Proofs

Proof means sufficient evidence to establish the truth of something. It is obtained from deductive reasoning, rather than from empirical arguments. Proof must show that a statement is true in all cases, without a single exception.

How do you work out 18 people as a percentage?

To have a meaningful answer, you need to have 18 people compared to another number of people. Otherwise, 18 people is simply 1800% people.

How to Prove that the equation tan z equals z has only real roots?

Well, honey, to prove that the equation tan z = z has only real roots, you gotta show that the function f(z) = tan z - z has no zeros with nonzero imaginary parts. One way to do that is by analyzing the behavior of f(z) on the real line and using the Intermediate Value Theorem. So, put on your thinking cap and get ready to dive into some complex analysis, darling.

Which larger shape would be made if the two sectins are fitted togethr?

Well, honey, if you slap those two sections together, you'd end up with one big ol' shape, now wouldn't you? It's like putting two puzzle pieces together to make a bigger picture. So, to answer your question, the larger shape would be a combination of the two sections fitting snugly side by side.

What are the conditions of lami's theorem?

Lami's theorem states that if three forces are in static equilibrium, then the magnitude of each force is proportional to the sine of the angle between the other two forces.

Since the forces are in static equilibrium, they sum to zero. This means that if the force vectors are put end-to-end, they form a triangle.

The "law of sines" applies to any triangle, and states that the length of each side is proportional to the sine of the opposite angle.

Interpreting the sides as force vectors, we get a statement of Lami's theorem.

How many hundred are there in 47621?

There are 47621/100 = 476.21 of them.

Which number is irrational -5.72?

There are no irrational numbers in the value -5.72. All of the components of the value are represented by rational numbers.

An irrational number is any number that cannot be represented by a fraction a/b where a and b are integers.

-5.72 itself is rational as it can be represented by -572 / 100.

The digits of the value are also rational as they can be represented as -5/1, 7/1 and 2/1, respectively.

What is a cube like?

A cube is a three-dimensional solid object bounded by six square faces, facets or sides, with three meeting at each vertex. The cube can also be called a regular hexahedron and is one of the five Platonic solids. It is a special kind of square prism, of rectangular parallelepiped and of 3-sided trapezohedron. The cube is dual to the octahedron. It has cubical symmetry (also called octahedral symmetry). A cube is the three-dimensional case of the more general concept of a hypercube, which exists in any dimension.

What are the congruence theorems or postulates?

They are theorems that specify the conditions that must be met for two triangles to be congruent.

What 2 groups of rock are formed from all 3 kinds of rock?

Technically all 3 can make up each Sedimentary, Metamorphic, and Igneous.

But the process of metamorphosis is really kinda of linear, and you can only metamorphose a Metamorphic further, so the answer to your question would really be:

Igneous and Metamorphic.

Here is the explanation of the Rock Cycle:

# Magma cools to form igneous rock after a volcanic event.

# Igneous rock undergoes weathering to form sediment. The sediment is taken somewhere and deposited. (i.e. the beach, delta, bottom of a body of water or in sand dunes). # The deposited sediment undergoes a the processes that turns it into a rock). (i.e. cementation (think of concrete hardening, but over a much longer period of time) and compaction.)

# As the Sedimentary rock becomes buried under more sediment, it goes deeper into the earth. The heat and pressure cause metamorphism to occur. This transforms the sedimentary rock into a Metam orphic rock. This can also happen by a force called Subduction. This happens when one tectonic plate rides up on the other, forcing the lower plate to be pushed deep into the earth. This will happen to the point where it melts and become Magma (see #1)

# As the metamorphic rock is buried more deeply (or as it is squeezed by increasing subduction depths), temperatures and pressures will keep rising. when the temperature becomes hot enough, the metamorphic rock melts. The molten rock once again magma. Thus finishing the cycle, starting back at #1.

Given that information. There are shortcuts.

# Any rock type can be weathered forming sediments, followed by transportation and deposition of the sediment. Metamorphic and Sedimentary rocks can also undergo weathering/erosion. 2. Igneous rocks can undergo metamorphism (with added heat and pressure) to become metamorphic rocks.

So Therefore,

Igneous rock can be eroded into sediments, Ultimately becoming Sedimentary rock. And it can also be metamorphosed by heat and pressure, becoming a Metamorphic Rock before being melted into Igneous.

Sedimentary Rock can also be eroded into sediments, Ultimately becoming another Sedimentary rock. And it can also be metamorphosed by heat and pressure, becoming a Metamorphic Rock before being melted into Igneous.

Metamorphic Rock can be eroded into sediments, Ultimately becoming Sedimentary rock. And it can also be metamorphosed farther by heat and pressure, becoming another type of Metamorphic Rock in the line before being melted into Igneous.

What is the formula of 2sinxcosx?

The formula for ( 2\sin(x)\cos(x) ) is equivalent to ( \sin(2x) ) using the double angle identity for sine function.

How the polygon of force obtained by experiment?

The polygon of forces can be obtained experimentally by applying multiple forces to an object and measuring their magnitudes and directions. By drawing vector representations of these forces to scale and closing the shape of the polygon, the resultant force can be determined. This method helps visualize the equilibrium or resultant force acting on the object.

Is bactometer a rapid testing or traditional testing method?

Technically it is a rapid test method- since it is based on the measurement of an endpoint that typically occurs earlier than the endpoint of a classical micro method, which of course is the visual detection of growth - seen either as turbidty or colonies by the human eye. It does however have some ties to classical methods- it still is growth based.

How much difference is there between a centi unit and a milli unit?

SI prefixes, also known as a metric prefixes, are names or associated symbols that precedes a unit of measure or its symbol to form decimal multiples or submultiples. SI prefixes are used to reduce the quantity of zeroes in numerical equivalencies.

What are the difference between package unit and split unit?

A package unit contains all elements of the refrigeration cycle in one system. The 4 major components include: A compressor, condenser, metering device, and a evaporator. All elements are needed to complete the cycle of refrigeration.

As for a split unit, All elements of the refrigeration cycle are used, however the condenser is located outside of the facility, while the evaporator is located inside of the facility.

To better understand the difference in question, you must understand the job of each component in the refrigeration cycle. For example, a condenser is normally used to reject heat or cold air from a building, while a evaporator normally supplies heat or cold air to the building.

What is H U C A in World War 2?

The acronym "HUCA" refers to the "House Un-American Activities Committee" (also known as the House Committee on Un-American Activities), a committe of the U.S. House of Representatives. For Wikipedia's article on this subject, see: http://en.wikipedia.org/wiki/House_Un-American_Activities_Committee.

Examples of taboo?

In some cultures, taboo topics can include discussing death, sex, or certain religious beliefs. Certain foods may also be considered taboo, such as pork in Islam or beef in Hinduism. Taboos can vary widely between different societies and can be influenced by religion, traditions, or superstitions.

What does an equal sign mean in proof reading?

A proof is often in the form of a sequence of statements (in common, precise language or "math language"). If an "equals sign" appears, it is probably part of a statement. If so, it means, as expected, equals.

What does a circle with a diagonal line through it mean?

If you mean a zero with a diagonal line through it, it is the symbol for the empty set which is the set that contains nothing.

One or two or more whole numbers that are multiplied to get a product?

There is no specific name.

For example, (-2)*(-3) = +6 but there is no special name for -2 and -3.
