Answer:

≈451.37 cm³

Step-by-step explanation:

Since the diameter of the can is 6, the radius is 3.

Old can height: 12

Old can base radius: 3

Old can volume: 339.12 cm³

New can height: 12×1.1=13.2

New can base radius: 3×1.1=3.3

New can volume: 13.2×3.14×3.3²=13.2×3.14×10.89=451.36872 cm³

Una escalera de 131313 metros está recargada contra una pared cuando su base empieza a resbalar. Cuando la base está a 121212 me
Artyom0805 [142]

Answer:

El ángulo entre el piso y la escalera está cambiando a una razón de -1 radian por segundo.

Step-by-step explanation:

Sea x la distancia horizontal entre la pared y la base de la escalera y l la longitud de la escalera, medidas en metros. Además, tenemos que \theta es el ángulo entre la escalera y el piso, medido en radianes.

Si la pared y el piso son ortogonales entre sí, entonces podemos utilizar la siguiente relación trigonométrica que relaciona las variables anteriores:

\cos \theta = \frac{x}{l}  (1)

Por diferenciación implícita y la definición de razón de cambio tenemos que:

-\sin \theta \,\dot \theta = \frac{\dot x}{l} (2)

Donde:

\dot x - Razón de cambio de la distancia horizontal entre la pared y la base de la escalera, medida en metros por segundo.

\dot \theta - Razón de cambio del ángulo entre el piso y la escalera, medida en radianes por segundo.

Pero tenemos que el seno del ángulo está definido por:

\sin \theta = \frac{\sqrt{l^{2}-x^{2}}}{l} (3)

Si aplicamos (3) en (2), expandimos la ecuación como sigue:

-\frac{\sqrt{l^{2}-x^{2}}}{l}\,\dot \theta = \frac{\dot x}{l}

\dot \theta = - \frac{\dot x}{\sqrt{l^{2}-x^{2}}} (4)

Si tenemos que \dot x = 5\,\frac{m}{s}, l = 13\,m y x = 12\,m, entonces la razón de cambio del ángulo es:

\dot \theta = -\frac{\left(5\,\frac{m}{s} \right)}{\sqrt{(13\,m)^{2}-(12\,m)^{2}}}

\dot \theta \approx -1\,\frac{rad}{s}

El ángulo entre el piso y la escalera está cambiando a una razón de -1 radian por segundo.

I need help with this one
zheka24 [161]

Answer:

horizontal asymptote of y = -7

Step-by-step explanation:

The parent function is shown on the coordinate plane. The graph of the parent function has a horizontal asymptote (an imaginary line that the graph approaches, but never touches or intersects) of y = 0.

Since the function of g(x) = e^x - 7 is the graph of the parent function translated 7 units down, the function would have a horizontal asymptote of y = -7.
