These days sees the best new group from Pandora to get 2018, when using the launch in the Valentine’s Day and CNY jewelry! As is actually traditional, this really is only a smaller release, but the item manages to help pack in numerous different types. As properly as jewellery for your Moments selection, there will also be new products for Pandora Went up, Essence as well as Floating Locket petites! Today sees the primary new collection from Pandora intended for 2018, when using the launch in the Valentine’s Morning and CNY jewelry! As can be traditional, this really is only a smaller release, nevertheless it manages for you to pack in pandora uk sale a range of several pieces. In addition to jewellery for the Moments assortment, there can also be new lines for Pandora Increased, Essence as well as the Floating Locket petites!

As usual, stores happen to be uploading a considerable number of live game to social media, which offers us an improved idea with what many of the beads appear to be in man. The heart-key jewellery looks sensitive and POST particularly like the heart-shaped Suspended Locket. The heart-lock bracelet is also cute, but I’m however surprised by simply how significant the clasp is due to person, it’s definitely a content article you may wear which has no beads upon it. Actually, I speculate how it'd suit being filled up pandora necklaces like an effective charm bracelet. You will find two new designs establishing in celebration belonging to the Lunar Brand new Year today! One is an extremely traditional Pandora CNY design and style the Chance & Fortune charm.

The Double Enjoyment is far more contemporary in style. For the full preview regarding both necklaces, have a peek through this Pandora CNY 2018 tag. These lovely live pictures from Patty show off the brand-new beads properly. The Fortune & Bundle dangle is definitely as rather as I hoped it would! I don’t understand if I’ll understand it straightaway even though, I might loose time waiting for a promo, seeing while I’ve spent my pennies during the various sales. The Two bottle Happiness dangle is known for a nice color of teeth enamel, but I'd have recommended it without the pave detailing. The appear of enamel colour against pandora disney uk bright silver might have been lovely on its own. It’s the entire year of doggie, there isn’t a new dog elegance launching to celebrate that, but Quarterly report and Fresh Zealand do use a cute tiny red leather bracelet gift emerge honour with it!

As a final point for innovative releases, this year’s limited edition Golf club charm is actually launching slightly earlier this coming year! The 2018 bead is often a globe layout, drawing for the theme of an global Pandora group. For an detailed examine this bead, you can check out my primary preview below. It has a pretty very little heart pandora bangle shaped field, as usual, this is usually marked while using year, to use in its collectability.

Assunto: Taxa de variação
Autor: felipe_ad - Ter Jun 29, 2010 19:44

Como resolvo uma questao desse tipo:

Uma usina de britagem produz pó de pedra, que ao ser depositado no solo, forma uma pilha cônica onde a altura é aproximadamente igual a 4/3 do raio da base.
(a) Determinar a razão de variação do volume em relação ao raio da base.
(b) Se o raio da base varia a uma taxa de 20 cm/s, qual a razão de variação do volume quando o raio mede 2 m?

A letra (a) consegui resolver e cheguei no resultado correto de \frac{4\pi{r}^{2}}{3}
Porem, nao consegui chegar a um resultado correto na letra (b). A resposta certa é 1,066\pi

Alguem me ajuda? Agradeço desde já.

V = (1/3)*pi*r²*h ----> h = 4r/3

V = (1/3)*pi*r²*(4r/3) ----> V = (4*pi/9)*r³


dV/dr = (4*pi/9)*(3r²) -----> dV/dr = 4pi*r²/3

Para dr = 20 cm/s = 0,2 m/s e R = 2 m ----> dV/0,2 = (4*pi*2²)/3 ----> dV = (3,2/3)*pi ----> dV ~= 1,066*pi m³/s

Temos que o volume é dado por:

V = \frac{4\pi}{3}r^2

Temos, portanto, o volume em função do raio. Podemos diferenciar implicitamente ambos os lados da equação em função do tempo, para encontrar as derivadas em função do tempo:

\frac{dV}{dt} = \frac{8\pi.r}{3}.\frac{dr}{dt}

Sabendo que a taxa de variação do raio é 0,2 m/s e que queremos ataxa de variação do volume quando o raio for 2 m:

\frac{dV}{dt} = \frac{8\pi.2}{3}.\frac{2}{10}

\frac{dV}{dt} = \frac{16\pi}{15}
