Which of the following is the quotient of the rational expressions shown
below? Make sure your answer is in reduced form.
7x² /2x +6 divided by 3x -5/ x+3
Answer:
(7x² / 6x - 10)
Step-by-step explanation:
To divide rational expressions, we flip the second fraction (the divisor) and multiply it with the first fraction (the dividend). Then we simplify the resulting expression, if possible.
So,
(7x² /2x +6) ÷ (3x -5/ x+3)
= (7x² /2x +6) * (x+3/3x -5)
= 7x²(x+3) / 2(x+3)(3x -5)
= 7x² / 6x - 10
Therefore, the quotient of the given rational expressions is (7x² / 6x - 10), which cannot be further reduced.

A. They are one-dimensional
B. They connect two endpoints
Both statements A and B are true about line segments. Line segments are one-dimensional figures that have two endpoints and connect them with a straight path.
Statement C is not true. Line segments do not have a unit of measure on their own, but their length can be measured using a unit of measure such as inches, centimeters, or meters.
Statement D is not true either. Line segments are flat, one-dimensional objects and cannot grow to become three-dimensional objects. However, multiple line segments can be connected to form a three-dimensional object, such as a cube or pyramid.

A circle with center O (0,0) has point B (4,5) on its circumference, which is joined by a line to O.
What is the general form of the equation for the given circle centered at O(0, 0)?
A.
x2 + y2 + 41 = 0
B.
x2 + y2 − 41 = 0
C.
x2 + y2 + x + y − 41 = 0
D.
x2 + y2 + x − y − 41 = 0
Answer:
B is the correct answer
Step-by-step explanation:
The general form of the equation for a circle centered at the origin (0, 0) is x^2 + y^2 = r^2, where r is the radius of the circle. The radius can be calculated as the distance between the center O (0, 0) and point B (4, 5) on its circumference using the distance formula: r = sqrt((x2 - x1)^2 + (y2 - y1)^2) = sqrt((4 - 0)^2 + (5 - 0)^2) = sqrt(16 + 25) = sqrt(41). Therefore, the equation for the given circle centered at O (0, 0) is x^2 + y^2 = 41. The correct answer is B. x^2 + y^2 − 41 = 0.

5) A rectangle has an area of 30x2y. The length of one of its sides is 6xy. What is its width?
The width of the rectangle is 5.
What is area of rectangle?The area of a rectangle is given by the formula:
Area = Length x Width
where Length and Width are the measurements of the two adjacent sides of the rectangle.
For example, if a rectangle has a length of 6 units and a width of 4 units, then its area would be:
Area = Length x Width
Let's start by using the formula for the area of a rectangle:
Area = Length x Width
We are given that the area of the rectangle is 30xF²y and that one of its sides (length) is 6xy. Substituting these values into the formula, we get:
30x²y = (6xy) x Width
Simplifying the right-hand side by multiplying 6xy by Width, we get:
30x²y = 6x²y x Width
Dividing both sides by 6x²y, we get:
Width = 30x²y / 6x²y
Simplifying the right-hand side by canceling out the common factors of 6, x², and y, we get:
Width = 5
Therefore, the width of the rectangle is 5.

What is the result when the number 59 is decreased by 3.9%? 59
Answer:
Step-by-step explanation:
To find the result when the number 59 is decreased by 3.9%, we need to first calculate what 3.9% of 59 is.
To do this, we can multiply 59 by 3.9% (or 0.039), which gives us:
59 x 0.039 = 2.301
This tells us that 3.9% of 59 is 2.301.
Next, we need to subtract 2.301 from 59 to get the final result:
59 - 2.301 = 56.699
Therefore, the result when the number 59 is decreased by 3.9% is 56.699. we could say that if you take 3.9% of 59 and subtract that amount from 59, the answer is 56.699.

Given vectors u = ⟨3, 4⟩ and v = ⟨4, 3⟩, what is the measure of the angle between the vectors?
The measure of the angle between the vectors is approximately 41.41 degrees.
Define Angle and its properties ?When we join two line segments at a single point, an angle is formed, or we can say, an Angle is a combination of two line segments at a common endpoint. This common point is called Vertex of the angle and the two line segments are sides or arms of the angle formed.The sum of all the angles of a triangle (of all types) is equal to 180°. The sum of the length of the two sides of a triangle is greater than the length of the third side. In the same way, the difference between the two sides of a triangle is less than the length of the third side.
To find the angle between two vectors, we can use the dot product formula:
cos(theta) = (u · v) / (|u| |v|)
where u · v is the dot product of u and v, and |u| and |v| are the magnitudes of u and v, respectively.
First, let's calculate the dot product of u and v:
u · v = 3 × 4 + 4 × 3 = 24
Next, we need to calculate the magnitudes of u and v:
|u| = √(3² + 4²) = 5
|v| = √(4² + 3²) = 5
Now we can plug these values into the formula for cosine:
cos(theta) = (u · v) / (|u| |v|)
cos(theta) = 24 / (5 * 5)
cos(theta) = 24 / 25
To find the measure of the angle, we need to take the inverse cosine (or arccos) of this value:
theta = arccos(24/25)
theta ≈ 0.7227 radians or 41.41 degrees
So the measure of the angle between the vectors is approximately 41.41 degrees.

The values of x and y that satisfy the system of equations are x = 8 and y = 4.
What are the values of x and yTo solve for the values of x and y in the system of equations:
x + y = 12
2x + 5y = 36
We can use the method of substitution. Solving the first equation for x, we get:
x = 12 - y
We can substitute this expression for x into the second equation and solve for y:
2(12 - y) + 5y = 36
24 - 2y + 5y = 36
3y = 12
y = 4
Now that we know y is 4, we can substitute this value back into the first equation and solve for x:
x + 4 = 12
x = 8
Therefore, the values of x and y that satisfy the system of equations are x = 8 and y = 4.

The function f(x) = 7x + 1 is transformed to function g through a horizontal compression by a factor of What is the equation of function g?
Substitute a numerical value for k into the function equation.
Answer:
The equation of function g after horizontal compression by a factor of 3 is:
g(x) = 7(3x) + 1 = 21x + 1
To substitute a numerical value for k into the function equation, we need to know the value of k. It is not given in the question, so we cannot provide a numerical answer.
Step-by-step explanation:
When a function is horizontally compressed by a factor of k, we divide the input (x) by k to obtain the new input for the transformed function.
The equation for the horizontally compressed function is:
g(x) = f(x/k)
Substituting f(x) = 7x + 1, we get:
g(x) = 7(x/k) + 1
Simplifying, we get:
g(x) = (7/k)x + 1
Thus, the equation for the transformed function g is obtained by replacing k with the given compression factor.
For example, if the compression factor is 3, then:
g(x) = (7/3)x + 1
And to substitute a numerical value for k, we need to know the value of k. If k = 2, for example, then:
g(x) = (7/2)x + 1
Find the length of ST.

Describe Tangents?In geometry, a tangent is a line that touches a curve at a single point, without crossing over the curve at that point. This point of contact is called the point of tangency.
For example, in a circle, a tangent is a line that intersects the circle at exactly one point. The tangent line is perpendicular to the radius of the circle at the point of tangency.
Tangents are important in geometry because they allow us to find the slope of a curve at a specific point. The slope of the tangent line at a point on a curve is equal to the derivative of the function representing the curve at that point.
To find the length of ST, we need to find the length of SR and add it to the length of RT.
Using the tangent-tangent theorem, we know that RP is perpendicular to RT at point R. Therefore, angle RPT is a right angle.
We can use the Pythagorean theorem to find the length of RT. Let's call the length of RP "a" and the length of PT "b". Then, we have:
a² = (x+6)² + b² (from right triangle PQR)
a² = (2x-9)² + (b+3)² (from right triangle PSR)
Setting these two equations equal to each other, we have:
(x+6)² + b² = (2x-9)² + (b+3)²
Expanding and simplifying, we get:
x² - 24x + 90 = 0
Solving for x using the quadratic formula, we get:
x = (24 ± √(24² - 4190)) / (2*1) = 15 or 6
Since x cannot be negative, we take x = 15.
Now we can use the Pythagorean theorem to find the length of SR:
a² = (2x-9)² + (b+3)²
a² = (2*15-9)² + (b+3)²
a² = 276 + (b+3)²
We also know that SR = 3, so:
3² = (b+3)²
9 = b² + 6b + 9
b² + 6b - 0 = 0
Solving for b using the quadratic formula, we get:
b = (-6 ± √(6² - 410)) / (2*1) = -3 or 0
Since b cannot be negative, we take b = 0.
Therefore, we have:
a² = (x+6)² + b²
a² = (15+6)² + 0²
a² = 441
So, RT = a = √(441) = 21.
Finally, we have:
ST = SR + RT = 3 + 21 = 24.
Therefore, the length of ST is 24.

How does controlled destruction make it easier to build new buildings?
Controlled destruction, also known as selective demolition or deconstruction, involves carefully dismantling a building or structure in order to salvage and reuse as many materials as possible. This process can make it easier to build new buildings in several ways:
Minimizes waste: By salvaging and reusing materials from the old building, controlled destruction minimizes the amount of waste generated during the demolition process. This can reduce the need for new materials, which can be costly and time-consuming to source and transport.
Reduces environmental impact: Controlled destruction can also be more environmentally friendly than traditional demolition methods, as it produces less waste and pollution. This can help to minimize the impact on the local environment and reduce the carbon footprint of the construction project.
Provides access to reusable materials: Salvaging materials from the old building can also provide access to high-quality, durable materials that can be used in the construction of the new building. This can save time and money on sourcing new materials, and can also provide an opportunity to incorporate unique and interesting architectural features.
Helps to preserve historical buildings: In some cases, controlled destruction can be used to preserve historical buildings or structures by carefully dismantling them and reusing the materials in a new context. This can help to maintain the cultural and historical significance of the original building, while still allowing for new development and construction in the area.
Overall, controlled destruction can make it easier to build new buildings by minimizing waste, reducing environmental impact, providing access to reusable materials, and helping to preserve historical buildings.

5.1
Step-by-step explanation:
x = x+10
6. 42
cross multiply
42x= 6x + 60
42x-6x =60
36x=60
x=1.7
3x= 3×1.7
=5.1
An experiment for which the two-sample independent t test will be employed uses one sample with N = 8 and a second sample with N = 12 to evaluate a new treatment. The t test for this experiment will have how many degrees of freedom?
The calculated degrees of freedom for the t-test is 18
The degrees of freedom (df) for an independent t-test with two samples can be calculated using the following formula:
df = (n1 + n2) - 2
Where n1 is the sample size of the first group and n2 is the sample size of the second group.
In this case, the first sample has N = 8 and the second sample has N = 12.
Therefore, the degrees of freedom for the t-test will be:
df = (8 + 12) - 2
df = 18
So the t-test for this experiment will have 18 degrees of freedom.
