They are related as u^T transposes of each other. v and v^T u are scalar values that represent the dot product of u and v. uv^T and vu^T are matrices of size n x n that represent the outer product of u and v.

If u and v are vectors in R^n, then:

u^T v and v^T u are related as transposes of each other. Specifically, if

u = [u_1, u_2, ..., u_n]^T

and v = [v_1, v_2, ..., v_n]^T

then:

u^T v = v^T u

= u_1 * v_1 + u_2 * v_2 + ... + u_n * v_n

So, u^T v and v^T u are scalar values that represent the dot product of u and v.

uv^T and vu^T are related as transposes of each other. Specifically, if u = [u_1, u_2, ..., u_n]^T and v = [v_1, v_2, ..., v_n]^T

then:

uv^T = [u_1 * v_1, u_1 * v_2, ..., u_1 * v_n;

u_2 * v_1, u_2 * v_2, ..., u_2 * v_n;

...;

u_n * v_1, u_n * v_2, ..., u_n * v_n]

vu^T = [v_1 * u_1, v_2 * u_1, ..., v_n * u_1;

v_1 * u_2, v_2 * u_2, ..., v_n * u_2;

...;

v_1 * u_n, v_2 * u_n, ..., v_n * u_n]

So, uv^T and vu^T are matrices of size n x n that represent the outer product of u and v.

Ancient glaciation events are indicated by the presence of ridges of moraine, eskers, and drumlins.

Ancient glaciation events leave behind distinct landforms and sedimentary features that can be used to identify their occurrence. Some of these features include ridges of moraine, eskers, and drumlins.

Ridges of moraine: Moraines are accumulations of glacial debris, including rocks, sediments, and soil, that are deposited along the edges or surfaces of glaciers. Ridges of moraine can indicate the presence of ancient glaciers and their movement.

Eskers: Eskers are long, winding ridges of gravel and sediment that form underneath or within glaciers. They are created by the deposition of sediments by meltwater streams flowing through or beneath the ice. The presence of eskers suggests the past existence of glaciers.

Drumlins: Drumlins are elongated hills or mounds of glacial till that have a streamlined shape, with a steep side facing the direction of the glacial movement. They are formed by the deposition of sediments beneath the ice and can indicate past glaciation events.

Answer:

75%

Step-by-step explanation:

the equations of motion for the two masses x(t) and y(t) are:F1 = -k1x1F2 = -k1x2 + k2(y - x2)

Newton's second law of motion can be stated as F = ma (force equals mass times acceleration). In this question, we are looking for the equations of motion for the two masses x(t) and y(t) attached to the springs. We can use Newton's second law to derive the equations of motion for each mass.

First, we consider mass m1. The only force acting on this mass is the spring force from k1. We can apply Newton's second law to derive the equation of motion for this mass as:

F1 = -k1x1where F1 is the force exerted by the spring on mass m1, k1 is the spring constant, and x1 is the displacement of mass m1 from its equilibrium position. Next, we consider mass m2.

The spring force from k1 and the spring force from k2 act on this mass. We can apply Newton's second law to derive the equation of motion for this mass as:

F2 = -k1x2 + k2(y - x2)where F2 is the force exerted by the springs on mass m2, k1 and k2 are the spring constants, x2 is the displacement of mass m2 from its equilibrium position, and y - x2 is the displacement of the other spring from its equilibrium position.

Answer: 4.5 pounds

Explanation: To convert 72 ounces into pounds, we use the conversion factor for ounces and pounds which is 16 ounces = 1 pound.

Next, notice that we're going from a smaller unit, ounces, to a larger unit, pounds and when we go from a smaller unit to a larger unit, we divide. So here, we divide 72 by the conversion factor, 16, to get 4.5.

So 72 ounces equals 4.5 pounds.

What would a social psychologist call the story? The story is called a prime. A prime is what social psychologists would call the story that participants read right before the task of rating the danger of the object they were shown. A prime is something that influences the response of the main option in the experiment.

A prime, in this case, refers to the story that participants read before rating the danger of the object they saw. The study aims to analyze whether the story has an effect on how participants rated the danger of the objects that they saw.

The term social psychology refers to the scientific study of how people are affected by their social interactions, including how they think, feel, and behave in response to the social world around them.

The prime, in this case, refers to the story that participants read before rating the danger of the object they saw. A prime is an external stimulus that influences the response of the main answer in the experiment.

In this case, the story serves as a prime that potentially affects how the participants perceive the object as dangerous or harmless. The story serves as a prime that shapes the participant's rating of the object they saw.

The story, in this case, serves as an independent variable since it's the one being changed and tested to see if it affects the rating of the object's danger. The dependent variable, in this case, is the rating of the object's danger, since it is being influenced by the prime. The story primes have a direct effect on how participants rate the danger of the objects they are shown.

Consecuencia de 5^3 - 3 √(375 ÷ 3) + (7 + 2)^2 - 9^11 ÷ 9^9 es 91.46.

Potencias es una operación matemática para la multiplicación repetida de un número tanto como el rango. El rango de un número es un número que se escribe más pequeño y se ubica ligeramente hacia arriba. Basado en la semántica de escribir letras se llama superíndice, por ejemplo: 2², 3², 4³ y otros. En inglés, el exponencial se llama "potencia" o "exponente".

The answer to the question is that there are no points on the curve x3 + y3 = 9 in the xy-plane that have a tangent line that is horizontal.

The equation x3 + y3 = 9 is a cubic equation and is a non-linear equation. As such, it does not have any tangent lines that are horizontal. A tangent line is a line that just touches a point on a curve and has the same slope as the curve at that point. Since the equation is non-linear, the slope of the curve changes at each point, meaning that there cannot be any horizontal tangent lines.

To calculate the slope of the curve at any point (x,y), we use the formula m = (dy/dx) or m = 3*(x2/y2). At these points, the slope of the curve will not be zero, meaning that there is no horizontal tangent line at any point on the curve.

Therefore, the answer to the question is that there are no points on the curve x3 + y3 = 9 in the xy-plane that have a tangent line that is horizontal.

The part in the steering column that allows for changes in the angle between the upper and lower shafts is the universal joint.

The universal joint, also known as a U-joint or Cardan joint, is a mechanical device that enables changes in the angle between two shafts that are not in a straight line. In the context of a steering column, the upper and lower shafts are connected by a universal joint.

As the steering wheel is turned, it exerts rotational force on the upper shaft of the steering column. The universal joint allows for the transmission of this rotational motion while accommodating changes in the angle between the upper and lower shafts. It provides flexibility and compensates for any misalignment between the two shafts, ensuring smooth and continuous rotation of the steering column.

The universal joint typically consists of two yokes connected by a cross-shaped component with needle bearings. These bearings allow for rotation in multiple axes, allowing the steering column to handle variations in the angle between the upper and lower shafts during steering movements.

Answer:

96

Step-by-step explanation:

Let's assume that the marks needed in the next exam is \(x\). Then if the average becomes 90,

\(\frac{80 + 93 + 91 + x}{4}= 90\)

Now we can simply solve for \(x\):

⇒ \(\frac{264 + x}{4}= 90\)

⇒ \(264 + x = 360\)            [Multiplying both sides by 4]

⇒ \(x = 360 - 264\)            [Subtracting 264 from both sides]

⇒ \(x = \bf96\)

Therefore, you need to score 96 in your next exam to have an average of 90 on the four exams.

105

Answer:

Based on the information provided that one corner of the parallelogram measures 128 degrees, we can determine the measures of the other three angles x, y, and z.

In a parallelogram, opposite angles are congruent, which means that x and z are congruent to 128 degrees.

So, x = z = 128 degrees.

The sum of the measures of the interior angles of a parallelogram is always 360 degrees. Since x and z both measure 128 degrees, the sum of x and z is 2 * 128 = 256 degrees.

Therefore, we can find the measure of y by subtracting the sum of x and z from 360 degrees:

360 degrees - 256 degrees = 104 degrees

So, y measures 104 degrees.

To summarize:

x = z = 128 degrees

y = 104 degrees
