Step-by-step explanation:

ABCD is a rectangle meaning, AD = BC AND AB = DC. Since BC = PQ, we need to solve for PQ.

We know that QR = 10 cm, and the area of a rectangle is the length times the width. We know the area is 45 cm^2, so:

a = l * w

45 = 10 * PQ

PQ = 4.5

Since PQ = BC, then BC = 4.5. We know that the perimeter of the rectangle is 26 cm, we can solve for AB:

2(AB) + 2(BC) = 26

2(AB) + 2(4.5) = 26

2(AB) = 17

AB = 8.5

Step-by-step explanation:

Answer:

Step-by-step explanation:

Answer:

c - 12y

Step-by-step explanation:

a. L{x(t)} = 6e^(-s) / s, with the region of convergence Re(s) > 0.

b. L{x(t)} = 0, with the region of convergence being the entire complex plane, Re(s) > -∞.

c. L{x(t)} = 0

To evaluate the Laplace transforms of the given signals and determine their regions of convergence, let's examine each signal separately:

a. x(t) = 6(t - 1)

Taking the Laplace transform of x(t):

L{x(t)} = L{6(t - 1)}

Applying the time shift property of the Laplace transform:

L{6(t - 1)} = 6e^(-s) / s

The region of convergence (ROC) for this signal is Re(s) > 0.

b. x(t) = u(t + 1) - u(t - 1)

Using the definition of the unit step function, u(t):

u(t) = 1 for t ≥ 0

u(t) = 0 for t < 0

Breaking down x(t) into two terms:

x(t) = u(t + 1) - u(t - 1)

Taking the Laplace transform of each term separately:

L{u(t + 1)} = e^(-s) / s

L{u(t - 1)} = e^(-s) / s

Using the linearity property of the Laplace transform:

L{x(t)} = L{u(t + 1)} - L{u(t - 1)} = e^(-s) / s - e^(-s) / s = (e^(-s) - e^(-s)) / s = 0

Since the Laplace transform of x(t) is 0, the region of convergence is the entire complex plane, Re(s) > -∞.

c. x(t) = cos(2πt)[u(t + 1) - u(t - 1)]

Using the definition of the unit step function, u(t):

u(t) = 1 for t ≥ 0

u(t) = 0 for t < 0

Breaking down x(t) into two terms:

x(t) = cos(2πt)[u(t + 1) - u(t - 1)]

Taking the Laplace transform of each term separately:

L{cos(2πt)} = s / (s^2 + (2π)^2)

Using the time shift property of the Laplace transform for the unit step function:

L{u(t + 1)} = e^(-s) / s

L{u(t - 1)} = e^(-s) / s

Using the linearity property of the Laplace transform:

L{x(t)} = L{cos(2πt)[u(t + 1) - u(t - 1)]} = L{cos(2πt)} * (L{u(t + 1)} - L{u(t - 1)})

Substituting the Laplace transform values:

L{x(t)} = (s / (s^2 + (2π)^2)) * (e^(-s) / s - e^(-s) / s)

Simplifying:

L{x(t)} = (e^(-s) - e^(-s)) / ((s^2 + (2π)^2) * s) = 0

Similar to the previous signal, the Laplace transform of x(t) is 0, and the region of convergence is the entire complex plane, Re(s) > -∞.

In summary:

a. L{x(t)} = 6e^(-s) / s, with the region of convergence Re(s) > 0.

b. L{x(t)} = 0, with the region of convergence being the entire complex plane, Re(s) > -∞.

c. L{x(t)} = 0

The volume of the solid generated by revolving the region bounded by the curves y = 3x, y = x, and y = 9 about the y-axis can be found using the washer method.

First, let's find the points of intersection between the curves. Setting y = 3x and y = x equal to each other, we get:

3x = x

2x = 0

x = 0

So, the curves intersect at the point (0, 0).

Next, we'll find the limits of integration. The region r is bounded between y = x and y = 9. The lower limit of integration is x = 0, and the upper limit of integration is x = 3.

Now, let's consider a vertical slice of the region at a given x-value. The radius of the outer circle (larger radius) is y = 9, and the radius of the inner circle (smaller radius) is given by the equation of the line y = x. The thickness of the washer is dx.

The volume of each washer can be calculated using the formula V = π(R^2 - r^2)dx, where R is the radius of the outer circle and r is the radius of the inner circle.

For the given problem, the volume can be calculated as follows:

V = ∫[0,3] π((9)^2 - (x)^2)dx

Evaluating this integral, we get:

V = π∫[0,3] (81 - x^2)dx

 = π[(81x - (x^3)/3)]|[0,3]

 = π[(81(3) - (3^3)/3) - (81(0) - (0^3)/3)]

 = π[243 - 9]

 = 234π

Therefore, the volume of the solid generated is 234π cubic units.

Answer:

-64

Step-by-step explanation:

The option that gives the correct answer when we evaluate p(2) of the given polynomial is; Option D; P(2) = -64

We are given the polynomial;

p(x) = 9x⁴ - 45x³ + 37x² + x + 2

We are told he wants to determine the remainder by evaluating p(2). This means we will plug in 2 for x in the polynomial to get the remainder.

Thus;

p(2) = 9(2)⁴ - 45(2)³ + 37(2)² + 2 + 2

p(2) = 9(16) - 45(8) + 37(4) + 4

p(2) = 144 - 360 + 148 + 4

p(2) = -64

In conclusion, p(2) = -64 and Option D is the correct option.

The total volume of the solid shape is 550π/3 cm³.

To find the total volume of the solid shape, we need to calculate the volumes of the cone and the hemisphere separately and then add them together.

1. Volume of the cone:

The formula for the volume of a cone is V_cone = (1/3) * π * r^2 * h, where r is the radius of the cone's base and h is the height of the cone.

Given that the base diameter is 10 cm, the radius of the cone is 10/2 = 5 cm.

Plugging in the values, we have:

V_cone = (1/3) * π * (5 cm)^2 * 12 cm = 100π cm³.

2. Volume of the hemisphere:

The formula for the volume of a hemisphere is V_hemisphere = (2/3) * π * r^3, where r is the radius of the hemisphere.

Since the diameter of the hemisphere is 10 cm, the radius is 10/2 = 5 cm.

Plugging in the values, we have:

V_hemisphere = (2/3) * π * (5 cm)^3 = 250π/3 cm³.

Finally, to get the total volume of the solid shape, we add the volumes of the cone and the hemisphere:

Total volume = V_cone + V_hemisphere = 100π cm³ + 250π/3 cm³ = (300π + 250π)/3 cm³ = 550π/3 cm³.

Given the parameter values n, δ, A₀, and k₀, the endogenous technological progress A(t) can be calculated using a recursive formula. The value of physical capital k(t) can also be determined using a separate recursive formula. The specific values depend on additional parameters not provided.

To compute the value of the endogenous technological progress A(t) at time t, we can use the following recursive formula:

A(t+1) = (1 - δ) * A(t) + n * k(t)^θ

where:

- A(t) represents the value of technological progress at time t.

- δ is the depreciation rate, which is 0.1 in this case.

- n is the exogenous growth rate of technological progress, which is 0.01 in this case.

- k(t) is the value of physical capital at time t.

- θ is the elasticity of output with respect to capital, which is not provided in the given information.

To compute k(t), we can use the following formula:

k(t+1) = (1 - δ) * k(t) + i(t)

where:

- k(t) represents the value of physical capital at time t.

- δ is the depreciation rate, which is 0.1 in this case.

- i(t) is the investment at time t.

Since the investment i(t) is not given in the provided information, we cannot determine the exact values of A(t) and k(t) for each time period. However, we can use the given initial values to compute their values for the initial time period (t = 0).

Using the provided initial values:

A(0) = 5

k(0) = 10

We can substitute these values into the recursive formulas to compute A(1) and k(1):

A(1) = (1 - 0.1) * 5 + 0.01 * 10^θ

k(1) = (1 - 0.1) * 10 + i(0)

The values of A(1) and k(1) can then be used to compute A(2) and k(2), and so on, by iteratively applying the recursive formulas. The specific values of A(t) and k(t) for each time period would depend on the values of θ and the investment i(t), which are not provided.

No, a fraction is not a term. The distributive property can be applied to fractions because it is a general mathematical principle.

A fraction is not considered a term in the traditional sense. It is a mathematical expression that represents division. However, the distributive property can still be applied to fractions because the property itself is a fundamental rule of arithmetic that extends beyond specific types of expressions.

The distributive property states that for any real numbers a, b, and c:

a × (b + c) = (a × b) + (a × c).

When working with fractions, we can apply the distributive property as follows:

Let's consider the expression: a × (b/c).

We can rewrite this as: (a × b)/c.

Now, let's distribute the 'a' to 'b' and 'c':

(a × b)/c = (a/c) × b.

In this step, we applied the distributive property to the fraction (a/c) by treating it as a whole.

Although fractions represent division, we can still use the distributive property because it is a general mathematical principle that allows for manipulating expressions involving addition, subtraction, multiplication, and division.

The domain is the collection of possible inputs (values of x) for which a function is defined, according to mathematical terminology. The domain of a function is usually determined by analyzing its graph, which represents all feasible inputs to the function.

The domain of a graphed function is given in the question; it is the range of values for x that are represented on the horizontal axis of the graph. The domain can also be written as an interval of the form [a, b], where a and b are the leftmost and rightmost values of x that appear on the graph respectively.

When looking at the graph, we can see that the leftmost value is -6, and the rightmost value is 9. As a result, the domain of the function is given by the inequality -6 ≤ x ≤ 9, which is option A: -6≤x≤9. This is because any value of x that lies between -6 and 9 (inclusive) is shown on the graph, and any other value of x is not displayed on the graph.

The domain is one of the most important elements of any function, as it determines the set of all possible input values that a function can accept. Knowing the domain of a function is critical in determining if a function is defined for a given input value, among other things.
