Answer:

wheres the given??

Step-by-step explanation:

I NEED THE GIVEN!!!

The choice of the type and dimensions of the measuring geometry in TPA (Thermal Performance Analysis) is influenced by several factors such as measurement accuracy, sensitivity to heat transfer variations, sample size, spatial resolution, and practical considerations.

Here are the steps to explain why the dimensions of the measuring geometry are often 25mm and 50mm probe in TPA:

Step 1: Measurement Accuracy and Resolution

The dimensions of the measuring geometry should be chosen to ensure sufficient accuracy and resolution in the measurements. Larger probe dimensions may provide more accurate results due to better averaging of temperature variations, while smaller probe dimensions can provide higher resolution for detecting localized temperature variations. Therefore, a balance needs to be struck between accuracy and resolution.

Step 2: Sensitivity to Heat Transfer Variations

The choice of probe dimensions in TPA is also influenced by the sensitivity of the system to heat transfer variations. Larger probe dimensions can capture a wider area and average out local variations, providing a more representative measurement of the overall heat transfer performance. On the other hand, smaller probe dimensions can detect localized variations and provide more detailed information about specific regions.

Step 3: Sample Size and Spatial Resolution

The dimensions of the measuring geometry should be suitable for the size and scale of the system being analyzed. If the sample size is large or if there are significant spatial variations in the heat transfer, larger probe dimensions may be more appropriate to cover a representative area. However, if the sample size is small or if there are fine-grained spatial variations, smaller probe dimensions can provide higher spatial resolution.

Step 4: Practical Considerations

Practical considerations also play a role in determining the dimensions of the measuring geometry. For instance, the size of the available equipment or probes may limit the choice of dimensions. Standardized probe sizes, such as 25mm and 50mm, are commonly used in TPA, as they are readily available and widely accepted in the industry.

The choice of the type and dimensions of the measuring geometry in TPA, such as 25mm and 50mm probes, is determined by factors such as measurement accuracy, sensitivity to heat transfer variations, sample size, spatial resolution, and practical considerations. The specific dimensions should strike a balance between accuracy and resolution, considering the characteristics of the system being analyzed and the available equipment.

Answer:

\(C(x)=108+5.5x\)

Step-by-step explanation:

Function Model

To model a real-life situation, a mathematical function can be constructed in such a way it accurately represents the variables measured in the system.

We need to build a function that represents the total monthly cost C(x) of Mary Ann's cable package. It consists of a fixed amount that includes one movie a month and a variable amount depending on the additional movies she watches. Let's call x to the additional movies, and represent the cost as a linear function of the form:

\(C(x)=C_o+bx\)

Where Co and b are to be determined with the data provided.

In the first month, Mary Ann watched 5 additional movies and paid $135.50. This gives us an ordered pair (5,135.50). Substituting into the general function:

\(135.50=C_o+5b\qquad \qquad[1]\)

In the second month, Mary Ann watched 9 additional movies and paid $157.50. The point (9,157.50) is also used in the function:

\(157.50=C_o+9b\qquad \qquad[2]\)

Subtracting [2] and [1]:

\(157.50-135.50=4b=22\)

Solving for b:

\(b=5.5\)

Using this value in [1]:

\(135.50=C_o+5*5.5=C_o+27.50\)

Solving for Co:

\(C_o=135.50-27.50=108\)

The function that  represents the total monthly cost C(x) of Mary Ann's cable package is:

\(\boxed{C(x)=108+5.5x}\)

Answer:

angle 2 would be 22

Step-by-step explanation:

The condition for a portfolio to be self-financing in the Black-Scholes model is that the portfolio's value does not change due to trading (buying or selling) costs or external cash flows. In other words, the portfolio's value remains constant over time, excluding the effects of the underlying assets' price changes.

For the given portfolio, a = -t (units of the stock) and b = S_t (units of the savings account). To determine if this portfolio is self-financing, we need to check if its value remains constant over time. Using Ito's lemma, we can express the value of the portfolio as:

d(Vt) = a_t * d(St) + b_t * d(Ct)

Substituting the values of a and b, we have:

d(Vt) = -t * (2St * dt + 4St * dBt) + S_t * d(t)

Simplifying this expression, we get:

d(Vt) = -2tSt * dt - 4tSt * dBt + S_t * dt

The portfolio is self-financing if d(Vt) = 0. However, in this case, we can see that the terms involving dBt do not cancel out, indicating that the portfolio is not self-financing.

Girsanov's theorem states that under certain conditions, it is possible to transform a Brownian motion under the real-world measure into a Brownian motion under an equivalent martingale measure (EMM). The EMM is a probability measure under which the discounted asset prices are martingales. By applying Girsanov's theorem or alternative techniques, we can derive the expression for St, the stock price, under the EMM. Unfortunately, without further information or specifications, it is not possible to provide the specific expression in this case.

To determine the price Ct of the call option on the stock at time t ≤ 2, with an exercise price K = 1 and expiration date T = 2, additional information or an appropriate result is required.

Answer:

x = 11.375

y = 23.75

Step-by-step explanation:

Corresponding angles:  A pair of angles that are in the same relative position at each point where a straight line intersects two other straight lines.

If the two lines are parallel, the corresponding angles are equal. 

Therefore:

⇒ (6x + 11)° = (3y + 8)°

⇒ 6x + 11 = 3y + 8

⇒ 6x + 3 = 3y

⇒ 3y = 6x + 3

Angles on a line sum to 180°.  

Therefore:

⇒ (3y + 8)° + (10x - 13)° = 180°

⇒ 3y + 8 + 10x - 13 = 180

⇒ 3y + 10x = 185

⇒ 3y = 185 - 10x

Substitute the first equation into the second equation and solve for x:

⇒ 6x + 3 = 185 - 10x

⇒ 16x = 182

⇒ 16x = 182

⇒ x = 11.375

Substitute the found value of x into one of the equations and solve for y:

⇒ 3y = 6(11.375) + 3

⇒ 3y = 68.25 + 3

⇒ 3y = 71.25

⇒ y = 23.75

Answer:

(a). The value of y is 6.

(b). The value of RS and ST are 33 and 31.

Step-by-step explanation:

Given that,

RS = 5y+3

ST=4y+7

RT=64

(a). We need to calculate the value of y

Using given data

\(RS+ST=RT\)

Put the value into the formula

\(5y+3+4y+7=64\)

\(9y=64-10\)

\(y=\dfrac{54}{9}\)

\(y=6\)

(b). We need to calculate the value of RS

Using equation of RS

\(RS=5y+3\)

Put the value of y

\(RS=5\times6+3\)

\(RS=33\)

We need to calculate the value of ST

Using equation of ST

\(ST=4y+7\)

Put the value of y

\(ST=4\times6+7\)

\(RS=31\)

Hence, (a). The value of y is 6.

(b). The value of RS and ST are 33 and 31.

tan 36° can be written as cot 54°, which simplifies to (√3 + 1) / (√3 - 1).

The tangent of 36° can be expressed in terms of its cofunction, which is the cotangent. The cotangent of an angle is equal to the reciprocal of the tangent of that angle. Therefore, we can rewrite tan 36° as cot (90° - 36°).

Now, cot (90° - 36°) can be simplified further. The angle 90° - 36° is equal to 54°. So, we have cot 54°.

The cotangent of 54° can be determined using the unit circle or trigonometric identities. In this case, the exact answer for cot 54° is (√3 + 1) / (√3 - 1).

Hence, tan 36° can be written as cot 54°, which simplifies to (√3 + 1) / (√3 - 1).

The percentage change in 6) real wages between 2003 and 2012 is 41.67%. 7) The rate of price inflation from year 1 to year 2 is 11.65%. 8) To maintain the same purchasing power need to earn $58,383.18 next year.

6) To calculate the percentage change in real wages, we use the formula:

Percentage Change = ((New Value - Old Value) / Old Value) * 100.

In this case, the old value (real wages in 2003) is $12, and the new value (real wages in 2012) is $17.

Plugging these values into the formula, we get ((17 - 12) / 12) * 100 ≈ 41.67%.

7) The rate of price inflation is calculated using the CPI values for year 1 and year 2.

We use the formula: Inflation Rate = ((New CPI - Old CPI) / Old CPI) * 100.

Given the CPI values of 206 for year 1 and 230 for year 2, the inflation rate is ((230 - 206) / 206) * 100 ≈ 11.65%.

8) To find out how much money you need to earn next year to maintain the same purchasing power as the current year, we adjust the current salary based on the CPI change.

find the CPI change: (214 - 206) / 206 = 0.0388.

multiply this by the current salary: $57,000 * 0.0388 ≈ $2,383.18.

we add this amount to the current salary to get the required salary for next year: $57,000 + $2,383.18 ≈ $58,383.18.

The selling price should be $9054.61 to recoup the income that the rental company loses by selling the equipment "early."

a) It is an annuity due problem.

An annuity due is a sequence of payments, made at the start of each period for a fixed period.

For instance, rent on a property, which is usually paid in advance at the start of the month and continues for a set period, is an annuity due.

In an annuity due, each payment is made at the start of the period, and the amount does not change over time since it is an agreed-upon lease agreement.

Now, the selling price can be calculated using the following formula:

\(PMT(1 + i)[\frac{1 - (1 + i)^{-n}}{i}]\)

Here,

PMT = Monthly

Rent = $200

i = Rate per period

= 4.4% per annum/12

n = Number of Periods

= 4.5 * 12 (since 4 and a half years of useful life are left).

= 54

Substituting the values in the formula, we get:

\($$PMT(1+i)\left[\frac{1-(1+i)^{-n}}{i}\right]$$$$=200(1+0.044/12)\left[\frac{1-(1+0.044/12)^{-54}}{0.044/12}\right]$$$$=200(1.003667)\left[\frac{1-(1.003667)^{-54}}{0.00366667}\right]$$$$= 9054.61$$\)
