Two firms producing identical products engage in price competition. Cost of firm 1 is $20 per unit produced and cost of firm 2 is $15 per unit produced. There are no fixed costs. Firms produce only after they learn the quantity demanded. Each firm can choose any real number in the interval [15,25] as its price.
For tie-breaking we will assume that if both firms set the same price, all consumers purchase from firm 2.
The payoff/profit function of firm 1 is:
(p1 - 20)(100 - p1) if p1 is less than or equal to p2,
0 if p1 is greater than p2
The payoff/profit function of firm 2 is:
(p2 - 15)(100 - p2) if p2 is less than p1,
0 if p2 is greater than or equal to p1
Given all of this information, solve the following parts of the problem:
a) is p1 = 20, p2 = 19.50 a Nash Equilibrium?
b) is there a Nash Equilibrium in which Firm 2 makes a positive profit?
c) How many strategies does player 1 have?
d) is p1 = 15, p2 = 15 a Nash Equilibrium?
e) is p1 = 21, p2 = 21 a Nash Equilibrium?
Answers
a) No, p1 = 20, p2 = 19.50 is not a Nash Equilibrium.
b) Yes, there is a Nash Equilibrium in which Firm 2 makes a positive profit.
c) Player 1 has infinitely many strategies.
d) Yes, p1 = 15, p2 = 15 is a Nash Equilibrium.
e) No, p1 = 21, p2 = 21 is not a Nash Equilibrium.
What is Nash Equilibrium?Nash Equilibrium is a state of a strategic game where no player has an incentive to deviate from his or her chosen strategy after considering the strategies of other players. A game has more than one Nash equilibrium if players are unable to agree on a cooperative strategy to play.
Finding Nash Equilibrium
a) Is p1 = 20, p2 = 19.50 a Nash Equilibrium?No. Firm 1 has an incentive to decrease the price to 19.49, thus breaking the tie in its favour. So p1=20, p2=19.5 is not a Nash equilibrium.b) Is there a Nash Equilibrium in which Firm 2 makes a positive profit?Yes. There are several equilibria in which Firm 2 makes a positive profit. One such equilibrium is when both firms charge the same price of 15, at which both firms earn a profit of 375.c) How many strategies does player 1 have?Player 1 has infinitely many strategies to choose from as they can choose any real number in the interval [15,25] as their price.d) Is p1 = 15, p2 = 15 a Nash Equilibrium?Yes. This is a Nash Equilibrium because neither firm has an incentive to change their strategy as they are earning non-zero profits. Both firms earn a profit of 375.e) Is p1 = 21, p2 = 21 Nash Equilibrium?No. If Firm 1 changes its price to 20.99, its profit increases from 405 to 407.99. Therefore, p1=21 and p2=21 is not a Nash Equilibrium.Learn more about Nash equilibrium at

Leanna is signing, addressing, and mailing invitations by hand to previous customers
of her handmade pottery to inform them of an upcoming home show. She begins with
a list of 344 customers. After working for one hour she has 320 invitations remaining,
and 296 remaining after working for two hours. Assuming that Leanna’s work rate
remains the same, what sequence model in subscript notation models the number
of invitations remaining? Explain.
Answers
The arithmetic sequence is 344,320,296,.... and first term \(a_1\) = 344 and common difference d = -24 and nth term is \(a_n\)=368-24n.
What is word problem?
Word problems are often described verbally as instances where a problem exists and one or more questions are posed, the solutions to which can be found by applying mathematical operations to the numerical information provided in the problem statement. Determining whether two provided statements are equal with respect to a collection of rewritings is known as a Word problem in computational mathematics.
Here Total number of invitations = 344.
After one hour the number of invitations = 320
After two hour the number of invitations = 296
then the sequence is 344,320,296,....
Here \(a_1\) = 344 and common difference d = \(a_2-a_1\) = 320-344 =-24
Now using arithmetic sequence formula then,
\(a_n=a_1+(n-1)d\)
=> \(a_n\)=344+(n-1)-24
=> \(a_n\)=344-24n+24
=> \(a_n\)=368-24n
Here n represent the number.
Thus the arithmetic sequence is 344,320,296,.... and first term \(a_1\) = 344 and common difference d = -24 and nth term is \(a_n\)=368-24n.

which two parts of the vehicle are most important in preventing traction loss
Answers
The tires and the traction control system work in tandem to ensure maximum traction and stability, minimizing the risk of traction loss and improving overall vehicle control and safety.
The two most important parts of a vehicle in preventing traction loss are the tires and the traction control system.
Tires: Tires are the primary point of contact between the vehicle and the road surface. The quality and condition of the tires greatly influence traction. Tires with good tread depth and appropriate tread pattern are essential for maintaining grip on the road. Tread depth helps to channel water, snow, or debris away from the tire, preventing hydroplaning or loss of traction. Additionally, tire pressure should be properly maintained to ensure even contact with the road. Choosing tires suitable for the specific driving conditions, such as all-season, winter, or performance tires, is crucial for optimal traction and handling.
Traction Control System: The traction control system is a vehicle safety feature that helps prevent the wheels from slipping or spinning on low-traction surfaces. It uses various sensors to monitor the speed and rotation of the wheels. If the system detects a loss of traction, it will automatically reduce engine power and apply braking force to the wheels that are slipping. By modulating power delivery and braking, the traction control system helps maintain traction and prevent wheel spin, especially in challenging conditions like slippery roads or during quick acceleration.
The tires and the traction control system work in tandem to ensure maximum traction and stability, minimizing the risk of traction loss and improving overall vehicle control and safety.

Luna is making a rope ladder. Each
step of the ladder is 2½ feet wide and uses an additional
foot on each end of the step for the knot. Luna has a
rope that is 30 feet long. How many steps can she make from the rope?
Answers
By taking the quotient between the total length of rope and the length of rope needed for each step, we conclude that she can make 12 steps from the rope.
How many steps can she make from the rope?
We know that each step of the ladder needs 2½ feet of rope, and Luna has a rope that is 30 feet long.
To find the number of steps that she can make with that rope, we need to take the quotient between the length of the total piece of rope, and the length of rope needed for each step.
It is:
N = (30ft)/(2½ ft)
Notice that 2½ = 2.5
Replacing that in the fraction we get:
N = (30ft)*(2.5 ft) = 12
From this, we conclude that she can make 12 steps from the rope.

what is the measure of an angle if the measure of its two adjacent supplementry angles add up to 100 degrees.
Answers
The measure of the angle if the measure of its two adjacent supplementary angles add up to 100 degrees is 80 degrees.
Let the measure of the angle be x.
We are given that the measure of its other two supplementary angles is 100°
We know that:
The sum of the supplementary angles is equal to 180°.
So, we get that:
100° + x = 180°
Subtract 100° from both the sides:
x = 180° - 100°

A bookmark has an area of 150 square centimeters and a perimeter of 62 centimeters. what are the dimensions of the bookmark
Answers
The dimensions of the bookmark are length = 15 centimeters and width = 10 centimeters.
Let's denote the length of the bookmark as L and the width as W.
The area of a rectangle is given by the formula A = L * W, and the perimeter is given by P = 2L + 2W.
From the given information, we have two equations:
Equation 1: A = 150 square centimeters
Equation 2: P = 62 centimeters
Substituting the formulas for area and perimeter, we get:
Equation 1: L * W = 150
Equation 2: 2L + 2W = 62
To solve these equations, we can use substitution or elimination. Let's solve by substitution:
From Equation 1, we can express one variable in terms of the other:
L = 150 / W
Substituting this into Equation 2:
2(150 / W) + 2W = 62
300 / W + 2W = 62
300 + 2W^2 = 62W
2W^2 - 62W + 300 = 0
Now we have a quadratic equation. We can solve it by factoring, completing the square, or using the quadratic formula. In this case, let's use factoring:
\(2W^2 - 62W + 300 = 0\)
(W - 10)(2W - 30) = 0
This gives us two possible solutions:
W - 10 = 0 -> W = 10
2W - 30 = 0 -> W = 15
Since the width cannot be longer than the length, we discard the solution W = 15.
So, the width of the bookmark is W = 10 centimeters.
Now, we can substitute this value into Equation 1 to find the length:
L * 10 = 150
L = 150 / 10
L = 15

What is mensuration in real life?Measurement of agricultural fields, floor areas required for purchase/selling transactions. Measurement of volumes required for packaging milk, liquids, solid edible food items. Measurements of surface areas required for estimation of painting houses, buildings, etc.
According to the question:-
Side of an equilateral triangle equals a/3.
Therefore, the equilateral triangle's area is equal to (1/2)(a/3)2 sqrt (3) / 2 = a2 [sqrt (3)/ 36].
Hexagonal side equals b / 6.
The area is thus 6 (1/2) (b/6)^2 sqrt (3) / 2
= b^2 [ 3 sqrt (3) / 72] = b^2 [sqrt (3) / 24]
So
sqrt (3) / 36 a2 = sqrt (3) / 24 b2
So
A2 / B2 = [Sqrt(3)/24] / [Sqrt(3)/36]
a^2 / b^2 = [ 36 / 24 ]
a^2/ b^2 = 3/2
A/ B = Sqrt(3) / Sqrt(2)

your group fundraiser has a goal of $75 to pay for a new piece of equipment. you are selling pencils () for $0.50 and bracelets () for $1.00.
Answers
To reach your fundraising goal of $75, you will need to sell 150 pencils for $0.50 each and 0 bracelets for $1.00 each.
To reach your fundraising goal of $75, you can sell pencils for $0.50 and bracelets for $1.00.
1. Calculate the total amount of money needed to reach the goal:
Goal amount = $75
2. Determine the number of pencils and bracelets you need to sell to reach the goal:
Let's assume you sell x number of pencils and y number of bracelets.
The amount raised from selling pencils = x * $0.50
The amount raised from selling bracelets = y * $1.00
The total amount raised from both items should be equal to the goal amount:
x * $0.50 + y * $1.00 = $75
3. Simplify the equation:
0.50x + 1.00y = 75
4. Solve for one variable in terms of the other:
Let's solve for x in terms of y:
0.50x = 75 - 1.00y
x = (75 - 1.00y) / 0.50
5. Substitute the value of x into the equation:
(75 - 1.00y) / 0.50 * 0.50 + y * $1.00 = $75
75 - 2y + y = 75
-y = 0
y = 0
6. Find the value of x:
x = (75 - 1.00 * 0) / 0.50
x = 75 / 0.50
x = 150
To reach your fundraising goal of $75, you will need to sell 150 pencils for $0.50 each and 0 bracelets for $1.00 each.

Proving the Parallelogram Side Theorem(PLEASE HELP ASAP)
Answers
Triangles ABC and CDA are similar so ,AB≈CD and BC≈DA
how to prove parallelograms sides are similar ?We need to make use of the properties of parallelograms in order to demonstrate that BC and AB are both equal to DA and CD.
Since ABCD is a parallelogram, we know that:
Opposite sides are parallel: AB || CD and BC || DA
Opposite angles are equal: ∠A = ∠C and ∠B = ∠D
Consecutive angles are supplementary: ∠A + ∠B = 180° and ∠B + ∠C = 180°
Using these properties, we can prove that AB is equal to CD and BC is equal to DA:
Consider the triangle ABC. Since AB || CD, we have ∠A + ∠B = 180° (consecutive angles are supplementary). Similarly, in triangle CDA, we have ∠C + ∠D = 180°. Since ∠A = ∠C and ∠B = ∠D (opposite angles are equal), we have:
∠A + ∠B = ∠C + ∠D
180° = 180°
This means that triangles ABC and CDA are similar (by the Angle-Angle similarity criterion), and therefore their corresponding sides are proportional:
AB/CD = BC/DA
Since AB || CD, we can only say that AB = CD if and only if ABDC is a parallelogram with equal sides. In a similar vein, BC equals DA only when ABCD is a parallelogram with equal sides.
However, since ABCD is, by definition, a parallelogram, both AB = CD and BC = DA are correct.
In this way, we have demonstrated that Stomach muscle is equivalent to Cd and BC is equivalent to DA in the parallelogram ABCD.
