Answer:

D) $\frac{4x-3} {x+6}$

Step-by-step explanation:

First we have to factorize and then cancel the like terms.

Given,

$\frac{4x^2-7x+3} {x^{2}+5x-6}\\=\frac{4x^2-3x-4x+3} {x^{2}+6x-x-6}\\=\frac{x(4x-3)-1(4x-3)} {x(x+6)-1(x+6)}\\=\frac{(4x-3)(x-1)} {(x+6)(x-1)}$

Now, we got the like term (x-1).

Canceling this like term we get

$\frac{(4x-3)(x-1)} {(x+6)(x-1)}=\frac{4x-3} {x+6}$

Answer:

$4884.75

Step-by-step explanation:

The amount in a simple interest account is given by the formula ...

A = P(1 +rt)

Here, we have principal P=$4500, interest rate r=0.0285, and time t=3. Then the amount in the savings account will be ...

A = $4500(1 +.0285·3) = $4500·1.0855 = $4884.75

Integrate sin²2x cos²2xdx

Masteriza [31]

$\sin^2x=\dfrac{1-\cos2x}2$
$\cos^2x=\dfrac{1+\cos2x}2$

From the identities above, you have

$\sin^22x\cos^22x=\dfrac{(1-\cos4x)(1+\cos4x)}4=\dfrac{1-\cos^24x}4$

Applying once more, you have

$\dfrac{1-\cos^24x}4=\dfrac{1-\dfrac{1+\cos8x}2}4=\dfrac{1-\cos8x}8$

So,

$\displaystyle\int\sin^22x\cos^22x\,\mathrm dx=\frac18\int(1-\cos8x)\,\mathrm dx=\frac x8-\frac1{64}\sin8x+C$
