The measure of the angle x is 22.5 degrees
Circle geometryCircle theorem includes the concept of tangents, sectors, angles, the chord of a circle and proofs.
A circle is the locus of all points in a plane which are equidistant from a fixed point
From the given diagram
arc AC = 180 - 135
arcAC = 45 degrees
Since the angle at the vertex is half the intercepted arc, hence;
x = 1/2(arc AC)
x = 1/2(45)
x = 22.5 degrees
Hence the measure of the angle x is 22.5 degrees

The domain of the function is -2 ≤ x < -5 and the range is -2 < y < 1
What is the domain of a function?The domain of the function is the set of input values of the graph
What is the range of a function?The range of a function is the set of output values of the graph.
How to determine the domain and the range?The graph represents the given parameters
On the graph, we have the following endpoints
Closed circle at (-2, -1)
Open circle at (-5, -2)
Maximum = (0, 1)
The domain
The definition of the domain implies that the domain of a function is the set of x values of the graph.
Recall that
Closed circle at (-2, -1)
Open circle at (-5, -2)
Maximum = (0, 1)
Remove the maximum
Closed circle at (-2, -1)
Open circle at (-5, -2)
Remove the y coordinates
So, we have
Closed circle at (-2)
Open circle at (-5)
Combine the x values
-2 ≤ x < -5
The range
The definition of the range implies that the range of a function is the set of y values of the graph.
Recall that
Closed circle at (-2, -1)
Open circle at (-5, -2)
Maximum = (0, 1)
Remove the smaller larger y value of the endpoints)
Open circle at (-5, -2)
Maximum = (0, 1)
Remove the x coordinates
So, we have
Open circle at (-2)
Maximum = (1)
Combine the y values
-2 < y < 1
Hence, the domain of the function is -2 ≤ x < -5 and the range is -2 < y < 1

Using limits and numeric value, we have that lim x -> 0 f(f(x)) is closest to:
c. 3.
What is f(f(x))?f(f(x)) is a composite function, hence:
For x = a, first we calculate the numeric value at x = a.Then we calculate the numeric value at x = f(a).What is a limit?A limit is the value that a function f(x) tends as x tends to a value. It there are no undetermined values, we can just verify the numeric value from the graph, but with undetermined values, there are multiple things to look at.
For this function, looking at the graph, we have that:
f(0) = 2, as when x = 0, f(x) = 2.Thus, lim x -> 0 f(f(x)) = lim x - > 2 f(x), because f(0) = 2.Both to the left of x = 2 and to the right of x = 3, from the graph, f(x) approaches 3, hence lim x - > 2 f(x) = 3.This means that option c is the closest approximation for the limit of the function.

Answers
The measure of angle J is 116°
What are linear pairs of angle?Linear pair of angles are angles formed when two lines intersect at a single point.
Angles are said to be linear if they are adjacent to each other with the intersection of the two lines.
Note that the sum of angles of a linear pair is equal to 180°.
From the information given, we have that;
Angle R = 3x - 5Angle J = 5x + 1But we have the expression as;
Angle R + Angle J = 180°
substitute the values into the equation
3x - 5 + 5x + 1 = 180°
collect like terms
8x - 4 = 180°
8x = 180 + 4
8x = 184
To determine the value of x, divide both sides by the 8
8x/8 = 184/8
Divide through
x = 23
But we have that;
Angle J = 5x + 1
Angle J = 5(23) + 1
Angle J = 115 + 1
Angle J = 116°
Thus, the measure of angle J is 116°

Podemos atribuir a incógnita x ao número de objetos que há na caixa. Assim, teremos as seguintes relações:
Metade dos objetos da caixa = 1/2x
Terça parte dos objetos da caixa = 1/3x
Portanto, o número de objetos que há na caixa será dado resolvendo a equação:
1/2x + 1/3x = 25
3/6x + 2/6x = 25
5/6x = 25
x = 25/(5/6)
x = 25 . (6/5)

Answers
The function rule for g(x) is (x₊6)² ₋ 5. According to the given data we apply the translations onto the graph and from the graph we determine the function of g(x).
Given, the function of f(x) = x²
The base graph is moved up or down in the y-axis direction when a graph is vertically translated. Each point on a graph is moved k units up the graph to translate it vertically. Shifting the f (x) k units vertically will allow you to sketch the equation g (x) = f (x) + k.
The graph of g(x) is f(x) translated to 6 units left and down 5 unit.
Draw the translations onto the graph. In the given graph provided, the yellow curve indicates the function g(x).

Answers
The percentage of the company’s employees are both female and over 6 feet tall is 3.75%
Let the total number of employees in the given company be x. So, the number of female employees in the company are : 75% × x
Number of female employees in company = 0.75x
Now, calculating number of female employees that over 6 feet tall = 0.75x × 5%
The number of female employees that over 6 feet tall = 0.0375x
Percentage of the company’s employees are both female and over 6 feet tall = percentage of female and tall employees ÷ total number of employees × 100
Percentage of the company’s employees are both female and over 6 feet tall = (0.0375x÷x)×100

What is the perimeter?A perimeter is a closed path that encompasses, surrounds, or outlines a two-dimensional shape or length. The circumference of a circle or an ellipse is its perimeter. There are several practical applications for calculating the perimeter.To find the dimensions:
First, we'll turn the information we have into an equation, where x is our unknown dimension.For this problem, it would be preferable if x equaled width.Let's write the equation down:X is the width, 2x + 2 is the length, and we multiply both by two because the field has two sides. Because the perimeter is 322, it will all add up to 322.2 × x + 2(2x +2) = 322Now, solve as follows:
2 × x + 2(2x + 2) = 3222x + 4x + 4 = 3226x + 4 = 3226x = 318x = 318 ÷ 6x = 53The width measures 53 yards.

What’s the domain and range?
Answers
Answer:
Domain: x > -4
Range: y > -1
Step-by-step explanation:
Domain is the points on the x axis that could be vaild for that line.
Range is the points on the y axis that could be valid for that line.
The range is: -4 < y < ∞
To find the domain, we need to look at the graph from a left-to-right standpoint (look at the x-axis). When doing so, the furthest point to the left we see is -4. Given that value, we put that as the first value. Then, we can put x since we’re looking at the x-axis. That would leave us with:
-4 < x < ?
Since there is an arrow on the farthest right side, we would put an infinity sign because it goes on forever. The same process is applied to the y-axis, and when doing so, we will get the same answer but with y.
