(gof)(x) is a function that takes the input x and returns 3 if x = 1, 2, or 4, and 4 if x = 3.
To find the composite function (gof)(x), we first apply the function g to the input x, then apply the function f to the result.
For example, if we want to find (gof)(2), we first find g(2) = 2, then find f(2) = 4, so (gof)(2) = f(g(2)) = f(2) = 4.
So to find (gof)(x) we have to substitute the value of x in function g, then the output of function g in function f.
For the given set of functions f and g, the composite function (gof)(x) is:
(gof)(1) = f(g(1)) = f(3) = 3
(gof)(2) = f(g(2)) = f(2) = 4
(gof)(3) = f(g(3)) = f(4) = 3
(gof)(4) = f(g(4)) = f(3) = 3
So (gof)(x) is a function that takes the input x and returns 3 if x = 1, 2, or 4, and 4 if x = 3.

Can someone tell me what number on the number line is greater than -9 for an inequality?
Draw a circle over the number to begin plotting an inequality, such as x>9, on a number line (e.g., 9). If the sign also says equal to (or), then complete the circle.
What is inequality in math example?An inequality compares two values and indicates whether one is lower, higher, or just not equal to the other. It is implied by the expression a b that a and b are not equal. If a b, then a must be smaller than b. When a > b, an is greater than b.A relationship between two expressions or values that is not equal to each other is known as inequality in mathematics. So inequality emerges from an imbalance.When resolving an inequality, you can either add or subtract the same amount from each side, or multiply or divide each side by the same positive amount. The inequality sign appears if each side is multiplied or divided by a negative number.To learn more about inequality refer to:

Answer:
32.9 cm^2
Step-by-step explanation:
In the absence of a diagram, lets use the one shown in the attached worksheet. The assumption is that the "blue areas" are the four sections of the circle that extend beyond the square boundaries. The approach is to calculate areas for both the circle and the square.
Square = (11 cm)^2 = 121 cm^2
Circle = (3.14)*(14/2 cm)^2 = 153,9 cm^2
Subtract the square from the circle. That removes all the circle area, except for the four sections outside the square. The result is 32.9 cm^2

The theater sells two types of tickets: adult tickets for $11 and child tickets for $3.
Last night, the theater sold a total of 464 tickets for a total of $3520. How many adult tickets did the theater sell last night?
The adult tickets sold were 409.
What number of total adult ticket were sold?11a + 3c = 3520
Where "a" is the number of adult tickets sold and "c" is the number of child tickets sold.
We also know that the theater sold a total of 464 tickets, so we can add the following equation:
a + c = 464
We can now use the first equation to solve for one of the variables, and then substitute it into the second equation:
11a + 3c = 3520
3c = 3520 - 11a
c = (3520 - 11a)/3
We know that:
a + c = 464
We can substitute the value of c into this equation:
a + (3520 - 11a)/3 = 464
a + (3520 - 11a) = 464*3
a + 3520 - 11a = 1392
12a = 4912
a = 4912/12
a = 409
So, the theater sold 409 adult tickets last night

What is the solution to the system of equations y 2x 3. 5 and x 2y =- 14?.
The point (7, 10.5) is on the graph of both equations and satisfies the system of equations.
To find the solution to a system of equations, we need to find the values of x and y that satisfy both equations simultaneously.
The system of equations is:
y = 2x - 3.5
x - 2y = -14
We can begin by solving one of the equations for one of the variables, for example, we can solve the first equation for y:
y = 2x - 3.5
Next, we can substitute this expression for y into the second equation:
x - 2(2x - 3.5) = -14
This gives us:
x - 4x + 7 = -14
-3x = -21
x=7
Now we can substitute this value of x back into the first equation to find the corresponding value of y:
y = 2(7) - 3.5
y = 10.5
So the solution to the system of equations is x = 7, y = 10.5.

What is perimeter of triangle?
Any two-dimensional figure's perimeter is determined by the space surrounding it. By summing the lengths of the sides, we can determine the perimeter of any closed shape.
We are given a right-angled triangle with one angle 59° and the adjacent side as 145 meters.
We know that tan θ = Opposite side/Adjacent side
⇒ tan 59° = Opposite side/145
⇒ 1.66 = Opposite side/145
⇒ 241 meters(approx) = Opposite side
Now, using pythagoras theorem,
⇒Hypotenuse^2 = Base^2 + Perpendicular^2
⇒Hypotenuse^2 = 241^2 + 145^2
⇒Hypotenuse^2 = 58,081 + 21,025
⇒Hypotenuse^2 = 79,106
⇒Hypotenuse = 281 meters(approx)
Perimeter of triangle = Sum of three sides
⇒ Perimeter = 145 + 241 + 281

What is sequence?An ordered group of numbers or items is referred to as a sequence.Since each element in a series has a particular place in the sequence, the order of the elements is crucial.Sequences can either have a finite or infinite number of words, meaning they can either end or continue eternally.A formula that can be used to determine any term in a series given its location can be used to characterize sequences.a) To find a formula for the sequence, we can use a difference table.
First, let's write out the first few terms of the sequence:
3, 14, 32, 60, 98, ...
Next, we'll create a difference table:
n | Term | Difference
1 | 3 |
2 | 14 | 11
3 | 32 | 18
4 | 60 | 28
5 | 98 | 38
We see that the difference is increasing by 10 each time, so our formula can be written as:
Term = 11n + 3
To check the formula, we can plug in a few values of n and see if it matches the terms in the sequence:
n = 1, Term = 11(1) + 3 = 14
n = 2, Term = 11(2) + 3 = 32
n = 3, Term = 11(3) + 3 = 60
The formula matches the terms in the sequence, so it is correct.
b) To find the next three terms in the sequence, we can use our formula:
n = 6, Term = 11(6) + 3 = 79
n = 7, Term = 11(7) + 3 = 90
n = 8, Term = 11(8) + 3 = 101
So the next three terms in the sequence are 79, 90, and 101.

What is surface area?The surface area of an object is the total area that the object's surface occupies. It is a measure of the total area of all the exposed surfaces of an object. It is typically measured in square units, such as square meters or square inches. The surface area of an object can be calculated using various formulas, depending on the shape of the object. For example, the surface area of a cube is the area of all six faces of the cube, while the surface area of a sphere is the area of the spherical surface. The surface area is an important property of an object in fields such as engineering, physics, chemistry, and architecture.

A scale on a blueprint drawing of a house shows that 10 centimeters represents 2 meters. what number of actual meters are represented by 18 centimeters on the blueprint?
The required number of actual meters represented by 18 centimeters on the blueprint is 3.6 meters.
What is the scale factor?The scale factor is defined as the ratio of the modified change in length to the original length.
Here,
A scale on a blueprint drawing of a house shows that 10 centimeters represent 2 meters.
Scale factor,
10 centimeter: 2 meters = 1 centimeters : 0.2 meters
So,
18 centimeters = 18 × 0.2 meters = 3.6 meters.
Thus, the required number of actual meters represented by 18 centimeters on the blueprint is 3.6 meters.

5. City B has constructed their own subway system. The Green Line and the Orange Line run parallel to each other and the purple line runs perpendicularly to the Green Line and the Orange Line. The Silver Line intersects with the purple line and the green line at the same station. Angles 1 and 6 have the same measure. What is the measure of angle 9?
Answer:
135°
Step-by-step explanation:
Angles 1 and 6 have the same measure and sum to a 90 degree angle
so they are each 45°
Angles 1 and 4 are equal as well 45°
then angle 5 = 90 + 45 = 135 °
Angles 5 2 9 and 7 are all equal angle 9 = 135 °

A sixth grade class is going on a field trip. The school is providing one sack lunch for each student. Each lunch has either a ham, turkey, or bologna sandwich along with either carrots or celery.
Identify which list below shows all the possible outcomes of sack lunches, and select the outcomes from that list that represent picking a ham or turkey sandwich with carrots if there are an equal number of each type of sack lunch and students are randomly selecting their lunch. Use this information to mark the probability on the number line.
The required probability has been shown on the number as illustrated in the figure.
What is probability?Probability can be defined as the ratio of favorable outcomes to the total number of events.
Here,
There are two veggies (carrots, and celery) and three types of meat (ham, turkey, and bologna),
This results in 3*2 = 6 distinct combinations of meat and a vegetable. Here, we are limited to choosing just one of each kind. List 2 shows the 6 different combinations. List 1 is inaccurate because you can only take one vegetable at a time and not both.
List 2 alternatives that state "ham, carrots" and "turkey, carrots" should be circled. Two things have been circled. This is one of a total of six.
Probability is given as,
= 2/ 6
= 1/3

How does the sum rule work?.
The formula for the sum rule is: P(A or B) = P(A) + P(B) - P(A and B)
The sum rule, also known as the addition rule of probability, states that the probability of any two events occurring together is the sum of the probability of each event occurring individually, minus the probability of them both occurring at the same time. The formula for the sum rule is:
P(A or B) = P(A) + P(B) - P(A and B)
where A and B are two events and P(A) and P(B) are the probabilities of each event occurring individually, and P(A and B) is the probability of both events occurring at the same time.
The sum rule is used when the two events are mutually exclusive, meaning that they cannot happen at the same time. In this case, P(A and B) = 0, so the formula becomes:
P(A or B) = P(A) + P(B)
