## What Is K In Geometry

Since k is constant , we can find k when given any point by dividing the y-coordinate by the x-coordinate. For example, if y varies directly as x, and y = 6 when x = 2, the constant of variation is k = = 3. Thus, the equation describing this direct variation is y = 3x.

## What Is K In Algebra 2

When listing the dimensions of a matrix, give the number of rows followed by the number of columns. direct variation a relationship in which the ratio between two variables is constant. If k = y x or y = kx, where k is a non-zero constant, then y varies directly with x.

**What does K stand for in pre algebra?**

constant. In the context if a math problem you would encounter in school k would be used to represent a constant you have to find the value of, usually when x and y are already used to represent a function. In formulas such as a^kt for interest k represents an arbitrary value.

## What Is Constant Of Proportionality

Constant of proportionality is the constant value of the ratio between two proportional quantities. Two varying quantities are said to be in a relation of proportionality when, either their ratio or their product yields a constant. The value of the constant of proportionality depends on the type of proportion between the two given quantities: Direct Variation and Inverse Variation.

**Direct Variation:**The equation for direct proportionality is y = kx, which shows as x increases, y also increases at the same rate. Example: The cost per item is directly proportional to the number of items purchased, expressed as y x**Inverse Variation:**The equation for the indirect proportionality is y = k/x, which shows that as y increases, x decreases and vice-versa. Example:The speed of a moving vehicle inversely varies as the time taken to cover a certain distance, expressed as y 1/x

In both the cases, k is constant. The value of this constant is called the coefficient of proportionality. The constant of proportionality is also known as unit rate.

## Graphs Of Constant Functions

You may be wondering how a constant function would look like on a coordinate plane. If you’ve ever seen a horizontal line in the graph, then what you’ve seen is the graph of a constant function. A constant function refers to a real-valued function with no variable in its definition. Let us consider the constant function f = 3 where f: R R.

- This means that it will always generate an output equal to 3, no matter what input values we provide
- So some points on its graph can be , , , etc.

Let us see the graph of the constant function f = 3 below.

So the graph of f = 3 is a horizontal line as the y-coordinates of all points are the same . Hence, the graphs of all constant functions are horizontal lines.

## Can We Solve Like And Unlike Terms If Yes Then How

*Yes, you can solve like and unlike terms.*

Moreover, it is quite easy to solve the like and unlike terms. But before solving them, you must remember what is term in math. This will help you to solve terms with ease.

So, lets check how to analyze terms in algebraic equations.

Suppose you and your other 10 friends went to a restaurant to eat some snacks. And all of you gave the order as :

- 1 ordered: Hamburger

You can see three similar or like snacks: Hamburger, French Fries, and Soft drinks. Now, you can separate them as like and unlike terms.

The unlike terms are Hamburger, French Fries, and Soft drinks.

The equation can be written as:

*=> **2h**+**f**+**d**+**3h**+**2f**+**2d*

Simplify it as:

## Why Do We Use The Constant Of Proportionality

We use constant of proportionality in mathematics to calculate the **rate of change** and at the same time determine if it is direct variation or inverse variation that we are dealing with. Let us assume that the cost of 2 apples = $20. We determine that the cost of 1 apple = $10. We have found the Constant of Proportionality for the cost of an apple is 2.

If we want to draw a picture of the Taj Mahal by sitting in front of it on a piece of paper by looking at the real image in front of us, we should maintain a proportional relationship between the measures of length, height, and width of the building. We need to identify the constant of proportionality to get the desired outcome. Based on this, we can draw the monument with proportional measurements. For instance, if the height of the dome is 2 meters then in our drawing we can represent the same dome with height 2 inches. Similarly, we can draw other parts. In such scenarios, we use constant of proportionality.

Working with proportional relationships allows one to solve many real-life problems such as:

## Slope Of A Constant Function

A constant function is a linear function whose general format is y = mx + k, where m and k are constants. Thus, a constant function which is f = k y = k can be written as y = 0x + k. Comparing this equation with the slope-intercept form y = mx+b, we get its slope to be m = 0. Thus, the slope of a constant function is 0.

## How To Solve The Constant Of Proportionality

We apply our knowledge on the direct and inverse variations, identify them and then determine the constant of proportionality and thereby get the solutions to our problems.

**Example 1:**Find the constant of proportionality, if y=24 and x=3 and y x.

Solution: We know that y varies proportionally with x. We can write the equation of the proportional relationship as y = kx. Substitute the given x and y values, and solve for k.

24 = k

**Important notes**

- To check if the 2 quantities are proportional or not, we have to find the ratio of the two quantities for all the given values. If their ratios are equal, then they exhibit a proportional relationship. If all the ratios are not equal, then the relation between them is not proportional.
- If two quantities are proportional to one another, the relationship between them can be defined by y = kx, where k is the constant ratio of y-values to corresponding x-values.
- The same relationship can also be defined by the formula x=y, where 1/k is now the constant ratio of x-values to y-values.

## Characteristics Of A Constant Function

All the constant functions cut through the vertical axis as per the value of their constant and they do not cut through the horizontal axis, as they are parallel to it. Also, the constant functions are continuous as they represent horizontal lines that extend continuously on both sides without any break. Here are some of the important characteristics of a constant function:

## Applications Of Algebraic K

The earliest application of algebraic *K*-theory to topology was Whitehead’s construction of Whitehead torsion. A closely related construction was found by C. T. C. Wall in 1963. Wall found that a space dominated by a finite complex has a generalized Euler characteristic taking values in a quotient of *K*0, where is the fundamental group of the space. This invariant is called *Wall’s finiteness obstruction* because *X* is homotopy equivalent to a finite complex if and only if the invariant vanishes. Laurent Siebenmann in his thesis found an invariant similar to Wall’s that gives an obstruction to an open manifold being the interior of a compact manifold with boundary. If two manifolds with boundary *M* and *N* have isomorphic interiors , then the isomorphism between them defines an *h*-cobordism between *M* and *N*.

Whitehead torsion was eventually reinterpreted in a more directly *K*-theoretic way. This reinterpretation happened through the study of *h*-cobordisms. Two *n*-dimensional manifolds *M* and *N* are *h*-cobordant if there exists an -dimensional manifold with boundary *W* whose boundary is the disjoint union of *M* and *N* and for which the inclusions of *M* and *N* into *W* are homotopy equivalences . Stephen Smale‘s *h*-cobordism theorem asserted that if *n* 5, *W* is compact, and *M*, *N*, and *W* are simply connected, then *W* is isomorphic to the cylinder *M*× . This theorem proved the Poincaré conjecture for *n* 5.

## Applications And Open Questions

Algebraic *K*-groups are used in conjectures on special values of L-functions and the formulation of a non-commutative main conjecture of Iwasawa theory and in construction of higher regulators.

Parshin’s conjecture concerns the higher algebraic *K*-groups for smooth varieties over finite fields, and states that in this case the groups vanish up to torsion.

Another fundamental conjecture due to Hyman Bass says that all of the groups *Gn* are finitely generated when *A* is a finitely generated **Z**-algebra. are the *K*-groups of the category of finitely generated *A*-modules)
