Answer:

-14/3

Step-by-step explanation:

this is a geometric series with r = -7/8

The infinite sum of geometric series with |r| < 1 is

We already have r, but we need to find a1 which is the first term of the series.

To find it, only plug in 1 for n, 10(-7/8) and this = -35/4

Now plug in r and a1 in the formula above:

\(\frac{-35/4}{1+7/8}\)

after simplifying it, you will get the infinite sum = -14/3

Hermite polynomials, denoted by H(n, x), are a family of orthogonal polynomials with important applications in mathematical physics and probability theory. They are defined recursively, with base cases H(0, x) = 1 and H(1, x) = 2x. For n > 1, the recursive relation is given by H(n, x) = 2xH(n-1, x) - 2(n-1)H(n-2, x).

To implement a recursive function H that calculates the n-th Hermite polynomial at x using memoization, you can use a dictionary to store previously computed values of the polynomial. This will help in avoiding redundant computations and improve the efficiency of the algorithm.

Here's a Python implementation:

```python
def H(n, x, memo={}):
   if n == 0:
       return 1
   elif n == 1:
       return 2 * x
   else:
       if (n, x) not in memo:
           memo[(n, x)] = 2 * x * H(n - 1, x) - 2 * (n - 1) * H(n - 2, x)
       return memo[(n, x)]
```

This function takes an integer n and a double x as input and returns a double representing the value of the n-th Hermite polynomial at x. The function uses memoization to optimize performance, storing previously computed values in a dictionary called memo. This way, when encountering the same inputs again, the function can return the already computed value instead of performing the calculations anew.

The set of vectors that span s in ℝ² is {[−5, −4], [1, 0]}. In other words, the set of vectors that span s in ℝ² is {[−5, −4], [1, 0]}.

To find a set of vectors in ℝ² whose span is given by the set s, we need to express the vectors in s as linear combinations of other vectors in ℝ². The sets are defined as s = {[−5s, −4s] | s ∈ ℝ}.

To construct a set of vectors in ℝ² that spans s, we can choose two linearly independent vectors that are not scalar multiples of each other. Let's call these vectors v₁ and v₂.

Step 1: Choose a vector v₁ that satisfies the given form [−5s, −4s]. We can select v₁ = [−5, −4].

Step 2: To find v₂, we need to choose a vector that is linearly independent of v₁. One way to do this is to choose a vector that is not a scalar multiple of v₁. Let's select v₂ = [1, 0].

Step 3: Verify that the vectors v₁ and v₂ span s. To do this, we need to show that any vector in s can be expressed as a linear combination of v₁ and v₂. Let's take an arbitrary vector [−5s, −4s] from s. Using the coefficients s and 0, we can write this vector as:

[−5s, −4s] = s * [−5, −4] + 0 * [1, 0] = s * v₁ + 0 * v₂

Thus, any vector in s can be expressed as a linear combination of v₁ and v₂, which means that the span of v₁ and v₂ is s.

Therefore, the set of vectors that span s in ℝ² is {[−5, −4], [1, 0]}.

The statement "generally, parametric estimating requires less information and time than analogous estimating." is False.

Parametric estimating and analogous estimating are two different methods used to estimate the cost of a project or the value of a parameter.

Parametric estimating uses statistical data and mathematical models to make predictions about the cost or value of a project. This method requires specific data and information about the project, such as historical data, vendor quotes, and cost of similar projects.

The advantage of parametric estimating is that it can be more accurate and precise than other methods, but it can also be time-consuming to gather the necessary data and perform the calculations. Analogous estimating, uses information from similar projects to make predictions about the cost or value of a project.

This method requires less data and information than parametric estimating, but it can be less accurate and precise. Analogous estimating is often used as a quick and rough estimate, or when there is not enough data available to use parametric estimating.

Step-by-step explanation:

The order of operations requires that the multiplication be done before addition or subtraction.

  40 + 40 - 20×0 + 3 + 125

  = 40 + 40 - 0 + 3 + 125

  = 80 - 0 + 3 + 125

  = 80 + 3 + 125

  = 83 + 125

  = 208

__

The calculator shown in the attachment can be relied upon to perform calculations according to the order of operations. (It adds parentheses to show the order in which it is doing the calculation.)

Answer:

208

40 plus 40 minus 20 times 0 plus 125 in written form:

40 + 40 - 20 × 0 + 3 + 125

In order to get our answer 208, we must do it step by step:

First, we need to put 40 plus 40 into an equation:

40 + 40 = 80

Now that we have 80, we need to find 20 times 0:

20 x 0 = 0

Since 20 times 0 equals 0, we can now add 80 plus 3:

80 + 3 = 83

Now what we have left is to add 83 plus 125 which will give us our answer:

83 + 125 = 208!

The answer will be 208.

The theater has a total of 945 seats.

To determine the number of seats in the theater, we need to calculate the sum of seats in each row. The first row has 25 seats, and each subsequent row increases by one seat. Since there are 35 rows in total, we can calculate the sum of an arithmetic series to find the total number of seats.

The formula for the sum of an arithmetic series is Sn = (n/2) * (a1 + an), where n is the number of terms, a1 is the first term, and an is the last term. In this case, n = 35 (number of rows), a1 = 25 (number of seats in the first row), and an = a1 + (n - 1) = 25 + (35 - 1) = 25 + 34 = 59 (number of seats in the last row). Plugging these values into the formula, we get Sn = (35/2) * (25 + 59) = 17.5 * 84 = 1470. Therefore, the theater has a total of 945 seats.

The pressure difference between the square tube and the circular tube can be found using Bernoulli's equation, which relates the pressure of a fluid to its velocity and height. where P is the pressure of the fluid.

ΔP = 1/2 * 0.75 g/cm^3 * [(1.0 cm/s)^2 - (4v1/π)^2]

The pressure difference between the square tube and the circular tube can be found using Bernoulli's equation, which relates the pressure of a fluid to its velocity and height. Since the tube diameter changes along the length, we need to use the continuity equation to relate the velocity of the fluid in the square tube to the velocity in the circular tube.

To begin, we can use the continuity equation, which states that the mass flow rate of a fluid is constant along the length of the tube:

ρ1A1v1 = ρ2A2v2

where ρ is the density of the fluid, A is the cross-sectional area of the tube, and v is the velocity of the fluid.

Since the cross-sectional area of the square tube is A1 = (1.0 cm)^2 and the diameter of the circular tube is d = 1.0 cm, the cross-sectional area of the circular tube is A2 = π/4 * d^2 = π/4 cm^2. We are given that the mass flow rate of the gasoline is 0.60 L/s, which has a density of ρ = 0.75 g/mL = 0.75 g/cm^3.

Using the continuity equation, we can solve for the velocity of the fluid in the circular tube:

v2 = (ρ1A1v1) / (ρ2A2) = (0.75 * (1.0 cm)^2 * v1) / (π/4 cm^2)

Now that we have the velocity of the fluid in the circular tube, we can use Bernoulli's equation to relate the pressure in the square tube to the pressure in the circular tube:

P1 + 1/2 ρ1 v1^2 = P2 + 1/2 ρ2 v2^2

where P is the pressure of the fluid.

Since the tube is horizontal, the height difference between the two sections can be ignored. Thus, the pressure difference is:

ΔP = P2 - P1 = 1/2 ρ1 (v1^2 - v2^2)

Plugging in the values, we get:

ΔP = 1/2 * 0.75 g/cm^3 * [(1.0 cm/s)^2 - (4v1/π)^2]

Step-by-step explanation:

The total number of tasks Terrence completed. By substituting the value of 'x' with the number of tasks Terrence completed

The factor 'x' in the expression '90x - 20' represents the total number of tasks that Terrence completed in the game.

To understand why, let's break down the given information. It states that Shelly and Terrence completed a different number of tasks. Shelly earned 90 points on each task, so the total number of tasks she completed is not represented by 'x'.

On the other hand, Terrence's total points were 20 less than Shelly's total. This means that Terrence's total points can be calculated by subtracting 20 from Shelly's total points. Since Shelly earned 90 points on each task, her total points would be 90 multiplied by the number of tasks she completed.

So, the expression '90x - 20' represents Terrence's total points in the game, where 'x' represents the total number of tasks that Terrence completed. By substituting the value of 'x' with the number of tasks Terrence completed, we can calculate his total points.

The RTS of the isoquant is 1000K, indicating the rate at which labor can be substituted for capital while maintaining constant production. The labor to capital cost ratio is 0.5. To minimize the cost of producing q units per hour, the specific value of q is needed to find the optimal combination of K and L along the expansion path, represented by the cost function C(K, L) = 40K + 20L.

The RTS (Rate of Technical Substitution) measures the rate at which one input can be substituted for another while keeping the production level constant. To determine the RTS, we need to calculate the derivative of the production function with respect to L, holding q constant.

Given the production function q = 1000KL, we can differentiate it with respect to L:

d(q)/d(L) = 1000K

Therefore, the RTS of the isoquant for production level q is 1000K.

The ratio of labor to capital cost can be calculated by dividing the labor cost by the capital cost.

Labor cost = $20/hour

Capital cost = $40/machine/hour

Ratio of labor to capital cost = Labor cost / Capital cost

                              = $20/hour / $40/machine/hour

                              = 0.5

The ratio of labor to capital cost is 0.5.

To find the combination of K and L that minimizes the cost of producing q units per hour, we need to set up the cost function and take its derivative with respect to both K and L.

Let C(K, L) be the total cost function.

The cost of capital is $40 per machine per hour, and the cost of labor is $20 per hour. Therefore, the total cost function can be expressed as:

C(K, L) = 40K + 20L

To produce q units per hour at minimal cost, we need to find the values of K and L that minimize the total cost function while satisfying the production constraint q = 1000KL.

The expansion path of the firm represents the combinations of K and L that minimize the cost at different production levels q.
