Answer:

A. 18x - 3y = 6

Step-by-step explanation:

By taking 3 common from the terms 18x and 3y we get,

3 (6x-3y) = 6

or, 6x - y = 6/3

or, 6x - y = 2

And,

The equation becomes,

y = 6x - 2

The equation has exactly one solution in common with the equation y=6x-2 will be 18x - 3y = 6. The correct option is A.

A finite set of equations for which common solutions are sought is referred to in mathematics as a set of simultaneous equations, often known as a system of equations or an equation system.

An equation is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.

By taking 3 commons from the terms 18x and 3y we get,

3 (6x-3y) = 6

6x - y = 6/3

6x - y = 2

The equation becomes,

y = 6x - 2

Therefore, the equation has exactly one solution in common with the equation y=6x-2 will be 18x - 3y = 6. The correct option is A.

The maximum price Matthew can pay for the car, considering his repayment capability and the loan terms, is approximately $126,318.29.

To determine the maximum price Matthew can pay for the car, we need to consider his repayment capability and the terms of the loan.

Matthew can make annual repayments of $35,000. Since the loan term is six years, the total amount he can repay over the loan period is $35,000 multiplied by six, which equals $210,000.

To calculate the maximum price of the car, we need to account for the interest rate of 9.25%. The interest rate represents the cost of borrowing and is applied to the loan amount.

Let's assume the loan amount is denoted by P.

The formula to calculate the future value of a loan with interest is:

FV = P(1 + r)^n

Where:

FV = Future value (total amount repaid)

P = Principal amount (maximum price of the car)

r = Interest rate per period (9.25% or 0.0925)

n = Number of periods (six years)

Since Matthew can repay a total of $210,000 over the loan period, we can set up the equation:

$210,000 = P(1 + 0.0925)^6

Now we can solve for P:

P = $210,000 / (1 + 0.0925)^6

Evaluating this expression, we find:

P ≈ $126,318.29

Therefore, the maximum price Matthew can pay for the car, considering his repayment capability and the loan terms, is approximately $126,318.29.

Answer:

38°.

Step-by-step explanation:

A triangle adds up to 180°.

CAB= 78°

But we minus 78° from 46°:

32°.

As a triangle adds up to 180°,

110+32= 142°.

180-142= 38°.

To see if we are correct:

38+32+110= 180°.

To determine which values of a and b make the given linear differential equation homogeneous, we need to check if the equation satisfies the condition for homogeneity.

A linear differential equation of the form Y = x^b * y' = F(x, y) is homogeneous if and only if F(tx, ty) = t^a * F(x, y), where t is a constant.

Substituting the given equation into the homogeneity condition, we have:

(x^b)(tx)^2 * (ty) + (tx)(ty)^2 / (tx + (ty)^2) = t^a * ((x^b)(y) + (x)(y^2) / (x + (y)^2))

Simplifying the equation, we get:

t^(2+b) * x^(2+b) * t * y + t^(1+b) * x * t^2 * y^2 / (t * x + t^2 * y^2) = t^a * (x^b * y + x * y^2 / (x + y^2))

Now, we compare the powers of t and x on both sides of the equation.

From the terms involving t, we have 2+b = a and 1+b = a.

From the terms involving x, we have 2+b = b and 1 = b.

Solving these equations, we find that the only values of a and b that satisfy the conditions are:

a = 1 and b = 0.

Therefore, the correct choice is II. a = 1 and b = 0.

Step-by-step explanation:

The area of quadrilateral AMNO is approximately 2.4 square inches.

To find the area of quadrilateral AMNO, we can use the formula for the area of a general quadrilateral, which states that the area can be calculated as half the product of the diagonals multiplied by the sine of the angle between them. In this case, the diagonals are AM and NO, and the angle between them is ZO.

Given that m = 1.3 inches and n = 2.1 inches, we can use these values to calculate the area.

First, we need to find the length of the diagonals AM and NO. Using the Pythagorean theorem, we can find the length of AM:

AM = √(AO^2 + OM^2)

= √(m^2 + n^2)

= √(1.3^2 + 2.1^2)

≈ √(1.69 + 4.41)

≈ √6.1

≈ 2.47 inches

Similarly, the length of NO is also 2.47 inches.

Now, we can calculate the area of AMNO using the formula:

Area = (1/2) * AM * NO * sin(ZO)

Plugging in the values, we have:

Area = (1/2) * 2.47 * 2.47 * sin(138°)

Using a calculator, we find that sin(138°) ≈ 0.9401.

Substituting the values, we get:

Area ≈ (1/2) * 2.47 * 2.47 * 0.9401

≈ 2.4267 square inches

The Laplacian operator Δu of a twice differentiable function u on R^N, where N is the number of dimensions, can be expressed in spherical coordinates as Δu = u_rr + (r^(N-1))(u_r), where u_rr represents the second derivative of u with respect to r, u_r represents the first derivative of u with respect to r, and r is the radial distance from the origin.

To show this result, we start by expressing the partial derivative of u with respect to x_j in terms of spherical coordinates. In spherical coordinates, x_j can be written as r*x_j, where r is the radial distance and x_j is the unit vector in the j-th direction. Therefore, we have:

∂u/∂x_j = (∂u/∂r)(∂r/∂x_j) = (∂u/∂r)*x_j.

Next, we differentiate both sides of this equation with respect to x_j:

∂x_j(∂u/∂x_j) = (∂x_j(∂u/∂r))*x_j = (∂(∂u/∂r)/∂x_j)*x_j.

Now, we can evaluate the partial derivative of (∂u/∂r) with respect to x_j. Since u depends only on r, the derivative of (∂u/∂r) with respect to x_j is zero, giving us:

∂x_j(∂u/∂x_j) = (∂(∂u/∂r)/∂x_j)*x_j = 0*x_j = 0.

Therefore, we have shown that ∂x_j(∂u/∂x_j) = 0.

AC = 10, therefore CD = 18 - 10 = 8.

Answer: Yes, because his calculation should be 150% of 330.

Step-by-step explanation:

150×330 = 495

148% of 333 is 495 is not true because 148% of 333 is 493.

The percentage is calculated by dividing the required value by the total value and multiplying by 100.

Example:

Required percentage value = a

total value = b

Percentage = a/b x 100

Example:

50% = 50/100 = 1/2

25% = 25/100 = 1/4

20% = 20/100 = 1/5

10% = 10/100 = 1/10

We have,

148% of 333

This can be written as,

148/100 x 333

A value hypothesis explains the reasons why a customer may choose not to use a product: false.

In Mathematics, a value hypothesis can be defined as a type of hypothesis which test whether or not a product or service really delivers value to customers once it is being used by them.

This ultimately implies that, a value hypothesis proposes a handful of assumptions about a product or service while structuring them, so as to be verified or rejected.

In this context, we can reasonably infer and logically deduce that a value hypothesis does not explain the reason why a product is rejected and not used by a customer.

Answer : tanθ = sqrt(1 - (910)²) / 910

Given:  that the terminal side of angle θ intersects the unit circle in the first quadrant at (910, y), we can find the value of tanθ using the coordinates.

Explanation:
   Recall that on the unit circle, tanθ = y/x. In this case, x = 910 and y is the unknown value. However, since we are in               the first quadrant, both x and y will be positive.

To find y, we can use the Pythagorean theorem for the unit circle: x² + y² = 1.

Substitute x = 910:
(910)² + y² = 1
y² = 1 - (910)²

Now, since y is positive in the first quadrant, we take the positive square root:
y = sqrt(1 - (910)²)

Finally, find tanθ = y/x:
tanθ = sqrt(1 - (910)²) / 910

The required function is d = 90t and  cheetah will travel 2250 feet in 25 seconds.

That is Speed = distance*time. Alternatively, you can calculate the duration by dividing the distance traveled by the speed. You can figure out the third input if you know two of the inputs. For instance, if a car goes 120 miles in 2 hours, we can calculate the speed as 120 x 2 = 60 miles per hour.

The distance d traveled by the cheetah is given by the formula:

d = rt

where r is the rate (speed) of the cheetah and t is the time (in seconds) traveled.

Substituting the given values, we get:

d = 90t

Therefore, the function that relates the distance traveled by the cheetah to the time traveled is:

d(t) = 90t

To find how far the cheetah will travel in 25 seconds, we can simply substitute t = 25 into the function:

d(25) = 90(25) = 2250 ft.

Therefore, the cheetah will travel 2250 feet in 25 seconds.

A.The probability of a response from the agency in 3 days or less =P(X ≤ 3) = e^(-4)*(1/0! + 4/1! + 4^2/2! + 4^3/3!)

B.The probability that the agency response takes more than 10 but less than 13 days=P(10 < X < 13) = P(X = 11) + P(X = 12).

C,The probability that the agency response takes more than 5 days=P(X > 5) = 1 - (P(X ≤ 0) + P(X ≤ 1) + P(X ≤ 2) + P(X ≤ 3) + P(X ≤ 4) + P(X ≤ 5)),

D.the expected value of the new variable "Responsive,"=E(Responsive) = 1 * P(X ≤ 5) + 0 * P(X > 5)

a. The probability of a response from the agency in 3 days or less can be calculated by summing the individual probabilities for X = 0, 1, 2, and 3:

P(X ≤ 3) = f(0) + f(1) + f(2) + f(3)

Plugging in the given PMF, we have:

P(X ≤ 3) = e^(-4)*(1/0! + 4/1! + 4^2/2! + 4^3/3!)

b. The probability that the agency response takes more than 10 but less than 13 days can be calculated by subtracting the cumulative probability for X = 10 from the cumulative probability for X = 13:

P(10 < X < 13) = P(X = 11) + P(X = 12)

Using the given PMF, we can calculate the probabilities for X = 11 and X = 12 and sum them up.

c. The probability that the agency response takes more than 5 days can be calculated by subtracting the cumulative probability for X = 0, 1, 2, 3, 4, and 5 from 1 (since it's the complement event):

P(X > 5) = 1 - (P(X ≤ 0) + P(X ≤ 1) + P(X ≤ 2) + P(X ≤ 3) + P(X ≤ 4) + P(X ≤ 5))

d. To find the expected value of the new variable "Responsive," we can multiply the values of the variable (1 or 0) by their respective probabilities and sum them up:

E(Responsive) = 1 * P(X ≤ 5) + 0 * P(X > 5)

e. To find the variance of "Responsive," we can use the formula:

Var(Responsive) = E(Responsive^2) - (E(Responsive))^2

where E(Responsive^2) is the expected value of the square of the variable "Responsive." We can calculate it by multiplying the squared values (1 or 0) by their respective probabilities and summing them up.

The percent yield is calculated as the ratio of the actual yield to the theoretical yield, multiplied by 100.

Percent yield is a measure of how efficient a chemical reaction or process is in producing the desired product.

The formula for percent yield is:

Percent Yield = (Actual Yield / Theoretical Yield) * 100

The actual yield is the amount of product obtained from the reaction or process, typically measured in grams or moles. It represents the actual amount of product obtained in the laboratory.

The theoretical yield, on the other hand, is the maximum amount of product that can be obtained based on stoichiometry and other factors. It is calculated using balanced chemical equations and the starting amounts of reactants.

By dividing the actual yield by the theoretical yield and multiplying by 100, we get the percent yield, which is expressed as a percentage.

This value provides insight into the efficiency of the reaction or process, with a higher percent yield indicating a more efficient conversion of reactants into products.
