Please help with this AP Calculus question !

melomori [17]

Answer:

C. $\displaystyle \frac{cos(x)}{x} - ln(x)sin(x)$

General Formulas and Concepts:

<u>Calculus</u>

Differentiation

Derivatives
Derivative Notation

Derivative Rule [Product Rule]: $\displaystyle \frac{d}{dx} [f(x)g(x)]=f'(x)g(x) + g'(x)f(x)$

Trig Derivatives

Logarithmic Derivatives

Step-by-step explanation:

<u>Step 1: Define</u>

<em>Identify</em>

$\displaystyle f(x) = ln(x)cos(x)$

<u>Step 2: Differentiate</u>

Derivative Rule [Product Rule]: $\displaystyle f'(x) = \frac{d}{dx}[ln(x)]cos(x) + ln(x)\frac{d}{dx}[cos(x)]$
Logarithmic Derivative: $\displaystyle f'(x) = \frac{1}{x}cos(x) + ln(x)\frac{d}{dx}[cos(x)]$
Trig Derivative: $\displaystyle f'(x) = \frac{1}{x}cos(x) + ln(x)[-sin(x)]$
Simplify: $\displaystyle f'(x) = \frac{cos(x)}{x} - ln(x)sin(x)$

madreJ [45]

Answer:

Option A

Step-by-step explanation:

A translation 5 units down, followed by a 180-degree counterclockwise rotation about the origin

Correct

A translation 5 units down, followed by a 270-degree counterclockwise rotation about the origin

Incorrect. It would work with 180-degree rotation.

A 180-degree counterclockwise rotation about the origin, followed by a translation 5 units down

Incorrect. It would work with the translation 5 units up.

A 270-degree counterclockwise rotation about the origin, followed by a translation 5 units down

Incorrect.

-2 times g(4) when g(x) =-x squared+(4x)-11

andrezito [222]

Answer:

+22

Step-by-step explanation:

Given g(x) = -x^2 + 4x - 11, g(4) is -(4)^2 + 4(4) - 11, or just -11.

Then -2 times g(4) = -2(-11) = +22

Order the measurements from the least to the greatest. 2,720 mL , 24.91 L , 0.0268 kL

iren [92.7K]

2720ml=2.720L
0.0268kl=26.8L
24.91l
Therefore
2720ml , 24.91L, 0.0268kl
Is the correct order
