Answer:

y = -1/35x + 71/35

Step-by-step explanation:

slope of the perpendicular line = -1/35  (the negative reciprocal of 35)

use the point (1,2) and the point-slope form:

y - 2 = -1/35(x - 1)  now put it in slope-intercept form

y = -1/35x + 1/35 + 2

y = -1/35x + 71/35

0r,  y = -1/35(x - 71)

The equation of the line perpendicular to y = 35x − 4 and passing through the point (1, 2) is y = (-1/35)x + 71/35.

To find the equation of the line perpendicular to y = 35x − 4 and passing through the point (1, 2), we need to follow these steps:

y - 2 = (-1/35)(x - 1)

y - 2 = (-1/35)x + 1/35
y = (-1/35)x + 1/35 + 2
y = (-1/35)x + 71/35

So, the equation of the line perpendicular to y = 35x − 4 and passing through the point (1, 2) is y = (-1/35)x + 71/35.

Answer: 6

Step-by-step explanation:

Let's start with what we know. We have the following equation:

x^2 + 7 = 43

Now, we subtract 7 from both sides.

x^2 = 36

Then we take the square root of both sides giving our final answer:

x = 6.

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:

(x-7)^2 = 36

Taking the square root of both sides:

x - 7 = ±6

Adding 7 to both sides:

x = 7 ± 6

So we get two possible values of x:

x = 7 + 6 or x = 7 - 6

x = 13 or x = 1

Hence, the correct values of x are:

x = 13

x = 1

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.

Therefore, for the first  coordinate point (-x, y), the ultimate reflected points are (-x, -y) and (-x, -y), and for the second point, they are (x, -y) and (-x, -y) .

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.

We can use the Pythagorean theorem to find the hypotenuse of the right triangle formed by the given point (4, 3) and the origin (0, 0):

r = √(4² + 3²) = 5

Then we can use the coordinates of the point (4, 3) to determine the values of the trigonometric functions:

sin(θ) = opposite/hypotenuse = 3/5

cos(θ) = adjacent/hypotenuse = 4/5

tan(θ) = opposite/adjacent = 3/4

To find a plane containing a point P not on a given line l and parallel to l, we can follow these steps:

Choose any point Q on the line l.

Find the vector v that connects point Q to point P, i.e., v = P - Q.

Find the direction vector d of the line l.

Take the cross product of the direction vector d and the vector v, denoted by d x v.

The plane that contains point P and is parallel to line l can be represented by the equation ax + by + cz = d, where (a, b, c) is the vector d x v, and x, y, and z are the coordinates of any point on the plane.

Here's an example to illustrate the process:

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.

Zachary will need to earn a score of 23 on his sixth quiz to have a mean score of 22 for all six quizzes.

To find out what score Zachary needs to earn on his sixth quiz to have a mean score of 22,

We need to use the formula for the mean (or average) of a set of numbers:

Mean = (sum of all the scores) / (number of tests)

Zachary's mean score for the first five quizzes is 22.

Using the above as a guide, we have the following:

(20 + 25 + 22 + 18 + 24 + x) / 6 = 22

Evaluate the like terms

(109 + x) / 6 = 22

So, we have

109 + x = 132

Evaluate the like terms

x = 23

Hence, the score must be 23
