Answer:

x(x+1)=54,Quadratic equation

The vector v1 from point O to point E is given by <Δx, Δy, Δz>.

The vector v1 from point o to point e is the directed line segment that connects point o to point e. In other words, it is the vector that starts at point o and ends at point e.

To find the vector v 1, you can subtract the coordinates of point o from the coordinates of point e. Thus, v 1 = (xe - xo)i + (ye - yo)j + (ze - zo)k, where i, j, and k are the unit vectors in the x, y, and z directions, respectively.

To find the vector v1 from point O to point E, you need to follow these steps:

Step 1: Identify the coordinates of point O and point E. Let's assume the coordinates of point O are (x1, y1, z1) and point E are (x2, y2, z2).

Step 2: Calculate the differences between the coordinates of point E and point O. Subtract the coordinates of point O from point E:
Δx = x2 - x1
Δy = y2 - y1
Δz = z2 - z1

Step 3: Represent the vector v1 from point O to point E using the differences in coordinates:
v1 = <Δx, Δy, Δz>

That's it! The vector v1 from point O to point E is given by <Δx, Δy, Δz>.

We are asked to find the area of this circle.

\(\triangle~\fbox{\bf{KEY:}}\)

→ \(\bf{Area_{circle}=\pi r^{2}}\)

Notice that we are asked to use 3.142 for \(\pi\) (pi).

The radius isn't given to us;  what we have instead is...the diameter.

To find the radius, we divide the diameter by 2.

\(\ddot\bigstar\) Remember this...

\(\fbox{\bf{To\;find\;the\;radius,\;we\;divide\;the\;diameter\;by\;2}}\)

Thus, the radius is

\(\bf{9\div2=4.5}\)

Now substitute the values (3.142 for pi and 4.5 for r):

\(\bf{A=3.142\times4.5^{2} }\)

Simplifying,

\(\bf{A=3.142\times20.25}\)

Simplifying,

\(\bf{A=63.6255\:m}\)

Rounding to 2 decimal places (D.P.):

\(\bf{A=63.63\:m}\)

The amount of the sales tax and tip is $96 and $24, then the total cost of the dinner will be $600.

The amount of something is expressed as if it is a part of the total which is a hundred. The ratio can be expressed as a fraction of 100. The word percent means per 100. It is represented by the symbol ‘%’.

Jerry took his extended family out for a dinner that cost $480. Jerry paid 5% sales tax and left a 20% tip on $480.

Then the cost of the sales tax will be

→ 0.05 × 480 = $24

Then the amount of the tip will be

→ 0.20 × 480 = $96

Then the total cost of the dinner will be

→ $24 + $96 + $480 = $600

To find the derivative of the curve given by the equation ry + sin(y)cos(x) = y², where r is a constant, we can use implicit differentiation.

Differentiating both sides of the equation with respect to x, we get: r(dy/dx) + (d/dx)(sin(y)cos(x)) = 2yy'(dy/dx). Applying the chain rule, we have: r(dy/dx) - sin(y)sin(x) - cos(y)cos(x)(dy/dx) = 2yy'(dy/dx). Rearranging the terms and factoring out dy/dx, we get: (dy/dx)(r - cos(y)cos(x)) = sin(y)sin(x) - 2yy'(dy/dx). Dividing both sides by (r - cos(y)cos(x)), we obtain the expression for the derivative: dy/dx = (sin(y)sin(x) - 2yy'(dy/dx))/(r - cos(y)cos(x)). Simplifying further, we can isolate dy/dx: dy/dx = (sin(y)sin(x))/(r - cos(y)cos(x)) - (2yy'(dy/dx))/(r - cos(y)cos(x)).

b) To find the equation of the tangent line to the curve that passes through a given point (x₀, y₀), we need to substitute the coordinates of the point into the derivative expression we obtained above. Let's assume the point is (x₀, y₀). Therefore, we have: dy/dx = (sin(y₀)sin(x₀))/(r - cos(y₀)cos(x₀)) - (2y₀y'(dy/dx))/(r - cos(y₀)cos(x₀)). Next, we substitute the values of x₀ and y₀ into the expression for dy/dx and solve for dy/dx: dy/dx = (sin(y₀)sin(x₀))/(r - cos(y₀)cos(x₀)) - (2y₀y'(dy/dx))/(r - cos(y₀)cos(x₀)).

Now, we can rearrange this equation to solve for dy/dx: (dy/dx)[1 + (2y₀)/(r - cos(y₀)cos(x₀))] = (sin(y₀)sin(x₀))/(r - cos(y₀)cos(x₀)). Finally, we can isolate dy/dx by dividing both sides: dy/dx = (sin(y₀)sin(x₀))/(r - cos(y₀)cos(x₀))[1 + (2y₀)/(r - cos(y₀)cos(x₀))]. This expression gives the value of the derivative dy/dx at the point (x₀, y₀), which represents the slope of the tangent line to the curve at that point.

The DWL falls when the monopolist receives the subsidy because it leads to an increase in output and a decrease in price.

The cost function and demand function of a monopolist can be found in the question. These can be used to derive the marginal revenue and marginal cost.

The optimal level of output and profit can be derived using the marginal revenue and marginal cost equations. After that, you can confirm that the demand is elastic at the optimal output.

After that, you need to calculate the markup and the DWL associated with the monopoly output. Finally, you need to find the new optimal output and determine if the DWL increases or decreases.

Given:Cost Function C(Q) = ¼ Q2 Marginal cost MC(Q) = ½ Q Demand P = 100 – ¼ Q. a.

Sketch the market demand, marginal costs, and marginal revenues.

Market demand:Marginal cost:Marginal revenue: b. What is the monopolist’s optimal level of output and profits?In the monopolistic market, the optimal level of output and profits are given by the condition that Marginal Revenue = Marginal Cost.

Marginal Revenue is the derivative of Total Revenue with respect to Quantity, which can be found by using the demand equation and solving for Q:TR(Q) = P × Q = (100 – ¼ Q)Q = 100Q – ¼ Q2MR(Q) = dTR(Q)/dQ = 100 – ½ QMarginal Cost is given by the question as MC(Q) = ½ Q.

The monopolist's optimal level of output and profits can be found by equating MR and MC:100 – ½ Q = ½ Q => Q = 66.67 units of outputWhen Q = 66.67, the price is given by the demand equation:P = 100 – ¼ Q => P = 83.33.

Therefore, the monopolist's optimal output is 66.67 and optimal profits are (P – MC) × Q = (83.33 – 33.33) × 66.67 = $2,000.

Confirm that demand is elastic at the optimal output.The demand is elastic at the optimal output if the absolute value of the price elasticity of demand is greater than one.

The price elasticity of demand is given by:Ed = (% Change in Quantity Demanded)/(% Change in Price) = (dQ/Q)/(dP/P) × P/QSince MR = P(1 - 1/Ed), MR is greater than MC if Ed is less than 1 and less than MC if Ed is greater than 1. Therefore, the optimal output occurs where Ed is equal to
Substituting the values of P and Q, we get:Ed = (dQ/Q)/(dP/P) × P/Q = -1.47Therefore, demand is elastic at the optimal output.

Calculate the firm’s markup.The markup is given by the formula (P - MC)/P.Substituting the values of P and MC, we get:(83.33 - 33.33)/83.33 = 0.6 = 60% markup .

What is the DWL associated with the monopoly output?DWL (Deadweight Loss) is the difference between the total surplus in a competitive market and the total surplus in a monopoly market.

The formula for DWL is:DWL = (1/2)(Pmon - Pcomp)(Qcomp - Qmon)DWL can be calculated by using the demand equation and finding the quantity demanded at the monopoly price and the competitive price. At the monopoly price of $83.33, the quantity demanded is 66.67.

At the competitive price of $66.67, the quantity demanded is 100. Therefore, DWL can be calculated as follows:DWL = (1/2)(83.33 - 66.67)(100 - 66.67) = $1,111.1 f.

Suppose the government offered a $10 production subsidy to the monopolist. What is their new optimal output?The new optimal output will be where the new marginal cost equals the original marginal revenue.

The subsidy reduces the marginal cost to (1/2) Q - $10.

Therefore, the monopolist's new optimal output can be found by solving for Q:100 - 1/2 Q + 10 = 1/2 Q => Q = 74.07 units of outputWhen Q = 74.07, the price is given by the demand equation:P = 100 - 1/4 Q => P = $81.48 g. Does the DWL fall or rise?The DWL falls when the monopolist receives the subsidy because it leads to an increase in output and a decrease in price.

Therefore, the deadweight loss falls.

Answer: |81-x|<5

Step-by-step explanation:

Given: Temperature of an enclosure for a pet corn snake should be an average of 81° F.

Temperature in the enclosure should not vary by more than 5° F.

Let x= Temperature in the enclosure

Then, difference between average and current temperature should less the 5.

i.e. |81-x|<5     (required absolute value equation  )

hence, the absolute value equation could be used to determine the minimum and maximum temperatures recommended for the corn snake enclosure:

|81-x|<5

Using absolute value, it is found that the equation that could be used to determine the minimum and maximum temperatures recommended for the corn snake enclosure is:

\(|T - 81| = 5\)

\(|x| = x, x \geq 0\)

\(|x| = -x, x < 0\)

In this problem, the temperature T should be within 5º F of 81ºF, hence, the absolute value of the difference between T and 81 should be of 5, that is:

Step-by-step explanation:

In India, the first step towards criminal proceeding is an investigation by the police. The investigation is the exclusive domain of the police and can not be curtailed in normal circumstances. The main purpose of an investigation is the identification of the offender so as to serve him with punishment for the crime done by him in accordance with the provisions contained under law. According to Section 156 of the Code of Criminal Procedure, the police have unfettered powers to investigate into a cognizable offence. The term cognizable offence is any act or omission committed by a person under any law in force which is punishable and is considered to be a crime. The police have the authority to arrest any person who has committed a cognizable offence. Beside Criminal investigation, there are other types of investigations which become the part of the life of an investigator. Some of the types of investigation are as follows:

Civil investigation: These are the investigations which are carried on during the civil suits in which violation of law is generally not included and the question of money or property is to be settled;

Negligence investigation: These types of investigations are conducted either by the plaintiff’s counsel to prove the liability of the defendant or by the defendant’s attorney to refute the claims of the plaintiff. It is accomplished by the use of surveillance, interviewing the witnesses;

Corporate investigation: In Corporate investigations the investigator monitors the business of the company and also provides the information about the fraud within or outside the company;

General investigation: It is like an umbrella term including a great variety of investigative activities. These activities may be conducted for different purposes like the determination of the location of witnesses, dishonest employees, fraud etc.

The parent function of a quadratic is y = x^2.

To translate it into 3 units right, we need to subtract 3 from x inside the parentheses: y = (x-3)^2.
To reflect the function across the x-axis, we need to negate the entire function: y = -(x-3)^2.
