Step-by-step explanation:

Answer:

y = 3x-6

Step-by-step explanation:

y = 3x−5

This is in slope intercept form

y = mx+b where m is the slope and b is the y intercept

m =3

Parallel lines have the same slope

We have the slope m=3 and a point (2,0)

y = mx+b

y = 3x+b

Substituting the point into the equation to solve for b

0 = 3(2)+b

0 = 6+b

b = -6

y = 3x-6

Answer:

y = 3x - 6

Step-by-step explanation:

Parallel lines have the same slope,

So m = 3

y - 0 = 3(x - 2)

y = 3x - 6

A parameterization {x[t], y[t]} of the line passing through the tips of X and Y when their tails are placed at (0, 0). Parametric Equation of line is L: x(t) = x(1)+t(x(2)-x(1)); y(t) = y(1)+t(y(2)-y(1)) or L = x + t(y-x).

We have to find a parameterization {x[t], y[t]} of the line passing through the tips of X and Y when their tails are placed at (0, 0).

Let tip of x is at (x(1), y(1)) ⇒ x = x(1)i + y(1)j

Let tip of y is at (x(2), y(2)) ⇒ y = x(2)i + y(2)j

Direction of line passing through tips of vectors.

x and y is d = y-x

d = (x(2)-x(1))i + (y(2)-y(1))j

Parametric Equation of line is

L: x(t) = x(1)+t(x(2)-x(1))

   y(t) = y(1)+t(y(2)-y(1))

OR

L = x + t(y-x)

The right question is:

For generic vectors X and Y, find a parameterization {x[t], y[t]} of the line passing through the tips of X and Y when their tails are placed at (0, 0).

Answer:

(1, 1) only.

Step-by-step explanation:

Hey! Let's help you with your question here!

Let's begin by understanding what is given to us. We know that the line contains the point (0, -1) and has a slope of 2. What can we infer from this? We can create a slope-intercept equation of a line! How do we do that? Well, if you recall, the slope-intercept form is:

\(y=mx+b\)

We already have our slope of m, which is 2. Now we just need to find b. But how do we do that? Given that the line contains the point (0, -1), We can substitute the point into x and y and solve for b! It would look like this:

\(-1=2(0)+b\)

\(-1=b\)

Now, that we've solved for b, we get the entire formula of:

\(y=2x-1\)

How do we know if the point is on the line or not? Well, for each point, we substitute the points (x and y) and see if they equal each other. If they don't, then they are not part of the line. If they do, they are considered part of the line. So it would be as such:

(2, 1):

\(y=2x-1\)

\(1=2(2)-1\)

\(1=4-1\)

\(1\neq 3\)

Since they don't equal each other, (2, 1) does not lie on the line.

(0, 1):

\(y=2x-1\)

\(1=2(0)-1\)

\(1\neq -1\)

Since they don't equal each other, (0, 1) does not lie on the line.

(1, 1):

\(y=2x-1\)

\(1=2(1)-1\)

\(1=2-1\)

\(1=1\)

Turns out they do equal each other! Therefore, (1, 1) does lie on the line.

So out of all that we tested, the only point that also lies on the line is (1, 1).

Answer:

The approximate period of the wave representing the airplane's path is 0.9 hours.

Step-by-step explanation:

The period of a wave is the time it takes for one complete cycle of the wave to occur. In the case of the airplane's path, this would be the time it takes for the airplane to complete one full oscillation, or "up and down" motion.

To find the period of the wave, we need to determine the value of x that corresponds to one complete cycle of the wave. In this case, the wave is defined by the function h(x) = 10000cos(0.0001x) + 20000.

To find the period, we can use the formula T = 2π/ω, where T is the period, π is the mathematical constant pi, and ω is the angular frequency of the wave. The angular frequency is related to the frequency of the wave, which is the number of cycles per second.

In this case, the angular frequency is given by the coefficient of the x term in the function, which is 0.0001. Plugging this value into the formula above, we get T = 2π/0.0001 = 200000π seconds.

Since one cycle of the wave corresponds to one complete oscillation of the airplane, the period of the wave is approximately 200000π seconds. This is a very large number, so it is usually more useful to express the period in minutes or hours. To convert to minutes, we can divide the period by 60, which gives us a value of about 3334 minutes. To convert to hours, we can divide the period by 3600, which gives us a value of about 0.9 hours.

In summary, the approximate period of the wave representing the airplane's path is 0.9 hours.

Ask me any questions you may have!

The amount of time it takes for a wave to complete one full cycle is known as the wave's period. This would be the amount of time needed for the plane to perform one full oscillation, or “up and down” motion, in the case of the flight path.

Finding the value of x that represents the wave's full cycle is necessary to calculate the wave's period. The equation h(x) = 10000cos(0.0001x) + 20000 in this instance defines the wave.

The formula T = 2/, where T is the period, is the mathematical constant pi, and is the wave's angular frequency, can be used to determine the period. The wave's frequency, or the number of cycles per second, and the angular frequency are connected.

We may convert the period to hours by dividing it by 3600, which gives us a number of approximately 0.9 hours.

Therefore, The wave that represents the course of the airplane has an approximate period of 0.9 hours.

Merkel's discs are not involved in sensory transduction.

The process by which sensory receptors in the body translate physical stimuli like light, sound, or pressure into electrical impulses that the brain can understand is known as sensory transduction. This procedure is necessary for recognizing our surroundings and reacting to them.

For example: Cones are specialized cells that are found in the retina of the eye and are in charge of vision in high light and color. They can transform the light of various wavelengths into electrical impulses that are sent to the brain because they are sensitive to light of those wavelengths. Whereas Merkel's discs, are specialized cells found in the skin that are involved in detecting touch and pressure. They do not play a role in sensory transduction.

Answer:

Step-by-step explanation:

Hello!

Consecutive integers are integers that come after each other. We want to find two consecutive even integers that when added give us 46.

Let the first consecutive even integer be x. Since even integers come every 2 integers (even, odd, even), the second even integer should be x + 2.

That means x + 2 should be 24.

The two numbers are 22 and 24.

Answer:

The area between z = 1.74 and z = 1.25 is of 0.065.

Step-by-step explanation:

Normal Probability Distribution:

Problems of normal distributions can be solved using the z-score formula.

In a set with mean \(\mu\) and standard deviation \(\sigma\), the z-score of a measure X is given by:

\(Z = \frac{X - \mu}{\sigma}\)

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the p-value, we get the probability that the value of the measure is greater than X.

The area between two values of Z is given by the subtraction of the pvalue of the larger value by the smaller.

The area between z = 1.74 and z = 1.25.

This is the pvalue of z = 1.74 subtracted by the pvalue of z = 1.25.

z = 1.74 has a pvalue of 0.959

z = 1.25 has a pvalue of 0.894

0.959 - 0.894 = 0.065

The area between z = 1.74 and z = 1.25 is of 0.065.

Step-by-step explanation:

Answer:

The question asks us to identify which of the provided graphs represents a function.

A relationship can be called a function only if one x-value corresponds to exactly one y-value.

To know if a relationship is a function from its graph, we can use something called the vertical line test. This is where you draw (or imagine) a vertical line going through the graph. If the line touches the curve exactly once, it passes the test and is a function.

In this question, for the first option, if we imagine a vertical line going through the graph, we can see that it touches the graph continuously at x = 1. Therefore, it is not a function.

Similarly, for the second and third options, the vertical lines would touch the graph twice. Therefore, they aren't functions either.

Finally, for the last option, we can see that a vertical line would touch the graph exactly once at every value of x. Therefore, it is a function.

Answer: x = 50, m∠N = 50°

Step-by-step explanation:

x = 50, m∠N = 50°

Since ∠M and ∠N are supplementary, the two angles add up to 180°. Therefore, m∠N = 180° - 37° = 143°. Because m∠N = 13x, we can solve for x by dividing both sides by 13, which gives x = 50. Therefore, m∠N = 13x = 13(50) = 50°.
