Answer:
94, 188, 564
Step-by-step explanation:
let x be the first part then the second part is 2x and third part is 3 × 2x = 6x
then
x + 2x + 6x = 846 , that is
9x = 846 ( divide both sides by 9 )
x = 94
2x = 2 × 94 = 188
6x = 6 × 94 = 564

The area of the surface S is \((8\sqrt{3}\pi\)\)).
To calculate the area of the surface S, which is the portion of the cylinder x² + y² = 4 that lies between z= 4 and z= 5, we can use the formula for the surface area of a surface of revolution.
The formula for the surface area of a surface of revolution is:
\(\[A = 2\pi \int_{a}^{b} f(x) \sqrt{1 + \left(\frac{dy}{dx}\right)^2} dx\]\)
The limits of integration for x are the values that correspond to the points where the curve intersects the planes z= 4 or z =5.
For z= 4, we have
y= √4-x² and z=4, so we substitute these values into the equation of the cylinder: \(\((\sqrt{4 - x^2})^2 + z^2 = 4\)\) we get x=0.
For z= 5, we have
y= √4-x² and z=5, so we substitute these values into the equation of the cylinder: \(\((\sqrt{4 - x^2})^2 + z^2 = 4\)\). we get \(\(x = \pm \sqrt{3}\).\)
Now we can calculate the area:
\(\[A = 2\pi \int_{-\sqrt{3}}^{\sqrt{3}} 2 \sqrt{1 + \left(\frac{dy}{dx}\right)^2} dx\]\)
To find \(\(\frac{dy}{dx}\),\) we differentiate \(\(y = \sqrt{4 - x^2}\)\)with respect to x:
\(\[\frac{dy}{dx} = \frac{-x}{\sqrt{4 - x^2}}\]\)
Substituting this into the integral, we have:
\(\[A = 2\pi \int_{-\sqrt{3}}^{\sqrt{3}} 2 \sqrt{1 + \left(\frac{-x}{\sqrt{4 - x^2}}\right)^2} dx\]\)
Simplifying the integrand:
\(\[A = 2\pi \int_{-\sqrt{3}}^{\sqrt{3}} 2 \sqrt{1 + \frac{x^2}{4 - x^2}} dx\]\[A = 2\pi \int_{-\sqrt{3}}^{\sqrt{3}} 2 \sqrt{\frac{4 - x^2 + x^2}{4 - x^2}} dx\]\[\)
\(A = 2\pi \int_{-\sqrt{3}}^{\sqrt{3}} 2 \sqrt{\frac{4}{4 - x^2}} dx\]\)
Now, we can substitute \(\(u = \frac{x}{\sqrt{4 - x^2}}\)\), which simplifies the integrand:
\(\[du = \frac{\sqrt{4 - x^2} + x \cdot \frac{-2x}{2\sqrt{4 - x^2}}}{4 - x^2} dx\]\)
\(\[du = \frac{\sqrt{4 - x^2} - \frac{2x^2}{\sqrt{4 - x^2}}}{4 - x^2} dx\]\)
\(\[du = \frac{4 - 3x^2}{(4 - x^2)\sqrt{4 - x^2}} dx\]\)
Simplifying the integral further:
\(\[A = 2\pi \int_{-\sqrt{3}}^{\sqrt{3}} 2 \sqrt{\frac{4}{4 - x^2}} dx\]\[A = 4\pi \int_{-\sqrt{3}}^{\sqrt{3}} \frac{\sqrt{4 - x^2}}{\sqrt{4 - x^2}} dx\]\[A = 4\pi \int_{-\sqrt{3}}^{\sqrt{3}} 1 dx\]\)
Integrating 1 with respect to \(x\), we get:
\(\[A = 4\pi [x]_{-\sqrt{3}}^{\sqrt{3}}\]\[A = 4\pi \left(\sqrt{3} - (-\sqrt{3})\right)\]\[A = 4\pi (2\sqrt{3})\]\[A = 8\sqrt{3}\pi\]\)
Therefore, the area of the surface S is \((8\sqrt{3}\pi\)\)).

What is a triangle with 3 obtuse angles?
A triangle with three obtuse angles is called an obtuse triangle.
In an obtuse triangle, all three angles are obtuse, which means that they are greater than 90 degrees. This is in contrast to a right triangle, which has one right angle (90 degrees) and two acute angles, or an acute triangle, which has three acute angles (all less than 90 degrees). Obtuse triangles can be either scalene (all sides have different lengths) or isosceles (two sides have the same length). They cannot be equilateral, because in an equilateral triangle all three angles are equal to 60 degrees, which is less than 90 degrees.

When given Hop -0.85 and a -0.10, the level of confidence that should be used to test the claim is D) 95%. Explanation: IN hypothesis testing, the level of confidence refers to the percentage of all possible samples that can be expected to include the true population parameter.
It is written in percentage form, and common choices for the level of confidence include 90%, 95%, and 99%.For example, if we want to construct a 95% confidence interval for a population mean, this means that if we were to construct 100 different 95% confidence intervals using 100 different samples, then 95 of those intervals should contain the true population mean.
The appropriate level of confidence to use is the one that will allow the rejection of the null hypothesis if the sample statistics are unlikely to have occurred by chance. Thus, the level of confidence that is appropriate for testing the claim is 95%.

Suppose professor nahele at the university of minnesota gave a quiz to 10 students. assume that it is possible to get a grade between 0 and 10 on the quiz.
The mean score has an equal probability of occurring of the scores in the uniformly distributed quiz is 5.5.
In a uniform distribution where the scores range from 1 to 10, each possible score has an equal probability of occurring. To find the mean (or average) of the scores, we can use the formula:
Mean = (Sum of all scores) / (Number of scores)
In this case, the sum of all scores can be calculated by adding up all the individual scores from 1 to 10, which gives us:
Sum of scores = 1 + 2 + 3 + 4 + 5 + 6 + 7 + 8 + 9 + 10 = 55
The number of scores is 10 since there are 10 possible scores from 1 to 10.
Plugging these values into the formula, we get:
Mean = 55 / 10 = 5.5
Therefore, the mean of the scores in this quiz is 5.5.

The responsibility of group leaders in assisting members in the development of their personal goals should be done in a ""_____________"" manner.
The responsibility of group leaders in assisting members in the development of their personal goals should be done in a "facilitative" manner.
When group leaders assist members in their personal goal development, being facilitative means they take on a supportive role that empowers individuals to identify and work towards their goals effectively. Rather than imposing their own goals or solutions, facilitative leaders create an environment that encourages open communication, active listening, and collaboration.
Facilitative leaders help members explore their aspirations, clarify their goals, and break them down into actionable steps. They provide guidance, resources, and feedback, while also promoting autonomy and self-directed learning. They create a safe space for individuals to share their goals, seek advice, and engage in discussions with other group members.
By adopting a facilitative approach, group leaders can empower individuals to take ownership of their personal goals, foster a sense of motivation and accountability, and promote personal growth and development within the group dynamic.

The water capacity of a tank is 1500 liters. In three hours, half of it is being discharged. Find the volume left after 4 hours of discharging. a. 1,000 liters b. 800 liters c. 500 liters
After 4 hours of discharging, the volume left in the tank would be 500 liters. The correct option is C.
Initially, the tank has a water capacity of 1500 liters.
After three hours of discharging, half of the water is discharged, which means 1500/2 = 750 liters have been removed from the tank.
To find the volume left after 4 hours of discharging, we need to subtract the additional amount discharged in the fourth hour.
Since the discharge rate remains the same, we can calculate the amount discharged in one hour as 750/3 = 250 liters.
Therefore, in the fourth hour, 250 liters would be discharged. Subtracting this from the remaining water after three hours (750 liters), we get 750 - 250 = 500 liters.
Therefore, the correct answer is c. 500 liters.

If a firm permanently borrows $100 million at an interest rate of 8%, the present value of the interest tax shield is $2.4 million.
The following formula can be used to determine the present value of the interest tax shield:
PV(Tax Shield) = Tax Rate × Interest Expense
From the question:
Firm borrows $100 million
Interest rate is 8%
Tax rate is 30%
Let's first determine the interest expense:
Interest Expense = Borrowed Amount × Interest Rate
Interest Expense = $100 million × 8%
Interest Expense = $8 million
Now, we can calculate the present value of the interest tax shield:
PV(Tax Shield) = Tax Rate × Interest Expense
PV(Tax Shield) = 30% × $8 million
PV(Tax Shield) = $2.4 million
Therefore, the present value of the interest tax shield is $2.4 million.

How large should we choose n so that the trapezoid-rule approximation, Tn, to the integral sin r dz is accurate to within 0.00001? (Use the error bound given in Section 5.9 of the course text.)
The trapezoidal rule is a numerical integration method that uses trapezoids to estimate the area under a curve. The trapezoidal rule can be used for both definite and indefinite integrals. The trapezoidal rule approximation, Tn, to the integral sin r dz is given by:
Tn = (b-a)/2n[f(a) + 2f(a+h) + 2f(a+2h) + ... + 2f(b-h) + f(b)]where h = (b-a)/n. To determine how large n should be so that Tn is accurate to within 0.00001, we can use the error bound given in Section 5.9 of the course text. According to the error bound, the error, E, in the trapezoidal rule approximation is given by:E ≤ ((b-a)³/12n²)max|f''(x)|where f''(x) is the second derivative of f(x). For the integral sin r dz, the second derivative is f''(r) = -sin r. Since the absolute value of sin r is less than or equal to 1, we have:max|f''(r)| = 1.
Substituting this value into the error bound equation gives:E ≤ ((b-a)³/12n²)So we want to choose n so that E ≤ 0.00001. Substituting E and the given values into the inequality gives:((b-a)³/12n²) ≤ 0.00001Simplifying this expression gives:n² ≥ ((b-a)³/(0.00001)(12))n² ≥ (b-a)³/0.00012n ≥ √(b-a)³/0.00012Now we just need to substitute the values of a and b into this expression. Since we don't know the upper limit of integration, we can use the fact that sin r is bounded by -1 and 1 to get an upper bound for the integral.
For example, we could use the interval [0, pi/2], which contains one full period of sin r. Then we have:a = 0b = pi/2Plugging in these values gives:n ≥ √(pi/2)³/0.00012n ≥ 5073.31Since n must be an integer, we round up to the nearest integer to get:n = 5074Therefore, we should choose n to be 5074 so that the trapezoidal rule approximation, Tn, to the integral sin r dz is accurate to within 0.00001.
