f(x) = x² - 2x - 7

f(-1), this means that x = -1.

Since you need to find f(-1), substitute/plug in -1 into "x" in the function:

f(x) = x² - 2x - 7       Plug in -1 into "x"

f(-1) = (-1)² - 2(-1) - 7

f(-1) = 1 + 2 - 7

f(-1) = -4          Your answer is B

El angulo de elevacion del sol es de 29°12'35''. Calcular la longitud de la sombra proyectada por un hombre de 1,75m de estatura
Bingel [31]

Respuesta:

3,59 metros

Explicación paso a paso:

Conversión del ángulo de elevación a grados;

29 ° 12 '35 "

= 29 ° + 12 '/ 60 + 35 "/ 3600

= 29,20972 °

Resolviendo el triángulo de solución adjunto:

La longitud de la sombra se puede obtener utilizando la relación trigonométrica;

Sin θ = opuesto / hipoteno

Sin 29.20972 = 1.75 / sombra

Sombra = 1.75 / Sin 29.20972

Longitud de la sombra = 3,59 m
