The measure of angle C is given as follows:

C = 106.6º.

The Law of Cosines is a trigonometric formula that relates the lengths of the sides of a triangle to the cosine of one of its angles. It is also known as the Cosine Rule.

The Law of Cosines states that for any triangle with sides a, b, and c and angle C opposite to side c, the following equation holds true:

c^2 = a^2 + b^2 - 2ab cos(C)

The side of length 9 is opposite to the angle C, hence the equation is given as follows:

9² = 4² + 7² - 2 x 4 x 7 x cos(C)

56cos(C) = -16

cos(C) = -16/56

C = arccos(-16/56)

C = 106.6º.

The value of the angle C of the given triangle using law of cosines is: C = 106.6°

We usually make use of the Law of Cosines, if only one of which is missing: three sides and one angle. Thus, if the known properties of the triangle is SSS(side-side-side) or SAS (side-angle-side), this law is applicable.

This could be in the form of:

c² = a² + b² - 2ab Cos C

From the given triangles, we have:

a = 4

b = 7

c = 9

Thus:

9² = 4² + 7² - 2(4 * 7)cos C

81 = 16 + 49 - 56 cos C

56 cos C = -16

cos C = -16/56

cos C = -0.2857

C = cos⁻¹0.2857

The key features of the sinusoidal function are calculated below

The function y = tan(1/3x) is a tangent function with a period of π/b, where b is the coefficient of x in the argument of the tangent function.

In this case, b = 1/3, so the period is π/(1/3) = 3π.

The interval for the principal cycle is the range of x-values that produce one complete cycle of the tangent function.

Since the tangent function has vertical asymptotes at x = (2n+1)π/2 for all integers n, we can find the interval for the principal cycle by finding the smallest interval that contains one complete cycle and does not contain any vertical asymptotes.

To find the interval for the principal cycle, we first note that the tangent function has a vertical asymptote at x = π/2.

Therefore, we can start the interval at x = π/2 and then move to the right until we complete one cycle and reach the next vertical asymptote.

Since the period is 3π, the next vertical asymptote is at x = π/2 + 3π = 7π/2.

Therefore, the interval for the principal cycle is [π/2, 7π/2].

To find the equations of the vertical asymptotes, we use the formula x = (2n+1)π/2 for all integers n.

Therefore, the equations of the vertical asymptotes are x = π/2 + nπ for all integers n.

The center point of the principal cycle is the midpoint between the x-values of the endpoints of the interval.

Therefore, the center point is (π/2 + 7π/2)/2 = 4π/2 = 2π.

The halfway points of the principal cycle are the points where the tangent function takes on half of its maximum and minimum values.

Since the maximum and minimum values of the tangent function are ±∞, we can instead find the points where the tangent function is zero.

The tangent function is zero at x = nπ for all integers n, so the halfway points of the principal cycle are (π, 0) and (3π, 0).

The number of scoops of seeds needed to fill three bird feeders is 13 1/7 scoops of seeds .

To calculate the total seed quantity required to fill all three feeders, begin by computing the volume for the first two dispensers: each can hold 5 and five-twelfths cups of seeds.

Next, this text assumes an understanding that one scoop of seeds holds approximately 1 and one-sixth cups of product. Using this information, we determine how many scoops are needed to satisfy all three bird feeders' capacity.

By multiplying the first fraction's value with the reciprocal of the second fraction helps you divide fractions accurately:

(46 / 3) x (6 / 7) = (46 x 6) / (3 x 7) = 276 / 21

The size of the payments that must be deposited at the beginning of each 6-month period in an account that pays 9.6%, compounded semiannually, is PMT ≈ $1,757.23

FV = PMT * [(1 + r)^nt - 1] / r

(1 + r)^nt = (1 + 0.048)^(2 * 19)

Biodiesel is not commonly used as a fuel source for electricity generation, so changes in its production would not significantly affect the overall supply and demand of electricity.

The area of the figure is 45 square millimeters.

What is Area?

Area is a measure of the size or extent of a two-dimensional surface or shape. It is usually expressed in square units such as square meters , square feet , square centimeters , square inches , etc. The area of a shape or surface can be calculated by multiplying the length of one side or dimension by the length of an adjacent side or dimension, or by using specific formulas depending on the shape.

The figure can be broken down into a rectangle (5 mm x 7 mm) and two right triangles (with legs 2 mm and 3 mm, respectively).

Area of rectangle = length x width = 5 mm x 7 mm = 35 square mm

Area of each triangle = 1/2 x base x height = 1/2 x 2 mm x 4 mm = 4 square mm

1/2 x 3 mm x 4 mm = 6 square mm

Total area of the figure = area of rectangle + area of two triangles = 35 square mm + 4 square mm + 6 square mm = 45 square mm.

Therefore, the area of the figure is 45 square millimeters.

Out of the 9 pieces, only the pieces on the outer edge will have exactly one frosted side.

If we count the number of pieces on the outer edge, we can determine how many pieces are frosted on only one side.

For a cube-shaped cake, there are 8 pieces on the outer edge.

To see why, imagine slicing off the corners of the cube to create a smaller cube inside.

Each of the 6 faces of the smaller cube will have a piece missing from the corner.

Therefore, there are 6 pieces on the outer edge of the larger cube, and each of these pieces can be divided into two smaller pieces (with one frosted side each) by cutting along the diagonal.

This gives a total of 12 pieces, but we need to subtract the 4 corner pieces that have two frosted sides each.

If glass contains 320 cm³ of milk, the mass of the milk is 330 g, the density of the milk is approximately 1031 kg/m³.

Density is defined as the mass per unit volume of a substance. To find the density of milk in kg/m³, we need to convert the given volume and mass to the appropriate units.

First, we need to convert the volume from cm³ to m³. Since 1 m = 100 cm, 1 m³ = (100 cm)³ = 1,000,000 cm³. Therefore, we can convert 320 cm³ to m³ by dividing by 1,000,000:

320 cm³ ÷ 1,000,000 = 0.00032 m³

Next, we need to convert the mass from grams to kilograms. Since 1 kg = 1000 g, we can convert 330 g to kg by dividing by 1000:

330 g ÷ 1000 = 0.33 kg

Now that we have both the mass and volume in appropriate units, we can calculate the density by dividing the mass by the volume:

Density = mass ÷ volume = 0.33 kg ÷ 0.00032 m³ ≈ 1031 kg/m³

The value of arctan(√2) for the equation tan(x/2 - π/2) = √2 in the form x=π +πn is given by arctan(√2) = π/4 + πn, where n is an integer.

Equation is equal to,

tan(x/2 - π/2) = √2

By using the identity for tangent of half angle,

tan(x/2 - π/2)

= 1/cot(x/2 - π/2)

= 1/(-tan(x/2))

So the equation becomes,

1/(-tan(x/2)) = √2

Multiplying both sides by -1, we get,

tan(x/2) = -1/√2

            = -√2/2

Now use the inverse tangent function (arctan) to find x/2,

arctan(-√2/2) = -π/4

Since x/2 - π/2 = -π/4, we have,

⇒ x/2 = -π/4 + π/2

         = π/4

The solutions for x are x = π/2 + 2πn, where n is an integer.

Now let us find the value of arctan(√2),

arctan(√2) is the angle whose tangent is √2.

Since tan(π/4) = √2, we have,

arctan(√2) = π/4 + πn, where n is an integer.

Therefore, the value of arctan(√2) in the form x=π +πn is equal to

arctan(√2) = π/4 + πn, where n is an integer.

To find the total of the debit side of the unadjusted trial balance,

We need to add up the debit balances of all the accounts listed.

i.e

Accounts Receivable, Cash, Common Stock, Equipment, Insurance Expenses, Land, Notes Receivable, Prepaid Insurance, Rent Expenses, Salaries, and Wages Expense are all debit accounts.

Notes Payable is a credit account, so we subtract it from the total.

Service Revenue and Retained Earnings do not have balances, as they are not accounts that are included in the trial balance.

Now,

The total of the debit side of the unadjusted trial balance is:

The three line fragments are known as the sides of the triangle, while the three places where they converge are known as the vertices of the triangle.

Let suppose, base of the triangle = x

Then, according to the problem, the height of the triangle is x - 3.

We know the area of triangle is,

[tex]A = \frac{1}{2}*b*h[/tex]  ;   here A is the area, h is the height and b is the base.

Put the given values,

[tex]90 = \frac{1}{2} *(x)*(x-3)[/tex]

Multiplying both sides by 2:

180 = x² - 3x

x² - 3x - 180 = 0

(x - 15)(x + 12) = 0

Therefore, either x - 15 = 0 or x + 12 = 0.

If x - 15 = 0, then x = 15, which is the length of the base of the triangle.

If x + 12 = 0, then x = -12, which is not a valid solution since the length of a side of a triangle cannot be negative.

Therefore, the length of the base of the triangle is 15 feet.
