Answer:
The second company should get the contract.
Question
The project manager for the state department of highways has two beds for the resurfacing of a 10 mile stretch of highway.
Reason
Based on the least expensive price per mile per year, the second company should get the contract. This is because the price per mile per year for the second company is lower than the price per mile per year for the first company.
The first company gives a bit of $120,000 per mile and will guarantee the web for eight years. The second company bids the word for $150,000 per mile using a new asphalt material made from used tires.
The second company will guarantee the work for 12 years. Determine the price per mile per year for each company and decide which company should get the contract based on the least expensive price per mile per year.
The project manager for the state department of highways has two beds for the resurfacing of a 10 mile stretch of highway. The first company gives a bit of $120,000 per mile and will guarantee the web for eight years.
The second company bids the word for $150,000 per mile using a new asphalt material made from used tires. The second company will guarantee the work for 12 years.
Determine the price per mile per year for each company and decide which company should get the contract based on the least expensive price per mile per year
To determine the price per mile per year for each company, we need to divide the total price by the number of years. For the first company, this would be $120,000 / 8 = $15,000 per mile per year. For the second company, it would be $150,000 / 12 = $12,500 per mile per year.
Based on these calculations, the second company offers the least expensive price per mile per year, at $12,500 per mile per year. Therefore, the project manager should choose the second company to receive the contract.

if it includes some but not all of its limit points, it is not closed and not open.(i) ∩ n∈N(0, n1)Firstly, let's find the intersection of all the sets:
∩ n∈N(0, n1)= {x∈X|∀n∈N, x∈(0,n1)}= {x∈X| 0
(i) ∩ n∈N(0, n1) is closed and not open and convex.

(iii) ∩ n∈1k(0,1+ n1) for some k∈N is both closed and open and convex.
(iv) (0, n1) for some n∈N is open and not closed and convex.
Discussion:Let X be a set, and d be a distance function on X.
Then,
(X, d) is called a metric space if it fulfills the following conditions:∙For each x, y∈X, d(x, y)≥0, and d(x, y)=0 if and only if x=y.
For each x, y∈X, d(x, y)=d(y, x).∙For each x, y, z∈X, d(x, y)≤d(x, z)+d(z, y).Thus, let X=[0,1] with Euclidean metric d(x,y)=|x−y| for x,y∈X.
Then, the distance between two points on a line is calculated using the Euclidean distance. For example, the distance between 0 and 1 on [0, 1] is 1.
The distance between 1/2 and 3/4 on [0, 1] is 1/4.Convex: If two points lie within the same set, then a set is known to be convex.Closed and open:
If the set includes its limit points, the set is closed. If a set includes none of its limit points, it is open.
Therefore, if it includes some but not all of its limit points, it is not closed and not open.(i) ∩ n∈N(0, n1)Firstly, let's find the intersection of all the sets:

MY NOTES ASK YOUR TEACHER PRACTICE ANOTHER The monthly demand function for a product sold by a monopoly is p = 2,096 - 1x2 dollars, and the average cost is C = 900 + 20x + x2 dollars.

P(x) = (a) Find P'(x) P'(x) = Considering the limitations of production, find the quantity (in hundreds of units) that will give the maximum profit. hundred units (b) Find the maximum profit. (Round your answer to the nearest cent.)
Answers
The maximum profit is approximately $173,023.32. First, we need to find the revenue function, which is given by:
R(x) = xp(x)
where p(x) is the price function. We are given that:
p(x) = 2096 - x^2
Therefore, the revenue function is:
R(x) = x(2096 - x^2) = 2096x - x^3
Next, we need to find the cost function, which is given by:
C(x) = 900 + 20x + x^2
Finally, the profit function is given by:
P(x) = R(x) - C(x) = (2096x - x^3) - (900 + 20x + x^2) = -x^3 + 2076x - 900 - x^2
To find the maximum profit, we need to find the critical points of P(x), which occur when P'(x) = 0. We have:
P'(x) = -3x^2 + 2076 - 2x
Setting P'(x) = 0 and solving for x, we get:
-3x^2 + 2076 - 2x = 0
3x^2 - 2x + 2076 = 0
Using the quadratic formula, we get:
x = [-(-2) ± sqrt((-2)^2 - 4(3)(2076))]/(2(3)) ≈ 19.47, -35.94
Since production is limited to 1000 units, we can only consider the positive root, x ≈ 19.47. Therefore, the quantity that will give the maximum profit is 1947 hundred units.
To find the maximum profit, we evaluate P(x) at x = 19.47:
P(19.47) = -(19.47)^3 + 2076(19.47) - 900 - (19.47)^2 ≈ $173,023.32
Therefore, the maximum profit is approximately $173,023.32.
Note: It is important to check that this is indeed a maximum by verifying that the second derivative of P(x) is negative at x = 19.47. This is left as an exercise for the reader.

if 180 liters of fluid enter the kidneys each day, about how much fluid will be reabsorbed? 178 liters 100 liters 50 liters 2 liters
Answers
If 180 liters of fluid enter the kidneys each day, about 178 liters of fluid will be reabsorbed by the kidneys each day.
The kidneys play a crucial role in filtering and regulating fluid balance in the body. On average, approximately 180 liters of fluid enter the kidneys each day through the process of filtration. However, not all of this fluid is excreted as urine. The majority of it, around 99%, is reabsorbed back into the bloodstream.
The reabsorption process occurs in the renal tubules, where essential substances such as water, electrolytes, and nutrients are selectively transported back into the bloodstream while waste products and excess substances are removed for eventual excretion.
Therefore, out of the initial 180 liters that enter the kidneys, around 178 liters are reabsorbed, leaving only a small amount (approximately 2 liters) to be excreted as urine.

Answers
when x = 0, a = -2, so we can substitute these values to get: of k is -5.
how to find the question ?
First, we need to find the equation of each function. The general equation of an exponential function is f(x) = a(b)ˣ, where "a" is the initial value and "b" is the base.
For function g, we can see that it declines through the given points, which means that its base is between 0 and 1. We also know that when x = -2, f(-2) = 5, so we can write:
5 = a(b)⁻²
Similarly, when x = -1, f(-1) = 0, so:
0 = a(b)⁻¹
Dividing the second equation by the first, we get:
0/5 = (a(b)⁻¹) / (a(b)⁻²)
0 = b
Therefore, the equation of g is:
g(x) = a(0)ˣ = a
Now, for function f, we can see that it also declines through the given points, so its base is also between 0 and 1. Using the same method as above, we can find that its equation is:
f(x) = 3(1/2)ˣ
Since we know that g(x) = f(x) + k, we can substitute the equations of g and f to get:
a = 3(1/2)ˣ+ k
We also know that when x = 0, a = -2, so we can substitute these values to get:
-2 = 3(1/2)⁰ + k
-2 = 3 + k
k = -5
Therefore, the value of k is -5.

What is addition?Addition is a mathematical operation that combines two or more numbers to create a new, larger number. The result of an addition operation is called the sum. Addition is typically denoted by the plus sign (+), and the numbers being added are called addends. Addition is a basic arithmetic operation and is used extensively in mathematics. It is one of the four basic operations, along with subtraction, multiplication, and division. Addition is commutative, meaning that the order in which the addends are added does not affect the sum.

These discussions take a long time and subsequently, the original rates proposed by the Contractor are agreed. By this time, the additional works are completed. The Engineer proceeds to certify on the basis of the agreed rates. On the basis of the agreed rates, the Engineer becomes aware that the resulting additional cost is beyond his limit of authority provided for in the Contract. He therefore proceeds to seek for the approval of the additional cost from the Employer copying his correspondence to the Contractor.

Angles 3 and 6 are consecutive exterior angles, and those are supplementary, meaning that they add up to 180 degrees. 1 and 5 are the same way
Angles 2 and 8 are consecutive interior angles, and those are also supplementary. angles 7 and 4 are the same way.
Angles 7 and 2 and 8 and 4 you can see those are crossing on the inside, those are called alternate interior angles, and these angles are congruent to one another. meaning that 7 and 2 are congruent to one another, and 8 and 4 are also congruent, or equal to one another
Angles 3 and 5 and 1 and 6 are what as known as Alternate Exterior Angles. Those angles are on the outside part of the intersection and they are congruent if cut by a transversal. meaning that 3 and 5 are equal to one another and so is 1 and 6.

Answer:
y = 8
Step-by-step explanation:
The line that contains points (0, 8) and (8, 8) is a horizontal line in which every point has 8 as its y-coordinate.
Equation: y = 8
y=-1/2x+1 is the equation that represents a line that passes through points (-6, 4) and (2,0)
What is Slope of Line?The slope of the line is the ratio of the rise to the run, or rise divided by the run. It describes the steepness of line in the coordinate plane.
The slope intercept form of a line is y=mx+b, where m is slope and b is the y intercept.
The slope of line passing through two points (x₁, y₁) and (x₂, y₂) is
m=y₂-y₁/x₂-x₁
the equation of a line that contains the points (0,8) and (8,8)
Slope=0
We need to find the y intercept
8=b
y=8 is the equation of a line that contains the points (0,8) and (8,8)
Now let us find the equation that represents a line that passes through points (-6, 4) and (2,0).
m=0-4/2+6
=-1/2
Now find the y intercept
0=2(-1/2)+b
b=1
y=-1/2x+1 is the equation that represents a line that passes through points (-6, 4) and (2,0),
Hence, y=-1/2x+1 is the equation that represents a line that passes through points (-6, 4) and (2,0)
