(b) No, The branch manager's argument that dispatching buses every 0.5 minutes will reduce the average traveling time (a round trip) to 3.5 minutes is not correct.

To calculate the average time, we need to consider the time it takes for the bus to travel to the airport and back, as well as the time spent waiting for the bus.

If buses are dispatched every 3 minutes, and the average traveling time (a round trip) is 21 minutes, it means that passengers spend 18 minutes waiting for the bus (21 minutes - 3 minutes of traveling time).

If buses are dispatched every 0.5 minutes, the waiting time will be significantly reduced. However, the traveling time remains the same at 21 minutes for a round trip.

Therefore, the average traveling time will not be reduced to 3.5 minutes but will remain at 21 minutes (assuming the traveling time remains constant).

(c) The average traveling time, following the branch manager's suggestion of dispatching buses every 0.5 minutes, would still be 21 minutes.

Step-by-step explanation:

Lets assume this is a right triangle.

If you use pythagorean theorem, lets assume the tower is the longest line on the triangle.

If this is true, lets say that 9^2 (distance from end of slide to base of tower) + x^2 (length of slide) = 23^2 (height of tower)

we get the length of the slide is 21.2 meters.

This region is bounded by the lines and the non-negativity constraints (x₁ ≥ 0, x₂ ≥ 0).

Let's start by graphing the constraint inequalities:

4x₁ + x₂ ≤ 100

x₁ + x₂ ≤ 80

x₁ ≤ 40

x₁ ≥ 0, x₂ ≥ 0

First, plot the lines corresponding to the equations:

4x₁ + x₂ = 100 (let's call it line A)

x₁ + x₂ = 80 (line B)

x₁ = 40 (line C)

Now, let's shade the feasible region determined by the constraints. This region is bounded by the lines and the non-negativity constraints (x₁ ≥ 0, x₂ ≥ 0).

The feasible region will be the area of the graph that satisfies all the constraints and lies within the boundaries.

Once we have the feasible region, we can identify the optimal solution point by evaluating the objective function at each corner point of the feasible region.

Finally, we select the corner point that gives the maximum value of the objective function.

Answer:4.5

Step-by-step explanation:

Using the tangent-secant theorem, where x is the length of a tangent line segment in a circle, and we find that x is equal to 24 cm.

The given problem involves finding the value of x, which is the length of a line segment in a circle. We are given two lengths: 8 cm and 2 cm, and we need to use the tangent-secant theorem to solve for x.

The tangent secant theorem states that if a tangent and a secant line intersect at a point outside a circle, then the product of the length of the secant and its external part is equal to the square of the length of the tangent. In this case, the 8 cm line segment is the secant and the 2 cm line segment is the external part.

Using this theorem and the given values, we can set up the following equation:

2(x + 8) = \(8^2\)

Expanding the left side, we get:

2x + 16 = 64

Subtracting 16 from both sides, we get:

2x = 48

Dividing both sides by 2, we get:

x = 24

Therefore, x is equal to 24 cm.

Using the LCM,  the first customer to receive both a shopping bag and a 25% off coupon is the 45th customer.

To find the first customer who will receive both a free shopping bag and a 25% off coupon, we need to find the least common multiple (LCM) of 15 and 9, since the shopping bags are given every 15th customer and the coupons every 9th customer.

Step 1: Find the prime factors of both numbers.
15 = \(3 * 5\)
9 = \(3^2\)

Step 2: Identify the highest power of each prime factor in both numbers.
3: \(3^2\) (from 9)
5: \(5^1\) (from 15)

Step 3: Multiply the highest powers of each prime factor together to find the LCM.
LCM(15, 9) =\(3^2 * 5^1\) = \(9 * 5\) = 45

So, the first customer who will receive both a free shopping bag and a 25% off coupon is the 45th customer.

The probability that a randomly selected purchaser with an extended warranty has a basic model camera is approximately 0.0354

Denote S= Event that a purchase bought a basic camera, then P(S)=0.32

Denote D= Event that a purchase bought a deluxe camera, then

S and D are mutually exclusive.

P(D)=1-P(S)=0.68

P(W/S)=0.4

P(W/D)=4.9

We need to calculate the probability that a randomly selected purchaser who bought an extended warranty has a basic model. By notations, this is equivalent to finding P(S/W).

P(S/W)=P(W/S)*P(S)/P(W)

Since S and D are disjoint and P(S)+P(D)=1,

P(W)=P(W∩S)+P(W∩D)

P(W)=[0.4*0.32]+[4.9*0.68]

=3.61

Hence, our required probability is: P(S/W)=P(W/S)*P(S)/P(W)

\(=\frac{0.4*0.32}{3.61}\\=0.0354\)

Given the topological spaces X = {D, O, R, K} with the topology Tx and Y = {M, A, T, H} with the topology Jy, we are asked to determine whether the set E = {0, K} is open in X and open in Y.

To determine whether the set E = {0, K} is open in the topological spaces X and Y, we need to check if E belongs to the respective topologies, Tx and Ty.

In X, the topology Tx is given by: Tx = {Ø, {0}, {D, O}, {O, R}, {D, O, R}, X}. We can see that E = {0, K} is not explicitly listed in Tx. Therefore, E is not open in X since it does not belong to the topology.

In Y, the topology Ty is given by: Jy = {0, {M}, {M, A}, {M, A, T}, Y}. Again, E = {0, K} is not explicitly listed in Ty. Hence, E is not open in Y as it does not belong to the topology.

The volume of the solid generated by rotating the region between the curve y = x² and the x-axis around the x-axis over the interval [0, 1] is π/2 (or approximately 1.57) cubic units.

To find the volume of the solid generated by rotating the region between the curve y = f(x) = x² and the x-axis around the x-axis over the interval [0, 1], we can use the method of cylindrical shells.

The volume of a solid obtained by rotating a region bounded by a curve around an axis can be calculated using the formula:

V = 2π∫[a,b] x * f(x) dx

In this case, we will integrate with respect to x over the interval [0, 1] and multiply the integrand by 2π.

Let's calculate the volume:

V = 2π∫[0,1] x * (x²) dx

= 2π∫[0,1] x³ dx

To integrate x³ with respect to x, we add 1 to the exponent and divide by the new exponent:

V = 2π * [(\(x^4\))/4] evaluated from 0 to 1

= 2π * [(\(1^4\))/4 - (\(0^4\))/4]

= 2π * (1/4 - 0/4)

= π/2

The kinetic energy of the particle at any time t is 2 J. The acceleration of the particle is zero. The force acting on it at any time t is zero. The power being delivered to the particle at any time t is zero. The work done on the particle in the interval t = 0 to t = 2.00s is zero.

The given function is: x= t + 2 ...(1)

Differentiating with respect to time gives: dx/dt = v ...(2)

d²x/dt² = a ...(3)

We know that v = dx/dt

From equation (1), we have;

dx/dt = d/dt(t + 2)

dx/dt = 1

From equation (2), we have;

v = dx/dtv

= 1 m/s

(a) The kinetic energy of the particle at any time t. We know that the kinetic energy of an object of mass m moving with a velocity v is given by:

K.E = 1/2 mv²

From the above, we can see that the kinetic energy of the particle is dependent on its velocity. From equation (1), we have;

x = t + 2 ...(1)

Differentiating with respect to time gives: dx/dt = v ...(2)

Now, substituting v = 1 into equation (2), we have;

v = 1 m/s

Therefore, the kinetic energy of the particle at any time t is:

K.E = 1/2 mv²

K.E = 1/2(4)(1)²

K.E = 2 J

Therefore, the kinetic energy of the particle is 2 J.

(b) The acceleration of the particle. From equation (3), we have;

d²x/dt² = ad²x/dt²

= 0 m/s²

Therefore, the acceleration of the particle is zero.

(c) The force acting on it at time t. We know that: F = ma

From part (b), we know that the acceleration is zero, therefore, the force acting on the particle at any time t is zero.(d) The power being delivered to the particle at time t. We know that power is the rate at which work is done. Therefore, we need to find the work done on the particle in the interval t = 0 to t = 2.00s. The work done on the particle is given by:

W = FΔx

Where F is the force acting on the particle and Δx is the distance covered by the particle. From equation (1), we have;

x = t + 2

Δx = x2 - x1

Δx = (2+2) - (0+2)

Δx = 2 m

Now, F = 0.

Therefore, the work done on the particle is zero, hence the power being delivered to the particle at any time t is zero.

(e) The work done on the particle in the interval t = 0 to 2.00s. We know that the work done on the particle is given by:

W = FΔx

From part (c), we know that the force acting on the particle is zero. Therefore, the work done on the particle is zero.

Conclusion: (a) The kinetic energy of the particle at any time t is 2 J.(b) The acceleration of the particle is zero.(c) The force acting on it at any time t is zero.(d) The power being delivered to the particle at any time t is zero.(e) The work done on the particle in the interval t = 0 to 2.00s is zero.

The area of each parallelogram or triangle is 24 cm²,22.5 cm², 98 ft²,48 cm², 90 m², and  30 in² respectively.

In this skills practice problem, we are asked to find the perimeter and area of each parallelogram or triangle, based on their given dimensions. Let's start by defining the formulas for calculating the perimeter and area of each shape:

Perimeter of a parallelogram = 2 x (length + width)

Area of a parallelogram = base x height

Perimeter of a triangle = sum of the lengths of its sides

Area of a triangle = 1/2 x base x height

Now, let's apply these formulas to each shape:

Parallelogram with length 6 cm and width 4 cm:

Perimeter = 2 x (6 + 4) = 20 cm

Area = 6 x 4 = 24 cm²

Triangle with base 9 cm and height 5 cm:

Perimeter = 9 + 8 + 7 = 24 cm

Area = 1/2 x 9 x 5 = 22.5 cm²

Parallelogram with length 14 ft and width 7 ft:

Perimeter = 2 x (14 + 7) = 42 ft

Area = 14 x 7 = 98 ft²

Triangle with base 12 cm and height 8 cm:

Perimeter = 12 + 8 + 10 = 30 cm

Area = 1/2 x 12 x 8 = 48 cm²
