Answer:

We have an algebra problem. Here we want to find the mid-value between 25.9 acres and 26 acres, we will find that the area of the compound is 25.95 acres.

For two given numbers A and B, such that A < B, the mid-value between these is given by:

A + (B - A)/2.

In this case, our two numbers are 25.9 and 26.

Using the above formula we get:

25.9 + (26 - 25.9)/2 =  25.95

Then we can conclude that the area of the compound is 25.95 acres.

Answer:

[tex]f'(x)=1+\ln x[/tex]

Step-by-step explanation:

[tex]f'(x)[/tex] is notation for the first derivative of [tex]f(x)[/tex].

Recall the product rule:

[tex](f\cdot g)'=f'\cdot g+g'\cdot f[/tex]

Therefore, we have:

[tex]\displaystyle \frac{d}{dx}(x\ln x)=\frac{d}{dx}(x)\cdot \ln(x)+\frac{d}{dx}(\ln x)\cdot x[/tex]

Note that:

[tex]\displaystyle \frac{d}{dx}(x)=1,\\\\\frac{d}{dx}(\ln x)=\frac{1}{x}[/tex]

Simplify:

[tex]\displaystyle \frac{d}{dx}(x\ln x)=1\cdot \ln x+\frac{1}{x}\cdot x, \\\\\frac{d}{dx}(x\ln x)= \ln x+1=\boxed{1+\ln x}[/tex]

The derivative is:

[tex] \bold{f(x) \: = \: x \: \times \: (In(x))}[/tex]

[tex] \bold{f'(x) \: = \: \frac{d}{dx} (x \: \times \: In(x))}[/tex]

[tex] \bold{f'(x) \: = \: \frac{d}{dx} (x) \: \times \: In(x) \: + \: x \: \times \: \frac{d}{dx} (In(x))}[/tex]

[tex] \bold{f'(x) \: = \: 1In(x) \: + \: x \: \times \frac{1}{x} }[/tex]

[tex] \bold{f'(x) \: = \: In(x) \: + \: x \: \times \: \frac{1}{x} }[/tex]

[tex] \boxed{ \bold{f'(x) \: = \: In(x) \: + \: 1}}[/tex]

Answer:

C

Step-by-step explanation:

There are two arcs a major and a minor arc. You should never have to rely on a diagram to get the right answer.

The circumference is 2 * pi * r

r = 6 km

C = 2* pi * 6

C = 12 pi

The arc size is

arc size = 135 / 360 * 12pi

arc size = 3/8 * 12 pi

arc size = 4 1/2 pi = 9 pi /2  km

Answer:

4x-2y =42 is the required equation

Step-by-step explanation:

given equation is,

4x-2y -7=0---------eqn1

parallel equation of given equation is

4x -2y+k =0-------eqn 2

now passing it through (9,-3), we get,

4×9 + 2×3 +k = 0

or,36+6+k =0

or,42+k =0

or, k= -42

putting the value of k in eqn2

4x-2y - 42=0

4x-2y = 42

Answer to your question:

Because the subtraction sign is after the negative, it applies to the term in front of it, in this case because there is a parenthesis, it would multiply into that and your equation from there would be 1-4-3x<-3. Then combine like terms from there.

Answer:

-3 - 16b

Step-by-step explanation:

by simply doing the multiplication and then add combinable terms.

9 - 4(3 + 4b) = 9 - 12 - 16b = -3 - 16b

Explanation:

Let's simplify step-by-step:

9-4(3 + 4b)

Distribute:

= 9 + (-4)(3) + (-4)(4b)

= 9 + (-12) + (-16b)

Combine Like Terms:

= 9 + (-12) + (-16b)

= (-16b) +(9 + (–12) )

= -16b + (-3)

Answer:

-16b + (-3)

Answer:

-35 and 7

Step-by-step explanation:

7 - 35 = -28

35 has a (-) sign, and 7 has a (+) sign

Addition can be defined as the process of adding two numbers. The two integers with different signs that have a sum of -28 are -29 and 1.

Addition can be defined as the process of adding two numbers such that the result is the combined value of the two numbers.

An integer is a number that can be written without using a fractional component.

Given that the two integers with different signs have a sum of -28. Therefore, we can write,

Hence, the two integers with different signs that have a sum of -28 are -29 and 1.

m = 12 miles

Cost paid by the violator = 80 + 10*12

Explanation:

We follow PEMDAS in reverse to undo every operation that is applied to variable x

Doing so will lead to the following

t = 0.4x + c

t - c = 0.4x

0.4x = t - c

x = (t - c)/(0.4)

The last equation is the same as writing [tex]x = \frac{t-c}{0.4}[/tex] which is what choice B shows.

Answer:

ab = 144

Step-by-step explanation:

Assuming you mean a² + b² = 612, then

(a + b)² = a² + 2ab + b² , that is

30² = a² + 2ab + b²  , so

a² + 2ab + b² = 900

a² + b² + 2ab = 900 ← substitute a² + b² = 612

612 + 2ab = 900 ( subtract 612 from both sides )

2ab = 288 ( divide both sides by 2 )

ab = 144

The aspect ratio represents the ratio of the width to the height of a television.  

The size of a TV is calculated using Pythagoras theorem. Assume the length ratio of the older 25-inch [tex]4:3[/tex] TV is x.

The ratio is represented as:

[tex]Width : Height = 4:3[/tex]

Using Pythagoras theorem, we have:

[tex]Width^2 + Height^2 = 25^2[/tex]

[tex](4x)^2 + (3x)^2 = 25^2[/tex]

[tex]16x^2 + 9x^2 = 625[/tex]

[tex]25x^2 = 625[/tex]

Divide both sides by 25

[tex]x^2 = 25[/tex]

Take positive square roots

[tex]x = 5[/tex]

So, the height of the image is:

[tex]Height = 3x[/tex]

[tex]Height = 3 \times 5 = 15[/tex]

While the width is

[tex]Width = 4x = 4 \times 5 = 20[/tex]

Hence, the height of the image is 15 inches

The height of each black bar is calculated as follows:

[tex]Width : Height = 2.35 : 1[/tex]

Where

[tex]Width = 20[/tex]

So, we have:

[tex]20 : Height = 2.35 : 1[/tex]

Express as fraction

[tex]\frac{Height}{20} = \frac{1}{2.35}[/tex]

Make Height the subject

[tex]Height = \frac{20}{2.35}[/tex]

[tex]Height = 8.51[/tex]

The height of each black bar at the top and at the bottom is 8.51 inches

The percentage of the screen’s area that is occupied by the image is calculated using

[tex]\% Screen = \frac{A_1}{A_2} \times 100\%[/tex]

Where

[tex]A_1 \to[/tex] Area of black bars

[tex]A_2 \to[/tex] Area of the 25-inch 4:3 television

So, we have:

[tex]A_1 =8.51 \times 20 = 170.2[/tex]

[tex]A_2 =15 \times 20 = 300[/tex]

[tex]\% Screen = \frac{A_1}{A_2} \times 100\%[/tex] becomes

[tex]\% Screen = \frac{170.2}{300} \times 100\%[/tex]

[tex]\% Screen = \frac{170.2}{3} \%[/tex]

[tex]\% Screen = 56.73 \%[/tex]

Hence, the percentage of the screen area occupied is 56.73%

Consumers moved to TV with a wide screen because a TV with wide screen shows bigger pictures than smaller dimension TV screens,

When the pictures are bigger, the consumers will have a clearer view of what they're watching.

Answer:

In 4 months, they will both have 132 stamps.

Step-by-step explanation:
