Expand and simplify 5(2p-3)-2(2+3p)

1 answer:

6 0

4p-19
You need to distribute the 5 first then the -2
you will get 10p-15-4-6p
then all you need to do is combine like terms to get 4p-19

Distinguish between an axoim and a theorem

Anton [14]

Answer:

An axiom is often a statement assumed to be true for the sake of expressing a logical sequence. ... These statements, which are derived from axioms, are called theorems. A theorem, by definition, is a statement proven based on axioms, other theorems, and some set of logical connectives.

Step-by-step explanation:

I think this is right, but don't quote me on this.

How do you solve a problem involving squeeze theorem?

nadezda [96]

Answer:

Step-by-step explanation:

if two functions are squeezed together at a particular point , then any function trapped between them will get squeezed to that point. the squeeze theorem deals with limit value , rather than function value. the squeeze theorem sometimes called Pinch Theorem.

Una persona camina 7 kilómetros hacia el norte, después 3 kilómetros hacia el este y, luego, 3 kilómetros hacia el sur. ¿A qué d

qaws [65]

Answer:

La persona está a 5 kilómetros con respecto al punto de partida.

Step-by-step explanation:

Considérese que la dirección norte coincide con el semieje +y y que la dirección este coincide con el semieje +x. A continuación, obtenemos las formas vectoriales equivalentes de cada afirmación:

(i) Una persona camina 7 kilómetros hacia el norte:

$\vec r_{1} = 7\,\hat{j}\,[km]$

(ii) Después 3 kilómetros hacia el este:

$\vec r_{2} = 3\,\hat{i}\,[km]$

(iii) Y luego, 3 kilómetros hacia el sur:

$\vec r_{3} = -3\,\hat{j}\,[km]$

El vector resultante de desplazamiento se construye a partir de la siguiente suma de vectores:

$\vec R = \vec r_{1}+\vec r_{2} + \vec r_{3}$ (1)

$\vec R = 3\,\hat{i} + 4\,\hat{j}\,[km]$

Asumiendo que la distancia coincide con el desplazamiento resultante, calculamos la distancia con respecto al punto de partida mediante el Teorema de Pitágoras:

$\|\vec R\| = \sqrt{3^{2}+4^{2}}$

$\|\vec R\| = 5\,km$

La persona está a 5 kilómetros con respecto al punto de partida.
