Porfavor: Elabora un problema matemático relacionado con tu vida cotidiana donde utilices “adición y sustracción de números con signo” y el resultado sea - 9

Answers

Answer:

Queremos hacer un problema donde tengamos adición (a + b) y substracción ( a - b) de números con signo, de tal forma que el resultado final sea 9.

El caso más simple para este tipo de problemas es algo como:

"Vas a un mercado a comprar un par de productos, el producto A cuesta $A, y el producto B cuesta $B, si solo tenés un billete de $C, cuanto será el vuelto?"

Bueno, el vuelto va a ser la diferencia entre lo que vos entregáis, $C, y el costo total de los productos que compras ($A + $B)

Entonces el vuelto va a ser:

vuelto = $C - ($A + $B)

Y queremos que el resultado de este problema sea 9, entonces podemos escribir:

vuelto = $9 = $C - ($A + $B)

Ahora debemos encontrar los valores de las incógnitas.

Podemos simplemente definir dos de ellas y encontrar la tercera, por ejemplo si $C = $20 y $A = $2, entonces:

$9 = $20 - ($2 + $B)

$9 = $20 - $2 -$B

$9 = $18 - $B

$9 - $18 = -$B

-$9 = -$B

Entonces $B será = $9.

Y el problema podría escribirse como:

"Vas a un mercado a comprar un par de productos, el producto A cuesta $2, y el producto B cuesta $9, si solo tenés un billete de $20, cuanto será el vuelto?"

Consider a circle whose equation is x2 + y2 – 2x – 8 = 0. Which statements are true? Select three options.



The radius of the circle is 3 units.

The center of the circle lies on the x-axis.

The center of the circle lies on the y-axis.

The standard form of the equation is (x – 1)² + y² = 3.

The radius of this circle is the same as the radius of the circle whose equation is x² + y² = 9.

Answers

Answer:

The first, second, and fifth statements are correct.

Step-by-step explanation:

We are given a circle with the equation:

[tex]x^2+y^2-2x-8=0[/tex]

And we want to select the statements that are true.

First, we can convert the equation into standard form. We can group each variable:

[tex](x^2-2x)+(y^2)=8[/tex]

And complete the square for the first term:

[tex](x^2-2x+1)+(y^2)=8+1[/tex]

Factor and simplify:

[tex](x-1)^2+y^2=9[/tex]

We can rewrite our equation as:

[tex](x-(1))^2+(y-(0))^2=(3)^2[/tex]

So, this tells us that we have a circle centered on (1, 0) with a radius of 3 units.

In this case, the first statement, second statement (the point (1,0) is on the x-axis), and fifth statements are correct (the square root of 9 is also 3).

Answer:

The first, second, and fifth statements are correct.

The diameter of the circle shown below is 12 m. What is the area of the circle?

Answers

Answer:

36pi meters squared

Step-by-step explanation:

The area of a square is calculated using the formula "pi(r)^2" To find the radius (r), we divide the diameter by 2 (12/2=6). We know that the radius is six and 6^2 = 36. The last step is to multiply by pi.
