two of the ten insist on sitting side-by-side. in how many ways can the ten be seated together in a row?
Hence, there are 725,760 ways to seat the ten people together in a row, taking into account the two individuals who insist on sitting side-by-side.
If two of the ten people insist on sitting side-by-side, we can consider them as a single entity or a pair. So, essentially, we have nine entities (including the pair) to be seated in a row.
The number of ways to arrange these nine entities in a row is 9!, which is the factorial of 9.
However, within the pair, the two individuals can be arranged in 2! = 2 ways.
Therefore, the total number of ways to seat the ten people together, considering the pair as one entity, is 9! * 2!.
Simplifying this expression:
9! * 2! = 9 * 8 * 7 * 6 * 5 * 4 * 3 * 2 * 1 * 2 = 725,760

PLEASE HELP Find x and y.
The value of x and y in the given triangle is 4 and 6 respectively.
What are similar triangles?Triangles with the same shape but different sizes are said to be similar triangles. Squares with any side length and all equilateral triangles are examples of related objects. In other words, if two triangles are similar, their corresponding sides are proportionately equal and their corresponding angles are congruent.
The two triangles are similar. Using the rule of similar triangles we have:
4/ 6 = y / y+3
4(y + 3) = 6y
4y + 12 = 6y
12 = 2y
y = 6
Similarly, using the rule of similar triangles we have:
4/6 = x/6
(4)(6) = 6x
24 = 6x
x = 4
Hence, the value of x and y in the given triangle is 4 and 6 respectively.

Sketch the region enclosed by the given curves. Decide whether to integrate with respect to x or y. Draw a typical approximating rectangle. y = x3 − 4x, y = 12x Find the area of the region
To sketch the region enclosed by the curves y = x^3 - 4x and y = 12x and determine the appropriate method of integration. By evaluating the definite integral ∫[-4 to 4] (12x - (x^3 - 4x)) dx, we can calculate the area of the region enclosed by the given curves.
The curves intersect when x^3 - 4x = 12x. Simplifying this equation, we get x^3 - 16x = 0. Factoring out x, we have x(x^2 - 16) = 0, which gives us x = 0 and x = ±4 as the intersection points.
To determine whether to integrate with respect to x or y, we can observe that the region is vertically bounded by the curves. Therefore, we'll integrate with respect to x.
To find the area of the region, we'll integrate the difference of the upper and lower curves within the given bounds, from x = -4 to x = 4.
Now, for a more detailed explanation:
First, let's analyze the curves individually. The curve y = x^3 - 4x represents a cubic function, and y = 12x represents a linear function. By plotting these curves on a graph, we can observe that they intersect at three points: (0, 0), (-4, -48), and (4, 48).
To determine the enclosed region, we need to find the x-values at which the curves intersect. Setting the two equations equal to each other, we have x^3 - 4x = 12x. Rearranging this equation, we get x^3 - 16x = 0. Factoring out x, we have x(x^2 - 16) = 0, giving us x = 0 and x = ±4 as the x-values of intersection.
Since the region is vertically bounded by the curves, we'll integrate with respect to x. To find the area, we'll integrate the difference between the upper curve (y = 12x) and the lower curve (y = x^3 - 4x) within the bounds from x = -4 to x = 4.
By evaluating the definite integral ∫[-4 to 4] (12x - (x^3 - 4x)) dx, we can calculate the area of the region enclosed by the given curves.

UT Ben deposited $10,000 into each of two savings accounts. Account I 4% Compounded Annually Account II 3% Compounded Annually Ben does not make any more deposits or withdrawals. How much more money will be in account I than account II at the end of 3 years?
After 3 years, there will be approximately $1,249 more in Account I than in Account II.
After 3 years, Account I will have grown to $11,657.84 and Account II will have grown to $10,542.31. The difference between the two accounts is $1,115.53, which is approximately $1,249 when rounded to the nearest dollar.
To calculate the balance in each account after 3 years, we can use the compound interest formula:
A = P(1 + r/n)^(nt)
Where:
A = the ending balance
P = the principal (initial deposit)
r = the annual interest rate
n = the number of times the interest is compounded per year
t = the number of years
For Account I, we have:
A = $10,000(1 + 0.04/1)^(1*3) = $11,657.84
For Account II, we have:
A = $10,000(1 + 0.03/1)^(1*3) = $10,542.31
The difference between the two accounts is:
$11,657.84 - $10,542.31 = $1,115.53

albert thought of a number, added 5, multiplied the result by 2, took away 6 and then divided by 2 to give an answer of 8. what number did albert originally think of to get to this answer?
To solve this problem, we can use the inverse operations to reverse the steps that Albert took.
First, we need to multiply the result by 2 and add 6 to get the result before the division by 2. This gives us:
8 * 2 + 6 = 16 + 6 = 22
Next, we need to divide this result by 2 and subtract 5 to get the original number that Albert thought of. This gives us:
(22 / 2) - 5 = 11 - 5 = 6
Therefore, the number that Albert originally thought of was 6.

utomobile trips there are major roads from city to city and major roads from city to city . how many different trips can be made from city to city passing through city ?
There are 8 different trips that can be made from City X to City Z, passing through City Y.
To find the number of different trips that can be made from City X to City Z, passing through City Y, we can use the multiplication principle of counting.
First, we need to choose one of the 2 major roads from City X to City Y. Then, for each of these roads, there are 4 major roads from City Y to City Z, and we need to choose one of these roads.
By the multiplication principle of counting, the total number of different trips from City X to City Z, passing through City Y, is the product of the number of choices at each stage. Thus, we get:
Number of different trips = Number of roads from City X to City Y x Number of roads from City Y to City Z
= 2 x 4
= 8

A. 1
B.0
C. 3
D. infinitely many
In space, there can be infinitely many planes that are perpendicular to a given line at a given point on that line.
The correct answer is Option D.
The key concept here is that a plane is defined by having at least three non-collinear points.
When a line is given, we can choose any two points on that line, and then construct a plane that contains both the line and those two points. By doing so, we ensure that the plane is perpendicular to the given line at the chosen point.
Since we can select an infinite number of points on the given line, we can construct an infinite number of planes that are perpendicular to the line at various points.
Thus, the correct answer is D. infinitely many planes can be perpendicular to a given line at a given point in space.

What is an exponential function?An exponential function is defined as a function whose value is a constant raised to the power of an argument is called an exponential function.
The table below shows the value in dollars of a car at the end of x years.
Number of Years, xValue, v(x) (dollars)
0 11,000
1 9,350
2 7,948
3 6,755
Let the formula for an exponential function would be as
⇒ v(x) = abˣ
Substitute the value of x = 0 and v(x) = 11,000 in the above equation,
⇒ 11,000 = ab⁰
⇒ a = 11,000
Now, substitute the value of x = 1 and v(x) = 9,350, and we get
⇒ 9,350 = ab¹
⇒ 9,350 = (11,000)b
⇒ b = 9,350/11,000
⇒ b = 0.85
Substitute the value of a = 11,000 and b = 0.85 in v(x) = abˣ,
⇒ y = 11,000 (0.85)ˣ
Thus, the exponential function is y = 11,000 (0.85)ˣ.

A game of chance is played using a six-sided die. If a 1,2 or 3 is rolled the player wins $0 if a 4 or 5 is rolled the player wins $7. If a 6 is rolled the player wins $10. If each play of the game costs 5$ what is the expected pay off?
Answer:
-2.50
Step-by-step explanation:
Using the formula for the expected value, it is found that the expected pay off is of -$1.
The expected value is given by the sum of each outcome multiplied by it's respective probability.In this problem, the outcomes and probabilities are, considering the cost of the game of $5 and that there are 6 sides:
\(\frac{3}{6}\) probability of losing $5.\(\frac{2}{6}\) probability of winning $2.\(\frac{1}{6}\) probability of winning $5.Hence:
\(E(X) = \frac{3}{6}(-5) + \frac{2}{6}(2) + \frac{1}{6}(5) = \frac{3(-5) + 2(2) + 1(5)}{6} = -\frac{6}{6} = -1\)
