How do u write a function for the reflection across the y axis
The function for the reflection across the y-axis can be written as: f(x,y)=(−x,y)
To reflect a point across the y-axis, we multiply its x-coordinate by -1. This means that if a point has coordinates (x,y), its reflection across the y-axis will have coordinates (−x,y).
We can use this to define a function for the reflection across the y-axis. Let f(x,y) be the function that reflects a point across the y-axis. Then, for any point (x,y), we have:
f(x,y)=(−x,y)
In other words, f(x,y) takes a point (x,y) and returns its reflection across the y-axis.
We can also write this function in terms of components. Let x and y be the coordinates of a point. Then, the reflection of this point across the y-axis has coordinates (−x,y). Therefore, the function for the reflection across the y-axis can be written as:
f(x,y)=(−x,y)
This function takes the coordinates of a point as input and returns the coordinates of its reflection across the y-axis as output.
What is the slope of the line that contains the points (4, 3) and (2, 7)?
Answer:
-2
Step-by-step explanation:
given 2 points on a line (x1, yx) and (x2,y2)
the formula for slope, m = (y2-y1) / (x2-x1)
in this case,
x1 = 4, y1 = 3, x2 = 2, y2 = 7
Hence,
m = (7-3) / (2-4) = 4 / -2 = -2
The slope of the line that contains the points (4, 3) and (2, 7) is -2.
How to estimate the slope of the line?To estimate the slope of the line that has the points (4,3) and (2,7)
Slope formula = y₂ - y₁ / x₂ - x₁
From the question, the points given are; (4,3) and (2,7)
So, x₁ = 4, y₁ = 3, x₂ = 2 and y₂ = 7
Slope of the line = 7 - 3 / 2- 4
= -2
The slope of the line is -2.
therefore, the correct answer is option D. -2.

Answer:
case a) [tex]x^{2}=3y[/tex] ----> open up
case b) [tex]x^{2}=-10y[/tex] ----> open down
case c) [tex]y^{2}=-2x[/tex] ----> open left
case d) [tex]y^{2}=6x[/tex] ----> open right
Step-by-step explanation:
we know that
1) The general equation of a vertical parabola is equal to
[tex]y=a(x-h)^{2}+k[/tex]
where
a is a coefficient
(h,k) is the vertex
If a>0 ----> the parabola open upward and the vertex is a minimum
If a<0 ----> the parabola open downward and the vertex is a maximum
2) The general equation of a horizontal parabola is equal to
[tex]x=a(y-k)^{2}+h[/tex]
where
a is a coefficient
(h,k) is the vertex
If a>0 ----> the parabola open to the right
If a<0 ----> the parabola open to the left
Verify each case
case a) we have
[tex]x^{2}=3y[/tex]
so
[tex]y=(1/3)x^{2}[/tex]
[tex]a=(1/3)[/tex]
so
[tex]a>0[/tex]
therefore
The parabola open up
case b) we have
[tex]x^{2}=-10y[/tex]
so
[tex]y=-(1/10)x^{2}[/tex]
[tex]a=-(1/10)[/tex]
[tex]a<0[/tex]
therefore
The parabola open down
case c) we have
[tex]y^{2}=-2x[/tex]
so
[tex]x=-(1/2)y^{2}[/tex]
[tex]a=-(1/2)[/tex]
[tex]a<0[/tex]
therefore
The parabola open to the left
case d) we have
[tex]y^{2}=6x[/tex]
so
[tex]x=(1/6)y^{2}[/tex]
[tex]a=(1/6)[/tex]
[tex]a>0[/tex]
therefore

An exam was given to a group of freshman and sophomore students. The results are below: Freshman: 106 got A’s, 130 got B’s, and 149 got C’s. Sophomore: 192 got A’s, 118 got B’s, and 168 got C’s. If one student is chosen at random from those who took the exam, find the probability that: a) the student was a sophomore. round to 4 decimal places as needed.
Answer:
106 + 130 + 149 + 192 + 118 + 168 =
863 total students
192 + 118 + 168 = 478 sophomores
P(sophomore) = 478/863
= about .5539
The probability that a randomly chosen student was a sophomore is approximately [tex]\(0.5538\)[/tex] .
To find the probability that a randomly chosen student was a sophomore, we need to calculate the total number of students and the total number of sophomores. Then we use the probability formula:
[tex]\[ P(\text{Sophomore}) = \frac{\text{Number of Sophomores}}{\text{Total Number of Students}} \][/tex]
Step-by-Step Calculation
1. Number of Freshmen:
- A's: 106
- B's: 130
- C's: 149
Total Freshmen:
[tex]\[ 106 + 130 + 149 = 385 \][/tex]
2. Number of Sophomores:
- A's: 192
- B's: 118
- C's: 168
Total Sophomores:
[tex]\[ 192 + 118 + 168 = 478 \][/tex]
3. Total Number of Students:
[tex]\[ 385 + 478 = 863 \][/tex]
4. Probability Calculation:
[tex]\[ P(\text{Sophomore}) = \frac{478}{863} \][/tex]
Let's calculate this probability and round to 4 decimal places:
[tex]\[ P(\text{Sophomore}) \approx \frac{478}{863} \approx 0.5538 \][/tex]
Henry recorded the number of miles he biked each day for a week. His miles were 25, 40,35, 25, 40, 60, and 75,
Enter the data into the statistics calculator,
What is the standard deviation of the miles Henry biked to the nearest tenth?
Answer:
SD = 17.1 miles
Step-by-step explanation:
In order to find the SD we have to calculate mean first
So,
[tex]Mean = \frac{sum}{no.\ of\ items} \\=\frac{25+40+35+25+40+60+75}{7}\\ =\frac{300}{7}\\ =42.86[/tex]
Now mean will be subtracted from each value and the answers will be squared
So,
X X-mean (X-mean)^2
25 -17.86 318.9796

40 -2.86 8.1796
60 17.14 293.7796
75 32.14 1032.9796
So,
Sum of squares = 2042.8572
As SD is the square root of variance
so,
Variance = Sum of squares / number of data values
=2042.8572/7
=291.84
Hence,

Which of the following represents the solution of 3/2 = 3x/2x minus 6/5X
a) x=1/5
b)x=5/9
c)all real numbers
d)no solution
(im pretty bad at math)
Answer: d) No solution.
Step-by-step explanation:
Given the equation:
[tex]\frac{3}{2}=\frac{3x}{2x}-\frac{6}{5x}[/tex]
The denominator of the fractions cannot be zero, then, the Domain is:
[tex]x\neq 0[/tex]
Simplify:
[tex]\frac{3}{2}=\frac{3}{2}-\frac{6}{5x}[/tex]
Subtract [tex]\frac{3}{2}[/tex] from both sides of the equation. Then you get:
[tex]\frac{3}{2}-(\frac{3}{2})=\frac{3}{2}-\frac{6}{5x}-(\frac{3}{2})\\\\0=-\frac{6}{5x}[/tex]
Multiply both sides of the equation by [tex]5x[/tex] ([tex]5x \neq 0[/tex]), then:
[tex](5x)(0)=(-\frac{6}{5x})(5x)[/tex]
Since the multiplication of [tex]5x[/tex] by zero is zero, you get:
[tex]0=-6[/tex] (This is FALSE)
Therefore, since there is no value for the variable that makes the equation true, the equation has NO SOLUTION.

Which functions are even? Check all of the boxes that apply.
f(x) = x4 – x?
f(x) = x2 – 3x + 2
f(x) = (x - 2)
f(x) = x
DONE
Answer:
None of the functions are even.
Step-by-step explanation:
Even FunctionsAn even function is a function that appears unchanged if reflected upon the y axis.
An example of such function is the function y = x^2, which would not appear to have been changed if we were to reflect it across the y axis.
The core property of even functions is that for any even function f(x), the following condition is always true:
[tex]f(x) = f(-x)[/tex]
Thus, if we'd like to identify whether or not a function is even, we can check if that condition is true. If it is, the function is even.
Breaking Down The OptionsNow that we know how to identify even functions, we can apply this method to all of the given options and identify whether or not they're even.
[tex]$\begin{enum}\begin{align}\text{1) }&f(x) = x^4-x\\&f(-x)= (-x)^4-(-x)=x^4+x\\\\&\implies f(x)\neq f(-x) \textbf{ Not even!}\\\\\text{2) }&f(x)=x^2-3x+2\\&f(-x)=(-x)^2-3(-x)+2=x^2+3x+2\\\\&\implies f(x)\neq f(-x) \textbf{ Not even!}\\\\\text{3) }&f(x)=x - 2\\&f(-x)=-x-2=-(x-2)\\\\&\implies f(x)\neq f(-x) \textbf{ Not even!}\\\\\text{4) }&f(x)=x\\&f(-x)=-x\\\\&\implies f(x)\neq f(-x) \textbf{ Not even!}\end{align}\end{enum}$[/tex]
None of the functions are even.
Derive the equation of the parabola with a focus at (-5,5) and a directix of y = -1
Answer:
D
Step-by-step explanation:
From any point (x, y) on the parabola the focus and directrix are equidistant
Using the distance formula
[tex]\sqrt{(x+5)^2+(y-5)^2}[/tex] = | y + 1 |
Squaring both sides
(x + 5)² + (y - 5)² = (y + 1)^2 , that is
(y + 1)² = (x + 5)² + (y - 5)² ← subtract (y - 5)² from both sides
(y + 1)² - (y - 5)² = (x + 5)² ← expand left side and simplify
y² + 2y + 1 - y² + 10y - 25 = (x + 5)²
12y - 24 = (x + 5)² ← factor left side
12(y - 2) = (x + 5)² ← divide both sides by 12
y - 2 = [tex]\frac{1}{12}[/tex] (x + 5)² ← add 2 to both sides
y = [tex]\frac{1}{12}[/tex] (x + 5)² + 2
or
f(x) = [tex]\frac{1}{12}[/tex] (x + 5)² + 2 → D

A randomly generated list of number from 0 to 8 is being used to simulate an event, with numbers 0, 1, and 2 representing a success. What is the estimated probability of a success
A. 25%
B. 20%
C. 33%
D. 30%
Answer:
C) 33%
Step-by-step explanation:
To solve for the percentage of success, we first need to find out how many numbers we are working with. In this case, there are 9 numbers (0,1,2,3,4,5,6,7,8).
Since there are 3 "successful" numbers, (0,1,2), we can write the probability as a fraction
3/9 (represents number of successes over number of possible outcomes)
This simplifies to be 33%
Answer:
C
Step-by-step explanation:
Since you include zero as a number, then it would be 9 numbers in all. 3 if the nine numbers are success, so it would be 3/9. 3/9 as a percent would be around 33 percent.

You are going to go to the grocery store. You have $25 to spend. There are several items on your list that you must purchase and some are “for fun” items that you can purchase if you have enough money.
Your list: 2 gallons of milk for $3.50 each; 2 loaves of bread for $2.75 each; 1 pot roast for $10.45 each.
You want to also purchase some candy bars. The candy is on sale for 43 cents each. Ignore sales tax and answer the following questions.
a. Write an equation representing your shopping experience and use x for the number of candy bars.
b. Solve the equation to determine how many candy bars can you purchase?
c. How much change would you have left?
Answer:
Part a) [tex]22.95+0.43x \leq 25[/tex]
Part b) The maximum number of candy bars that you can purchase is 4
Part c) The change would be [tex]\$0.33[/tex]
Step-by-step explanation:
Part a) Write an equation representing your shopping experience and use x for the number of candy bars
Let
x -----> the number of candy bars
we know that
The inequality that represent this problem is equal to
[tex]2(3.50)+2(2.75)+10.45+0.43x \leq 25[/tex]
[tex]22.95+0.43x \leq 25[/tex]
Part b) Solve the equation to determine how many candy bars can you purchase?
[tex]22.95+0.43x \leq 25[/tex]
Solve for x
Subtract 22.95 both sides
[tex]0.43x \leq 25-22.95[/tex]
[tex]0.43x \leq 2.05[/tex]
Divide by 0.43 both sides
[tex]x \leq 2.05/0.43[/tex]
[tex]x \leq 4.8[/tex]
The maximum number of candy bars that you can purchase is 4
Part c) How much change would you have left?
If you purchase 4 candy bars
then
[tex]22.95+0.43(4)=\$24.67[/tex]
therefore
[tex]\$25-\$24.67=\$0.33[/tex]
The equation representing the shopping experience is 3.50*2 + 2.75*2 + 10.45 + 0.43x = 25. The maximum number of candy bars you can purchase is 4. You would have $1.05 in change left.
Explanation:a. The equation representing your shopping experience can be written as: 3.50*2 + 2.75*2 + 10.45 + 0.43x = 25, where x represents the number of candy bars.
b. To determine how many candy bars you can purchase, we need to solve the equation for x. First, combine like terms: 7 + 5.50 + 10.45 + 0.43x = 25. Subtracting 22.95 from both sides gives 0.43x = 2.05. Dividing both sides by 0.43 gives x ≈ 4.77. Since you can't purchase a fraction of a candy bar, the maximum number of candy bars you can buy is 4.
c. To find out how much change you would have left, subtract the total cost of items from your budget. The cost of items is 3.50*2 + 2.75*2 + 10.45 = 23.95. Subtracting this from your budget of $25 gives 25 - 23.95 = $1.05 in change.

Answer:
4
Step-by-step explanation:
16 cups = 4 quarts
Please mark brainliest and have a great day!
Answer:
4 quarts
Step-by-step explanation:
We are given that a container of fruit punch serves 16 cups and we are to find the number of quarts that are in a container.
For this, we will use the ratio method.
We know that, 1 cup = 0.25 quarts, so:
[tex] \frac { 1 cup } { 1 6 cups } = \frac { 0 . 2 5 quarts } { x } [/tex]
[tex] x = 1 6 \times 0 . 2 5 [/tex]
[tex]x=4 quarts[/tex]
Therefore, there are 4 quarts of fruit punch in the container.
