Answer: y^3 - 6y^2 + 5y

Step-by-step explanation: You start by rewriting the expression y^3- 5y^2/y +(y-1)

Then you factor out y(y^2-5y)/y *(y-1)

Then you reduce the fraction which cancels the 2 y’s out (y^2-5y)(y-1)

Then you multiple the 2 parentheses which equals y^3-y^2-5y^2+5y

Then you simply the answer you got which comes out to y^3-6y^2+5y

Answer:

The answer is -26

Answer:

1. (2x + 4)(x - 3) = 0

2. The solutions to the expression are

-2 and 3.

Step-by-step explanation:

1. The expression 2x² - 2x - 12 = 0

can be expressed in factor form as follow:

2x² - 2x - 12 = 0

Multiply the first term i.e 2x² and the last term i.e -12 together. We have:

2x² × -12 = -24x²

Next, look for two factors of -24x² such that their sum will result to the 2nd term i.e -2x in the expression above. The two factors are -6x and 4x.

Next, substitute -6x and 4x in place of -2x in the expression above i.e

2x² - 2x - 12 = 0

2x² - 6x + 4x - 12 = 0

Next, we shall factorize

2x(x - 3) + 4(x - 3) = 0

(2x + 4)(x - 3) = 0

2. The solution to expression

(2x + 4)(x - 3) = 0

2x + 4 = 0 or x - 3 = 0

Collect like terms

2x = 0 - 4 or x = 0 + 3

2x = - 4 or x = 3

x = - 4/2 or x = 3

x = - 2 or 3

Therefore, the solutions to the expression are - 2 and 3.

Step-by-step explanation:

a. Jump with a bobbing motion: Shortest jump  b. Jump from deep knee flexion: Intermediate jump

c. Jump with fully extended knees: Longest jump ,In the long jump activity, three different jumping techniques were observed:

a) The bobbing motion involved bending and extending the knees and arms during the jump.

b) Starting from deep knee flexion meant initiating the jump from a position with knees bent and no motion prior to the jump.

c) Starting with fully extended knees involved jumping with the knees straight and no motion before the jump. During the performance, the lengths of each jump were measured. Trial results consistently indicated that the jump with the bobbing motion had the shortest length, while the jump starting from deep knee flexion had an intermediate length. The jump with fully extended knees consistently achieved the longest distance.

The observations reveal that starting the jump with fully extended knees and no knee motion results in the longest jump. The bobbing motion with knee and arm movements leads to the shortest jump. Deep knee flexion position falls between the two in terms of jump length.

13. \(12.88m\)

14. \(10ft\)

Step-by-step explanation:

To calculate the circumference, use the following formula, where \(d\) is the diameter:

\(C = \pi d\\C = 3.14159 * 4.1 = 12.88m\)

To find the arc length, use the following formula, where \(r\) is radius and \(\theta\) is the angle in radians:

\(s = r\theta\)

Before you plug in any values, convert the angle from degrees to radians using the following formula, where x is the angle in degrees:

\(\theta = \frac{x}{180}\pi\\\theta = \frac{144}{180}\pi\\\theta \approx 2.5\)

Now plug in your values:

\(s = 4 \cdot 2.5\\s = 10ft\)

The congruent postulate in which two corresponding angles and non-Included side of the two triangles are congruent is AAS. AAS is an abbreviation of angle angle side postulate.

Triangles are said to be congruent if they are of  identical sides and angles. The three sides of first triangle are exactly equal in measure to the three sides of second triangle. The three angles of first are each the same angle as the second triangle.

Triangles are said to be congruent when all corresponding sides and interior angles are congruent. The triangles will have same shape and size, but the first triangle may be a mirror image of the other triangle.  

The definition of Angle Angle Side Theorem also states that-

If two angles and the non-included side of first triangle are congruent to the corresponding parts of second triangle, then the  triangles are said to be congruent.

Other theorems which triangles follow are Side Angle Side, Side Side Angle, Angle Side Side, Side Side Side, Angle Angle Angle etc.

Answer:

Total earned with $225 sales = $233.75

Total earned with x sales = 0.15x+200

Step-by-step explanation:

Given that:

Base salary of Leah per week = $200

Commission paid = 15%

Sales made by Leah = $225

Commission = 15% of 225

Commission = \(\frac{15}{100} * 225\)

Commission = 0.15 * 225

Commission = $33.75

Total earned = 200 + 33.75 = $233.75

Commission when sales are x

Commission = 0.15x

Total earned = 0.15x+200

In response to the given query, we can state that Therefore, for the initial equation payment, the principle received was $224.93, the interest was $18.67, and the new principal was $2,575.07.

A mathematical equation is a process that links two statements and indicates equivalence with the equals sign (=). In mathematics, an equation is a mathematical statement that proves the equality of two mathematical expressions. For example, the equal sign separates the numbers 3x plus 5 and 14 in the equation 3x + 5 = 14. A mathematical formula can be used to understand the connection between the two lines that are written on opposite sides of a letter. In many cases, the logo and the particular program are identical. as in 2x – 4 = 2, for instance.

P = (r * A) / (1 - (1 + r)^(-n))

A = $2,800.00

r = 8% / 12 = 0.00666666667

n = 12

These numbers allow us to determine the weekly payment:

P = (0.00666666667 * $2,800.00) / (1 - (1 + 0.00666666667)^(-12)) = $243.60

the amount due each month is $243.60.

Utilizing the following method, we can determine the first payment's breakdown:

Interest is calculated as follows: New Principal is equal to Current Principal minus Monthly Payment - Interest Interest = Current Principal * Monthly Interest Rate

As for the initial payment:

Monthly Interest Rate = 8% / 12 = 0.00666666667 Current Principal: $2,800.00

Interest equals $2,800.00 times 0.00666666667, or $18.67.

Payment to Principal: $243.60 less $18.67 equals $224.93.

$2,800.00 - $224.93 = $2,575.07 is the new principal.

Therefore, for the initial payment, the principle received was $224.93, the interest was $18.67, and the new principal was $2,575.07.

About 3.25 seconds have gone by when the rocket is at its highest point.

The height of the rocket at any time t can be calculated using the equation h = -16t² + 104t.

The vertex of the parabolic function will give the value of the highest point of the rocket. The x-coordinate of the vertex gives us the time at which the rocket reaches its maximum height.

The x-coordinate of the vertex can be found using the formula: x = -b / 2a, the coefficient of the t² term is a and coefficient of the t term is b.

In this case, a = -16 and b = 104, so the x-coordinate of the vertex is,

x = -b / 2a

= -104 / (2*(-16))

= 3.25

Therefore, the rocket is at its highest point 3.25 seconds after launch.

The open spaces in sculpture are called negative spaces.

In sculpture, negative space refers to the empty or void areas that exist between and around the solid forms or objects. It is the space that surrounds and defines the positive elements or shapes in a sculpture. Negative space plays a crucial role in creating balance, contrast, and harmony in sculptural compositions.

When an artist sculpts an object, they not only consider the physical mass and volume of the object itself but also pay attention to the spaces that are created as a result. These empty spaces are as important as the solid forms and contribute to the overall aesthetic and visual impact of the sculpture. By carefully manipulating the negative spaces, artists can enhance the perception of the positive elements and create a sense of depth, movement, and tension within the artwork.

In contrast, positive space refers to the solid or occupied areas in a sculpture, while the terms "literal" and "linear" do not specifically relate to the concept of open spaces in sculpture. Therefore, the correct answer is negative spaces.

Yes, i agree with hector. The polygon in above figure is irregular due to unequal side lengths and Hector also states that it is not regular or irregular.

A polygon is a 2-D geometric figure that has a finite number of sides. The sides are equal in length. It is a closed shape formed by end to end joining of straight line segments. For examples of regular polygons are square, rhombus, equilateral triangle, etc.

An irregular polygon, also called a non-regular polygon. It is a shape that does not have all sides of equal length and all angles of equal. For examples scalene triangle, rectangle, kite etc. are examplses of irregular polygon.

Now, we have a polygon present in above figure. As we see that this figure has 8 sides and length of one side is equal to its opposite side, but all sides are not equal length. So, it is an irregular polygon. Hector also states that above figure is irregular polygon. Hence, i agree with hector.

The resulting dimensions of the acetal disk under a 30-kN load cannot be calculated without additional information about the material properties and deformation behavior.

To calculate the resulting dimensions of the acetal disk, we need to know its properties such as its modulus of elasticity, Poisson's ratio, and yield strength. Without this information, it is not possible to accurately calculate the resulting dimensions.

However, assuming that the acetal disk behaves as a linearly elastic material and that it does not yield under the applied load, we can use the following formula to calculate the resulting dimensions:

δ = PL/(Et^3π/16)

where δ is the deflection of the disk, P is the applied load, L is the diameter of the disk, t is the thickness of the disk, E is the modulus of elasticity, and ν is Poisson's ratio.

Assuming that the acetal disk has a modulus of elasticity of 2.8 GPa and a Poisson's ratio of 0.35, we can calculate the deflection of the disk as follows:

δ = (30 kN)(25 mm)/[(2.8 GPa)(5 mm)^3π/16] ≈ 0.021 mm

Therefore, the resulting dimensions of the acetal disk would be:

Diameter: 25 mm + 2δ ≈ 25.042 mm

Thickness: 5 mm - δ ≈ 4.979 mm

Note that these calculations are based on several assumptions and simplifications, and the actual resulting dimensions of the acetal disk may differ from these estimates. It is always important to consider the specific properties and behavior of the material being used in any mechanical loading device.
