30 = (x) × (3x + 1)

30 = 3x² + x

3x² + x = 30

3x² + x - 30 = 0

3x² - 9x + 10x - 30 = 0

3x(x - 3) + 10(x - 3) = 0

(x - 3) (3x + 10) = 0

x = 3 ft

Thus, The value of x is 3

For Verification Only ;

30 = (x) × (3x + 1)

30 = (3) × (3*3 + 1)

30 = 3 × 10

30 = 30

There is a non zero probability of the particle in the state of finite potential .

It is an extension of the infinite potential well, in which a particle is confined to a "box", but one which has finite potential "walls". Unlike the infinite potential well, there is a probability associated with the particle being found outside the box. The quantum mechanical interpretation is unlike the classical interpretation, where if the total energy of the particle is less than the potential energy barrier of the walls it cannot be found outside the box. In the quantum interpretation, there is a non-zero probability of the particle being outside the box even when the energy of the particle is less than the potential energy barrier of the walls (cf quantum tunnelling).

The number of ways in which we can select a software engineer, an administrative assistant, and a sales representative is 48.

Since we are only choosing one option from each category, the number of alternatives for each category is equal to the number of combinations for each category .

Using the equation for each pair and then adding them up,

C (n,r) = n! / (r! (n - r)! )

Answer:

3 x y (y + x)

Step-by-step explanation:

Factor the following:

(y + x)^3 - (y^3 + x^3)

Factor the sum of two cubes. y^3 + x^3 = (y + x) (y^2 - x y + x^2):

(y + x)^3 - ((y + x) (y^2 - x y + x^2))

Factor y + x out of (y + x)^3 - (y + x) (y^2 - x y + x^2), resulting in (y + x) ((y + x)^(3 - 1) - (y^2 - x y + x^2)):

(y + x) ((y + x)^(3 - 1) - (y^2 - x y + x^2))

3 - 1 = 2:

(y + x) ((y + x)^2 - (y^2 - x y + x^2))

(y + x) (y + x) = (x) (x) + (x) (y) + (y) (x) + (y) (y) = x^2 + x y + x y + y^2 = y^2 + 2 x y + x^2:

(y + x) ((y^2 + 2 x y + x^2) - (y^2 - x y + x^2))

-(y^2 - x y + x^2) = -y^2 + x y - x^2:

(y + x) (x^2 + 2 x y + y^2 + (-y^2 + x y - x^2))

Grouping like terms, y^2 - y^2 + 2 x y + x y + x^2 - x^2 = (2 x y + x y) + (y^2 - y^2) + (x^2 - x^2):

((2 x y + x y) + (y^2 - y^2) + (x^2 - x^2)) (y + x)

There are 66 solutions to the inequality x₁ + x₂ + x₃ ≤ 11, where x₁, x₂, and x₃ are nonnegative integers.

To solve this inequality, we must find all the possible combinations of nonnegative integers x₁, x₂, and x₃ that add up to 11 or less. This can be done by breaking down the problem into a series of nested loops. The outermost loop will iterate through all possible values of x₁, while the two inner loops will iterate through all possible values of x₂ and x₃ that add up to the remaining value of 11 minus x₁. We know that the maximum value of x₁ is 11, so the outermost loop will run from 0 to 11. For each value of x₁, the inner loops will run from 0 to (11 - x₁), incrementing by 1 each time. This will ensure that all possible combinations of x₂ and x₃ that add up to 11 minus x₁ are tested. Once we have all the combinations, we can count them to get the total number of solutions. In this case, there are 66 solutions to the inequality.

f(x-3.5) means f(x) is translated 3.5 units left. 3f(x) implies f(x) is vertically stretched by a factor of 3.5.

A function is a relationship between inputs where each input is related to exactly one output. Also, translation means movement on a straight line

In the cartesian plane or graph, movement in the x-axis is either to the left (negative) or right (positive).

Thus, f(x-3.5) implies f(x) is translated 3.5 units left (i.e. -3.5)

For 3.5f(x), when you multiply f(x) by 3.5, you stretch it by 3.5. Thus, f(x) is vertically stretched by a factor of 3.5

The First Derivative Test for Local Extrema is the name of the procedure when it is used to find the values of the local maximum or minimum function.

The second derivative may be used to determine the local extrema of a function under certain conditions.

A function is said to have a local (relative) extremum at a critical point if the derivative of the function changes sign near that location. At the critical point, the function has a local (relative) maximum if the derivative switches from being positive (growing function) to negative (decreasing function). The function, however, has a local (relative) minimum at the critical point if the derivative switches from negative (decreasing function) to positive (growing function). The First Derivative Test for Local Extrema is the name of the procedure when it is used to find the values of the local maximum or minimum function.

Under certain circumstances, one can utilize the second derivative to identify the local extrema of a function. A function has a local minimum at this point if it has a critical point when f′(x) = 0 and the second derivative is positive. However, if the function contains a critical point at which the second derivative is negative and f′(x) = 0, then f has a local maximum at this location. The Second Derivative Test for Local Extrema is the name of this method.

The probability of waiting more than 0.5 minutes to get the next inquiry call is .165 seconds.

Probability is given by the number of possible outcomes ÷ number of total outcomes

Rate of phone calls = 3.6 per minute

Total number of calls between 2:00 p.m and 4:00 p.m (120 minutes) = 3.6 × 120 = 432

Number of calls in 0.5 minutes = 3.6 × 0.5 = 1.8

The probability that the number of calls in 0.5 minutes = 1.8/432 = 1/240.

In a Poisson distribution, the probability that X represents the number of successes of a random variable is given by the following formula:

[tex]P(X=x) =[/tex] e^-μ *  μ^[tex]x[/tex]

                        [tex]x[/tex]!

In which

x is the number of successes

e = 2.71828 is the Euler number

μ is the mean in the given time interval.

The probability of waiting more than 0.5 minutes to get the next inquiry call is according to a Poisson process.

Each minute has 60 seconds.

Rate of phone calls = 3.6 per minute

So a rate of 1 call every 50/3 seconds.

The probability that it takes more than 0.5 minutes for the first inquiry to arrive is approximate.

Mean of 1 call every 50/3 seconds, so for 0.5 minutes, μ = 0.5*60/50/3 = 1.8.

Dimensions of the rectangular garden are 45 yards each and area with  the calculated dimensions are 2025 square yards.

As given in the question,

Perimeter of the rectangular garden is equal to 180 yards

Let 'x' be the length and 'y' be the width of the rectangular garden

2 ( x + y ) = 180

⇒ x + y = 90

⇒ y = 90 -x

Area of the rectangular garden 'A' = xy

⇒ A = x ( 90 - x)

⇒ A = 90x - x²

To maximize the area dA/dx = 0

dA/dx = 90 - 2x

⇒ 90 - 2x = 0

⇒ 2x = 90

⇒ x = 45 yards

⇒ y = 45 yards

Area of the rectangular garden = 45 × 45

Answer:

Let's call the length of the long piece x, and the length of each shorter piece y. We can set up the following equation to represent the problem:

x + 2y = 29

Since the long piece is 1 ft longer than twice the length of each shorter piece, we can write this equation as:

x = 2y + 1

Substituting this expression for x in the first equation, we get:

2y + 1 + 2y = 29

Combining like terms on both sides, we get:

4y + 1 = 29

Subtracting 1 from both sides, we get:

4y = 28

Dividing both sides by 4, we get:

y = 7

Substituting this value for y in the expression for x, we get:

x = 2(7) + 1 = 14 + 1 = 15

Thus, the length of the long piece is 15 ft, and the length of each shorter piece is 7 ft.
