Mathematics

Step-by-step explanation:

f(x) =  ln( \frac{1}{x} )

To find the derivative, notice we have a function 1/x inside of another function, ln(x)

We use what we call the chain rule,

It states that

derivative of a '

\frac{d}{dx} f(g(x)) =  f '(g(x)) \times \: g '(x)

Here f is ln(x)

f is 1/x

So first, we know that

\frac{d}{dx} ( ln(x)  =  \frac{1}{x}

so

f'(g(x)) =  \frac{1}{ \frac{1}{x} }

We know that

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

So we have

x \times  -  \frac{1}{ {x}^{2} }  =   \frac{ - 1}{x}

Given: BC = 10 inches AC = inches m∠CBD = 60° m∠CAD = 90° Calculate the exact area of the shaded region. Show all work for full
Anna007 [38]

Answer:

23.3285 in²

Step-by-step explanation:

From the above diagram, we can see that the shaded portion is a circular in shape. The shaded portion is coming together of two segments of two circles

The formula for the area of the segment is given as:

A = (½) × r² × [(π/180) θ – sin θ]

 Where,

 r: radius of the circle

θ = angle

a) Circle 1: the largest circle:

A = (½) × r² × [(π/180) θ – sin θ]

 r: radius of the circle = 10 inches

θ = angle = 60°

A = (½) × 10² × [(π/180) × 60° – sin 60]

A = 9.0586 in²

b) Circle 2: the smallest circle:

A = (½) × r² × [(π/180) θ – sin θ]

 r: radius of the circle = √50 inches

θ = angle = 90°

A = (½) × (√50) ² × [(π/180) × 90° – sin 90]

A = 14.2699 in²

 Total area of the shaded portion:

Area of the segment of the large circle + Area of the segment of the small circle

A = 9.0586 in² + 14.2699 in²

A = 23.3285 in²

Calculate the volume of the figure.
Margarita [4]

Answer:

Step-by-step explanation:

Formula

Volume = L * w * h

Givens

L = 7 feet

w = 4 feet

h = 5 feet

Solution

V = L * w * h             Substitute values into the formula

V = 7 * 4 * 5

V = 140 cubic feet.

Answer

140 ft^3

8 customers entered a store over the course of 16 minutes. At what rate were the customers entering the store in minutes per cus
lilavasa [31]

Answer:

<h3>2min/customer</h3>

Step-by-step explanation:

If 8 customers entered a store over the course of 16 minutes, then;

8 customers = 16 minutes.

The rate at which the customers are entering is expressed as;

Rate = Time (in minutes)/amount of customers;

Given

Time = 16 minutes

Amount of customers = 8 customers

Rate = 16min/8customers

Rate = 2min/customer

Hence the rate at which the customers entering the store in minutes per customer is 2min/customer.
