The measure of the angle B is 55 degrees
How to determine the measure of the angle BFrom the question, we have the following parameters that can be used in our computation:
A triangle
On the triangle, we have the following readings:
Angle A = 53 degrees
Side AC = 13 units
Side AB = 15 units
To calculate the angle B, we start by calculating the measure of the length BC
This is represented using the following cosine law
BC = √(AC² + AB² - 2 * AC * AB * cos(A))
Substitute the known values in the above equation, so, we have the following representation
BC = √(13² + 15² - 2 * 13 * 15 * cos(53 degrees))
Evaluate
BC = 12.6
Using the sine law, we have
AC/sin(B) = BC/sin(A)
This gives
sin(B) = AC * sin(A)/BC
Substitute the known values in the above equation, so, we have the following representation
sin(B) = 13 * sin(53)/12.6
Evaluate
sin(B) = 0.8239890183
Take the arc sin
B = 55 degrees
Hence, the angle is 55 degrees

How to factor 75x^2-3
Answer: 75x^2-3 can be factored as (25x)^2 - 3 . The expression can be factored by taking the square root of the constant term and then using difference of squares.
In this case, the square root of -3 is not a real number, so it's not possible to factor it further.
So the final factored form of 75x^2-3 is (25x)^2 - 3.
Answer:
Step-by-step explanation:
75x^2-3 cannot be factored using integer numbers since it's a difference of squares. The expression 75x^2-3 is a binomial, not a trinomial. The difference of squares is a factoring pattern where you have a squared binomial subtracted from a constant.
75x^2-3 = 75x^2 -3x^2 = 72x^2 -3x^2 = (75-3)x^2 = 72x^2
So the factorization of 75x^2-3 is just 72x^2

Write the standard form of the quadratic function whose graph is a parabola with vertex (2,-1) and that passes through (5,2).
The standard form of the quadratic function whose graph is a parabola will be;
⇒ y = 1/3 (x² - 4x + 1)
What is Quadratic equation?An algebraic equation with the second degree of the variable is called an Quadratic equation.
Given that;
Vertex coordinate = (-3, 4)
And, A point on the graph = (0, 13)
Since, We know that;
The vertex form of a quadratic equation is given by;
⇒ y = a(x - h)² + k
Where h, k are the coordinates of the vertex.
Hence, At point (5, 2) at the vertex of (2, -1), we have;
⇒ 2 = a (5 - 2)² + (-1)
⇒ 2 = a × 9 - 1
⇒ 2 + 1 = 9a
⇒ 9a = 3
⇒ a = 3/9
⇒ a = 1/3
Since, The equation y = a(x - h)² + k is the vertex form,
Let us put the vertex values for h and k as well as the value of a to get the quadratic equation;
⇒ y = 1/3(x - 2)² - 1
⇒ y = 1/3 (x² + 4 - 4x) - 1
⇒ y = 1/3x² + 4/3 - 4/3x - 1
⇒ y = 1/3x² - 4/3x + 1/3

A company can choose to package 12 cans into 3 rows of 4 or 6 rows of 2 which packaging uses more material?
Why would a company choose to package 12 cans one way instead of another?
The packaging that uses more material is the packaging 2
The company's decision to package 12 cans one way instead of another is to save costHow to determine the packaging that uses more materialThe given parameters that can be used in our computation are:
Package = 12 cans Material 1 = 3 rows of 4 Material 2 = 6 rows of 2For a packaging to use more material, it must have a higher perimeter value
The perimeter is then calculated as
Perimeter = 2 * (Rows + Column)
When the values are substituted, we have the following equations
Material 1 Perimeter = 2 * (3 + 4)
Material 1 Perimeter = 14
Material 2 Perimeter = 2 * (6 + 2)
Material 2 Perimeter = 16

Yes, this is correct. An isometry is a transformation that preserves the sample size and shape of an object, meaning that the preimage and image are congruent.
An isometry is a transformation that preserves the size and shape of an object. This means that the preimage and image are congruent, meaning that they have the same size and shape. In order to determine if a transformation is an isometry, one must first identify the preimage and image. Once this has been done, the lengths of the corresponding sides must be compared in order to determine if they are congruent. If the lengths match, then the transformation is an isometry. Additionally, the angles of the preimage and image should also be compared to ensure that they are the same. If all the sides and angles match, then the transformation is an isometry.

Find the z value such that 86% of the standard normal curve lies between -z and z
The z-score is 1.0803.
Z-score is a statistical measurement that describes a value's relationship to the mean of a group of values. Z-score is measured in terms of standard deviations from the mean. If a Z-score is 0, it indicates that the data point's score is identical to the mean score. A Z-score of 1.0 would indicate a value that is one standard deviation from the mean. Z-scores may be positive or negative, with a positive value indicating the score is above the mean and a negative score indicating it is below the mean.
First, we need to find the α of the area we don't want, which would be:
α = 1 - 0.86 = 0.14
We know that the Standard Normal Distribution is symmetric, so we would divide our area we don't want to be on either side of our area, so we solve for:
[tex]\frac{\alpha }{2} = \frac{0.14}{2} = 0.07[/tex]
Now, it becomes easy to solve using the z-table.
The -z value is -1.0803 and the z value is 1.0803.
Hence, the z-score is 1.0803.

A number of squares are connected in a row to form a rectangle. The table shows the relationship between the number of squares, x, and the perimeter, y, of the rectangles they form. Select all the true statements about this relation.
The true statements are the equation of the function is y=4x+4, the relation is a function, the graph is linear.
The equation of the function start by calculating the slope (m)
The slope formula is used to calculate the inclination or steepness of a line. It finds application in determining the slope of any line by finding the ratio of the change in the y-axis to the change in the x-axis. The slope of a line is defined as the change in the "y" coordinate with respect to the change in the "x" coordinate of that line.
The formula to calculate slope is given as,
[tex]m=\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]where, m is the slope of the line, x1, x2 are the coordinates of the x-axis, and y1, y2 are the coordinates of the y-axis.
m=[tex]\frac{12-8}{2-1}=4[/tex]
m=4
The equation is then calculated as:
y=m[tex](x-x_{1})+y_{1}[/tex]So, we have
y=4(x-1)+8
y=4x-4+8
y=4x+4
Therefore, the equation is 4x+4. Hence the statement is true.
(b) The graph is nonlinear.
A linear function forms a straight line when it is plotted on a graph. A nonlinear function does not form a straight line (it is curved in some way). The slope of a linear function is constant, whereas the slope of a nonlinear function is continuously changingBecause of (a) above, the graph is linear.
(c) The relation is a function
A linear relation is a relationship or connection between two variables that will produce a straight line when graphed. There will be times when the data points are scattered and do not form an absolutely straight line. When it appears that the scattered points resemble a straight line,
Hence, the given relation is function then the statement is true.

Complete Question: What is the relationship between the number of squares, x, and the perimeter, y, of the rectangles they form?
Answer: The relationship between the number of squares, x, and the perimeter of the rectangles can be expressed as a y = 5.1%x. This equation states that for every one square, the perimeter will increase by 5.1%.
To calculate the perimeter of a rectangle with x number of squares, the following calculation can be used: y = 5.1%x = 0.051x. This equation can be rearranged to solve for x: x = y/0.051.
For example, if the perimeter of the rectangle is 10, the number of squares, x, can be calculated as follows: x = 10/0.051 = 196.08. This indicates that the rectangle will have 196 squares.
Therefore, the relationship between the number of squares, x, and the perimeter, y, of the rectangles they form can be expressed as y = 5.1%x, or x = y/0.051.

The length of a rectangle is 3 more than its width. The perimeter of the rectangle is
58 cm. What are the rectangle's dimensions?
Answer:
The perimeter of a rectangle is equal to the sum of all four sides. If the length of the rectangle is 3 more than the width, we can express the perimeter as 2width + 2(width+3). This simplifies to 2width + 2width + 6, which is equal to 58. This can be simplified to 4width + 6 = 58, or 4width = 52. Dividing both sides by 4 gives us width = 13.
Since the width of the rectangle is 13 cm, the length is 3 more than this, or 13+3 = 16 cm. So the dimensions of the rectangle are 13 cm by 16 cm.

The work done in lifting a bag of mulch was 504 Joules.
To find the amount of work done in this scenario, you can use the formula for work, which is work = force x distance x cos(theta), where force is measured in newtons (N), distance is measured in meters (m), and theta is the angle between the force and the displacement.
In this case, first, you lifted the bag of mulch 1.2 meters against gravity and the force applied is 45N and the displacement is 1.2m, the formula becomes:
work = force x distance x cos(theta) = 45 N x 1.2 m = 54 J
After, you carry the bag of mulch 10 meters, and the force applied is still 45N and the displacement is 10m, so the formula becomes:
work = force x distance x cos(theta) = 45 N x 10 m = 450 J
Therefore, the total amount of work done in lifting the bag of mulch 1.2 meters and carrying it at a distance of 10 meters is 54 J + 450 J = 504 J.

The Importance of Color Variety in Art: A Look at the Possibility of Painting a CubeWhen it comes to creating art, there is no denying the importance of color. It is one of the most powerful tools an artist has at their disposal, as it can be used to convey a wide range of emotions, ideas, and messages. Even a simple object such as a cube can be transformed into a work of art with the right colors. This essay will explore the potential of painting a cube with a variety of colors, and why it's important to use a variety of colors in artwork.
When it comes to painting a cube, one must choose colors that will create a harmonious yet interesting look. The colors should be chosen carefully because they will be the focus of the piece. A cube painted with only one color would be too dull and boring, while a cube painted with an array of colors will make it more visually appealing. To create a successful painting of a cube, one should use colors that contrast and complement each other. For example, a cube can be painted so that one face is blue, two faces are red, and three faces are green.

10x-9<-29 or 9x + 9 > 36
[tex]10x-9 < -29[/tex]
Add 9 to both sides:
[tex]10x-9+9 < -29+9[/tex]
[tex]10x < -20[/tex]
Divide both sides by 10:
[tex]\dfrac{10x}{10} < \dfrac{-20}{10}[/tex]
[tex]x < -2[/tex]
__________________________________________________________
[tex]9x + 9 > 36[/tex]
Subtract 9 from both sides:
[tex]9x+9-9 > 36-9[/tex]
[tex]9x > 27[/tex]
Divide both sides by 9:
[tex]\dfrac{9x}{9} > \dfrac{27}{9}[/tex]
[tex]x > 3[/tex]
__________________________________________________________
[tex]x < -2[/tex] or [tex]x > 3[/tex]
10x - 9 < -29
Add 9 to both sides:
10x - 9 + 9 < -29 + 9
10x < -20
Divide both sides by 10:
10x/10 < -20/10
x < -2
9x + 9 > 36
Subtract 9 from both sides:
9x + 9 - 9 > 36 - 9
9x > 27
Divide both sides by 9:
9x/9 > 27/9
x > 3
x < -2 or x > 3 would be your answer.
Hope this helps!
