The following integral requires a preliminary step such as long division or a change of variables before using the method of par

shtirl [24]

Division yields

$\dfrac{x^4+7}{x^3+2x} = x-\dfrac{2x^2-7}{x^3+2x}$

Now for partial fractions: you're looking for constants a, b, and c such that

$\dfrac{2x^2-7}{x(x^2+2)} = \dfrac ax + \dfrac{bx+c}{x^2+2}$

$\implies 2x^2 - 7 = a(x^2+2) + (bx+c)x = (a+b)x^2+cx + 2a$

which gives a + b = 2, c = 0, and 2a = -7, so that a = -7/2 and b = 11/2. Then

$\dfrac{2x^2-7}{x(x^2+2)} = -\dfrac7{2x} + \dfrac{11x}{2(x^2+2)}$

Now, in the integral we get

$\displaystyle\int\frac{x^4+7}{x^3+2x}\,\mathrm dx = \int\left(x+\frac7{2x} - \frac{11x}{2(x^2+2)}\right)\,\mathrm dx$

The first two terms are trivial to integrate. For the third, substitute y = x ² + 2 and dy = 2x dx to get

$\displaystyle \int x\,\mathrm dx + \frac72\int\frac{\mathrm dx}x - \frac{11}4 \int\frac{\mathrm dy}y \\\\ =\displaystyle \frac{x^2}2+\frac72\ln|x|-\frac{11}4\ln|y| + C \\\\ =\displaystyle \boxed{\frac{x^2}2 + \frac72\ln|x| - \frac{11}4 \ln(x^2+2) + C}$

A store offers a 15% discount on all items in the store during a sale. All store employees get an additional 10% employee discou

Ivan

The equation that returns the cost, C, that in employee has to pay is:

C = 0.765x + 0.06(0.765x)

Where x is the price before discount, 0765 is the price after discount and before taxes, and 0.06(0.765x) is the value of the tax.

Furthermore, note where 0765 comes from:

x less 15% disscount = x - 0.15x = 0.85x;

0.85 less 10% disscount = 0.85x - 0.1*0.85x = 0.85x - 0.085x = 0.765x.

So, you just must replace the price in the formula:

C = 0.765($100) + 0.06(0.765*$100) = $76.5 + $4.59 = $81.09

Answer: 81.09
