This is the graph of f(x) = x+A/x+B. The grid lines in the graph are one unit apart. What is the value of A/B
Answers
The value of A/B is given as follows:
A/B = -2.
What are the asymptotes of a function f(x)?The vertical asymptotes are the values of x which are outside the domain, which in a fraction are the zeroes of the denominator.The horizontal asymptote is the value of f(x) as x goes to infinity, as long as this value is different of infinity.From the graph, the function has a vertical asymptote at x = 1, hence the value of B is given as follows:
B = -1 -> as x + B = 0 -> x = -B = -1.
When x = 0, y = -2, hence the value of A is obtained as follows:
A/-1 = -2
A = 2.
Then the division is given as follows:
A/B = 2/-1 = -2.

Answers
Here are the pairs matched with their products:
- (-5)(4.2) matches with -21
- (-7)(-3) matches with 21
- (2.5)(-9) matches with -22.5
Pairs (4) and (5) do not have corresponding products in the given options.
(-5)(4.2) = -21
(-7)(-3) = 21
(4)(5) = 20
(2.5)(-9) = -22.5
So, the pairs of numbers and their products are as follows:
(-5)(4.2) = -21 matches with -21.
(-7)(-3) = 21 matches with 21.
(4)(5) = 20 matches with 20.
(2.5)(-9) = -22.5 matches with -22.5.

Keira said that if 6 tickets are sold, there should be 2 tickets left. Is Keira correct?
Answers
According to Keira, if 6 tickets are sold, there should be 2 tickets left. However, we don't have any information about the initial number of tickets available.
If the total number of tickets initially was 8, and 6 tickets were sold, then there would indeed be 2 tickets left, supporting Keira's statement.
However, if the total number of tickets initially was less than 8, or if the statement doesn't specify the initial number of tickets, we cannot determine if Keira's statement is correct.
Therefore, without additional information, we cannot determine the accuracy of Keira's statement.

A corner shelf is in the shape of a triangle. One side measures \(2x^2 + 2x -1\) while another side measures \(5x + x^2 - 3\)
What is the total of two sides? Show all work.
If the perimeter measures\(3x^3 - x^2 - 8x +1\) what is the length of the missing side? Show all work.
If we know that \(x =2\) then what are the lengths of the three sides of the triangle? Show all work.
Is it possible to have these side lengths? Why or why not?
Answers
1.The total of two sides is: $6 + 8 = 14$.
2.The missing side has a length of 4.
3.All three inequalities are true, so these side lengths do form a valid triangle.
4. It is not possible to have side lengths.
1. To find the total of two sides of the triangle shelf, we simply add the two given side measurements together.
2. $Perimeter = a + b + c$ where a, b, and c are the lengths of the three sides of the triangle. We are given that the perimeter measures 18, and we know that 6 and 8 are two of the sides, so we can substitute these values into the formula to solve for c:
$18 = 6 + 8 + c$
$18 - 14 = c$
$4 = c$
3. If we know that $a$ = 3, $b$ = 5, and $c$ = 8, we can check if these side lengths form a valid triangle by using the triangle inequality theorem, Therefore, we need to check if:
$a + b > c$
$b + c > a$
$a + c > b$
Substituting in the given values, we get:
$3 + 5 > 8$ (True)
$5 + 8 > 3$ (True)
$3 + 8 > 5$ (True)
4. of $a$ = 2, $b$ = 4, and $c$ = 7 for a triangle. The triangle inequality theorem states that the sum of any two sides of a triangle must be greater than the third side. If we apply this to the given values, we get:
$a + b > c$
$2 + 4 > 7$ (False)
For such more questions on inequalities
https://brainly.com/question/25275758
#SPJ8
The total of two sides is a + b.
If the perimeter is P, then we have a + b + c = P, where c is the missing side. Solving for c, we get c = P - a - b.
If we know that a + b = c, then we have a + b = a + b + c - b - a, which simplifies to 0 = c. This means that the triangle has one side of length 0, which is impossible.
Therefore, it is not possible to have these side lengths.
Without knowing the values of a and b, we cannot find the total of two sides, the length of the missing side, or the lengths of the three sides of the triangle.

Part B: Calculate the measures of variability. Show all work. (1 point)
Part C: If you are interested in a smaller class size, which school is a better choice for you? Explain your reasoning. (1 point)
Answers
For Mountain View School:
Data: 0, 0, 0, 0, 1, 2, 3, 4, 4, 5, 5, 5, 5, 6, 7, 8, 8, 8, 9
Mean: (0 + 0 + 0 + 0 + 1 + 2 + 3 + 4 + 4 + 5 + 5 + 5 + 5 + 6 + 7 + 8 + 8 + 8 + 9) / 19
= 100 / 19
≈ 5.26
To find the median, we need to arrange the data in ascending order: 0, 0, 0, 0, 1, 2, 3, 4, 4, 5, 5, 5, 5, 6, 7, 8, 8, 8, 9.
The median is the middle value, which is the 10th value in this case.
Median: 5
For Seaside School:
Data: 0, 0, 0, 1, 1, 2, 2, 4, 5, 5, 5, 5, 6, 7, 7, 8, 8, 8, 9
Mean: (0 + 0 + 0 + 1 + 1 + 2 + 2 + 4 + 5 + 5 + 5 + 5 + 6 + 7 + 7 + 8 + 8 + 8 + 9) / 19
= 80 / 19
≈ 4.21
To find the median, we need to arrange the data in ascending order: 0, 0, 0, 1, 1, 2, 2, 4, 5, 5, 5, 5, 6, 7, 7, 8, 8, 8, 9.
The median is the middle value, which is the 10th value in this case.
Median: 5
Now let's calculate the measures of variability, specifically the range and interquartile range (IQR).
Range: The range is the difference between the largest and smallest values in the dataset.
For Mountain View School:
Range: 9 - 0 = 9
For Seaside School:
Range: 9 - 0 = 9
Interquartile Range (IQR): The IQR is the difference between the third quartile (Q3) and the first quartile (Q1) and measures the spread of the middle 50% of the data.
For Mountain View School:
Q1 = 3
Q3 = 7
IQR = Q3 - Q1 = 7 - 3 = 4
For Seaside School:
Q1 = 2
Q3 = 7
IQR = Q3 - Q1 = 7 - 2 = 5
To determine which school is a better choice for a smaller class size, we can consider both the mean and the median.
Both the mean and median for Mountain View School are higher than those for Seaside School. This suggests that, on average, the class sizes at Mountain View School are larger than those at Seaside School. Therefore, if you are interested in a smaller class size, Seaside School would be a better choice
For Mountain View School:
- Median: The median class size is the middle value, which is 25.
- Mean: The mean class size is the sum of all the class sizes divided by the total number of classes, which is (29 + 28 + 28 + 27 + 25 + 24 + 24 + 23 + 21 + 20 + 19 + 18 + 15 + 13 + 10) / 15 = 21.27.
For Seaside School:
- Median: The median class size is the middle value, which is 20.
- Mean: The mean class size is the sum of all the class sizes divided by the total number of classes, which is (25 + 25 + 27 + 27 + 28 + 28 + 28 + 30 + 31 + 35 + 36 + 38 + 40 + 43 + 45) / 15 = 31.13.
Part B:
For Mountain View School:
- Range: The range is the difference between the largest and smallest values, which is 29 - 10 = 19.
- Interquartile Range (IQR): The IQR is the difference between the third quartile (Q3) and the first quartile (Q1). From the stem-and-leaf plot, we can see that Q1 is 20 and Q3 is 28. Therefore, the IQR is 28 - 20 = 8.
For Seaside School:
- Range: The range is the difference between the largest and smallest values, which is 45 - 25 = 20.
- Interquartile Range (IQR): The IQR is the difference between the third quartile (Q3) and the first quartile (Q1). From the stem-and-leaf plot, we can see that Q1 is 27 and Q3 is 38. Therefore, the IQR is 38 - 27 = 11.
Part C:
If you are interested in a smaller class size, Mountain View School is a better choice for you because it has a lower mean and median class size than Seaside School.

so the triangular shape would be
.5(6) * 8 = 24
.5(14) * 8 = 56
14 * 12 = 168
then you add 168 + 56 + 56 + 24 + 24 = 328
the surface area of the triangular shape is 328
the surface area of the rectangular prism
29 * 21 = 609
35 * 29 = 1015
21 * 35 = 735
735 + 735 + 1015 + 1015 + 609 + 609 = 3808
therefor the rectangular prism has a greatest surface area than the triangular shape because 3808 is greater than 328
