(40 points)Graph the reflection of f(x) = -3(2) across the x-axis.
Step 1: From the given function, determine the reflected
function.
g(x) = (2)*
In the equation f(x) = -3(2), reflected about x - axis is : f(x) = 3.2
According to the question, given that
equation f(x) = -3(2)
the equation reflected x - axis is f(x) = 3.2
Therefore, Reflected about the x-axis in the equation f(x) = -3(2) is f(x) = 3.2
The graph of the parent function is either "moved," "resized," or "reflected" by a function transformation. The three primary categories of function transformations are as follows:
- Translation
- Dilation
- Reflection
The only one of these transformations, dilation, alters the size of the original shape; the other two, however, just affect the shape's location.
By comparing the original and converted graphs, you can quickly determine which one has changed because you can tell by by glancing at the graph that it has moved up 2 units, left 3 units, etc. However, it can be challenging to graph the function transformation when a graph is provided. The next few steps make it much simpler to graph transformations. Here, the function y = f(x) is changed to y = a f(b (x + c)) + d.
Step 1: Write down some of the original curve's defining coordinates. Thus, we are aware of the previous x and y coordinates.
Step 2: Simply put "b (x + c) = old x-coordinate" and solve for x to determine the new x-coordinate of each location.
Step 3: Simply apply all outside operations (of brackets) on the old y-coordinate to determine the new y-coordinate of each point. To determine each new y-coordinate, find ay + d, where 'y' is the old y-coordinate.

As per the question statement, a distribution of values is normal with a mean of 198 and a standard deviation of 74.5 and we are supposed to find P(10), which is the score separating the bottom 10% from the top 90%.
Given mean (µ) = 48.5 , SD(σ) = 18.2
z = (X - μ) / σ, where X = data
X = 216.74

Since we have 3 1/2 slices of cake, and we need to distribute a half of slice by each friend, we need to divide 3 1/2 by 2, as follows:
[tex]\frac{(3\frac{1}{2})}{2}=\frac{7}{4}=1\frac{3}{4}[/tex]Therefore, since each friend gets a half slice of cake, we can affirm that each whole slice of cake can be divided into two halves.
Now, adding from half to half to obtain 3 1/2 slices of cake, give us:
1/2 + 1/2 + 1/2 + 1/2 + 1/2 + 1/2 + 1/2 = 7 slices
So, 3 1/2 slices of cake is a total of 7 halves.
Because each friend gets half of a slice of cake, we can affirm there are 7 friends.
Answer:
See below
Step-by-step explanation:
3 + one half slices each whole (3 of them ) can be cut into two halves
6 halves + 1 half = 7 halfves
if everyone gets a a half, there are 7 people
Solve the system of functions, y2 = 3x and y = 7x.
We have the following system of functions:
[tex]\begin{gathered} y^2=3x \\ y=7x \end{gathered}[/tex]The second equation gives us an expression for y. We can replace y with these expression in the first equation:
[tex]\begin{gathered} y^2=(7x)^2=3x \\ 7^2\cdot x^2=3x \\ 49x^2=3x \end{gathered}[/tex]We can substract 3x from both sides:
[tex]\begin{gathered} 49x^2-3x=3x-3x \\ 49x^2-3x=0 \end{gathered}[/tex]The x is a factor of both terms on the left. Then we can rewrite this equation:
[tex]\begin{gathered} 49x^{2}-3x=0 \\ x(49x-3)=0 \end{gathered}[/tex]So we have that the product of two terms is equal to 0. This happens when any of them is equal to 0 so we have two equations:
[tex]\begin{gathered} x=0 \\ 49x-3=0 \end{gathered}[/tex]From the first we have x=0 and we can add 3 to both sides of the second equation:
[tex]\begin{gathered} 49x-3+3=0+3 \\ 49x=3 \end{gathered}[/tex]Then we divide both sides by 49:
[tex]\begin{gathered} \frac{49x}{49}=\frac{3}{49} \\ x=\frac{3}{49} \end{gathered}[/tex]So we have the two x-values of the solutions: x=0 and x=3/49. In order to find their respective y-values we can use any of the two original functions:
[tex]\begin{gathered} y=7x\rightarrow y=7\cdot0=0\rightarrow(x,y)=(0,0) \\ y=7x\rightarrow y=7\cdot\frac{3}{49}=\frac{21}{49}\rightarrow(x,y)=(\frac{3}{49},\frac{21}{49}) \end{gathered}[/tex]AnswerWe have two solutions: (0,0) and (3/49,21/49). We can round the values of the second solution:
[tex]\begin{gathered} \frac{3}{49}\cong0.06 \\ \frac{21}{49}\cong0.43 \end{gathered}[/tex]Then the solutions are (0,0) and (0.06,0.43). Then the answer is the fourth option.

C) 2 power 2
D) 2 power 3
Answer:
[tex]2^1[/tex]
Step-by-step explanation:
Hello! So, to tackle this problem let's start off with writing out the formula as such! [tex]\frac{2^2 * 2^3}{2^4}[/tex]
To solve this, what we can do is start off by isolating [tex]\frac{2^2}{2^4}[/tex] (we can worry about [tex]2^3[/tex] later). To evaluate [tex]\frac{2^2}{2^4}[/tex], we're essentially just simplifying the fraction and reducing the exponents. In this case, we can reduce the power of 2 from both the numerator and denominator to get [tex]\frac{1}{2^2}[/tex] (this is obtained by dividing both numerator and denominator by [tex]2^2[/tex])
Once we have that, we are now essentially left with [tex]\frac{2^3}{2^2}[/tex]! From here, we can apply exponent rule, which allows us to get rid of the denominator entirely and now it becomes 2^(3-2). We can subtract the numbers to then simplify it into our answer, [tex]2^1[/tex] or in other words just 2!

The range of the function will be equal to [-1, 27].
Function may be defined as an expression in which for every input variable there is only one output variable. The input variable is the variable x and also called as independent variable and output variable is the y variable and is also called as dependent variable. Domain of a function may be defined as the set of values of all the input values. Range of a function may be defined as the set of values of all the output values. For the domain -5 ≤ x < 3 we have function x² + 2. So, if we put -5 as x, we get the value equal to 27. Also, for the domain 3 ≤ x < 7 we have the function x - 4 and if we put the value 3 as x, we get the value equal to -1. Now, the range will be equal to [-1. 27].

The meaning of the slope in this context is the change in prices with respect to the change in sizes of the houses in square feet.
Using the slope intercept equation the line won't pass through (5, 650)
How to find the slope of a line?The graph is a relationship between the cost of a home and the size of the houses in square.
Therefore, the slope can be found as follows:
The slope is the change in y with respect to the change in x.
The slope is rise over run.
Therefore,
slope of the line(m) = y₂ - y₁ / x₂ - x₁
using (1, 125)(2, 250)
m = 250 - 125 / 2 - 1
slope = 125
The slope in this context is the change in price with respect to the change in sizes of the house.
Let's check if the line will pass through (5, 650) using slope intercept equation.

The Nutty Professor sells cashews for $7.00 per pound and Brazil nuts for $4.00 per pound. How much of each type should be used to make a 33 pound mixture that sells for $5.64 per pound? pounds of cashews pounds of Brazil nuts
Let's call X the number of pounds of cashews and Y the number of pounds of Brazil nuts.
Now, we want to make 33 pounds of the mixture, so:
X + Y = 33
Adittionally, every pound mixture will be sell for $5.64 per pound. It means that:
7X + 4Y = 5.64*33
7X + 4Y = 186.12
Because every pound of cashews cost $7 and every pound of Brazil nuts cost $4
Then, we can solve for X on the first equation and replace it on the second as:
[tex]\begin{gathered} X+Y=33 \\ X=33-Y \end{gathered}[/tex][tex]\begin{gathered} 7X+4Y=186.12 \\ 7(33-Y)+4Y=186.12 \end{gathered}[/tex]So, we can solve for Y as:
