Answer:

La elevación de la carretera es de aproximadamente 0.999 metros.

Step-by-step explanation:

Cuando se dice que la pendiente es de 5 %, se quiere decir que la tangente del ángulo de elevación de la carretera es de 0.05. Trigonométricamente hablando, podemos calcular el ángulo de la pendiente como sigue:

\theta = \tan^{-1} 0.05

\theta \approx 2.862^{\circ}

La elevación de la carretera se determina mediante la función seno:

\sin \theta = \frac{h}{l} (1)

Donde:

h - Elevación de la carretera, medida en metros.

l - Longitud de la carretera, medida en metros.

Si sabemos que l = 20\,m y \theta \approx 2.862^{\circ}, entonces la elevación de la carretera es:

h = l\cdot \sin \theta

h \approx 0.999\,m

La elevación de la carretera es de aproximadamente 0.999 metros.

Olin [163]

I'm sorry, but I have to seriously question the whole process.

-- What does "the angle between the Earth and sun" mean?
-- How in the world does he measure the distance between the Earth and sun ?
-- How are either of these related to the distance between the Moon and Sun ?

To me, this "scientist's" methods are as defective as this question is.

y=3x-2  y=-2x+8

3x-2=-2x+8  (plus 2 each side)

3x=-2x+6     (plus 2x each side)

5x=6   (divide by 5 each side)

x=1.2

Plug x back into an equation

y=3(1.2)-2

y=3.6-2

y=1.6

Answer: (1.2, 1.6)

Find the arc length of the semicircle. 7the grade
charle [14.2K]

so, is a semi-circle, half a circle, recall a circle has a total of 360°, so half of that will be 180°.

the diameter of that circle is 10, so its radius is half that, or 5.


\bf \textit{arc's length}\\\\ s=\cfrac{\theta \pi r}{180}~~ \begin{cases} r=radius\\ \theta =angle~in\\ \qquad degrees\\[-0.5em] \hrulefill\\ \theta =180\\ r=5 \end{cases}\implies s=\cfrac{(180)(\pi )(5)}{180}\implies s=5\pi \stackrel{\pi =3.14}{\implies s=15.7}
