The rephrased statement for Kun's proof is: A. In quadrilateral ABCD, if AB ≅ DC & AD ≅ BC, then AB║DC & AD║BC.

<h3>What is a Parallelogram?</h3>

A parallelogram is a quadrilateral that has two opposite sides that are congruent to each other and are also parallel to each other.

This means that if two pairs of opposite sides of a quadrilateral are congruent and parallel, then it is a parallelogram.

Rephrasing Kun's statement in his proof will therefore be: A. In quadrilateral ABCD, if AB ≅ DC & AD ≅ BC, then AB║DC & AD║BC.

A square of side length s lies in a plane perpendicular to a line L. One vertex of the square lies on L. As this square moves a

user100 [1]

Answer:

Part (A) The required volume of the column is $s^2h$ .

Part (B) The volume be $s^2h=\frac{s^2h}{2}+\frac{s^2h}{2}$ .

Step-by-step explanation:

Consider the provided information.

It is given that the we have a square with side length "s" lies in a plane perpendicular to a line L.

Also One vertex of the square lies on L.

Part (A)

Suppose there is a square piece of a paper which is attached with a wire through one corner. As you blow it up it spins around on the wire.

This square moves a distance h along L, and generate a corkscrew-like column with square.

The cross section will remain the same.

So the cross section area of original column and the cross section area of twisted column at each point will be the same.

The volume of the column is the area of square times the height.

This can be written as:

$s^2h$

Hence, the required volume of the column is $s^2h$ .

Part (B) What will the volume be if the square turns twice instead of once?

If the square turns twice instead of once then the volume will remains the same but divide the volume into two equal part.

$s^2h=\frac{s^2h}{2}+\frac{s^2h}{2}$

Hence, the volume be $s^2h=\frac{s^2h}{2}+\frac{s^2h}{2}$ .

A line is an undefined term because it. . contains an infinite number of points. . can be used to create other geometric shapes.

Veseljchak [2.6K]

The correct answer is statement number 3. A line is an undefined term because it describes something that does not have width or depth. However, lines can extend its length in both side infinitely. It contains arrowheads indicating it can extend.

Por término de temporada varias tiendas liquidan pantalones. Su precio de temporada era de $6. 990. Si quiero comprar tres panta

nlexa [21]

La tienda que ofrezca la mejor oferta por tres pantalones será aquella que tenga el mayor descuento de liquidación posible.

<h3>Análisis contextual de una pregunta incompleta</h3>

En este problema no es posible determinar cuántas tiendas existen ni los descuentos de liquidación ( $x$ ) correspondientes a cada uno y que todas las tiendas venden los pantalones al mismo precio de temporada ( $C$ ).

Las condiciones <em>matemáticas</em> de cada variable es:

$C = 6990$ (1)

$x \in$ $[0, 1)$ (2)

$n = 3$ (3)

La fórmula matemática para el precio final ( $C'$ ), en pesos, es la siguiente:

$C' = 3\cdot (6990)\cdot (1-x)$ (4)

Consideremos el caso de $N$ tiendas, cada una con un descuento de liquidación por cada pantalón y que ese descuento es aplicable a la compra de tres pantalones, entonces la tienda que ofrezca la mejor oferta por tres pantalones será aquella que tenga el mayor descuento de liquidación posible. $\blacksquare$
