enot [183]

Answer:

La altura del globo con respecto al suelo es 449,6 metros.

Step-by-step explanation:

La afirmación está incompleta. El enunciado completo es: "Un globo vuela entre dos ciudades A y B, que distan entre sí 1.500 m. Los tripulantes del globo ven la ciudad A con un ángulo de depresión de 27°, mientras que para ver la ciudad B es de 36°. ¿Cuál es la altura aproximada del globo con respecto al suelo?

El diagrama geométrico de la situación se encuentra descrita en el archivo adjunto. La altura aproximada del globo puede obtenerse con ayuda de las funciones trigonométricas, en este caso, se recomienda utilizar la función tangente de los ángulos de depresión:

Ciudad A

\tan 27^{\circ} = \frac{h}{1500\,m-x}

0,510 = \frac{h}{1500\,m-x}

Ciudad B

\tan 36^{\circ} = \frac{h}{x}

0,727 = \frac{h}{x}

Donde h y x son la altura con respecto al suelo y la distancia horizontal con respecto a la ciudad A.

A continuación, se elimina la altura de ambas ecuaciones por igualación y se determina la distancia horizontal del globo con respecto a la ciudad A:

0,727\cdot x = 0,510\cdot (1500\,m-x)

1,237\cdot x = 765\,m

x = 618,432\,m

Finalmente, la altura del globo con respecto al suelo es:

h = 0,727\cdot x

h = 0,727\cdot (618,432\,m)

h = 449,600\,m

La altura del globo con respecto al suelo es 449,6 metros.

Solve the following exponential function 4^3x = 4^2
Alekssandra [29.7K]

For this case we must solve the following equation:

4^{3x} = 4 ^ 2

By definition, for the bases to be equal then the exponents must also be the same. Thus, we have to:

3x = 2

Dividing by 3 to both sides of the equation we have:

x = \frac {2} {3}

Answer:

x = \frac {2} {3}

3x + 2<br> Output (y)<br> Input (x)<br> 0 <br> 2<br> 4 but for x
seropon [69]

Answer:

so if x = 0, x = 2, and x = 4

3(0) + 2 = 0 + 2 = 2, so when x = 0, y = 2

3(2) + 2 = 6 + 2 = 8, so when x = 2, y = 8

3(4) + 2 = 12 + 2 = 14, so when x = 4, y = 14

Please help!! I’m struggling with this question in my quiz.
san4es73 [151]
If the formula is V= Ab x H

then the base and height is 4 and 7.5 because it doesn’t need to be the bottom so you multiply 7.5 x 4= 30 but we have to half it since it’s a triangle which is 15 and then multiply 10 which gives us 150 cm squared.
