Answer:

It is clear that the annual premium = $1080

Explanation:

Given:

As the total term amount for life insurance is given in the question which is $200,000

rate per $1000 unit = $5.40

Simple Calculation Procedure to get the annual premium:

First step:  

Let’s assume $1000 is one unit and the mentioned rate per $1000 unit is $5.40. Now, all you need is to find total number of $1000 units in total term insurance amount ($200,000).  

So,  

divide $200,000 by $1000 to establish the total number of  

1000 units in $200,000 = $200,000/$1000 = 200  

Second step:

As 200 is found to be the total number of $1000 units in $200,000.

So, just multiply 200 with $5.40 to ultimately find the annual premium

            i.e. $5.40 × 200 = $1080

Hence, it is clear that the annual premium = $1080

Answer:

Only option D is correct as a dilation by a scale factor of 1/2 with the origin as the center of dilation would transform the object which would still be similar to the original figure, but it would no longer be congruent to the original figure due to reduction in size due to a dilation by a scale factor of 1/2.

Step-by-step explanation:

When we transform a certain shape, we normally associate the original shape as 'object', while the transformed shape is associated as "image',

If any shape like triangle, parallelogram or any other certain quadrilateral is rotated, reflected or translated, it wold preserve the same size. Hence, the resulting transformed image would be similar and also called 'congruent' to the original object.

But, if any shape like triangle, parallelogram or any other certain quadrilateral is enlarged or resized, it would certainly change in size. Therefore, the resulting transformed image would still be considered as similar, but it would no longer congruent to the original object.

Hence, when two transformation are performed on a figure in the coordinates plane. The first transformation is a translation 8 units to the left. A dilation by a scale factor of 1/2 with the origin as the center of dilation would transform the object which would still be similar to the original figure, but it would no longer be congruent to the original figure due to reduction in size due to a dilation by a scale factor of 1/2.

In all other cases, like a clockwise rotation of 90 degrees about the center, A clockwise rotation of 180 degrees about the center and a dilation by a scale factor of 1 with the origin as the center of a dilation would not not alter the size of the shape, and the resulting transformed image would be similar as well as called 'congruent' to the original object.

Hence, only option D is correct as a dilation by a scale factor of 1/2 with the origin as the center of dilation would transform the object which would still be similar to the original figure, but it would no longer be congruent to the original figure due to reduction in size due to a dilation by a scale factor of 1/2.

Therefore, only option D is correct.

The Sedona transformation that will result in an image that is similar to, but not congruent to the original figure is D. A dilation by a scale factor of 1/2 with the origin as the center of dilation.

To get an image that is similar but not congruent to the original figure, we shall perform a transformation that changes the size of the figure while keeping the same shape.

This is because when a figure is translated 8 units to the left, its position changes, but its size and shape remain the same.

A dilation by a scale factor of 1/2 with the origin as the center of dilation means the image would be reduced to half of its original size while maintaining the same shape.

This transformation results in a figure that is similar but not congruent to the original figure, as it has the same shape but a different size.

Answer:

a) x=-10,0,11

b) x<-10, 0<x<11

c) x>11, -10<x<0

Step-by-step explanation:

a) Find all the intersecting points of the two graphs.

b) Find all the x values when g(x) (the curving one) is higher than f(x). g(x) or f(x) is kind of like the y coordinate in these graphs. There for to find when f(x)<g(x), you have to find when g(x) is above f(x). Any part of g(x) above the intersecting points is your answer. So we can see that at -10, the curving line is above the straight one, f(x). There for that would be when x<-10, g(x)>f(x). Use these intersection points to figure out the rest.

c) Find all the x values of when the curving line, g(x) is below f(x), the straight line. Use the points where the two lines intersect t start off your answer. For example, we can see the curved line is below the straight one between -10 and 0. Therefore, f(x)>(g) when -10<x<0. x>11 is the only other moment when g(x), the curving line is also below f(x).

Final answer:

20% does not directly convert into a whole number; it represents a fractional part of a whole. If you look at the percent as a part of some quantity, you calculate 20% of that quantity to find the represented part. However, 20% by itself is 0.20 in decimal form, not a whole number.

Explanation:

What is 20% as a whole number?

When talking about percentages, it's important to understand that a percent is a way of expressing a fractional amount as part of a whole divided into 100 parts. For example, 5% means 5 out of 100.

In the case of 20%, you are looking at 20 out of 100. As a whole number, however, percentages less than 100% do not directly convert since they represent a part of a whole, not the whole itself. 20% can be represented as 0.20 in decimal form, which still does not constitute a whole number. The closest concept related to whole numbers would be if you had some quantity that you wish to find 20% of; you would then calculate 20% of that number to find the part it represents. But the 20% by itself remains a fraction, not a whole number.

Answer:

16y² - x² shows a correct difference of squares.

Step-by-step explanation:

Following are the given options from which we have to chose which represents the difference of squares.

A) 10y² - 4x²

B) 16y² - x²

C) 8x² - 40x+25

D) 64x² - 48x+9

Difference of square is given by:

a² - b² = (a + b) (a - b)

If we analyze the expressions from the choices given in the question. We should figure out that option B) should be the right answer that shows a difference of squares. i.e. 16y² - x² shows a correct difference of squares. All other options do not represent the difference of perfect squares.

As in option A) 10y² - 4x²

10y²  is not a complete square of any number. Hence, option A) is incorrect.

As in option C) 8x² - 40x+25

Neither of the terms in the expression as shown in option C can be a perfect square. Hence, option C) is incorrect.

As in option D) 64x² - 48x+9

The term 48x+9 in the expression as shown in option D can not be a perfect square. Hence, option D) is incorrect.

Lets take the expression 16y² - x²  of option B) and solve it.

First simplify the terms separately to associate them as perfect squares as shown below:

       ⇒  16y² = (4y)²        Equation (1)

       ⇒   x² = (1x)²           Equation (2)

Now, take the difference of Equation (1) and Equation (2).

        ⇒  16y² - x²

          ⇒ (4y)² - (1x)²       Equation (3)

So,

Equation (3 )shows a difference of squares. It can also be represented as factorizing the difference of two perfect squares such as (4y - x) (4y + x).

Which is  

               (4y - x) (4y + x) = 16y² - x²

                                         = (4y)² - (1x)²

So, option B) i.e. 16y² - x² shows a correct difference of squares.

the equation [tex]\(18x - 2x = 4x\)[/tex] step by step:

1. Original equation:

[tex]\[ 18x - 2x = 4x \][/tex]

2. Combine like terms on the left side:

[tex]\[ 16x = 4x \][/tex]

  Explanation: We add or subtract coefficients of like terms. Here,[tex]\(18x - 2x\) simplifies to \(16x\).[/tex]

3. Subtract [tex]\(4x\)[/tex] from both sides:

 [tex]\[ 16x - 4x = 0 \][/tex]

  Explanation: We want to isolate [tex]\(x\)[/tex] on one side. Subtracting [tex]\(4x\)[/tex] from both sides ensures the equation remains balanced.

4. Simplify:

[tex]\[ 12x = 0 \][/tex]

  Explanation: After subtracting, we simplify the expression [tex]\(16x - 4x\) to \(12x\).[/tex]

5. Divide both sides by [tex]\(12\)[/tex]:

[tex]\[ \frac{12x}{12} = \frac{0}{12} \] \[ x = 0 \][/tex]

  Explanation: To solve for [tex]\(x\), we divide both sides by the coefficient of \(x\), which is \(12\).[/tex]

Therefore, the solution to the equation [tex]\(18x - 2x = 4x\) is \(x = 0\)[/tex]. This means [tex]\(x\)[/tex] is zero, satisfying the equation.

Answer:

B.  9, 9x, 18x

Step-by-step explanation:

The value in each box is the product of the row heading and column heading. You can find the missing column heading by dividing the box value (162) by the row heading (18).

The correct terms are 9, 9x, and 18x. Hence, option B is correct.

To factorize the quadratic expression x² + 27x + 162, we need to find two numbers that multiply to 162 (the constant term) and add up to 27 (the coefficient of x). These numbers are 9 and 18.

Identify the constant term (162) and the coefficient of the linear term (27).

Find two numbers that multiply to 162 and add to 27. These numbers are 9 and 18.

Rewrite the middle term using these numbers: x² + 9x + 18x + 162.

Factor by grouping: (x² + 9x) + (18x + 162).

Factor out the greatest common factor from each group: x(x + 9) + 18(x + 9).

Factor out the common binomial factor: (x + 9)(x + 18).

Therefore, the factorization of x² + 27x + 162 is (x + 9)(x + 18).

Based on this factorization, the correct terms from the choices provided are (B) 9, 9x, and 18x.
