To find the component form of the velocity of the airplane, we need to resolve the velocity vector into its horizontal and vertical components.

Assuming that the bearing of 110 degrees is measured clockwise from the North, the horizontal component of the velocity is given by:

cos(110 degrees) = -sin(20 degrees) ≈ -0.342

Horizontal component = 560 mph * (-0.342) ≈ -191.5 mph

Similarly, the vertical component of the velocity is given by:

sin(110 degrees) = cos(20 degrees) ≈ 0.940

Vertical component = 560 mph * 0.940 ≈ 526.4 mph

Therefore, the component form of the velocity of the airplane is approximately (-191.5 mph, 526.4 mph).

Step-by-step explanation:

If the arithmetic sequence is f(x) = 3x-7, x stands for the position of the number in the sequence. In other words, we are looking to solve for x when f(x) = 8:

8 = 3x - 7 and

15 = 3x so

x = 5. The position of the number 8 is the 5th position.

What does this problem ask for:

 --> position of '8' in the sequence

Since our general formula: f(x) = 3x - 7

 --> 'x' represents the position of the term in the sequence

    --> f(x) is the term in the sequence

 --> therefore, if we plug '8' into f(x)

    --> we can find 'x' which is the position of 8 in the sequence

Thus:

 \(8=3x-7\\3x=8+7\\3x=15\\x=5\)

8 is the 5th term

Answer: 5th term

Step-by-step explanation:

The area of a rectangle is typically written as:

\(A = l x w\)

where: l represents the length and w represents the width.

Since, in the given problem, we already know the value of the length which is 14.4 inches, and the value of width is one-third of the length. Thus, the width would be:

\(= (14.4)(\frac{1}{3})\\= \frac{24}{5} \\= 4.8 inches\)

We will simply substitute this value to the formula to get the area.

\(A = lxw\\A = (14.4)(4.8)\\A = 69.12 in^{2}\)

Explanation:

Through some strange formatting error, the tickmarks are not in the proper locations. They should be to the right and slightly above the letter. They should be close by, and not far away like that.  

It looks like the purple figure is the image while the blue figure is the preimage. If that's the case, then we've applied a 90 degree counterclockwise rotation to go from blue to purple.

Notice how angle AQA' is 90 degrees as shown by the green segments in the diagram below. So are BQB' and CQC' and DQD' as well.

We could also rotate the blue figure 270 degrees clockwise to arrive at the same purple image. Note how 90+270 = 360 which is a full circle.

Answer:

(2, 4 )

Step-by-step explanation:

Given the 2 equations

y = 2x → (1)

x = - y + 6 → (2)

Substitute x = - y + 6 into (1)

y = 2(- y + 6) ← distribute

y = - 2y + 12 ( add 2y to both sides )

3y = 12 ( divide both sides by 3 )

y = 4

Substitute y = 4 into (2) for corresponding value of x

x = - 4 + 6 = 2

solution is (2, 4 )

To find the critical points at which profit is maximized given the total revenue TR = 4700 - 302 and total cost TC = 320/10,500, we need to compute the marginal revenue and marginal cost, equate MR = MC to find the optimal quantity Q∗, verify if Q∗ is a relative maximum point, and compute the maximum profit level (π) by evaluating π∗ = 9(π(Q∗)).

Marginal Revenue (MR) is the derivative of the total revenue function with respect to quantity (Q). In this case, MR = dTR/dQ. By taking the derivative of TR = 4700 - 302 with respect to Q, we can find the expression for MR.

Marginal Cost (MC) is the derivative of the total cost function with respect to quantity (Q). In this case, MC = dTC/dQ. By taking the derivative of TC = 320/10,500 with respect to Q, we can find the expression for MC.

To find the optimal quantity Q∗, we equate MR and MC by setting MR = MC and solve for Q. This is because profit is maximized when MR equals MC.

Once we have found Q∗, we need to verify if it is a relative maximum point. This can be done by checking the second derivative of the profit function and determining if it is negative at Q∗. If the second derivative is negative, it confirms that Q∗ is a relative maximum point.

Finally, to compute the maximum profit level (π∗), we evaluate π(Q∗) by substituting Q∗ into the profit function. In this case, we can multiply the value of π(Q∗) by 9 to obtain the maximum profit level (π∗).

The solution to the given differential equation 2xy(dy/dx) = y², with the initial condition y(2) = 3, is y = (27 * e⁽ˣ⁻²⁾\()^{1/4}\).

To solve the given differential equation

2xy(dy/dx) = y²

We will use separation of variables and integrate to find the solution.

Start with the given equation

2xy(dy/dx) = y²

Divide both sides by y²:

(2x/y) dy = dx

Integrate both sides:

∫(2x/y) dy = ∫dx

Integrating the left side requires a substitution. Let u = y², then du = 2y dy:

∫(2x/u) du = ∫dx

2∫(x/u) du = ∫dx

2 ln|u| = x + C

Replacing u with y²:

2 ln|y²| = x + C

Using the properties of logarithms:

ln|y⁴| = x + C

Exponentiating both sides:

|y⁴| = \(e^{x + C}\)

Since the absolute value is taken, we can remove it and incorporate the constant of integration

y⁴ = \(e^{x + C}\)

Simplifying, let A = \(e^C:\)

y^4 = A * eˣ

Taking the fourth root of both sides:

y = (A * eˣ\()^{1/4}\)

Now we can incorporate the initial condition y(2) = 3

3 = (A * e²\()^{1/4}\)

Cubing both sides:

27 = A * e²

Solving for A:

A = 27 / e²

Finally, substituting A back into the solution

y = ((27 / e²) * eˣ\()^{1/4}\)

Simplifying further

y = (27 *  e⁽ˣ⁻²⁾\()^{1/4}\)

Therefore, the solution to the given differential equation with the initial condition y(2) = 3 is

y = (27 * e⁽ˣ⁻²⁾\()^{1/4}\)

Step-by-step explanation:

To calculate the probability that none of the selected subjects left the treatment center against medical advice, we need to know the total number of subjects transported by helicopter and the number of subjects who left against medical advice.

Let's assume the total number of subjects transported by helicopter is 'N' and the number of subjects who left against medical advice is 'A'.

The probability that none of the selected subjects left against medical advice can be calculated using the hypergeometric probability formula:

P(X = 0) = (C(A, 0) * C(N - A, n)) / C(N, n)

Where:

C(n, r) represents the number of combinations of selecting 'r' items from a set of 'n' items.

In this case, since we want to calculate the probability of selecting none of the subjects who left against medical advice, we set X = 0.

Substituting the values, we have:

P(X = 0) = (C(A, 0) * C(N - A, n)) / C(N, n)

Simplifying further:

P(X = 0) = (C(0, 0) * C(N - A, n)) / C(N, n)

Since C(0, 0) = 1 (by convention), the formula becomes:

P(X = 0) = (1 * C(N - A, n)) / C(N, n)

Now, you need to provide the values of 'N', 'A', and 'n' in order to calculate the probability.

Ravi présent âge 15 because présent would be 20:15 and then it would turn into 25:20

Answer:

15 years old

Step-by-step explanation:

Given the ratio of their ages = 4 : 3 = 4x : 3x ( x is a multiplier )

Then in 5 years the ratio of their ages is 4x + 5 : 3x + 5 = 5 : 4, that is

\(\frac{4x+5}{3x+5}\) = \(\frac{5}{4}\) ( cross- multiply )

4(4x + 5) = 5(3x + 5) ← distribute both sides

16x + 20 = 15x + 25 ( subtract 15x from both sides )

x + 20 = 25 ( subtract 20 from both sides )

x = 5

Thus

Ravi's age is 3x = 3 × 5 = 15

To calculate P(A and B), you need to use the formula for the probability of two events occurring together.

The formula is:

P(A and B) = P(A) x P(B | A) Where P(A) is the probability of event A occurring, and P(B | A) is the probability of event B occurring given that event A has already occurred.

1. Determine the probability of event A occurring. This will be your P(A) value.

2. Determine the probability of event B occurring given that event A has already occurred. This will be your P(B | A) value.

3. Multiply P(A) and P(B | A) together to get P(A and B). For example, let's say that event A is rolling a 6 on a six-sided die, and event B is flipping a coin and getting heads. The probability of event A occurring is 1/6, and the probability of event B occurring given that event A has already occurred is 1/2.

So:

P(A and B) = P(A) x P(B | A) P(A and B) = (1/6) x (1/2) P(A and B) = 1/12

So the probability of both events occurring together is 1/12.

It takes a train going 50 mph approximately 11/2 miles to stop safely.

The distance a train takes to come to a stop can be determined by several factors, including the speed of the train, the weight of the train, the condition of the brakes and the track, and the reaction time of the engineer.

In general, a train going 50 mph will take about 1 1/2 miles or 8,000 feet to stop safely. This is because a train moving at 50 mph is traveling at about 75 feet per second, and it takes a significant distance to slow down a heavy object moving at such a high speed.

The statement "Both linear regression and logistic regression are linear models" is false. The statement "The decision boundary in logistic regression is in S-shape due to the sigmoid function" is true.

Linear Regression and Logistic Regression are two types of regression analysis.Linear Regression is a regression analysis technique used to determine the relationship between a dependent variable and one or more independent variables.Logistic Regression is a type of regression analysis that is used when the dependent variable is binary, which means it has two possible outcomes (usually coded as 0 or 1).In simple terms, Linear Regression is used for continuous data, whereas Logistic Regression is used for categorical data.

As for the second statement, it is true that the decision boundary in logistic regression is in S-shape due to the sigmoid function. The sigmoid function is an S-shaped curve that is used to map any input to a value between 0 and 1. This function is used in logistic regression to model the probability of a certain event occurring.

The decision boundary is the line that separates the two classes, and it is typically S-shaped because of the sigmoid function.
