Answer:

1571in^3

Step-by-step explanation:

Given data

h= 20 in

d= 10 in

r= 10/2= 5 in

V= πr^2h

substitute

V= 3.142*5^2*20

V=3.142*25*20

V=1571 in^3

Hence the volume is 1571in^3

To find the differential of the function y = s / (5 + 9s), we differentiate it with respect to s. The resulting differential gives us an expression for the rate of change of y with respect to s.

To differentiate the function y = s / (5 + 9s) with respect to s, we use the quotient rule of differentiation. The quotient rule states that for a function u/v, the derivative is given by (v * du/ds - u * dv/ds) / v^2.

In this case, u = s and v = (5 + 9s). Using the quotient rule, we have:

dy/ds = [(5 + 9s) * d/ds(s) - s * d/ds(5 + 9s)] / (5 + 9s)^2

Since d/ds(s) = 1 and d/ds(5 + 9s) = 9, we can simplify the expression:

dy/ds = (5 + 9s - 9s) / (5 + 9s)^2

Simplifying further, we have:

dy/ds = 5 / (5 + 9s)^2

Therefore, the differential of the function y = s / (5 + 9s) is dy/ds = 5 / (5 + 9s)^2. This represents the rate of change of y with respect to s.

To find the differential of the function y = s / (5 + 9s), we differentiate the function with respect to s. The resulting differential represents the change in y for a small change in s.

We start by rewriting the given function as y = s / (5 + 9s) = s(5 + 9s)^(-1). To find the differential, we differentiate this function with respect to s using the quotient rule.

Applying the quotient rule, the derivative of y with respect to s is given by:

dy/ds = (5 + 9s)^(-1) - s(9)(5 + 9s)^(-2)(9) = (5 + 9s)^(-1) - 81s(5 + 9s)^(-2)

Therefore, the differential of the function y = s / (5 + 9s) is dy/ds = (5 + 9s)^(-1) - 81s(5 + 9s)^(-2). This expression represents the rate of change of y with respect to s.

Answer:

\( \huge{x = \frac{7}{2} }\)

Step-by-step explanation:

5(x - 9) + 3(x + 4) = 2(x - 6)

First expand the terms in the bracket

That's

5x - 45 + 3x + 12 = 2x - 12

It is possible to design any statistical learning problem to minimize predicted loss. All data examples in problem 1 correspond to supervised learning.

What is supervised learning?

The use of labelled datasets distinguishes the machine learning strategy known as supervised learning. These datasets are intended to "supervise" or "train" algorithms to correctly classify data or forecast outcomes. Labeled inputs and outputs allow the model to monitor its precision and improve over time.

When using data mining, supervised learning may be divided into two categories: classification and regression.

Using an algorithm, classification issues correctly categories test data into distinct groups, such as distinguishing apples from oranges.

Another supervised learning technique that employs an algorithm to comprehend the link between dependent and independent variables is regression.

The correct option is D. 1/4 of the distance from A to B.

D. 1/4 of distance from A to B.

The potential energy of a spring varies with the displacement of the object from its equilibrium position. At the equilibrium position, the potential energy is at a minimum, and the kinetic energy is at its maximum. As the object moves away from the equilibrium position, the potential energy increases and the kinetic energy decreases until the object reaches the maximum displacement point, where the potential energy is at a maximum and the kinetic energy is at a minimum.

In the case of a vertical spring, the equilibrium position is the midpoint between the two extreme points, A and B. At this point, the object has zero potential energy and maximum kinetic energy. As the object moves away from the equilibrium position towards point A, its potential energy increases and its kinetic energy decreases until it reaches point A, where the potential energy is at a maximum and the kinetic energy is at a minimum. Therefore, the object is located at point A when the kinetic energy is at a minimum.

Since the spring is ideal and massless, the potential energy is proportional to the square of the displacement from the equilibrium position. The kinetic energy is proportional to the square of the velocity of the object. At point A, the velocity of the object is zero, and hence the kinetic energy is at a minimum. Therefore, the object is located at point A when the kinetic energy is a minimum.

The distance from A to B is divided into four equal parts, and the object is located at the first quarter point from A to B, which is 1/4 of the distance from A to B. Therefore, the correct option is D. 1/4 of the distance from A to B.

Last worked 39 hours and earned $553.22. Enter and solve an equation to find Julio's normal hourly rate,

The spring stretched from 18 inches to 24 inches, producing a total of 12 joules of work.

The formula: gives the work done on a spring when it is stretched.

W = (1/2)kx²

where W is the amount of work completed, k is the spring's constant, and x is the spring's length change. We can use the equation to determine the spring constant:

F = kx

where F is the spring's applied force and x is the spring's altered length. Since we are aware that a spring with a natural length between 12 and 18 inches will be stretched by a force of 4 pounds, we can enter these numbers into the equation to determine k:

4 = k * (18 - 12)

4 = k * 6

k = 4/6

k = 2/3

Now that we know the spring constant, we can use the work formula to calculate the total amount of work required to extend a spring from 18 inches to 24 inches in length:

W = (1/2)kx²

W = (1/2)(2/3)(24 - 18)²

W = (1/2)(2/3)(6²)

W = (1/2)(2/3)(36)

W = (2/3)(18)

W = 12

So The spring stretched from 18 inches to 24 inches, producing a total of 12 joules of work.

The probability that both digits in a New York State daily lottery game are different is 0.9, or 9 out of 10.

To find the probability that both digits in a New York State daily lottery game are different, we need to first calculate the total number of possible outcomes. Since there are 10 digits (0-9) that can be selected for each of the two digits in the sequence, there are a total of 10 x 10 = 100 possible outcomes.

Now, we need to determine the number of outcomes where both digits are different. There are 10 possible choices for the first digit and only 9 possible choices for the second digit, since we cannot choose the same digit as the first. Therefore, there are a total of 10 x 9 = 90 outcomes where both digits are different.

The probability of both digits being different is equal to the number of outcomes where both digits are different divided by the total number of possible outcomes. Thus, the probability is 90/100, which simplifies to 9/10, or 0.9.

In summary, the probability that both digits in a New York State daily lottery game are different is 0.9, or 9 out of 10. This means that there is a high likelihood that both digits selected will be different.

Answer:

m∠JKM = 63°

m∠MKL = 27°

Step-by-step explanation:

Since ∠JKL is a right angle. This means that by summing up both m∠JKM and m∠MKL will result in the same as ∠JKL figure. Thus, m∠JKM + m∠MKL = m∠JKL which is 90° by a right angle definition.

\(\displaystyle{\left(12x+3\right)+\left(6x-3\right) = 90}\)

Solve the equation for x:

\(\displaystyle{12x+3+6x-3 = 90}\\\\\displaystyle{18x=90}\\\\\displaystyle{x=5}\)

We know that x = 5. Next, we are going to substitute x = 5 in m∠JKM and m∠MKL. Thus,

m∠JKM = 12(5) + 3 = 60 - 3 = 63°

m∠MKL = 6(5) - 3 = 30 - 3 = 27°

Length of the rope holding Kayla to the boat = 240 meters

Horizontal distance of Kayla from the boat = x = 181 meters

Let the distance of Kayla above the boat = y meters

Triangle formed is a right triangle. Therefore, by applying Pythagoras theorem in the given triangle,

x² + y² = (240)²

(181)² + y² = (240)²

y = \(\sqrt{57600-32761}\)
