The three (3) statements which are true include the following:

A. The radius of the circle is 3 units.

B. The center of the circle lies on the x-axis.

D. The radius of this circle is the same as the radius of the circle whose equation is x² + y² = 9.

In Mathematics, the standard form of the equation of a circle is represented by this mathematical expression;

(x - h)² + (y - k)² = r²   ....equation 1.

Where:

From the information provided above, we have the following equation of a circle:

x² + y² – 2x – 8 = 0      ......equation 2.

In order to determine the true statements, we would rewrite the equation in standard form and then factorize by using completing the square method:

x² – 2x + y² = 8 = 0

x² – 2x + (2/2)² + y² = 8 + (2/2)²

x² – 2x + 1 + y² = 8 + 1

(x – 1)² + (y - 0)² = 9         .......equation 3.

Comparing equation 1 and equation 3, we have the following:

Center (h, k) = (1, 0)

Radius (r) = 3

Additionally, this line and the center of the given circle lies on the x-axis (x-coordinate) because the y-value is equal to zero (0).

(x – 0)² + (y - 0)² = 3²

x² + y² = 9.

About 99.7% of individuals have IQ scores in the interval 100 ± 3 ( 15 ) = [ 55 , 145 ] .

A total score obtained from a series of standardized tests or subtests created to gauge human intelligence is known as an intelligence quotient (IQ).  The psychologist William Stern created the abbreviation "IQ" for the German term Intelligent quotient, which he used to refer to a scoring system for intelligence tests at the University of Breslau that he promoted in a 1912 book.

In the past, a person's IQ was determined by dividing their mental age score—obtained after taking an intelligence test—by their chronological age, which was also stated in years and months. To get the IQ score, the resulting fraction (quotient) was multiplied by 100. The raw score for contemporary IQ tests is converted to a normal distribution with a mean of 100 and a standard deviation of 15.

In the given equation r = 2/5 t "r" is the dependent variable.

In mathematics, a variable is a symbol that represents a quantity that can take on different values. In many cases, variables can be divided into two types: dependent variables and independent variables.

An independent variable is a variable that can be changed freely, and its value is not dependent on any other variable in the equation.

A dependent variable is a variable whose value depends on the value of one or more other variables in the equation

Lin notices that the number of cups of red paint is always  2/5 of the total number of cups.

She writes the equation r = 2/5 t to describe the relationship.

In the equation, r = 2/5 t, "t" represents the total number of cups, while "r" represents the number of cups of red paint.

Here "t" is the independent variable because it represents the total number of cups, which can be changed arbitrarily.

The value of "r" depends on the value of "t" because the number of cups of red paint is always 2/5 of the total number of cups.

Fluff-ball can run at a speed of 4 meters per second.

Speed is a measure of how fast an object is moving. It is typically measured in units of distance per unit time, such as meters per second (m/s) or miles per hour (mph). Speed is a scalar quantity, meaning it has magnitude but no direction.

Fluff-ball can run at a speed of 4 meters per second.

This is because speed is equal to distance divided by time, and in this case the distance is 20 meters and the time is 5 seconds:

Speed = distance/time = 20 meters/5 seconds = 4 meters per second.

Therefore, Fluff-ball can run at a speed of 4 meters per second.

Information is needed to evaluate the project's financial viability, considering factors such as the initial investment, expected cash flows, cost of capital, and project duration.

To calculate the year 1 operating cash flows (OCF), we need to subtract the year 1 costs from the year 1 revenues:

OCF = Year 1 Revenues - Year 1 Costs

OCF = $192,000 - $125,000

OCF = $67,000

To find the depreciation expense in year 3, we need to determine the depreciation method. The provided information is incomplete regarding the depreciation method, so we cannot calculate the depreciation expense in year 3 without knowing the specific method.

The change in Net Working Capital (NWC) in year 2 can be determined by multiplying the Net Working Capital percentage (given as a percentage of t+1 revenues) by the year 1 revenues and subtracting the result from the year 2 revenues:

Change in NWC = (Year 2 Revenues - Net Working Capital percentage * Year 1 Revenues) - Year 1 Revenues

Without the specific Net Working Capital percentage or Year 2 Revenues values, we cannot calculate the exact change in NWC in year 2.

The net cash flow from salvage (ATSV) is calculated by multiplying the Salvage Value percentage by the Initial Cost:

ATSV = Salvage Value percentage * Initial Cost

ATSV = 28% * $390,000

ATSV = $109,200

the prime factors of 24 are 2 and 3, which combine to give the unique prime factorization of 24 as 2^3 × 3.

There are no factors of 24 that are prime numbers. A factor of a number is a whole number that divides that number without leaving a remainder. Prime numbers, on the other hand, are numbers that are divisible only by 1 and themselves, and cannot be expressed as the product of any other numbers.

The prime factors of 24 are 2, 2, and 3. We can factorize 24 as 2 × 2 × 2 × 3 or 2^3 × 3. Here, 2 and 3 are both prime numbers, but they are not factors of 24 in isolation. They are only prime factors of 24 when combined in the manner shown.

This fact highlights an important concept in number theory: the uniqueness of prime factorization. Every composite number can be expressed as a unique product of prime numbers. This fundamental theorem of arithmetic is crucial in many areas of mathematics, including cryptography, where it is used to secure communications and protect sensitive information.

The percentage of B5 produced from coconut oil is 0.045 X% of the imported diesel fuel. The percentage of E10 produced from molasses and cassava is 0.1143 Y% of the imported petrol.

To calculate the volume of B5 (a biodiesel blend of 5% biodiesel and 95% petroleum diesel) that can be produced from the coconut oil produced in Fiji, we need to know the total volume of coconut oil produced and the conversion efficiency of the trans-esterification process.

Let's assume that the volume of coconut oil produced in Fiji is X million litres, and the conversion efficiency is 90%. Therefore, the volume of biodiesel (CME) that can be produced from coconut oil is 0.9X million liters. Since B5 is a blend of 5% biodiesel, the volume of B5 that can be produced is 0.05 × 0.9X = 0.045X million liters.

To calculate the total volume of E10 (a gasoline blend of 10% ethanol and 90% petrol) that can be produced from the molasses and cassava, we need to know the total volume of molasses and cassava produced and the conversion efficiency of ethanol production.

Let's assume that the total volume of molasses and cassava produced is Y million liters, and the conversion efficiency is 80%. Therefore, the volume of ethanol that can be produced is 0.8Y million liters. Since E10 is a blend of 10% ethanol, the total volume of E10 that can be produced is 0.1 × 0.8Y = 0.08Y million liters.

The percentage of B5 produced from coconut oil is (0.045X / 100) × 100% = 0.045 X% of the imported diesel fuel.

The percentage of E10 produced from molasses and cassava is (0.08Y / 70) × 100% = 0.1143 Y% of the imported petrol.

Multiplicative inverse of 4 doesn't exist in modulo 30, 32, 33, and 34. It exists in modulo 31 and 35.

For a number to have a multiplicative inverse in modulo n, it must be relatively prime to n. Now let's find the multiplicative inverse of 4 modulo 30, 31, 32, 33, 34, and 35. In modulo 30, GCD(4, 30) = 2. Hence, 4 does not have a multiplicative inverse in modulo 30. In modulo 31, 4 and 31 are relatively prime. Therefore, the multiplicative inverse of 4 in modulo 31 is 8. Hence, 4 * 8 = 1 (mod 31). In modulo 32, GCD(4, 32) = 4. Therefore, 4 does not have a multiplicative inverse in modulo 32.

In modulo 33, GCD(4, 33) = 1. However, 33 is not a prime number. Therefore, it is not relatively prime to 4, and 4 does not have a multiplicative inverse in modulo 33.In modulo 34, GCD(4, 34) = 2. Hence, 4 does not have a multiplicative inverse in modulo 34.

In modulo 35, 4 and 35 are relatively prime. Therefore, the multiplicative inverse of 4 in modulo 35 is 9. Hence, 4 * 9 = 1 (mod 35). Therefore, we can conclude that the multiplicative inverse of 4 exists in modulo 31 and 35, and does not exist in modulo 30, 32, 33, and 34.

True. With similar triangles, the corresponding angles are equal. This property is one of the fundamental characteristics of similar triangles.

Similar triangles are triangles that have the same shape but possibly different sizes. They have corresponding angles that are equal, meaning that the angles in one triangle match the angles in the other triangle. This correspondence allows us to establish proportional relationships between the corresponding sides of the triangles.

The corresponding angles of similar triangles are equal because the angles are determined by the shape and orientation of the triangles, rather than their size. If two triangles have the same shape, their corresponding angles will be equal regardless of their size or position.

This property is the basis for many geometric proofs and calculations involving similar triangles. It allows us to solve problems involving proportions, ratios, and scaling.

By knowing that the corresponding angles of similar triangles are equal, we can confidently apply the principles of similarity to find missing side lengths, determine unknown angles, or establish relationships between different parts of the triangles.

The probability of being dealt a straight (but not a straight flush) in a 5-card poker hand is approximately 0.00392, when rounded to five decimal places. In conclusion, the probability is 0.00392.

The probability of being dealt a straight (but not a straight flush) in a 5-card poker hand can be calculated as follows:

First, we need to determine the number of possible straights. There are 10 possible straights (A-2-3-4-5, 2-3-4-5-6, etc.) in a deck of 52 cards.

Next, we need to determine the number of ways to choose the suits for each card in the straight. For each card in the straight, there are 4 possible suits. So, there are \(4^5\) = 1024 ways to choose the suits for the cards in the straight.

Finally, we divide the number of ways to get the desired hand by the total number of possible 5-card hands: (10 * 1024) / (choose(52,5)) = 0.00392.

Therefore, the probability of being dealt a straight (but not a straight flush) in a 5-card poker hand is approximately 0.00392, when rounded to five decimal places. In conclusion, the probability is 0.00392.
