how do you solve 5/13y+25=0

The option A is correct

In other words, the amount of heat entering the system must be greater than the amount of mechanical effort leaving the system.

Recall the first law of thermodynamics' ideas in order to comprehend this.

dQ = dU + dW

Assuming perfect conditions. There is no heat loss outside. No matter how much heat we give the gas dQ , some of it will be utilised to boost the gas's internal energy while the rest will be used to produce work. This must be less than dQ in turn.

Because of this extremely fundamental characteristic of all engines, none of them can operate at 100% efficiency. Even the "Carnot engine," the most ideal engine, is not entirely efficient.

The exact value for sin (∅) is √15/4 if  cos (∅)=-1/4 and ∅ is in the 3rd quadrant.

In mathematics, the trigonometric functions—also known as circle, angle, or goniometric functions—are real functions that connect the angle of a right-angled triangle to the ratios of its two side lengths.  As some of the most basic periodic functions, they are frequently employed in Fourier analysis to examine periodic phenomena.

The sine, cosine, and tangent are the trigonometric functions that are most commonly utilized in contemporary mathematics. The cotangent, secant, and their less common reciprocals, the cosecant, are each of their reciprocals.

Given, cos (∅)=-1/4 and ∅ is in the 3rd quadrant.

cos²∅+sin²∅=1

sin²∅=1-cos²∅

sin²∅=(1-(-1/4)²)

sin²∅=1-(1/16)

sin²∅=15/16

sin∅=√15/4

Therefore, the exact value for sin (∅) is √15/4 if  cos (∅)=-1/4 and ∅ is in the 3rd quadrant.

Calculating or estimating how likely or "possible" something is to occur is the subject of probability. Words like "certain," "impossible," or "probable" can be used to express the likelihood of an event occurring.              

                                             Probabilities in mathematics are always represented as fractions, decimals, or percentages with values ranging from 0 to 1.

P(2 or 3 jobs)=P(2 jobs)+P(3 jobs)-P(2 jobs and 3 jobs)=P(2 jobs) + P(3 jobs) since a student can not have 2 jobs as well as three jobs at a time.

(a) 794g of the initial sample will be left in the sample after 25 years. (b) Time taken to decay to half of its original amount is 3.39 years.

Isotopes(200g) are atoms that have the same number of protons in their nucleus, but a different number of neutrons. This means that they have the same atomic number, but a different atomic mass. Because of this, isotopes have different physical and chemical properties. Isotopes can be stable, meaning that they do not undergo radioactive decay, or they can be unstable, meaning that they will undergo radioactive decay over time.

(a) Substituting 25 for t in the expression, we get:

[tex]A(25) = 200e^{0.0541 \times 25}[/tex]

         [tex]= 200e^{1.3525}[/tex]

Thus, after 25 years, there will be

(b) We want to find t such that

[tex]A(t) = 200e^{0.0541}[/tex]

Solving for t, we get:

Dividing both sides by 200 and applying the natural logarithm to both sides, we get:

0.0541 × t = ln(0.5)

Contrary to a set, the same elements may appear more than once at various points in a sequence, and in contrast to a set, the order is important. The formal definition of a sequence is a function from natural numbers (the positions of the sequence's elements) to the elements at each position. A function from any index set is what is meant by an indexed family, which is a generalisation of the idea of a sequence.

(X=60,Y=47,Z=73),  the measures of the three angles.

When two rays are linked at their ends, they create an angle in geometry. The sides or arms of the angle are what are known as these rays.

When two lines meet at a point, an angle is created.

An "angle" is the measurement of the "opening" between these two rays. It is symbolized by the character.

The circularity or rotation of an angle is often measured in degrees and radians.

Angles are a common occurrence in daily life.

Angles are used by engineers and architects to create highways, structures, and sports venues.

According to our question

x+y+z=180

The second and third angles' combined measurements equal twice the first angle's combined measurement, therefore

y+z−2x+y+z=2=0

Third angle has 26 more degrees than second angle, therefore

z−y+z=y+26=26

As a result, we obtain the equation system.

x+y+z=180−2x+y+z=0−y+z=26

(1)(2)(3)

By removing y and z, use equations (1) and (2) to determine x. To get rid of y and z, multiply equation (2) by one before adding it to equation (1).

x+y+z2x−y−z3xx=180=0=180=60(4)

To get rid of z, use equations (1) and 3). To get rid of z, multiply equation (3) by 1 and then add it to equation (1).

x+y+zy−zx+2y=180=−26=154(5)

To determine, substitute x=60 into equation (5).

x+2y(60)+2y2yy=154=154=94=47

In order to find, we can now change x=60 and y=47 in equation (1).

x+y+z(60)+(47)+zz+107z=180=180=180=73

What is congruent triangles?

If and only if we can use rigid transformations to map one figure onto the other, then two figures are said to be congruent. All corresponding sides and angles are congruent because rigid transformations maintain distance and angle measure. Therefore, measuring all of the sides and angles of a pair of triangles would be one method of determining whether they are congruent.

Since reflexive angles means is an angle that is more than 180 degrees and less than 360 degrees.

And the reflexive sides means the reflexive property of congruence states that any shape is congruent to itself.

Vertical angles are angles opposite each other where two lines cross.

But to check the congruence of two triangles we only have the angles and sides of the two triangles are same.

It is a machine learning technique that teaches computers to carry out operations that comes naturally to humans: learn by example. Deep learning is a key technology behind driverless cars, enabling them to recognize a stop sign, or to distinguish a pedestrian from a lamppost. Deep learning networks learn by identifying intricate data structures in the data they experience. By developing computational models that are composed of multiple processing layers, the networks can create multiple levels of abstraction to represent the data. A layer is the highest-level building block in deep learning. A layer is a container that usually receives weighted input, transforms it with a set of functions through data processing and passes these values as output to the next layer.

Note: The question is incomplete. The complete question probably is: The layers, in deep learning, represent the data processing that occurs in order to achieve the correct output. select one: true false.
