Find volume of cone z=sqrt(x^2+y^2) that is bounded with z=5 and z=7

Nina [5.8K]

Convert to cylindrical coordinates first, using

$\begin{cases}x=r\cos\theta\\y=r\sin\theta\\z=\zeta\end{cases}$

Then the volume is

$\displaystyle\int_{\zeta=5}^{\zeta=7}\int_{\theta=0}^{\theta=2\pi}\int_{r=0}^{r=\zeta}r\,\mathrm dr\,\mathrm d\theta\,\mathrm d\zeta$
$=\displaystyle\pi\int_{\zeta=5}^{\zeta=7}\zeta^2\,\mathrm d\zeta$
$=\dfrac{218\pi}3$

AlladinOne [14]

Given:

initial amount deposited = $2,520
final amount acquired = $2,850
number of years = 2 years

Use the formula from economics,

F = P (1 + i)^n
2,850 = 2520 (1 + i)^ 2

solve for i

i = 6.3% per year <span />

Last year Jandik Corp. had $250,000 of assets (which is equal to its total invested capital), $18,750 of net income, and a debt-

Gemiola [76]

Answer:

change in capital to Improvement in ROE = 2.518%

Step-by-step explanation:

To calculate the improvement in ROE, calculate ROE for current capital structure by using DuPont analysis.

$ROE = Return\ on\ Assets \times Equity\ Multiplier$

where

Return on Assets = Net Income / Total Assets

$= \frac{18,750}{250,000} = 0.075$

Equity Multiplier = Total Assets / Equity

Equity = Total assets x (1 – debt to capital ratio)

= $250,000 x (1-37%)

= $157,500

Equity Multiplier = Total Assets / Equity

$= \frac{250,000}{157500} = 1.58$

ROE =0.075 x 1.58 = 0.11904761 or 11.905%

ROE after change in capital structure:

Equity = Total assets x (1 – debt to capital ratio)

= $250,000 x (1-48%) = $130,000

ROE = (18,750/250,000) x (250,000/130,000)

= 0.1442307692307692 or 14.423%

change in capital to Improvement in ROE = 14.423% - 11.905% = 2.518%
