Is F G x )) the inverse of g/f x ))?.
No, "FG)(x)" and "g/f)(x)" are not inverse of each other."FG)(x)" refers to the composition of two functions, "F" and "G", where the output of "G" is used as the input for "F".
The notation for this is represented as "F(G(x))", where "x" is the input for both functions.
The function "F" is applied to the output of the function "G", meaning that the output of the function "G" is used as the input for the function "F".
On the other hand, "g/f)(x)" is not a standard notation in mathematics. It could be interpreted as applying the function "g" to the input "x", and then applying the function "f" to the result of "g". But it could also be interpreted as applying f to the input x and then applying g to the result of f.
Inverse functions are related to the idea of reversing the effect of a function. For example, if "f" is a function that maps a set of inputs to a set of outputs, then the inverse function "f^-1" maps the set of outputs back to the original set of inputs. The notation for an inverse function is typically represented as "f^-1(x)" or "f^(-1)(x)". It's important to note that not all functions have inverses, and the inverse of a function is also a function.

What is inverse graph in graph theory?.
If the graphs of both functions are symmetric with respect to the line y = x, then we say that the two functions are inverses of each other.
The inverse function is represented by f⁻¹ with regards to the original function f and the domain of the original function becomes the range of the inverse function.
The range of the given function becomes the domain of the inverse function the injective function is the reflection of the original function with reference to the line y = x and is obtained by swapping (x, y) with the (y, x).
There are a few steps to find an Inverse Function:
For the given function f(x) = ax+b, replace f(x)=y, to obtain y = ax + b.Interchange the x with y and the y with x in the function y=ax+b to obtain x=ay+b.Here solve the expression x = ay + b for y. And we obtain y = (x - b/aFinlly replace y = f-1(x), and we have f-1(x) = (x - b)/a.To know more about inverse graph function:

What is the difference between exponential function and logarithmic function?.
Exponential functions and logarithmic functions are related but inverse of each other.
Exponential functions are used to model growth and decay, while logarithmic functions are used to model inverse growth and decay.
An exponential function is a function in the form of f(x) = b^x, where b is a positive constant called the base. The variable x is the exponent, and the value of the function is the result of raising the base to the power of x. For example, f(x) = 2^x is an exponential function. The graph of an exponential function is always increasing and never touches or crosses the x-axis, as long as b>1.
On the other hand, a logarithmic function is a function in the form of f(x) = log_b(x) or f(x) = ln(x), where b is a positive constant called the base (or e for natural logarithm) and x is the argument of the logarithm. The value of the function is the exponent to which the base must be raised to produce x. For example, f(x) = log2(x) is a logarithmic function.

C. Compute for the cross-sectional area of the parabolic tunnel. Use the Definite Integral. Show your solution.
No troll.
Answer:
A. See attached graph
B. [tex]\boxed{y = 0.12x^2+ 12}[/tex]
C. [tex]\boxed{160\;square\;feet}[/tex]
Step-by-step explanation:
Consider the figure which shows the cross-sectional view of the parabolic tunnel as viewed from the entrance
A. See attached graph
B. The parabola is drawn with the y-axis as the axis of symmetry.
The x-intercepts are at (-10, 0) and (10, 0)
The vertex is at (0, 12)
The vertex form equation for a parabola is
y = a(x - h)² + k
where (h, k) is the vertex - the (x, y) coordinates of the vertex
Here h = 0, k = 12
So the parabola equation is:
y = a(x - 0)² + 12
y = ax² + 12
To find a, plug in one of the x-intercepts, say (10, 0)
We get
0 = a(10)² + 12
0 = 100a + 12
100a = -12
a = -12/100 = -0.12
Therefore the equation of the parabola is
[tex]\boxed{y = 0.12x^2+ 12}[/tex]
C. The cross-sectional area is given by the formula:
D. To find the area of the parabola between x = -10 and x = 10 which forms the base of the parabola, you can use the formula
[tex]A = \dfrac{2}{3}bh\\\\[/tex]
where b is the base length and h is the height
Using the values for b = 20 and h = 12 we get
[tex]A = \dfrac{2}{3}\cdot 20 \cdot 12 = 160 \textrm { square feet}[/tex]
Using the definite integral, let's find the area between x = -10 and x = 10
I am not going through every step but leading you to the final answer
[tex]\int _{-10}^{10}\left(\:-0.12x^{2\:}+\:12\right)dx\\\\\\\textrm{We have}\\\\0.12\cdot \int _{-10}^{10}x^2dx=0.12\left[\frac{x^3}{3}\right]_{-10}^{10}\\\\[/tex]
[tex]=0.04\left[x^3\right]_{-10}^{10}\\\\= 80\\\\[/tex]
Therefore
[tex]-0.12\cdot \int _{-10}^{10}x^2dx = -80[/tex]
[tex]\int _{-10}^{10}12dx = \left[12x\right]_{-10}^{10} = 240[/tex]
So total area = -80 + 240 = 160 square feet

Why is triangle 180 degrees?.
A triangle is 180 degrees because the sum of the interior angles of any polygon is always equal to 180 degrees times the number of sides minus two.
A triangle is 180 degrees because the sum of the interior angles of any polygon (a closed shape with at least three straight sides) is always equal to 180 degrees times the number of sides minus two. This is known as the polygon angle sum theorem. In the case of a triangle, which has three sides, the sum of the interior angles is 180 degrees times one less than the number of sides, or 180 degrees times (3-2), which equals 180 degrees. Additionally, since a triangle is a three-sided polygon, and each angle in a triangle is connected by three straight lines, the sum of the three angles in a triangle must always add up to 180 degrees.

Challenge The price of Stock A at 9 A.M. was $13.45. Since then, the price has been increasing at the rate of $0.08 each hour. At noon the price of Stock B was $14.20. It begins to decrease at the rate
of $0.14 each hour. If the two rates continue, in how many hours will the prices of the two stocks be the same?
In about hours, the prices of the two stocks will be the same.
(Round to the nearest tenth as needed.)
Answer:
Approximately 2.3 hours after 12 noon
Step-by-step explanation:
We are given
Stock A price at 9AM = $13.45
It increases by $0.08 per hour
Stock B at noon = $14.20
It decreases by $0.14 each hour
We have to find when the two prices will be the same.
Since the base time references are different - 9am for A and noon for B, we have to establish the same time reference
Let's do this by finding the price of stock A at noon, then we have the same time base reference of noon
9am - noon = 3 hours
In 3 hours stock A would have risen by 0.08 x 3 = $0.24
Price of stock A at noon is 13.45 + 0.24 = $13.69
Thereafter stock A continues to increase by the same rate of $0.08 per hour
The equation to model stock A price starting at noon is
13.69 + 0.08x where x is the number of hours elapsed after 12 noon
Stock B price is $14.20 at 12 noon and decreases by $0.14 per hour
Equation to model stock B price after 12 noon is
14.20 - 0.14x where x is the elapsed time after 12 noon
For both prices to be the same after the same x hours, we have
13.69 + 0.08x = 14.20 - 0.14x
Solving for x will tell us how many hours it will take for both stock prices to be the same
Solving
13.69 + 0.08x = 14.20 - 0.14x
So the two stock prices will be the same 2.3 hours after 12 noon or about 2 hours and 18 minutes after 12 noon or roughly around 2:18pm
I got 18 minutes by multiplying 0.3 x 60 = 18

beginning of the year. Write an equation for each situation, in terms of t, and
determine the number of weeks after the beginning of the year until Salma and Henry
have the same amount of money saved. PLEASE ANSWERR
Answer:
20 weeks
Step-by-step explanation:
Salma's savings can be represented by the equation S = 35 + 8t, where t is the number of weeks after the beginning of the year.
Henry's savings can be represented by the equation H = 95 + 5t
To determine the number of weeks after the beginning of the year until Salma and Henry have the same amount of money saved, we need to set the two equations equal to each other and solve for t:
35 + 8t = 95 + 5t
3t = 60
t = 20
So it would take Salma and Henry 20 weeks after the beginning of the year to have the same amount of money saved.
Why can't the denominator of a fraction be negative?
When you divide a fraction by a negative number, it doesn't matter what happens to the denominator because the entire result, or quotient, is the reverse of whatever the original fraction was.
What is the denominator?In mathematics, a denominator is the lowest number in a fraction that indicates how many equal parts are divided into a whole.
It is a fraction's divisor. In this case, the denominator is 4, thus there are four components overall.
The top number in a fraction is referred to as the numerator, while the bottom number is referred to as the denominator.
4/5, for instance, is a fraction.
What happens to the denominator of a fraction when you divide it by a negative number is unimportant because the entire result, or quotient, is the opposite of whatever the original fraction was.

Let's start by finding the smallest 6-digit number with five different digits.
We know that 0 is the smallest digit that can not be used in the highest place value, so we will consider the next smallest digit, 1; therefore, it can be used in the highest place value.
Thus, we can create the required 6-digit smallest number with 0 and 1.
Hence, the smallest 6-digit number is 100234.
Now, we will discover the largest 5-digit number.
As we know, the largest digit is 9, which can be used anywhere. So, we will form the largest 5-digit number with the digit 9.
Thus, the largest 5-digit number is 99876.
Now, calculate the difference between these two numbers.
So, we can determine the difference between the smallest 6-digit number and the largest 5-digit number by subtracting the smallest from the largest.
Thus, we get,
⇒100234 - 99876
⇒358
Hence, 358 is the difference between the smallest 6-digit with five different digits and the largest 5-digit number with four different digits.

Lemon travels 35 miles per hour. How long does it take her to travel 315 miles? Provide and answer, in hours accurate to the nearest tenth.
Answer: 9 hours
Step-by-step explanation: To find the answer, I did:
315 / 35 = ? * 1
=9 * 1
= 9
I divided the 315 by the 35 because that would give us how many hours she drives. (at a constant rate) So, given that, I got 9. I hope this helped!
Katie rolled a fair number cube, with face numbered 1 to 6, 200 time. She rolled the number 5, five time. What i the experimental probability of landing on landing on 5? How doe it compare to the theoretical probability of landing on 5?
The theoretical likelihood of receiving a 2 is 1/6, but the actual likelihood is 1/3.
They are divided by one-half.
The potential likelihood
The theoretical likelihood of receiving a 2 is 1/6, which is the ratio of the number of fortunate events to all possible outcomes.
The experimental likelihood
The experimental probability of an event occurring is the proportion of total times the experiment was conducted that an event occurred during the experiment.
in this case, is 6/12 or 1/2.
1/2 - 1/6 = 3/6 - 1/6 = 2/6 = 1/3

A. 14.4 feet
B. 4 feet
C. 9 feet
D. 3.8 feet
The required radius of the cylinder that can be covered by the paint is 3.8 feet. Option D is correct.
How to find the radius?Franco has enough paint to cover an area of approximately 226 square feet. He needs to paint a cylinder that is 5 feet, and the maximum possible radius of the cylinder that can be covered by the paint is to determined.
Recall that a cylinder is defined as a 3D solid that keeps two identical bases joined by a curved surface, at a certain distance.
Here,
Franco has enough paint to cover an area of approximately 226 square feet.
Area of the cylinder = 226
πr²h = 226
h = 5 feet and π = 3.14
3.14 * 5 * r² = 226
r² = 226/15.70
r = √14.70
r = 3.80
Thus, the required radius of the cylinder that can be covered by the paint is 3.8 feet. Option A is correct.
