24.1 let fn(x) = 1 2 cos2 √ nx n . prove carefully that (fn) converges uniformly to 0 on r.
Answers
We need to prove that the sequence of functions fn(x) = (1/2)cos^2(√nx) converges uniformly to 0 on the real numbers.
To prove uniform convergence, we need to show that for any ε > 0, there exists a positive integer N such that |fn(x) - 0| < ε for all n > N and for all x in the real numbers.
Given fn(x) = (1/2)cos^2(√nx), we observe that as n increases, the argument √nx inside the cosine function becomes larger, causing the cosine to oscillate more rapidly between 0 and 1. Since we are multiplying the cosine by (1/2) and taking its square, fn(x) gradually approaches 0 as n increases.
To formally prove uniform convergence, we can start by fixing ε > 0 and then choose N such that √Nx > 1/ε. By selecting this N, we can show that for all n > N, |fn(x) - 0| < ε for any x in the real numbers. This demonstrates that the sequence of functions fn(x) converges uniformly to 0 on the real numbers.

Consider the arithmetic sequence presented in the table below. What is the first term, ay, and the 22nd term of the sequence? n 4 37 an 16 115 Hint: Q, = a1 + d(n-1), where ay is the first term and d is the common difference. O a = 7, 222 - 68 O a = 3, 222 150 O a = 3, 222 = 148 O Qı = 7, 222 = 70
Answers
The first term of the arithmetic sequence is 16 and the 22nd term is 148.
To solve for the first term, we can use the following formula:
a_n = a_1 + d(n-1)
where:
a_n is the nth term of the sequence
a_1 is the first term of the sequence
d is the common difference of the sequence
We know that the 4th term is 16 and the 37th term is 115. We can use these values to solve for d.
d = a_{37} - a_4 = 115 - 16 = 99
Now that we know d, we can solve for a_1 using the value of the 4th term.
a_1 = a_4 - d = 16 - 99 = -83
Finally, we can solve for the 22nd term using the value of a_1 and d.
a_{22} = a_1 + d(22-1) = -83 + 99(21) = 148
Therefore, the first term of the arithmetic sequence is 16 and the 22nd term is 148.
Here is a more detailed explanation of the solution:
The first step is to identify the common difference of the sequence. This can be done by subtracting any two consecutive terms in the sequence. In this case, the 4th term is 16 and the 37th term is 115. Subtracting these two terms, we get 115 - 16 = 99. This is the common difference of the sequence.
Once we know the common difference, we can solve for the first term by using any of the terms in the sequence. In this case, we will use the 4th term. The formula for the nth term of an arithmetic sequence is a_n = a_1 + d(n-1), where a_n is the nth term, a_1 is the first term, and d is the common difference. Substituting the 4th term, the common difference, and n = 4, we get a_4 = a_1 + d(4-1). Simplifying this equation, we get 16 = a_1 + 99. Solving for a_1, we get a_1 = -83.
Finally, we can solve for the 22nd term by using the first term and the common difference. The formula for the nth term of an arithmetic sequence is a_n = a_1 + d(n-1). Substituting the first term, the common difference, and n = 22, we get a_{22} = -83 + 99(22-1). Simplifying this equation, we get a_{22} = 148.
Therefore, the first term of the arithmetic sequence is 16 and the 22nd term is 148.

Use the Singapore Bar Method, including drawings, to solve the following problem. Identify the unit value when appropriate, including labels. The sides of the triangle are in the ratio 5:7:8 and the longest side is 36 cm longer than the shortest side. Find the perimeter of the triangle.
Answers
When the sides of the triangle are in the ratio 5:7:8 and the longest side is 36 cm longer than the shortest side, the perimeter is 240cm.
How to calculate the perimeterLet's assume the shortest side of the triangle has a length of x cm. According to the given ratio, the sides of the triangle are in the ratio 5:7:8. Therefore, the lengths of the sides can be expressed as:
Shortest side: 5x
Second side: 7x
Longest side: 8x
We are also given that the longest side is 36 cm longer than the shortest side. So we can set up the following equation:
8x = 5x + 36
Now, let's solve this equation to find the value of x:
8x - 5x = 36
3x = 36
x = 36 / 3
x = 12
Now we can substitute this value back into the expressions for the side lengths to find their actual lengths:
Shortest side: 5x = 5 * 12 = 60 cm
Second side: 7x = 7 * 12 = 84 cm
Longest side: 8x = 8 * 12 = 96 cm
Finally, we can calculate the perimeter of the triangle by adding the lengths of all three sides:
Perimeter = Shortest side + Second side + Longest side
= 60 cm + 84 cm + 96 cm
= 240 cm
Therefore, the perimeter of the triangle is 240 cm.

2. Find the solution to the recurrence relation bn = 4bn-1-4bn-2 with initial values bo = 1 and b₁ = 2.
Answers
The resultant of the recurrence relation bn = 4bn-1-4bn-2 with initial values bo = 1 and b₁ = 2 is bn = (1 + (n/2)) 2ⁿ.
The given recurrence relation is
bn = 4bn-1 - 4bn-2 with initial values bo = 1 and b₁ = 2. Now, we have to find the solution to the recurrence relation. It can be observed that the given recurrence relation is a second-order recurrence relation. The characteristic equation of the recurrence relation is given by:
r² = 4r - 4, which can be simplified as r² - 4r + 4 = 0. We need to solve this equation. It can be solved as r = 2
The characteristic equation of the given recurrence relation has two equal roots r1 = r2 = 2. Therefore, the general result of the recurrence relation is given by:
bn = (A + Bn) 2ⁿ
For the given initial values b₀ = 1, and b₁ = 2 we can write:
b₀ = (A + B(0)) 2⁰ => A = 1b₁ = (A + B(1)) 2¹ => A + 2B = 2
On solving these equations, we get A = 1 and B = 1/2
The resultant to the recurrence relation is:
bn = (1 + (n/2)) 2ⁿ

Answers
To analyze the motor fuel octane ratings data, we can start by constructing a frequency distribution and then use it to create a histogram.
The frequency distribution will provide information about the distribution of the data across different octane rating ranges, while the histogram visually represents the distribution graphically.
a. To construct a frequency distribution, we divide the data into bins and count the frequency of values falling within each bin. In this case, we will use 8 bins. We determine the lower and upper limits for each bin and calculate the midpoint by averaging the limits. Then, we count the number of values within each bin and calculate the relative frequency by dividing the frequency by the total number of values.
b. Once the frequency distribution is constructed, we can use it to create a histogram. The histogram represents the frequency or relative frequency of values within each bin as vertical bars. The bins are plotted along the x-axis, and the height of the bars represents the frequency or relative frequency on the y-axis. The histogram allows us to visualize the distribution pattern of the motor fuel octane ratings data, showing if it is skewed, symmetric, or has other characteristics.
By constructing a frequency distribution and creating a histogram, we can gain insights into the distribution of the motor fuel octane ratings data. The frequency distribution table provides a summarized view of how the data is spread across different octane rating ranges, while the histogram visually represents the same information in a graphical form. Both the frequency distribution and the histogram aid in understanding the distribution pattern, identifying potential outliers or gaps, and informing further analysis or decision-making related to the data.

Answers
The sample mean of the given data series is 33.7 and the population mean is 35.86. The difference between the two quantities, rounded to two decimal places, is -2.16.
Sample mean and population mean are important terms in statistics. The sample mean is the average of a set of data taken from a larger population, while the population mean is the average of an entire population.
To find the sample mean of the given data series, we add up all the values and divide by the total number of values. Therefore,
Sample mean = (15+26+25+23+26+28+20+20+31+45+32+41+54+23+45+24+90+19+16+75+29) / 21
Sample mean = 33.7
To find the population mean, we use the same formula but with all the values of the population included. Therefore,
Population mean = (15+26+25+23+26+28+20+20+31+45+32+41+54+23+45+24+90+19+100+75+29) / 21
Population mean = 35.86
Finally, to find the difference between the two quantities, we subtract the sample mean from the population mean. Therefore,
Difference = Population mean - Sample mean
Difference = 35.86 - 33.7
Difference = -2.16 (rounded to two decimal places)
Therefore, the difference between the sample mean and population mean is -2.16.

Consider the curve defined by the equation y = 47° +10x. Set up an integral that represents the length of curve from the point (-3,6) to the point (2,36).
Answers
The integral that represents the length of the curve from the point (-3,6) to the point (2,36) is L = ∫[-3 to 2] √101 dx.
To find the length of the curve defined by the equation y = 47° + 10x from the point (-3,6) to the point (2,36), we can use the arc length formula for a curve:
L = ∫[a to b] √(1 + (dy/dx)^2) dx
First, let's find dy/dx by taking the derivative of the given equation:
dy/dx = d/dx(47° + 10x) = 10
Now we can substitute this value into the arc length formula:
L = ∫[-3 to 2] √(1 + (10)^2) dx
Simplifying:
L = ∫[-3 to 2] √(1 + 100) dx
L = ∫[-3 to 2] √101 dx
Thus, the integral that represents the length of the curve from the point (-3,6) to the point (2,36) is:
L = ∫[-3 to 2] √101 dx
