Using the inscribed angle theorems, the measure of the indicated angles are:

1. m∠BOA = 26°

2. m∠BDA = 13°

3. m∠BCA = 13°

Based on the inscribed angle theorem, the following relationships are established:

Given:

Intercepted arc BA = 26°

1. ∠BOA is central angle

Thus:

m∠BOA = 26° (inscribed angle theorems)

2. ∠BDA is inscribed angle.

m∠BDA = 1/2(30) = 13° (inscribed angle theorems)

3. m∠BCA = m∠BDA = 13° (inscribed angle theorems)

The line integral in both cases is  52/3

Given,

a) The line integral; L = ∫c xy dx + x² y³ dy

 Where C is counterclockwise around the triangle with vertices (0, 0),

(1, 0)  and (1, 4)

Our first line integral is

L₁ = ₁∫₍₀, ₀₎ ⁽¹ ⁰⁾ xy dx + x² y³ dy

The equation of this line is y = 0,  x varies from 0 to 1.

L₁ = 0

Our second line integral is

L₂ = ₁∫₍₁, ₀₎ ⁽¹ ⁴⁾ xy dx + x² y³ dy

The equation of this line is x = 0  and y varies from 1 to 4.

L₂ = 64/3

The third line integral is

L₃ = ∫₁⁰ xy dx + x² y³ dy

The equation of this line is y = 4x  and x varies from 0 to 1.

L₃ = -4

The value of the line integral is

L = L₁ + L₂ + L₃ = 0 + 64/3 + (-4) = 52/3

b) The second part requires the use of Green's Theorem to evaluate:

This is given by:

∫c Pdx + Qdy = ∫ ∫ R Qy - Px dA

∫c xy dx + x² y³ dy = ∫ ∫R 3x² y² - ydA

We choose our region of integration parallel to the y-axis.

∫c xy dx + x² y³ dy

= ∫¹₀ ∫⁴ˣ₀ 3x² y² - y dy dx

= ∫¹₀ x² y³ - 1/4 |y²|²ˣ₀ dx

=  ∫¹₀ 64x⁵ - 4x² dx = 52/3

longest side is called hypotenious (h)

and u can assume any of the remaining side as p and b as your choice

eg=

1) h=13

p=12

b=?

using pythagrous theroem

h²=p²+b²

13²=12²+b²

For n colors in the bag, you would need to pull out (n+1) marbles to guarantee two marbles of the same color.

The number of marbles you would have to pull out to get two marbles of the same colour, when there are three colors in the bag, let's consider each case individually:
Case 1: Three colors in the bag
To guarantee two marbles of the same color, you would need to pull out four marbles. This is because the worst-case scenario would be pulling out one marble of each color first, and then the fourth marble would be guaranteed to match one of the previously pulled marbles.
General formula: For n colors in the bag, you would need to pull out (n+1) marbles to guarantee two marbles of the same color.
Case 2: Four colors in the bag
To guarantee two marbles of the same color, you would need to pull out five marbles. Following the same reasoning as before, pulling out four marbles could result in one of each color, and the fifth marble would guarantee a matching pair.
General formula: For n colors in the bag, you would need to pull out (n+1) marbles to guarantee two marbles of the same color.
Remember, this analysis assumes that all marbles are equally likely to be chosen and does not involve probability calculations.

The functions I(x) and E(x) of the theatre's income and expenses are illustrations of linear functions.

The theatre charges $4.50 per student.

Assume the number of students is x, the equation of the theatre's income would be:

I(x) = 4.5x

The theatre expense per student is $1.25, and the operating cost on the staff is $130

The equation of the theatre's expenses would be:

E(x) = 1.25x + 130

Using the formulas I(x) = 4.5x and E(x) = 1.25x + 130, the complete table is:

Students, x  0       10        20     30      40      50      60    70

Income, I      0      45        90     135     180    225    270   315

Expenses, E 130  142.5   155    167.5   180   192.5   205  217.5

See attachment

The functions I(x) and E(x) are linear functions.

So, the pattern with which the functions increase is a linear pattern.

This means that:

I(x) = E(x)

So, we have:

4.5x = 1.25x + 130

Subtract 1.25 from both sides

3.25x = 130

Divide both sides by 3.25

x = 40

Hence, the number of students is 40

This is the difference between the theatre expenses and their income.

So, we have:

P(x) = E(x) - I(x)

This gives

P(x) = 1.25x + 130 - 4.5x

Simplify

P(x) = 130 - 3.25x

We have:

E(x) < 255

This gives

1.25x + 130 < 255

Subtract 130 from both sides and divide by 1.25

x < 100 students

Also, we have:

I(x) > 675

This gives

4.5x > 657

Solve for x

x > 146 students

Hence, the number of students for the inequalities are less than 100 and greater than 146

Mr.johns invested money in each business is first business = $26909

and second business = $27909.

Given:

Last year he gained 10% on the first investment and 12% on the second if he invested $1000 more in the first business and gained a total of $6040.

Let x be the money invested in first business

From given statements:

10x/100 + (x + 1000)12/100 = 6040

multiply by 100 on both sides

10x + 12(x + 1000) = 6040*100

10x + 12x + 12000 = 604000

22x = 604000 - 12000

22x = 59200

x = 26909 invested in first business.

second business investment = 26909 + 1000 ⇒ 27909.

Therefore Mr.johns invested money in each business is first business = $26909 and second business = $27909.

The amount of money left with me with the help of calculation is 18 quarters.

In order to convert percentages to numbers, take the base as 100 and calculate with respect to it.

The initial amount of quarters I had is 30 quarters.

Now since 20% more is added, hence 120% of 30 = 36

Now, I spend 50% of the total number of quarters.

Hence quarters spent- 50% of 36= 18

So, the quarters left - 36-18= 18 quarters

According to Descartes' Rule of Signs, there is 1 positive real zero and 2 or 0 negative real zeroes of the polynomial.

Descarte's Rule of Signs determines the number of real zeros in polynomial functions.

This indicates that -

The number of positive real zeros in the polynomial function f(x) is less than or equal to an even number depending on the sign change of the coefficients.

The number of negative real zeros in f(x) is an even number equal to or less than the number of sign changes of the coefficients of f(-x) terms.

Here, the polynomial function is given as -

\(P(x)=x^{3}-x^{2} -x-5\) ----- (1)

We have to find out the number of positive and negative real zeros that  the given polynomial can have.

The given polynomial already has its variables in the descending powers. So, we can easily determine the number of sign changes in the coefficients of P(x).

So, the coefficients of the variables in P(x) are -

1, -1, -1, -5

From above, we see that -

There is a sign change in the first and second variable coefficients

There is no sign change in the second and third variable coefficients

There is no sign change in the third and fourth variable coefficients

According to Descartes' Rule of Signs, there can be exactly three positive real zeros or less than three but an odd number of zeros.

So, we can determine that the number of positive real zeroes of the given polynomial can be 1.

To find out the negative real zeroes of the given polynomial, we have to find out P(-x) and determine the sign changes in the variable coefficients of P(-x).

From equation (1), we can write P(-x) as -

\(P(x)=x^{3}-x^{2} -x-5\\= > P(-x)=(-x)^{3}-(-x)^{2} -(-x)-5\\= > P(-x)=-x^{3}-x^{2} +x-5\)----- (2)

So, the coefficients of the variables in P(-x) are -

-1, -1, +1, -5

From above, we see that -

There is no sign change in the first and second variable coefficients

There is a sign change in the second and third variable coefficients

There is a sign change in the third and fourth variable coefficients

According to Descartes' Rule of Signs, since there are two sign changes of the coefficient variables, there can be two negative real zeros or less than two but an even number of zeros.

So, we can determine that the number of negative real zeroes of the given polynomial can be 2 or 0.

Thus, according to Descartes' Rule of Signs, there is 1 positive real zero and 2 or 0 negative real zeroes of the polynomial.

The average of the sample ranges for the weight of packages of Skittles is 0.11. So, the correct answer is (e) 0.11.

To find the average of the sample ranges for the weight of packages of Skittles, we first calculate the range for each sample. The range is the difference between the maximum and minimum values in each sample.

Sample 1: Range\(= 3.62 - 3.58 = 0.04\)

Sample 2: Range\(= 3.65 - 3.49 = 0.16\)

Sample 3: Range \(= 3.65 - 3.45 = 0.20\)

Sample 4: Range \(= 3.64 - 3.54 = 0.10\)

Sample 5: Range\(= 3.62 - 3.49 = 0.13\)

Next, we calculate the average of these sample ranges:

A\(verage = (0.04 + 0.16 + 0.20 + 0.10 + 0.13) / 5 = 0.11\)

Therefore, the average of the sample ranges for the weight of packages of Skittles is \(0.11\). So, the correct answer is (e) \(0.11.\)

The dimensions that yield the box with the largest volume are 5√2 inches by 5√2 inches by 5√2 inches.

To maximize the volume of the box, we need to determine the dimensions that will use up all 100 square inches of material while maximizing the volume of the box. Let the length, width, and height of the box be denoted by x, y, and z, respectively.

From the given information, we know that the surface area of the box is 2(xy + xz + yz) = 100, which simplifies to xy + xz + yz = 50.

The volume of the box is V = xyz, so we need to find the maximum value of V subject to the constraint xy + xz + yz = 50.

We can use Lagrange multipliers to solve this optimization problem. Let

f(x, y, z) = xyz

g(x, y, z) = xy + xz + yz - 50

The Lagrangian function is

L(x, y, z, λ) = f(x, y, z) - λg(x, y, z) = xyz - λ(xy + xz + yz - 50)

Taking partial derivatives with respect to x, y, z, and λ and setting them equal to zero, we get the following system of equations:

yz - λ(y + z) = 0

xz - λ(x + z) = 0

xy - λ(x + y) = 0

xy + xz + yz - 50 = 0

Solving this system of equations yields

x = y = z = 5√2

Therefore, the dimensions that yield the box with the largest volume are 5√2 inches by 5√2 inches by 5√2 inches.
