Differentiating a Logarithmic Function in Exercise, find the derivative of the function. See Examples 1, 2, 3, and 4.

kotykmax [81]

Answer:

$f'(x) = -\frac{2x}{1 - x^{2}}$

Step-by-step explanation:

The derivative of an addition/subtraction of terms is the addition/subtraction of the derivatives of these terms.

The derivative of a constant is 0.

The derivative of $a*x^{n}$ is $a*n*x^{n-1}$ . The derivative of $x^{3}$ is $3x^{2}$ , for example.

The derivative of the ln function:

If we have:

$y = \ln{g(x)}$

The derivative is

$y' = g'(x)*\frac{1}{g(x)}$

In this problem, we have that:

$y = \ln{1 - x^{2}}$

So $g(x) = 1 - x^{2}$ and $g'(x) = -2x$

So the derivative to this function is

$f'(x) = -\frac{2x}{1 - x^{2}}$

It would be 10 because the factors add up and it makes sense

17. The length of a rectangle is 12 in, and the perimeter is 56 in. Find the width of the rectangle.

Ivahew [28]

Answer:

Step-by-step explanation:

P = 2(L + W)

P = 56

L = 12

now sub...we are looking for w

56 = 2(12 + W)

56 = 24 + 2W

56 - 24 = 2W

32 = 2W

32/2 = W

16 = W <==== the width is 16 inches

check...

P = 2(L + W)

56 = 2(12 + 16)

56 = 2(28)

56 = 56 (correct)

X+2y=6<br> 2x+4y=12<br><br> I need to use substitution to solve, may anybody help?

lana66690 [7]

$x + 2y = 6$

$x = - 2y + 6$
$2( - 2y + 6) + 4y = 12$
then find y and plug that y value into one of the original equations to find x

Hope this helps!
