exercise 5.3.1. recall from exercise 4.4.9 that a function f : a → r is lipschitz on a if there exists an m > 0 such that ∣∣∣∣ f(x) − f(y) x − y ∣∣∣∣ ≤ m for all x ?
If f is differentiable on a closed interval [a,b] and if f' is continuous on the interval [a,b], Then f is Lipschitz on [a,b].
What is a Lipschitz function?
If a neighborhood U of x exists for any x in X such that f restricted to U is Lipschitz continuous, then the function is said to be locally Lipschitz continuous. Alternatively, f is locally Lipschitz if and only if it is Lipschitz continuous on each compact subset of X if X is a locally compact metric space.
Now,
Assume that f can be differentiated and that f' is continuous on [a,b]. Therefore, f' is bounded since [a,b] is compact. In other words, for all x [a,b] there exists M > 0 such that: |f'(x)| ≤ M.The Mean Value Theorem therefore ensures that there exists c between x and y such that: [tex]|\frac{f(x)-f(y)}{x-y}|=|f'(c)|\leq M[/tex], for each x,y ∈[a,b].Given that x and y were chosen at random, we can infer that f is Lipschitz on [a,b] since the inequality: [tex]|\frac{f(x)-f(y)}{x-y}|\leq M[/tex], holds for all x,y ∈ [a,b].Hence, If f is differentiable on a closed interval [a,b] and if f' is continuous on the interval [a,b], Then f is Lipschitz on [a,b].

Tony's Carnival charges $25 to enter the park and $4.50 per ride. Ride Palace charges $18 to enter the park and $5 per ride. How many rides do you need to ride for the cost of each park to be the same?
Answer:
14
Step-by-step explanation:
Let x = number of rides.
Tony's cost: 4.5x + 25
Ride's cost: 5x + 18
Set the prices equal and solve for x.
5x + 18 = 4.5x + 25
Subtract 4.5x from both sides.
0.5x + 18 = 25
Subtract 18 from both sides.
0.5x = 7
Multiply both sides by 2.

Relationships that have a uniform or constant rate are said to be proportional relationships. Because it does not employ a uniform rate, the price of food does not follow a proportional connection.
The missing table looks like this:
Bag cost
0 0
5 17.5
30 89
First, we calculate the slope (m) of the table using:
(x₁ y₁) = (0,0)
(x₂ y₂) = (5,17.5)
m₁=(y₂-y₁)/(x₂ -x₁)
m₁=(17.5-0)/(5-0)
m₁=3.5
The slope for the following points
(x₁ y₁) = (0,0)
(x₂ y₂) = (30,89)
m₂=(y₂-y₁)/(x₂ -x₁)
m₂=(89-0)/(30-0)
m₂=2.97
3.5 ≠2.97
Hence, the cost of food is not a proportional relationship because it does not use a uniform rate.

A truck can be rented from Company A for $130 a day plus $0.30 per mile. Company B charges $70 a day plus $0.60 per mile to rent the same truck. Find the number of miles in a day at which the rental costs for Company A and Company B are the same.
Considering the definition of an equation and the way to solve it, the number of miles in a day at which the rental costs for Company A and Company B are the same is 200.
Definition of equationAn equation is the equality existing between two algebraic expressions connected through the equals sign in which one or more unknown values, called unknowns, appear.
The members of an equation are each of the expressions that appear on both sides of the equal sign.
The solution of a equation means determining the value that satisfies it. To solve an equation, keep in mind:
When a value that is adding, when passing to the other member of the equation, it will subtract.If a value you are subtracting goes to the other side of the equation by adding.When a value you are dividing goes to another side of the equation, it will multiply whatever is on the other side.If a value is multiplying it passes to the other side of the equation, it will pass by dividing everything on the other side.Number of miles in this caseFirst, you define the variable "m" as the number of miles rented from a truck to a company in a day. You know that:
A truck can be rented from Company A for $130 a day plus $0.30 per mile. Company B charges $70 a day plus $0.60 per mile to rent the same truck.So the price of each company is:
Price of company A=130 + 0.30mPrice of company B=70 + 0.60mIf the rental costs for Company A and Company B are the same, the equation in this case is:
Price of company A= Price of company B
130 + 0.30m= 70 + 0.60m
Solving:
130 - 70= 0.60m - 0.30m
60= 0.30m
60÷0.30= m
200= m
In summary, the number of miles in a day at which the rental costs for Company A and Company B are the same is 200.

13. Measuring bone density Individuals with low bone
density have a high risk of broken bones (fractures).
Physicians who are concerned about low bone density
(osteoporosis) in patients can refer them for special-
ized testing. Currently, the most common method for
testing bone density is dual-energy X-ray absorptiom-
etry (DEXA). A patient who undergoes a DEXA test
usually gets bone density results in grams per square
centimeter (g/cm²) and in standardized units.
7.
Judy, who is 25 years old, has her bone density
measured using DEXA. Her results indicate a bone
density in the hip of 948 g/cm² and a standardized
score of z = -1.45. In the reference population of
25-year-olet women like Judy, the mean bone density
in the hip is 956 g/cm².6
(b) Use the information provided to calculate the standard
deviation of bone density in the reference population.
Using the normal distribution, the standard deviation of bone density in the reference population is of 5.52 g/cm².
Normal Probability DistributionThe z-score of a measure X of a normally distributed variable with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex] is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
The z-score measures how many standard deviations the measure is above or below the mean. Looking at the z-score table, the p-value associated with this z-score is found, which is the percentile of X.For this problem, the parameters are given as follows:
[tex]X = 948, z = -1.45, \mu = 956[/tex]
Hence we solve for [tex]\sigma[/tex] to find the z-score as follows:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]-1.45 = \frac{948 - 956}{\sigma}[/tex]
[tex]-1.45\sigma = -8[/tex]
[tex]\sigma = \frac{8}{1.45}[/tex]
[tex]\sigma = 5.52[/tex]

In a 5000 m race on a 400 m track, each athlete must run 12 ½ laps. kara runs the race at a constant pace and finishes in 17.5 min, while hannah runs at a faster pace and finishes 15.3 min. in fact, hannah ran fast enough that she passed kara during the race. how many laps had hannah run when she caught and passed kara?
Hannah had run 6 complete laps and is running the 7th lap when she surpasses the athlete Kara.
Who is an athlete?An athlete (sometimes known as a sportsman or sportswoman) is a person who participates in one or more sports that require physical stamina, speed, or strength.
Professional and amateur athletes both exist. The majority of elite athletes have extremely well-developed bodies because to rigorous physical training, stringent exercise, and a tight food regimen.
Isotonic exercisers had a greater mean left ventricular end-diastolic capacity and are less prone to experience depression. Athletes are far more prone than the general public to go to massage parlors and pay for the services of massotherapists and masseurs due to their demanding physical activity. Athletes whose sport favors endurance over strength typically consume less calories than other athletes.
Calculations:
Total length of the race (L) = 5000 m
Time taken by Kara (tk) = 17.9 min = 1074 s
Kara's speed (vk) = L/tk = 5000/1074 m/s
Time taken by Hannah (th) = 15.3 min = 918 s
Hannah's speed (vh) = L/th = 5000/918 m/s
Let the number of laps Hannah had run when she passes Kara be n
Distance travelled by Hannah in this time = n*400 = 400n meters
Time taken by Hannah to run n laps = 400n/(5000/918)=367200n/5000=73.44n
Distance travelled by Kara in this time = (n-1)*400 = 400n - 400 meters
Time taken by Kara to run (n-1) laps = (400n-400)/(5000*1074)=(429600n-429600)/5000=85.92n-85.92
= 85.92n - 85.92 = 73.44n
