At the movie theatre, child admission is $6.10 and adult admission is $9.40. On Monday, twice as many adult tickets as child tickets were sold, for a total sale of $498.00. How many child tickets were sold that day?

Hence, g(n) = 2n is a lower bound for 3n - 4 as g(n) >= 3n - 4 for all n >= 1 and c = 2 is the largest constant possible.

To sum up, the lower bound of 3n - 4 is - Ω(n) and g(n) = 2n is a function that grows at least as fast as f(n) for all n >= 1.

To find a lower bound for 3n - 4, we need to find a function g(n) that is asymptotically larger than 3n - 4.

Since we are looking for a lower bound, we use the big omega notation, which is denoted by Ω.Lower bound means the function we get has to be greater than or equal to f(n) i.e 3n - 4.

The big omega notation tells us the lower bound of a function. Here g(n) is said to be a lower bound for f(n)

if there exist positive constants c and n0 such that g(n) is less than or equal to f(n) for all n greater than or equal to n0. In other words, g(n) is a function that grows at least as fast as f(n).

The lower bound for 3n - 4 is - Ω(n).

To prove this, we need to find the values of c and n0, such that g(n) >= 3n - 4 for all n >= n0.g(n) = cn, let's say n0 = 1 and c = 2. then:

g(n) = cn >= 2n >= 3n - 4 for all n >= n0

The second integral can be evaluated as follows:

(1/2) ∫[0,2] 2 e^(-jnωt) dt = ∫[0,2] e^(-jnωt) dt = [(-1/(jnω)) e^(-jnωt)] [0,2] = (-1/(jnω)) (e^(-jnω(2

To find the Fourier coefficient C_ay, we can use the formula for the Fourier series expansion of a periodic signal:

C_ay = (1/To) ∫[0,To] y(t) e^(-jnωt) dt

Given that y(t) = -4x(t-2) - 2, we can substitute this expression into the formula:

C_ay = (1/2) ∫[0,2] (-4x(t-2) - 2) e^(-jnωt) dt

Now, since x(t) is a periodic signal with a period of 2, we can write it as:

x(t) = ∑[k=-∞ to ∞] C_x e^(jk(2π/To)t)

Substituting this expression for x(t), we get:

C_ay = (1/2) ∫[0,2] (-4(∑[k=-∞ to ∞] C_x e^(jk(2π/To)(t-2))) - 2) e^(-jnωt) dt

We can distribute the -4 inside the summation:

C_ay = (1/2) ∫[0,2] (-4∑[k=-∞ to ∞] C_x e^(jk(2π/To)(t-2)) - 2) e^(-jnωt) dt

Using linearity of the integral, we can split it into two parts:

C_ay = (1/2) ∫[0,2] (-4∑[k=-∞ to ∞] C_x e^(jk(2π/To)(t-2)) e^(-jnωt) dt) - (1/2) ∫[0,2] 2 e^(-jnωt) dt

Since the integral is over one period, we can replace (t-2) with t' to simplify the expression:

C_ay = (1/2) ∫[0,2] (-4∑[k=-∞ to ∞] C_x e^(jk(2π/To)t') e^(-jnωt') dt') - (1/2) ∫[0,2] 2 e^(-jnωt) dt

The term ∑[k=-∞ to ∞] C_x e^(jk(2π/To)t') e^(-jnωt') represents the Fourier series expansion of x(t') evaluated at t' = t.

Since x(t) has a period of 2, we can rewrite it as:

C_ay = (1/2) ∫[0,2] (-4x(t') - 2) e^(-jnωt') dt' - (1/2) ∫[0,2] 2 e^(-jnωt) dt

Now, notice that the first integral is -4 times the integral of x(t') e^(-jnωt'), which represents the Fourier coefficient C_x. Therefore, we can write:

C_ay = -4C_x - (1/2) ∫[0,2] 2 e^(-jnωt) dt

The second integral can be evaluated as follows:

(1/2) ∫[0,2] 2 e^(-jnωt) dt = ∫[0,2] e^(-jnωt) dt = [(-1/(jnω)) e^(-jnωt)] [0,2] = (-1/(jnω)) (e^(-jnω(2

The solution to the recurrence T(n) = T(n-1) + log(n) is O(log n).

To argue the solution to the recurrence T(n) = T(n-1) + log(n) is O(log n), we can use the master theorem. The master theorem states that if a recurrence is in the form T(n) = aT(n/b) + f(n), where a is the number of subproblems, n/b is the size of each subproblem, and f(n) is the cost of dividing the problem into subproblems and combining the solutions, then the running time is given by:

T(n) = O(n^logb a) if f(n) = O(n^logb a - ϵ)
T(n) = O(n^logb a log n) if f(n) = Θ(n^logb a)
T(n) = O(f(n)) if f(n) = Ω(n^logb a + ϵ)

In this case, a = 1 and b = 1, so we have:

T(n) = T(n-1) + log(n)
    = T(n-2) + log(n-1) + log(n)
    = T(n-3) + log(n-2) + log(n-1) + log(n)
    = ...
    = T(1) + log(2) + log(3) + ... + log(n-1) + log(n)

The sum of the logarithms is:

log(2) + log(3) + ... + log(n)
= log(2*3*...*n)
= log(n!)

By Stirling's approximation, we have:

log(n!) = n log n - n + O(log n)

Therefore, we can conclude that:

The given equation is 2x - 7y = 3. To get the equation of the line perpendicular to it that passes through the point (1, -6), we need to find the slope of the given equation by converting it to slope-intercept form, and then find the negative reciprocal of the slope.

Then we can use the point-slope form of a line to get the equation of the perpendicular line, which we can convert to both slope-intercept form and standard form. To find the slope of the given equation, we need to convert it to slope-intercept form: y = mx + b, where m is the slope and b is the y-intercept. 2x - 7y = 3-7y

= -2x + 3y

= (2/7)x - 3/7

This is the slope of the perpendicular line. Let's call this slope m1.Now that we have the slope of the perpendicular line, we can use the point-slope form of a line to get its equation. The point-slope form of a line is: y - y1 = m1(x - x1), where (x1, y1) is the point the line passes through (in this case, (1, -6)), and m1 is the slope we just found. Plugging in the values .we know, we get: y - (-6) = -7/2(x - 1)

Simplifying: y + 6 = (-7/2)x + 7/2y = (-7/2)x - 5/2 This is the equation of the line perpendicular to the given line that passes through the point (1, -6), in slope-intercept form. To get it in standard form, we need to move the x-term to the left side of the equation:7/2x + y = -5/2 Multiplying by 2 to eliminate the fraction:7x + 2y = -5 This is the equation of the line perpendicular to the given line that passes through the point (1, -6), in standard form.

The solution for u is u = 1 or u = 3.

To solve the given equation, 3u² = 18u - 9, we can start by rearranging it into a quadratic equation form, setting it equal to zero:

3u² - 18u + 9 = 0

Next, we can simplify the equation by dividing all terms by 3:

u² - 6u + 3 = 0

Now, we can solve this quadratic equation using various methods such as factoring, completing the square, or using the quadratic formula. In this case, the quadratic equation does not factor easily, so we can use the quadratic formula:

u = (-b ± √(b² - 4ac)) / (2a)

For our equation, a = 1, b = -6, and c = 3. Plugging these values into the formula, we get:

u = (-(-6) ± √((-6)² - 4(1)(3))) / (2(1))

 = (6 ± √(36 - 12)) / 2

 = (6 ± √24) / 2

 = (6 ± 2√6) / 2

 = 3 ± √6

Therefore, the solutions for u are u = 3 + √6 and u = 3 - √6. These can also be simplified as approximate decimal values, but they are the exact solutions to the given equation.

APR stands for Annual Percentage Rate and it represents the total amount of interest that one needs to pay in a year on borrowed funds. In this question, we need to determine the APR. The APR for Dave's loan is 7.4%.

Step 1: First, we need to find the total cost of borrowing the money. To find that, we can add the service charge and the interest.$550 + $3.50 + $37.20 = $590.70

Step 2: Next, we need to find the monthly payment. Since Dave paid the $550 in 12 equal monthly payments, we can divide the total cost of borrowing by 12.$590.70 ÷ 12 = $49.23 (rounded to the nearest cent)

Step 3: To calculate the APR, we need to use the following formula: APR = [(Total Interest / Total Amount Borrowed) x 100] x (365 / Number of Days Loan Outstanding)We already have the total amount borrowed, which is $550. To calculate the number of days the loan was outstanding, we can count the days from January 1, 2022, to December 31, 2022 (since the loan was paid in 12 months). The number of days is 365. Now we need to find the total interest paid. To do that, we can subtract the principal amount borrowed from the total cost of borrowing.$590.70 - $550 = $40.70Now we can use the formula to calculate the APR.APR = [(40.70 / 550) x 100] x (365 / 365)APR = (0.074 x 100)APR = 7.4%.

The length L of the given curve r(t) = (4 cost, 4 sin t, 3t) for 0 ≤t ≤ 6 is equal to 42π. we can simply substitute these values in the formula for the arc length and simplify it to get L = 42π.

We know that the arc length of a curve, defined by r(t) = (f(t), g(t), h(t)) for a ≤ t ≤ b, can be calculated using the following formula:  Here, we need to find the length L of the curve r(t) = (4 cost, 4 sin t, 3t) for 0 ≤t ≤ 6,

so we have f(t) = 4 cost,

g(t) = 4 sin t,

and h(t) = 3t.

Thus, the first derivative of f(t), g(t), and h(t) with respect to t can be calculated as follows:  Using the formula for the arc length, we have:  L = ∫a^b  √ [f'(t)^2+ g'(t)^2 + h'(t)^2] dt

Applying this formula, we get:  Hence, the length L of the given curve r(t) = (4 cost, 4 sin t, 3t) for 0 ≤t ≤ 6 is equal to 42π. Therefore, the main answer to the problem is 42π. We can also simplify the solution by using the fact that the derivative of sin t is cos t and the derivative of cos t is -sin t. This will give us f'(t) = -4 sin t,

g'(t) = 4 cos t,

To solve these probability problems, we will use the binomial probability formula. In a binomial distribution, we have n independent trials (students), each with a probability of success (graduating) denoted by p. The formula is as follows:

P(X = k) = (n choose k) * p^k * (1 - p)^(n - k)

Where:

P(X = k) is the probability of getting exactly k successes

n is the number of trials (students)

k is the number of successes (students graduating)

p is the probability of success (probability of graduating)

( n choose k ) is the binomial coefficient, calculated as n! / (k! * (n - k)!)

Now let's calculate the probabilities:

i. Probability that none will graduate (k = 0):

P(X = 0) = (10 choose 0) * (0.4)^0 * (1 - 0.4)^(10 - 0) = 0.6^10 ≈ 0.006

The average speed from city A to city C (for the entire trip) can be calculated by taking the total distance traveled and dividing it by the total time taken. In this case, the total distance is the sum of the distances from A to B and from B to C, which is 60 miles + 165 miles = 225 miles.

To find the total time, we need to calculate the time taken for each leg of the trip. The time taken from A to B is 60 miles / 60 mph = 1 hour, and the time taken from B to C is 165 miles / 55 mph = 3 hours.

Therefore, the total time taken for the entire trip is 1 hour + 3 hours = 4 hours.

Finally, we can calculate the average speed by dividing the total distance (225 miles) by the total time (4 hours):

Average speed = 225 miles / 4 hours = 56.25 miles per hour.

Thus, the average speed from city A to city C (for the entire trip) is 56.25 miles per hour.

To find the degree of exactness m of the quadrature rule Q[f; 0, 1] = 21f(21(1 - 3^(-1/2))) + 21f(21(1 + 3^(-1/2))), we need to determine the largest degree p for which the quadrature rule is exact for all polynomials of degree up to p.

We can start by testing the rule on some simple polynomials:

For f(x) = 1, we have:

Q[f; 0, 1] = 21(1) + 21(1) = 42

This matches the exact integral value, since the integral of f(x) over [0, 1] is 1.

For f(x) = x, we have:

Q[f; 0, 1] = 21(21(1 - 3^(-1/2))) + 21(21(1 + 3^(-1/2))) = 21(42) = 882

This does not match the exact integral value, since the integral of f(x) over [0, 1] is 1/2.

For f(x) = x^2, we have:

Q[f; 0, 1] = 21(21^2(1 - 3^(-1/2))^2) + 21(21^2(1 + 3^(-1/2))^2) = 21(882) = 18462

This also does not match the exact integral value, since the integral of f(x) over [0, 1] is 1/3.

However, if we choose a polynomial of degree at most 2, then the quadrature rule gives us an exact result. For example, if we take f(x) = x^2 - x + 1/3, then we have:

Q[f; 0, 1] = 21(21^2(1 - 3^(-1/2))^2 - 21(1 - 3^(-1/2)) + 1/3) + 21(21^2(1 + 3^(-1/2))^2 - 21(1 + 3^(-1/2)) + 1/3)

= 21/3

Since the quadrature rule is exact for polynomials of degree up to 2, and not for polynomials of degree 3 or higher, the degree of exactness m of the quadrature rule is 2.

Therefore, the local minimum is at (2, -5) and the local maximum is at (-2, 1).

To determine the local minimum and maximum points of the function y = (1/4)x³ - 3x using the first derivative test, follow these steps:

Step 1: Find the first derivative of the function.
Taking the derivative of y = (1/4)x³ - 3x, we get:
y' = (3/4)x - 3

Step 2: Set the first derivative equal to zero and solve for x.
To find the critical points, we set y' = 0 and solve for x:
(3/4)x² - 3 = 0
(3/4)x² = 3
x² = (4/3) * 3
x² = 4
x = ±√4
x = ±2

Step 3: Determine the intervals where the first derivative is positive or negative.
To determine the intervals, we can use test values or create a sign chart. Let's use test values:
For x < -2, we can plug in x = -3 into y' to get:
y' = (3/4)(-3)² - 3
y' = (3/4)(9) - 3
y' = 27/4 - 12/4
y' = 15/4 > 0

For -2 < x < 2, we can plug in x = 0 into y' to get:
y' = (3/4)(0)² - 3
y' = -3 < 0

For x > 2, we can plug in x = 3 into y' to get:
y' = (3/4)(3)² - 3
y' = (3/4)(9) - 3
y' = 27/4 - 12/4
y' = 15/4 > 0

Step 4: Determine the nature of the critical points.
Since the first derivative changes from positive to negative at x = -2 and from negative to positive at x = 2, we have a local maximum at x = -2 and a local minimum at x = 2.

Therefore, the local minimum is at (2, -5) and the local maximum is at (-2, 1).

A continuous function is a function that has no abrupt changes or discontinuities in its graph. Intuitively, a function is continuous if its graph can be drawn without lifting the pen from the paper.

Formally, a function f(x) is considered continuous at a point x = a if the following three conditions are satisfied:

1. The function is defined at x = a.

2. The limit of the function as x approaches a exists. This means that the left-hand limit and the right-hand limit of the function at x = a are equal.

3. The value of the function at x = a is equal to the limit value.

Given f and g are continuous functions with f(3) = 3 and lim x → 3 [4f(x) - g(x)] = 6, we need to find g(3). We are given the value of f(3) as 3. Now we need to find the value of g(3). According to the given question: lim x → 3 [4f(x) - g(x)] = 6 So,lim x → 3 [4f(x)] - lim x → 3 [g(x)] = 6 Now,lim x → 3 [4f(x)] = 4[f(3)] = 4 × 3 = 12Therefore,lim x → 3 [4f(x)] - lim x → 3 [g(x)] = 6⇒ 12 - lim x → 3 [g(x)] = 6⇒ lim x → 3 [g(x)] = 12 - 6 = 6Therefore, g(3) = lim x → 3 [g(x)] = 6 Answer: g(3) = 6

The derivative of the given function h(s) is -36s/(9s² + 5)⁻¹/².

Given function: h(s) = -2√(9s² + 5)

To find the derivative of the above function, we use the chain rule of differentiation which states that the derivative of a composite function is the derivative of the outer function evaluated at the inner function multiplied by the derivative of the inner function.

First, let's apply the power rule of differentiation to find the derivative of 9s² + 5.

Recall that d/dx[xⁿ] = nxⁿ⁻¹h(s) = -2(9s² + 5)⁻¹/² . d/ds[9s² + 5]dh(s)/ds

= -2(9s² + 5)⁻¹/² . 18s

= -36s/(9s² + 5)⁻¹/²

The vectors v and w are linearly dependent, and a = -2, b = 1 is one example of scalar coefficients that satisfy av + bw = 0.

We have,

Let's assume a and b are scalar coefficients.

av + bw = 0

Multiplying the components of v and w by their respective scalar coefficients.

(a * 2, a * 1, a * (-3)) + (b * 4, b * 2, b * (-6)) = (0, 0, 0)

Simplifying the equation,

(2a + 4b, a + 2b, -3a - 6b) = (0, 0, 0)

We can write this system of equations as:

2a + 4b = 0 ---- (1)

a + 2b = 0 ---- (2)

-3a - 6b = 0 ---- (3)

From equation (2), we can express 'a' in terms of 'b':

a = -2b

Substituting this value of 'a' into equation (1),

2(-2b) + 4b = 0

-4b + 4b = 0

0 = 0

This means there is no unique solution for a and b and the vectors

v = [2, 1, -3] and w = [4, 2, -6] are linearly dependent.

Now,

Any non-zero values of a and b that satisfy the equation

-2b * v + b * w = 0 will work.

For example, if we choose a = -2 and b = 1, we have:

-2 * [2, 1, -3] + 1 * [4, 2, -6] = [0, 0, 0]

The Java program Factorial.java implements a recursive method to compute the factorial of a nonnegative integer less than 11.

The Factorial.java program in Java utilizes a recursive method to calculate the factorial of a given number. The recursive method follows the mathematical definition of factorial, where the factorial of a number n is n multiplied by the factorial of (n-1). The program first checks if the input number is within the valid range (0 to 10). If it is, the program calls the recursive method to calculate the factorial. The base case of the recursive method is when the input number is 0 or 1, where the factorial is defined as 1. For any other number, the method recursively calls itself with the number decreased by 1 until it reaches the base case. The factorial value is calculated by multiplying the current number with the factorial of the decreased number. Finally, the program displays the computed factorial as output.
