We can use trigonometry to find the length of side SU in triangle TSU. We can use the tangent function, where tangent is equal to the opposite side divided by the adjacent side. In this case, the opposite side is SU and the adjacent side is ST.

What is basic trigonometry?

The study of the relationship between the sides and angles of the right-angle triangle is the main objective of the field of mathematics known as "trigonometry." Trigonometric formulas, functions, or identities can consequently be used to determine the missing or unknowable angles or sides of a right triangle.

We know that angle TUS is 37 degrees, so we can use that angle to find the tangent of the angle:

tan(37) = SU / 0.6

Solving for SU:

SU = 0.6 * tan(37)

The exact length of SU can be found by using a calculator or a table of trigonometric values. To a good approximation, the value of SU is approximately 0.73.

A. The current account balance is a deficit of 130

B. The financial account balance is a deficit of 70

C. The trade balance is a deficit of 50.

D. The net factor payments are a deficit of 30.

Balance of payments is the method by which countries measure all of the international monetary transactions within a certain period.

(a) The current account balance can be calculated as follows:

Current Account Balance = (Exports of goods + Service exports) - (Imports of goods + Service imports + Income payments to foreigners - Income receipts from abroad)

= (275 + 50) - (325 + 40 + 70 - 40)

= 325 - 455

= -130

So, the current account balance is a deficit of 130.

(b) The financial account balance can be calculated as follows:

Financial Account Balance = Increase in home country assets abroad - Increase in foreign assets in home country

= 350 - 420

= -70

So, the financial account balance is a deficit of 70.

(c) The trade balance can be calculated as follows:

Trade Balance = Exports of goods - Imports of goods

= 275 - 325

= -50

So, the trade balance is a deficit of 50.

(d) The net factor payments can be calculated as follows:

Net Factor Payments = Income receipts from abroad - Income payments to foreigners

= 40 - 70

= -30

So, the net factor payments are a deficit of 30.

Let U be the set representing the number of commuters in New york.

⇒n(U) = 1900

Let A be the set representing the commuters take subway

The amount of the sales tax is $9.75.

The percentage is defined as a ratio expressed as a fraction of 100.

The taxable amount of the sale: $150

Sales tax percentage: 6.5%

To calculate the sales tax, you can multiply the taxable amount of the sale by the sales tax percentage.

Sales Tax = Taxable Amount × Sales Tax Percentage

Sales Tax = $150 × 6.5%

Sales Tax = $150 × 0.065

Apply the multiplication operation, and we get

Sales Tax = $9.75

So, the amount of the sales tax is $9.75.

Step-by-step explanation:

The complete equation is 2Fe(s) + 3Cl₂(g) -> 2FeCl₃(s) ΔH = -400 kJ

A thermochemical equation is a chemical equation that includes information about the energy change that occurs during a chemical reaction. The energy change is represented by the symbol ΔH (delta H), which stands for the change in enthalpy, or heat energy, of the system. The equation shows the reactants on the left side and the products on the right side, and includes the amount of heat energy evolved or absorbed during the reaction.

For example, consider the reaction:

2H2(g) + O2(g) → 2H2O(l) ΔH = -571 kJ/mol

This equation shows that two molecules of hydrogen gas react with one molecule of oxygen gas to form two molecules of liquid water. The reaction releases 571 kJ of heat energy per mole of hydrogen and oxygen that react.

The complete thermochemical equation for the reaction of Fe(s) with Cl₂(g) to form FeCl₃(s) is:

2Fe(s) + 3Cl₂(g) -> 2FeCl₃(s) ΔH = -400 kJ

This means that the reaction releases 400 kJ of energy for each mole of Fe(s) that reacts. The negative sign indicates that the reaction is exothermic, meaning it releases heat.

There is a connection between one set of values about one variable and an other number of values. direct variation With the equations y = mx + b, you have the direct variant function y = mx (often written y = kx). Equations that describe the relation between independent variables in a language also explain how those variables vary between one another. There are various types of variations, including linear, inverse, joint, among combination variations. If y and x are said to be directly connected, then y must equal kx, where k is a number that is every now and again referred to as the perpetual of variation. If y and x have such an inverse connection, then y equals k/x, where k is just the variance constant.

Step-by-step explanation:

The use of the commutative property of addition is illustrated by option D: (9x + 5y) + 2z = (5y + 9x) + 2z.

The commutative property of addition states that the order of addition does not affect the sum. In other words, changing the order of the addends does not change the result. Option D demonstrates this property by showing that adding 9x and 5y to 2z is the same as adding 5y and 9x to 2z. The result is the same regardless of the order in which the addends are combined.

The value of x such that the probability of the sample mean being between 13.6-0.89 and 13.6+0.89 is 0.6827 is approximately x = 0.89.

Central Limit Theorem states that as the sample size increases the distribution of the sample means approaches a normal distribution with a mean equal to the population mean and a standard deviation equal to the population standard deviation divided by the square root of the sample size.

Therefore, for a sample of 8 two-lined salamanders, the standard deviation of the sample means is:

σ = σ/√n = 2.2/√8 = 0.89

We are looking for the value of x such that the probability of the sample mean being between 13.6-x and 13.6+x is 0.6827. This corresponds to the area under the normal curve within x standard deviations of the mean.

We can use a standard normal table or calculator to find the value of x corresponding to 0.6827. The result is approximately x = 0.89.

So, the value of x such that the probability of the sample mean being between 13.6-0.89 and 13.6+0.89 is 0.6827 is approximately x = 0.89.

By applying probability concept, it can be concluded that the experimental probability of rolling each is P(1) = 1/6, P(2) = 1/7,  P(3) = 1/3,  P(4) = 2/21,  P(5) = 1/7, and P(6) = 5/42.

Probability is a value used to measure the degree of occurrence of a random event.

P(E) = n(E)/n(S)

n(E) = number of desired events

n(S) = total number of events

We have the following information about a die rolling 42 times:

One    Two    Three   Four     Five     Six

 7          6          14         4          6        5

The theoretical probability of rolling any number on a six-sided die is  7/42 or 1/6.

Now we can calculate the probability of each side by substituting the value in the table into the equation:

P(E) = n(E)/n(S)

P(1) = 7/42

      = 1/6

P(2) = 6/42

      = 1/7

P(3) = 14/42

      = 1/3

P(4) = 4/42

      = 2/21

P(5) = 6/42

      = 1/7

P(6) = 5/42

Thus, the experimental probability of rolling each is P(1) = 1/6, P(2) = 1/7,  P(3) = 1/3,  P(4) = 2/21,  P(5) = 1/7, and P(6) = 5/42.

A plane is a two-dimensional, flat surface that never ends in mathematics. A plane is a two-dimensional equivalent of a three-dimensional equivalent that contains three spatial dimensions, a line, and a point. Planes can resemble subspaces in some higher-dimensional situations, as if the room's walls had been substantially stretched. These walls have their own existence, exactly as in the context of Euclidean geometry.

A flat surface in three dimensions can be represented using the plane equation. There are several approaches for determining the equation for a given function.. The equation for the plane can be expressed in either cartesian form or vector form.

Hence, the general form of the equation is A(x−x1)+B(y−y1)+C(z−z1)=0

Now,

For given two points in (x1,y1),(x2,y2) in coordinate plane

distance between them will be = √((x2-x1)²+(y2-y1)²)

If the price of avocados increases by 11% for four consecutive months, then the price of avocados did not increase by 44% over the four-month period. The calculation of percentage increase is cumulative, meaning that the increase in price in the second month will be based on the increased price from the first month, and so on.

In this case, if the price starts at $1 and increases by 11% each month, the price after four months will be $1 * 1.11 * 1.11 * 1.11 * 1.11 = $1.4864, which represents an increase of 48.64% over the four-month period, not 44%.
