Answer:

La distancia desde el supermercado hasta la puerta del rascacielos es de 585,29 metros

Step-by-step explanation:

Dado que la altura del ático = 527 metros

El ángulo de elevación de la vista = 42 °

Tomamos la posición de la persona que ve el rascacielos en el supermercado, el ático del rascacielos y la base del rascacielos directamente frente a la persona, formando los vértices de un triángulo rectángulo ABC, respectivamente.

Por lo tanto;

AB = Línea de visión desde la persona hasta el ático.

BC = La altura del rascacielos = 527 metros

AC = La distancia desde el supermercado hasta la puerta del rascacielos.

De lo cual se nos da, ∠BAC = 42 °

Por lo tanto, ∠ACB = 90 ° y el ángulo de depresión desde el ático del rascacielos hasta la persona en el supermercado ∠ABC = 180 ° - 90 ° - 42 ° = 48 °

De la regla senoidal, tenemos;

\dfrac{BC}{sin(\angle BAC)} =\dfrac{527}{sin(42^{\circ})} = \dfrac{AC}{sin(\angle BAC))} = \dfrac{AC}{sin(48^{\circ})}

Lo que da;

AC = \dfrac{527 \times sin(48^{\circ}) }{sin(42^{\circ})}= 585.29 \ metros

Por lo tanto;

La distancia desde el supermercado hasta la puerta del rascacielos = 585,29 metros.

kenny6666 [7]
If it take  some x  minutes to upload  some y  digital photographs, it means it has an average of: x/y minutes to upload a single digital photograph. Then, to upload z photographs, you just multiply   x/y   by z.

Spoilers for answer:
If it take 7.2 minutes to upload 8 digital photographs, it means it has an average of: 7.2/8 = 0.9 minutes to upload a single digital photograph. This means that, by this rate, it will take 20 * 0.9 = 18 minutes to upload 20 photographs to the website.

Numbers that add to -0.5 and multiply to 1
Oliga [24]
Short Answer
There are two numbers
x1 = -0.25 + 0.9682i   <<<< answer 1
x2 = - 0.25 - 0.9582i   <<<< answer 2 
 
I take it there are two such numbers.
Let one number = x
Let one number = y

x + y = -0.5    
y = - 0.5 - x       (1)
xy = 1               (2)

Put equation 1 into equation 2
xy = 1
x(-0.5 - x) = 1
-0.5x - x^2 = 1               Subtract 1 from both sides.
-0.5x - x^2 - 1 = 0          Order these by powers
-x^2 - 0.5x -1 = 0           Multiply though by - 1
x^2 + 0.5x + 1 = 0         Use the quadratic formula to solve this.

\text{x = }\dfrac{ -b \pm \sqrt{b^{2} - 4ac } }{2a}

a = 1
b = 0.5
c = 1


\text{x = }\dfrac{ -0.5 \pm \sqrt{0.5^{2} - 4*1*1 } }{2*1}

x = [-0.5 +/- sqrt(0.25 - 4)] / 2
x = [-0.5 +/- sqrt(-3.75)] / 2
x = [-0.25 +/- 0.9682i

x1 = -0.25 + 0.9682 i
x2 = -0.25 - 0.9682 i

These two are conjugates. They will add  as x1 + x2 = -0.25 - 0.25 = - 0.50.

The complex parts cancel out.  Getting them to multiply to 1 will be a little more difficult. I'll do that under the check.

Check
(-0.25 - 0.9682i)(-0.25 + 0.9682i)
Use FOIL
F:-0.25 * -0.25 = 0.0625
O: -0.25*0.9682i
I: +0.25*0.9682i
L: -0.9682i*0.9682i = - 0.9375 i^2 = 0.9375

Notice
The two middle terms (labled "O" and "I" ) cancel out. They are of opposite signs.

The final result is 0.9375 and 0.0625 add up to 1
