In Antigone Why does Teiresias come to see Creon?

Distancia (en metros) que recorre un proyectil disparado desde un avión de combate, se puede describir según la función: () = 8,

Stella [2.4K]

Answer:

a) La rapidez instantánea del proyectil a los 3,7 segundos de ser disparado es de 42,492 metros por segundo.

b) La aceleración instantánea del proyectil a los 4,1 segundos de ser disparado es de 17,26 metros por segundo al cuadrado.

Explanation:

El enunciado está incompleto puede prestarse a confusión, la forma correcta del mismo se presenta a continuación:

La distancia en metros que recorre un proyectil disparado desde un avión de combate se puede describir según la función $s(t) = 8,6\cdot t + 1,25\cdot t^{2} + 0,6\cdot t^{3}$ , donde $t$ son los segundos transcurridos desde el lanzamiento del proyectil. a) ¿Cuál es la rapidez instantánea del proyectil a los 3,7 segundos de ser disparado? b) ¿Cuál es su aceleración instantánea a los 4,1 segundos de ser disparado?

a) La rapidez instantánea del proyectil, en metros por segundo, es la primera derivada de la función distancia con respecto al tiempo, es decir:

$v(t) = \frac{ds(t)}{dt} = 8,6 + 2,50\cdot t + 1,8\cdot t^{2}$ (1)

Si sabemos que $t = 3,7\,s$ , entonces la rapidez instantánea del proyectil a los 3,7 segundos de ser disparado es:

$v(3,7\,s) = 8,6 + 2,50\cdot (3,7\,s) + 1,8\cdot (3,7\,s)^{2}$

$v(3,7\,s) = 42,492\,\frac{m}{s}$

La rapidez instantánea del proyectil a los 3,7 segundos de ser disparado es de 42,492 metros por segundo.

b) La aceleración instantánea del proyectil, en metros por segundo al cuadrado, es la segunda derivada de la función distancia con respecto al tiempo, es decir:

$a(t) = \frac{dv(t)}{dt} = \frac{d^{2}s(t)}{dt^{2}} = 2,50 + 3,6\cdot t$ (2)

Si sabemos que $t = 4,1\,s$ , entonces la aceleración instantánea del proyectil a los 4,1 segundos de ser disparado es:

$a(4,1\,s) = 2,50 + 3,6\cdot (4,1\,s)$

$a(4,1\,s) = 17,26\,\frac{m}{s^{2}}$

La aceleración instantánea del proyectil a los 4,1 segundos de ser disparado es de 17,26 metros por segundo al cuadrado.

Can you help me make up a story about my character that says? You are a 27-year-old devout nun who enjoys rock climbing?

Aleksandr-060686 [28]

Answer:

Explanation:

The best-known citizen of the Indian hill town of Darjeeling, Tenzing Norkay, is in residence now, though unseasonably, for the year’s climbing in the Himalayas has begun and most of his Sherpa colleagues are off helping Westerners up the peaks. His presence reflects the change that has taken place in his affairs since May 29th of last year, when he and Edmund Hillary stood on the summit of Mount Everest. That feat earned Tenzing a rest from his career as a climber, which had been arduous, and plunged him into a new career, involving contracts, publicity, and politics, which is a good deal more lucrative but which puts him under another kind of strain. Not only is he, like many famous men, unschooled in the ways of publicity but he deals haltingly with English, its lingua franca. Just keeping track of his own life, therefore, demands hard concentration. Tenzing complains that he has lost twenty-four pounds since climbing Everest, and he says—though he probably doesn’t mean it—that if he had foreseen the results, he would never have made the climb. His troubles are compounded by an element of jealousy in Darjeeling—he is to some extent a prophet without honor in his own country—and by a public disagreement, which he is well aware of, as to whether he is a great man or only an able servant. “I thought if I climbed Everest whole world very good,” he said recently. “I never thought like this.”

Tenzing is at everyone’s disposal. He has fixed up a small museum in his Darjeeling flat, exhibiting his gear, trophies, and photographs, and he stands duty there from ten in the morning to four-thirty in the afternoon. He is a handsome man, sunburned and well groomed, with white teeth and a friendly smile, and he usually wears Western clothes of the Alpine sort—perhaps a bright silk scarf, a gray sweater, knee-length breeches, wool stockings, and thick-soled oxfords. These suit him splendidly. Redolent with charm, Tenzing listens intently to questions put to him, in all the accents of English, by tourists who come to look over his display, and answers as best he can, often laughing in embarrassment. He charges no admission fee, but has a collection box for less fortunate Sherpa climbers, and he seems to look on the ordeal as a duty to the Sherpas and to India as a whole. The other day, I, who have been bothering him, too, remarked on the great number of people he receives. “If I don’t,” he answered, “they say I am too big.” And he scratched his head and laughed nervously.
