If f(x)=ln(sin(2x)), f''(π/4) is equal to

Licemer1 [7]

Use the chain rule to compute the second derivative:

$f(x)=\ln(\sin(2x))$

The first derivative is

$f'(x)=(\ln(\sin(2x)))'=\dfrac{(\sin(2x))'}{\sin(2x)}=\dfrac{\cos(2x)(2x)'}{\sin(2x)}=\dfrac{2\cos(2x)}{\sin(2x)}$

$f'(x)=2\cot(2x)$

Then the second derivative is

$f''(x)=(2\cot(2x))'=-2\csc^2(2x)(2x)'$

$f''(x)=-4\csc^2(2x)$

Then plug in π/4 for <em>x</em> :

$f''\left(\dfrac\pi4\right)=-4\csc^2\left(\dfrac{2\pi}4\right)=-4$

What is the slope-intercept equation of the line below? y - i ntercept = (0, - 4) slope = 3

Artist 52 [7]

Answer:

y = 3x -4

Step-by-step explanation:

The slope-intercept equation looks like this: $y = mx +b$ . Where m is the slope of the function and b is the y-coordinate of the vertical intercept (where the function crosses the y-axis). Let's apply the formula:

$y = mx +b$

$y = 3x +(-4)$

$y = 3x -4$

Samuel bought a jacket for $16 in January. The cost of the jacket increased to $24 in September. What percent of the original pr

Assoli18 [71]

Answer:

The answer is option C=150%

Step-by-step explanation:

Original cost of the jacket=$16 in January

Final cost of jacket=$24 in September

What percentage must of the original price is the new?

The new price=the original price×(A percentage)

Where the new price=$24, the original price=$16, and the percentage=(x/100)

24=16×x/100

x=(24×100)/16=150%

The answer is 150%
