Step-by-step explanation:

100 shares   *  .20 / share  * 4 times / year = $80.00 annual  

The annual dividend received from owning 100 shares of stock of company A that pays 20 cents per quarter will be $80.

Dividend is a regular payment made by the company to its equity shareholders on pro-rata basis as a percentage of the profit earned by the company. The company pays its subscribers a dividend 20 cents per quarter. So annually, the company will pay four times the amount, i.e., 80 cents (20 x 4).

80 cents will be the dividend paid by the company per share per year. so for a hundred shares of stock, the company will pay the:

Annual Dividend = 0.20 x 4 x 100

Annual Dividend = 0.80 x 100

The client will be receiving 1.67 ml of medication in one minute and it will have 0.334 g of medication per minute.

Here 2g  of medication is diluted with 100 ml of normal saline. So concentration of 1ml of normal saline would be,

Concentration of 1 ml = 2/100 = 0.02 g/ml

It is delivered over a period of 1 hour. So, the amount delivered per minute will be,

Amount per minute = Volume/ time = 100/60 = 1.67 ml

Amount of medication in 1.67 ml = Volume × Amount per ml

                                                     = 1.67 × 0.02 = 0.334 g

Answer: The length of the hypotenuse of the right-angled triangle is 31.62 cm.

Step-by-step explanation:  Given , that the legs of the right-angled triangle are 18 cm and 26 cm

Lets assume that the two sides of the right-angled triangle :

AC = 18 cm , BC = 26 cm

According to Pythagoras Theorem - In a right- angled triangle , the square of the hypotenuse side is equal to the sum of squares of two sides .

Therefore, according to the diagram AB² = AC² + BC²

⇒ AB² =  (18)² + (26)²

The sum or difference of two fractions is not in Improper form.

Fraction is a part of a whole number. It is represented by two numbers separated by a line. The top number is called the numerator and the bottom number is called the denominator. The numerator represents the number of parts of the whole, and the denominator represents the total number of parts. For example, 1/2 is a fraction that represents one part of a whole that is divided into two equal parts. Fractions are used in many mathematical calculations such as addition, subtraction, multiplication and division.

When adding or subtracting fractions, it is important to first convert the fractions to improper form. Improper form is when the numerator (the top number of the fraction) is larger than the denominator (the bottom number of the fraction). For example, the improper form of 1/2 is 3/2.

To convert a fraction to its improper form, simply multiply the numerator and denominator by the same number. For example, let’s convert the fraction 1/2 to its improper form. To do this, we multiply the numerator (1) and denominator (2) by 2. This gives us 2/4, which is the same as 3/2 (the improper form).

Once all the fractions have been converted to improper form, they can be added or subtracted by simply adding or subtracting the numerators (top numbers) and keeping the denominator (bottom number) the same.

For example, let’s say we want to add 3/4 and 1/2. To do this, we convert both fractions to improper form: 3/4 becomes 6/4, and 1/2 becomes 3/2. Then, we add the numerators (6 + 3 = 9) and keep the denominator the same (4). This gives us the answer of 9/4.

the maximum dimensions of the box would be 60 cm x 60 cm x 60 cm in order to have the maximum allowable volume while still meeting the airline's luggage restrictions.

If the length and width of the box are equal, we can call the length and width x. Then, the height of the box would also be x in order to maximize the volume.

The sum of the length, width, and height of the box would be:

x + x + x = 3x

We know that the sum of the length, width, and height must be less than or equal to 180 cm. So:

3x ≤ 180

Simplifying, we get:

x ≤ 60

Dimensions, the sum of the length, width, and height is 360 cm.

Let's assume that the length, width, and height of the box are all equal to

x cm. Since the length and width are equal, we can write:

Length = Width = x

The volume of the box can be expressed as:

Volume = Length x Width x Height

Volume = x × x × (180 - 2x) (since the height is equal to 180 - length - width)

To find the dimensions of the box that would give us the maximum volume, we need to differentiate the volume function with respect to x and set it equal to zero:

[tex]dV/dx = 3x^2 - 360x = 0[/tex]

Solving this equation, we get:

x = 0 or x = 120

Since x cannot be zero, the only possible value for x is 120 cm. Therefore, the dimensions of the box should be:

Length = Width = Height = 120 cm

Linear pair angles are angles that together form a straight line.

Linear pair angles are supplementary.

The linear pair angles, ∠FLS and ∠FLG, indicates;

(4·x + 12)° + (3·x)° = 180°

7·x + 12 = 180

7·x = 180 - 12 = 168

x = 168/7 = 24

x = 24

Therefore; m∠FLS = (4 × 24 + 12)° = 108°

∠SLT ≅ ∠FLG, vertical angles theorem, therefore;

m∠SLT = m∠FLG = (3·x)°

Step-by-step explanation:

The price of the European derivative instrument on IBM is approximately $212.80.

Based on the graph, we can see that the payoff of the derivative instrument is capped at 200, regardless of the price of IBM at the maturity date.

Therefore, the premium of this derivative security should be lower than the spot price of IBM, as the potential upside is limited.

To price the derivative instrument using a binomial tree, we first need to calculate the up and down factors:

u = e(σ * √Δt) = e(0.25 * √(3/6)) = 1.35914

d = 1/u = 0.73516

where σ is the volatility, Δt is the time step, and u and d are the up and down factors, respectively.

Next, we calculate the risk-neutral probability of an up move:

p = (e(r * Δt) - d) / (u - d) = (e(0.04 * 3/6) - 0.73516) / (1.35914 - 0.73516)

= 0.57348

Expected payoff at node (2, 1) = 200

Expected payoff at node (2, 2) = 44.16

Expected payoff at node (2, 3) = 44.16

Expected payoff at node (3, 1) = 57.76

Expected payoff at node (3, 2) = 57.76

Expected payoff at node (3, 3) = 32.04

Expected payoff at node (4, 1) = 75.68

Expected payoff at node (4, 2) = 44.16

Expected payoff at node (4, 3) = 32.04

Expected payoff at node (5, 1) = 108.36

Expected payoff at node (5, 2) = 57.76

Expected payoff at node (6, 1) = 158.28

Where r is the risk-free interest rate and p is the risk-neutral probability of an up move.

The expected payoff at each node can be calculated using the risk-neutral probabilities and the corresponding payoffs:

At node 5, the expected payoff is:

0.4575 * 0 + 0.5425 * (120 + 2 * (1.25 * 154 – 120)) = 212.80

At node 4, the expected payoff is:

0.4278 * 0 + 0.5722 * (120 + 2 * (1.25 * 136 – 120)) = 199.13

At node 3, the expected payoff is:

0.4008 * 0 + 0.5992 * (120 + 2 * (1.25 * 120 – 120)) = 185.58

At node 2, the expected payoff is:

0.3766 * 0 + 0.6234 * (120 + 2 * (1.25 * 105 – 120)) = 172.98

The correct inequality to represent the situation where everyone has to spend at least 10 dollars but less than 20 dollars in a gift exchange is 10 ≤ x < 20. (option b).

The correct inequality to represent the situation is B. 10 ≤ x < 20. This inequality reads "x is greater than or equal to 10, but less than 20". In other words, the amount of money each person spends (represented by x) must be at least 10 dollars, but cannot exceed 20 dollars.

To understand why this is the correct inequality, let's break it down. The symbol ≤ means "less than or equal to", and the symbol < means "less than". So, 10 ≤ x means "x is greater than or equal to 10", and x < 20 means "x is less than 20". Combining these two expressions gives us the inequality 10 ≤ x < 20, which represents the range of values that x can take on in this gift exchange.

Okay, let's solve this problem step-by-step:

1) To move the box initially, the applied force (F) must overcome static friction.

Static frictional force = F_static = μ_static * Weight of box

= 0.6 * 20kg * 10m/s^2

= 12N

So the minimum force to move the box is 12N.

2) Once the box is moving at a uniform velocity, the applied force only needs to overcome dynamic friction.

Dynamic frictional force = F_dynamic = μ_dynamic * Weight of box

= 0.5 * 20kg * 10m/s^2

= 10N

So to keep the box moving at a constant velocity, the applied force should be 10N.

In summary:

Minimum force to move the box (static friction) = 12N

Force to move at constant velocity (dynamic friction) = 10N

Using quadratic formula, the dimensions for the rectangular garden is 12 feet by 25 feet

a- To represent this situation with a quadratic equation, we can start by letting "x" represent the width of the planter in feet. According to the problem, the length of the planter is twice as long as the width plus one foot. Therefore, the length can be represented by the expression "2x + 1".

The area of a rectangle is given by the formula A = l x w, where A is the area, l is the length, and w is the width. In this case, we know that the total area of the planter is 300ft^2. Therefore, we can write the following quadratic equation to represent the situation:

A = l x w

300 = (2x + 1) * x

300 = 2x^2 + x

2x² + x - 300 = 0

b- To find the dimensions of Mrs. Greenthumb's garden, we can solve the quadratic equation 2x² + x - 300 = 0 for "x". We can use the quadratic formula, which states that for an equation of the form ax² + bx + c = 0, the solutions for x are given by:

x = (-b ± √(b^2 - 4ac)) / 2a

In this case, a = 2, b = 1, and c = -300. Therefore, we can plug these values into the quadratic formula and simplify to find the solutions:

x = (-1 ± √(1^2 - 4(2)(-300))) / 2(2)

x = (-1 ± √(1 + 2400)) / 4

x = (-1 ± √(2401)) / 4

We can simplify this expression further by noting that sqrt(2401) = 49. Therefore:

x = (-1 ± 49) / 4

The two solutions are:

x = 12 or x = -25/2

Since the width of the planter cannot be negative, we can discard the solution x = -25/2. Therefore, the width of the planter is x = 12 feet.

To find the length, we can use the expression for the length we found earlier: 2x + 1. Plugging in x = 12, we get:

length = 2x + 1 = 2(12) + 1 = 25

Therefore, the dimensions of Mrs. Greenthumb's garden are 12 feet by 25 feet.

True.

A 95% confidence interval for the population mean means that if we draw multiple samples from the same population and construct confidence intervals for the mean using each sample, then 95% of those intervals will contain the true population mean. This is because the confidence interval is computed based on the sample mean and the sample's standard deviation, which are random variables that are expected to vary from sample to sample. Therefore, we cannot be 100% certain that the true population mean is within any particular confidence interval, but we can be confident (95% confident, in this case) that most of the intervals we construct will contain the true mean. A 95% confidence interval for the population mean implies that if samples are drawn repeatedly and confidence intervals for μ are constructed, then 95% of the confidence intervals computed will contain the population mean. This means that you can be 95% confident that the true population mean lies within the calculated interval.

Answer: Plain:  the product is 24 ∠ 15° in polar form. This means that the magnitude of the product is 24 and the angle between the positive real axis and the line connecting the origin and the product is 15°, measured counterclockwise.

Step-by-step explanation: To multiply complex numbers in polar form, we multiply their magnitudes and add their angles. We can start by converting the given complex numbers from rectangular form to polar form:

6√5 - 6i = 6(√5 - i) = 12 ∠ -30°

(√3 + √3i) = √3(1 + i) = 2 ∠ 45°

where we have used the fact that ∠θ is the angle between the positive real axis and the line connecting the origin and the complex number a + bi, measured counterclockwise.

Now, we can multiply the two complex numbers in polar form:

(6√5 - 6i)(√3 + √3i) = 12 ∠ -30° * 2 ∠ 45°

= 24 ∠ 15°

Therefore, the product is 24 ∠ 15° in polar form. This means that the magnitude of the product is 24 and the angle between the positive real axis and the line connecting the origin and the product is 15°, measured counterclockwise.

To determine the quadrant of the complex plane in which the product lies, we note that the angle 15° is in the first quadrant (between 0° and 90°). Therefore, the product lies in the first quadrant of the complex plane.
