Step-by-step explanation:
\(m = n + \frac{x}{p} \\ \\ \frac{x}{p} + n = m \\ \\ \frac{x}{p }= m - n \\ \\ x = m(p) - n(p) \\ \)
Answer:
p(m - n) = x
Step-by-step explanation:
You want to "solve for x." To do this, subtract n from both sides (for the purpose of isolating the x/p term):
m - n + x/p
Next, multiply all terms by p:
p(m - n) = x

sketch the region enclosed by the given curves. y = 3/x, y = 12x, y = 1 12 x, x > 0
To sketch the region enclosed by the given curves, we need to first plot each of the curves and then identify the boundaries of the region.The first curve, y = 3/x, is a hyperbola with branches in the first and third quadrants. It passes through the point (1,3) and approaches the x- and y-axes as x and y approach infinity.
The second curve, y = 12x, is a straight line that passes through the origin and has a positive slope.The third curve, y = 1/12 x, is also a straight line that passes through the origin but has a smaller slope than the second curve.To find the boundaries of the region, we need to find the points of intersection of the curves. The first two curves intersect at (1,12), while the first and third curves intersect at (12,1). Therefore, the region is bounded by the x-axis, the two straight lines y = 12x and y = 1/12 x, and the curve y = 3/x between x = 1 and x = 12.To sketch the region, we can shade the area enclosed by these boundaries. The region is a trapezoidal shape with the vertices at (0,0), (1,12), (12,1), and (0,0). The curve y = 3/x forms the top boundary of the region, while the straight lines y = 12x and y = 1/12 x form the slanted sides of the trapezoid.In summary, the region enclosed by the given curves is a trapezoid bounded by the x-axis, the two straight lines y = 12x and y = 1/12 x, and the curve y = 3/x between x = 1 and x = 12.

Help please.
Answer:
(a) -5
Step-by-step explanation:
The vertical scale factor for the graph and the function can be found by comparing the y-value of a point on f(x) to the y-value of a point on g(x). The graph conveniently marks two corresponding points with these y-values:
f(-2) = 2
g(-2) = -10
The value of k in g(x)=k·f(x) is the ratio of these y-values:
k = g(-2)/f(-2) = -10/2 = -5
The value of the vertical scale factor k is -5.

Deon plans to ride a 20-mi bicycle trail. If his average speed is 10 mi/h, how many hours will the ride take? Part 1: Solve the distance formula, d=rt d = r t , for t.
Answer:
The ride will take 2 h
Step-by-step explanation:
From the question,
Deon plans to ride a 20-mi bicycle trail, that is the total distance he plans to cover is 20-mi
Distance, d = 20 mi
Also, his average speed is 10 mi/h
rate of speed, r = 10 mi/h
To determine how many hours the ride will take,
From the formula,
d = rt
where
d is the distance covered
r is the average rate of speed
and t is the time.
We can solve for t, such
d = rt becomes
t = d/r
Now, from the question
d = 20 mi
r = 10 mi/h
∴ t = (20 mi) / (10 mi/h)
t = 2 h
Hence, the ride will take 2 h (hours)

Find the H.C.F. of 567 and 255 using Euclid’s division lemma.
Step-by-step explanation:
To find the Highest Common Factor (H.C.F.) of 567 and 255 using Euclid's division lemma, we can follow these steps:
Step 1: Apply Euclid's division lemma:
Divide the larger number, 567, by the smaller number, 255, and find the remainder.
567 ÷ 255 = 2 remainder 57
Step 2: Apply Euclid's division lemma again:
Now, divide the previous divisor, 255, by the remainder, 57, and find the new remainder.
255 ÷ 57 = 4 remainder 27
Step 3: Repeat the process:
Next, divide the previous divisor, 57, by the remainder, 27, and find the new remainder.
57 ÷ 27 = 2 remainder 3
Step 4: Continue until we obtain a remainder of 0:
Now, divide the previous divisor, 27, by the remainder, 3, and find the new remainder.
27 ÷ 3 = 9 remainder 0
Since we have obtained a remainder of 0, the process ends here.
Step 5: The H.C.F. is the last non-zero remainder:
The H.C.F. of 567 and 255 is the last non-zero remainder obtained in the previous step, which is 3.
Therefore, the H.C.F. of 567 and 255 is 3.
What is the major determinant of the permeability of a membrane to a specific ion?
The major determinant of the permeability of a membrane to a specific ion is "the quantity of open ion channels that are specific to that ion."
What is ion channels?Certain cells, known as excitable cells, are distinguished by their capacity to produce electrical signals.
Some key features regarding the open ion channels are-
Although there are many different types of excitable cells, such as neurons, muscle cells, & touch receptor cells, they all use ion channel receptors to transform chemical or mechanical messages in to the electrical signals.Whenever an ion channel is open, ions to move in a single-file fashion into and out of the cell. Individual ion channels are ion-specific, which means that they typically allow only one type of ion to pass via them. The amino acids that line a channel, as well as the physical width of the channel, determine which ions can pass from the cell's exterior to its interior, or vice versa.To know more about the ion channels, here

In Milgram's first study of obedience, the majority of teachers initially complied but refused to deliver more than slight levels of shock.
In Milgram's first study of obedience, participants were assigned the role of 'teacher' and were instructed to administer electric shocks to a 'learner' whenever they answered a question incorrectly. The shocks ranged from mild to severe, with the highest level labeled as 'XXX.' The learner was actually an actor, and no real shocks were administered.
The study found that the majority of teachers initially complied with the experimenter's orders and delivered shocks, but they refused to deliver more than slight levels of shock. This suggests that while they were willing to follow the instructions to some extent, they had moral reservations about causing significant harm to another person.
It is important to note that the study has been criticized for ethical concerns and the potential psychological harm it may have caused to participants. However, it remains a significant contribution to our understanding of obedience and the power of authority figures.

The correct statement is "only a and c are correct" so option g is the answer.
The statement that is true in a normal distribution is "approximately 70% of the values are within one standard deviation from the mean" (a), and "2.1% of the values are between -2 and -3 standard deviations from the mean" (c).
These statements are true because of the properties of a normal distribution, also known as a Gaussian distribution or bell curve. In a normal distribution, the majority of values cluster around the mean, with fewer and fewer values as you move further away from the mean.
The statement "twenty-seven percent of the values are between one and two standard deviations from the mean" (b) is not true, as the correct percentage is approximately 27.7% (68-95-99.7 rule).
The statement "0.1% of the values are 3 or higher standard deviations from the mean" (d) is also not true, as the correct percentage is approximately 0.3%.

find a minimum value for the radius of convergence of a power series solution about x=1 (x 1)y''-3xy' 2y=0
Following these steps will give you the minimum value for the radius of convergence (R) for the power series solution about x=1.
To find the minimum value for the radius of convergence of a power series solution about x=1 for the given differential equation (x-1)y'' - 3xy' + 2y = 0, we can follow these steps:
1. Assume a power series solution in the form: y(x) = Σ[a_n * (x-1)^n] for n=0 to infinity, where Σ denotes the sum from n=0 to infinity.
2. Compute y'(x) and y''(x):
y'(x) = Σ[n * a_n * (x-1)^(n-1)] for n=1 to infinity
y''(x) = Σ[(n-1) * n * a_n * (x-1)^(n-2)] for n=2 to infinity
3. Substitute y(x), y'(x), and y''(x) into the differential equation:
(x-1)Σ[(n-1) * n * a_n * (x-1)^(n-2)] - 3xΣ[n * a_n * (x-1)^(n-1)] + 2Σ[a_n * (x-1)^n] = 0
4. Match the coefficients of the power series in the equation for each power of (x-1). This will give you a recursive relation between the coefficients a_n.
5. Use the Ratio Test for convergence to find the minimum value of the radius of convergence (R):
R = lim (n→∞) |a_(n+1)/a_n|
6. Calculate the limit using the recursive relation found in step 4.
Following these steps will give you the minimum value for the radius of convergence (R) for the power series solution about x=1.
