As per the data, f and g are reflections of each other about the y-axis. The correct option is A.
What is graph?To graph is to create a diagram that depicts a relationship between two or more things. A graph can be made by drawing a series of bars on graph paper.
A graph (also known as an undirected graph to distinguish it from a directed graph or a simple graph to distinguish it from a multigraph) is a pair G = (V, E), where V is a set with vertices (singular: vertex) and E is a set of paired vertices with edges.
The relationship between the graphs of f(x) = -5/x and g(x) = 5/x is that they are reflections of each other about the y-axis.
To see this, note that replacing x with -x in f(x) gives f(-x) = -5/(-x) = 5/x, which is the same as g(x). Therefore, the graphs of f(x) and g(x) are symmetric with respect to the y-axis.
Thus, the correct option is A.

Find the probability of a choosing a student that is taking a foreign language, given that the student is playing a sport using the Venn Diagram below.
Answer:
7/25
Step-by-step explanation:
In simpler words, the problem wants us to find the probability of choosing a student that both play a sport and takes a foreign language.
To find this, we need to locate the intersection in the Venn diagram which is
14.
The intersection represents the number of students that both play a sport and take a foreign lang.
We have our favorable outcomes of 14.
Our total outcomes can be found by adding all the numbers like so:
23+14+10+3=50
The theoretical probability theorem is:
Number of favorable outcomes/number of total outcomes.
So our answer is 14/50, or simplified as 7/25!
Hope it helps! :))

Answer:
3.5944
Step-by-step explanation:
first the fraction is mixed and you need to change the fraction to proper or improper fraction
the denominator 4 is multiply 16
16×4=64
then the numerator 3 is add to 64
64+3=67
the fraction will be
=====67/4
the denominator is not change from the first part
》》do the same thing by the other mixed fraction
the final answer would be 3.5944
first calculate 67÷4=16.75
the second calculate 14÷3=4.66
in the second part i get 14/3 that means i change the mixed fraction to the normal fraction
calculate 16.75÷4.66=3.5944

A rotating lawn spinner sprays water on a circular area of grass, The radius of the circular area is 8ft. What measurement is closest to the area.
Answer:
Area of circle = 201.09 ft²
Step-by-step explanation:
Given the following data;
Radius, r = 8 ft
To find the area of the circular area;
Area of circle = πr²
Area of circle = 3.142 * 8²
Area of circle = 3.142 * 64
Area of circle = 201.09 ft²
Therefore, the measurement which is closest to the area is 201.09 square feet.

Step-by-step explanation:
Given
[tex](x + 9)^2 + (y - 4)^2 = 101[/tex]
Required
Which of the points does it pass through
To do this, we simply substitute the values of x and y in the above equation.
So, we have:
[tex](a)\ (1,5)[/tex]
[tex](x + 9)^2 + (y - 4)^2 = 101[/tex]
[tex](1 + 9)^2 + (5 - 4)^2 = 101[/tex]
Solve each bracket
[tex]10^2 + 1^2 = 101[/tex]
[tex]100 + 1 = 101[/tex]
[tex]101 = 101[/tex]
The above equation is true,
Hence, it passed through [tex](1,5[/tex])

A rectangle measures 2 2 /3 inches by 1 2 /9 inches. What is its area?
Answer:
88/27 or 3 7/27 in^2
Step-by-step explanation:
Multiply the length and width together:
2 2 /3 times 1 2 /9
We could either convert these measurements to improper fractions and then multiply, or we could use a calculator: 2+(2/3) ENTER x (1 + 2/9) ENTER.
Result: 3.259 in^2 (approximately) or 88/27 in^2 (exact answer)

15. Beth opens a savings account with $400. The account earns 6% interest. What will her account
value be in 5 years?
Answer:
535.29
Step-by-step explanation:
If you multiply 400 by 1.06 five times, you get 535.29.
400*1.06=424
424*1.06=449.44
449.44*1.06=476.4
476.4*1.06=504.99
504.99*1.06=535.29

Answer:
Height of triangle = 16 meter
Step-by-step explanation:
Given:
Area of given triangle = 96 squares meter
Base length of triangle = 12 meter
Find:
Height of triangle
Computation:
Area of triangle = (1/2)(b)(h)
Area of given triangle = (1/2)(Base length of triangle)(Height of triangle)
96 = (1/2)(12)(Height of triangle)
96 = (6)(Height of triangle)
Height of triangle = 96 / 6
Height of triangle = 16 meter
Two computer stores recorded the number of computers sold in a week along with the sizes of their hard drives. Number of Computers 20 GB drive 40 GB drive 80 GB drive 160 GB drive Store 1 13 11 19 9 Store 2 109 44 57 7 Use this data and a .05 significance level to test the claim that the type of hard drive and the store where the computers were bought are independent. g
Answer:
The calculated χ² = 21.455 falls in the critical region χ² ≥ 7.815 so we reject the null hypothesis that the type of hard drive and the store where the computers were bought are dependent and accept the claim the type of hard drive and the store where the computers were bought are independent.
Step-by-step explanation:
1) We set up our null and alternative hypothesis as
H0: the type of hard drive and the store where the computers were bought are dependent
against the claim
Ha: the type of hard drive and the store where the computers were bought are independent
2) the significance level alpha is set at 0.05
3) the test statistic under H0 is
χ²= ∑ (O - E)²/ E where O is the observed and E is the expected frequency
which has an approximate chi square distribution with ( 4-1) (2-1)= 3 d.f
4) Computations:
Using the calculator we summarize the results as
Under H0 , the observed frequencies are :
Observed Expected E χ²= (O-E)²/E
13 (23.58) [4.75]
11 (10.63) [0.013]
19 (14.69) [1.264]
9 (3.09) [11.282]
109 (98.42) [1.138]
44 (44.37) [0.003]
57 (61.31) [0.303]
7 (12.91) [2.703]
∑ 21.455
5) Conclusion:
The calculated χ² = 21.455 falls in the critical region χ² ≥ 7.815 so we reject the null hypothesis that the type of hard drive and the store where the computers were bought are dependent and accept the claim the type of hard drive and the store where the computers were bought are independent.
The p-value is .000085.
The result is significant at p < .05 meaning the claim is accepted.

Answer:
The value of X is 4, and the area of the triangle is [tex]60^2 units[/tex].
Step-by-step explanation:
First we need to add up all the sides. Doing so will give us the equation [tex]8x+8=40[/tex]. Subtracting 8 from both sides will give us [tex]8x=32[/tex]. Next we divide both sides by 8 in order to isolate the variable, which gives us [tex]x=4.[/tex]
This gives us 4 as our value of x.
Now we need to find the area. Substituting x into the values for base and height will give us 8+7 = 15 for our height, and 4+4=8 for our base. 15*8 is 120, and divided by two gives us 60 as out area.
Thus, x=4 and area=60.

Answer:
[tex]b = 90[/tex]
[tex]c=80[/tex]
[tex]d =100[/tex]
Step-by-step explanation:
Given
See attachment
Required
Find b, c and d
First, we solve for b using:
[tex]b + 10 + b - 10 = 180[/tex] --- base angles of a parallelogram
Collect like terms
[tex]b + b =180+10-10[/tex]
[tex]2b = 180[/tex]
Solve for b
[tex]b = 180/2[/tex]
[tex]b = 90[/tex]
Then, we have:
[tex]d =b + 10[/tex]
[tex]c = b - 10[/tex] --- opposite angles
So, we have:
[tex]d =90 + 10[/tex]
[tex]d =100[/tex]
[tex]c = 90 - 10[/tex]
[tex]c=80[/tex]

14. Which of these functions is not linear?
A) y=x^2-x
B) y=1-x
C) y=x/3
D) y=2/3x-2x
Answer:
A) y = x²- x
Step-by-step explanation:
A linear function will have y equal to x, without x being manipulated by a square root, exponent, etc.
y = x²- x has x being squared.
This will create a graph of a parabola, which is not linear.
So, since it is a quadratic instead of a line, answer choice A) y = x²- x is correct.
Please help me I'm so bad at math and doing AFDA really doesn't help..
Order the steps for this equation I guess pls help
Answer:
See the arrangement below
Step-by-step explanation:
Given the expression
2x^2+x - 9 = 4x
Step 1: Write in standard form
2x^2 + x - 9 - 4x = 0
2x^2 + x - 4x - 9 = 0
2x^2 - 3x - 9 = 0
Step 2; identify the coefficients
The standard quadratic expression is ax^2+bx+c = 0
a = 2, b = -3, c = -9
Step 3: Using the general formula to find the roots
x = -b±√b²-4ac/2a
x = -(-3)±√(-3)²-4(2)(-9)/2(2)
Step 4: simplify
x = -(-3)±√(-3)²-4(2)(-9)/2(2)
x = 3 ±√9+72/4
Step 5; Find the roots
x = 3 ±√81/4
x = 3 ±9/4
x = 3+9/4 and 3-9/4
x = 12/4 and -6/4
x = 3 and -3/2
