The degree n Lagrange polynomial that passes through n+1 unique points (x0,y0), (x1,y1),..., (xn,yn) is given by:

[j=0 to n] L(x) [i=0 to n, ij] * yj (x - xi)/(xj - xi) (xj - xi)

We have 5 points in our situation, thus n = 4. We get the following results by plugging the provided points into the Lagrange polynomial formula:

[tex]L(x) = 1*(x-2)(x-3)(x-4)(x-5)/(-1123) + 2(x-1)(x-3)(x-4)(x-5)/(1123) + 4(x-1)(x-2)(x-4)(x-5)/(1123) + 4(x-1)(x-2)(x-4)(x-5)/(1123) (2123)+ 12(x-1)(x-2)(x-3)(x-4)/(432*1)[/tex]

When we simplify this expression, we get:

[tex]L(x) = x^3/3 - 3x^2/2 + 11x/6 - 1[/tex]

As a result, the equation of the curve passing through the given locations is:

[tex]y = x^3/3 - 3x^2/2 + 11x/6 - 1[/tex]

It is worth noting that this equation is a cubic polynomial.

The length of the base is 1/64 and can be simplified to the fraction 1/64 = 1/64 in simplest form.

A fraction is a mathematical expression which represents a part of a whole. It is written as a ratio that compares two numbers, the numerator and denominator. The numerator indicates the number of parts, the denominator indicates the total number of parts that make up the whole. Fractions can be expressed as decimals, percentages, and other forms of representation.

To solve this problem, we must use the formula for area of a triangle. This formula states that the area of a triangle is equal to one-half the product of the base and the height. In this problem, the area of the triangle is given as 1/16 square centimeters. This means that the base times the height must equal 1/8.

To find the length of the base, we must isolate the base from the equation. To do this, we must divide both sides of the equation by the height. This will leave us with the equation base = 1/8/height. Since the height is unknown, we can solve for it by taking the reciprocal of the base. This will give us the equation height = 1/8/base.

Combining both equations, we can solve for the base by multiplying both sides of the equation by 1/8. This will give us the equation base = (1/8)(1/8) = 1/64. The length of the base is 1/64 and can be simplified to the fraction 1/64 = 1/64 in simplest form.

For the given dilation of the polygons the correct answer are The length AB is 2. The length A'B' is 3. The scale factor is Three-halves.

Resizing an item uses a transition called dilation. Dilation is used to enlarge or contract the items. The result of this transformation is a picture with the same shape as the original. Yet, there is a variation in the shape's size. The initial form should be stretched or contracted during a dilatation. The phrase "scale factor" describes this transition.

The distance formula for the coordinates is given as:

d(A, B) = |x1 - x2|

From the figure we observe that,

d(A, B) = |2 - 4|

d(A, B) = |-2|

d(A, B) = 2 units.

Hence, option A is correct.

Also, the length of A'B' is:

d(A', B') = |3 - 6| = |-3| = 3 units.

Hence, option B is correct.

The original shape is called the pre-image in a transformation (in this example, a dilation), and the transformed shape is called the image.

The third response is untrue since the picture is larger than the pre-image.

The scale factor of the images is:

2k = 3

k = 3/2.

Hence, option 4 is correct.

The last option is also false, as the scale factor is already determined.

Hence, for the given dilation of the polygons the correct answer are The length AB is 2. The length A'B' is 3. The scale factor is Three-halves.

Answer:

Mr Drake is right.

Step-by-step explanation:

Because you first decreased it by 10% of the ORIGINAL value.

You then increased it by 10% of the DECREASED value.

The percentages are the same percentages, but on different base amounts.

Simple example:

$100 decreased by 10% of $100 ($10) is $90.

$90 increased by 10% of $90 ($9) is $99.

Answer:

Mr Drake Is correct

Step-by-step explanation:

When you increase something by 10%, you multiply the original value by 1.1. When you decrease it by 10%, you multiply the increased value by 0.9. So the final amount is:

original value x 1.1 x 0.9 = 0.99 x original value

Therefore, the new amount will be slightly smaller than the original amount, and Mr. Drake is correct.

The points for this problem are given as follows:

(1960, 179323175) and (2010, 308745538).

Considering that between 1960 and 2010 there is an increase of 50 in the input, the parameter b is obtained as follows:

b^50 = 308745538/179323175

b = (308745538/179323175)^(1/50)

b = 1.01092581.

Hence:

y = a(1.01092581)^x.

When x = 1960, y = 179323175, hence the parameter a is obtained as follows:

a = 179323175/[(1.01092581)^1960]

The value of ∠2KJM for the rhombus is ∠JKM = 23 + (5a/2).

A parallelogram is a particular instance of a rhombus. The opposing sides and angles in a rhombus are parallel and equal. A rhombus also has equal-length sides on each side, and its diagonals meet at right angles to form its shape. The rhombus is sometimes referred to as a diamond or rhombus. Rhombi or rhombuses are the plural forms of rhombus.

Let us suppose the measure of angle = x.

For rhombus all the four angles are congruent, thus,

∠MLN = (9a + 11)°

∠KLM = (-4a + 66)°

∠JLN = x

∠KLJ = x

The sum of the angles of a quadrilateral is 360 degrees, so:

∠JKL + ∠KLM + ∠MLN + ∠NJL = 360

Since JKL and NJL are vertical angles, they are congruent:

∠JKL = ∠NJL = x

Substituting in the given angles, we get:

x + (-4a + 66) + (9a + 11) + x = 360

2x + 5a + 77 = 360

2x = 360 - 5a - 77

2x = 283 - 5a

x = (283 - 5a)/2

Now, ∠JKM = 180 - ∠JKL

∠JKM = 180 - x

∠JKM = 180 - (283 - 5a)/2

Simplifying, we get:

∠JKM = 23 + (5a/2)

Hence, the value of ∠2KJM for the rhombus is ∠JKM = 23 + (5a/2).

Answer:

∠ ABC = 38°

Step-by-step explanation:

given AB = DB then Δ ABD is isosceles with base angles congruent, that is

∠ BDA = ∠ BAD = 71°

the sum of the 3 angles in Δ ABD = 180° , so

∠ ABC + 71° + 71° = 180°

∠ ABC + 142° = 180° ( subtract 142° from both sides )

∠ ABC = 38°

x=(17,4)^2+(−340,−80)+58y= y^2−20y+68

y=y^2−20y+68

The value of x is 0. This means that [tex]8/10 = 16/20 = 4x+6/4x+11[/tex], so the corresponding sides of triangles abc and def have the same ratio.

The similarity of two triangles can be determined by the ratio of their corresponding sides. In the case of triangles abc and def, the ratio of corresponding sides is [tex]8/10 = 16/20 = 4x+6/4x+11[/tex].

To calculate the value of x, we can use the first two ratios and cross-multiply. With 8/10 = 16/20, we get 8*20=16*10, which simplifies to 160=160. Therefore, the first two ratios are equal.

To calculate the value of x using the third ratio, we can use the same method. With 4x+6/4x+11, we get ([tex]4x+6)*(4x+11)=4x^2+44x+66[/tex]. This simplifies to [tex]4x^2+44x+66=4x^2+44x+66[/tex], so the third ratio is also equal.

What is a Circle?

A circle is simply a round shape that has no corners or line segments. It is a closed curve shape in geometry. The points of circle are at a fixed distance from the center.

So now, to calculate the surface area of each jar, we need to find the area of the circular top and the area of the rectangular side.

The area of the circular top can be calculated using the formula for the area of a circle:

[tex]A=\pi r^{2}[/tex], where r is the radius of the circle.

The diameter of the jar is given as 7 cm, so the radius is half of that:

r = [tex]\frac{7}{2}[/tex] cm = 3.5 cm

Therefore, the area of the circular top is:

A_top = [tex]\pi r^2[/tex] = π[tex](3.5)^{2}[/tex] = 38.48 [tex]cm^{2}[/tex]

The area of the rectangular side can be calculated using the formula for the area of a rectangle:

A_side = base x height

The base of the rectangle is the circumference of the circular top, which can be calculated using the formula:

C = 2πr

C = 2π(3.5) = 22 cm

So the base of the rectangle is 22 cm, and the height is 11 cm, since that is the height of the jar.

Therefore, the area of the rectangular side is:

A_side = base x height = 22 cm x 11 cm = 242 [tex]cm^{2}[/tex]

To find the total surface area of each jar, we can add the area of the circular top and the area of the rectangular side:

A_total = A_top + A_side = 38.48 [tex]cm^{2}[/tex]+ 242 [tex]cm^{2}[/tex] = 280.48 [tex]cm^{2}[/tex]

For 12 jars, the total surface area of plastic wrap needed would be:

So, the calculation would be:

Overall increase in account balance - Total amount withdrawn = Total amount deposited

$1,692.45 - $1,876.23 = -$183.78

This means that Ivy actually spent more than she earned during the time period shown on the statement. Therefore, we cannot determine the amount of each of her paychecks with the given information.
