The depth of water changes at a rate of -13/72π feet per minute when the water is 2 feet high.

To begin, we must use the formula for the volume of a cone, which is given as:

V = 1/3πr2hwhere V represents the volume, π represents the constant pi, r represents the radius, and h represents the height.

Substituting the given values into the formula, we get:

V = 1/3π (6 ft)2(14 ft)V = 1/3π (36 ft2) (14 ft)V = 1/3π (504 ft3)V = 168π ft^3

Now, we must determine the rate at which water is leaking. It is given that the cone leaks water at a rate of 13 cubic feet per minute. This implies that the volume of the water reduces by 13 cubic feet every minute. Therefore, the rate of change of the volume of water is -13 cubic feet per minute. Here, the negative sign indicates a decrease in the volume of water.

Now, we must find how fast the depth of water changes when the water is 2 feet high. Let d represent the depth of water. Then, the volume of water is given as:

V = 1/3πr^2d

We know that when d = 2 ft, V = 1/3π(6 ft)2(2 ft)

V = 8π ft^3

Now, we must determine how fast the volume of water is changing with respect to time when d = 2 ft. We differentiate the expression for V with respect to time to get:

dV/dt = (d/dt)[1/3πr2d]

dV/dt = 1/3πr^2(d/dt)[d]

dV/dt = 1/3πr^2(d/dt)[2]

dV/dt = 2/3πr^2

The rate of change of the volume of water with respect to time is given as -13 cubic feet per minute. Therefore, substituting this into the expression above, we get:

-13 = 2/3π(6 ft)2(d/dt)

When we simplify the above equation, we get:

d/dt = -13/72π

Therefore, when the water is 2 feet high, the depth of the water changes at a rate of -13/72π feet per minute.

Let's start by finding the current monthly revenue of the airline for the given number of passengers and ticket price:

Monthly revenue = number of passengers x ticket price

Monthly revenue = 9000 x $30

Monthly revenue = $270,000

Now, let's find the number of passengers for each $1 increase in the ticket price:

Number of passengers lost = 50

So, for a ticket price increase of $x, the number of passengers will be:

Number of passengers = 9000 - 50x

The ticket price will then be $30 + $x, and the revenue will be:

Revenue = (9000 - 50x) x ($30 + $x)

Revenue = 270,000 - 1500x + 30x + x^2

Revenue = x^2 - 1470x + 270,000

To find the ticket price that will maximize the revenue, we need to find the vertex of the parabola given by the revenue equation. The x-coordinate of the vertex is:

x = -b/2a

Where a = 1, b = -1470, and c = 270,000.

x = -(-1470)/2(1)

x = 1470/2

x = 735

So, the ticket price that will maximize the revenue is $30 + $735 = $765. The maximum monthly revenue is then:

Revenue = (9000 - 50(735)) x ($30 + $735)

Revenue = 105 x $765

Revenue = $80,325

Therefore, the ticket price that will maximize the airline's monthly revenue for the route is $765, and the maximum monthly revenue is $80,325.

What is proportionality?

Proportionality is a mathematical relationship between two variables, where one variable is a constant multiple of the other. In other words, two quantities are proportional if they maintain a constant ratio to each other, meaning that as one quantity increases or decreases, the other quantity changes in the same proportion.

We are given that the time it takes to print a batch of newspapers, m, is inversely proportional to the number of printers used, n, and the equation of proportionality is:

m = k/n

where k is a constant of proportionality. We are also given that when k = 100, the equation is satisfied. So we can substitute k = 100 into the equation to get:

m = 100/n

To find the time it will take to print a batch of newspapers if 20 printers are used, we can substitute n = 20 into the equation:

m = 100/20 = 5

According to the student question, the sampling distribution of the proportion of people who respond "yes" in the samples of 4 individuals is binomial because the number of people who respond "yes" has binomial distribution. The correct answer is A.

The sampling distribution of the proportion of people who respond "yes" in the samples of 4 individuals is binomial because the sample size is sufficiently small and each person's response is independent of the others.

Binomial distribution is used to model the number of successes in a fixed number of independent trials, where the probability of success is constant for each trial. In this case, the proportion of people who respond "yes" is the number of successes out of the total number of trials (i.e., 4 people).

Moreover, the responses of each individual are independent of each other, meaning that the probability of one person answering "yes" does not affect the probability of another person answering "yes."  The correct answer is A.

The value of k that makes the three points lie on the same line is -8.

To determine the value of k such that the given points lie on the same line, we can use the slope-intercept form of the equation of a line, which is:

y = mx + b

where m is the slope of the line, and b is the y-intercept.

First, we can find the slope of the line passing through the two points (0, -2) and (10, -7):

m = (y2 - y1) / (x2 - x1)

m = (-7 - (-2)) / (10 - 0)

m = -5 / 10

m = -1/2

Now, we can use the slope-intercept form with the point (0, -2) to find the value of b:

-2 = (-1/2)(0) + b

b = -2

So the equation of the line passing through the two points (0, -2) and (10, -7) is:

y = (-1/2)x - 2

To check if the point (k, 2) lies on this line, we can substitute k for x and 2 for y in the equation:

The total area of the shaded region is 67.92 sq. in.

A sector is a section of a circle that may be described using the following four criteria:

Two radii and an arc surround a section of a circle. The two sectors that make up a circle are referred to as the minor and major sectors. The main sector of the circle is the larger area, while the minor sector is the smaller area. The circle is split into two equally sized sections in the case of semicircles.

Let us suppose the central angle of the shaded portion = x.

From the given figure we observe that angle DEC = 143 degrees, and angle AEB are equal as they are vertically opposite angles.

The angle formed by the shaded regions are same as they are vertically opposite angles.

Thus,

143 + 143 + x + x = 360

286 + 2x = 360

2x = 74

x = 37

Now, the area of the sector is given as:

A = α/360 πr²

Here, r = 10.4 in.

Substituting the values:

A = (37/360)π(10.4)²

A = (0.10)(3.14)(10.4)²

A = 33.96 sq in.

There are two shaded portions thus:

The answer of the given question is , the predicted average retail price of a car in 2003 is $9860.40.and  the car will be worth $814 in the year 2010.

A regression equation is a mathematical formula that is used to describe the relationship between two or more variables. It is typically used in statistical analysis to model the relationship between a dependent variable and one or more independent variables.In simple linear regression, there is only one independent variable, and the regression equation takes the form of a straight line. In multiple regression, there are two or more independent variables, and the regression equation takes the form of a more complex mathematical function.

Using a calculator, we can input the data points into a regression equation to find the line of best fit. Using the given data, we get the regression equation:

y = -1357.4x + 18003.8

where y represents the retail price of a car and x corresponds to the year, with x = 1 representing 1998.

To predict the average retail price of a car in 2003, we need to substitute x = 6 (since 2003 corresponds to x = 6) into the regression equation:

y = -1357.4(6) + 18003.8

y = -8144.4 + 18003.8

y = 9860.4

So, the predicted average retail price of a car in 2003 is $9860.40.

To determine the year when the car will be worth $814, we need to substitute y = 814 into the regression equation and solve for x:

814 = -1357.4x + 18003.8

Simplifying, we get:

-1357.4x = -17189.8

x = 12.65

Rounding up to the nearest whole number, we get x = 13, which corresponds to the year 2010. Therefore, the car will be worth $814 in the year 2010.

What is percentage?

A percentage is a way to describe a part of a whole. such as the fraction  1/4 can be described as 0.25 which is equal to 25%.

To convert a fraction to a percentage, convert the fraction to decimal form and then multiply by 100 with the '%' symbol.

To determine if a sample size of 1,400 is adequate for estimating a proportion of 67%, we need to calculate the margin of error and compare it to the given tolerance level of 0.025.

We can use the following formula to calculate the margin of error:

E = z x √(p x (1-p)/n)

where:

Plugging in the values, we get:

E = 1.96 x √(0.67 x (1-0.67)/1400) ≈ 0.025

So, the margin of error is approximately 0.025. This means that we can expect the true proportion to be within 0.025 of the estimated proportion with 95% confidence.

Since the calculated margin of error is equal to the desired tolerance level, we can conclude that a sample size of 1,400 is adequate for estimating a proportion of 67% with the given level of confidence and tolerance. Therefore, we can be reasonably confident that our estimate of 67% is within 2.5% of the true proportion.

Therefore, the solution to the equation is q= -10. We can check our answer by plugging q= -10 back into the original equation:

[tex]\frac{4}{q}(q-10) &= 8 \\\\\\\Rightarrow \qquad \frac{4}{-10}(-10-10) &= 8 && \text{substitute }q=-10\\\\\\\Rightarrow \qquad -\frac{4}{5} \cdot (-20) &= 8 \\\\\\\Rightarrow \qquad 16 &= 8\end{align*}[/tex]

Since the last equation is false, the solution q = -10 does not satisfy the original equation. Therefore, there is no solution to the equation.
