Answer:

9.5 feet

Step-by-step explanation:

We solve this question using Sine rule

XY/sin X = YZ/Sin Z

From the question:

∠Z=90°

∠X=57°

XY = 8 feet.

8/sin 57 = YZ/sin 90

Cross Multiply

sin 57 × YZ = 8 × sin 90

YZ = 8 × sin 90/sin 57

YZ = 9.53891 feet

Approximately = 9.5 feet

Therefore, the length of YZ is 9.5 feet

\({ \rm{area \: of \: box = 10 \times 10}} \\ { \underline{ \rm{ \: \: = 100 \: in {}^{2} \: \: }}}\)

and:

\({ \rm{area \: of \: circle = \pi {r}^{2} }} \\ { \rm{ = 3.14 \times {(5)}^{2} }} \\ = { \underline{ \rm{ \: \: 78.5 \: in {}^{2} \: \: }}}\)

Difference:

\({ \rm{ = 100 - 78.5}} \\ \\ = { \boxed{ \rm{ \: 21.5 \: {in}^{2} \: }}}\)

The difference between the area of the box and the pizza is 21.5 in².

The area of a two-dimensional region, form, or planar lamina in the plane is the quantity that represents its extent. On the two-dimensional surface of a three-dimensional object, the surface area is its counterpart.

\(\text{Area of Square} = (\rm Side)^2\)

\(\text{Area of Circle} = \pi(\rm r)^2\)

The difference between the area of the box and the pizza can be found by finding the difference between the area of the box and the area of the circle.

Now, the area of the square box with a side of 10 inches, can be written as,

\(\text{Area of the Box} = \text{Area of the Square}\)

                          \(= a^2\\\\=(10)^2\\\\=100\rm\ in^2\)

Thus, the area of the square box is 100 in².

The area of the pizza with a radius of 5 inches can be written as,

\(\text{Area of the Pizza} = \text{Area of the circle}\)

                            \(= \pi r^2\\\\=\pi (5)^2\\\\=78.5\rm\ in^2\)

Thus, the area of the pizza is 78.5 in².

Further, the difference between the area of the box and the pizza can be written as,

The difference between the area = Area of the box - Area of Pizza

                                                        = 100 in² - 78.5 in²

                                                         = 21.5 in²

Hence, the difference between the area of the box and the pizza is 21.5 in².

The first iterated integral integrates over y first, giving the limits of integration for x as y/3 to 243^(1/3). The second iterated integral integrate over x first, giving the limits of integration for y as 0 to 3x^(1/3).

a) To express the area element dA as a double integral using vertical cross-sections, we can integrate with respect to x and y separately. Since the region R is bounded by the lines y = Vx, y = 0, and x = 243, the limits of integration are:

- For y, the lower limit is 0 and the upper limit is Vx.

- For x, the lower limit is 0 and the upper limit is 243.

Therefore, the iterated integral for dA using vertical cross-sections is:

∫[from 0 to 243]∫[from 0 to Vx] dy dx

b) To express the area element dA as a double integral using horizontal cross-sections, we can also integrate with respect to x and y separately. However, the limits of integration are different:

- For x, the lower limit is 0 and the upper limit is y/V.

- For y, the lower limit is 0 and the upper limit is 243.

Therefore, the iterated integral for dA using horizontal cross-sections is:

Answer:

The answer is 120 feet.

Step-by-step explanation:

The area of the field (A) is:

A = w · l       (w - width, l - length)

It is known:

A = 12,000 ft²

l = w - 20

So, let's replace this in the formula for the area of the field:

12,000 = w · (w - 20)

12,000 = w² - 20

⇒ w² - 20w - 12,000 = 0

This is quadratic equation. Based on the quadratic formula:

ax² + bx + c = 0      ⇒  

In the equation w² - 20w - 12,000 = 0, a = 1, b = -20, c = -12000

Thus:

So, width w can be either

or

Since, the width cannot be a negative number, the width of the field is 120 feet.

The length of the field is 120 feet.

Option C is the correct answer.

A rectangle is a 2-D shape with length and width.

The length and width are different.

If the length and width are not different then it is a square.

The area of a rectangle is given as:

Area = Length x width

We have,

Let's start by using the given information to set up two equations:

Let x be the length of the field in feet.

Then, the width of the field is x - 20 feet.

The area of the field is given as 12,000 square feet:

x (x - 20) = 12,000

Expanding the left side of the equation, we get:

x² - 20x = 12,000

Bringing all the terms to one side, we get:

x² - 20x - 12,000 = 0

Now, we can solve this quadratic equation using factoring,

Completing the square, or the quadratic formula.

Here, we will use factoring:

x² - 20x - 12,000 = 0

(x - 120) (x + 100) = 0

The solutions are x = 120 and x = -100, but a negative length doesn't make sense, so we reject that solution.

Therefore,

The length of the field is 120 feet.

To check, we can substitute x = 120 into the equation for the width:

Width = x - 20 = 100 feet

Area = Length x Width

= 120 ft x 100 ft

= 12,000 sq ft

Thus,

The length of the field is 120 feet.

Answer:

the answer is the question with $580 in it please correct me if im wrong

Step-by-step explanation:

Jean can expect to earn about $580 on her investment of $4,250 if she invests in FLMD.

The expected return on SOLR is calculated by multiplying the probability of each outcome by the amount of the gain or loss, and then adding these results:

50% chance of $1,000 gain: 0.5 x $1,000 = $500

35% chance of $200 gain: 0.35 x $200 = $70

15% chance of $600 loss: 0.15 x -$600 = -$90

Therefore, the expected return on SOLR is $500 + $70 - $90 = $480.

The expected return on FLMD is calculated in the same way:

80% chance of $750 gain: 0.8 x $750 = $600

20% chance of $100 loss: 0.2 x -$100 = -$20

Therefore, the expected return on FLMD is $600 - $20 = $580.

Since the expected return on FLMD is higher than the expected return on SOLR, FLMD is the better investment.

The expected return on FLMD is $580, which means that Jean can expect to earn about $580 on her investment of $4,250 if she invests in FLMD.

\( - 16 + 2\)

Think of -16 as a debt . Lets say you are owing someone $16

Think of +2 as the amount of money with you that hasn't been spent.

Now let's put the story together.

You are owing someone $16 and you pay the person $2(the only money you have on you ).

Definitely, you will still be owing the person and amount of $14

\(16 - 2 = 14\)

And remember - means owing

+ means you're paying or you're having

So that means you're owing $14

So the answer = -14

In order to completely delta hedge 480 shares of ABC company with an option delta of 0.6, you would need 3 call options.

To completely delta hedge your holdings of 480 shares of ABC company, you would need to calculate the number of call options required based on the delta of the option. The delta represents the change in the option price relative to the change in the underlying stock price. In this case, since the delta is given as 0.6, it means that for every $1 increase in the stock price, the option price will increase by $0.6.

To calculate the number of call options needed for delta hedging, you can use the following formula:

Number of call options = (Delta * Number of shares) / 100

Plugging in the given values, we have:

Number of call options = (0.6 * 480) / 100

Number of call options = 2.88

Since you cannot have a fractional number of options, you would need to round up to the nearest whole number. Therefore, you would need 3 call options to hedge your 480 shares of ABC company.

In summary, to completely delta hedge 480 shares of ABC company with an option delta of 0.6, you would need to acquire 3 call options.

Step-by-step explanation: Multiply -36 and 163/9 to get -652. Add 652 to both sides then add 130 and 652 to get 782. Divide both sides by -12 then reduce the fraction 782/-12 to lowest terms by extracting and canceling out 2. The system is now solved.

To find the value of x, we need to use the fact that the sum of the angles in a triangle is 180 degrees.

In triangle DEF, we know that m2 DEF = (5x – 10). We also know that m1 DEF = 90 degrees (since it's a right angle).

Using the fact that the sum of the angles in a triangle is 180 degrees, we can write an equation:

m1 DEF + m2 DEF + m3 DEF = 180

Substituting in our known values, we get:

90 + (5x – 10) + m3 DEF = 180

Simplifying, we get:

5x + m3 DEF = 100

We don't know the value of m3 DEF, but we do know that it's an angle in circle M. We also know that angles in the same segment of a circle are equal.

Since angle DEF is in the same segment as m3 DEF, we know that m3 DEF = m1 DEF = 90 degrees.

Substituting this into our equation, we get:

5x + 90 = 100

Solving for x, we get:

5x = 10

x = 2

Therefore, the value of x is 2.

The value of x is 20

We know that an angle inscribed in a semicircle, is always a right angle.

This means that in the attched figure, the angle DEF is a right angle.

So, m∠DEF = 90°

But m∠DEF = (5x - 10)°

From (1) and (2) we get,

(5x - 10)° = 90°

5x - 10 = 90

We solve this equation for x.

5x -10 + 10 = 90 + 10

5x = 100

x = 100/5

x = 20

The given mathematical expression is evaluated for the input values (2, 4). The result of the expression is calculated using various operations such as addition, multiplication, square root, natural logarithm, minimum, maximum, and function composition.

The expression f(x1, x2) involves several mathematical operations. Let's evaluate each part of the expression step by step:

1. The first term is 421 + 222, which equals 643.

2. The second term is 3x² + 213. Plugging in x1 = 2 and x2 = 4, we get 3(2)² + 213 = 3(4) + 213 = 12 + 213 = 225.

3. The third term is 5x11². Substituting x1 = 2 and x2 = 4, we have 5(2)(11)² = 5(2)(121) = 1210.

4. The fourth term is (√₁+√₂)². Replacing x1 = 2 and x2 = 4, we obtain (√2 + √4)² = (1 + 2)² = 3² = 9.

5. The fifth term is 10ln(₁). Plugging in x1 = 2, we have 10ln(2) = 10 * 0.69314718 ≈ 6.9314718.

6. The sixth term is (x₁+x₂)(x² + x3). Substituting x1 = 2 and x2 = 4, we get (2 + 4)(2² + 4³) = 6(4 + 64) = 6(68) = 408.

7. The seventh term is min(3r1, 10√2). As we don't have the value of r1, we cannot determine the minimum between 3r1 and 10√2.

8. The eighth term is max{5x1,2r2}. Since we don't know the value of r2, we cannot find the maximum between 5x1 and 2r2.

9. Finally, we have MP1(x1, x2), MP2(X1, X2), and TRS(x1, x2), which are not defined or given.

Considering the given expression, the evaluated terms for the input values (2, 4) are as follows:

- 421 + 222 = 643

- 3x² + 213 = 225

- 5x11² = 1210

- (√₁+√₂)² = 9

- 10ln(₁) ≈ 6.9314718

- (x₁+x₂)(x² + x3) = 408

The terms involving min() and max() cannot be calculated without knowing the values of r1 and r2, respectively. Additionally, MP1(x1, x2), MP2(X1, X2), and TRS(x1, x2) are not defined.

A function that models the brightness of the star as a function of time is

M = -.35 sin (t • pi/2.7) + 4.4

First, let's create a table to find when the star will be at its maximum, minimum and its average, and what direction the magnitude will be moving at that time.

t = 0, M = 4.4 +

t = 1.35, M = 4.75 -

t = 2.7, M = 4.4 -

t = 4.05, M = 4.05 +

t = 5.4, M = 4.4 +

t = 6.75, M = 4.75 -

The t=0, entry is given by the parenthetical.  The period is given as 5.4 days (the time between the start of each cycle), so the star will reach its maximum at 1.35 days, return to average at 2.7 days, reach its minimum at 4.05 days, return to average at the period interval, 5.4 days, and then reach maximum again in 6.75 days.  The difference between 6.75 and 1.35 days (the time between maximums) is 5.4 days, as required.

There are many functions that might be chosen, I would choose a sine or cosine function.  The choice between sine and cosine is usually best done on whether you want the initial value of the function to be 0 (sine) or 1 (cosine).  Here, we start at the average value, so we are better off starting with sine.  The amplitude of the sine function needs to be the change from the average value (positive or negative) or .35, since the sine of 0, pi, 2pi, 3pi ... is 0, we need to move the center line of the sine function up by 4.4, the average value of the magnitude.  Finally, we need multiply the time value in order to adjust the time into the appropriate radian measure for the 5.4 day period.  So we want

0 days -> 0 radians

1.35 days -> pi/2 radians

2.7 days -> pi radians

4.05 days -> 3pi/2 radians

5.4 days -> 2pi radians

So we need to divide each time value by half the period (2.7) and multiply it by pi or pi/2.7.

Thus, the best sinusoidal equation is

M = .35 sin (t • pi/2.7) + 4.4

This assumes that a magnitude of 4.75 is brighter than 4.4, which would be brighter than 4.05.  If magnitude works the other way, then all you need to do is change the sign or the equation, i.e.

M = -.35 sin (t • pi/2.7) + 4.4

The finite difference approximation for a Neumann boundary condition, \(\left(\frac{df}{dx}\right)\), at node \(n\) (right boundary) to \(O(h^2)\) is given by

\(\left(\frac{df}{dx}\right)_n \approx \frac{f_{n-2} - 4f_{n-1} + 3f_n}{2h}\),

where \(f_{n-2}\), \(f_{n-1}\), and \(f_n\) represent the function values at nodes \(n-2\), \(n-1\), and \(n\) respectively, and \(h\) represents the spacing between the nodes.

To derive this approximation, we start with the Taylor series expansion of \(f_{n-1}\) and \(f_n\) around \(x_n\):

\(f_{n-1} = f_n - hf'_n + \frac{h^2}{2}f''_n - \frac{h^3}{6}f'''_n + \mathcal{O}(h^4)\),

\(f_{n-2} = f_n - 2hf'_n + 2h^2f''_n - \frac{4h^3}{3}f'''_n + \mathcal{O}(h^4)\).

By subtracting \(4f_{n-1}\) and adding \(3f_n\) from the second equation, we eliminate the first-order derivative term and retain the second-order derivative term. Dividing the result by \(2h\) gives us the desired finite difference approximation to \(O(h^2)\).

In conclusion, the finite difference approximation for a Neumann boundary condition, \(\left(\frac{df}{dx}\right)\), at node \(n\) (right boundary) to \(O(h^2)\) is \(\left(\frac{df}{dx}\right)_n \approx \frac{f_{n-2} - 4f_{n-1} + 3f_n}{2h}\). This approximation is obtained by manipulating the Taylor series expansion of \(f_{n-1}\) and \(f_n\) to eliminate the first-order derivative term and retain the second-order derivative term, resulting in a second-order accurate approximation.

The cost of walking this guest is $190.

The cost of walking the guest can be calculated by adding up the expenses incurred by the hotel.

The guest was walked to another hotel that charged a room rate of $150. Therefore, the hotel incurred a cost of $150 for the room.

In addition to the room cost, the hotel also paid for the guest's Uber ride to the new hotel, which was $15.

Furthermore, the overbooked hotel gave the guest a gift card worth $25. Although the gift card does not directly represent an expense, it can be considered as an opportunity cost for the hotel, as they could have used that money to cover other costs.
