3w + 5 = 23

pls help I need to show work

Answer:

See below.

Step-by-step explanation:

The x-intercept occurs when k(x) = 0.

3x - 6 = k(x) = 0

3x - 6 = 0

3x = 6

x = 2

The x-intercept occurs (2, 0).

The y-intercept occurs when x = 0.

k(x) = 3x - 6

k(x) = 3(0) - 6

k(x) = -6

The y-intercept occurs at (0, -6).

Answer: C. y = -5

Step-by-step explanation: So, first in this equation you will add 7 on both sides and that cancels out the negative 7 and 18 plus 7 equals 25. So, now you have 25 = -5y. Now, you will divide -5 on both sides which cancels out the -5y and 25 divided by -5 equals -5. So, that gives you your answer of y = -5. Hope this helps^-^.

An Edgeworth box is used to represent the initial allocation of goods between David and Wilson based on their endowments of onion rings and chips.

An Edgeworth box is a graphical representation used to analyze the allocation of goods between two individuals.

In this case, we consider David and Wilson's initial endowments of onion rings and chips.

To draw the Edgeworth box, we create a rectangular box where the horizontal axis represents the quantity of onion rings (q1) and the vertical axis represents the quantity of chips (q2). The box is divided into four quadrants, representing the allocation of goods to each individual.

Based on their initial endowments, David has 35 onion rings and 10 chips, while Wilson has 5 onion rings and 20 chips.

We label the initial allocation of goods as point "e" within the Edgeworth box, indicating the quantities of onion rings and chips for each person.

By visually representing the initial allocation in the Edgeworth box, we can analyze the potential for trade and the possibility of mutually beneficial exchanges between David and Wilson based on their preferences and utility functions.

Step-by-step explanation:

The value of x in the similar polygons is 7.

Two polygons are similar if their corresponding angles are congruent and their corresponding sides are in proportion.

Therefore, the polygons WXY and STU are similar.

Hence, using proportion, let's find the value of x

3 / 9 = 4 / x + 5

cross multiply

3(x + 5) = 9 × 4

3x + 15 = 36

subtract 15 from both sides of the equation

3x + 15 - 15 = 36 - 15

3x = 21

divide both sides by 3

x = 21 / 3

x = 7

Therefore,

x = 7

The best option is to Convert it to a decimal and multiply is the best way to describe rate in simple interest formula. The correct option is A.

Simple interest is a quick and simple formula for figuring out how much interest will be charged on a loan. The daily interest rate, the principal, and the number of days between payments are multiplied to calculate simple interest.

Simple Interest (S.I.) is a method for figuring out how much interest will accrue on a specific principal sum of money at a certain rate of interest. For instance, if someone borrows Rs. 5000 at a rate of 10 p.a. for two years, they will pay S.I. on the borrowed money for those two years.

Therefore, if you are a borrower, the interest rate is the sum you pay for borrowing money and is expressed as a percentage of the overall loan amount. The correct option is A.

The equilibrium number of firms will be the smallest integer such that the price is 6 or higher. This occurs when n = 2. At this equilibrium, the price is P = 6, the output of each firm is y = 3/2, the industry's output is Y = 3, and the profit of each firm  = -2.

a) Supply curve of an individual firm

The price received by the individual firm will be P. Its demand curve is given by

D(p) = 20 - p.

Each firm chooses output to maximize its profit. Profit maximization occurs when the price is equal to the marginal cost. Mathematically,

P = MC(y)

4y = P

y = P/4

Thus the supply curve of the firm is y = P/4

b) The smallest price at which the product can be sold. The product can be sold at the minimum of the supply curve, which is y = 0, given P ≥ 0. Therefore the smallest price is P = 0.

c) Equilibrium price and output

Equilibrium occurs when each firm is producing at its profit-maximizing output given the output of other firms. Let the number of firms in the industry be n. The output of the industry is Y = ny. The industry supply curve is given by

S(P) = nP/4

The equilibrium price intersects the industry supply curve with the demand curve. Thus the equilibrium price satisfies

S(P) = Y

nP/4 = 20 - P

=> P = 80/(4 + n).

The equilibrium number of firms is the number that makes the industry supply curve equal to the demand curve. Thus

20 - P = nP/4

=> P = 80/(4 + n)

=> n = (80 - 20P)/P

= 20/P - 4.

Thus the equilibrium number of firms is a function of P and can range between 1 and infinity, but it must be an integer. The equilibrium output of each firm is given by

y = P/4 = 20/(4n + n²)

The equilibrium output of the industry is given by

Y = n

y = 5/P = (n² + 4n)/80.

d) Equilibrium number of firms with new demand curve D(p) = 21 - p.

The intersection of this curve with the marginal cost curve is at p = 21/5. This is greater than the minimum possible price of 0. Thus there is a positive profit to be earned in this industry, and new firms can enter the market.

e) Equilibrium price and output with new demand curve with the new demand curve D(p) = 21 - p, the industry supply curve and the equilibrium price are as given in part (d). The equilibrium output of each firm is given by y = P/4 = 21/20, and the equilibrium output of the industry is given by Y = 21/4.

f) Equilibrium number of firms, price, output, and profit with demand curve D(p) = 24 - p. This demand curve intersects the marginal cost curve at p = 6. The minimum possible price is P = 0. Thus there is a range of prices from 0 to 6 where firms can profit positively.

The equilibrium number of firms will be the smallest integer such that the price is 6 or higher. This occurs when n = 2. At this equilibrium, the price is P = 6, the output of each firm is y = 3/2, the output of the industry is Y = 3, and the profit of each firm is (6)(3/2) - (2)(2(3/2)² + 8) = -2.

We found the speed of the particle as √(4096sin²(2t) + y²cos²(t)), where t is the time and we identified the times when the particle comes to a stop as t = π/2, 3π/2, 5π/2, ...

To calculate the speed of the particle, we first need to find its velocity vectors. The velocity vector of a particle is the derivative of its position vector with respect to time.

Given:

x = 32cos(2t) (Equation 1)

y = ysin(t) (Equation 2)

Differentiating Equation 1 with respect to time (t):

dx/dt = -64sin(2t) (Equation 3)

Differentiating Equation 2 with respect to time (t):

dy/dt = ycos(t) (Equation 4)

So, the velocity vector v(t) = (dx/dt)i + (dy/dt)j is given by:

v(t) = -64sin(2t)i + ycos(t)j

Step 2: Speed of the particle

The speed of the particle at any given time t is the magnitude of its velocity vector. Let's calculate the speed using the formula:

Speed (|v(t)|) = sqrt((dx/dt)² + (dy/dt)²)

Substituting the values from Equations 3 and 4 into the speed formula, we get:

Speed (|v(t)|) = sqrt((-64sin(2t))² + (ycos(t))²)

Simplifying further:

Speed (|v(t)|) = sqrt(4096sin²(2t) + y²cos²(t))

Step 3: Finding when the particle comes to a stop

To determine when the particle comes to a stop, we need to find the values of t for which the speed of the particle is zero. In other words, we need to solve the equation:

Speed (|v(t)|) = 0

From the equation derived in Step 2, we can see that the speed will be zero only if both terms inside the square root are zero simultaneously. This leads us to two cases:

Case 1: sin²(2t) = 0

For this case, we solve sin(2t) = 0, which gives us t = 0, π/2, π, 3π/2, 2π, ...

Case 2: y²cos²(t) = 0

For this case, we solve ycos(t) = 0. Since y is a constant and cannot be zero (as it is not given), we conclude that cos(t) = 0. This gives us t = π/2, 3π/2, 5π/2, ...

By combining the solutions from both cases, we find that the particle comes to a stop at t = π/2, 3π/2, 5π/2, ...
