There is no error in steps while proving 2=1

We have to prove 2=1

Let x=1

Add X on both sides

X+X = 1+X

2x = 1+X

2x = X+1

Subtract 2 from both sides

2X-2 = X+1-2

2x-2 = X-1

2(X-1)=x-1

Divide both sides by x-1

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

We get 2=1

Hence, while proving 2=1 there is no error in steps

Answer:

First, we need to convert 15 American dollars to Euro:

15 USD * 17.1 Euro/USD = 256.5 Euro

Then, we can use the exchange rate between Euro and Dominican Pesos to convert Euro to Dominican Pesos:

1 Euro = 435.2 Dominican Pesos/7 Euro

Therefore, 256.5 Euro = (256.5/7) * 435.2 Dominican Pesos = 9,475.2 Dominican Pesos

Finally, we can use the proportion:

12 USD / 15 USD = x Dominican Pesos / 9,475.2 Dominican Pesos

Solving for x, we get:

x = (12/15) * 9,475.2 = 7,580.16 Dominican Pesos

Therefore, 12 American dollars is worth 7,580.16 Dominican Pesos.

Answer: Broken Math Problem

Step-by-step explanation:

The general form of the function is:

y = A sin(Bx - C) + D

To determine the specific values of A, B, C, and D that satisfy the given conditions, we can use the following steps:

Period: The period of a sinusoidal function is given by 2π/B, where B is the coefficient of x in the argument of the sine function. In this case, the period is 8, so we have:

2π/B = 8

Solving for B, we get:

B = π/4

Phase shift: The phase shift of a sinusoidal function is given by C/B, where C is the constant inside the argument of the sine function. In this case, the phase shift is -2, so we have:

C/B = -2

Substituting B from step 1, we get:

C/(π/4) = -2

Solving for C, we get:

C = -π/2

Amplitude and vertical shift: The range of the function is given as -12 ≤ y ≤ -4. The amplitude of a sinusoidal function is half the distance between its maximum and minimum values. In this case, the amplitude is:

(amplitude) = (maximum - minimum)/2 = (-4 - (-12))/2 = 4

The vertical shift of the function is given by the constant term D. Since the minimum value of the function is -12, we have:

D + (amplitude) = -12

Substituting the value of the amplitude from above, we get:

D + 4 = -12

Solving for D, we get:

D = -16

Therefore, the function of the form y = A sin(Bx - C) + D that has period 8, phase shift -2, and the range -12 ≤ y ≤ -4 is:

y = 4 sin(π/4 x + π/2) - 16

The graph of the equation x² + y - 36 = 0 is symmetric with respect to the y-axis and the origin, but not with respect to the x-axis.

x² + y - 36 = 0

Symmetry with respect to the x-axis:

Replace y with -y: x² - y - 36 = 0

This equation is not equivalent to the original equation, so the graph is not symmetric with respect to the x-axis.

Symmetry with respect to the y-axis:

Replace x with -x: (-x)² + y - 36 = 0

Simplifying, we get x² + y - 36 = 0, which is equivalent to the original equation.

Therefore, the graph is symmetric with respect to the y-axis.

Symmetry with respect to the origin:

Replace x with -x and y with -y: (-x)² + (-y) - 36 = 0

Simplifying, we get x² + y - 36 = 0, which is equivalent to the original equation.

Therefore, the graph is symmetric with respect to the origin.

Hence, the graph of the equation x² + y - 36 = 0 is symmetric with respect to the y-axis and the origin, but not with respect to the x-axis.

The function f(x) = 3x/(x-9) has a vertical asymptote at x=9, a horizontal asymptote at y=3 as x->±∞, and a horizontal asymptote at y=-3 as x->±∞.

To identify the asymptotes and state the end behavior of the function f(x) = 3x/(x-9), we need to analyze the behavior of the function as x approaches positive and negative infinity.

First, let's look at the denominator of the fraction, which is x-9. This means that the function has a vertical asymptote at x=9, as the denominator approaches zero at that point. This vertical asymptote divides the x-axis into two regions, x<9 and x>9.

Now let's consider the behavior of the function as x approaches positive infinity. In this case, the numerator grows faster than the denominator, and the function approaches a horizontal asymptote at y=3. To see this, we can use the limit definition:

lim (x->∞) f(x) = lim (x->∞) 3x/(x-9) = lim (x->∞) 3(1/(1-9/x)) = 3

Similarly, as x approaches negative infinity, the function also approaches a horizontal asymptote at y=-3. Again, we can use the limit definition to confirm this:

lim (x->-∞) f(x) = lim (x->-∞) 3x/(x-9) = lim (x->-∞) 3(1/(1-9/x)) = -3

Therefore, the function f(x) = 3x/(x-9) has a vertical asymptote at x=9, a horizontal asymptote at y=3 as x->±∞, and a horizontal asymptote at y=-3 as x->±∞.

Answer:

The length of the arc intercepted by a central angle of 3 radians in a circle of radius 76 is 228 and the length of the arc intercepted by a central angle of 2 radians in a circle of radius 15 is 30.

Explain:

The following formula determines the length of an arc that a circle's central angle intercepts:

Arc length is equal to (central angle / 2) 2r r r

where r denotes the circle's radius. We can determine the length of the two arcs using the following formula:

For the first circle, with a radius of 76 and a center angle of 3 radians:

Arc length = 3 x 76 = 228

Therefore, in a circle with a radius of 76, the length of the arc that is intercepted by a central angle of 3 radians is 228.

For the second circle, whose radius is 15, and whose center angle is 2 radians:

Arc length = 2 x 15 = 30

Answer: x^2 + 0x + 19/5 = 0

Step-by-step explanation: The initial step involves the equation -4x - 19 = x, which can be simplified by performing the operation of subtracting x from both sides.

The given equation can be represented as -5x - 19 = 0 in standard algebraic form, where 'x' denotes the unknown variable.

The process of combining similar or like terms leads to the consolidation of terms that share the same variable and corresponding exponents.

The given expression, 5x - 19 = 0, can be rewritten in an academic manner as a linear equation. Specifically, this expression represents a linear equation in one variable, where x is the unknown. The equation can be solved to find the value of x that satisfies it. This can be done through various methods, such as isolation of x, substitution, or using algebraic properties. The solution of this equation is x = 19/5, which can be verified by plugging it back into the original equation and observing its validity.

In order to render this equation in a standard format, it is imperative to eliminate the fixed element present on the left-hand side. The aforementioned task can be accomplished by simultaneously augmenting 19 to each side of the equation.

The equation 5x = 19 can be expressed in an academic manner as a linear equation with one variable. Specifically, it states that there is a value, x, that when multiplied by the constant factor of 5, results in a final product of 19. This equation could be used as a starting point for further mathematical analysis or application, such as solving for the specific value of x or incorporating it into a larger system of equations.

The left-hand side of the expression contains the linear term and the constant term, while the right-hand side is equal to 0. In order to express this equation in a standardized form, it is necessary to perform division by a factor of negative five to isolate the variable x.

The numerical value of the variable x is equivalent to negative nineteen divided by five, expressed as x = -19/5.

The standard form of the quadratic equation can be expressed as follows:

The mathematical expression, x + 19/5 = 0, may be restated in a formal academic style as follows: "The equation is of the form x + 19/5 = 0."

In order to determine the coefficients of the squared and constant terms, it can be observed that the coefficient of the squared term equates to 1 by virtue of the squared exponent of x, while the constant term evaluates to 19/5. This analytical approach yields the appropriate identification of the relevant coefficients in the given equation. Henceforth, the standard format for the quadratic equation is expressed as follows:

The equation in question is x^2 + 0x + 19/5 = 0.

PV = FV / (1 + r)ⁿ

where PV is the present value, FV is the future value, r is the discount rate, and n is the number of periods.

Using the given information, the FV is $48,000, the discount rate is 4%, 6%, or 8%, depending on the question, and the number of periods is three. Using a financial calculator, Excel, or present value tables, we can calculate the PV of the second payment:

For a discount rate of 4%:

PV = $48,000 / (1 + 0.04)³ = $41,306.64

For a discount rate of 6%:

PV = $48,000 / (1 + 0.06)³ = $38,249.94

For a discount rate of 8%:

PV = $48,000 / (1 + 0.08)³ = $35,693.44

Next, we need to add the PV of the second payment to the initial payment of $48,000 to get the total cost of the land today:

For a discount rate of 4%:

Total cost = $48,000 + $41,306.64 = $89,306.64

For a discount rate of 6%:

Total cost = $48,000 + $38,249.94 = $86,249.94

For a discount rate of 8%:

Total cost = $48,000 + $35,693.44 = $83,693.44
