Therefore, the approximate average volume of air in the lungs during one respiratory cycle is 1.4825 liters.

To approximate the average volume of air in the lungs during one respiratory cycle, we need to find the average value of the function V(t) over the interval from 0 to 5 seconds. The average value of a function f(x) over an interval [a, b] is given by:

Average value = (1 / (b - a)) * ∫[a, b] f(x) dx

In this case, we have \(V(t) = 0.1729t + 0.1522t^2 - 0.0374t^3\), and we need to find the average value over the interval [0, 5].

Average value = (1 / (5 - 0)) * ∫[0, 5] \((0.1729t + 0.1522t^2 - 0.0374t^3) dt\)

Evaluating the integral, we get:

Average value = (1 / 5) * \([0.08645t^2 + 0.05073t^3 - 0.00935t^4]\)evaluated from 0 to 5

Average value = (1 / 5) * \([(0.08645 * (5)^2 + 0.05073 * (5)^3 - 0.00935 * (5)^4) - (0.08645 * (0)^2 + 0.05073 * (0)^3 - 0.00935 * (0)^4)]\)

Simplifying further, we have:

Average value = (1 / 5) * [1.08125 + 6.33125 - 0] = (1 / 5) * 7.4125

Answer: X= -2.1667 Y= 13

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.

The value of x from the given condition is 34. Therefore, option B is the correct answer.

Given that, m∠C = (3x + 1)° and m∠D = (2x + 9)°.

Consecutive angles lie along the transversal, both angles will always be on one side of the transversal, and they'll either both be inside the parallel lines or outside the parallel lines (interior or exterior angles, respectively). Consecutive angles are always supplementary if the transversal crosses parallel lines.

Since, consecutive angles are always supplementary, we get

(3x + 1)°+(2x + 9)° =180°

⇒ 5x+10=180

The null hypothesis is that the proportion of students who have traveled abroad is still 12%, while the alternative hypothesis is that the proportion has increased and is now greater than 12%.

The appropriate null hypothesis is that the proportion of students at UW-Platteville who have traveled abroad remains the same as before the implementation of the study abroad program. The alternative hypothesis is that the proportion of students who have traveled abroad has increased after the implementation of the program.

Mathematically:

H0: p = 0.12

Ha: p > 0.12

where p is the true proportion of students at UW-Platteville who have traveled abroad.

To test this hypothesis, we can use a one-tailed z-test for proportions. Using the given sample information, we can calculate the test statistic as:

z = (0.35 - 0.12) / sqrt((0.12 * 0.88) / 100) = 3.87

where 0.88 is the complement of 0.12, and sqrt denotes the square root. The critical value for a one-tailed test at the 0.05 level of significance is 1.645.

Since the test statistic (3.87) is greater than the critical value (1.645), we reject the null hypothesis and conclude that there is sufficient evidence at the 0.05 level to support the claim that the proportion of students who have traveled abroad has increased after the implementation of the study abroad program.

Longest object that will fit inside a cylinder will have 12.1 inches.

Lets try to determine the length of the longest object that will fit inside a cylinder with a radius of 21/4 inches and a height of 6 inches,

We will first calculate the diameter and then the diagonal of the cylinder. Afterward, we will calculate the length of the longest object that can be fitted inside the cylinder.

Calculating the diameter

The diameter of a cylinder is double the radius.

Hence, d = 2r, where d is the diameter and r is the radius.

Therefore,

d = 2(21/4)= 42/4= 10.5 inches where r =21/4

The diagonal of a cylinder can be calculated by finding the length of the diagonal of a rectangle with length equal to the height and width equal to the diameter. Since the height of the cylinder is given as 6 inches, and the diameter is 10.5 inches, we can determine the diagonal of the rectangle using the Pythagorean theorem.

Diagonal of rectangle = √(Height² + Width²)

Diagonal of rectangle = √(6² + 10.5²) = √(36 + 110.25)

= √146.25 inches ≈ 12.1 inches

Calculating the length of the longest object that can be fitted inside the cylinder-

The longest object that can be fitted inside the cylinder is the diagonal of the cylinder, which is equal to the diagonal of the rectangle

Diagonal of cylinder = diagonal of rectangle = √146.25 inches ≈ 12.1 inches

Therefore, the length of the longest object that will fit inside a cylinder that has a radius of 21/4 inches and is 6 inches high is approximately 12.1 inches.

the work required to move a 10 nC charge from infinity to point P is 4.80 x 10^-4 J.

To calculate the work required to move a charge from infinity to point P, we need to use the formula:

W = q * (ΔV)

where q is the charge being moved and ΔV is the change in electric potential energy.

To calculate the electric potential energy at point P, we need to first calculate the electric potential at point P due to each of the three charges. The electric potential at a point due to a point charge q is given by:

V = k * (q / r)

where k is Coulomb's constant, q is the charge, and r is the distance between the point charge and the point at which the potential is being calculated.

Using this formula, we can calculate the electric potential at point P due to each of the three charges:

V1 = k * (-2.0 µC) / (0.2 m) = -8.99 x 10^9 V

V2 = k * (4.0 µC) / (0.2 m) = 1.80 x 10^10 V

V3 = k * (6.0 µC) / (0.2 m) = 2.70 x 10^10 V

The total electric potential at point P is the sum of the individual potentials:

V = V1 + V2 + V3 = 4.80 x 10^10 V

The change in electric potential energy as the charge is moved from infinity to point P is:

ΔV = V - 0 = 4.80 x 10^10 V

Finally, we can calculate the work required to move the charge:

W = q * ΔV = (10 nC) * (4.80 x 10^10 V) = 4.80 x 10^-4 J

C. The rate of change is $0.10 per minute and minutes are the independent variable

D. The rate of change is $0.10 per minute and minute are the dependent variable.

The cost of making a call is the sum of the cost of connection fee which is one time fee and cost $0.25, and the cost charged for a minute which depends on the number of minute for which the call is been established. Therefore, the total cost can be written for a x minute call is,

Total Cost = $0.25 + $0.10(x)
