Answer: Tavion is traveling faster than Jonathan, but Tavion is slowing down slightly.
Their initial speeds are:
Jonathan 0.667 miles per minute.
Tavion 0.833 miles per minute.
Step-by-step explanation: To find their speed, divide miles by minutes.
From the graph pick coordinates. (3,2) or (6,4) The y-values are miles, x-values are minutes.
Jonathan: 2 miles ÷ 3 minutes = 0.667 miles per minute.
For Tavion, get his initial speed from the first values in the chart.
Tavion: 12.5 miles ÷ 15 minutes = 0.833 miles per minute.
The miles do not increase exactly as the time increased. They would be 12.5, 25 and 37.5 if his initial speed remained the same.

samples of size 10 are selected from a manufacturing process. the mean of the sample ranges is 0.8. what is the estimate of the standard deviation of the population? (round your answer to 3 decimal places.)
The estimated standard deviation of the population is approximately 0.133 (rounded to 3 decimal places).
To estimate the standard deviation of the population, we will use the formula of the standard deviation using the sample means, also known as the standard error. The formula gives the standard error (SE):
SE = (s / √n)
Where:
s is the standard deviation of the sample means
n is the sample size
In this case, we know, the mean of the sample ranges is 0.8, but we don't have the exact sample data. As a result, we are unable to calculate the standard deviation (s).
However, we can an assumption that the sample ranges are normally distributed, which gives us the idea to use the relationship between the range and the standard deviation. For normally distributed data, the range is approximately equal to 6 times the standard deviation. Mathematically, we can express this as:
Range ≈ 6s
Given that the mean of the sample ranges is 0.8, we have the following:
0.8 ≈ 6s
Now, let's solve for s:
s ≈ 0.8 / 6 ≈ 0.133
So, the estimate of the population's standard deviation is approximately 0.133 (rounded to 3 decimal places).

b. For the following input signal
x(t) = 】[8(t−1−3k) – 8(t−2 − 3k)] k=-[infinity]o
i. Sketch the signal x(t). [1.5 points]
ii. Find the Exponential Fourier series of x(t). [1.5 points]
iii. Let Yk represent the Exponential Fourier series coefficients of the resulting output. Determine Y₁. [2 points]
The Fourier series coefficients can be calculated using the formula:
Ck = (1/T) * ∫[x(t) * exp(-jkω0t)] dt
To sketch the signal x(t), let's analyze it step by step.
i. Sketching the signal x(t):
The given input signal x(t) is defined as:
x(t) = 8(t - 1 - 3k) - 8(t - 2 - 3k), where k = -∞ to 0.
Let's consider different cases based on the values of t:
Case 1: When t < 1 - 3k:
In this case, both terms inside the brackets become negative, resulting in x(t) = 8(0) - 8(0) = 0.
Case 2: When 1 - 3k < t < 2 - 3k:
In this case, the first term inside the brackets becomes positive and the second term inside the brackets becomes negative. Therefore, x(t) = 8(t - 1 - 3k) + 8(0) = 8(t - 1 - 3k).
Case 3: When t > 2 - 3k:
In this case, both terms inside the brackets become positive, resulting in x(t) = 8(t - 1 - 3k) - 8(t - 2 - 3k) = 0
ii. Finding the Exponential Fourier series of x(t):
To find the Exponential Fourier series coefficients, we need to calculate the complex exponential Fourier series representation of the signal x(t).
The complex exponential Fourier series representation of a periodic signal x(t) with period T can be expressed as:
x(t) = ∑[Ck * exp(jkω0t)]
where Ck represents the Fourier series coefficients, j is the imaginary unit, k is an integer, and ω0 = 2π/T.
In this case, the signal x(t) is not periodic, but we can still find the Fourier series coefficients for a single period.
Given the input signal x(t), we can see that it consists of two rectangular pulses:
The first pulse starts at t = 1 - 3k and ends at t = 2 - 3k.
The second pulse starts at t = 2 - 3k and ends at t = 3 - 3k.
Therefore, for a single period, we can express x(t) as a sum of these two pulses:
x(t) = 8(t - 1 - 3k) - 8(t - 2 - 3k) = 8(t - 1 - 3k) for 1 - 3k < t < 2 - 3k
Now, we need to find the Fourier series coefficients Ck for this pulse.
The Fourier series coefficients can be calculated using the formula:
Ck = (1/T) * ∫[x(t) * exp(-jkω0t)] dt
Since we have a single period between t = 1 - 3k and t = 2 - 3k, we can take the period T = 1.
Now, let's calculate the Fourier series coefficients for the given signal:
Ck = (1/1) * ∫[8(t - 1 - 3k) * exp(-jk2πt)] dt
Ck = 8 * ∫[(t - 1 - 3k) * exp(-jk2πt)] dt

how many 4 digit numbers n have the property that the 3 digit number obtained by removing the leftmost digit is one ninth of n
Answer:
7
Step-by-step explanation:
We want to find the number 4-digit of positive integers n such that removing the thousands digit divides the number by 9.
__
Let the thousands digit be 'd'. Then we want to find the integer solutions to ...
n -1000d = n/9
n -n/9 = 1000d . . . . . . add 1000d -n/9
8n = 9000d . . . . . . . . multiply by 9
n = 1125d . . . . . . . . . divide by 8
The values of d that will give a suitable 4-digit value of n are 1 through 7.
When d=8, n is 9000. Removing the 9 gives 0, not 1000.
When d=9, n is 10125, not a 4-digit number.
There are 7 4-digit numbers such that removing the thousands digit gives 1/9 of the number.

which function(s) has the following properties? there may be more than one answer, so select all that apply. . domain is all real numbers, . range is all integers, . g
The correct answer is option c. There are no real-valued functions that have a domain of all real numbers and a range of all integers.
A function maps an input (or domain) to a unique output (or range). In order for a function to have a domain of all real numbers, it must take any real number as an input and provide a unique output. However, for a function to have a range of all integers, it must be the case that every output is an integer.
Since the real numbers are not countable and the integers are countable, there can be no function that maps every real number to a unique integer. In other words, there is no one-to-one correspondence between the real numbers and the integers, which means that it is not possible to find a function that maps every real number to an integer.

determine whether the given function is continuous on its domain. if it is not continuous, determine all points of discontinuity (a) f (x)
A function is a relationship or expression involving one or more variables. It has a set of inputs and outputs. Each input has only one output. The function is the description of how the inputs relate to the output.
Let's verify whether the given function is continuous or not at x = 3.
If the function is continuous at x = 3, then it should be possible to evaluate f(3) without using limits.
f(3) = (32 - 9) / (3 - 3) = (0 / 0), which is undefined.
Therefore, f (x) is not continuous at x = 3.
Now, let's find the limit of f (x) as x approaches 3.
To do this, we will factorize the numerator and simplify the expression:
f(x) = (x^2 - 9) / (x - 3)f(x)
= [(x - 3)(x + 3)] / (x - 3)
Now, (x - 3) cancels out and we get:f(x) = x + 3
Therefore, lim f(x) as x approaches 3 is 3 + 3 = 6.
So, we can say that the given function f(x) = (x2 - 9) / (x - 3) is not continuous at x = 3, but the limit of f(x) as x approaches 3 exists and is equal to 6.
Therefore, the point of discontinuity of f (x) is x = 3.

Answer:
(3, - 1 )
Step-by-step explanation:
Given the 2 equations
2x + 3y = 3 → (1)
x + 6y = - 3 → (2)
Multiplying (1) by - 2 and adding to (2) will eliminate the y- term
- 4x - 6y = - 6 → (3)
Add (2) and (3) term by term eliminating y
- 3x = - 9 ( divide both sides by - 3 )
x = 3
Substitute x = 3 into either of the 2 equations and solve for y
Substituting into (2)
3 + 6y = - 3 ( subtract 3 from both sides )
6y = - 6 ( divide both sides by 6 )
y = - 1

Tammy is at the dentist's office waiting on her appointment. She notices that the 6-inch long minute hand is rotating around the clock and marking off time like degrees on a unit circle. Part 1: How many radians does the minute hand move from 1:20 to 1:55? Part 2: How far does the tip of the minute hand travel during that time?
Answer:
Part 1:
From 1:20 to 1:55 is a total of 35 minutes. Since the minute hand completes one full rotation in 60 minutes, it moves halfway around the clock during this time. Therefore, the minute hand moves pi (or 180 degrees) radians.
Answer: pi (or 180 degrees)Part 2:
Since the minute hand has a length of 6 inches, we can use the formula for the circumference of a circle to find how far the tip of the minute hand travels during this time.
C = 2pir
C = 2pi6
C = 12pi
So the tip of the minute hand travels a total distance of 12pi inches during the 35 minutes from 1:20 to 1:55.
