Kristin boards a ferris wheel with a radius of 13 meters at the 3-o'clock position and rides it for one full rotation. To represent the distance Kristin has traveled along the circular path since the ride started, we use s. We are asked to imagine an angle centered at the ferris wheel's center that subtends the path Kristin travels. This can be solved by the concept of Circles.

Let's start by drawing a diagram of the situation. We draw a circle with a radius of 13 meters to represent the ferris wheel. We place Kristin at the 3-o'clock position on the circle. To represent the distance Kristin has traveled, we draw a line segment from the center of the circle to a point on the circle where Kristin currently is. Let's call this point P. We label the length of this line segment as s.

Now, we know that Kristin rides the ferris wheel for one full rotation. This means that the ferris wheel also makes a full rotation. Therefore, the angle subtended by the path Kristin travels is 360 degrees.

To find the length of s, we need to use some trigonometry. We can see that triangle OAP (where O is the center of the circle) is a right-angled triangle, with OA being the radius of the circle and OP being s. We can use the Pythagorean theorem to find the length of AP:

AP^2 = OA^2 - OP^2

AP^2 = 13^2 - s^2

AP = sqrt(169 - s^2)

Now, we can use trigonometry to find the length of s. We know that the angle subtended by the path Kristin travels is 360 degrees, or 2π radians. Therefore, the angle subtended by arc AP is also 2π radians. We can use the formula for the length of an arc:

length of arc = radius x angle in radians

So, we have:

AP = radius x angle in radians

sqrt(169 - s^2) = 13 x 2π

169 - s^2 = 169π^2

s^2 = 169 - 169π^2

s ≈ 19.6 meters

Therefore, Kristin travels approximately 19.6 meters along the circular path during the ride.

To find the value of s3 in the given sigma summation series and calculate the truncation error, let's first analyze the series and determine its pattern.

The series can be written as:

s = (0.2 * 1) / 0.8 + (0.2 * 2) / 0.8 + (0.2 * 3) / 0.8 + ...

We notice that each term in the series has the form (0.2 * n) / 0.8. We can simplify this expression by dividing both the numerator and denominator by 0.2:

s = n / 4

Now, let's calculate s3 by substituting n = 3:

s3 = 3 / 4

s3 = 0.75

So, the value of s3 in the series is 0.75.

Now, let's calculate the truncation error. The truncation error is the difference between the actual sum of the series and the sum obtained by truncating or stopping at a certain term.

Given that the series sum is 0.3125 and we have s3 = 0.75, we can calculate the truncation error:

Truncation error = |Actual sum - Sum truncated at s3|

Truncation error = |0.3125 - 0.75|

Truncation error = |-0.4375|

Truncation error = 0.4375

The truncation error in this case is 0.4375.

Answer:

SAS, because vertical angles are congruent.

The momentum magnitude observed in frame s' is √(15m^2c^4).

In special relativity, the relationship between energy (E) and momentum (p) is given by the equation:

E^2 = (pc)^2 + (mc^2)^2

where m is the rest mass of the particle, c is the speed of light, and p is the momentum of the particle.

In frame of reference s, the energy of the electron is given as 4mc^2. Plugging this into the equation, we have:

(4mc^2)^2 = (pc)^2 + (mc^2)^2

Simplifying this equation, we get:

16m^2c^4 = p^2c^2 + m^2c^4

Canceling out the common terms, we have:

15m^2c^4 = p^2c^2

Taking the square root of both sides, we get:

pc = √(15m^2c^4)

The momentum magnitude observed in frame s', denoted as p', is related to the momentum in frame s (p) by the relativistic velocity addition formula:

p' = γ(p - βE/c)

where γ is the Lorentz factor and β is the velocity of frame s' relative to frame s. Since the electron is moving along the x-axis, the velocity β is zero, and the Lorentz factor γ is equal to 1.

Therefore, the momentum magnitude observed in frame s' is the same as the momentum magnitude in frame s:

p' = p

the expected number of customers in the post office in steady state is 13.16.

We can use the M/M/1 queue model to solve this problem. Since customers arrive at a Poisson rate of 18 per hour, the arrival rate is λ = 18/60 = 0.3 customers per minute. The service times are deterministic, so we can use the mean service time to calculate the service rate. The mean service time is:

(0.5 x 2) + (0.2 x 3) + (0.3 x 5) = 3.1 minutes

So the service rate is μ = 1/3.1 = 0.3226 customers per minute.

The utilization of the system is ρ = λ/μ = 0.3/0.3226 = 0.929. Since the system is stable, the expected number of customers in the system in steady state is:

L = ρ/(1 - ρ) = 0.929/(1 - 0.929) = 13.16 customers

What is the system of equations?

A system of equations also referred to as an equation system, is a collection of finite equations for which common solutions are sought.

Here, we have

Given :

Madi has $8.80 in pennies and nickels.

If there are twice as many nickels as pennies.

We have to find out how many pennies and nickels Madi has.

And pennies = $0.01 and a nickel = $0.05.

If there are twice as many nickels as pennies n= 2p, and the total value is $8.80.

Then equation becomes;

$0.01p + $0.05n = $8.80.

Substitute the value of 2p = n in the given equation,

$0.01p + $0.05(2p) = $8.80

$0.01p + $0.10p = $8.80

$0.11p = $8.80

p = $8.80/$0.11

p = 80

And put the value of p=8 in the equation,

We get,

n = 2p = 2(80) = 160

Hence, there are p=80 pennies and n=160 nickels.

The larger expected loss is in a 25% chance to lose nothing, and a 75% chance of losing $1000.

To determine which option has a larger expected loss, we need to calculate the expected value of each option.

For a sure loss of $740.

The expected loss for Option 1 is simply $740 because there is no uncertainty or probability involved.

For a 25% chance to lose nothing, and a 75% chance of losing $1000.

To calculate the expected loss for Option 2, we multiply the probabilities by the corresponding losses and sum them up:

Expected loss for Option 2 = (0.25 × $0) + (0.75 × $1000) = $0 + $750 = $750

Comparing the expected losses of both options, we find that:

Expected loss for Option 1 = $740

The fractions should be placed in the following order: 5/6 > 7/9 > 7/18

To arrange the fractions 7/18, 5/6, and 7/9 from greatest to smallest, we need to compare their values. One way to do this is to convert all the fractions to have the same denominator, which in this case is 54. To do this, we can multiply the numerator and denominator of each fraction by the appropriate factor to get a common denominator of 54:

7/18 = (7 x 3) / (18 x 3) = 21/54

5/6 = (5 x 9) / (6 x 9) = 45/54

7/9 = (7 x 6) / (9 x 6) = 42/54

Now we can compare these fractions:

45/54 > 42/54 > 21/54

So, the fractions in order from greatest to smallest are 5/6, 7/9, and 7/18. Therefore, the correct arrangement of the fractions is:

The regular expression is ^(a(aa)*b)$.

To create a regular expression for the language L = {w = {a,b}* | w has an odd number of 'a's and ends with 'b'}, we can use the following expression:

^(b|(a(aa)*b))$

Breaking it down:

^ indicates the start of the string.

(b|(a(aa)*b)) matches either 'b' or a sequence of 'a's followed by an odd number of 'a's and 'b'.

(aa)* matches zero or more pairs of 'a's.

$ indicates the end of the string.

This regular expression ensures that the string starts with 'b' or a sequence of 'a's, followed by an odd number of 'a's, and ends with 'b'. Any additional characters or sequences in between are not allowed.

For the given variables: (a) S: Monthly sales, A: advertising budget, P: Skates price. (b) S = k * (A/P) (c) variation constant = 8 (d) 14,000 rollerblades.

(a) Let S be the monthly sales (pair of rollerblades), A be the advertising budget (in dollars), and P be the price of the skates (in dollars) for the variables.

(b) Based on the information given, we can write the equation for variation as:

S = k * (A/P), where k is the constant of variation.

(c) To find the constant of variation, plug the specified values ​​of monthly sales, advertising budget, and price into the equation and solve for k.

Using values ​​of S = 12,000, A = $60,000, and P = $40:

12,000 = k * (60,000/40)

12,000 = 1,500,000

k = 12,000/1,500

k = 8

Therefore, the variation constant is 8.

(d) To answer the problem equation, we need to find the new monthly income when the advertising budget increases to $70,000. Substituting the new value A = $70,000 into the variational equation with the variational constant k = 8 and the original price P = $40 yields:

S = 8 * (70,000/40)

S = 8 * 1,750

S=14,000
