Answers
The vertex is (-1,0), range is (-inf,0], increasing on (-inf,-1), decreasing on (1,inf)
The key aspects of the function [tex]f(x) = - x^2 - 2x - 1[/tex] are as follows:
Vertex: The vertex of a quadratic function is the point where the function changes from increasing to decreasing, or vice versa. To find the vertex, we can complete the square or use the vertex formula. In this case, the vertex is (-1,0).
Range: The range of a function is the set of all possible output values. Since the leading coefficient in f(x) is negative, the parabola opens downwards, so the range is all numbers less than or equal to 0, or (-inf,0].
Increasing/Decreasing: A quadratic function is increasing to the left of its vertex and decreasing to the right of its vertex. Therefore, f(x) is increasing on (-inf,-1) and decreasing on (-1,inf).
Domain: The domain of a function is the set of all possible input values. For quadratic functions, the domain is all real numbers, so the domain of f(x) is all real numbers.
Therefore, The vertex is (-1,0), range is (-inf,0], increasing on (-inf,-1), decreasing on (1,inf).

If you place a 45-foot ladder against the top of a 36-foot building, how many feet will the bottom of the ladder be from the bottom of the building?
Using pythagorean theorem
Answers
The bottom of the ladder will be 27 feet from the bottom of the building.
To find the distance from the bottom of the ladder to the bottom of the building, we can use the Pythagorean theorem, which states that in a right triangle, the square of the length of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the lengths of the other two sides.
In this case, the ladder forms the hypotenuse, and the building forms one of the other sides of the right triangle. Let's denote the length from the bottom of the ladder to the bottom of the building as x.
According to the Pythagorean theorem:
[tex]\[ \text{Hypotenuse}^2 = \text{Adjacent side}^2 + \text{Opposite side}^2 \][/tex]
Given:
- Length of the ladder (hypotenuse) = 45 feet
- Height of the building (opposite side) = 36 feet
We need to find the length of the adjacent side (the distance from the bottom of the ladder to the bottom of the building).
[tex]\[ 45^2 = x^2 + 36^2 \][/tex]
2025 = [tex]x^2[/tex] + 1296
[tex]x^2[/tex] = 2025 - 1296
[tex]x^2[/tex] = 729
x = [tex]\sqrt{729}[/tex]
x = 27
A copy machine makes 36 copies per minute. How long does it take to make 135 copies
Answers
Final answer:
It takes 3.75 minutes for a copy machine that makes 36 copies per minute to make 135 copies.
Explanation:
To calculate how long it takes to make 135 copies with a machine that copies at the rate of 36 copies per minute, you can use a simple division. First, divide the total number of copies needed by the number of copies the machine can make per minute.
So, the calculation would be: 135 copies divided by 36 copies per minute = 3.75 minutes.
Therefore, it would take 3.75 minutes for the copy machine to make 135 copies.

Find the coordinates of quadrilateral V' W' X' Y' after a dilation with the scale factor of 2. Original coordinates: V(6, 2), W(–2, 4), X(–3, –2), Y(3, –5), scale factor of 2
Answers
The new coordinates after a dilation with scale factor 2 are: V'(12, 4), W'(-4, 8), X'(-6, -4), Y' (6, -10). The new coordinates are calculated by multiplying both the x and y coordinates of the original points by the scale factor.
Explanation:Dilation is a transformation that alters the size of the figure without changing its shape. It's accomplished by multiplying the original coordinates of the vertices by a specified scale factor.
The original coordinates of quadrilateral VWXY are V(6, 2), W(–2, 4), X(–3, –2), and Y(3, –5). The scale factor given is 2. Let's find the coordinates of each point after dilation.
1. First, we'll start with point V. Its coordinates are (6,2). After dilation with a scale factor of 2, we multiply each coordinate by the scale factor. The new coordinates are (6 × 2, 2 × 2) which gives us (12, 4).
2. The coordinates of point W are (–2, 4). After dilation, we obtain the new coordinates as (–2 × 2, 4 × 2), which gives us (–4, 8).
3. Now we move onto point X. Its coordinates are (–3, –2). After dilation, the new coordinates become (–3 × 2, –2 × 2), which is (–6, –4).
4. Lastly, we have point Y. Its coordinates are (3, –5). After dilation, the new coordinates become (3 × 2, –5 × 2), which gives us (6, –10).
Therefore, the coordinates of the quadrilateral V'W'X'Y' after dilation with the scale factor of 2 are V'(12, 4), W'(–4, 8), X'(–6, –4), and Y'(6, –10).

Given: 2(10 – 13x) = -34x + 60
Step 1: Distribute 20 – 26x = -34x + 60
Step 2: Addition property of Equality -26x = -34x + 80
Step 3: Addition property of Equality 8x = 80
Step 4: Division Property of Equality x = 10
Answers
You subtract 20. To 60, not add
Answer:
Step 2 has an error
Step-by-step explanation:
Given equation,
2(10 - 13x) = -34x + 60
By distributive property,
20 - 26x = -34x + 60
Now, we need to isolate x on the left side of the equation,
For this we need to eliminate constant term from the left side,
20 will be eliminated by subtracting 20 from both sides ( subtraction property of equality )
I.e. Step 2 has an error,
We need to use subtraction property of equality instead of using addition property of Equality,
Note : The correct steps would be,
Step 2 : 20 - 26x = -34x + 60 ( Subtraction property of equality )
Step 3 : 8x = 40 ( addition property of Equality )
Step 4 : x = 5 ( Division Property of Equality )

There are 240 students on Misty’s school. This is 5% of the total students in the school district. How many students are there in the school district?
Answers
To find the total number of students in the school district, set up a proportion using the given information. Cross multiply to solve for x.
Explanation:To find the total number of students in the school district, we can set up a proportion using the given information. If 240 students represent 5% of the total students, we can write the proportion as:
x/240 = 100/5
Cross multiplying, we get:
x = (240 * 100) / 5
Simplifying, we find:
x = 4800
Therefore, there are 4800 students in the school district.
To find the total number of students in the school district, divide the number of students at Misty's school (240) by the percentage they represent (5%), resulting in a total of 4800 students in the school district.
Explanation:If Misty's school has 240 students, which represents 5% of the total students in the school district, we can calculate the total number of students in the school district using percentages and equivalent fractions. We can set up an equation where 240 students is 5% of the total number of students (let's call this total x).
The equation is 240 = 0.05 * x. To find x, divide 240 by 0.05, which gives us x = 240 / 0.05. This calculation yields x = 4800. Therefore, there are 4800 students in the school district.

Saturn is located at a distance of 9.54 AU from the Sun what is its orbital period
Answers
Answer:
C. 29.46 years
Step-by-step explanation:
The other person is correct, thank you.
Saturn's mean distance from the Sun at 9.54 AU gives it an orbital period of about 29.46 Earth years.
The student is asking about the orbital period of Saturn based on its average distance from the Sun, expressed in astronomical units (AU). According to Kepler's third law of planetary motion, there is a relationship between the orbital period of a planet and its average distance from the Sun. For Saturn, its mean distance from the Sun is approximately 9.54 AU, and its orbital period is roughly 29.46 Earth years.
Kepler's third law states that the square of the orbital period of a planet is directly proportional to the cube of the semi-major axis of its orbit. This can be expressed mathematically as p² = a³, where p is the orbital period in Earth years and a is the semi-major axis in AU. By checking Saturn's given values for p² (29.46 * 29.46 = 867.9) and a³ (9.54 * 9.54 * 9.54 = 868.3), we can see that Saturn's data approximates the relation of Kepler's third law effectively, confirming that an orbital period of 29.46 years for Saturn's distance from the Sun is consistent.
