...**Math** **Problems** The standard equation of ellipse is: (x-h)2 a2 = (y-k)2 b2 Because the center of the Ellipse is at the origin, h and k equals to 0.
Because major axis lies on the x-axis, a equals to 1048ft/2 = 524 ft.
Because minor axis lies on the y-axis, b equals to 898ft/2 = 449 ft.
Therefore, the equation of the Ellipse looks like:
(x)2 / 5242 = (y)2 / 4492
2.
In order to find the principal and the rate, a system of two equations should be solved. One equation describes the return of the household before the change in principal and interest rate, the other - after the change, as shown below:
P * (1 + r) = P + 7.5
(P + 25) * (1+ r - 0.01) = P +25 +7.5,
where P is the initial investment and r is the initial rate (in decimal numbers...

Researchers in the field of second-language learning and mathematics word skills tend to agree that there is a basic difference between the success rates of students who are instructed initially in their native language and those who are expected to delve right into second-language instruction for all subjects. Generally speaking, students who are instructed in their primary language for a certain amount of time prior to engaging fully in a second language such as English have higher success rates on standardized tests and other individual measures of both language capability, and in particular, success with mathematical...

...**Math** **Problems** **Math** **Problems** Q The target capital structure for QM Industries is 36% common stock, 8% preferred stock, and 56% debt. If the cost of common equity for firm 17.4%, the cost of preferred stock is 10.1%, the before-tax cost of debt is 7.4%, and the firm’s tax rate is 35%, what is QM’s weighted average cost of capital (WACC)?
(Joshi, 2003)
Where:
Re = cost of equity = 17.4
Rd = cost of debt = 56
E = market value of the firms equity = 35
D = market value of the firms debt = 8
V = E + D = 43
E/V = percentage of financing that is equity = 10.1/43
D/V = percentage of financing that is debt = 7.4/43 (
WACC = (17.4/43)*10.1 + (7.4/43)*56*(1 – 1/8)
4.0870 + 9.6372*(1- 0.125) = 4.0870 + 7.05255 = 12. 520%

Consequently;
A would have gained $40000 had the contract not been repudiated. Yes, A would have gained $40000 under the contract, but A would have lost an income of $15000 that it no longer has to loose now. This means that it will take $25000 to bring A from where it now stands to where it would it would be if the contract hadn’t been repudiated.

Politicizing public service often becomes a major problem and this reprehensible practice was introduced during the regime of the Labour party government and was continued by the Coalition government. Due to this, the public servants have slowly commenced to divest themselves of accountability towards parliament or to the code of conduct (McLennan, 2004).<...
