The formula for the volume of a cone is:

V = (1/3)πr²h

where r is the radius of the base, h is the height of the cone, and π is pi.

In this case, the slant height is given as 17 cm, which we can use with the radius to find the height of the cone using the Pythagorean theorem:

h² = s² - r²

h² = 17² - 8²

h² = 225

h = 15

Now that we have the height, we can plug in the values for r and h into the formula for the volume:

V = (1/3)π(8²)(15)

V = (1/3)π(64)(15)

V = (1/3)(960π)

V = 320π

Therefore, the volume of the cone is 320π cubic cm. Answer: 320π.

The percentage of members that voted is 70%.

The art club had an election to select a president. 42 out of the 60 members of the art club voted in the election.

Therefore, the percentage of the members that voted can be calculated as follows;

percentage that voted = number of people that voted / total number members × 100

Therefore,

number of people that voted = 42

total number members = 60

Hence,

percentage that voted = 42 / 60 ×100

percentage that voted = 4200 / 60

Therefore,

percentage that voted = 70%

Explanation:

The two angles shown are a linear pair. They are adjacent and supplementary.

Supplementary angles add to 180

(8x+1) + (4x+11) = 180

8x+1+4x+11 = 180

(8x+4x) + (1+11) = 180

12x+12 = 180

12x+12-12 = 180-12 ... subtract 12 from both sides

12x = 168

12x/12 = 168/12 ... divide both sides by 12

x = 14

Answer:

x=14

Step-by-step explanation:

A line has 180 degrees, so add your two equations and set them equal to 180. Then all you have to do is solve for x.

\(180= 8x+1+4x+11\)

\(180= 12x+12\)

\(168=12x\)

\(14=x\)

If you want to find the answer for each angle, then just plug 14 in for x.

8(14)+1= 113

4(14)+11= 67

The amount of land the railroad companies received for each mile of track they laid varied depending on the specific circumstances and agreements.

However, a common benchmark used during the construction of railroads in the United States was the granting of land through the Homestead Act of 1862. Under this act, railroad companies were granted approximately 6,400 acres (10 square miles) of land for every mile of track laid. This land was typically located alongside the tracks and served as an incentive for the companies to expand and develop the rail network across the country.

The order of the differential equation d²y/dx² + 4x(dy/dx) = d³(cos(2x))/dx³ is 3.

The order of a differential equation is determined by the highest derivative present in the equation. In the given differential equation, the highest derivative is the third derivative, d³(cos(2x))/dx³. Since this is the highest derivative and there are no higher-order derivatives present, the order of the differential equation is 3. This means that the equation involves up to the third derivative of the dependent variable y with respect to the independent variable x.

Answer:

Divide both sides by -3.

Step-by-step explanation:

This question is asking you how to get from step 1: \(-3(p-7) = -15\) to step 2: \(p - 7 = 5\).

We can see that the expression inside of the parentheses (p - 7) didn't go away from step 1 to step 2, and the term that was being multiplied by (p-7) had gone away. The only way you can "get rid" of a multiplied term is by doing the inverse of multiplication, which is division. Thus, you have to divide both sides by -3 to get to step 2.

The function u is harmonic and the harmonic conjugate of u is

v(x,y) = -ln|x| + ln|y| + C.

(c) Let's verify if the given function u = xy -x + y is harmonic:

The Laplacian of a function u is defined as the sum of the second partial derivatives with respect to the x and y variables. For the function u = xy - x + y, the Laplacian can be calculated as follows:

∇^2 u = ∂^2 u/∂x^2 + ∂^2 u/∂y^2 =

∇^2 u = 2 + 1 = 3

Since the Laplacian of u is a constant (3), it follows that u is a harmonic function in the region where it is defined.

Now let's find the harmonic conjugate of u:

A harmonic conjugate of a harmonic function u is a function v such that u + iv is analytic (complex differentiable), where i is the imaginary unit. To find the harmonic conjugate of u, we integrate the partial derivative of u with respect to x with respect to x and the partial derivative of u with respect to y with respect to y.

The partial derivative of u with respect to x is y - 1, and the partial derivative of u with respect to y is x. Thus, the harmonic conjugate of u is given by:

v(x,y) = ∫ (y - 1) dx + ∫ x dy

v(x,y) = xy - x + ∫ x dy

v(x,y) = xy - x + (1/2) y^2 + C,

where C is an arbitrary constant of integration.

(e) Let's verify if the given function u = In Izl for Rez > 0 is harmonic:

The Laplacian of the function u = In Izl for Rez > 0 can be calculated as follows:

∇^2 u = ∂^2 u/∂x^2 + ∂^2 u/∂y^2

∇^2 u  = (1/z^2) ∂^2 u/∂z^2

∇^2 u = 0, for Rez > 0

Since the Laplacian of u is 0, it follows that u is a harmonic function in the region where it is defined.

Now let's find the harmonic conjugate of u:

A harmonic conjugate of u is a function v such that u + iv is analytic. To find the harmonic conjugate of u, we integrate the partial derivative of u with respect to x with respect to x and the partial derivative of u with respect to y with respect to y.

The partial derivative of u with respect to x is -y/x, and the partial derivative of u with respect to y is x/y. Thus, the harmonic conjugate of u is given by:

v(x,y) = -∫ (y/x) dx + ∫ (x/y) dy

v(x,y) = -ln|x| + ln|y| + C, where C is an arbitrary constant of integration.

The explicit formula for the population growth is P(t) = 9 * (1 + 0.08)^t, where P(t) represents the population at time t, P0 is the initial population of 9, r is the growth rate of 8% or 0.08, and t is the time in years. Using this formula, we can calculate the population after 9 years which is approximately 16.03

To find the explicit formula for the population growth, we use the exponential growth model formula P(t) = P0 * (1 + r)^t. In this case, P0 is given as 9, and the growth rate r is 8%, or 0.08 when expressed as a decimal. Plugging these values into the formula, we get P(t) = 9 * (1 + 0.08)^t.

To evaluate the population after 9 years, we substitute t = 9 into the formula and calculate: P(9) = 9 * (1 + 0.08)^9. Using a calculator or performing the calculation manually, the population after 9 years is approximately 16.03 (rounded to two decimal places).

Therefore, the population after 9 years, based on the exponential growth model with an initial population of 9 and a growth rate of 8%, is approximately 16.03

d) The equation 20 + 4r = 32 - 2r has one solution.

What is an equation with infinitely many solutions ?

The system of an equation has infinitely many solutions when the lines are coincident, and they have the same y-intercept.

Let's check which of the given equations have one solution , infinitely many solutions or no solution.

a)

3u + 40 + 2u = 6u - 30 - u

reordering the terms :

5u + 40 = 5u - 30

or subtract 5u from both sides.

5u - 5u + 40 = 5u - 5u - 30

40 = - 30

which is not possible , that meant this equation has no solution.

b)

2.2z + 3z = 4.5 - 3.2

2.2z + 3z = 4.5 - 3.2

5.2z = 1.3

z = 1.3/5.2

or

z = 13/52

This equation has one solution.

c)

2.3y + 3.2 - y = 2.1 + 1.3y + 1.1

Reordering the terms :

1.3y + 3.2 = 1.3y + 3.2

0 = 0

This equation has infinitely many solutions.

d)

20 + 4r = 32 - 2r

Reordering the terms :

6r = 12

r = 2

This equation has one solution.

Therefore , the answers are :

a) The equation 3u + 40 + 2u = 6u - 30 - u has no solution.

b) The equation 2.2z + 3z = 4.5 - 3.2 has one solution.

c) The equation 2.3y + 3.2 - y = 2.1 + 1.3y + 1.1 has infinitely many solutions.

The answer would be A because the person would go up 7 floors, go down 2, and go down five more.

Step-by-step explanation:

If the two firms do not cooperate, the payoff that North Springs and South Springs receive in the dominant-strategy equilibrium and the Nash equilibrium would depend on the specific game or scenario being played. Without more information about the specific game being played and the strategies of the two firms, it is impossible to provide a definitive answer.

However, in general, the dominant-strategy equilibrium refers to the situation where each player chooses their best strategy, regardless of what the other player does. The Nash equilibrium refers to the situation where each player chooses their best strategy given what the other player is doing. In some cases, the dominant-strategy equilibrium and the Nash equilibrium may be the same, but in other cases, they may differ.

So, in order to determine the payoff that North Springs and South Springs receive in these equilibria, more information about the game being played and the strategies of the two firms would be needed.
Based on the information given, we can analyze the payoff for both North Springs and South Springs firms in the dominant-strategy equilibrium and the Nash equilibrium.

Dominant-Strategy Equilibrium:
1. Identify each firm's dominant strategy (the best response regardless of the other firm's action).
2. Combine the dominant strategies for both firms to find the outcome.

Nash Equilibrium:
1. Identify each firm's best response given the other firm's action.
2. Find the outcome where both firms are simultaneously choosing their best responses.

Without specific numerical payoffs, I cannot provide the exact payoff amounts. However, once you have the payoff matrix, you can follow the steps mentioned above to find the payoffs for North Springs and South Springs in the dominant-strategy equilibrium and the Nash equilibrium.
