The exchange rate for 15 American Dollars is 17.1 Euro. And 7 Euro are worth 435.2 Dominican Pesos. How
much is 12 American dollars worth in Dominican Pesos?

Answers

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.

Determine whether the graph of the equation is symmetric with respect to the x axis, y axis and or the origin.
X^2 + Y -36 =0

Answers

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.

Write the quadratic equation in standard form:-4x – 19 = x

Answers

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.

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

Answers

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

Answers

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->±∞.

Answers

To find the percentage invested in bonds, we need to add the amounts invested in U.S. Treasuries and high-grade corporate bonds, and then divide by the total value of the portfolio:

Total amount invested in bonds = $45,000 + $32,000 = $77,000

Total portfolio value = $45,000 + $32,000 + $74,000 = $151,000

Percentage invested in bonds = (Total amount invested in bonds / Total portfolio value) x 100%

Find the line parallel to y = -9x-1 that includes the point (2, -3). y- [?] = [?] ( x - [?])​

Answers

Answer:

y + 3 = - 9(x - 2)

Step-by-step explanation:

the equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

y = - 9x - 1 ← is in slope- intercept form

with slope m = - 9

• Parallel lines have equal slopes

then slope of parallel line is m = - 9

the equation of a line in point- slope form is

y - b = m(x - a)

where m is the slope and (a, b ) a point on the line

m = - 9 and (a, b ) = (2, - 3 ) , then

y - (- 3) = - 9(x - 2) , that is

y + 3 = - 9(x - 2)

An appropriate assignment of digits to the outcomes for a simulation of this random process would be:

Option 1: Let 0 and 1 = the student is enrolled in the nursing program. Let 2-5 = the student is not enrolled in the nursing program. Skip the digits 6, 7, 8, 9, and 0.

This option assigns two digits, 0 and 1, to represent the two possible outcomes: a student is either enrolled in the nursing program (outcome 1) or not enrolled (outcome 2-5). The digits 2-5 represent the non-nursing program outcomes, and the digits 6-9 and 0 are skipped.

Option 1 is appropriate because it assigns a unique digit to each possible outcome, and the skipped digits are not relevant to the simulation. Additionally, the proportion of digits assigned to each outcome (2 out of 10) corresponds to the proportion of students in the nursing program (20%).

Answers

According to the compound interest concept the total cost of the land today is $89,306.64, $86,249.94, $83,693.44 respective to the discount percentage.

To calculate the PV of the second payment of $48,000 due in three years, we need to use the formula for the present value of a single sum:

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

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

As a result, the length of the arc in a circle with a radius of 15 is 30 when it is intercepted by a central angle of 2 radians.

A company's survey of 150 employees find that on average an employee drinks 10.2 cups of coffee during the workweek with a margin of error of #0.6. Using this data, it is estimated that a maximum of 6, 048 cups of coffee will be consumed during a workweek. What is the total number of employees in the company?
• 403
• 560
• 593
• 630

Answers

The total number of employees in the company is 560.

What is total number of employees?

The total number of employees in the company is calculated as follows;

the true average number of cups of coffee consumed per employee during the workweek is 10.2 ± 0.6 cups.

maximum = 10.8 cups/employee

minimum = 9.6 cups/employee

The minimum number of employees is calculated as;

n_m = 6,048 cups / 10.8

n_m = 560

The maximum number is calculated as;

n_max = 6,048 cups/9.6

n_max = 630

Based on the error margin, we take the minimum number.

A ladder is leaning against a house at a 50 degree angle. If the ladder is 80 feet long, how high up is it from the ground at the top of the ladder?
We are missing a side or and angle?
Regular or Inverse Trig?

Answers

The height from the ground to the top of the ladder is 61. 28 feet

How to determine the height

First, we need to know that their are six different trigonometric identities.

These identities includes;

secantcotangenttangentcosinesinecosecant

From the information given, we have that;

the height of the ladder that is leaning against the house = 80 feet

This the hypotenuse side

The angle of elevation is 50 degrees

Then, the opposite side is the height from the ladder = x

Using the sine identity, we have;

sin 50 = x/80

cross multiply the values

x = 61. 28 feet

Mrs. Myles gave the same test to both her first and third period class. In first period, the median was 75 and the range was 30. In third period, the median was 80 and the range was 60. Which is a true statement? [Assume that scores can reach a maximum of 100.]
A The lowest score was in third period.The lowest score was in third period. - no response given
B On average, first period did better than third period.On average, first period did better than third period. - no response given
C The highest score was in first period.The highest score was in first period. - no response given
D There is not enough information to know if any of these is true.

Answers

Answer:

D There is not enough information to know if any of these is true.

Based purely on the facts provided, we cannot draw any judgements regarding the relative performance of the two classes. The range and median are important indices of central tendency and dispersion, but they do not offer an accurate picture of the score distribution. We don't know the distribution's form, the number of students in each class, or each student's exact score. As a result, we can't tell whether class received the lowest or highest score, or whether one class performed better overall than the other.

The table below show the data to find an exponential model.


x 1 4 7 8 10

y. 798 1078 1519 2075 3102

1 goes with 798, 4 goes with 1078, 7 goes with 1519, 8 goes with 2075, and 10 goes with 3102

a. Write the data set to be used in order to linearize the data.


b. Write the system of equations


c. Write the matrices.


d. Indicate the c values


e. Write the exponential model in the form Y=C* 10^bx

Answers

a. The exponential model is of the form Y=Ce^bx. Taking natural logarithms of both sides of the equation, we get ln(Y)=ln(C)+bx. This form is linear in ln(Y).

The data set to be used to linearize the data is:

x ln(y)
1 ln(798)
4 ln(1078)
7 ln(1519)
8 ln(2075)
10 ln(3102)

b. The system of equations is:

$\begin{pmatrix}5 & \sum_{i=1}^{5} x_i \\ \sum_{i=1}^{5} x_i & \sum_{i=1}^{5} x_i^2 \\\end{pmatrix}\begin{pmatrix}b \\ ln(C) \\\end{pmatrix}=\begin{pmatrix}\sum_{i=1}^{5} ln(y_i) \\ \sum_{i=1}^{5} x_i ln(y_i) \\\end{pmatrix}$

c. The matrices are:

$\begin{pmatrix}5 & \sum_{i=1}^{5} x_i \\ \sum_{i=1}^{5} x_i & \sum_{i=1}^{5} x_i^2 \\\end{pmatrix}\begin{pmatrix}b \\ ln(C) \\\end{pmatrix}=\begin{pmatrix}\sum_{i=1}^{5} ln(y_i) \\ \sum_{i=1}^{5} x_i ln(y_i) \\\end{pmatrix}$

$\begin{pmatrix}5 & 30 \\ 30 & 266 \\\end{pmatrix}\begin{pmatrix}b \\ ln(C) \\\end{pmatrix}=\begin{pmatrix}7.986 \\ 27.214 \\\end{pmatrix}$

d. Solving for b and ln(C) using a calculator or a matrix-solving tool, we get:

b = 0.2695
ln(C) = 6.6195

Taking exponential of ln(C) we get C = 760.9305.

Therefore, the values of c are: C = 760.9305.

e. The exponential model in the form Y=C * 10^(bx) is:

Y = 760.9305 * 10^(0.2695x).
