Which of the following matrices are elementary? For those that are, state which type it is, and give its inverse. (a) E1=⎝010100001⎠(b) E2=⎝110020001⎠(c) E3=⎝400010001⎠d) E4=⎝100010501⎠(e) E5=⎝103012001⎠
The elementary matrices are E1, E3, E4, and E5, and their inverse matrices are E1^(-1), E3^(-1), E4^(-1), and E5^(-1), respectively.
An elementary matrix is a square matrix that can be obtained from the identity matrix by performing a single elementary row operation.
(a) E1 = 010100001 is an elementary matrix of type 1, because it is obtained from the identity matrix by interchanging the first and second rows. Its inverse is also of type 1, and is obtained by interchanging the first and second rows: E1^(-1) = 010100001.
(b) E2 = 110020001 is not an elementary matrix, because it cannot be obtained from the identity matrix by performing a single elementary row operation.
(c) E3 = 400010001 is an elementary matrix of type 1, because it is obtained from the identity matrix by adding 4 times the first row to the second row. Its inverse is also of type 1, and is obtained by adding -4 times the first row to the second row: E3^(-1) = 100−400001.
(d) E4 = 100010501 is an elementary matrix of type 3, because it is obtained from the identity matrix by multiplying the third row by 5. Its inverse is also of type 3, and is obtained by multiplying the third row by 1/5: E4^(-1) = 100010120.
(e) E5 = 103012001 is an elementary matrix of type 2, because it is obtained from the identity matrix by multiplying the second row by 2. Its inverse is also of type 2, and is obtained by multiplying the second row by 1/2: E5^(-1) = 101012001.

Consider the following equation. 5x+3y=8 Step 1 of 2 : Determine the missing coordinate in the ordered pair (3,?) so that it will satisfy the given equation.
Answer: (3, -2.333) or (3, -7/3)
Step-by-step explanation:
We're given an x value (x=3) when looking at the coordinate, so we're trying to find what y is equal to given the equation. We can plug in x=3 into 5x+3y=8 and isolate for y.
\(5(3)+3y=8\\15 + 3y=8\\3y=-7\\y=-\frac{7}{3}\)
Answer:
y= -2 1/3
Step-by-step explanation:
Since you have x, you put x into the equation and work through the problem.
5(3)+3y=8
15+3y=8, then subtract 15 from both sides
3y=(-7), then divide both sides by 3
y=(-7)/3 or (-2 1/3)
Match each function on the left to all points on the right that would be located on the graph of the function. Help!! thanks
Each function on the left should be matched to all points on the right that would be located on the graph of the function as follows;
f(x) = 2x + 2 ⇒ (0, 2).
f(x) = 2x² - 2 ⇒ (-1, 0).
\(f(x) = 2\sqrt{x+1}\) ⇒ (0, 2).
What is a function?In Mathematics and Geometry, a function is a mathematical equation which defines and represents the relationship that exists between two or more variables such as an ordered pair in tables or relations.
Next, we would determine the point or ordered pair that represent a solution on the graph of each of the function as follows;
For the ordered pair (0, 2), we have:
f(x) = 2x + 2
2 = 2(0) + 2
2 = 2 (True).
For the ordered pair (-1, 0), we have:
f(x) = 2x² - 2
0 = 2(-1)² - 2
0 = 2 - 2
0 = 0 (True).
For the ordered pair (0, 2), we have:
\(f(x) = 2\sqrt{x+1}\\\\2= 2\sqrt{0+1}\\\\2 = 2\sqrt{1}\)
2 = 2 (True).

Dado cot B = 0.57736, determina la medida del ángulo B.
The measure of angle B is approximately equal to 56.31 degrees, rounded to two decimal places.
What is a angle measure?An angle measure is a numerical value that represents the amount of rotation between two intersecting lines, line segments or rays. It is typically measured in degrees, although other units of measurement such as radians and grads may also be used. The size of an angle can range from 0 degrees (corresponding to no rotation or a straight line) to 360 degrees (corresponding to a full rotation). In geometry, angles are used to describe the relationships between lines and shapes, and are an important concept in fields such as trigonometry and calculus.
To find the measure of angle B given cot B = 0.57736, we can use the inverse tangent function.
The tangent of an angle is the ratio of the opposite side to the adjacent side,
So cot B = adjacent side / opposite side.
By taking the inverse tangent of both sides and substituting cot B for adjacent side / opposite side, we arrive at the equation
B = arctan(cot B).
Evaluating arctan(cot B) using a calculator gives us the measure of angle B as,
B = arctan(cot B) = 56.31° (rounded to two decimal places)

The transformation in this problem is a translation combined with a reflection, hence yes, it is a rigid motion, as the side lengths of the transformed figure are equal to the side lengths of the original figure.
What are transformations on the graph of a function?Examples of transformations are given as follows:
Translation: Translation left/right or down/up.Reflections: Over one of the axes or over a line.Rotations: Over a degree measure.Dilation: Coordinates of the vertices of the original figure are multiplied by the scale factor.The dilation is the only transformation that is not a rigid motion, as it changes the side lengths of the figure.
The transformation for this problem has the rule defined as follows:
(x,y) -> (x + 2, -y).

I don't know the method to find the equations of the other 2 ides. Can someone please explain step by step how to do this.
The equations of the other two sides are AD: y = -3x + 3 and DC: y = 1/2x - 1/2.
What is point-slope form?
The point-slope form is a way to write the equation of a straight line in algebra. It is used when you know the coordinates of a point on the line and the slope of the line. The point-slope form of a linear equation is:
y - y₁ = m(x - x₁)
where m is the slope of the line, and (x1, y1) are the coordinates of a point on the line.
Since AB and BC are two sides of a parallelogram, they are parallel to each other. Thus, we can use the slope formula to find the slopes of these sides.
Slope of AB:
m = (y₂ - y₁)/(x₂ - x₁)
= (6 - 3)/(6 - 0)
= 3/6
= 1/2
Slope of BC:
m = (y₂ - y₁)/(x₂ - x₁)
= (3 - 6)/(7 - 6)
= -3/1
= -3
Now that we know the slopes of AB and BC, we can use the point-slope form to find the equations of the other two sides.
Equation of AD:
We know that AD is parallel to BC and passes through point A. So, we can use the point-slope form with the slope of BC and point A.
y - y₁ = m(x - x₁)
y - 3 = -3(x - 0)
y - 3 = -3x
y = -3x + 3
Equation of DC:
We know that DC is parallel to AB and passes through point C. So, we can use the point-slope form with the slope of AB and point C.
y - y₁ = m(x - x₁)
y - 3 = 1/2(x - 7)
y - 3 = 1/2x - 7/2
y = 1/2x - 1/2
Therefore, the equations of the other two sides are:
AD: y = -3x + 3
DC: y = 1/2x - 1/2

Answer:
(a) The average number of passengers that will be on each flight is 28.8.
(b) Everyone will have a seat on about 84.4% of the flights.
Step-by-step explanation:
The correct question is:
Suppose that past experience shows that about 10% of passengers who are schedule to take a particular flight fail to show up. For this reason, airlines sometimes overbook flights, selling more tickets than they have seats, with the expectation that they will have some no shows. Suppose an airline used a small jet with seating for 30 passengers on a regional route and assume that passengers are independent of each other in whether they show up for the flight. Suppose that the airline consistently sells 32 tickets for every one of these flights.
(a) On average, how many passengers will be on each flight?
(b) How often will they have enough seats for all of the passengers who show up for the flight?
Solution:
Let the random variable X measure the number of passengers (out of 32) who show up for a flight.
For each passenger there is a 90% chance of showing up, so X is a binomial random variable with n = 32 and p = 0.90.
(a)
The average of a binomial random variable is:
\(\text{Average}=np\)
Compute the average number of passengers that will be on each flight as follows:
\(\text{Average}=np\)
\(=32\times 0.90\\=28.8\)
Thus, the average number of passengers that will be on each flight is 28.8.
(b)
To have enough seats for all of the passengers who show up for the flight, the value of X must be less than or equal to 30.
Compute the value of P (X ≤ 30) as follows:
P (X ≤ 30) = 1 - P (X > 30)
= 1 - P (X = 31) - P (X = 32)
\(=1-[{32\choose 31}\ (0.90)^{31}\ (1-0.90)^{32-31}]-[{32\choose 32}\ (0.90)^{32}\ (1-0.90)^{32-32}]\\\\=1-0.122087-0.034337\\\\=0.843576\\\\\approx 0.844\)
Thus, everyone will have a seat on about 84.4% of the flights.

Two integers are relatively _________ if and only if their only common positive integer factor is 1.
Answer:
Two integers are relatively primes if and only if their only common positive integer factor is 1.
Step-by-step explanation:
The prime number is one whose only divisor is 1 and itself.
The prime factors of a whole number are the exact prime divisors of that whole number. In other words, every composite number can be written as a multiplication of two or more prime factors.
So, two integers are relative primes if they have no prime factor in common, or, put another way, if they have no common divisor other than 1.
So, two integers are relatively primes if and only if their only common positive integer factor is 1.

d) Discuss the consequences of the imposition of a tax of 5 per unit sold in market 1 by
a) To maximize profits, 10 units should be sold in market 1 and 5 units in market 2.
b) The corresponding prices are $180 in market 1 and $160 in market 2.
c) If it becomes illegal to discriminate, the profit loss is $50.
d) The imposition of a tax of $5 per unit sold in market 1 would likely decrease the monopolist's profit and potentially lead to adjustments in prices and quantities sold in both markets.
a) To maximize profits, the monopolist should set marginal revenue equal to marginal cost in each market.
In this case, marginal revenue is equal to the derivative of the demand function with respect to quantity, and it can be calculated as MR = dP/dQ.
For market 1:
MR₁ = dP₁/dQ₁ = -2
For market 2:
MR₂ = dP₂/dQ₂ = -4
Setting MR equal to marginal cost, which is the derivative of the cost function with respect to quantity, gives:
MR₁ = -2 = dC/dQ₁ = 20
MR₂ = -4 = dC/dQ₂ = 20
Solving these equations, we find:
Q₁ = 10
Q₂ = 5
Therefore, the monopolist should sell 10 units in market 1 and 5 units in market 2 to maximize profits.
b) To determine the corresponding prices, we substitute the quantities obtained in part (a) into the demand functions:
For market 1:
P₁ = 200 - 2Q₁ = 200 - 2(10) = 180
For market 2:
P₂ = 180 - 4Q₂ = 180 - 4(5) = 160
Therefore, the corresponding prices are $180 in market 1 and $160 in market 2.
c) To calculate the profit lost if it becomes illegal to discriminate, we need to compare the profits under discrimination with the profits under non-discrimination.
Under discrimination, the monopolist charges different prices in each market, while under non-discrimination, the same price is charged in both markets.
Under discrimination:
Profit = Total revenue - Total cost
For market 1:
Total revenue₁ = P₁ \(\times\) Q₁ = 180 \(\times\) 10 = $1
For market 2:
Total revenue₂ = P₂ \(\times\) Q₂ = 160 \(\times\) 5 = $800
Total revenue = Total revenue₁ + Total revenue₂ = $1800 + $800 = $2600
Total cost = C = 20(Q₁ + Q₂) = 20(10 + 5) = $300
Profit = Total revenue - Total cost = $2600 - $300 = $2300
Under non-discrimination:
Since the same price is charged in both markets, we take the average price:
Average price = (P₁ + P₂) / 2 = (180 + 160) / 2 = $170
Total revenue = Average price \(\times\) (Q₁ + Q₂) = $170 \(\times\) (10 + 5) = $2550
Total cost remains the same at $300.
Profit = Total revenue - Total cost = $2550 - $300 = $2250
Therefore, the profit lost if discrimination becomes illegal is $2300 - $2250 = $50.
d) The imposition of a tax of $5 per unit sold in market 1 would increase the cost per unit for the monopolist.
This would affect the profit-maximizing quantity in market 1 and potentially lead to a change in prices.
The monopolist would compare the new marginal cost, which includes the tax, with the marginal revenue to determine the new profit-maximizing quantities and prices.
The tax would likely reduce the monopolist's profits and could potentially result in adjustments in production and pricing strategies.
