The path of a particle is defined by s(t) = t^4/4 - t^3+t^2, t less than or equal to 0. when is the particle moving from left to right
]The particle is moving from left to right for t > 2 or 0 < t < 1.5.
The path of a particle defined by s(t) = t⁴/4 − t³ + t², t ≤ 0. The particle is moving from left to right when its velocity is positive.
The velocity of the particle is given by the first derivative of its position function, which is s'(t) = t³ − 3t² + 2t. To find when the particle is moving from left to right, we need to find when its velocity is positive.
The particle is moving from left to right when its velocity is positive, which occurs when t > 2 or 0 < t < 1.5. Therefore, the particle is moving from left to right for t > 2 or 0 < t < 1.5.
The velocity function, s'(t) = t³ − 3t² + 2t, can be factored as s'(t) = t(t − 1)(t − 2).
This means that the velocity of the particle is 0 when t = 0, t = 1, and t = 2.
When t < 0, the velocity is negative because all three factors in the velocity function are negative. When 0 < t < 1, only one factor is negative (t − 2), so the velocity is positive.
When 1 < t < 2, two factors are negative (t − 1) and (t − 2), so the velocity is negative. When t > 2, all three factors are positive, so the velocity is particle .

The length of one side of the equilateral triangle in terms of x is 6x.
To find the length of one side of the equilateral triangle in terms of x, we need to consider the perimeter of both the rectangle and the equilateral triangle.
The perimeter of a rectangle is given by the formula:
Perimeter of rectangle = 2(length + width)
In this case, the length of the rectangle is 7x cm, and the width is 2x cm. Substituting these values into the formula, we have:
Perimeter of rectangle = 2(7x + 2x) = 2(9x) = 18x
We are told that the equilateral triangle has the same perimeter as the rectangle.
Since an equilateral triangle has all sides equal, the perimeter can be calculated by multiplying the length of one side by 3.
Therefore, we have:
Perimeter of equilateral triangle = 3(side length)
Since the perimeter of the equilateral triangle is equal to the perimeter of the rectangle (18x), we can set up the equation:
3(side length) = 18x
Dividing both sides of the equation by 3, we get:
side length = 6x
Hence, the length of one side of the equilateral triangle in terms of x is 6x.

Find the length of the third side. If necessary, write in simplest radical form.
5,
√106
Answer:
Length of third side = 9
Step-by-step explanation:
Because this is a right triangle, we can find the length of the third side using the Pythagorean theorem, which uses the equation a^2 + b^2 = c^2, where
a and b are the lengths of the shortest sides called legs,and c is the length of the longest side called the hypotenuse (always opposite the right angle).Thus, we can plug in 5 for a and √106 for c to find b, the length of the third side:
Step 1: Plug in 5 for a and √106 for for c. Then simplify:
5^2 + b^2 = (√106)^2
25 + b^2 = 106
Step 2: Subtract 25 from both sides:
(25 + b^2 = 106) - 25
b^2 = 81
Step 3: Take the square root of both sides to find b, the length of the third side:
√(b^2) = √81
b = ± 9
Taking the square root of a number always gives both a positive and negative answer since squaring both a positive and negative answer yields a positive answer: Example: 4^2 = 16 and (-4)^2 = 16.However, we can't have a negative side length so the third side is 9 units.

Prompt: The following four images show several steps in a visual proof of the Pythagorean Thoerem.
1. Choose an image (2,3, or 4) and answer the questions.
A. How does this image change from the previous image?
For example, if you choose image three, describe what transformations were used to get image two.
B. Choose one to figure in your image, and explain how the length of the figure are related to the figure in image one. For example, if you choose figure 5 in image three, describe how its lengths are related to the figure in image one.
C. How does the length of the figure you describe in 1b relate to the Pythagorean Theorem? For example, if you describe figure 5 in image three, explain how it’s links, relate to a^2+b^2 = c^2.
2. How does the visual proof demonstrate the Pythagorean Theorem? Hint: describe how the figures labeled 5 through 9 related to figures two and 10 an image 4.
The area of the larger square is equal to the sum of the areas of the two smaller squares. In image 3, the smaller squares are replaced by rectangles with the same areas, and in image 4 these rectangles are rearranged to form the same square as in image 2.
1. Image 2A. Image 2 is formed by rotating image 1, that is, the angle and lengths of the legs stay the same, only the position of the triangle changes.
Image 2 is formed from image 1 by rotating the right-angled triangle clockwise about point B through the angle of 90°. B. The lengths of the triangle in image 2 are related to the lengths of the triangle in image 1 through the Pythagorean Theorem.
In image 1, a = 4 and b = 3, so [tex]c^2 = a^2 + b^2 = 4^2 + 3^2 = 16 + 9 = 25[/tex]. Thus, c = 5.
Since image 2 is just a rotation of image 1, the lengths of the sides remain the same, that is, a = 4, b = 3, and c = 5. C. The length of the hypotenuse of the triangle in image 2 is c = 5, which is the same as the hypotenuse of the triangle in the image.
1. This verifies the Pythagorean Theorem, which states that the sum of the squares of the two legs of a right triangle is equal to the square of the hypotenuse.
That is, [tex]a^2 + b^2 = c^2[/tex]; where a, b, and c are the lengths of the legs and hypotenuse of the triangle.
2. The visual proof demonstrates the Pythagorean Theorem by showing that the sum of the areas of the squares constructed on the legs of a right triangle is equal to the area of the square constructed on the hypotenuse of the triangle.
Image 2 shows a right triangle with legs of length 3 and 4 units and a hypotenuse of length 5 units. Squares are constructed on each of the sides of the triangle, and the areas of these squares are compared.
The smaller squares on the legs of the triangle have areas of 9 and 16 square units, respectively, while the larger square on the hypotenuse of the triangle has an area of 25 square units.
Thus, the area of the larger square is equal to the sum of the areas of the two smaller squares. In image 3, the smaller squares are replaced by rectangles with the same areas, and in image 4 these rectangles are rearranged to form the same square as in image 2. This demonstrates that the Pythagorean Theorem holds true for all right triangles.

How to find the sum of the first 9 termsGiven data
3, 15/4, 75/16, ...
To find the sum of the first 9 terms of the series, we'll need to find a pattern and then use the formula for the sum of a geometric series. The series you provided seems to be a geometric series with a common ratio of 5/4.
The first term (a₁) is 3, and the common ratio (r) is 5/4.
The formula for the sum of a geometric series is given by:
Sum = a₁ * (1 - rⁿ) / (1 - r),
where n is the number of terms.
Plugging in the values, we have:
Sum = 3 * (1 - (5/4)⁹) / (1 - 5/4).
Sum ≈ 3 * (1 - 1.953125) / (1 - 1.25)
≈ 3 * (-0.953125) / (-0.25)
≈ 3 * 3.8125
≈ 11.4375.
Rounding to the nearest integer = 11

Calculate the area of the trapezium.
10 cm
9 cm
8 cm
Not to scale
Answer:To calculate the area of a trapezium, we need the lengths of its parallel sides (the bases) and the distance between them (the height). Given that the trapezium is not to scale, we assume the 10 cm, 9 cm, and 8 cm measurements refer to the lengths of the three sides.
Let's label the trapezium as ABCD, where AB is the longer base, CD is the shorter base, and AD and BC are the non-parallel sides.
Given:
AB = 10 cm (longer base)
CD = 8 cm (shorter base)
AD = 9 cm (non-parallel side)
To calculate the area of the trapezium, we can use the formula:
Area = (1/2) * (AB + CD) * height
However, the height is not given directly. We can calculate it using the Pythagorean theorem by considering triangle ADB.
Using the Pythagorean theorem, we have:
AD^2 = AB^2 - BD^2
Rearranging the equation to solve for BD:
BD^2 = AB^2 - AD^2
BD^2 = 10^2 - 9^2
BD^2 = 100 - 81
BD^2 = 19
BD = √19 cm (approx.)
Now that we have BD, we can use it as the height of the trapezium.
Area = (1/2) * (AB + CD) * height
Area = (1/2) * (10 + 8) * √19
Area = (1/2) * 18 * √19
Area = 9 * √19 cm² (approx.)
Therefore, the area of the trapezium is approximately 9√19 cm².
Step-by-step explanation:
A company is tracking a number of complaints received on its website. During the first 4 months, they
record the following numbers of complaints: 18, 22, 26, 30. What is the explicit rule for the number of
complaints they will received in the nth month? After how many months will the complaints reach 126?
To find the explicit rule for the number of complaints received in the nth month, we can observe the pattern in the given data. The number of complaints increases by 4 each month.
So, we can write the explicit rule as follows:
Number of complaints (n) = 18 + 4(n - 1)
To find the number of months it will take for the complaints to reach 126, we can set up an equation:
18 + 4(n - 1) = 126
Simplifying the equation:
4(n - 1) = 126 - 18
4(n - 1) = 108
n - 1 = 27
n = 28
Therefore, it will take 28 months for the number of complaints to reach 126.
I'll give you brainliest! What are the odds of winning a game, if the probability of winning the game is 4/10?
Remember:
The probability of an event happening is the fraction: favorable outcomes/total outcomes.
The odds of an event happening treats the event as a win. The odds are given by the ratio: wins: losses
4:6
10:4
13:1
14:4
Answer:
Odds = 4 : 6
Step-by-step explanation:
We have a game where the chance of winning it is only 4 out of 10. Therefore, the chance of losing is 10 - 4 = 6.
So,
wins = 4
loses = 6
total = 10
Now,
Odds = wins : loses
=》Odds = 4 : 6

Which equation has no solution?
helloos, i think the answer is the last option "4 + 6(2 + x) = 2(3x + 8)" because 4 + 6(2+x) = 6x + 16 and 2(3x + 8) = 6× + 16 as well. so, 6x + 16 = 6x + 16 has no solution because 0x = 0. therefore, x has no solution. I hope this helps you to understand it a little
whats the range and funcion
The range refers to the spread or Variation of values in a dataset or the output values of a function. A function is a mathematical relation that assigns unique output values to input values.
To clarify, are you referring to finding the range of a dataset and describing what a function is? If so, I can provide an explanation for both.
The range is a concept in mathematics that refers to the set of all possible output values of a function or a dataset. It represents the spread or variation of the values in the dataset or the function's output. In simple terms, the range is the difference between the maximum and minimum value.
For example, let's say we have a dataset {2, 4, 6, 8, 10}. The minimum value in this dataset is 2, and the maximum value is 10. Therefore, the range would be 10 - 2 = 8. So, the range of this dataset is 8.
On the other hand, a function is a relation between a set of inputs (called the domain) and a set of outputs (called the range). It assigns each input value to a unique output value. Functions are often represented by equations or formulas. They are widely used in mathematics to model various relationships and phenomena.
For instance, consider the function f(x) = 2x + 3. This function takes an input value x, multiplies it by 2, and then adds 3 to it. The output value, represented as f(x), is the result of this operation. So, if we input x = 2 into the function, we get f(2) = 2(2) + 3 = 7.
Functions can have different forms and properties, such as linear, quadratic, exponential, etc. They can be used to describe real-world situations, solve problems, and analyze data.
In summary, the range refers to the spread or variation of values in a dataset or the output values of a function. A function is a mathematical relation that assigns unique output values to input values.
