Answer:

The answer to the expression 3(6x-4y)-5 is 18x - 12y - 5. This is the result of following the order of operations and performing the necessary operations in the correct sequence.

Step-by-step explanation:

To solve this problem, you need to follow the order of operations, which is a set of rules that dictate the sequence in which operations should be performed in a mathematical expression to get the correct result. The order of operations is often abbreviated using the acronym PEMDAS, which stands for Parentheses, Exponents, Multiplication and Division (from left to right), and Addition and Subtraction (from left to right).

According to the order of operations, the first step in solving this problem is to evaluate anything inside parentheses. In this case, there are no parentheses, so we can move on to the next step, which is to evaluate any exponents. Again, there are no exponents in this expression, so we can move on to the next step, which is to perform any multiplication or division.

In this case, there is a multiplication operation: 3 * (6x - 4y). So we need to evaluate this first. To do that, we need to multiply 3 by each of the terms inside the parentheses: 3 * 6x and 3 * -4y. This gives us 18x - 12y.

Now that we have performed all of the multiplication and division operations, we can move on to the final step, which is to perform any remaining addition or subtraction operations. In this case, there is only one subtraction operation: 18x - 12y - 5. So we need to subtract 5 from 18x - 12y to get our final answer: 18x - 12y - 5 = 18x - 12y - 5.

Therefore, the result of evaluating the expression 3(6x-4y)-5 is 18x - 12y - 5. I hope this helps! Let me know if you have any other questions.

The integral of f (z) around the positively oriented circle |z|

[tex]\int\limits^_ {} \,[/tex]f(z) dz = -8πi/3

In mathematics, an integral lends numerical values to functions to represent notions like volume, area, and displacement that result from combining infinitesimally small amounts of data. Integration is the action of locating integrals.

With the exception of the point where z = z, where f(z) is analytic within and on C, let C be the smooth, simple closed curve except at z =z , then ,

[tex]\int\limits^_ {} \,[/tex] f(z) dz = 2πi [ res f(z)] z = [tex]z_{1}[/tex]

here f(z) is singular at z = -1,

res  [tex]f(z)_{z = -1}[/tex] = [tex]\lim_{z\to \-1} z+1 f(z)_[/tex]

[tex]\lim_{z\to \-1}[/tex] [tex]z^{3}[/tex](1-3z)/(1+2[tex]z^{4}[/tex])

when z = -1 then f(z) = -4/3

Therefore [tex]\int\limits^_ {} \,[/tex]f(z) dz = 2πi (-4/3)

[tex]\int\limits^_ {} \,[/tex]f(z) dz = -8πi/3.

Answer:

The missing term in the output of the function [tex]g(f(x))[/tex] is -18.

[tex]g(f(x))=10x^2-18[/tex]

Step-by-step explanation:

In mathematics, function composition is a term that encompasses a relationship between two functions wherein the output of one function is used as the input for another function. This relationship combines two functions to form a single function, known as a composite function. For future reference, function composition may also be denoted by a small circle, see below:

[tex](g\circ f)(x)=g(f(x))[/tex]

In the given problem, we must evaluate the composite function [tex]g(f(x))[/tex] / [tex](g\circ f)(x)[/tex] to identify the unknown term.

With composite functions, we begin evaluating from the inside. To evaluate [tex]g(f(x))[/tex], we must substitute the output of the function [tex]f(x)[/tex] (given as the expression [tex]2x^2-5[/tex]) as the input ([tex]x[/tex]) for the function [tex]g(x)[/tex]:

[tex]g(f(x))=g(2x^2-5)[/tex]

Now, using [tex]f(x)[/tex] as the input ([tex]x[/tex]) for the function [tex]g(x)[/tex] (given as the expression [tex]5x+7[/tex]), we can substitute [tex]2x^2-5[/tex] into the output for the function [tex]g(x)[/tex]:

[tex]g(f(x))= 5(2x^2-5)+7[/tex]

From here, we can go ahead and distribute the 5:

[tex]g(f(x))=10x^2-25+7[/tex]

Combine like terms:

[tex]g(f(x))=10x^2-18[/tex]

With the composite function evaluated, we can identify our missing term as [tex]-18[/tex].

The polynomial y = (4 / 3) · x³ + (16 / 3) · x² + (4 / 3) · x - 8 is the cubic equation whose zeros are x₁ = -3, x₂ = - 2, x₃ = 1 and intercept is - 8.

Herein we must derive a cubic equation such that the zeros are x₁ = -3, x₂ = - 2, x₃ = 1 and its intercept is - 8. Cubic equations are polynomials of the form y = a · x³ + b · x² + c · x + d, where a, b, c, d are real coefficients.

If we know that (x₁, y₁) = (- 3, 0), (x₂, y₂) = (- 2, 0), (x₃, y₃) = (1, 0) and (x₄, y₄) = (0, - 8), then we solve the following system of linear equations to determine all real coeffcients by numerical methods:

- 27 · a + 9 · b - 3 · c + d = 0

- 8 · a + 4 · b - 2 · c + d = 0

a + b + c + d = 0

d = - 8

(a, b, c, d) = (4 / 3, 16 / 3, 4 / 3, - 8)

The cubic equation is y = (4 / 3) · x³ + (16 / 3) · x² + (4 / 3) · x - 8.

Answer: The equation for simple interest is:

Future interest = Principal*(interest rate*number of years). Remember to write the interest rate of 1.25% as 0.0125 (rather than directly as 1.25)

812.50 = x(0.0125*20)

812.5 = x(0.25)

x = $3250

This means that Samson deposited $3250 when he opened the account.

Step-by-step explanation:

The triangle has three side x,y and √(x²+y²), the slope of x is zero, the slope of y is undefined, the slope of √(x²+y²) is tanα. The coordinate of the midpoint of x is x/2,0 and y is 0, y/2

suppose the triangle is right-angled and the sum of other two angles are also 90 degrees. we know that the side opposite to the right angle is called hypotenuse. let the other two side is denoted by x and y. Now, x is the base of triangle, and the rest of the side is y. The angle between hypotenuse and base is denoted by α . As per Pythagorean theorem, hypotenuse = √(x²+y²).

slope can be calculated by tanα or using the formula (y₂-y₁)/(x₂-x₁)

according to trigonometric ratio, tanα = opposite side/base = x/y

 tanα is the slope of hypotenuse.

the side length x is along the horizontal axis, so its y coordinate is zero and slope is also zero.

the side length y is along the vertical axis whose x coordinate is zero that means slope is undefined.

As per the formula (y₂-y₁)/(x₂-x₁) used to calculate slope, whenever x coordinate is zero the result is written as undefined.

hence, the triangle is right-angled, and the biggest side has a slope only.

the number under a square root is always 0 or a positive number, so it can’t be equal to a negative number

The solution is

A) The domain to plot the growth function is Domain = [ 0 , 8 ]

B) The y-intercept of the graph of the function f ( a ) is f ( 0 ) = 3 cm

C) The average rate of change of the function f ( a ) from m = 2 to m = 8 is given by T = 0.4022 cm per month

The equation of a line is expressed as y = mx + b where m is the slope and b is the y-intercept

And y - y₁ = m ( x - x₁ )

y = y-coordinate of second point

y₁ = y-coordinate of point one

m = slope

x = x-coordinate of second point

x₁ = x-coordinate of point one

The slope m = ( y₂ - y₁ ) / ( x₂ - x₁ )

Given data ,

Let the equation be represented as A

Now , the value of A is given by

f ( a ) = 3 ( 1.09 )ᵃ

A)

To find the domain of the function f ( a )

The length of the fish was approximately 5.98 cm

So , substituting the value of f ( a ) as 5.98 cm , we get the value of m,

And , f ( a ) = 5.98 cm

So , 5.98 = 3 ( 1.09 )ᵃ

Solving for a , we get

Divide by 3 on both sides of the equation , we get

1.9933 = ( 1.09 )ᵃ

a = 8

So , the value of a is 8

So , the domain of the function is [ 0 , 8 ]

B)

The y-intercept of the graph is given by substituting the value of a = 0,

So , f ( a ) = 3 ( 1.09 )ᵃ

when a = 0 , we get

f ( 0 ) = 3 ( 1.09 )⁰

f ( 0 ) = 3 cm

Therefore,  the value of f ( 0 ) = 3 cm

C)

The average rate of change from m =2 to m = 8 is given by the equation ,

when m = 2 ,

f ( a ) = 3 ( 1.09 )ᵃ

f ( 2 ) = 3 ( 1.09 )²

f ( 2 ) = 3 x 1.1881²

f ( 2 ) = 3.5643

And , when a = 8

f ( a ) = 3 ( 1.09 )ᵃ

f ( 8 ) = 3 ( 1.09 )⁸

f ( 8 ) = 3 x 1.99256

f ( 8 ) = 5.97768

So , the average rate of change is the slope of the graph

Slope = ( y₂ - y₁ ) / ( x₂ - x₁ )

Substituting the values in the equation , we get

Slope = f ( 8 ) - f ( 2 ) / ( 8 - 2 )

Slope = ( 5.97768 - 3.5643 ) / 6

Slope = 2.4133879 / 6

Slope = 0.40223 cm per month

Therefore ,

The average rate of change of the function f ( a ) from a = 2 to a = 8 is given by T = 0.4022 cm per month

Hence ,

A) The domain to plot the growth function is Domain = [ 0 , 8 ]

B) The y-intercept of the graph of the function f ( m ) is f ( 0 ) = 3 cm
