Kristin boards a Ferris wheel at the 3-o’clock position and rides the Ferris wheel CCW for one full rotation. The Ferris wheel has a radius of 8 meters and the center of the Ferris wheel is 12 meters above the ground. Imagine an angle with its vertex at the center of the Ferris wheel that subtends the path Kristin travels.
Answer the following questions.
a.If Kristin has traveled 4 meters along the path of the Ferris wheel then the angle has swept out _________radians. b.If Kristin has traveled 45 meters along the path of the Ferris wheel then the angle has swept out ___________radians. c. Write a formula that expresses the number of radians θ the angle has swept out in terms of the number of meters d Kristin has traveled since the ride started.

Answers

a) If Kristin has traveled 4 meters along the path of the Ferris wheel then the angle has swept out 0.5 radians.

b) If Kristin has traveled 45 meters along the path of the Ferris wheel then the angle has swept out 5.625 radians.

c) The formula that expresses the number of radians θ the angle has swept out in terms of the number of meters is θ = s / r.

a. To determine the angle in radians, we can use the arc length formula for a circle. The formula is given by θ = s / r, where θ is the angle in radians, s is the arc length, and r is the radius of the circle.

In this case, Kristin has traveled 4 meters along the path of the Ferris wheel, and the radius is 8 meters.

Thus, the angle swept out is

θ = 4 / 8 = 0.5 radians.

b. Following the same approach, if Kristin has traveled 45 meters along the path of the Ferris wheel, the angle swept out is

θ = 45 / 8 ≈ 5.625 radians.

c. The formula that expresses the number of radians θ the angle has swept out in terms of the number of meters Kristin has traveled since the ride started is given by

θ = s / r,

where θ is the angle in radians, s is the arc length traveled by Kristin, and r is the radius of the Ferris wheel.

1. what linear function, y=f(x) has f(0) = 8 and f(7) = 14 ?

Answers

A linear function is a mathematical function that can be represented by a straight line when graphed on a Cartesian coordinate system. It is also known as a first-degree polynomial because the highest exponent of the variable is 1. The general form of a linear function is: f(x) = mx + b

To find a linear function given two points on the line, you need to use the point-slope formula.

The formula is `y - y1 = m(x - x1)`, where `(x1, y1)` is a point on the line and `m` is the slope of the line.

Given that f(0) = 8 and f(7) = 14, we can find the slope of the line:$$\frac{f(7) - f(0)}{7 - 0} = \frac{14 - 8}{7} = \frac{6}{7}$$Now, we can use the point-slope formula with the point `(0, 8)` and the slope `6/7`:$$y - 8 = \frac{6}{7}(x - 0)$$

Simplifying this equation, we get:$$y - 8 = \frac{6}{7}x$$$$y = \frac{6}{7}x + 8$$

Therefore, the linear function with `f(0) = 8` and `f(7) = 14` is `y = (6/7)x + 8`.

A linear function, y = f(x) that has f(0) = 8 and f(7) = 14 is given by: f(x) = mx + b, Where m represents the slope of the line and b represents the y-intercept. The equation of the linear function is: y = f(x) = (6/7)x + 8.

To find the slope of the line, we use the formula:

m = (y₂ - y₁) / (x₂ - x₁), where (x₁, y₁) = (0, 8) and (x₂, y₂) = (7, 14).

Substituting into the formula:

m = (14 - 8) / (7 - 0)

m = 6 / 7

Therefore, the equation of the line is given by: f(x) = (6/7)x + b.

To find the value of b, we use the fact that f(0) = 8.

Substituting into the equation, we get: 8 = (6/7)(0) + b.

Simplifying, we get: b = 8.

Therefore, the equation of the linear function is: y = f(x) = (6/7)x + 8.

b. V = 1272.3 cm^(3)
c. V = 1908.5 cm^(3)
d. V = 1424.1 cm^(3)

Answers

The volume of a cone with diameter 18 cm and height 15 cm is b. V = 1272.3 cm^(3).

To calculate the volume of a cone, we use the formula:

V = (1/3) * π * r^2 * h

where V is the volume, π is the mathematical constant approximately equal to 3.14159, r is the radius of the cone's base, and h is the height of the cone.

Given that the diameter of the cone is 18 cm, we can calculate the radius by dividing the diameter by 2:

r = 18 cm / 2 = 9 cm

Substituting the values into the volume formula:

V = (1/3) * π * 9^2 * 15

Calculating:

V ≈ 1272.3 cm^3

Therefore, the volume of the cone is approximately 1272.3 cm^3.

The city of İzmir is prone to three main types of natural hazards: earthquakes, winds and floods. Each of these can be modelled as a Poisson process. The mean annual occurrence rates for earthquakes and floods are 0.1 and 0.25 damaging events, respectively. The wind is considered as a hazard when the speed exceeds 40m/s. The probability distribution for the annual wind speed is known to be lognormal with a median of 30m/s and a coefficient of variation 0.2. All the three hazardous events occur independently of each other, and each can cause damages with an approximate cost of 2M TL. For proper budgeting, the municipality of İzmir needs to calculate the expected monetary loss from natural hazards, and approximately estimates the loss as a product of the number of hazardous events and the related cost. Based on this data, find out: a) What is the return period of a hazardous wind? b) What is the probability that more than 3 hazardous events in total can happen within a year? c) What is the probability that no hazardous events can happen within 5 years? d) Provide estimates for the mean and standard deviation of expected annual monetary losses so as to have an idea about how much budget the municipality should allocate for natural hazards.

Answers

The return period of a hazardous wind can be calculated by finding the inverse of its cumulative distribution function (CDF) at a certain threshold value.

a) To determine the return period of a hazardous wind, we need to find the threshold wind speed that corresponds to a specific return period. Since the wind speed follows a lognormal distribution with a known median and coefficient of variation, we can calculate the corresponding quantile using the inverse of the lognormal CDF.

b) The probability of more than 3 hazardous events in the total happening within a year can be calculated using the Poisson distribution. We sum the probabilities of having 4, 5, 6, and so on hazardous events in a year.

c) The probability of no hazardous events happening within 5 years can also be calculated using the Poisson distribution. We calculate the probability of zero hazardous events in one year and then raise it to the power of 5.

d) To estimate the mean and standard deviation of expected annual monetary losses, we multiply the mean number of hazardous events for each type by the cost per event. Since the three hazardous events occur independently, we can sum the expected losses for each type.

The standard deviation of the expected losses can be calculated using the properties of independent random variables. By calculating the mean and standard deviation of expected annual monetary losses, the municipality can have an idea of the budget allocation required to mitigate the impact of natural hazards in Izmir.

Answers

It should be noted that the probability of obtaining a sample mean of 39.1 hours or less is quite low (0.035), it can be considered unusually short.

How to calculate the probability

The mean of the sampling distribution of the sample mean, μ, is equal to the population mean, which is μ = 40 hours.

The standard deviation of the sampling distribution is σ(μ) = 5 / √100

= 5 / 10

= 0.5 hours.

Plugging in the values, we get (40.6 - 40) / 0.5

= 0.6 / 0.5

= 1.2.

Looking up the z-score of 1.2 in the standard normal distribution table (or using a calculator), we find that the probability is approximately 0.884.

Now, let's calculate P(≤39.1). Similarly, we calculate the z-score as (x - μ) / σ(μ), where x = 39.1 hours. Plugging in the values, we get (39.1 - 40) / 0.5

= -0.9 / 0.5

= -1.8.

Using the z-score table or a calculator, we find that the probability is approximately 0.035.

This probability represents the area under the curve to the left of -1.8, which is a left-tailed probability.

Answers

The body's position at time t is given by the equation s(t) = [tex]4.9t^2 + 15t + 20[/tex].

To find the body's position at time t,

we need to integrate the velocity function with respect to time and apply the initial condition.

Given:

v = 9.8t + 15

s(0) = 20

First, integrate the velocity function with respect to time to obtain the position function:

∫v dt = ∫(9.8t + 15) dt

s(t) = [tex]4.9t^2 + 15t + C[/tex]

Next, we apply the initial condition s(0) = 20 to determine the value of the constant C:

s(0) =[tex]4.9(0)^2 + 15(0) + C[/tex]

20 = C

Now, we have the complete position function:

s(t) =[tex]4.9t^2 + 15t + 20[/tex]

In conclusion, To find the position of the body at time t,

we integrated the velocity function with respect to time,

A researcher wants to test the claim that the average lifespan for florescent lights is 1600 hours. A random sample of 100 fluorescent lights has a mean lifespan of 1580 hours, and a standard deviation of 100 hours. Is there evidence to support the claim at 5% level of significance?

Answers

Yes,  there is evidence at a 5% level of significance to support the claim that the average lifespan for fluorescent lights is not 1600 hours.

How do we calculate?

Null hypothesis: is defined as the average lifespan for fluorescent lights is 1600 hours.

Alternative hypothesis : is defined as  average lifespan for fluorescent lights is not 1600 hours.

Sample size (n) = 100

Sample mean = 1580 hours

Sample standard deviation (s) = 100 hour

t = (Sample mean - μ) / (s / √n)

μ =  hypothesized population mean

s=  sample standard deviation

t = (1580 - 1600) / (100 / √100)

t = -20 / (100 / 10)

t = -20 / 10

t = -2

The significance level of 0.05 will be divided by 2 to get an alpha level of 0.025.

We make use of a  t-distribution table to look up the critical t-value in the with degrees of freedom equal to n-1 = 99.

The critical t-value is  1.984 for a significance level of 0.025 and degrees of freedom = 99.

In conclusion,  we have evidence to reject the null hypothesis because the absolute value of the test statistic is greater than the critical t-value.
