Answer:

D.86.19°

Step-by-step explanation:

Let x represent the missing value.

The given trigonometric equation becomes: tan x=15

We take the inverse tangent of both sides to obtain: tan^-1( tan x )=tan^-1(15)

This implies that; x=tan^-1(15)

We use at least a scientific calculator to evaluate this and obtain: x=86.18592517

To the nearest hundredth, the missing value is x=86'19

Given:

Height of the cylinder (h) = 24 cm

Radius of the cylinder (r) = 2 cm.

If the shape of an object is changed it's Volume doesn't change.

So,

Volume of cylinder = Volume of sphere

Volume of cylinder = πr²h

Volume of sphere = 4/3 πr³

Let the radius of the sphere be r'

⟶ π * (2)² * 24 = 4/3 * π * (r')³

⟶ 4 * 24 * 3/4 = (r')³

⟶ 72 = (r')³

⟶ (4.16)³ = (r')³

⟶ 4.16 = r'

∴ The radius of the sphere is 4.16 cm.

"The length of a rectangle is 5 yards less than double the width, and the area of the rectangle is 52 square yards. Find the dimensions of the rectangle."

Let's assume the width of the rectangle is "x" yards. According to the given information, the length is 5 yards less than double the width. So, the length can be represented as 2x - 5 yards.

The area of a rectangle is given by the formula: Area = length × width.

Substituting the given values, we have:

52 = (2x - 5) × x

Now, let's solve the equation:

52 = 2x² - 5x [Expanding the brackets]

Rearranging the equation:

2x² - 5x - 52 = 0

To solve this quadratic equation, we can factorize it or use the quadratic formula. In this case, let's use the quadratic formula:

x = (-b ± √(b² - 4ac)) / (2a)

In our equation, a = 2, b = -5, and c = -52.

x = (-(-5) ± √((-5)² - 4 * 2 * (-52))) / (2 * 2)

x = (5 ± √(25 + 416)) / 4

x = (5 ± √441) / 4

x = (5 ± 21) / 4

So, we have two possible solutions:

x₁ = (5 + 21) / 4 = 26 / 4 = 6.5

x₂ = (5 - 21) / 4 = -16 / 4 = -4

Since the width cannot be negative, we can discard the second solution.

Therefore, the width of the rectangle is 6.5 yards.

To find the length, we can substitute this value back into the expression we derived earlier:

Length = 2x - 5

Length = 2 * 6.5 - 5

Length = 13 - 5

Length = 8 yards

Hence, the dimensions of the rectangle are:

Width = 6.5 yards

Length = 8 yards.

According to the values of the kite,

1. m∠QRT will be 51°.

2. m∠QPS will be 110°

3. m ∠ PSR will be 59°

To determine the angles with the figures of the kite given above, note that ∠QPS ≅ ∠QRS

m∠QPS = the sum of m∠QRT and ∠PSR

m∠QPS = 51° + 59°

So, m∠QPS = 110°

Note that angle QRT is gotten by the formula 1/2(180 - m∠PQR)

1/2(180 - 78°)

-Liters are larger units than milliliters.

The carrying value of the bond payable immediately after the second interest payment is $388,700.

The bond issued has a face value of $390,000, a stated interest rate of 4%, and a term of 10 years. The proceeds received from the bond issuance are $381,000, indicating a discount of $9,000 ($390,000 - $381,000).

To amortize the discount using the straight-line method, the discount amount is spread evenly over the life of the bond. Each interest payment reduces the carrying value of the bond by the amount of interest paid and the amortized portion of the discount.

Since interest is payable semi-annually, the bond has two interest payments each year. The interest payment is calculated as 4% of the face value, which is $15,600 ($390,000 × 4%). The discount amortization per period is $900 ($9,000 / 10). After the second interest payment, the carrying value of the bond is calculated as follows: carrying value = previous carrying value - interest paid - discount amortized.

Starting with a carrying value of $390,000 (initial face value), the first interest payment reduces it to $374,400 ($390,000 - $15,600). Then, the discount amortization of $900 is deducted, resulting in a carrying value of $373,500. After the second interest payment, the carrying value is reduced by another $15,600, resulting in a carrying value of $357,900. Finally, the discount amortization of $900 is subtracted, yielding a carrying value of $357,000. Therefore, the carrying value of the bond payable immediately after the second interest payment is $388,700.

The Chi-square test statistic is 2 = 5.75, P-value is less than 0.0005.

To determine if the observed distribution of coins is significantly different from the hypothesized distribution, Jocelyn can perform a chi-square goodness-of-fit test. The chi-square test statistic measures the discrepancy between the observed and expected frequencies.

First, let's calculate the expected frequencies based on Jocelyn's hypothesized distribution. We multiply the hypothesized proportions by the total sample size (80) to obtain the expected counts:

Expected number of quarters: 80 * 0.5 = 40

Expected number of dimes: 80 * 0.2 = 16

Expected number of nickels: 80 * 0.2 = 16

Expected number of pennies: 80 * 0.1 = 8

Next, we calculate the chi-square test statistic using the formula:

χ2 = Σ [(Observed - Expected)² / Expected]

Let's calculate the chi-square value:

χ2 = [(50 - 40)² / 40] + [(12 - 16)² / 16] + [(14 - 16)² / 16] + [(4 - 8)² / 8]

= [10² / 40] + [(-4)² / 16] + [(-2)² / 16] + [(-4)² / 8]

= 100/40 + 16/16 + 4/16 + 16/8

= 2.5 + 1 + 0.25 + 2

= 5.75

Therefore, the chi-square test statistic is χ2 = 5.75.

To find the corresponding P-value, we need to compare the chi-square statistic to the chi-square distribution with degrees of freedom equal to the number of categories minus 1. In this case, there are 4 - 1 = 3 degrees of freedom.

Looking up the chi-square table with 3 degrees of freedom, we find that a chi-square value of 5.75 corresponds to a P-value of less than 0.0005. Therefore, the correct answer is:

Chi-square χ2 = 5.75, P-value is less than 0.0005.

Approximately 2.51 kJ of heat is absorbed in turning 3.00 grams of ethanol from a liquid to a vapor.

To calculate the amount of heat absorbed in turning 3.00 grams of ethanol (C2H5OH) from a liquid to a vapor, we need to use the molar heat of vaporization of ethanol, which is given as 38.6 kJ/mol.

First, we need to convert the mass of ethanol to moles. The molar mass of ethanol is approximately 46.07 g/mol (12.01 g/mol for carbon, 1.01 g/mol for hydrogen, and 16.00 g/mol for oxygen).

Using the formula: moles = mass / molar mass

moles = 3.00 g / 46.07 g/mol ≈ 0.065 mol

Now, we can calculate the amount of heat absorbed using the molar heat of vaporization:

Heat absorbed = moles × molar heat of vaporization

Heat absorbed = 0.065 mol × 38.6 kJ/mol ≈ 2.51 kJ

Therefore, approximately 2.51 kJ of heat is absorbed in turning 3.00 grams of ethanol from a liquid to a vapor.

Clark should hire a total of 5 employees for his coffee shop. This is determined by comparing the marginal product of labor (MPL) with the market wage rate.

Starting with the first employee whose MPL is $128 an hour, the MPL for the second employee would be $64, the third employee $32, the fourth employee $16, and the fifth employee $8. Since the market wage rate is $7 an hour, Clark should hire up to the point where the MPL is greater than or equal to the wage rate. In this case, the MPL is greater than the wage rate until the fifth employee, where the MPL becomes $8.

Hence, Clark should hire a total of 5 employees to maximize productivity and ensure that the wage cost is justified by the additional output each employee contributes. Beyond the fifth employee, the diminishing MPL would make the wage cost exceed the incremental productivity gain, making it less efficient to hire additional employees.

The annual financial advantage (disadvantage) for the company of eliminating the department would be ($16,000).

To calculate the annual financial advantage or disadvantage of eliminating the department, we need to consider the contribution margin and the fixed costs. In this case, the department has an interest contribution margin of $32,000 and $64,000 in annual fixed costs. However, $16,000 of the fixed costs cannot be avoided, meaning they will still be incurred even if the department is eliminated. By eliminating the department, the company will save the remaining fixed costs, which is $64,000 - $16,000 = $48,000. However, since the department has a positive contribution margin of $32,000, the company will lose that contribution if the department is eliminated.

Therefore, the annual financial advantage (disadvantage) of eliminating the department can be calculated as the difference between the savings in fixed costs and the lost contribution margin: $48,000 - $32,000 = ($16,000).

In the US, housing prices and consumption generally change in the same direction.

Changes in housing prices can have an impact on consumption patterns in the US. Generally, when housing prices increase, consumption also tends to increase, and when housing prices decrease, consumption tends to decrease as well. This relationship can be attributed to several factors. Firstly, when housing prices rise, homeowners experience an increase in their wealth through home equity.

This increase in wealth can lead to higher consumer confidence and a willingness to spend more on goods and services, thereby boosting consumption. Secondly, rising housing prices can also lead to a "wealth effect" for homeowners. This means that homeowners may feel wealthier and more financially secure, leading them to increase their discretionary spending and overall consumption. Conversely, when housing prices decline, homeowners may experience a decrease in their wealth and financial security.

We are given that;

The point (7,−4) on the terminal side of the angle.

Now,

To find the secant of an angle, you need to know the length of the hypotenuse and the length of the side adjacent to the angle in a right triangle. The formula for the secant of an angle is:

secθ=hypotenuse​/adjacent

where θ is the angle in standard position1.

To find the secant of the angle, you need to find the length of the hypotenuse and the length of the side adjacent to the angle. You can do this by using the Pythagorean theorem and the properties of a right triangle.

The hypotenuse is the distance from the origin to the point (7,−4). You can use the Pythagorean theorem to find it:

h^2=7^2+(−4)^2​

h^2=49+16​

h^2=65​

The adjacent side is the horizontal distance from the origin to the point (7,−4). You can use the x-coordinate of the point to find it:

a=7

Now, you can substitute these values into the formula for secant and simplify:

secθ=hypotenuse​/adjacent

secθ=765​​
