If A be a 5 × 4 matrix and let b and c be two vectors in \(R^5\) and we are told that Ax = b is inconsistent, then the number of solutions for A * x = c could be unique, infinite, or none, based on the given information.

Since A is a 5x4 matrix and b and c are vectors in \(R^5\), we know that A * x = b and A * x = c are systems of linear equations with x being a 4x1 vector.
We are given that A * x = b is inconsistent, which means it has no solutions. Now, let's analyze the system A * x = c.
1. If A * x = c has a unique solution, it would mean that there is a vector x for which the system A * x = b is inconsistent but A * x = c is consistent. This is possible.
2. If A * x = c has infinitely many solutions, it would mean that the system A * x = c has a free variable and there are infinitely many combinations of x that satisfy the equation. This is also possible.
3. If A * x = c has no solution (inconsistent), then both systems A * x = b and A * x = c would be inconsistent, which is also possible.
Therefore, the number of solutions for A * x = c could be unique, infinite, or none, based on the given information.

This power series expansion represents the function f(x) as an infinite sum of powers of x, centered at x = 0, which is the Maclaurin series for f(x).

To obtain the Maclaurin series for the function f(x) = x cos(7x), we can use the power series expansion of the cosine function, which is:

cos(x) = 1 - (x^2)/2! + (x^4)/4! - (x^6)/6! + ...

Substituting 7x for x in the power series expansion, we have:

cos(7x) = 1 - ((7x)^2)/2! + ((7x)^4)/4! - ((7x)^6)/6! + ...

Now, we multiply each term of the power series expansion of cos(7x) by x:

x cos(7x) = x - (7x^3)/2! + (7^2 x^5)/4! - (7^3 x^7)/6! + ...

The Maclaurin series for the function f(x) = x cos(7x) is given by the summation of the terms:

f(x) = x - (7x^3)/2! + (7^2 x^5)/4! - (7^3 x^7)/6! + ...

A decoder with 64 outputs has 6 inputs while a multiplexer with 32 inputs has 5 control lines.

A decoder is a combinational circuit that converts binary information from n input lines to a maximum of 2ⁿ unique output lines. If the decoder has 64 output lines, it means it has to process 6 bits of information from its inputs. Hence, a decoder with 64 outputs has 6 inputs. Therefore, the number of inputs a decoder has, if it has 64 outputs, is 6.52.

A multiplexer is a combinational circuit that selects a single data input line from a set of data input lines to pass through to the output based on the select lines. The number of select lines a multiplexer has determines the number of data inputs it can accommodate.

The formula to find the number of select lines a multiplexer has is:

2ⁿ ≥ a number of inputs where n is the number of select lines. If a multiplexer has 32 inputs, n would be 5 (since 2⁵=32). Therefore, a multiplexer with 32 inputs has 5 control lines. So, the number of control lines a multiplexer has if it has 32 inputs is 5.

The volume of the solid bounded by the cylinder z = 25 – y² and the plane x = 2 in the first octant is 128π/3 cubic units.

To find the volume, we need to set up a double integral over the region of integration in the xy-plane. The region is the part of the xy-plane that lies inside the cylinder x² + y² = 4 and above the x-axis. This region can be described by 0 ≤ x ≤ 2 and 0 ≤ y ≤ √(4 - x²).

The integral to find the volume is given by V = ∬R (25 - y²) dA, where R is the region of integration in the xy-plane. This can be rewritten as V = ∫0² ∫0√(4-x²) (25 - y²) dy dx.

Evaluating this integral gives V = 128π/3 cubic units. Therefore, the volume of the solid is 128π/3 cubic units.

The recursive function is given as:

f(n+1)=1/3f(n)

So then we multiply both sides by 3:

3f(n+1)=f(n)

Then we set n=2:

3f(2+1)=f(2)

Which comes to be:

f(2)=3f(3)

Next we set n=1:

f(1)=3f(1+1)

Which is:

f(1)=3f(2)

Then we substitute:

f(1)=3*3f(3)

The average speed for the entire trip is approximately 142.73 km/h.

The total distance traveled by the woman can be determined by summing up the distances covered during each leg of her trip. To find the average speed for the entire trip, we divide the total distance by the total time taken.

First, let's calculate the distances traveled during each leg of the trip:

Distance 1: 90.0 km/h * (25.0 min / 60) h = 37.5 km

Distance 2: 75.0 km/h * (20.0 min / 60) h = 25.0 km

Distance 3: 0 km (since there is no movement during the 35.0 min stop)

Distance 4: 400 km/h * (30.0 min / 60) h = 200 km

Now, we can calculate the total distance:

Total distance = Distance 1 + Distance 2 + Distance 3 + Distance 4

             = 37.5 km + 25.0 km + 0 km + 200 km

             = 262.5 km

Therefore, the total distance between her starting point and destination is 262.5 km.

To find the average speed for the entire trip, we divide the total distance by the total time taken:

Total time = 25.0 min + 20.0 min + 35.0 min + 30.0 min = 110.0 min

Average speed = Total distance / Total time

            = 262.5 km / (110.0 min / 60) h

            ≈ 142.73 km/h

Thus, the average speed for the entire trip is approximately 142.73 km/h.

Step-by-step explanation:

Therefore, the line integral of F along the straight line path C1 is 9/2. Therefore, the line integral of F along the curved path C2 is 4/5.

a. To find the line integral of F along the straight line path C1: r(t) = ti + tj + tk from (0,0,0) to (1,1,1), we can parameterize the path and evaluate the integral:

r(t) = ti + tj + tk

dr/dt = i + j + k

The line integral is given by:

∫ F · dr = ∫ (3y)i + (2x)j + (4z)k · (dr/dt) dt

= ∫ (3t)(j) + (2t)(i) + (4t)(k) · (i + j + k) dt

= ∫ (2t + 3t + 4t) dt

= ∫ 9t dt

= (9/2)t^2

Evaluating the integral from t = 0 to t = 1:

∫ F · dr = (9/2)(1^2) - (9/2)(0^2) = 9/2

b. To find the line integral of F along the curved path C2: r(t) = ti + t^2j + t^4k from (0,0,0) to (1,1,1), we follow a similar process:

r(t) = ti + t^2j + t^4k

dr/dt = i + 2tj + 4t^3k

The line integral is given by:

∫ F · dr = ∫ (3y)i + (2x)j + (4z)k · (dr/dt) dt

= ∫ (3t^2)(j) + (2t)(i) + (4t^4)(k) · (i + 2tj + 4t^3k) dt

= ∫ (4t^4) dt

= (4/5)t^5

Evaluating the integral from t = 0 to t = 1:

∫ F · dr = (4/5)(1^5) - (4/5)(0^5) = 4/5
