Definition of a derivative (limit of the difference quotient)
Answers
The derivative of a function f(x) at a point x = a is defined as the limit of the difference quotient as h approaches zero:
f'(a) = lim (h → 0) [f(a + h) - f(a)] / h
What is derivative?
The derivative of a function in calculus measures the function's sensitivity to changes in its input variable. Specifically, at a particular point, it represents the function's rate of change with respect to its input variable at that moment.
The derivative of a function f(x) at a point x = a is defined as the limit of the difference quotient as h approaches zero:
f'(a) = lim (h → 0) [f(a + h) - f(a)] / h
This limit represents the instantaneous rate of change or slope of the function at the point x = a. The difference quotient is the change in the function value divided by the change in the input variable (or the distance between two points on the graph of the function).
The derivative is a fundamental concept in calculus, and it has many applications in various fields of science, engineering, and economics. It allows us to calculate important quantities such as velocity, acceleration, and marginal cost, and it is used to optimize functions and solve many real-world problems.

Your school is raising money for a non-profit organization. The local chapter of the non-profit organization keeps 80% of the money raised, and 20% goes to the national chapter of the non-profit organization . Four of your friends each donate the same amount. The total money you raise for the local chapter of the non-profit organization is $51.20. How much does each friend donate?
Answers
Answer:
The amount of money donated by each friend is $16
Step-by-step explanation:
The given parameters are;
The percentage of the money raised that is kept with the local chapter = 80%
The percentage of the money raised that goes to the national chapter = 20%
The amount of money donated by each of the four friends = Equal amount each
The total amount of the money raised for the local chapter of the non-profit = $51.20
Let x represent the amount of money donated by each of the four friends
Therefore, we have;
80% of 4 × x = 51.20, which gives;
80/100 × 4 × x = 51.20
0.8 × 4 × x = 51.20
x = 51.20/(0.8 × 4) = 16
The amount of money donated by each friend = x = $16.
Answer!
A car travels from A to B at a speed of 30 mph then returns, using the same road, from B to A at a speed of 65 mph. What is the average speed for the round trip?
Answers
Average with respect to what? If we take the time-weighted average, the two legs of the trip will be weighted differently (the leg from A to B taking 60/40 = 3/2 times as long as the leg from B to A), and we will get an average of 48 MPH.
But the time-weighted average is not the only average we can consider. We could also consider the distance-weighted average (which might be useful if we were considering, say, the wear on the road caused by such travel); then the two legs would be weighted equally and the average would be 50 MPH.
Often, when people speak about average speed, it's the former of these notions which is implicitly meant (since speed itself is distance over time, we have the nice property that the time-weighted average of speeds will always be the total distance over the total time), but the latter is a perfectly legitimate notion as well. Averages are always averages with respect to some weighting, and different weightings will give different averages.
Answer:
41 mphStep-by-step explanation:
s₁ = s₂ = x {the distance from A to B}
s = s₁ + s₂ = x + x = 2x {the distance of the round trip}
t = t₁ + t₂ {the time of the round trip}
v₁ = 30 mph
v₂ = 65 mph
t₁ = s₁/v₁ = x/30 h {the time of trip from A to B}
t₂ = s₂/v₂ = x/65 h {the time of trip from B to A}
The average speed:
\(v=\dfrac st=\dfrac{2x}{\frac x{30}+\frac x {65}}=\dfrac{2x}{x(\frac 1{30}+\frac1 {65})}=\dfrac{2}{\frac{13}{390}+\frac6{390}}=2\cdot\frac{390}{19}=41.05263...\approx41\)

$\triangle DEF$ is the medial triangle of $\triangle ABC$ and $\triangle XYZ$ is the medial triangle of $\triangle DEF.$ If the perimeter of $\triangle XYZ$ is $5$, what is the perimeter of $\triangle ABC
Answers
A medial triangle is made from the midlines of the larger triangle, and its
length is half the length of the third side of the triangle.
The perimeter of ΔABC is 20Reasons:
The medial triangle of triangle ΔABC is triangle ΔDEF
The medial triangle of ΔDEF is ΔXYZ
The perimeter of ΔXYZ = 5
By the midpoint theorem, we have;
The lengths of the sides of ΔDEF = 0.5 × The lengths of the sides of ΔABC
∴ The perimeter of ΔDEF = 0.5 × The perimeter of ΔABC
Which gives;
The perimeter of ΔABC = 2 × The perimeter of ΔDEF
Similarly, between ΔXYZ and ΔDEF, we have;
The perimeter of ΔDEF = 2 × The perimeter of ΔXYZ
∴ The perimeter of ΔDEF = 2 × 5 = 10
Therefore;
The perimeter of ΔABC = 2 × 10 = 20
The perimeter of ΔABC = 20

A researcher has conducted a survey using a simple random sample of 50 registered voters to create a confidence interval to estimate the proportion of registered voters favoring the election of a certain candidate for mayor. Assume that the sample proportion who will vote for the candidate in question does not change.
The effect on the width of the confidence interval if the researcher were to survey a random sample of 200, rather than 50, registered voters is a decrease in the width of the confidence interval.Survey using:In survey research, a sample is a subset of individuals or items from a population. A survey uses a representative sample of respondents chosen from a population to infer statistically valid conclusions about the whole population. Researchers use sampling to minimize the costs of collecting data while still maintaining its accuracy. Since it is not usually feasible to survey the entire population, the goal of survey sampling is to select a representative sample that can provide reliable data about the target population with less expense, less time, and less manpower.
A confidence interval is a range of values for a parameter that is determined by the interval estimation technique. The upper and lower bounds of the interval are the point estimates of the confidence interval's unknown population parameter.The width of a confidence interval is inversely proportional to the sample size. As the sample size increases, the width of the confidence interval decreases, while the confidence level remains the same. Conversely, as the sample size decreases, the width of the confidence interval increases, while the confidence level remains the same. So, if the researcher were to survey a random sample of 200 registered voters, the width of the confidence interval would be reduced.

In the Second Law experiment, In the Second Law experiment, the acceleration is calculated by measuring the time for the cart to move from the start point to the end point and applying the kinematics equation: s= 1/2 at 2 Explain how this equation is used to find the acceleration.
Answers
The kinematics equation s = 1/2at² can be used to determine the acceleration in the Second Law Experiment, where acceleration is calculated by measuring the time taken for the cart to move from the start point to the end point.
Let's derive how the equation is used to find the acceleration from this experiment:
Drivation of kinematics equation:
The kinematics equation is derived by integrating the acceleration function twice with respect to time (t).
Acceleration, a = d²s/dt², where s is displacement, and d²s is the second derivative of displacement with respect to time.
taking integral w.r.t time twice:
∫ a dt = ∫ d²s/dt² dt integrating once gives, v = at + C₁ (where C₁ is a constant of integration)
integrating twice gives, s = 1/2at² + C₁t + C₂ (where C₂ is a constant of integration)
Thus, the kinematics equation for an object moving with constant acceleration can be represented by
s = 1/2at² + vit + s₀,
where s is the displacement, a is the acceleration, t is time, vi is initial velocity, and s₀ is initial displacement.

a movie theatre models the revenue from ticket sales in one day as a function of the ticket price, p. here are two expressions defining the same revenue function. p ( 120p - 4p ) and 120p - 4p 2 according to this model, how high would the ticket price have to be for the theater to make $0 in revenue? explain your reasoning. what equation can you write to find out what ticket price(s) would allow the theater to make $600 in revenue?
Answers
The ticket prices that would allow the theater to make $600 in revenue are $120 and $13.4.
In order for the theater to make $0 in revenue, the ticket price would have to be $4. This can be determined by setting the revenue functions equal to 0 and solving for p.
For p (120p - 4p) = 0
120p - 4p = 0
4p = 120
p = $30
For 120p - 4p2 = 0
120p - 4p2 = 0
4p2 = 120p
p2 = 30p
p = $4
To find the ticket prices that would allow the theater to make $600 in revenue, we can set the revenue functions equal to 600 and solve for p.
For p (120p - 4p) = 600
120p - 4p = 600
4p = 120 + 600
p = $120
For 120p - 4p2 = 600
120p - 4p2 = 600
4p2 = 120 + 600

in a random sample of 100 ucla students, 35 have travelled outside the us. estimate the true population proportion of ucla students who travelled outside the us using a 99% confidence interval. find the most reasonable formula to find the interval.
Answers
The most reasonable formula to find the interval is
0.35 ± 2.576 (√ (0.35 × 0.65)/100).
The subset chosen from the larger set to make assumptions is known as a random sample. A range of values is a confidence interval.
According to the given problem, n =100 and x = 35
To estimate the true population of students who travelled outside the US using a 99% confidence interval:
p = x / n
= 35 / 100
p = 0.35
At 99% confidence,
α = 1 - 0.99
α = 0.01
α/2 = 0.01/2
α/2 = 0.005
∴ z(α/2) = \(z_{0.005}\) = 2.576
99% confidence interval (CI) is,
CI = p ± z(α/2) * √(p(1-p)/n)
= 0.35 ± 2.576 * \(\sqrt{\frac{0.35(1-0.35)}{100} }\)
= 0.35 ± 2.576 * \(\sqrt{\frac{0.35(0.65)}{100} }\)
= 0.35 ± 2.576 * \(\sqrt{\frac{0.2275}{100} }\)
= 0.35 ± 2.576 * \(\sqrt{0.002275}\)
= 0.35 ± 2.576 * 0.0476969600
= 0.35 ± 0.122867391
= ( 0.35 - 0.1229,0.35 + 0.1229 )
CI = ( 0.2271,0.4729 )

Thomas' Bike Shop stocks a high volume item that has a normally distributed demand during lead time. The average daily demand is 70 units, the lead time is 4 days, and the standard deviation of demand during lead time is 15.
1) How much safety stock provides a 95% service level to Thomas?
2) What should the reorder point be
Answers
The required answer is set the reorder point at approximately 304.68 units.
Explanation:-
1) To calculate the safety stock for a 95% service level, we need to find the appropriate z-value for the normal distribution. A 95% service level corresponds to a z-value of 1.645.
Safety Stock = z-value * Standard Deviation of Demand during Lead Time
Safety Stock = 1.645 * 15
Safety Stock ≈ 24.68 units
So, Thomas needs to maintain approximately 24.68 units of safety stock to provide a 95% service level.
2) To calculate the reorder point, we need to consider the average demand during lead time and the safety stock.
Reorder Point = (Average Daily Demand * Lead Time) + Safety Stock
Reorder Point = (70 units/day * 4 days) + 24.68 units
Reorder Point ≈ 280 + 24.68
Reorder Point ≈ 304.68 units
Thomas should set the reorder point at approximately 304.68 units.
