Tyson does 80 sit-ups during his work out. He wants to increase his sit-ups by 25%. Which represents the new amount of sit-ups?

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 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.

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

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 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]

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.

What is dimensions?

The minimal set of coordinates required to specify any point within a mathematical space is known as the dimension of the space in physics and mathematics. As a result, a line has a dimension of one because a point on it can be specified by a single coordinate, such as the point at 5 on a number line.

Given:

Brianna has 34 m of fencing to build a three-sided fence around a rectangular plot of land that sits on a riverbank.

Since,

Area of rectangle = A = l x w        ..(1)

where l = length and w = width

Perimeter = 2w + l

34 = 2w + l

  l = 34 - 2w             ..(2)

Plug this value in equation (1).

A = (34 - 2w) x w

140 = 34w - 2w^2

2w^2 - 34w + 140 = 0

The dimension w can be found as follows;

w = - b / 2a

Here a = 2, b = -34

⇒ w = -(-34)/2(2) = 34/4 = 8.5

Hence, the width is 8.5 meters.

Now to find the length.

Plug w = 8.5 in equation (2)

l = 34 - 2(8.5)

Let the first point be P = P ( 0 , 5 )

Let the second point be Q = Q ( 4 , 3 )

Now , the slope of the line between the two points is given by

Slope m = ( y₂ - y₁ ) / ( x₂ - x₁ )

Now , the slope of the line between the two points is given by

Slope m = ( y₂ - y₁ ) / ( x₂ - x₁ )

Substituting the values in the equation , we get

Slope m = ( 1 - 3 ) / ( 8 - 4 )

Slope m = -2/4

Slope m = -1/2

So , the slope of the line m = -1/2

c)

The slope of the line m = -1/2 and it is constant

d)

The function is a linear function and the equation of line is given by

y - y₁ = m ( x - x₁ )
