Answer: X=10
m<UXV = 46 degrees
Step-by-step explanation:
Angle WXV is 90 degrees, We know this because Angle VXY is 90 degrees, so it is the same on the other side Angle WXV is split into two angles (WXU, and UXV) to find UXV we subtract 44 from 90, which is 46 Degrees, Now we know 5x-4 is equal to 46, 46+4 is 50, 50/5 is 10, so x is 10
The value of x is, 10
And, The value of angle ∠ UXV is, 46°
Given that;
Angle 44° and ∠ UVX is made a right angle.
Hence, We can formulate;
⇒ 44° + ∠ UVX = 90°
⇒ 44° + (5x - 4)° = 90°
⇒ 44 + 5x - 4 = 90
⇒ 5x + 40 = 90
⇒ 5x = 90 - 40
⇒ 5x = 50
⇒ x = 10
Hence, The value of angle ∠ UXV is,
⇒ ∠ UXV = 5x - 4
= 5 × 10 - 4
= 50 - 4
= 46°
Thus, The value of x is, 10
And, The value of angle ∠ UXV is, 46°

Find the eritical numbers, if any, the function \( f(x)=-x+\sin (2 x), 0 \leq x \leq \pi \). (Use symbolic notation and fractions where needed. Give your answer in the form of a comma separated list.
These are the Critical numbers of the function within the given interval.
Therefore, the answer is \(x=\frac{\pi }{6}, \frac{5 \pi }{6}\).
The Critical numbers of a function are the values of x that make the derivative of the function equal to zero. To find the eritical numbers of the given function, we need to find the derivative of the function and set it equal to zero.
The derivative of the function \(f(x)=-x+\sin (2 x)\) is \(f'(x)=-1+2\cos (2 x)\).
Setting the derivative equal to zero, we get:
\(-1+2\cos (2 x)=0\)
\(\cos (2 x)=\frac{1}{2}\)
Using the inverse cosine function, we get:
\(2 x=\cos ^{-1}\left(\frac{1}{2}\right)\)
\(2 x=\frac{\pi }{3}\) or \(2 x=\frac{5 \pi }{3}\)
Dividing both sides by 2, we get:
\(x=\frac{\pi }{6}\) or \(x=\frac{5 \pi }{6}\)
These are the Critical numbers of the function within the given interval.
Therefore, the answer is \(x=\frac{\pi }{6}, \frac{5 \pi }{6}\).

Answer:
72π-144 m²
Step-by-step explanation:
You want the area of a shaded region consisting of the overlap of two quarter circles in a 12 m square.
SegmentsIf we draw a diagonal from upper left to lower right through the figure, the shaded area is divided into two 90° segments of a circle of radius 12 m.
The formula for the area of a segment is ...
A = 1/2r²(θ -sin(θ))
where θ is the measure of the central angle.
For θ = π/2 radians, this is ...
A = 1/2r²(π/2 -1) . . . . . half the shaded area
Shaded areaThen the whole shaded area is ...
2 × 1/2r²(π/2 -1) = (12 m)²(π/2 -1) = 72π -144 m²
The area of the shaded region is 72π -144 m².
__
Additional comment
If we expand the shaded area formula, we get ...
A =1/2πr² -r²
This is recognizable as twice the area of a quarter circle, less the area of the square.

If the scale factor of a dilation is 8: 7, what kind of image does it create?
A dilation with a scale factor of 8:7 creates an image that is eight times larger than the original.
What is scale factor?A scale factor is a numerical value which is used to multiply or divide a given measurement. It is used to compare the sizes of two different objects, or to enlarge or reduce the size of an object. The scale factor can be used to calculate the area, perimeter, and volume of an object. For example, if an object is enlarged by a scale factor of 2, its area will increase by a factor of 4. Similarly, if an object is reduced by a scale factor of 0.5, its area will be reduced by a factor of 0.25.
This means that all of the points in the original image are moved away from the center of the dilation by a factor of eight. This creates an image that is eight times wider and seven times taller than the original. This type of dilation is also known as an enlargement. By enlarging the image, it is possible to see more detail and make the image easier to see. Additionally, it may also be possible to see features that were previously too small to be seen.

a. (12 points) Given the following matrix \( A \), compute \( A^{-1} \) using the row reduction method covered in class and discussion. (You may have already seen other methods for computing inverses
So, the inverse of \(A\) is:
\[A^{-1} = \left[\begin{array}{ccc}
a^{-1}_{11} & a^{-1}_{12} & a^{-1}_{13} \\
a^{-1}_{21} & a^{-1}_{22} & a^{-1}_{23} \\
a^{-1}_{31} & a^{-1}_{32} & a^{-1}_{33} \\
\end{array}\right]\]
This is how we can compute the inverse of a matrix using the row reduction method.
To compute \(A^{-1}\) using the row reduction method, we need to first set up an augmented matrix with \(A\) on the left and the identity matrix on the right. Then, we will use elementary row operations to reduce the left side of the matrix to the identity matrix, which will result in the inverse of \(A\) on the right side. Here are the steps:
1. Set up the augmented matrix:
\[\left[\begin{array}{ccc|ccc}
a_{11} & a_{12} & a_{13} & 1 & 0 & 0 \\
a_{21} & a_{22} & a_{23} & 0 & 1 & 0 \\
a_{31} & a_{32} & a_{33} & 0 & 0 & 1 \\
\end{array}\right]\]
2. Use elementary row operations to reduce the left side of the matrix to the identity matrix. For example, we can use the following operations:
- Multiply the first row by a constant to make the first element 1
- Subtract a multiple of the first row from the second and third rows to make the first element of those rows 0
- Repeat these steps for the second and third columns until the left side of the matrix is the identity matrix
3. Once the left side of the matrix is the identity matrix, the right side of the matrix will be the inverse of \(A\):
\[\left[\begin{array}{ccc|ccc}
1 & 0 & 0 & a^{-1}_{11} & a^{-1}_{12} & a^{-1}_{13} \\
0 & 1 & 0 & a^{-1}_{21} & a^{-1}_{22} & a^{-1}_{23} \\
0 & 0 & 1 & a^{-1}_{31} & a^{-1}_{32} & a^{-1}_{33} \\
\end{array}\right]\]
So, the inverse of \(A\) is:
\[A^{-1} = \left[\begin{array}{ccc}
a^{-1}_{11} & a^{-1}_{12} & a^{-1}_{13} \\
a^{-1}_{21} & a^{-1}_{22} & a^{-1}_{23} \\
a^{-1}_{31} & a^{-1}_{32} & a^{-1}_{33} \\

x
The approximate value of x to the nearest tenth of a degree is 36.9 degrees.
To find x to the nearest tenth of a degree, we can use trigonometric ratios for right triangles. First, we need to determine which trigonometric ratio to use based on the given information.
If we are given the opposite side and the adjacent side of the right triangle, we can use the tangent ratio:
tan(x) = opposite/adjacent
If we are given the opposite side and the hypotenuse, we can use the sine ratio:
sin(x) = opposite/hypotenuse
If we are given the adjacent side and the hypotenuse, we can use the cosine ratio:
cos(x) = adjacent/hypotenuse
Once we have determined the appropriate trigonometric ratio, we can plug in the given values and solve for x. To find x to the nearest tenth of a degree, we can use a calculator to find the approximate value of x and then round to the nearest tenth.
For example, if we are given a right triangle with an opposite side of 3 and an adjacent side of 4, we can use the tangent ratio to find x:
tan(x) = 3/4
x = tan^-1(3/4)
Using a calculator, we find that x is approximately 36.87 degrees. To the nearest tenth of a degree, x is approximately 36.9 degrees.
Therefore, the approximate value of x to the nearest tenth of a degree is 36.9 degrees.

From the given equation the value of r is 8.
A mathematical statement known as an equation is made up of two expressions joined together by the equal sign. A formula would be 3x - 5 = 16, for instance. When this equation is solved, we discover that the value of the variable x is 7.
To solve this equation for r, we need to isolate r on one side of the equation. First, we add 14 to both sides of the equation:
4r-14+14 = (9/4)r+14
4r = (9/4)r+14
Then, we subtract (9/4)r from both sides:
4r - (9/4)r = (9/4)r+14 - (9/4)r
(5/4)r = 14

tan^2 t/sec t = (sin^2 t/cos^2 t)/(1/cos t) = sin^2 t/cos t
Now we can subtract cos t from both sides of the equation:
sin^2 t/cos t - cos t = sec t - cos t
Next, we can multiply both sides of the equation by cos t to get rid of the fraction:
sin^2 t - cos^2 t = sec t*cos t - cos^2 t
Finally, we can use the Pythagorean identity sin^2 t + cos^2 t = 1 to simplify the left-hand side of the equation:
1 - cos^2 t - cos^2 t = sec t*cos t - cos^2 t
0 = sec t*cos t - 2*cos^2 t
22. cot^2 t/csc t = csc t-sin t
First, we can simplify the left-hand side of the equation by dividing cot^2 t by csc t. Remember that cot t = cos t/sin t and csc t = 1/sin t:
cot^2 t/csc t = (cos^2 t/sin^2 t)/(1/sin t) = cos^2 t/sin t
Now we can subtract sin t from both sides of the equation:
cos^2 t/sin t - sin t = csc t - sin t
Next, we can multiply both sides of the equation by sin t to get rid of the fraction:
cos^2 t - sin^2 t = csc t*sin t - sin^2 t
Finally, we can use the Pythagorean identity sin^2 t + cos^2 t = 1 to simplify the left-hand side of the equation:
1 - sin^2 t - sin^2 t = csc t*sin t - sin^2 t
0 = csc t*sin t - 2*sin^2 t
24. (1−sin θ)/cos θ = sec θ−tan θ
First, we can simplify the left-hand side of the equation by dividing 1-sin θ by cos θ:
(1−sin θ)/cos θ = (1/cos θ) - (sin θ/cos θ) = sec θ - tan θ
So the equation is already simplified and both sides are equal.
25. (sin t/csc t) + (cos t/sec t) = 1
First, we can simplify the left-hand side of the equation by dividing sin t by csc t and cos t by sec t. Remember that csc t = 1/sin t and sec t = 1/cos t:
(sin t/csc t) + (cos t/sec t) = (sin t/(1/sin t)) + (cos t/(1/cos t)) = sin^2 t + cos^2 t
Now we can use the Pythagorean identity sin^2 t + cos^2 t = 1 to simplify the left-hand side of the equation:
1 = 1
So the equation is already simplified and both sides are equal.

The top rectangle has a base b and a height h. The bottom rectangle has a base that is 1/3 of the length of the base of the top rectangle and a height that is 1/2 of the length of the height of the top rectangle. Devin writes the area of the smaller rectangle as the product 1/3 b • 1/2 h. Tracy rewrites this as 1/6 bh. Which of the students’ expressions makes it easier to see how the areas of the rectangles are related? Explain.
Tracy's expression makes it easier to see how the areas of the rectangles are related i.e. 1/6 bh.
What is a Rectangle?
The opposite sides of a quadrilateral are equal and parallel, and all the angles are equal. Around us, there are several rectangle-shaped items. Two dimensions, the length and breadth, define each rectangle shape. The width and length of a rectangle are its longer and shorter sides, respectively.
Dimensions of top rectangle :
base = b
height = h
So, area = b × h
Dimensions of bottom rectangle :
base = b/3
height = h/2
So, area = b/3 × h/2 = (b × h) 6
Hence, area of bottom rectangle is 1/6th of that top rectangle.
Devin writes the area of the smaller rectangle as the product 1/3 b • 1/2 h. Tracy rewrites this as 1/6 bh.
Hence, Tracy's expression represents more easier way to see how the rectangle's area is related.

Nora created a tiled mosaic for display in her local art museum. The numbers of tiles in the rows of the mosaic form an arithmetic sequence. The first row of the mosaic has 8 tiles and the second row has 12 tiles.
a. Write an explicit formula representing this sequence.
b. Determine the number of tiles in the 13th row.
a. The explicit formula for the sequence is: an = a + (n - 1)d
b. There are 56 tiles in the 13th row.
What is arithmetic sequence?
An arithmetic sequence is one in which each phrase grows by adding or removing a certain constant, k.
a. Let's denote the number of tiles in the first row as a, and the common difference between consecutive rows as d. Then, the number of tiles in the second row would be a + d, the third row would be a + 2d, and so on. Since the second row has 12 tiles and the first row has 8 tiles, we have:
a + d = 12
a = 8
We can solve this system of equations to find the value of d:
a + d = 12
8 + d = 12
d = 4
Therefore, the explicit formula for the sequence is:
an = a + (n - 1)d
where a = 8 and d = 4.
b. To find the number of tiles in the 13th row, we can plug in n = 13 into the formula:
a13 = 8 + (13 - 1)4
a13 = 8 + 48
a13 = 56
Therefore, there are 56 tiles in the 13th row.

Which equation shows the volume of the rectangular prism as a product of its edge lengths?
The equation that shows the volume of the rectangular prism as a product of its edge lengths is (5/3)(1/3)(2/3) = 10/27 in cube. Option 2 is the correct answer.
What is volume and how to calculate it?The quantity of space within a three-dimensional object is its volume. The fundamentals of such forms are described in our page on three-dimensional shapes. Calculating volume is probably not something you will do as frequently as calculating area in the real world.
Even so, it may still be significant. Knowing how to calculate volume will help you determine things like how much room you have for packing when moving house, how much room you need for an office, or how much jam you can put into a jar. It can also be helpful for deciphering what the media means when they discuss a dam's capacity or a river's flow.
The volume of the rectangular prims is given by the formula:
V = lwh
Substituting the values we have:
V = (5/3)(1/3)(2/3) = 10/27
Hence, the equation that shows the volume of the rectangular prism as a product of its edge lengths is (5/3)(1/3)(2/3) = 10/27 in cube. Option 2 is the correct answer.

(3, 5): Point A is located at the coordinates (3, 5) on the Cartesian plane, meaning it is 3 units to the right of the origin and 5 units above the origin.
What is Coordinate?Coordinates are points on a graph used to determine the position of a particular location. Coordinates can be expressed in two-dimensional (2D) or three-dimensional (3D) formats. In 2D, a point is determined by two numbers—its x and y values—which are the distances from the point to the origin along each axis. In 3D, an additional z-value is needed to indicate the distance from the origin along the third axis. Coordinates are used in a variety of applications, including navigation, mapping, surveying, and astronomy.
B. (2, -3): Point B is located at the coordinates (2, -3) on the Cartesian plane, meaning it is 2 units to the right of the origin and 3 units below the origin.
