if f(x)=x-3/x, g(x)=x+3, and h(x)=2x+1, what is (g*h*f)(x).
A. 3x-6/x
B. 6x-6/x
C. 2x+4/2x+7
D. 4x-3/x
Answer:
Option B - 6x-6/x
Step-by-step explanation:
Given : If [tex]f(x)=\frac{x-3}{x}, g(x)=x+3,h(x)=2x+1[/tex].
To find : What is the value of [tex](g(h(f)))(x)[/tex]
Solution :
[tex](g(h(f)))(x)=g(h(f(x)))[/tex]
i.e, substitute the value of f(x) in h(x) and then put that h(x) in g(x).
[tex]g(h(f(x)))=g(h(\frac{x-3}{x}))[/tex]
[tex]g(h(f(x)))=g(2(\frac{x-3}{x})+1)[/tex]
[tex]g(h(f(x)))=(2(\frac{x-3}{x})+1)+3[/tex]
Solving the RHS,
[tex]=(2(\frac{x-3}{x})+1)+3[/tex]
[tex]=(\frac{2x-6}{x})+1)+3[/tex]
[tex]=(\frac{2x-6+x}{x})+3[/tex]
[tex]=\frac{3x-6}{x}+3[/tex]
[tex]=\frac{3x-6+3x}{x}[/tex]
[tex]=\frac{6x-6}{x}[/tex]
Therefore, The value of [tex](g(h(f)))(x)=\frac{6x-6}{x}[/tex]

An open rectangular box has volume 32 cm3. find the lengths of the edges giving the minimum surface area
An open rectangular box with a volume of 32 cm³ would have its minimum surface area when it takes the form of a cube. In this case, each side of the box would be approximately 3.174 cm.
Explanation:To minimize the surface area of an open rectangular box given a constant volume, the box should take the shape of a cube. This is because a cube is the three-dimensional shape that has the minimum surface area for a given volume. The volume V of the box is given as 32 cm³. Since for a cube, the volume V = a³ where a is the side length of the cube, we need to find the value of a such that the volume is equal to 32cm³.
To do this, we use the cube root function as follows: a = ∛V = ∛32 = 3.174 cm.
So, for a rectangular box with a volume of 32 cm³, the lengths of the edges that would give the minimum surface area would all be approximately 3.174 cm.

In the x -y plane, the line 3x + 2y =72 intersects the x -axis at x=b,for some number b. What is the value of b?
Since it is specifically stated that the line intersects the x-axis, then this means that y = 0. Therefore substituting y = 0 into the given equation will us the value of x.
Substituting y = 0:
3 x + 2 * 0 = 72
3 x = 72
x = 24
Therefore this means that the line intersect the x-axis at point (24, 0).

The number of bagels sold daily for two bakeries is shown in the table. Bakery A Bakery B 53 34 52 40 50 36 48 38 53 41 47 44 55 40 51 39 Based on these data, is it better to describe the centers of distribution in terms of the mean or the median? Why? Select the correct answer below.
Considering the information about the asymmetry in Bakery B's distribution, the median would be a more appropriate measure of central tendency for both Bakery A and B. It would provide a better representation of the "typical" number of cupcakes sold in each bakery, even if there might be outliers in the data.
Understanding Mean and Median:
Mean: The mean, also known as the average, is calculated by adding all the values in a dataset and dividing by the number of values. It's a good measure of central tendency when the data is symmetrical and free from outliers.Median: The median is the 'middle' value when the data is ordered from least to greatest. It's less sensitive to extreme values (outliers) compared to the mean.Why Median is More Appropriate (Considering the Information):
The information mentions that the distribution for Bakery B is not symmetric. This suggests that the data points in Bakery B might be skewed towards one side, with a few possibly higher or lower values compared to the majority.
Reasoning:
Option A (Mean): The mean is easily influenced by outliers. If Bakery B has outliers, the mean might not accurately represent the "typical" number of cupcakes sold for Bakery B.Option B (Mean for Perfect Symmetry): This option specifies the mean if the distributions are perfectly symmetrical. Since we know Bakery B's distribution isn't symmetrical, the mean wouldn't be the best choice.Option C (Median for Bakery B Asymmetry): This correctly identifies that the median is a better choice for Bakery B due to the asymmetry in its data.Option D (Median for Outliers): While outliers can be present in both Bakery A and B, the key factor is the asymmetry in Bakery B's distribution. The median is generally more resistant to the influence of outliers, making it a better choice in this case, even if outliers exist in both datasets.complete question:

If f(x) = 5x – 6, what is the equation for f–1(x)?
Answer:
5x-2+^3 hole
Step-by-step explanation:
The inverse of f(X) = (x +6 ) /5
What is inverse function?The inverse of a function f is denoted by f^-1 and it exists only when f is both one-one and onto function. Note that f^-1 is NOT the reciprocal of f. The composition of the function f and the reciprocal function f-1 gives the domain value of x.
(f o f^-1) (x) = (f^-1 o f) (x) = x
Steps To Find An Inverse FunctionThe following sequence of steps would help in conveniently finding the inverse of a function. Here we consider a function f(x) = ax + b, and aim at finding the inverse of this function through the following steps.
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/aFinally replace y = f^-1(x), and we have f^-1(x) = (x - b)/a.Given:
f(x) = 5x – 6
let y= f(x) = 5x – 6
Now, Interchange the x with y and the y with x.
x= 5y -6
x+6 = 5y
y = (x +6 ) /5
So, f^-1(x) = (x +6 ) /5
