The given problem can be solved by using Malus Law. According to Malus Law, the intensity of the light transmitted through a polarizing sheet is equal to the product of the intensity of incident light.

The square of the cosine of the angle between the polarizing axis and the transmission axis. Let the intensity of the incident light be I. Then the intensity of light transmitted through the first polarizing sheet is I. 1) Intensity of light transmitted through the second polarizing sheet is Icos²(24º)

2) Intensity of light transmitted through the third polarizing sheet is Icos²(9º)3) The percentage of light transmitted through the third polarizing sheet relative to the first one is:T = [Icos²(9º)] / [I] = cos²(9º)×100% = 92.24% ≈ 92%Thus, the percentage of light transmitted through the third polarizing sheet relative to the first one is approximately 92%.

The correct answer is 4. (3 cos θ - sin θ, 3 sin θ + θ cos θ)

To derive the parametric equations for P, we can use the concept of involutes, which is a curve that is generated by unwinding a taut string from a circle. Let O be the center of the circle, and let P be a point on the involute curve that is obtained by unwinding the thread from the spool.

We can use the angle 0 as the parameter for the parametric equations of P. Let OP = r, and let the tangent to the circle at P intersect the x-axis at point Q. Since PQ has length 30, we have:

PQ = rθ = 30

Differentiating both sides with respect to θ, we get:

r + r'θ = 0

where r' denotes the derivative of r with respect to θ. Solving for r', we get:

r' = -r/θ

Next, we can express the coordinates of P in terms of r and θ. Since P lies on the circle of radius 3 centered at O, we have:

x = 3cosθ
y = 3sinθ

To find the coordinates of Q, we note that the tangent to the circle at P is perpendicular to the radius OP. Therefore, the slope of the tangent at P is given by:

dy/dx = -cosθ/sinθ = -cotθ

Since the tangent passes through P, we can use the point-slope form of the equation of a line to get:

y - 3sinθ = -cotθ(x - 3cosθ)

Simplifying, we get:

y = 3sinθ - θcosθ

Finally, we can express the coordinates of P in terms of r and θ by eliminating r between the equations for r' and PQ, and substituting for x and y in terms of θ. This gives:

x = 3cosθ - rsinθ
y = 3sinθ + rcosθ

Substituting r' = -r/θ, we get:

x = 3cosθ - 3sinθ(θ/r)
y = 3sinθ + 3cosθ(θ/r)

Multiplying both sides of each equation by r, we get:

rx = 3r cosθ - 3θ sinθ
ry = 3r sinθ + 3θ cosθ

Therefore, the parametric equations for P in terms of θ are:

x = 3 cos θ - sin θ
y = 3 sin θ + θ cos θ

which matches option 4.

Michael needs to analyze the population data, demographics of the city, and the competition in the area to determine whether or not to open a new store.

Michael is trying to determine where to open two new store locations. He has population data to determine the amount of revenue he will receive for each location.

He is charged a $1000 fee for opening a new store at a certain location. However, he is unsure whether the population of the city would be large enough to warrant opening a new store at that location.

The first step that Michael needs to take is to analyze the population data that he has.

Based on the population data, he needs to make an informed decision about whether or not to open a new store at that location. This would require him to take into consideration the average income of the population as well as the demographics of the city.

Another important factor that Michael needs to take into consideration is the competition in the area. If there are already several stores in the area, then opening a new store might not be a good idea.

This is because the competition would be too high and he would not be able to generate enough revenue to make up for the cost of opening a new store.

However, if there are no stores in the area, then Michael might consider opening a new store. This would require him to invest a significant amount of money, but he could also generate a significant amount of revenue in return.

Additionally, he needs to take into consideration the cost of opening a new store and whether or not he can generate enough revenue to make up for that cost.

Overall, Michael needs to carefully analyze all the data that he has before making an informed decision about where to open new store locations.

In conclusion, Michael needs to analyze the population data, demographics of the city, and the competition in the area to determine whether or not to open a new store. If the population is large enough and there is no competition in the area, then he should consider opening a new store. However, if there is already a significant amount of competition in the area, then he should avoid opening a new store.

let $p$ and $q$ be the two distinct solutions to the equation$$\frac{4x-12}{x^2 2x-15}=x 2.$$if $p > q$. The value of $p - q$ is 4.

To find the value of $p - q$, we first need to solve the given equation and determine the values of $p$ and $q$.

The equation is:

$$\frac{4x-12}{x^2 - 2x - 15} = x^2.$$

Step 1: Factorize the denominator:

The denominator can be factored as $(x - 5)(x + 3)$.

Step 2: Simplify the equation:

$$\frac{4x-12}{(x - 5)(x + 3)} = x^2.$$

Step 3: Multiply both sides of the equation by $(x - 5)(x + 3)$ to eliminate the denominator:

$$(4x - 12) = x^2(x - 5)(x + 3).$$

Step 4: Expand and rearrange the equation:

$$4x - 12 = x^4 - 2x^3 - 15x^2 + 25x.$$

Step 5: Rearrange the equation and combine like terms:

$$x^4 - 2x^3 - 15x^2 + 21x - 12 = 0.$$

Step 6: Factorize the equation:

$$(x - 3)(x + 1)(x - 2)(x + 2) = 0.$$

From this, we get four possible solutions: $x = 3$, $x = -1$, $x = 2$, and $x = -2$.

However, we are interested in the two distinct solutions $p$ and $q$, where $p > q$. Therefore, the values of $p$ and $q$ are $p = 3$ and $q = -1$.

Finally, we can find the value of $p - q$:

$$p - q = 3 - (-1) = 3 + 1 = 4.$$

Hence, the value of $p - q$ is 4.

A third-degree polynomial can have either one or three real roots, depending on whether it touches the x-axis at one or three distinct points.

To explain why a third-degree polynomial must have exactly one or three real roots. A third-degree polynomial is also known as a cubic polynomial, and it can be expressed in the form:

f(x) = ax³ + bx² + cx + d

To understand the number of real roots, we need to consider the possible combinations of x-intercepts.

The x-intercepts of a polynomial are the values of x for which f(x) equals zero.

Possibility 1: No real roots (all complex):

In this case, the cubic polynomial does not intersect the x-axis at any real point. Instead, all its roots are complex numbers.

This means that the polynomial would not cross or touch the x-axis, and it would remain above or below it.

Possibility 2: One real root: A cubic polynomial can have a single real root when it touches the x-axis at one point and then turns back. This means that the polynomial intersects the x-axis at a single point, creating only one real root.

Possibility 3: Three real roots: A cubic polynomial can have three real roots when it intersects the x-axis at three distinct points.

In this case, the polynomial crosses the x-axis at three different locations, creating three real roots.

Note that these possibilities are exhaustive, meaning there are no other options for the number of real roots of a third-degree polynomial.

This is a result of the Fundamental Theorem of Algebra, which states that a polynomial of degree n will have exactly n complex roots, counting multiplicities.

The function's output values, or range, persist unchanged since it can assume any positive value for input from the vertical axis. Similarly, factorizing by adding constants does not impact the function's input values, otherwise known as the domain.

While horizontally shifting the exponentially-decreasing function, its horizontal asymptote remains unaffected; however, the positional shift depends on the magnitude and direction of said diasporic events.

The LU factorization of matrix A is A = LU, where L = [[1, 0, 0], [-2, 1, 0], [1.5, -3, 1]] and U = [[4, -8, 10], [0, 24, -27], [0, 0, -12.5]].

Let's go step by step to find the LU factorization of matrix A.

Matrix A:

A =

[4, -8, 10]

[0, 1, 0]

[0, 0, 1]

Step 2:

Perform Gaussian elimination to obtain U.

- Multiply the first row of A by (1/4) and replace the first row of A with the result.

A =

[1, -2, 2.5]

[-8, 8, -7]

[6, -7, 3]

- Subtract 8 times the first row of A from the second row of A and replace the second row of A with the result.

A =

[1, -2, 2.5]

[0, 24, -27]

[6, -7, 3]

- Subtract 6 times the first row of A from the third row of A and replace the third row of A with the result.

A =

[1, -2, 2.5]

[0, 24, -27]

[0, 5, -12.5]

Step 3:

Update the L matrix based on the operations performed during Gaussian elimination.

L =

[1, 0, 0]

[0, 1, 0]

[0, 0, 1]

Step 4:

The resulting matrix A is the upper triangular matrix U.

U =

[1, -2, 2.5]

[0, 24, -27]

[0, 5, -12.5]

Therefore, the LU factorization of matrix A is:

Using the variable "year" in the data file, we may split the data into two time periods, an early period from 1900 to 1989, and a late era from 1990 to 2010 to check if the association has altered over time.

To determine whether the average fall temperature predicts the average winter temperature in Ft. Collins, CO, we can first create a scatterplot of the response (average winter temperature) versus the predictor (average fall temperature) using the data file provided.
Upon examination of the scatterplot, we may see a positive linear relationship between the two variables, with higher fall temperatures generally corresponding to higher winter temperatures.
To formally test this relationship, we can use statistical software to fit a linear regression model of the response on the predictor. Adding the fitted line to the scatterplot allows us to see how well the line fits the data. Next, we can test the slope of the regression line to be zero against a two-sided alternative using a t-test. If the p-value is less than our chosen significance level (such as 0.05), we can reject the null hypothesis of no relationship and conclude that there is evidence of a significant linear relationship between fall and winter temperatures.
Additionally, we can calculate the coefficient of determination (R-squared) to determine the proportion of variability in winter temperatures that can be explained by fall temperatures. This tells us how well the fall temperature predicts the winter temperature. The findings of the study described above may then be repeated for each time period independently and compared.
Overall, if there is a significant relationship between fall and winter temperatures, it may be useful for predicting winter temperatures based on fall temperatures. However, it is important to consider any potential confounding variables that may also influence winter temperatures.

In a binary search of an array with 1,000 elements, if the search fails to find the item on the first attempt, there are indeed 999 elements left to search. Binary search is a divide-and-conquer algorithm that efficiently searches sorted arrays by repeatedly dividing the search space in half. If the target item is not found in the initial comparison, the search narrows down to either the lower or upper half of the remaining elements. In this case, it reduces the remaining elements from 1,000 to 999. This process continues with subsequent comparisons until the target item is found or until no more elements are left to search.

The open interval of convergence for the function f(x) = cos(x) with Taylor series centered at x = 2π is equal to (-∞, ∞).

To find the Taylor series centered at x = 2π for the function f(x) = cos(x),

Use the Maclaurin series expansion of the cosine function.

The Maclaurin series expansion for cos(x) is,

cos(x) = Σ (-1)ⁿ × (x²ⁿ) / (2n)!

Let us find the first five nonzero terms of the Taylor series expansion,

n = 0

(-1)⁰ × (x²⁰) / (20)!

= 1 / 0!

= 1

n = 1

(-1)¹ × (x²¹) / (21)!

= -x² / 2!

n = 2

(-1)² × (x²²) / (22)!

= x⁴ / 4!

n = 3

(-1)³ × (x²³) / (23)!

= -x⁶ / 6!

n = 4

(-1)⁴ × (x²⁴) / (24)!

= x⁸ / 8!

So, the first five nonzero terms of the Taylor series centered at x = 2π for f(x) = cos(x) are,

f(x) = 1 - (x - 2π)² / 2! + (x - 2π)⁴ / 4! - (x - 2π)⁶ / 6! + (x - 2π)⁸ / 8!

Now let us determine the open interval of convergence for this Taylor series.

The Maclaurin series expansion of cos(x) converges for all values of x.

Therefore, the open interval of convergence for the given Taylor series centered at x = 2π is equal to (-∞, ∞).
