Here is a square inscribed in a circle with radius 1 meter. What is the perimeter of

Dimas [21]

Answer:

$4\sqrt{2}$

Step-by-step explanation:

distance formula: $\sqrt{\left(x_2-x_1\right)^{2}+\left(y_2-y_1\right)^{2}}$

set square to be centered on the origin and find the distance between 2 of the connected points

$\sqrt{\left(3-2\right)^{2}+\left(2-1\right)^{2}}$

= $\sqrt{\left(1\right)^{2}+\left(1\right)^{2}}$

= $\sqrt{2}$

multiply by 4 as it is a square and all of its sides are equal

$4\sqrt{2}$

insert units

$4\sqrt{2}\ \ meters$

¿Cuáles son los procedimientos a ambos lados de la igualdad que se deben realizar para calcular el valor de la incógnita x en la

PilotLPTM [1.2K]

Answer:

Los procedimientos que se deben realizar para calcular la incógnita x en la ecuación 2x+5=7 son:

El 5 que está sumando a la izquierda del igual, se pasa a restar a la derecha del igual.
El 2 que multiplica a x a la izquierda del igual, se pasa a dividir a la derecha del igual.

Step-by-step explanation:

Siguiendo los procedimiento descritos en la respuesta, para calcular el valor de la incógnita:

2x + 5 = 7

Seguimos el primer paso: el 5 que está sumando a la izquierda del igual, se pasa a restar a la derecha del igual:

2x = 7 - 5

Seguimos el segundo paso: el 2 que multiplica a x a la izquierda del igual, se pasa a dividir a la derecha del igual:

$x=\frac{7-5}{2}$

Como puedes ver, así se despejaría la incógnita x y solo faltaría operar los datos en la ecuación para obtener la respuesta:

$x=\frac{2}{2}$
$x=1$

El resultado que nos daría la incógnita x sería 1. Podemos probar el resultado en la ecuación original para comprobar el resultado que obtuvimos:

2x + 5 = 7
2 *(1) + 5 = 7
2 + 5 = 7
7 = 7

Así, identificamos que los procesos realizados fueron correctos.

Which is the graph of g(x)=10/x

crimeas [40]

Answer:

Check the attached graph

Step-by-step explanation:

Given equation is $g\left(x\right)=\frac{10}{x}$ .

Now we need to graph the given equation $g\left(x\right)=\frac{10}{x}$ ..

Clearly it is not linear as equation is not of the form $y=mx+b$ . So we need to find some points on given equation $g\left(x\right)=\frac{10}{x}$ . by plugging some random values of x like -5,-3,1,... etc.

for x=-5, we get:

$g\left(x\right)=\frac{10}{x}$

$g\left(-5\right)=\frac{10}{-5}=-2$ .

Hence first point is at (-5,-2). Similarly we can find more points and graph those points.

x can't be 0 as division by 0 is not defined so it will have vertical asymptote at x=0.

Since degree of numerator is less than degree of denominator so y=0 will be horizontal asymptote.

Now join those points by a curved line to get final graph.

A) You want to buy a new sweatshirt. They normally cost 28.80, but you found one that's on sale for 40% off its normal price. Ho

arlik [135]

For question A, the answer is 2. Since the sale sweatshirt if 40% LESS, this means that 60% of the original price still remains. 28.80 x .60 = 17.28

For question B, the answer if 4. You can divide 17 by 20 getting .85
