Taking the quotient between the total distance and the gallons consumed we can see that:

Mpg = 37 miles per gallon.

It is just given by the quotient between the number of miles traveled and the number of gallons used.

We know that at the start the odometer reads 69247 miles and at the end the odometer reads 69765 miles, taking the difference we can see that the total distance traveled is:

69765 mi - 69247 mi = 518 mi

And you consumed 14 gallons of gas, then the miles per gallon is:

Mpg = 518mi/14 gal = 37 miles per gallon.

2x(5x + 1) / (4x - 1) is the final expression.

Option D is the correct answer.

An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.

Example: 2 + 3x + 4y = 7 is an expression.

We have,

(4x³ - 12x²) / (4x² + 7x - 2) / (2x² - 6x) / (5x² + 11x + 2)

= (4x³ - 12x²) x (5x² + 11x + 2) / (4x² + 7x - 2) x (2x² - 6x)

Now,

(4x³ - 12x²) = 4x² (x - 3) _____(1)

And,

(5x² + 11x + 2)

Middle term factorizing

= 5x² + (10 + 1)x + 2

= 5x² + 10x + x + 2

= 5x (x + 2) + 1(x + 2)

= (x + 2) (5x + 1) ______(2)

And,

(4x² + 7x - 2)

Middle term factorizing

= 4x² + (8 - 1)x - 2

= 4x² + 8x - x - 2

= 4x(x + 2) - 1(x + 2)

= (4x - 1) (x + 2) ______(3)

And,

(2x² - 6x) = 2x (x - 3) ______(4)

From (1), (2), (3), and (4) we get,

(4x³ - 12x²) x (5x² + 11x + 2) / (4x² + 7x - 2) x (2x² - 6x)

= [ 4x² (x - 3) x (x + 2) (5x + 1) ] / [ (4x - 1) (x + 2) x 2x(x - 3) ]

(x + 2) and (x - 3) gets canceled.

= [4x² (5x + 1)] / [(4x - 1) 2x]

= 2x(5x + 1) / (4x - 1)

Thus,

2x(5x + 1) / (4x - 1)

Step-by-step explanation:

A supernova is a powerful and luminous explosion of a star, which is what the sun is.

Therefore, the values of x that make the equation distance between (11,6) and (x,-9) equal to 17 are x = 19 and x = 3.

The formula y=mx+b is used to draw a simple regression graph. The inclination is B, and the y-intercept is m. It is frequently referred to simply as a "simple method combining many variables," despite the fact that the section before it is divided into distinct sections. Bivariate linear equations have two variables. For problems involving linear equations in applications, there are no proven solutions. Y=mx+b, also known as mx+b, provides a number of straightforward formulae.

Here,

Using the distance formula:

sqrt((x - 11)^2 + (-9 - 6)^2) = 17

Simplifying:

sqrt((x - 11)^2 + 225) = 17

Squaring both sides:

(x - 11)^2 + 225 = 289

(x - 11)^2 = 64

Taking the square root:

x - 11 = ±8

x = 11 + 8 or x = 11 - 8

x = 19 or x = 3

Therefore, the values of x that make the equation distance between (11,6) and (x,-9) equal to 17 are x = 19 and x = 3.

The difference quotient for the function f(x) = 3x² - x + 4 is:

(f(x+h) - f(x)) / h

= ((3(x+h)² - (x+h) + 4) - (3x² - x + 4)) / h

= (3x² + 6xh + 3h² - x - h + 4 - 3x² + x - 4) / h

-4x + 2y = 13

We can use either substitution or elimination method. Here we'll use the elimination method:

Multiplying the first equation by 2, we get:

4x + 2y = 16

Adding this equation to the second equation, we eliminate y and get:

The frequency of the wave is f = 0.67 hertz.

What is the frequency?

Frequency is the number of occurrences of a repeating event per unit of time.

1) The velocity of the wave can be calculated using the formula v = lambda / T, where lambda is the wavelength and T is the time period.

From the wave function, the wavelength can be determined by finding the distance between consecutive crests or troughs of the wave,

which is given by

2 * π / (5 * π / 6) = (2/5) * (6/π) m.

The time period can be determined by finding the time it takes for one complete wave cycle to occur, which is given by 2*π / (3 * π / 7) = (2/3) * (7/π) s.

So, the velocity of the wave is v = (2/5) * (6/π) m / ((2/3) * (7/π) s) = (12/15) * (6/7) * (π/π) m/s = 4/5 m/s.

2) The time period of the wave can be calculated as T = 2*π / (3 * π / 7) = (2/3) * (7/π) s.

3) The wavelength of the wave can be calculated as lambda = 2*π / (5 * π / 6) = (2/5) * (6/π) m.

4) The frequency of the wave can be calculated using the formula f = 1 / T, where T is the time period.

f = 1 / ((2/3) * (7/π) s) = (3/2) * (π/7) Hz

f = 0.67 hertz

Hence, the frequency of the wave is f = 0.67 hertz.

A wave function, in physics, is a mathematical description of a wave, usually used in quantum mechanics to describe the behavior of subatomic particles such as electrons and protons. The wave function provides information about the position, momentum, and other properties of a particle at a given point in time and space. It is represented by a complex mathematical function that satisfies Schrödinger's equation, which describes the time evolution of a wave function in a quantum system. The wave function is central to the interpretation of quantum mechanics and is often used to calculate the probabilities of different outcomes in quantum experiments.

Given the wave function:

y(x, t) = 0.75 m × sin[(5 × π / 6 m⁻¹) × x - (3 × π / 7 s⁻¹) × t + π / 5]

The velocity of the wave can be calculated using the wavelength (λ) and frequency (f) of the wave. The velocity (v) is given by v = λ × f. The wavelength (λ) and frequency (f) can be determined from the wave function as follows:

λ = 2 × π / (5 × π / 6 m⁻¹) = 6 / 5 m

f = 3 × π / 7 s⁻¹

So, the velocity of the wave is given by:

v = λ × f = (6 / 5 m) × (3 × π / 7 s⁻¹) = (6 × 3 × π / (5 × 7)) m/s = (6 × π / 35) m/s

The time period (T) of the wave is the time it takes for the wave to complete one full cycle. It can be determined from the frequency of the wave as follows:

T = 1 / f = 1 / (3 × π / 7 s⁻¹) = 7 / (3 × π) s

The wavelength (λ) of the wave has already been calculated in step 1 as λ = 6 / 5 m

The frequency (f) of the wave has already been calculated in step 1 as f = 3 × π / 7 s⁻¹

So, the velocity of the wave is (6 × π / 35) m/s, the time period of the wave is 7 / (3 × π) s, the wavelength of the wave is 6 / 5 m, and the frequency of the wave is 3 × π / 7 s⁻¹.

Step-by-step explanation:

The rate at which a particular animal grows is proportional to the difference between its adult height and current height. As the animal grows, the difference between the adult height and current height decreases. T

Therefore the rate of growth decreases. This is because, as the animal grows, it reaches a point where it cannot grow any taller and the rate of growth slows down. In other words, the rate of growth is proportional to the difference between the adult's height and current height. the rate of growth is also related to the age of the animal.

Younger animals tend to grow faster than older animals because their adult height is still far away, so the difference between their current height and adult height is greater.As the animal gets older and closer to its adult height, the rate of growth decreases.

furthermore, the rate of growth is also affected by the animal's diet and overall health. If the animal is malnourished or unhealthy, then its rate of growth will be slower than if it had a healthy diet and lifestyle.

The two angles are 32 degrees and 48 degrees.

Step-by-step explanation:

If one angle of a triangle is 100 degrees, then the sum of the other two angles is 80 degrees (180 - 100). If the magnitude of the other two angles is in the ratio 2:3, then we can call the first angle 2x and the second angle 3x. The sum of these two angles is 5x, so 5x = 80, and x = 16. So, the two angles are 2x = 32 degrees and 3x = 48 degrees.
