185

Answer: I’m pretty sure its A on e2020
Step-by-step explanation:
It is an obligation to pay, but the spender has some control over the amount.
Option A is the correct answer.
We have,
The reason that a data usage bill for a smartphone is an essential (variable) expense is that it is an obligation to pay.
In other words, the phone service is necessary for the phone to function properly, and therefore, the bill must be paid.
However, the spender has some control over its amount by managing their data usage, such as turning off data for certain apps or using Wi-Fi instead of cellular data.
This means that while the bill cannot be eliminated entirely, the spender can take steps to reduce the amount owed.
Statement b is incorrect because while the bill cannot be eliminated entirely, it can be reduced by managing data usage.
Statement c is incorrect because the amount of the bill is not expected to be the same every month, as it will depend on how much data is used. Statement d is incorrect because while bills for services rendered may be a priority, they do not necessarily have a higher priority than other types of essential expenses, such as food or housing.

The z-score for a sales associate earning $37,500 in a system where the mean salary is $32,500 and the standard deviation is $2,500 has a z-score of 2. This score indicates that the associate's salary is two standard deviations above the mean.
Explanation:The z-score represents how many standard deviations a value is from the mean. In this case, the value is the salary of a sales associate, the mean is the average salary, and the standard deviation is the average variation in salaries.
We calculate the z-score by subtracting the mean from the value and dividing by the standard deviation, like so:
Z = (Value - Mean) / Standard Deviation
So, the z-score for an associate earning $37,500 would be:
Z = ($37,500 - $32,500) / $2,500

Which statement is true about the value of |-5|? It is the distance that -5 is form 0 on the number line. It is the distance that -5 from 5 on the number line. It is less than 5. It is greater than 5.
Answer: It is the distance that -5 is form 0 on the number line
Step-by-step explanation:
We can define the absolute value of any number:
IxI as:
"The distance between the point x and the origin in the coordinate axis"
If we are in one dimension, x is just a value, and the coordinate axis will be a number line.
Then we could rewrite this as:
"is the distance between the value x and the 0 in the number line"
So:
IxI = x if x > 0
IxI = -x if x < 0.
Then:
I -5 I
Is the distance between the number -5, and the 0 in the number line, and this is:
I - 5 I = 5.

Question 6 The function h(x) = defined as: f(x)= Question Help: Video < 1 can be expressed in the form f(g(x)) where g(z) = (x + 3) and f(x) is 2+3
The function h(x) can be written as the expression f(g(x)), where g(x) is defined to be equal to x + 3 and f(x) is defined to be equal to 2 + 3.
In the problem that has been presented to us, we have a function h(x) that needs to be represented in the form f(g(x)), where g(x) is defined as (x + 3), and f(x) is defined as 2 + 3. In order to accomplish this, we will need to change f(x) such that it reads g(x).
In the first step, we give f(x) the value of g(x) = (x + 3), which gives us the result f(g(x)) = f(x + 3). Next, we determine the value of f(x + 3) by plugging x + 3 into the equation f(x) = 2 + 3. Further simplification leads us to the conclusion that f(x + 3) = 2 + 3 = 5.
Therefore, the term h(x) can be rewritten as f(g(x)) = f(x + 3) = 5 to represent the same thing. This indicates that the output of the function h(x) will always be 5, regardless of the value of the argument x. To put it another way, the h(x) function is a constant function, which means that its value is always 5, despite the fact that x might be any value.

A double fault in tennis is when the serving player fails to land their serve "in" without stepping on or over the service line in two chances. Kelly's first serve percentage is 40%, while her second serve percentage is 70%.
c. Design a simulation using a random number generator that can be used to estimate the probability that Kelly double faults on her next serve.
The estimated probability of Kelly double faulting on her next serve would be (600 + 300) / 1000 = 0.9 or 90%.
To design a simulation using a random number generator to estimate the probability that Kelly double faults on her next serve, we can follow these steps:
1. Determine the probability of Kelly double faulting on her first serve:
- Given that her first serve percentage is 40%, the probability of Kelly landing her first serve "in" is 0.40.
- Therefore, the probability of Kelly double faulting on her first serve is the complement of 0.40, which is 1 - 0.40 = 0.60.
2. Determine the probability of Kelly double faulting on her second serve:
- Given that her second serve percentage is 70%, the probability of Kelly landing her second serve "in" is 0.70.
- Therefore, the probability of Kelly double faulting on her second serve is the complement of 0.70, which is 1 - 0.70 = 0.30.
3. Use a random number generator to simulate the serve:
- A random number generator can be used to generate a random number between 0 and 1.
- If the generated random number is less than or equal to 0.60, it represents Kelly double faulting on her first serve.
- If the generated random number is greater than 0.60 but less than or equal to 0.90, it represents Kelly double faulting on her second serve.
- If the generated random number is greater than 0.90, it represents Kelly successfully landing her serve "in".
4. Repeat the simulation multiple times:
- By repeating the simulation multiple times, we can obtain an average probability of Kelly double faulting on her next serve.
For example, if we repeat the simulation 1000 times, and Kelly double faults on her first serve in 600 instances and on her second serve in 300 instances, the estimated probability of Kelly double faulting on her next serve would be (600 + 300) / 1000 = 0.9 or 90%.
Remember, this is just an estimation based on the provided percentages and random number generation. The actual probability may vary in real-life situations.

You decide to rent a cottage you own. You spend $400 getting the cottage ready to put on the rental market. Your costs for utilities run approximately $15 per day. You think you can charge $115 per night in rent. Part A: Write an equation that represents your costs, C, in dollars for x number of nights. Part B: Write and equation that represents the Revenue (income), R, in dollars for x number of nights. Part C: What is the solution to this system of equations? Interpret the meaning of the solution.
Answer:
Part AThe costs consist of one off payment to get the cottage ready and daily utility charges:
C = 400 + 15xPart BThe revenue is the sum of daily rental:
R = 115xPart CTo solve it as a system we make C= R or:
400 + 15x = 115xSolving we get:
400 = 115x - 15x400 = 100xx = 400/100x = 4It gives us:
C = 400 + 15*4 = 460R = 115*4 = 460The meaning of the solution is the number of nights we can pay off the costs and after 4 days we start to get profit.
