To determine if a set of vectors in R3 is linearly dependent, we can inspect the vectors and see if any one of them can be expressed as a linear combination of the others. If so, the set is linearly dependent.

To determine whether a set of vectors in R3 is linearly dependent or not, we can inspect the vectors and see if any one of them can be expressed as a linear combination of the others.

For example, consider the set of vectors:

v1 = (1, 2, 3)

v2 = (2, 4, 6)

v3 = (1, 2, 5)

We can see that v2 is equal to 2v1, which means that it can be expressed as a linear combination of v1. Therefore, the set of vectors is linearly dependent.

In general, a set of vectors in R3 is linearly dependent if and only if one of the vectors can be expressed as a linear combination of the others. This is because any set of more than three vectors in R3 is necessarily linearly dependent, since the dimension of R3 is only three.

To determine if a differential form is exact, we need to check if its partial derivatives satisfy the condition of equality. If the differential form is not exact, we can multiply it by an integrating factor to make it exact.

Given a differential form of the form M(x, y)dx + N(x, y)dy, we can determine if it is exact by checking if ∂M/∂y = ∂N/∂x. If this condition is not satisfied, the differential form is not exact. However, we can multiply the differential form by an integrating factor to make it exact.

By multiplying the original differential form by an integrating factor, which is usually a function of either x or y, the resulting form will have equal partial derivatives, satisfying the condition for exactness. The integrating factor effectively "corrects" the form and makes it exact.

By finding the appropriate integrating factor and multiplying it with the given differential form, we can transform it into an exact form. This process is a fundamental technique in solving certain types of differential equations and allows us to find solutions that would otherwise be challenging to obtain.

In Economics, a country that has a lower opportunity cost of producing a certain product than another country is said to have a comparative advantage.

Deena has an absolute advantage in producing both goods, and a comparative advantage in producing sun dials would be the correct option. As shown in Table 1, Deena has a comparative advantage in producing sundials since her opportunity cost of producing one sundial is 0.5 wind chimes, while Artie's opportunity cost of producing one sundial is 1 wind chime. As a result, Deena has the lowest opportunity cost of producing sun dials.

The absolute advantage is the capability of an individual or a country to produce a good using fewer resources than another individual or country. Since Deena has a lower opportunity cost of producing both wind chimes and sundials, she has an absolute advantage in producing both goods. As a result, the correct option is "Deena has an absolute advantage in producing both goods, and a comparative advantage in producing sundials."

Answer:

x=0.5 or 1/2

Step-by-step explanation:

Answer:

See below.

Step-by-step explanation:

\(\frac{6z^2-12z}{4z^2-16z+16} +\frac{3z}{z^2-z-2} \\\\\)

First, factor the numerators and the denominators:

\(=\frac{6z(z-2)}{4(z^2-4x+4)}+\frac{3z}{z^2-z-2}\\=\frac{6z(z-2)}{4(z-2)^2}+\frac{3z}{(z-2)(z+1)}\\=\frac{3z}{2(z-2)}+\frac{3z}{(z-2)(z+1)}\)

Now, make the two denominators equivalent. To do this, we can multiply the first term by (z+1) and multiply the second term by 2. This will give us:

\((\frac{z+1}{z+1} )(\frac{3z}{2(z-2)})+(\frac{2}{2})(\frac{3z}{(z-2)(z+1)})\\=\frac{3z(z+1)}{2(z-2)(z+1)}+\frac{6z}{2(z-2)(z+1)} \\\)

Now, combine them since they have a common denominator:

\(=\frac{3z^2+3z+6z}{2(z-2)(z+1)}\\ =\frac{3z^2+9z}{2(z-2)(z+1)} \\=\frac{3z(z+3)}{2(z-2)(z+1)}\)

This cannot be simplified further.

The relative price is a useful measure for comparing the prices of different products or services, especially in the context of consumer preferences and demand.

Relative price refers to the price of a particular product or service in relation to other goods or services in the market.

It is calculated as the ratio of the price of a given product or service to the price of a reference product or service, commonly referred to as a base good or service.

Let the price of a pair of shoes be $5 and the price of a box of tea be $3.

Then the relative price of a pair of shoes is given by:

Relative price of shoes = Price of shoes / Price of tea

= $5 / $3

= 1.67

Thus, the relative price of a pair of shoes is 1.67.

Similarly,

The relative price of a box of tea can be calculated as follows:

Relative price of tea = Price of tea / Price of shoes

= $3 / $5

= 0.6

Therefore, the relative price of a box of tea is 0.6.

This means that the price of tea is relatively cheaper than that of shoes, as its relative price is less than one.

The relative price of shoes is greater than one, which indicates that shoes are relatively more expensive than tea.

Based on the speed that light travels and the distance around the Earth along the Equator, the number of times the space ship would travel in 1 second is 0.133 times

The number of times that the space ship would travel around Earth around the Equator, going at the speed of light is:

= Distance around the Earth along the Equator / Speed of light

Solving for the number of times around the Earth for the space ship gives:

= 2.48×10⁴  / 1.86×10⁵

Teniendo en cuenta la definición de sistema de ecuaciones lineales, las edades de los hermanos son 15 y 23 años.

Un sistema de ecuaciones lineales es un conjunto de dos o más ecuaciones de primer grado, en el cual se relacionan dos o más incógnitas.

Resolver un sistema de ecuaciones consiste en encontrar el valor de cada incógnita para que se cumplan todas las ecuaciones del sistema. Es decir, se debe buscar los valores de las incógnitas, con los cuales al reemplazar, deben dar la solución planteada en ambas ecuaciones.

En este caso, se debe plantear un sistema de ecuaciones lineales teniendo en cuenta que:

Por un lado, las edades de dos hermanos suman 38 años. Esto se expresa mediante: x+y= 38

Por otro lado, la edad de uno es superior en 8 años a la edad del otro, expresado mediante x=y +8

Entonces, el sistema de ecuaciones a resolver es:

\(\left \{ {{x+y=38} \atop {x=y+8}} \right.\)

Existiendo diversos métodos para resolver un sistema de ecuaciones, se decide resolver mediante el método de sustitución, que consiste en despejar una de las dos variables en una de las ecuaciones del sistema y sustituir su valor en la otra ecuación.

En este caso, en la segunda ecuación la variable "x" ya se encuentra aislada. Entonces, reemplazando dicha expresión en la primer ecuación se llega a:

y +8 +y= 38

Resolviendo:

2y + 8=38

2y= 38 -8

2y=30

y=30 ÷2

y=15

Finalmente, para obtener el valor de y se reemplaza en la  segunda ecuación, y resolviendo se obtiene:

x= y + 8

x= 15 + 8

x=23

Finalmente, las edades de los hermanos son 15 y 23 años.

Given:

The equation is:

\(\dfrac{x+1}{x-1}-\dfrac{x-1}{x+1}=\dfrac{7}{12}\)

To find:

The value of x.

Solution:

Formulae used:

\((a+b)^2=a^2+2ab+b^2\)

\((a-b)^2=a^2-2ab+b^2\)

\((a-b)(a+b)=a^2-b^2\)

We have,

\(\dfrac{x+1}{x-1}-\dfrac{x-1}{x+1}=\dfrac{7}{12}\)

Taking LCM, we get

\(\dfrac{(x+1)^2-(x^2-1)^2}{(x-1)(x+1)}=\dfrac{7}{12}\)

\(\dfrac{x^2+2x+1-(x^2-2x+1)}{x^2-1^2}=\dfrac{7}{12}\)

On cross multiplication, we get

\(12(x^2+2x+1-x^2+2x-1)=7(x^2-1)\)

\(12(4x)=7x^2-7\)

\(48x=7x^2-7\)

\(0=7x^2-48x-7\)

Splitting the middle term, we get

\(7x^2-49x+x-7=0\)

\(7x(x-7)+1(x-7)=0\)

\((7x+1)(x-7)=0\)

\(x=-\dfrac{1}{7},7\)

Therefore, the values of x are \(-\dfrac{1}{7}\) and \(7\).

To find only one fake coin from 8 coins can be done in two weighings.

Divide the coins into three groups, A, B, and C, each consisting of three coins.

A and B are first weighed against one another. If the balancing scale is straight, fake coins belong in group C; otherwise, they belong in A or B, depending on which side of the scale is up.

Finding the lighter fake coin requires a second weighing if the first weighing indicates that the fake coins are in group C. Weigh any two phony coins from the group if A/B. The third coin is phony if the scale is balanced; else, choose the coin that is lighter.

For 3 weighing, make pair of 4 and followed by pair of 2 for the lighter group. At last, compare the last 2 coins to find the lighter coins.

Using the arc length formula, one may determine a circle's arc length given its radius and centre angle.

The length of the arc can be calculated using the formula for arc length given by;

Arc length = θ × r

Where θ is the central angle of the arc in radians, and r is the radius of the circle.

Substituting the values given in the problem,
