Answers
Answer:
n = -11
Step-by-step explanation:
Assuming you need to solve for n:
12 - n = 23 (Given)
-n = 11 (Subtract 12 on both sides)
n = -11 (Divide -1 on both sides)
Answer:
n = -11
Step-by-step explanation:
Since 2 negatives create a positive, 12 - -11 would turn into 12 + 11 = 23

In the diagram below, FC = 10.9,

length of EB. Round your answer to the
nearest tenth if necessary.

B
Answers
The length of EB is approximately 14.6 units when rounded to the nearest tenth.
To find the length of EB, we can use the property of similar triangles in this diagram. By looking at triangle DFE and triangle CFB, we can see that they are similar triangles.
Using the similarity ratio, we can set up the proportion:
DF / CF = DE / EB
Plugging in the given values, we have:
13.1 / 10.9 = 17.5 / EB
To find EB, we can cross-multiply and solve for EB:
13.1 * EB = 10.9 * 17.5
EB = (10.9 * 17.5) / 13.1
EB ≈ 14.6
Therefore, the length of EB is approximately 14.6 units when rounded to the nearest tenth.

Use the function below to find F(3)
F(x)=(1/5)^x
Answers
The value of the function F(3) will be 1/125. It is obtained by putting the value 3 in the place of x.
What is a function?A connection between independent variables and the dependent variable is defined by the function. Functions help to represent graphs and equations.
A function is represented by the two variables one is dependent and another one is an independent function. The relation between them is shown as y if dependent and x is the independent variable.
F(x)=(1/5)ˣ
F(3)=(1/5)³
F(3)=1/125

x≤-2 and x<-5
Answers
All the points less than -5 will be marked on the number line.
To represent the values of x where x ≤ -2 and x < -5 on a number line, we start by marking a point at -2 and shading everything to the left of it since x is less than or equal to -2. Next, we add another shading to the left of -5 since x is also less than -5. We then mark an open circle at -5 since x is not equal to -5.
Our number line would look like this as image attached below.
The shaded region to the left of -5 represents all values of x that are less than -5. The shaded region between -5 and -2 represents all values of x that are between -5 and -2, including -5 and -2. The open circle at -5 indicates that x cannot equal -5, but can be any other value less than -5.

The radius of a circle is 4 miles. What is the length of a 45° arc?
45°
r=4 mi
Answers
The length of a 45° arc with a radius of 4 miles is approximately 3.14 miles, calculated using the formula for arc length.
To determine the length of a 45° arc given a radius of 4 miles, we can use the formula: Arc length = (angle measure / 360°) x 2πr, where r is the radius of the circle and π is a constant equal to approximately 3.14.
Substituting the given values into the formula, we get: Arc length = (45° / 360°) x 2π(4 mi)Arc length = (1/8) x 2π(4 mi)Arc length = (1/8) x 8π Arc length = π
The length of the 45° arc is approximately 3.14 miles.
Summary: To find the length of a 45° arc of a circle, we use the formula: Arc length = (angle measure / 360°) x 2πr. Given a radius of 4 miles, we can substitute the values into the formula to get the length of the 45° arc, which is approximately 3.14 miles.
