simplify: a? should be 25x^(6)y^(6)

Step-by-step explanation

A blue token is worth 15 points and a yellow token is worth 5 points.

Two or more expressions with an Equal sign is called as Equation.

Let b  represent the point value of a blue token and

y represent the point value of a yellow token.

We can set up two equations:

4b + 7y = 95 (Jillian's score)

4b + 3y = 75 (Jacob's score)

Subtracting the second equation from the first, we get:

4b + 7y - (4b + 3y) = 95 - 75

Simplifying this, we get:

4y = 20

Dividing both sides by 4, we get:

y = 5

So a yellow token is worth 5 points.

Now we can substitute this value of "y" into one of the original equations and solve for "b".

4b + 7y = 95

4b + 7(5) = 95

4b + 35 = 95

4b = 60

b = 15

So a blue token is worth 15 points.

Therefore, a blue token is worth 15 points and a yellow token is worth 5 points.

Therefore, the average number of customers waiting in the queue (Lq) is approximately 4.17.

To predict the average number of customers waiting in the queue (Lq) in an M/D/1 queuing model, we can use Little's Law, which states that Lq = λ * Wq, where λ is the arrival rate and Wq is the average time a customer spends waiting in the queue.

In this case:

Arrival rate (λ) = 5 customers per minute

Service time (D) = 10 seconds = 10/60 = 1/6 minutes

To calculate the average time a customer spends waiting in the queue (Wq), we need to use the formula Wq = Ls / λ, where Ls is the average number of customers in the system.

In an M/D/1 queuing model, Ls can be calculated using the formula Ls = (λ²) / (μ * (μ - λ)), where μ is the service rate.

Since the service time is deterministic and given by D = 1/6 minutes, the service rate (μ) is the reciprocal of the service time: μ = 1/D = 6 customers per minute.

Now we can calculate Ls:

Ls = (λ²) / (μ * (μ - λ))

= (5²) / (6 * (6 - 5))

= 25 / 6

≈ 4.17

Finally, we can calculate Lq:

Lq = λ * Wq

= λ * (Ls / λ)

= Ls

Answer:

y = 2x + 12

Step-by-step explanation:

We need to prove that {10n : n ∈ z} = {2n : n ∈ z} ∩ {5n : n ∈ z}. To do this, we first need to prove that {10n : n ∈ z} is a subset of {2n : n ∈ z} ∩ {5n : n ∈ z} and then prove that {2n : n ∈ z} ∩ {5n : n ∈ z} is a subset of {10n : n ∈ z}.

Let us take an arbitrary element x of the set {10n : n ∈ z}. Then, x = 10n, where n ∈ z. Since 10n = 2n + 5n, x = 2n + 5n, where n ∈ z. This implies that x is a part of both the sets {2n : n ∈ z} and {5n : n ∈ z}. Hence, {10n : n ∈ z} is a subset of {2n : n ∈ z} ∩ {5n : n ∈ z}.

Let us now take an arbitrary element y of the set {2n : n ∈ z} ∩ {5n : n ∈ z}. Then, y is a part of both the sets {2n : n ∈ z} and {5n : n ∈ z}. This implies that y = 2n + 5n, where n ∈ z. Since 2n + 5n = 10n, y = 10n, where n ∈ z. Hence, {2n : n ∈ z} ∩ {5n : n ∈ z} is a subset of {10n : n ∈ z}.

Therefore, we have proven that {10n : n ∈ z} = {2n : n ∈ z} ∩ {5n : n ∈ z}.

Answer:

x = tan⁻¹(⅘)

Step-by-step explanation:

We can solve for x by using trigonometric ratios (sin, cos, and tan)

We need to apply the appropriate ratio that uses the two sides 8 and 10 from the perspective of x. See attached image for information about ratios. (Source: Math is Fun)

The tangent ratio is opposite divided by adjacent. It will relate x to the two sides. So we would write

tan(x) = ⁸⁄₁₀

Then we simplify and move the tan to the other side by multiplying both sides by the inverse of tan (since you cannot divide by tan)

tan(x) = ⅘

x = tan⁻¹(⅘)

Then we can use a calculator to evaluate x

If you want to find y, now that you have two angles of the triangle, you can find the sum of 90 + x and subtract that from 180 (since all angles of a triangle add up to 180) to find y.

The vector x = [2, -3, 1] is a basis for Row(A)⊥. This means that any vector in Row(A)⊥ can be written as a multiple of x.

To find a basis for Row(A)⊥ using the dot product, we need to find a vector that is orthogonal to all the rows of A. This means that the dot product of the vector and each row of A should be equal to 0.

Let's say the vector we are looking for is x = [x1, x2, x3]. Then we need to solve the following system of equations:

x1 * 1 + x2 * 4 + x3 * 2 = 0
x1 * 2 + x2 * 2 + x3 * 1 = 0
x1 * 3 + x2 * 1 + x3 * 1 = 0

We can write this system of equations in matrix form as:

[1 4 2] [x1] = [0]
[2 2 1] [x2] = [0]
[3 1 1] [x3] = [0]

We can use Gaussian elimination to solve this system of equations. After performing the necessary row operations, we get:

[1 0 -2] [x1] = [0]
[0 1  3] [x2] = [0]
[0 0  0] [x3] = [0]

From the last equation, we can see that x3 can be any value. Let's choose x3 = 1. Then, from the second equation, we get x2 = -3, and from the first equation, we get x1 = 2.

So, the vector x = [2, -3, 1] is a basis for Row(A)⊥. This means that any vector in Row(A)⊥ can be written as a multiple of x.

Answer: slope is 1/2

Step-by-step explanation:

Answer:

1/2

Step-by-step explanation:

Using the equation slope = y2-y1/x2-x1 we can plug in (-4,-6) as x1 and y1 and (6,-1) as x2 and y2. We than have the equation -1+6/6+4 = slope, doing the math we now have 5/10 or 1/2 which is our rate of change

The length of the hypotenuse is approximately 50.16.

As we can see in the given right angle triangle that is made in the given model,

the base is 50 and the height is 4, so  for hypotenuse,

Let's label the hypotenuse as 'c.'

We have:

\(y^2 = 50^2 + 4^2\\\\y^2 = 2500 + 16\\\\y^2 = 2516\)

To find the value of 'y,' we take the square root of both sides:

y ≈ √(2516)

y ≈ 50.16

For the slope of the given triangle,

In general slope = Δy(horizontal)/Δx(verticle)

The slope = 4/50 = 1/12.5

This slope is under state regulation since it falls between the standard ratio.

To solve this expression, we need to follow the order of operations, which is commonly remembered by the acronym PEMDAS: Parentheses, Exponents, Multiplication and Division (performed left to right), and Addition and Subtraction (performed left to right).

Using PEMDAS, we first simplify the expression inside the parentheses:

-3 + 9 = 6

The expression now becomes:

8 + 22 * 6 ÷ 3

Next, we perform the multiplication and division, starting from left to right:

The solution to the initial value problem is y(t) = -1 + e^t, y(0) = 0.

To solve the initial-value problem using the Laplace transform, we first apply the transform to both sides of the differential equation, using the linearity and derivative properties of the transform:

L{dy/dt} - L{y} = L{1}

sY(s) - y(0) - Y(s) = 1/s

sY(s) - Y(s) = 1/s

Next, we solve for Y(s):

Y(s) = 1/(s(s-1))

We can simplify this expression using partial fractions:

Y(s) = A/s + B/(s-1)

1/(s(s-1)) = A/(s) + B/(s-1)

Multiplying both sides by s(s-1), we get:

1 = As - A + Bs - B

Setting s=0, we get:

1 = -A

A = -1

Setting s=1, we get:

1 = B

B = 1

Therefore, the Laplace transform of the solution y(t) is:

Y(s) = (-1/s) + (1/(s-1))

Taking the inverse Laplace transform, we get:

y(t) = -1 + e^t

Therefore, the solution to the initial-value problem is:

y(t) = -1 + e^t, y(0) = 0

In mathematics, a triangle is a geometric shape that consists of three line segments that intersect at three endpoints. These endpoints are called vertices, and the line segments are called sides.

Triangles are one of the most basic shapes in geometry and are used in many areas of mathematics, science, engineering, and everyday life. They can be classified based on the length of their sides and the measure of their angles.

Some common types of triangles include:

Equilateral triangle: A triangle in which all three sides are equal in length.

Isosceles triangle: A triangle in which two sides are equal in length.

Scalene triangle: A triangle in which all three sides have different lengths.

Right triangle: A triangle in which one angle measures 90 degrees (a right angle).

To find the value of x, we can use the trigonometric ratios of a right-angled triangle. Let's call the base of the triangle "b".

We know that the angle between the hypotenuse and the base is 45 degrees, which means that the other acute angle is also 45 degrees. Therefore, we can use the trigonometric ratio for the sine of 45 degrees to relate the hypotenuse and the perpendicular as follows:

sin(45 degrees) = opposite/hypotenuse

where the opposite side is the perpendicular, which is given as 4√2.

sin(45 degrees) = 4√2/x

Simplifying this equation gives:

x = 4√2 / sin(45 degrees)

We know that sin(45 degrees) = 1/√2, so substituting this value into the equation above gives:

x = 4√2 / (1/√2) = 4√2 * √2 = 8

Therefore, the value of x is 8.
