The remaining balance after the lease ends, given the information would be B. $ 12,160.26.

The remaining balance after the lease ends can be found by the formula :

= Value of lease - Amount paid towards principal over 3 years - down payment

Amount paid towards principal over 3 years :

= ( 429. 95 x 70 % ) x 12 months x 3 years

= $ 10, 834. 74

The remaining balance is therefore :

= 23, 495 - 10, 834. 74 - 500

The values of x in the given equation, (x-7)^2=36, are x = 13 and x = 1. The correct options are the first and second options - x = 13 and x = 1

From the question, we are to determine the values of x in the given equation. The given equation is:

(x-7)^2=36

To solve the equation (x-7)^2=36, we can take the square root of both sides and solve for x:

The value of (g - f) (x) is -3x² + 2x - 4

The value of (f + g) (x) is 3x² + 6x - 6.

The value of (g / f) (x) is (4x - 5) / (3x² + 2x - 1).

The value of (fg) (x) is 12x³ - 7x² -14x + 5.

The solution has been obtained by using operations on functions.

What are operations on functions?

Similar to how we operate on the terms of the functions, we can add, subtract, multiply, and divide functions with overlapping domains using the operations on functions.

We are given f(x) = 3x² + 2x - 1 and g(x) = 4x - 5

(g - f) (x)

⇒(g - f) (x) = g(x) - f(x)

⇒(g - f) (x) = (4x - 5) - (3x² + 2x - 1)

⇒(g - f) (x) = 4x - 5 - 3x² - 2x + 1

⇒(g - f) (x) = 2x - 4 - 3x²

⇒(g - f) (x) = -3x² + 2x - 4

(f + g) (x)

⇒(f + g) (x) = f(x) + g(x)

⇒(f + g) (x) = (3x² + 2x - 1) + (4x - 5)

⇒(f + g) (x) = 3x² + 2x - 1 + 4x - 5

⇒(f + g) (x) = 3x² + 6x - 6

(g / f) (x)

⇒(g / f) (x) = g(x) / f(x)

⇒(g / f) (x) = (4x - 5) / (3x² + 2x - 1)

(fg) (x)

⇒(fg) (x) = f(x) * g(x)

⇒(fg) (x) = (3x² + 2x - 1) * (4x - 5)

⇒(fg) (x) = 12x³ - 7x² -14x + 5

Hence, the required solutions have been obtained.

A is invertible and its inverse is B = (-1/3)(A^3 + 2A - In). To show that A is invertible, we need to find a matrix B such that AB = BA = In, where In is the identity matrix of size

n × n.

First, let's rearrange the given equation:
A – 2A^2 -A^4 + 3In = 0
A^4 + 2A^2 - A + 3In = 0
Next, let's factor out A from the left side of the equation:
A(A^3 + 2A - In) = -3In

Now, let's multiply both sides of the equation by -1/3:
(-1/3)A(A^3 + 2A - In) = In

finally, let's set B = (-1/3)(A^3 + 2A - In):
AB = (-1/3)A(A^3 + 2A - In) = In
Therefore, the inverse of A is B = (-1/3)(A^3 + 2A - In).

To check our answer, we can multiply A and B to see if we get the identity matrix:

A coordinate system is a technique used to precisely find points or additional mathematical objects on a distance, such as Euclidean space, by using one or so more values or coordinates. To find a point or item on a double plane, one uses coordinates, which are pairs of numbers. Two numbers called the y and x matrices are used to describe a point's location on a two-dimensional plane. a set of numbers used to identify specific locations.

Here,

The x-coordinate remains constant and the y-coordinate is cancelled when a point on the coordinate plane is reflected over the x-axis (i.e. multiplied by -1). The y-coordinate remains constant and the x-coordinate is cancelled when a point is reflected over the y-axis.

Let's mirror the point (-2, 3) first over the x-axis and then over the y-axis as an illustration:

The x-coordinate remains constant while the y-coordinate is cancelled when reflecting over the x-axis. In light of this, the argument is (-2, -3).

The x-coordinate is cancelled while the y-coordinate remains constant when reflecting over the y-axis. In light of this, the argument is (2, -3).

The monthly payment on a 30-year, $100,000 mortgage with an interest rate of 6 percent is $599.55.

To find the monthly payment on a 30-year, $100,000 mortgage with an interest rate of 6 percent, we need to use the following formula:

Monthly Payment = (Loan Amount * Interest Rate) / (1 - (1 + Interest Rate)^(-Number of Payments))

First, we need to convert the interest rate from a percentage to a decimal by dividing it by 100:

Interest Rate = 6 / 100 = 0.06

Next, we need to calculate the number of payments over the life of the loan. Since there are 12 months in a year, and the loan is for 30 years, the number of payments is:

Number of Payments = 12 * 30 = 360

Now we can plug these values into the formula:

Monthly Payment = ($100,000 * 0.06) / (1 - (1 + 0.06)^(-360)) = $599.55

Therefore, A $100,000 mortgage with a 30 year term and a 6% interest rate has a $599.55 monthly payment.

To solve matrix equations using inverses, we need to use the inverse of the matrix M and multiply it by the matrix N to find the value of x.

First, we need to find the inverse of matrix M. We can do this by finding the determinant of M and then finding the adjoint of M.

The determinant of M is (7 * -8) - (5 * -5) = -56 + 25 = -31.

The adjoint of M is [[-8, 5], [-5, 7]].

To find the inverse of M, we need to divide the adjoint of M by the determinant of M:

M-1 = (1/-31) * [[-8, 5], [-5, 7]] = [[0.258, -0.161], [0.161, -0.226]].

Now, we can multiply the inverse of M by the matrix N to find the value of x:

Let's prove this using the coordinates of the three points A, B, and C that form triangle ABC. If we take line AB, it will intersect the triangle in the point P.

To prove that the only points of line AB that lie on the triangle are the points of the side AB, we must prove that point P is either point A or point B. We do this by showing that the coordinates of P are the same as the coordinates of either A or B.

The equation of line AB is given by y = mx + c, where m is the slope and c is the y-intercept. We can calculate m and c using the coordinates of points A and B:

m = (y2-y1)/(x2-x1)
c = y1 - m*x1

We can now calculate the coordinates of point P using the equation of line AB and the coordinates of point C:

x = (c - y3) / m
y = m*x + c

Finally, we can compare the coordinates of point P with the coordinates of points A and B. If the coordinates are the same, then point P is either point A or point B, and so line AB intersects the triangle ABC only in the points of side AB.

Let's say we have a line l that passes through points A(1, 2, 3) and B(4, 5, 6), and a point P(7, 8, 9) not on the line. We want to find a plane containing point P and parallel to line l.

Choose any point Q on the line l. Let's choose Q(1, 2, 3) for convenience.

Find the vector v that connects point Q to point P: v = P - Q = (7-1, 8-2, 9-3) = (6, 6, 6).

Find the direction vector d of the line l: d = (4-1, 5-2, 6-3) = (3, 3, 3).

Take the cross product of the direction vector d and the vector v: d x v = <3, 3, 3> x <6, 6, 6> = <0, 18, -18>.

Write the equation of the plane: 0x + 18y - 18z = d. Since the plane is parallel to line l, we know that the coefficients of x, y, and z are all 0, except for the coefficients of y and z, which are the components of the vector d x v. Therefore, the equation simplifies to 18y - 18z = 0, or y - z = 0.

So the plane containing point P(7, 8, 9) and parallel to the line passing through points A(1, 2, 3) and B(4, 5, 6) can be represented by the equation y - z = 0.
