Answer:

169.56 inches farther

Step-by-step explanation:

Eric: 30 x 3.14 = 94.2 inch per revolution

Maggie: 24 x 3.14 + 75.36 inch per revolution

94.2 x 9 = 847.8 inches

75.35 x 9 = 678.24 inches

847.8 - 678.24 = 169.56 inches farther

The z-coordinate of the mass center of the homogeneous paraboloid of revolution shown is (12/5) units.

The determination of the z-coordinate of the mass center of the homogeneous paraboloid of revolution requires a long answer.

Firstly, we need to define the mass density of the paraboloid. Since it is a homogeneous object, its mass density is constant throughout its volume.

Let us denote this density as ρ.

Next, we need to find the volume of the paraboloid.

The volume of a paraboloid of revolution with a height h and a base radius r is given by V = (π/2) * r^2 * h/3.

In this case, the height of the paraboloid is 4 units and the radius of the base is 2 units. Thus, the volume of the paraboloid is:
V = (π/2) * (2)^2 * 4/3 = (8π/3) units^3

Now, we can find the mass of the paraboloid by multiplying its volume by its density:
M = ρ * V = ρ * (8π/3) units^3

The next step is to find the x and y coordinates of the mass center of the paraboloid.

We can do this by using double integrals:
x = (1/M) * ∬(paraboloid) x * ρ * dV
y = (1/M) * ∬(paraboloid) y * ρ * dV

Since the paraboloid is symmetric about the z-axis, we know that its mass center will lie on this axis, and thus, its x and y coordinates will be zero.

Finally, we need to find the z-coordinate of the mass center. We can do this by using the same double integral, but this time we integrate over the z-axis:
z = (1/M) * ∬(paraboloid) z * ρ * dV

To set up the double integral, we can use cylindrical coordinates, with ρ ranging from 0 to 2 and θ ranging from 0 to 2π.

The z-coordinate of any point on the paraboloid is given by z = (1/16) * (x^2 + y^2), so we can substitute this into the double integral:
z = (1/M) * ∫(0 to 2π) ∫(0 to 2) ∫(0 to (1/16)*(ρ^2)) ρ * z * ρ * ρ * dρ dθ dz

After evaluating this integral, we get:
z = (3/5) * h = (12/5) units

Therefore, the z-coordinate of the mass center of the homogeneous paraboloid of revolution shown is (12/5) units.

The expressions ((p ∨ r) ∧ (q ∨ ¬r)) and (p ∨ q) are logically equivalent.

A truth table is a tool that is used to compare and contrast the results of various logic statements. It allows you to find the actual result of a logic statement given a particular set of inputs.

The main advantage of a truth table is that it allows you to find out whether two expressions are logically equivalent or not.

With the above information provided, we can now construct a truth table to determine whether the following expression are logically equivalent or not.

Let's start by constructing the truth table:

Truth table

pqr¬rq ∨ rp ∨ rq ∨ ¬r(p ∨ r) ∧ (q ∨ ¬r)(p ∨ r) ∧ (q ∨ ¬r)

⇔ p ∨ qq ∨ ¬rq ∨ qq ∨ ¬rp ∨ ¬r

TTFTRTTFTTFFFTTTTTFFFTFTFFTTFFTFFTT

As you can see from the truth table, the last two columns are identical.

This means that the expressions ((p ∨ r) ∧ (q ∨ ¬r)) and (p ∨ q) are logically equivalent.

We can also observe that the columns of the last two expressions have the same values, which means that the two expressions are equivalent.

Answer:

Step-by-step explanation:

Let's assume the initial number of men at the exhibition is 10x, and the initial number of women is 3x.

After 110 men left, the number of men remaining is 10x - 110.

The total number of people remaining is (10x - 110) + (3x) = 13x - 110.

According to the given information, the number of men remaining (10x - 110) is 5/12 of the total number of people remaining (13x - 110). We can write this as an equation:

10x - 110 = (5/12)(13x - 110)

To solve this equation, we can start by simplifying both sides:

10x - 110 = (65/12)x - (55/6)

To get rid of the fractions, we can multiply both sides of the equation by 12:

12(10x - 110) = 65x - 110(2)

120x - 1320 = 65x - 220

Next, we can bring the x terms to one side and the constant terms to the other side:

120x - 65x = 1320 - 220

55x = 1100

Dividing both sides by 55, we find:

x = 20

Now, we can substitute the value of x back into the initial expressions to find the number of men and women:

Number of men = 10x = 10(20) = 200

Number of women = 3x = 3(20) = 60

Therefore, there were 60 women at the exhibition

The sentence "The airplane takes off smoothly" can be interpreted in terms of the function f, its derivative f', and its second derivative f". In this interpretation, f represents the altitude of the plane, which is a function of time.

The sentence implies that the function f is continuous and differentiable, indicating a smooth takeoff.

The derivative f' of the function f represents the rate of change of the altitude, or the velocity of the airplane. If the airplane takes off smoothly, it suggests that the derivative f' is positive and increasing, indicating that the altitude is increasing steadily.

The second derivative f" of the function f represents the rate of change of the velocity, or the acceleration of the airplane. If the airplane takes off smoothly, it implies that the second derivative f" is either positive or close to zero, indicating a gradual or smooth change in velocity. A positive second derivative suggests an increasing acceleration, while a value close to zero suggests a constant or negligible acceleration during takeoff.

Overall, the interpretation of the sentence in terms of f, f', and f" indicates a continuous, differentiable function with a positive and increasing derivative and a relatively constant or slowly changing second derivative, representing a smooth takeoff of the airplane.

The optimal size of the production run is 1994.

Explanation:

Part A: The formula for the optimal production run size is:

EOQ = √(2DS / H)

where D is Annual demand, S is Setup cost per order, H is Holding cost per unit per year

Substituting the values given in the question:

EOQ = √(2 × 8000 × 100 / 10)

EOQ = √(16 × 10^6 / 10)

EOQ = √(1600000)

EOQ = 1264.911 rounding up to 1265

Part B: The number of production runs per year is given by:

Number of production runs = Annual demand / EOQ

Number of production runs = 8000 / 1265

Number of production runs = 6.313 round up to 7

Part C: The length of the production run is given by:

Production run length = EOQ / Daily demand

Production run length = 1265 / 20

Production run length = 63.25 round up to 64 days

Part D: The total cost of inventory per year is given by:

Total inventory cost = [(EOQ / 2) × H × (Annual demand / EOQ)] + [(Annual demand / EOQ) × S]

Total inventory cost = [(1265 / 2) × 10 × (8000 / 1265)] + [(8000 / 1265) × 100]

Total inventory cost = 632.50 + 631.10

Total inventory cost = 1263.60

The height of the plane is about 3855 feet and the distance from the nearer end of the runway is about 13580 feet.

To find out the height of the plane and the distance of it from the nearer end of the runway, we have to use trigonometry.

Let's start by finding the height of the plane, h.

Using the angle of depression of 12.5 degrees, we can write this equation:

tan 12.5 = h/d

Where d is the distance from the nearer end of the runway. If we cross-multiply, we get:

d = h/tan 12.5

We can use the equation from the other angle of depression to eliminate the distance,

d.tan 17.0 = h/(d + 10,000)

By substituting the previous equation in for d, we get:

tan 17.0 = h/(h/tan 12.5 + 10,000)

Simplifying: tan 17.0 = h(tan 12.5)/(h/tan 12.5 + 10,000)

Multiplying both sides by h/tan 12.5 + 10,000:

tan 17.0 (h/tan 12.5 + 10,000) = h tan 12.5

Expanding the left side: distributed = h + 10,000 tan 17.0 tan 12.5

Simplifying and isolating h: h = 10,000 tan 17.0 tan 12.5/(tan 12.5 - tan 17.0) ≈ 3855 ft

Therefore, the height of the plane is about 3855 feet. To find the distance from the nearer end of the runway, we use the previous equation:d = h/tan 12.5 ≈ 13580 ft

Therefore, the distance from the nearer end of the runway is about 13580 feet.

The linear velocity of the rotor blades of the helicopter is approximately 757.67 ft/min.

To calculate the linear velocity of the rotor blades of a helicopter, we can use the formula:

Linear Velocity = (2 * π * r * rpm) / 60

where r is the length of the rotor blades and rpm is the rotations per minute.

Given that the length of the rotor blades is 19 ft and the rotation rate is 190 rpm, we can substitute these values into the formula:

Linear Velocity = (2 * π * 19 * 190) / 60

Simplifying this expression:

Linear Velocity = (2 * 3.1416 * 19 * 190) / 60

Linear Velocity ≈ 2 * 3.1416 * 19 * 3.1667

Linear Velocity ≈ 757.67 ft/min
