3. let f be a differentiable function on an open interval i and assume that f has no local minima nor local maxima on i. prove that f is either increasing or decreasing on i.
Shown that if f has no local minima nor local maxima on i, then f is either increasing or decreasing on i.
Since f has no local minima nor local maxima on i, it means that for any point x in i, either f is increasing or decreasing in a small interval around x. In other words, either f'(x) > 0 or f'(x) < 0 for all x in i.
Now suppose there exist two points a and b in i such that a < b and f(a) < f(b). We want to show that f is increasing on i.
Consider the interval [a,b]. By the Mean Value Theorem, there exists a point c in (a,b) such that f'(c) = (f(b) - f(a))/(b - a). Since f(a) < f(b), we have (f(b) - f(a))/(b - a) > 0, which implies f'(c) > 0. Since f'(x) > 0 for all x in i, it follows that f is increasing on [a,c] and on [c,b]. Therefore, f is increasing on i.
A similar argument can be made if f(a) > f(b), which would imply that f is decreasing on i.

Calculate the perimeter and area of the shaded region in the drawing of two circles at right. Round to the nearest tenth. Show all work. 10 5cm 21 cm
The perimeter of the shaded region is approximately 85.67 cm The area of the shaded region is approximately 91.84 cm² (rounded to the nearest tenth).
To calculate the perimeter and area of the shaded region, we first need to find the radius of each circle.
The larger circle has a diameter of 21 cm, which means its radius is 10.5 cm (half of the diameter). The smaller circle has a diameter of 10 cm, so its radius is 5 cm.
To find the perimeter of the shaded region, we need to add the circumference of both circles and subtract the overlap (the length of the shared segment). The circumference of the larger circle is 2π(10.5) ≈ 65.97 cm, and the circumference of the smaller circle is 2π(5) ≈ 31.42 cm.
To find the length of the shared segment, we can use the Pythagorean theorem. The distance between the centers of the circles is 15 cm (the sum of the radii), so we can form a right triangle with legs of 10.5 cm and 5 cm. Using the Pythagorean theorem, we get:
c² = a² + b²
c² = 10.5² + 5²
c² ≈ 137.25
c ≈ 11.72
So the length of the shared segment is approximately 11.72 cm.
Therefore, the perimeter of the shaded region is approximately 65.97 + 31.42 - 11.72 = 85.67 cm (rounded to the nearest tenth).
To find the area of the shaded region, we need to subtract the area of the smaller circle from the area of the larger circle, and then subtract the area of the overlap (the area of the shared segment).
The area of the larger circle is π(10.5)² ≈ 346.36 cm², and the area of the smaller circle is π(5)² ≈ 78.54 cm².
To find the area of the shared segment, we can use the formula for the area of a sector of a circle:
A = (θ/360)πr²
where θ is the central angle of the sector. In this case, the sector has a central angle of 2cos⁻¹(5/10.5) ≈ 105.2°, so:
A = (105.2/360)π(10.5)²
A ≈ 91.84 cm²

Taxable income = ($38,000) * 0.20
Taxable income = ($7,600)
2019:
Taxable income = Pretax financial income * Tax rate
Taxable income = ($33,000) * 0.20
Taxable income = ($6,600)
2020:
Taxable income = Pretax financial income * Tax rate
Taxable income = $122,000 * 0.20
Taxable income = $24,400
2021:
Taxable income = Pretax financial income * Tax rate
Taxable income = $90,000 * 0.20
Taxable income = $18,000

mr. bro opened a chick-fil-a on white plains road, and ms. kramer opened a popeye’s across the street. both had to borrow money to open their fast food franchises. after 500 customers, mr. bro was still $4000 in debt. by the time he had served 3000 customers, he was ahead $1000.
after 2000 customers, ms. kramer still owed $6000 to the bank. however, after 4500 customers, she was ahead by $1500.
which restaurant would you rather own? support your answer with mathematical evidence. you must show all work and math calculations. some things we have to see in your solution:
amount each had to borrow to open their restaurant
amount of customers they needed to break even (break even means the total profit is $0)
the solution to your system of equations showing when one restaurant would produce more total income than the other
The calculations for break even point is 5000 customers, and the solution to the system of equations were shown. Mr. Bro's Chick-fil-A franchise would be more profitable as it required less initial borrowing, broke even sooner and generated more income than Ms. Kramer's Popeye's franchise.
To solve this problem, we need to set up a system of equations. Let's use "b" to represent the amount each owner had to borrow to open their restaurant, "x" to represent the number of customers, and "y" to represent the total profit.
For Mr. Bro's Chick-fil-A
After 500 customers: y = -4000
After 3000 customers: y = 1000
We can use these two equations to find the slope of the line: m = (1000 - (-4000)) / (3000 - 500) = 1.8
Using the point-slope form of a line y - (-4000) = 1.8(x - 500)
Simplifying, we get: y = 1.8x - 3400
For Ms. Kramer's Popeye's
After 2000 customers: y = -6000
After 4500 customers: y = 1500
We can use these two equations to find the slope of the line: m = (1500 - (-6000)) / (4500 - 2000) = 1.4
Using the point-slope form of a line: y - (-6000) = 1.4(x - 2000)
Simplifying, we get: y = 1.4x - 5400
Now, we can set the two equations equal to each other to find the break-even point
1.8x - 3400 = 1.4x - 5400
0.4x = 2000
x = 5000
This means that both restaurants need to serve 5000 customers to break even.
To compare the total income of the two restaurants, we can find the y-value for both equations when x = 5000
Chick-fil-A: y = 1.8(5000) - 3400 = $5,000
Popeye's: y = 1.4(5000) - 5400 = $1,000
From this analysis, it is clear that owning Chick-fil-A is more profitable than owning Popeye's.

Suzie paid a total of $324 for c tickets to a rock festival. How much does each ticket cost
If for "c" tickets, Suzie paid an amount of $324, then the cost of each ticket is represented by "324/c".
The number of tickets that Suzie bought is = c tickets, and
Let "x" be the cost of "each-ticket for "rock-festival".
The total amount spent for "c" tickets is = $324,
Therefore, we can write the cost-equation as;
⇒ c × x = 324,
To find the value of "x", we solve for it by dividing both sides of the equation by "c":
⇒ x = 324/c,
So, the cost of each ticket is $324 divided by the number of tickets "c" that Suzie bought.
Therefore, Each tickets cost is 324/c.

A particle moves with position function s=t" - 413 - 20+2 + 20t, t > 0 At what time does the particle have a velocity of 20 m/s? At what time is the acceleration 0? What is the significance of this variance?
Since t > 0, the time when the particle has a velocity of 20 m/s is approximately t ≈ 4.27 seconds.
A particle has a position function s(t) = t^3 - 4t^2 - 20t + 2 + 20t, t > 0. To find the time when the particle has a velocity of 20 m/s, we first need to find the velocity function by taking the derivative of the position function with respect to time:
v(t) = ds/dt = 3t^2 - 8t - 20.
Now set v(t) equal to 20 and solve for t:
20 = 3t^2 - 8t - 20.
40 = 3t^2 - 8t.
Now solve the quadratic equation for t:
t ≈ 4.27, -3.10.
To find the time when the acceleration is 0, we need to find the acceleration function by taking the derivative of the velocity function with respect to time:
a(t) = dv/dt = 6t - 8.
Now set a(t) equal to 0 and solve for t:
0 = 6t - 8.
t = 8/6 = 4/3.
So, the acceleration is 0 at t = 4/3 seconds.
The variance in acceleration signifies a change in the motion dynamics of the particle. When the acceleration is 0, it indicates that the particle is neither speeding up nor slowing down at that moment, resulting in a constant velocity.

The probability that Oscar gets heads and an even number is. The probability that Oscar gets tails and a prime number less than 4 is.
The probability of getting heads and an even number is 1/4, and the probability of getting tails and a prime number less than 4 is 1/6.
How to calculate coin toss probabilities?To solve this, we need to use the multiplication rule of probability, which states that the probability of two independent events occurring together is the product of their individual probabilities.
Let's first find the probability of getting heads and an even number. Since there are two equally likely outcomes when flipping a coin (heads or tails), and three equally likely outcomes when rolling a die (1, 2, 3, 4, 5, or 6), the probability of getting heads and an even number is:
P(heads and even) = P(heads) x P(even)

Next, let's find the probability of getting tails and a prime number less than 4. The prime numbers less than 4 are 2 and 3. So, the probability of getting tails and a prime number less than 4 is:
P(tails and prime) = P(tails) x P(prime)
= 1/2 x 2/6
= 1/6
Therefore, the probability that Oscar gets heads and an even number is 1/4, and the probability that Oscar gets tails and a prime number less than 4 is 1/6.

Galois Airways has flights from Hong Kong International Airport to different destinations. The following table shows the distance, `x` kilometres, between Hong Kong and the different destinations and the corresponding airfare, `y`, in Hong Kong dollars (HKD)
The cost of a flight from Hong Kong to Tokyo with Galois Airways is 1429.99 HKD.
We start by calculating the Porson's product-moment correlation coefficient between the distance and airfare data. The value of the correlation coefficient ranges from -1 to +1. A value of -1 indicates a perfect negative correlation, 0 indicates no correlation, and +1 indicates a perfect positive correlation.
In this case, the correlation coefficient between distance and airfare for Galois Airways flights is 0.948, indicates a strong positive correlation between the distance and airfare.
The regression line is expressed as:
y = a + bx
where y is the dependent variable (airfare), x is the independent variable (distance), a is the intercept (the value of y when x is zero), and b is the slope (the change in y for a one-unit change in x).
The regression equation for Galois Airways flights is:
y = 553.51 + 0.292x
Now, we can use the regression equation to estimate the cost of a flight from Hong Kong to Tokyo, which is 2900 km away.
y = 553.51 + 0.292(2900) = 1429.99 HKD
Therefore, we estimate that the cost of a flight from Hong Kong to Tokyo with Galois Airways is 1429.99 HKD.
Finally, we need to explain why it is valid to use the regression equation to estimate the airfare between Hong Kong and Tokyo. We can do this by examining the assumptions of linear regression. The two main assumptions are that there is a linear relationship between the variables, and that the residuals (the differences between the actual and predicted values) are normally distributed with constant variance.

Solve the following equation:
8 x five sixths
To solve the equation 8 x five sixths, we first convert the fraction to a decimal by dividing the numerator (5) by the denominator (6), which gives us 0.83.
We then multiply 8 by 0.83 to get the final answer of 6.64. Therefore, 8 x five sixths = 6.64.
In general, to multiply a whole number by a fraction, we can convert the fraction to a decimal and then multiply the whole number by the decimal.
Alternatively, we can convert the whole number to a fraction with a denominator of 1 and then multiply the two fractions by cross-multiplying and simplifying.
In this case, we could also write 8 as 8/1 and multiply it by 5/6 to get (8 x 5)/(1 x 6) = 40/6, which simplifies to 6 and 4/6 or 6.67 (rounded to two decimal places). However, converting the fraction to a decimal is often simpler and more practical.

Explain how the arc BX, central angle BCX, and inscribed BNX are connected. what are the relationships between them?
Answer:
See explanation.
Step-by-step explanation:
The arc BX, central angle BCX, and inscribed angle BNX are connected through the following relationships:
1. The central angle BCX subtends the arc BX. This means that the central angle is formed by two radii connecting the center of the circle to the endpoints of the arc BX.
2. The inscribed angle BNX subtends the same arc BX. This means that the inscribed angle is formed by two chords connecting a point on the circumference of the circle to the endpoints of the arc BX.
3. The relationship between the central angle BCX and the inscribed angle BNX is given by the Inscribed Angle Theorem, which states that the measure of an inscribed angle is half the measure of the central angle subtending the same arc. In other words, if θ is the measure of the central angle BCX and α is the measure of the inscribed angle BNX, then:
[tex]\alpha =\frac{1}{2}[/tex] θ

the sugar sweet company is going to transport its sugar to market. it will cost $6500 to rent trucks, and it will cost an additional $175 for each ton of sugar transported.
let c represent the total cost (in dollars), and let s represent the amount of sugar (in tons) transported. write an equation relating c to s. then use this equation to find the total cost to transport 12 tons of sugar. please give the equation used and total cost to transport 12 tons of sugar.
equation:
total cost to transport 12 tons of sugar:
The total cost to transport 12 tons of sugar is $8,600. The equation relating the total cost (c) to the amount of sugar transported (s) is: c = 175s + 6500
To find the total cost to transport 12 tons of sugar, we substitute s = 12 into the equation: c = 175(12) + 6500, c = 2100 + 6500, c = 8600
Therefore, the total cost to transport 12 tons of sugar is $8,600.
The equation shows that the total cost increases by $175 for each additional ton of sugar transported, and there is also a fixed cost of $6,500 for renting the trucks, which is added to the variable cost.
