UNA ESCALERA ESTA RECARGADA EN LO ALTO DE UNA PARED DE 4 METROS Y SU BASE DESPEGADA A 3 METROS DE LA PERED ¿CUANTO MIDE LA ESCAL
Tatiana [17]

Answer:

La parte de las escalara desde el piso al borde de la barda es de 5.66 metros.

 

⭐Explicación paso a paso

Para resolver haremos uso de identidades trigonométricas. Nos apoyaremos a su vez en la imagen adjunta, en el cual podemos representar la situación como un triángulo rectángulo.

 

Cateto opuesto: 4 metros

Cateto adyacente: 4 metros

Hipotenusa: longitud de la escalera (l)

 

Por Pitágoras:

l² = 4² + 4²

l² = 16 + 16

l² = 32

l = √32

l = 4√2 m

l = 5.66 metros

Write a quadratic equation to represent the circle graphed on the right
Ivahew [28]

Answer:

<h2>The standard form: x² + (y + 1)² = 25</h2><h2>The general form: x² + y² + 2y - 24 = 0</h2>

Step-by-step explanation:

The equation of a circle:

(x-h)^2+(y-k)^2=r^2

(h, k) - center

r - radius

We have the center (0, -1) and the radius r = 5   <em>(look at the picture)</em>.

Substitute:

(x-0)^2+(y-(-1))^2=5^2\\\\x^2+(y+1)^2=25

<em>use (a + b)² = a² + 2ab + b²</em>

x^2+y^2+2y+1=25             <em>subtract 25 from both sides</em>

x^2+y^2+2y-24=0
