**Apologies** for the confusion in the previous response. Let's correct it and find the first three terms of the **Maclaurin series** for F(x) = ln((x+3)(x+3)²).

To find the Maclaurin series expansion, we need to calculate the derivatives of F(x) and evaluate them at x = 0 since it is a Maclaurin series centered at zero.The first **derivative** of F(x) can be found using the chain rule:F'(x) = (1/((x+3)(x+3)²)) * (2(x+3)(x+3) + 2(x+3)²)

Simplifying this expression gives:F'(x) = (2(x+3) + 2(x+3)) / ((x+3)(x+3)²)

= (4(x+3)) / ((x+3)(x+3)²)

= 4 / (x+3)

Now, let's find the second derivative by **differentiating** F'(x):

F''(x) = -4 / (x+3)²

Finally, we'll find the third derivative by differentiating F''(x):

F'''(x) = 8 / (x+3)³

To obtain the Maclaurin series, we substitute these derivatives into the **general formula**:F(x) = F(0) + F'(0)x + (F''(0)/2!)x² + (F'''(0)/3!)x³ + ...

Substituting the values we found:F(0) = ln((0+3)(0+3)²) = ln(27)

F'(0) = 4 / (0+3) = 4/3

F''(0) = -4 / (0+3)² = -4/9

Thus, the first three terms of the Maclaurin series for F(x) = ln((x+3)(x+3)²) are:F(x) ≈ ln(27) + (4/3)x - (4/9)x² + ...Apologies

The average sugar content of navel oranges is around 11.3 grams. A random sample of 6 navel n=6 oranges yielded a mean sugar content of 8.5g and a standard deviation of 0.975g (estimated from maximum and minimum values). At the 5% significance level test the claim that the average sugar content of navel oranges is less than 11.3g. We assume a normal distribution for the sugar content of navel oranges. State the two opposing hypotheses and clearly indicate which one is the claim.

The two opposing hypotheses are: H0, Null **hypothesis** is average sugar content of navel oranges is 11.3g or more and HA, Alternative hypothesis is the** average** sugar content of navel oranges is less than 11.3g

In this** hypothesis** test, we are testing the claim that the average sugar content of navel oranges is less than 11.3 grams. We set up the following null and alternative hypotheses:

H0 (Null hypothesis): The average sugar content of navel oranges is 11.3g or more.

HA (Alternative hypothesis): The average sugar content of navel oranges is less than 11.3g (claim).

To test these hypotheses, we calculate the test** statistic **using the given sample data. The sample mean sugar content is 8.5g, and the standard deviation is estimated to be 0.975g. Since the sample size is small (n = 6) and the population standard deviation is unknown, we can use the t-distribution.

Using the** t-distribution **and the given sample data, we calculate the test statistic t-value. We then compare the calculated t-value with the critical t-value at the 5% significance level and determine whether to reject or fail to reject the null hypothesis.

If the calculated** t-value **is less than the critical t-value, we reject the null hypothesis and conclude that there is sufficient evidence to support the claim that the average sugar content of navel oranges is less than 11.3g. On the other hand, if the calculated t-value is greater than the critical t-value, we fail to reject the null hypothesis and do not have enough evidence to support the claim.

3)Solve the equation below

coshz=-2

The solution for coshz = -2 is z = ln(-2 + sqrt(3)) and z = ln(-2 - sqrt(3)) after checking if the equation is **integer**.

1. Check if the equation is integer

f(z) = coshx.cosy + isechx.secy

Given that, f(z) = coshx.cosy + isechx.secy

Now we can see that the given **function** f(z) is not an integer function.

2. Solve the equation below

coshz = -2coshz is a hyperbolic cosine function defined as,

coshz = (ez + e-z) / 2

Therefore, coshz = -2 can be written as:

ez + e-z = -4

Now let's multiply both sides of the equation by e^z to simplify the equation.

e2z + 1 = -4e^z

Then, substituting x = e^z into the equation gives us the following:

x² + 4x + 1 = 0

By using the **quadratic **formula, we can solve for x:

x = (-b ± sqrt(b² - 4ac)) / 2a where a = 1, b = 4 and c = 1.

x = (-4 ± sqrt(4² - 4(1)(1))) / 2(1)x = (-4 ± sqrt(16 - 4)) / 2x = (-4 ± sqrt(12)) / 2x = -2 ± sqrt(3)

Therefore, the solution for coshz = -2 is z = ln(-2 + sqrt(3)) and z = ln(-2 - sqrt(3)).

Part 3 of 5 (c) n=4, p=0.21, X=3 P(X) = _______

The **value** of P(X = 3) is 0.02923.

To find P(X) for the given values n = 4, p = 0.21, and X = 3, we can use the **probability mass function** (PMF) of the binomial distribution.

The PMF of the **binomial distribution** is given by:

P(X) = [tex]C_X^n * p^X * (1 - p)^{(n - X)[/tex]

where C (n, X) is the binomial coefficient, given by n! / (X! * (n - X)!), representing the number of ways to choose X successes out of n trials.

Substituting the values into the **formula**, we have:

P(X = 3) = (C (4, 3) * (0.21)³ * (1 - 0.21)⁽⁴⁻³⁾

Calculating the binomial coefficient:

(C(4, 3)) = 4! / (3! * (4 - 3)!) = 4

Substituting the values into the formula:

P(X = 3) = 4 * (0.21³) * (0.79¹)

Calculating the result:

P(X = 3) = 4 * 0.009261 * 0.79

P(X = 3) ≈ 0.02923

A clothing designer determines that the number of shirts she can sell is given by the formula S = −4x2 + 80x − 76, where x is the price of the shirts in dollars. At what price will the designer sell the maximum number of shirts? a $324 b $19 c $10 d $1

To find the price at which the designer will sell the maximum number of shirts, we need to determine the vertex of the quadratic function representing the number of shirts sold.

The equation for the number of shirts sold is given by:

S = -4x^2 + 80x - 76

This is a quadratic function in the form of:

S = ax^2 + bx + c

To find the price at which the maximum number of shirts is sold, we need to locate the vertex of the quadratic function. The x-coordinate of the vertex can be found using the formula:

x = -b / (2a)

In this case, a = -4 and b = 80. Plugging in these values, we can calculate the x-coordinate:

x = -80 / (2*(-4))

x = -80 / (-8)

x = 10

Therefore, the designer will sell the maximum number of shirts at a price of $10. Hence, the correct option is c) $10.

Round the answers to two decimal places. A 99.9% confidence interval for the mean number of years of education is

To construct a 98% confidence **interval **for the true mean length of all Foreign Language movies made since 2000, we can use the formula:

Confidence Interval = sample mean ± (**critical value * standard error**)

First, we need to calculate the standard error, which is given by the formula:

Standard Error = standard deviation / √(sample size)

Given:

Sample mean () = 110.8 minutes

Standard **deviation **(σ) = 14.5 minutes

Sample size (n) = 44

**Standard Error** = 14.5 / √44 ≈ 2.184

Next, we need to find the **critical value** for a 98% confidence level. Since the sample size is large (n > 30), we can use the Z-distribution. The critical value for a 98% confidence level is approximately 2.33.

Now, we can calculate the confidence interval:

Confidence Interval = 110.8 ± (2.33 * 2.184)

Confidence **Interval **≈ (105.9, 115.7)

Therefore, the 98% confidence interval for the true **mean length** of all Foreign Language movies made since 2000 is approximately 105.9 to 115.7 minutes.

Given f(x,y)=sin(x+y) where x=s4t3,y=4s−3t. Find

fs(x(s,t),y(s,t))

ft(x(s,t),y(s,t))

The **partial derivative** fs(x(s,t),y(s,t)) is equal to cos(x(s,t) + y(s,t)) * (4s^3t^3 - 12s^-4t), and ft(x(s,t),y(s,t)) is equal to cos(x(s,t) + y(s,t)) * (12s^4t^2 - 12s^-3).

To find fs(x(s,t),y(s,t)) and ft(x(s,t),y(s,t)), we need to **differentiate **f(x,y) = sin(x+y) with respect to s and t using the chain rule.

Let's start with fs(x(s,t),y(s,t)):

First, we substitute x(s,t) and y(s,t) into f(x,y):

f(x(s,t),y(s,t)) = sin(x+y) = sin(x(s,t) + y(s,t)).

Now, we differentiate f with respect to s, treating x(s,t) and y(s,t) as functions of s:

fs(x(s,t),y(s,t)) = cos(x(s,t) + y(s,t)) * (d/ds(x(s,t)) + d/ds(y(s,t))).

Using the chain rule, we can find d/ds(x(s,t)) and d/ds(y(s,t)):

d/ds(x(s,t)) = d/ds(s4t3) = 4s3t3,

d/ds(y(s,t)) = d/ds(4s−3t) = 4(-3s^-4)t = -12s^-4t.

Substituting these results back into fs(x(s,t),y(s,t)), we have:

fs(x(s,t),y(s,t)) = cos(x(s,t) + y(s,t)) * (4s3t3 - 12s^-4t).

Now, let's find ft(x(s,t),y(s,t)):

Again, we substitute x(s,t) and y(s,t) into f(x,y):

f(x(s,t),y(s,t)) = sin(x+y) = sin(x(s,t) + y(s,t)).

Now, we differentiate f with respect to t, treating x(s,t) and y(s,t) as functions of t:

ft(x(s,t),y(s,t)) = cos(x(s,t) + y(s,t)) * (d/dt(x(s,t)) + d/dt(y(s,t))).

Using the **chain rule**, we can find d/dt(x(s,t)) and d/dt(y(s,t)):

d/dt(x(s,t)) = d/dt(s4t3) = 12s^4t^2,

d/dt(y(s,t)) = d/dt(4s−3t) = -3(4s^-3) = -12s^-3.

Substituting these results back into ft(x(s,t),y(s,t)), we have:

ft(x(s,t),y(s,t)) = cos(x(s,t) + y(s,t)) * (12s^4t^2 - 12s^-3).

Therefore, fs(x(s,t),y(s,t)) = cos(x(s,t) + y(s,t)) * (4s3t3 - 12s^-4t) and ft(x(s,t),y(s,t)) = cos(x(s,t) + y(s,t)) * (12s^4t^2 - 12s^-3).

Solve the following DE using separable variable method. (i) (2 - 4) y dr - 2 (y2 - 3) dy = 0.

The **differential equation** given is,(2 - 4) y dr - 2 (y² - 3) dy = 0

To solve the differential equation using separable **variable method** we need to segregate the variables such that all the terms containing ‘r’ are on one side and all the terms containing ‘y’ are on the other side.

Now, we can write the above differential equation as,(2 - 4) y dr = 2 (y² - 3) dy

On solving the above equation, we get,y dr = (y² - 3) dy / 2

**Integrating **both sides, we get

∫(1 / y² - 3) dy / 2 = ∫1 drC = ∫(1 / y² - 3) dy / 2 -----(i)

Now, we need to solve the equation (i)

Let us consider the equation (i),C = ∫(1 / y² - 3) dy / 2

Now, let us take the variable, z = y² - 3

Therefore, dz / dy = 2y

Also, dy = dz / 2y

On the value of dy in equation (i), we get,C

= ∫dz / (2y * (y² - 3))C = (1 / 2)

∫(1 / z) dz = (1 / 2) ln |z| + K1C

= (1 / 2) ln |y² - 3| + K1

On solving for y, we get,ln |y² - 3| = 2C - K1

Taking the **exponential function **on both sides,e^ln |y² - 3| = e^(2C - K1)

We know that, e^ln a = a

Therefore,|y² - 3| = e^(2C - K1)y² - 3 = ± e^(2C - K1)

We can write the above equation as, y² - 3 = ke^(2C)

We know that, k = ± e^(-K1)

Therefore, y² - 3 = ± e^(2C - K1)

On solving for y, we get,y = ±sqrt(3 + e^(2C - K1))

In **probability** theory, the expected value of a random variable represents the **average** value that we would expect to obtain from repeated measurements. To calculate the expected value of X in this case, we need to integrate the density function f(x) over the range of X and multiply by X.

Given the density function f(x) = (6/√3) * φ(1+x²), where φ denotes the standard** normal distribution **function, we want to find E(X), the expected value of X. Since the density function is defined only for 0 < x < 1, we will integrate over this range.

Using the definition of expected value, E(X) = ∫(x * f(x)) dx, we can substitute the density function and limits to obtain:

E(X) = ∫[0,1] (x * (6/√3) * φ(1+x²)) dx.

To evaluate this **integral**, we would need a specific expression for the standard normal distribution function φ(x). Without that information, we cannot calculate the expected value precisely.

1. f(x) = √(25 - x)Sketching the graph of f(x) = √(25 - x) on the **Cartesian **plane:First, we need to plot the vertex. We know that the vertex is **located **at (25, 0) because f(x) is equal to zero when x is 25.

For example, we can find f(24) by plugging in 24 for x: f(24) = √(25 - 24) = 1. We can also find f(20) by plugging in 20 for [tex]x: f(20) = √(25 - 20) = √5 ≈ 2.236.[/tex]

By plotting these points and drawing a smooth curve, we get the following graph:2. f(x) = (x - 1)/(x + 1)

To sketch the graph of f(x) = (x - 1)/(x + 1), we can start by looking at the **behavior **of the function as x approaches positive or negative infinity. When x is very large, the terms x - 1 and x + 1 will be approximately equal, so f(x) will be approximately equal to (x - 1)/(x + 1) ≈ 1.

When x is very small and **negative**, the terms x - 1 and x + 1 will be approximately equal in magnitude but opposite in sign, so f(x) will be approximately equal to (x - 1)/(x + 1) ≈ -1.

To find the x-intercept, we set

f(x) = 0 and solve for

x: 0 = (x - 1)/(x + 1) x - 1

= 0

x = 1. So the graph of f(x) will cross the x-axis at

x = 1.

To find the y-**intercept**, we set

x = 0 and simplify:

f(0) = (0 - 1)/(0 + 1) = -1.

So the graph of f(x) will **cross **the y-axis at y = -1.

The total **area under the curve** of f(x) = 2x² from x = 0 to x = 5 is 250 **units squared**. The length of the curve y = 7(6 + x)² from x = 189 to x = 875 is approximately 3,944 units.

1. In the first problem, to find the area under the curve, we can integrate the function f(x) = 2x² with respect to x over the given **interval** [0, 5]. Using the power rule of integration, we integrate 2x² term by term, which results in (2/3)x³. Evaluating the **antiderivative** at x = 5 and subtracting the value at x = 0, we get (2/3)(5³) - (2/3)(0³) = 250 units squared.

2. In the second problem, we need to find the length of the curve y = 7(6 + x)² between x = 189 and x = 875. To calculate the length of a curve, we use the **arc length** formula. In this case, the formula becomes L = ∫[189, 875] √(1 + (dy/dx)²) dx. Differentiating y = 7(6 + x)² with respect to x, we obtain dy/dx = 14(6 + x). Plugging this into the arc length formula and **integrating** from x = 189 to x = 875, we get the length L ≈ 3,944 units.

According to the information, the **probability** that 95 students arrive in an **hour** is approximately 0.0439.

To calculate the **probability**, we need to determine the distribution that describes the arrival rate of students. Given that an average of 50 students arrive every 30 minutes, we can assume that the arrival rate follows a Poisson distribution.

In a Poisson distribution, the mean (μ) is equal to the arrival rate. In this case, μ = 50 students per 30 minutes.

To calculate the **probability** of a specific number of arrivals in a given time period, we can use the formula for the Poisson probability mass function:

Find zw and z/w, leave your answers in polar form.

z=6(cos 170° + i sin 170°) w=10(cos 200° + i sin 200°)

What is the product?

__ [ cos __ ° + sin __°]

(Simplify your answers. Type any angle measures in degrees. Use angle measures great)

What is the quotient?

__ [ cos __ ° + sin __°]

To find the product zw, we multiply the magnitudes and add the angles in polar form:

zw = 6(cos 170° + i sin 170°) * 10(cos 200° + i sin 200°)

zw = 60(cos 170° + i sin 170°)(cos 200° + i sin 200°)

zw = 60(cos 370° + i sin 370°)

zw = 60(cos 10° + i sin 10°)

The product is 60(cos 10° + i sin 10°).

To find the quotient z/w, we divide the magnitudes and subtract the angles in polar form:

z/w = 6(cos 170° + i sin 170°) / 10(cos 200° + i sin 200°)

z/w = (3/5)(cos 170° + i sin 170°)(cos(-200°) + i sin(-200°))

z/w = (3/5)(cos(-30°) + i sin(-30°))

z/w = (3/5)(cos 330° + i sin 330°)

The quotient is (3/5)(cos 330° + i sin 330°).

zw = 6(cos 170° + i sin 170°) * 10(cos 200° + i sin 200°)

zw = 60(cos 170° + i sin 170°)(cos 200° + i sin 200°)

zw = 60(cos 370° + i sin 370°)

zw = 60(cos 10° + i sin 10°)

The product is 60(cos 10° + i sin 10°).

To find the quotient z/w, we divide the magnitudes and subtract the angles in polar form:

z/w = 6(cos 170° + i sin 170°) / 10(cos 200° + i sin 200°)

z/w = (3/5)(cos 170° + i sin 170°)(cos(-200°) + i sin(-200°))

z/w = (3/5)(cos(-30°) + i sin(-30°))

z/w = (3/5)(cos 330° + i sin 330°)

The quotient is (3/5)(cos 330° + i sin 330°).

Find the Probability of ten random Z values for less than Zo.

To find the **probability** of ten random Z values being less than a given Z₀, we can use the cumulative distribution function (CDF) of the standard **normal distribution. **

The Z values represent **standardized values** from a standard normal distribution, with a mean of 0 and a **standard deviation** of 1. The CDF of the standard normal distribution gives us the probability of observing a Z value less than or equal to a specific value. By calculating the CDF for the given Z₀, we can find the probability of observing Z values less than Z₀.

Using statistical software or tables, we can input the value of Z₀ and calculate the corresponding **probability**. For example, if we find that the probability is 0.25, it means that there is a 25% chance of randomly selecting ten Z values that are all less than Z₀.

It's important to note that the probability of observing ten random Z values less than Z₀ will depend on the **specific value** of Z₀ chosen. Different values of Z₀ will yield different probabilities.

Present value = $11,000, and the interest rate is 7.8% compounded monthly for 6 years.

9. Find the present value of the annuity that will pay $2000 every 6 months for 9 years from an account paying interest at a rate of 4% compounded semiannually. (Round your final answer to two decimal places.)

The answer are:

8.**The periodic payment** is approximately $861.88.

9.**The present value of the annuity** is approximately $1012.8.

**What is the formula for the present value of an annuity?**

**The formula for the present value (PV) **of an annuity is given by**:**

[tex]PV =\frac{ P(1 - (1 + r)^{-n}}{r}[/tex]

Where:

PV = Present Value

P = **Periodic payment **

r = **Interest rate per period**

n = Number of periods

8.In this case, we are given:

Present Value (PV) = $11,000

Interest Rate (r) = 7.8% = 0.078 (converted to decimal)

Number of Periods (n) = 6 years * 12 months/year = 72 months

Let's substitute the given values into the formula and solve for the periodic payment (P):

[tex]$11,000 =\frac{ P(1 - (1 + 0.078)^{-72})}{0.078}[/tex]

Now we can solve this equation to find the periodic payment:

[tex]{$11,000}*{0.078} = P(1 - (1 + 0.078)^{-72})[/tex]

[tex]858 = P(1 - 0.004481)\\P = \frac{858}{1 - 0.004481}\\P = \frac{858}{ 0.9955}\\ P= 861.88[/tex]

Therefore, the periodic payment is approximately $861.88.

9.To find the present value of an annuity, we can use the present value formula again.

In this case, we are given:

Periodic Payment (P) = $2000

Interest Rate (r) = 4% = 0.04 (converted to decimal)

Number of Periods (n) = 9 years * 2 semesters/year = 18 semesters

Let's substitute the given values into the formula and solve for the present value (PV):

[tex]PV =2000 *\frac{1 - (1 + 0.04)^{-18}}{0.04}[/tex]

Now we can solve this equation to find the present value (PV):

[tex]PV = $2000 *(1 - 1.04^{-18})\\ PV = $2000 * (1 - 0.4936)\\PV=$2000 * 0.5064\\ PV =$1012.8[/tex]

Therefore, the present value of the annuity is approximately $1012.8.

Now integrate to find arc length = ².³∫₋₄√1+y'² dx =....

The simplified **expression** for √(1 + y'²) is obtained, and then integrated to find the arc length of the **curve**.

To find the arc length of the curve y = 4ln(16 - x²), we need to **calculate** √(1 + y'²), where y' represents the derivative of y with respect to x. **Differentiating** y with respect to x gives y' = -8x / (16 - x²).

Simplifying √(1 + y'²), we **substitute** y' into the expression and obtain √(1 + (-8x / (16 - x²))²). This simplifies to √(1 + 64x² / (16 - x²)²).

To find the arc length, we integrate √(1 + 64x² / (16 - x²)²) with respect to x over the interval [-4, 2.3]. This gives the arc length as the definite **integral** from -4 to 2.3 of the **simplified** expression.

(b) [10 points] How many ways can three gaming groups of 4 can be formed if there is no distinc- tion between each gaming group?

There are 27,720 ways to form gaming groups with specific distinctions: a competitive group, a casual group, and a group playing with an **expansion**, and without any distinction between the groups, there are 9,240 ways to form three gaming groups of 4 people each.

(a) The number of ways to form gaming groups with specific distinctions is:

(12 choose 4) * (8 choose 4) * (4 choose 4) = 27,720 ways.

To determine this, we use the concept of **combinations**. In the first step, we choose 4 people out of the 12 to form the competitive group. Then, from the remaining 8 people, we choose another 4 to form the casual group.

Finally, from the remaining 4 people, we choose all 4 to form the group playing with an expansion. By multiplying these three combinations together, we obtain the total number of ways to form the gaming groups with specific distinctions.

(b) If there is no **distinction** between the gaming groups, we need to consider that the order of the groups doesn't matter. In this case, the number of ways to form three gaming groups of 4 people each is:

(12 choose 4) * (8 choose 4) * (4 choose 4) / 3! = 9,240 ways.

We divide by 3! (the factorial of 3) to account for the fact that the order of the groups doesn't affect the **outcome**. This ensures that each combination of groups is counted only once.

Based on the information provided, Class B had a higher mean score of 8 compared to Class A's mean score of 7.5.

This suggests that, on average, the students in Class B performed better than those in Class A. When considering the** consistency** of scores, we look at the standard deviation.

Class B had a smaller standard deviation of 0.8, indicating that the scores were more tightly clustered around the mean.

On the other hand, Class A had a larger standard deviation of 1.1, suggesting more variability or inconsistency in the scores.

Therefore, Class B not only** scored **better on average but also had more consistent scores compared to Class A.

Vectors u = (1.-1.1.1) and v = (1, 1,-1, 1) are orthogonal. Determine values of the scalars a, b that minimise the length of the difference vector d = z-w, where z = (-2.3, -2,-1) and w=a.u+b.v. You m

it is not possible to find values of a and b that **minimize **the length of d = z - w while keeping d **orthogonal **to both u and v.

To determine the values of the **scalars **a and b that minimize the length of the difference **vector **d = z - w, where z = (-2, 3, -2), and w = a*u + b*v, we need to find the values of a and b such that the vector d is orthogonal to both u and v.

Let's first calculate the vectors u and v:

u = (1, -1, 1, 1)

v = (1, 1, -1, 1)

Next, we'll find the dot **product **of d with both u and v and set them equal to zero to ensure orthogonality:

d · u = 0

d · v = 0

Substituting the values of d, u, and v:

(-2, 3, -2) · (1, -1, 1, 1) = 0

(-2, 3, -2) · (1, 1, -1, 1) = 0

Expanding the **dot products**:

-2*1 + 3*(-1) + (-2)*1 + (-2)*1 = 0

-2*1 + 3*1 + (-2)*(-1) + (-2)*1 = 0

Simplifying the equations:

-2 - 3 - 2 - 2 = 0

-2 + 3 + 2 - 2 = 0

-9 = 0

-1 = 0

From these equations, we see that there is no solution that satisfies both conditions simultaneously. Therefore, there are no values of the scalars a and b that can minimize the length of the **difference **vector d = z - w while ensuring orthogonality to both u and v.

In other words, it is not possible to find values of a and b that minimize the length of d = z - w while keeping d orthogonal to both u and v.

During a particular week six months ago, suppose that the price of a 1 pound slab of Scottish Coho salmon at your local grocery store was $20; currently the price is $25/lb. The manager informs you that 100 pounds were sold during a particular week six months ago when the price was $20/lb. while 80 pounds were sold this week.Calculate the price elasticity of demand (point formula, not midpoint/arc formulaconsult the textbook). Based solely on your calculation, is the demand relatively elastic or relatively inelastic?If the grocery store is a price setter, should it increase or decrease the price of salmon to increase its revenue? Only consider this one goodkeep it simple. Answer in a few sentences
The heat lost by a thermal system is given as hl.T, where h is the heat transfer coefficient, 7 is the temperature difference from the ambient, and L is a characteristic dimension h=3 (3) It is also given that the temperature T must not exceed 7.51/4. Assuming that the mentioned maximum temperature is available (hence T = 7.5L/4), calculate the dimension L. that minimizes the heat loss. PART II: FUNCTION OF TWO VARIABLES The cost Cefa storage chamber is given in terms of three dimensions as C= 8x +4 +52 xy With the volume given as xyz = 40. Recast this problem as an unconstrained problem with two 40 from the decision variables, and determine the dimensions that minimize the cost. (Hint: 2 given volume equation. So you can substitute this into C and make it an objective function with only two decision variables; x and y).. coded that they used. Part 1 (40p): Each part is 10 points Students should solve the question stated in Part 1 by using Matlab (or obtaining some parts of the answers from Matlab). Solving by using Matlab includes the following steps (computations should be done by Matlab, therefore, the related codes should be write to perform the computations automatically) a) Plot the objective function in terms of the decision variable, to observe how the function changes according to this variable. The plot should have all the necessary labels. b) Find the critical points of the function c) Determine if the critical points are local minima, maxima or saddle point d) Use a line search technique (univariate search method, or single variable optimization algorithm) lecture notes and mentioned in explained in Nonlinear Programming Algorithms
