Answer:

9.013 square units

Step-by-step explanation:

The flux of the vector-field F = 1i + 1j + 2k across the surface S is 2. We find out the flux of the vector-field using Green's Theorem.

Flux form of Green's Theorem for the given vector-field

φ = ∫ F.n ds

= ∫∫ F. divG.dA

Here G is equivalent to the part of the plane = 2x+4y+z = 2.

and given F = 1i + 1j + 2k

divG = div(2x+4y+z = 2) = 2i + 4j + k

Flux = ∫(1i + 1j + 2k) (2i + 4j + k) dA

φ = ∫ (2 + 4 + 2)dA

= 8∫dA

A = 1/2 XY (on the given x-y plane)

2x+4y =2

at x = 0, y = 1/2

y = 0, x = 1

1/2 (1*1/2) = 1/4

Therefore flux = 8*1/4 = 2

φ = 2.

The statement "Some unsound arguments are valid" is false.

The statement "Some unsound arguments are valid" is false.

A valid argument is a statement that follows the rules of logic.

An argument is known to be sound when it is valid and has true premises. When the premises of an argument are correct, the argument is considered sound. When an argument is valid, it follows logically from its premises, which are the statements that provide evidence or support for the argument's conclusion.

The unsound argument is the one that contains at least one false premise.

The sound argument is the one that contains only true premises and is valid (that is, follows logically from the premises).

If an argument is unsound, it can never be valid because it contains at least one false premise.

Therefore, the statement "Some unsound arguments are valid" is false.

The surface area of the right cylinder in terms of pi is 76π units².

A cylinder is simply a 3-dimensional shape having two parallel circular bases joined by a curved surface.

The surface area of a cylinder is expressed as;

Surface area = ( 2πr² ) + ( 2πrh )

Where r is the radius of the circular base, h is height and π is constant pi.

From the diagram:

Radius r = 8 units

Height h = 3 units

Surface area =?

Plug the given values into the above formula and solve for the surface area:

Surface area = ( 2πr² ) + ( 2πrh )

Surface area = ( 2π × 8² ) + ( 2π × 3 × 8 )

Surface area = ( 2π × 64 ) + ( 2π × 24 )

Surface area = 128π + 48π

Surface area = 176π units²

Therefore, the surface area is 176π units².

Step-by-step explanation:

Answer:

The cannonball lands at approximately 5.093 unit distance from the point of fire

Step-by-step explanation:

The given parameters are;

The arc denoting the equation of motion of the cannon is y₁ = -0.5·x² + 2.5·x + 1

The slope of the field where in the direction the cannon is fired is y₂ = 1.5·x

The points where the cannonball land on the slopping field is given as rightly pointed by equating the two equations, the cannonball path path and the field path as follows;

At the point of contact of the cannonball and the field, the y-values of both equation will be equal

y₁ = y₂

∴ -0.5·x² + 2.5·x + 1 = 0.15·x

Which gives;

-0.5·x² + 2.5·x - 0.15·x + 1 = 0

-0.5·x² + 2.35·x + 1 = 0

-(-0.5·x² + 2.35·x + 1) = 0.5·x² - 2.35·x - 1 = 0

0.5·x² - 2.35·x - 1 = 0

The above equation is in the general form of a quadratic equation, which is given as follows;

a·x² + b·x + c = 0

By the quadratic equation, we have;

\(x = \dfrac{-b\pm \sqrt{b^{2}-4\cdot a\cdot c}}{2\cdot a}\)

Plugging in the values, gives;

\(x = \dfrac{2.35\pm \sqrt{(2.35)^{2}-4\cdot (0.5)\times (-1)}}{2\cdot (0.5)} = \dfrac{2.35\pm \sqrt{7.5225}}{1} =2.35 \pm \sqrt{7.5225}\)

∴ x ≈ 5.093 or x ≈ -0.393

Therefore, the cannonball will takeoff at x ≈ -0.393 and land at x ≈ 5.093

The height from which they fire the cannon is given by the substituting the value of x ≈ -0.393 into the equation for the path of the cannonball, to give;

\(y_{(initial)}\) = -0.5·(-0.393)² + 2.5·(-0.393) + 1 = -0.0597

\(y_{(initial)}\) ≈ -0.0597.

However, the actual initial height from which the cannonball is fired given by placing x = 0, which gives y = 1, which is the reason for the other (negative) value for x. Please see the attached graph created with Microsoft Excel.

To spend twice as much time in the air, the juggler must toss the balls to a height of 4.4 yards.

The time it takes for an object to fall to the ground is given by the equation:

t = sqrt(2h/g)

where h is the height of the object and g is the acceleration due to gravity (9.8 m/s²).

If the juggler wants the balls to spend twice as much time in the air, they need to toss them to a height that is four times higher. So, the new height must be:

h = 4 * 2.2 = 4.4 yards

Therefore, the juggler must toss the balls to a height of 4.4 yards if they want them to spend twice as much time in the air.

Here are some other things to consider:

The juggler's technique may also affect how long the balls stay in the air. For example, if they throw the balls with a lot of force, they will stay in the air for longer.

The air resistance may also affect how long the balls stay in the air. For example, if the air is very humid, the balls will slow down more quickly and will not stay in the air for as long.

Answer:

Step-by-step explanation:

To obtain the weighting sequence of the system described by the given difference equation, we can use the Z-transform.

The difference equation can be written in the Z-domain as follows:

Z^2X(Z) - Z^2X(Z)z^(-1) + 0.25X(Z) = Z^2U(Z)

Where X(Z) and U(Z) are the Z-transforms of the sequences x(k) and u(k), respectively.

Simplifying the equation, we get:

X(Z)(Z^2 - Z + 0.25) = Z^2U(Z)

Now, we can solve for X(Z) by dividing both sides by (Z^2 - Z + 0.25):

X(Z) = Z^2U(Z) / (Z^2 - Z + 0.25)

Next, we need to find the inverse Z-transform of X(Z) to obtain the weighting sequence x(k).

Since the initial conditions are given as x(0) = 1 and x(1) = 2, we can use these initial conditions to find the inverse Z-transform.

Using partial fraction decomposition, we can express X(Z) as:

X(Z) = A/(Z - 0.5) + B/(Z - 0.5)^2

Where A and B are constants.

Now, we can find the values of A and B by equating the coefficients on both sides of the equation. Multiplying both sides by (Z^2 - Z + 0.25) and substituting Z = 0.5, we get:

A = 0.5^2U(0.5)

Similarly, differentiating both sides of the equation and substituting Z = 0.5, we get:

A = 2B

Solving these equations, we find A = U(0.5) and B = U(0.5) / 4.

Finally, applying the inverse Z-transform to X(Z), we obtain the weighting sequence x(k) as:

x(k) = U(0.5) (0.5^k + (k/4)(0.5^k-1))

Therefore, the weighting sequence of the system described by the given difference equation is x(k) = U(0.5) (0.5^k + (k/4)(0.5^k-1)), where U(0.5) is the unit step function evaluated at Z = 0.5.

We are given the two equations are:

10x + 7y + z = 4---------(1)

\(\frac{x^2}{25} +\frac{y^2}{9} =1-------------(2)\)

equation(1) is written as

z = 4 - 10x - 7y-----------(3)

The surface area is given by the equation:

A(S) = ∫∫√[(∂f/∂x)² + (∂f/∂y)² + 1]dA------------(4)

compare equation(4) with equation(3) we get the values of ∂f/∂x and

∂f/∂y

∂f/∂x = -10

∂f/∂y = -7

substitute these values in equation(4)

A(S) = ∫∫√[(-10)² + (-7)² + 1]dA

A(S) = ∫∫√[100 + 49 + 1]dA

A(S) = ∫∫√[150]dA

A(S) = √150 ∫∫dA

Where ∫∫dA is the elliptical cylinder

From the general form of an area enclosed by an ellipse with the formula;

comparing x²/a² + y²/b² = 1  with x²/25 + y²/9 = 1, from that we get the values of a and b

a = 5 and b = 3

So, the area of the elliptical cylinder = πab

If x is an int and y is a float then only option that is not legal is D) x = (int) y.

Option A is legal because an int can be assigned to a float without any issues. The float will simply contain the same value as the int, but with a decimal point (e.g. 5 will become 5.0). Option B is not recommended because it involves converting a float to an int. The decimal point will be dropped, so information will be lost. However, it is still legal to do so. Option C is legal because it explicitly converts the int to a float, which can then be assigned to y. Option D is not legal because it involves converting a float to an int. This can lead to unexpected behavior, such as truncating the decimal point or rounding the value. It is generally safer to avoid such conversions. Option E is not correct because option D is not legal, as explained above.

The length of arc FH in the circle 8.37 units.

We know that,

In mathematics, a circle is a closed two-dimensional shape that consists of all the points in a plane that are a fixed distance (called the radius) from a given point (called the center). Circles are used in many areas of mathematics and science, including geometry, trigonometry, and physics. They have important applications in areas such as engineering, architecture, and computer graphics.

Here,

To find the length of arc FH, we first need to find the measure of angle FGH in degrees. Since the sum of angles in a triangle is 180 degrees, we can use the fact that angles FGH and FGF are supplementary to find:

m∠FGF = 180 - m∠FGH = 180 - 86 = 94 degrees

Since FGF is an inscribed angle that intercepts arc FH, the measure of arc FH is twice the measure of angle FGF. So we have:

m(arc FH) = 2 × m∠FGF = 2 × 94 = 188 degrees

To find the length of arc FH, we need to know the circumference of circle G. Since we know that FG = 16 units, we can use this to find the radius of the circle:

r = FG/2 = 16/2 = 8 units

The circumference of the circle is then:

C = 2πr = 2π(8) = 16π

To find the length of arc FH, we need to find the fraction of the circumference that arc FH represents, and then multiply this by the total circumference. Since the measure of arc FH is 188 degrees out of a total of 360 degrees in the circle, we have:

Length of arc FH = (188/360) × C

Substituting the value of C, we get:

Length of arc FH = (188/360) × 16π

Simplifying and rounding to the nearest hundredth, we get:

Length of arc FH ≈ 8.37 units
