Answer:

The answer is in the picture below, i didn't know how to put it in words sorry.

Step-by-step explanation:

The rule for the transformation above include the following: B. (x' , y') = (x - 6 , -y + 1).

In Geometry, a reflection over the x-axis is given by this transformation rule (x, y) → (x, -y). This ultimately implies that, a reflection over the x-axis would maintain the same x-coordinate while the sign of the x-coordinate changes from positive to negative or negative to positive:

(x, y)                               →              (x, -y)

This ultimately implies that, the parallelogram was reflected over the x-axis and then translated by 6 units to the left, and followed by a vertical translation downward by 1 unit.

(x' , y') = (x - 6 , -y + 1)

(x' , y') = (1 - 6 , -2 + 1)

(x' , y') = (-5, -1)

(a) To find the product of -2x^3+x and x^3-3x-4, we can use the distributive property of multiplication:

(-2x^3 + x)(x^3 - 3x - 4)

= -2x^3(x^3) - 2x^3(-3x) - 2x^3(4) + x(x^3) - x(-3x) - x(4)

= -2x^6 + 6x^4 - x

= -2x^6 + 6x^4 - x

Therefore, the product of -2x^3+x and x^3-3x-4 is -2x^6 + 6x^4 - x.

(b) No, the product of 2x^3+x-5 and x^3-3x-4 is not equal to the product of x^3-3x-4 and -2x^3+x-5. This is because the order of the factors in a multiplication expression affects the outcome. When we expand both products using the distributive property, we get different expressions:

(2x^3 + x - 5)(x^3 - 3x - 4) = 2x^6 - 5x^3 - 3x^2 - 17x + 20

(x^3 - 3x - 4)(-2x^3 + x - 5) = -2x^6 + 11x^4 + 13x^3 - 3x^2 - x + 20

So the expanded expressions are not equal. Therefore, the two products are not equal.

When x^3+2x^2+x+1 is divided by (x+1) then remainder is 1.

In the given question, we have to find what is remainder when x^3+2x^2+x+1 is divided by (x+1).

To find the remainder there are two ways. First we divide the x^3+2x^2+x+1 by (x+1). Second we find the value of from (x+1) by equating (x+1) equal to zero. The put the value of x in the expression x^3+2x^2+x+1.

In this we ca easily find the remainder.

Now we firstly find the value of x;

(x+1) = 0

Subtract 1 on both side we get;

x= −1

Now put x= -1 in the expression x^3+2x^2+x+1.

x^3+2x^2+x+1 = (−1)^3+2(−1)^2+(−1)+1

x^3+2x^2+x+1 = −1+2−1+1

x^3+2x^2+x+1 = 1

Hence, when x^3+2x^2+x+1 is divided by (x+1) then remainder is 1.

On the assumption that each curve has only real roots, the quartic function is the graph C.

In this question we have four choices of graphs of polynomials, that is algebraic expressions of the form:

p(x) = Σ cₙ · xⁿ, for n = {0, 1, 2, 3, ..., m - 1, m}

Where m is the grade of the polynomial.

The factor form of the polynomial is described below:

p(x) = a · Π (x - rₙ), for n = {0, 1, 2, 3, ..., m - 1, m}

If we consider that each choice has real roots, then the grade of the polynomial coincides with the number of times that the curve pass through the x-axis. Then, the graph C represent a quartic function, that is, a polynomial with grade 4 with the special feature that is a function of the form f(x) = a · x² · (x - r₁) · (x - r₂).

This means that the average cost of selected automobiles has increased by 16% between the two years.

Given data: The average cost of selected automobiles in 2019 = $15,000

The average cost of selected automobiles now (current year) = $17,400

Let's calculate the rate of increase in the average cost of the automobile between the two years.

To find the rate of increase, use the following formula;
rate of increase = increase in value / original value * 100

To get the increase in the value of selected automobiles, subtract the current year's average cost of selected automobiles from the previous year's average cost of selected automobiles.

i.e. increase in value = current year's average cost - previous year's average cost

= $17,400 - $15,000

= $2,400

Now put the values in the formula to get the rate of increase;

rate of increase = increase in value / original value * 100

= 2400 / 15000 * 100

= 16

Therefore, the rate of increase for selected automobiles between the two time periods is 16%.

It's essential to note the rate of increase or decrease in the value of products or services. It helps in decision making, future predictions, etc.

The above question deals with finding the rate of increase in the cost of selected automobiles. To get the rate of increase, the formula rate of increase = increase in value / original value * 100 is used.

To get the increase in the value of selected automobiles, subtract the current year's average cost of selected automobiles from the previous year's average cost of selected automobiles. i.e. increase in value = current year's average cost - previous year's average cost.

The value of selected automobiles was $15,000 in 2019, and now it is $17,400.

Now, the rate of increase in the average cost of automobiles can be found using the formula rate of increase = increase in value / original value * 100.

Put the values in the formula to get the rate of increase.

Therefore, the rate of increase for selected automobiles between the two time periods is 16%.

It indicates that if a person had bought an automobile in 2019 for $15,000, he has to pay $17,400 for the same automobile now.

If the area is 384 square feet, then the length of the altitude is 36 feet, and the length of the base is 44 feet.

Let's start by using the formula for the area of a triangle in terms of its base and altitude:

\(Area = (1/2) * base * altitude\)

We know that the area of the triangle is 384 square feet:

\(384 = (1/2) * base * altitude\)

Next, we're given that the base is 8 feet longer than the altitude:

\(base = altitude + 8\)

We can substitute this expression for the base into the area formula:

\(384 = (1/2) * (altitude + 8) * altitude\)

Simplifying and multiplying out the right-hand side:

\(384 = (1/2) * (altitude^2 + 8altitude)\\768 = altitude^2 + 8altitude\)

Now we have a quadratic equation in terms of the altitude. We can solve for the altitude by first rearranging the equation:

\(altitude^2 + 8altitude - 768 = 0\)

Then, we can solve for the altitude using the quadratic formula:

\(altitude = (-8 ± sqrt(8^2 - 4(1)(-768))) / (2(1))\\altitude = (-8 ± sqrt(6400)) / 2\\altitude = (-8 ± 80) / 2\)

We get two possible values for the altitude:

altitude = -44 or altitude = 36

Since the altitude of a triangle must be positive, we discard the negative solution and choose altitude = 36 feet.

We can then use the expression for the base in terms of the altitude to find the length of the base:

\(base = altitude + 8 = 36 + 8 = 44 feet\)

Therefore, the length of the altitude is 36 feet and the length of the base is 44 feet.

The smaller circle's area is about 31% of the larger circle's area.

To find the ratio of the smaller circle's area to the larger circle's area, we need to know the radius of each circle. From the given code, we know that the larger circle has a radius of 1 because the square root of 0.97 is approximately 0.985, which is less than 1. Therefore, the larger circle's area is pi times the square of 1, which simplifies to just pi.

To find the radius of the smaller circle, we need to remember that the area of a circle is proportional to the square of its radius. Since the ratio of the smaller circle's area to the larger circle's area is equivalent to the ratio of their radii squared, we can set up the following proportion:

(smaller radius)^2 : 1^2 = 0.97 : 1

Simplifying this, we get:

(smaller radius)^2 = 0.97

Taking the square root of both sides, we get:

smaller radius = sqrt(0.97)

Therefore, the smaller circle's area is pi times the square of sqrt(0.97). Simplifying this, we get:

smaller circle's area = pi * 0.97

So, the ratio of the smaller circle's area to the larger circle's area is:

0.97 : pi

or approximately:

0.309 : 1

Therefore, the smaller circle's area is about 31% of the larger circle's area.

The expression for the power delivered to a resistance in terms of csc^2 2 pi ft is P = I^2_0 R (csc^2 2 pi ft).

According to the given information, the power delivered to a resistance R when an alternating current of frequency f and peak current I_0 passes through it is represented by the equation P = I^2_0 R sin^2 2 pi ft.

To express this equation in terms of csc^2 2 pi ft, we can use the trigonometric identity csc^2 x = 1/sin^2 x. Substituting this identity into the equation, we get P = I^2_0 R (1/sin^2 2 pi ft).

Since csc^2 x is the reciprocal of sin^2 x, we can rewrite the equation as P = I^2_0 R (csc^2 2 pi ft). This expression represents the power delivered to the resistance in terms of csc^2 2 pi ft.

Therefore, the correct expression for the power delivered to the resistance in terms of csc^2 2 pi ft is P = I^2_0 R (csc^2 2 pi ft).

There are 48 valid strings of length 5 that we can create using the letters X, Y, and Z.

First, let's consider how many strings of length 1 we can create. We have three choices for the first letter - X, Y, or Z - so there are 3 possible strings of length 1.

Next, let's consider how many strings of length 2 we can create. We cannot use the same letter twice in a row, so for the second letter, we only have two choices.

Therefore, there are 2 possible strings of length 2 for each of the 3 possible strings of length 1, giving us a total of 6 possible strings of length 2.

Moving on to strings of length 3, we now have to consider the choices for the third letter. Again, we cannot use the same letter twice in a row, so for the third letter, we also have two choices. Therefore, there are 2 possible strings of length 3 for each of the 6 possible strings of length 2, giving us a total of 12 possible strings of length 3.
