writing 5a2b − 13ab 7a3 − 4b in polynomial decending order

f(-7) will be equal to (-13) using given function and conditions.

What are function?

Function is an expression rule, or law that defines relationship between one variable and another variable.

An example of this would be y = x^2. If you put in anything for x, you get one output for y.

In given function,

y is represented by f(x),

f(x) = -x-6  for x ≠ 0

f(x) = 2      for x = 0

We need to find for x = -7 i.e. not equal to 0

So, we will take F(x) = -x-6

So, f(-7) = -7-6

             = -13

So, the value of f(-7) = -13.

The number of apples obtained from the product of the fraction represented by the apples and the total number of fruits is 5 apples.

A fraction is a representation of the proportion or part of a whole quantity.

The fraction of the fruit that are apples = One quarter = 1/4

The fraction of the fruit that are oranges = One quarter of the number of fruits

The number of bananas = 4

Number of pear = 3

Number of plums = 3

The fraction of the whole fruit are represented by  apples and oranges = (1/4) + (1/4) = 1/2

The fraction of the total number of fruits represented by the bananas, pear and plum = 1 - (1/4 + 1/4)) = 1/2

Therefore;

Half of the total number of fruits = 4 + 3 + 3 = 10 fruits

Half of the fruits = 10

The total number of fruits is therefore, n = 2 × 10 = 20

The number of fruits that are apples = (1/4) × The total number of fruits

Therefore, the number of apples = (1/4) × 20 = 5

The value of natural logarithm, ln(1/0.32) where base "e" or e =2.7182 is 1.13943..

Logarithm, an exponent or power that must be raised to obtain a particular number. Expressed mathematically, x is the logarithm of n in base a, where x = logₐ n.

Basic Rules:

Wehave given that,

ln(1/0.32) here , a = 1 , b = 0.32

using formula, ln(1/0.32) = ln(1) - ln(0.32)

Now, from logarithm table , log(1) = 0

log(0.32)= ln(0.32) = - 1.13943

ln(1/0.32) = ln(1) - ln(0.32) = 0-(- 1.13943)

=> ln(1/0.32) = 1.13943

The value of (1 + i)^5 is -2 * 2^1.5 * (1 + i). De Moivre's describes how the power of a complex number can be calculated using the properties of its modulus and argument.

De Moivre's theorem states that for any complex number z and any integer n, we have (z^n) = (r^n)(cos(nθ) + i * sin(nθ)), where r is the magnitude of z and θ is the angle that z makes with the positive real axis in the complex plane. Using this theorem, we can easily find the fifth power of 1+i as follows:

First, we need to express 1+i in polar form, which is given by z = r * cis(θ), where r is the magnitude of z and cis(θ) is the complex number with magnitude 1 and angle θ in the complex plane. In this case, we have z = 1+i = sqrt(2) * cis(π/4), where sqrt(2) is the magnitude of 1+i and cis(π/4) is the complex number with magnitude 1 and angle π/4 in the complex plane.

Next, we substitute this expression for z into the formula for (z^n) given by De Moivre's theorem, which gives us

(1 + i)^5 = √2^5 * (cos(5 * 45) + i * sin(5 * 45))

        = 2^2.5 * (cos(225) + i * sin(225))

(1 + i)^5 = 2^2.5 * (-cos(45) + i * -sin(45))

        = 2^2.5 * (-1 + i * -1)

        = -2 * 2^1.5 * (1 + i)

Therefore, the value of (1 + i)^5 is -2 * 2^1.5 * (1 + i).

Length of the curve is e² - 1 .

What is function?

In arithmetic, a function from a group X to a group Y assigns to every part of X precisely one part of Y. The set X is termed the domain of the function and therefore the set Y is termed the codomain of the function

Main body:

A parametric curve is a function expressed in components form, such that

x=f(t) , y=g(t). The length of a parametric curve on the interval a ≤ t ≤ b is given by the definite integral :

L =  [tex]\int\limits^a_b {\sqrt{(\frac{dx}{dt} )^2 + (\frac{dy}{dt} )^2} } \, dt[/tex]

Let's begin by getting the first derivative of the components of the function with respect to the variable t.

x = e^t - t  

dx / dt = e^t−1

y = 4 e^t/2

dy /dt = 2 e^t/2

Substitute the derivatives into the following definite integral which computes the length of the parametric curve on the interval

[a,b]=[0,2].

L =[tex]\int\limits^a_b {\sqrt{(\frac{dx}{dt} )^2 + (\frac{dy}{dt} )^2} } \, dt[/tex]

L=  [tex]\int\limits^2_0 {\sqrt{(e^{t}-1 )^2 + (2e^{t/2} } )^2} } \, dt[/tex]

L =[tex]\int\limits^2_0 {e^{t} -1} \, dt[/tex]

Evaluate the solution at the limits of integration to get the length.

L = (e² - 1 )- (e⁰ - 1)

L = e² - 1 - 1 + 1

L= e² - 1

Ezra's tree starts at 8 inches and grows 5 inches every year, so we can represent that as 5x+8

x=years

So, now that we have an equation for each tree, we will now set them as equal

5x+8=3x+14

Subtract 8 from each side

5x=3x+6

Subtract 3x from each side

2x=6

Divide each side by 2

x=3

It will take 3 years for the trees to reach the same height.

The solution of the equation after completing the square of the equation is found as; x = ±√19 + 2.

A scatterplot represents a group of points displayed on both the horizontal and vertical axes. Scatter plots are very important in the field of statistics because they can show the degree of correlation that exists between the values ​​of observed quantities or events (called variables). Scatter plots are used to show the degree to which one variable is influenced by another by plotting data points on horizontal and vertical axes. This is done to show how closely related the two variables are.

The equation of the perpendicular line to the given line is, [tex]y = \frac{4}{5}x - 8[/tex].

What is perpendicular lines?

When two geometric objects intersect at a right angle, they are considered to be perpendicular in elementary geometry. By using the perpendicular symbol,, the condition of perpendicularity can be graphically represented. Between two lines, a line and a plane, or between two planes can be used to define it.

Consider the given equation of line

5x + 4y = 10

Convert it into the form y = mx + c

⇒ 4y = -5x + 10

y = -5/4x + 10/4

y = -5/4x + 5/2

Here the slope of line is, -5/4.

The slope of perpendicular line is negative reciprocal of the slope of given line.

So, the slope of perpendicular line is,

[tex]-\frac{1}{(-5/4)} = \frac{4}{5}[/tex]

Also the line passes through the point (5, -4).

By using the point slope form to find the equation of line

[tex]y-y_1 = m(x-x_1)\\y-(-4) = \frac{4}{5}(x-5)\\ y+4=\frac{4}{5}x - 4\\ y = \frac{4}{5}x - 4 - 4\\ y = \frac{4}{5}x - 8[/tex]

Hence, the equation of the perpendicular line to the given line is, [tex]y = \frac{4}{5}x - 8[/tex].

(A) cylindrical coordinate = (r, θ, z) = (√2, -π/4, 1)

(B) cylindrical coordinate = (r, θ, z) = (14, -π/3, 7)

In the given question, we have to change from rectangular to cylindrical coordinates. (let r ≥ 0 and 0 ≤ θ ≤ 2π.)

A) (-1,1,1)

Given rectangular coordinates(x, y, z) = (-1,1,1)

The cylindrical coordinates are (r, θ, z)

So we find the value of r and θ one by one.

r = √x^2+y^2

r = √(-1)^2+(1)^2

r = √1+1

r = √2

θ = [tex]\tan^{-1}[/tex](y/x)

θ = [tex]\tan^{-1}[/tex](1/-1)

θ = [tex]\tan^{-1}[/tex](-1)

θ = -π/4

So cylindrical coordinate = (r, θ, z) = (√2, -π/4, 1)

B) (-7,7√3,7)

Given rectangular coordinates(x, y, z) = (-1,1,1)

The cylindrical coordinates are (r, θ, z)

So we find the value of r and θ one by one.

r = √x^2+y^2

r = √(-7)^2+(7√3)^2

r = √49+147

r = √196

r = 14

θ = [tex]\tan^{-1}[/tex](y/x)

θ = [tex]\tan^{-1}[/tex](7√3/-7)

θ = [tex]\tan^{-1}[/tex](-√3)

θ = -π/3

Generally speaking, a S corporation is put up to reduce the tax obligations. It is Option (3).

A business form known as a S corporation is one that is allowed by the tax code to distribute its taxable income, credits, deductions, and losses to its shareholders directly. This provides it certain advantages over the more popular C corp. The S corp, an alternative to the limited liability company, is only available to small firms with 100 or fewer stockholders (LLC). S corporations and LLCs are both referred to as "pass-through entities" since they don't pay corporate taxes, instead, they pay their owners, who are then in charge of paying the necessary taxes.

One sort of legal corporate structure that is popular among small businesses is the S corporation, commonly referred to as a S corp or S corp or S subchapter. Another is a limited liability company (LLC). A corporation with 100 shareholders or fewer can profit from incorporation while still being taxed as a partnership thanks to the requirements of a S corp.
