Answer:

7.5×1041.25×10−9 = 78,084.75 = 7.808475 x^10

Step-by-step explanation:

To compute the characteristic polynomial p(λ) for the matrix A, we need to find the determinant of (A - λI), where λ is the eigenvalue and I is the identity matrix.

The matrix (A - λI) is:

A - λI = [20 - λ, 16; -24, -20 - λ]

The determinant of (A - λI) is:

det(A - λI) = (20 - λ)(-20 - λ) - (16)(-24)

           = λ^2 + 20λ + 400 + 384

           = λ^2 + 20λ + 784

Therefore, the characteristic polynomial p(λ) is λ^2 + 20λ + 784.

To solve for the roots, we set p(λ) equal to zero and solve the quadratic equation:

λ^2 + 20λ + 784 = 0

Using the quadratic formula:

λ = (-b ± √(b^2 - 4ac)) / (2a)

For the given equation, a = 1, b = 20, and c = 784. Substituting these values into the quadratic formula:

λ = (-20 ± √(20^2 - 4(1)(784))) / (2(1))

  = (-20 ± √(400 - 3136)) / 2

  = (-20 ± √(-2736)) / 2

  = (-20 ± √(2736)i) / 2

Since the discriminant is negative, the roots of the equation are complex numbers. Simplifying the expression:

λ1 = (-20 + √(2736)i) / 2

   = -10 + √(684)i

λ2 = (-20 - √(2736)i) / 2

   = -10 - √(684)i

Therefore, the two eigenvalues of the matrix A, with λ1 < λ2, are:

λ1 = -10 + √(684)i

λ2 = -10 - √(684)i

Answer:

81.25%

Step-by-step explanation:

x = Pablo's money

y = Mary's money

y + 0.2x = 1.25×0.8x = x

y = 0.8x

or

x = y/0.8 = 1.25y

her money is 80% of his money, or in other words, he has 25% more money than her to begin with.

but now she gives him 20% of her money.

x + 0.2y = a × 0.8y

1.25y + 0.2y = a×0.8y

1.45y = a×0.8y

a = 1.45/0.8 = 1.8125 = 81.25%

if she gives him 20% of her money, he would then have 81.25% more money than her.

As similarity theorem, the value of x that will make the triangles similar by SSS similarity theorem is 77.

Similarity theorem:

In math, similarity theorem refers the line segment splits two sides of a triangle into proportional segments if and only if the segment is parallel to the triangle's third side.

Given,

Here we need to find the t value of will make the triangles similar by the similarity theorem.

For example, we are told that the 2 triangles are similar by SSS theorem.

Here we know that, SSS means Side - Side -Side and it is a congruence theorem which states that the 3 corresponding sides of two triangles have same ratio, then we can say that the two triangles are congruent by SSS theorem

Therefore, in the triangles ,applying the SSS postulate gives;

=> x/35 = 44/20

Then by applying the multiplication property of equality, let us multiply both sides by 35 to get;

=> x = (44 * 35)/20

When we simplify this one then we get,

=> x = 77

Therefore, the value of x is 77.

Step-by-step explanation:

The equation 480t = 1200 can be used to find the number of hours an aircraft takes to reach a destination that is 1200 miles away.

The correct answer is option (C) 480t = 1200.

"An equation is a mathematical statement that is made up of two expressions connected by an equal sign."

speed = distance / time

For given question,

An aircraft flies at a speed of 480 miles per hour and takes t hours to reach its destination.

Let d represents the distance(in miles) traveled by an aircraft in t hours with a speed of 480 miles per hour.

By using the formula of speed,

⇒ 480 = d/t

When destination is 1200 miles away.

This means d = 1200 miles.

⇒ 480 = 1200/t

⇒ 480t = 1200                      .....................(Multiplying both the sides by t)

This equation can be used to find the number of hours it takes the aircraft to reach a destination that is 1200 miles away.

There are 22 people who sent the chain letter, and 189 people did not continue the chain.

We know that the chain started with one person who sent it to 7 others, so that makes a total of 8 people in the first round. In the second round, each of those 7 people could either send it to 7 more people or ignore it, so there are two possibilities for each of those 7 people: they either continue the chain or they don't.

Therefore, there are 2⁷ = 128 possible outcomes for the second round.

If we assume that everyone who received the letter in the second round sent it to 7 more people, then there would be 7 x 128 = 896 people in the third round.

Continuing this pattern, we can see that the number of people in each round is given by the formula of combination 8 x 7ⁿ⁻¹, where n is the round number (starting with n = 1 for the first round).

We want to find the round number such that the total number of people in the chain is 211. Setting the formula above equal to 211 and solving for n gives

8 x 7ⁿ⁻¹ = 211

7ⁿ⁻¹ = 26.375

n - 1 = log_7(26.375)

n = 2.78 (rounded to two decimal places)

Since we can't have a fractional round number, we can assume that the chain ended after the second round (since the third round would have too many people). Therefore, the total number of people who sent the letter is

8 + 7(2) = 22

To find the number of people who did not continue the chain, we can subtract the number of people who sent the letter from the total number of people in the chain

211 - 22 = 189

Therefore, 189 people did not continue the chain.

The value of S, which represents the length of each side of the square, is 4 miles.

To find the value of S, we need to determine the length of each side of the square. Given that the perimeter of the square is 16 miles, we can use the formula for the perimeter of a square, which is 4 times the length of a side.

Perimeter = 4 × S

Given that the perimeter is 16 miles, we can substitute this value into the equation:

16 = 4 × S

To solve for S, we divide both sides of the equation by 4:

16 ÷ 4 = S

4 = S

Therefore, S, which stands for the square's side lengths, has a value of 4 miles.

So, S = 4 miles.

This means that each side of the square measures 4 miles, and the square has equal sides and right angles at each corner.

Answer:

b. a translation 5 units [right] and 2 units down

Step-by-step explanation:

Start with Figure N. The figure is now transformed into Figure O. Notice that Figure O has the same size, shape, and orientation as Figure N. That means there is no scaling, no mirror reflection, and no rotation. There is only a translation.

The upper right vertex of Figure N is now the upper right vertex of Figure O.

The coordinates of the upper right vertex went from (0, 4) to (5, 2).

The x-coordinate went from 0 to 5.

5 - 0 = 5

A translation of 5 in x is a translation of 5 units to the right.

The y-coordinate went from 4 to 2.

2 - 4 = -2

A translation of -2 in y is a translation of 2 units down.

Answer: b. a translation 5 units [right] and 2 units down

(I think you left out the word "right" in choice b.)

The correct statement for transformation should be "a translation 5 units right and 2 units down". Option B is correct.

The given two figures are formed by the transformation.

The initial figure has the base at (-4,1) and (-3,1) which is shifted to (1,-1) and (2,-1), respectvely.

So, the transformation of x coordinate is,

\(1-(-4)=5\rm\;units\)

And transfrmation of y coordinate is,

\(-1-1=-2\rm\;units\)

The figure is not rotated at any angle as they both are identical in orientation.

From the above discussion, it can be concluded that the figure is translated by 5 units towards the right (as it is positive), and by 2 units down (as it is negative).

Therefore, the correct statement for transformation should be "a translation 5 units right and 2 units down". Option B is correct.

To find the displacement and total distance traveled by the object from t=0 to t=6, we need to integrate the velocity function over the given time interval.

The displacement can be found by integrating the velocity function v(t) with respect to t over the interval [0, 6]. The integral of v(t) represents the net change in position of the object during this time interval.

The total distance traveled can be determined by considering the absolute value of the velocity function over the interval [0, 6]. This accounts for both the forward and backward movements of the object.

Now, let's calculate the displacement and total distance traveled using the given velocity function v(t) = t^2 - (1/t) - 12 over the interval [0, 6].

To find the displacement, we integrate the velocity function as follows:

Displacement = ∫[0,6] (t^2 - (1/t) - 12) dt.

To find the total distance traveled, we integrate the absolute value of the velocity function as follows:

Total distance = ∫[0,6] |t^2 - (1/t) - 12| dt.

By evaluating these integrals, we can determine the displacement and total distance traveled by the object from t=0 to t=6.

The pattern that occurs d⁹⁵/dx⁹⁵ sin(x)  is -cos(x)

To find the derivative of d^95/dx^95 sin(x), we can use the fact that the derivative of sin(x) is cos(x) and that the derivative of cos(x) is -sin(x). Therefore, the pattern for the derivatives of sin(x) is:

d/dx sin(x) = cos(x)

d²/dx² sin(x) = -sin(x)

d³/dx³ sin(x) = -cos(x)

d⁴/dx⁴ sin(x) = sin(x)

d⁵/dx⁵ sin(x) = cos(x)

d⁶/dx⁶ sin(x) = -sin(x)

d⁷/dx⁷ sin(x) = -cos(x)

d⁸/dx⁸ sin(x) = sin(x)

We can see that this pattern repeats every 4 derivatives. Therefore, we can simplify the expression d^95/dx^95 sin(x) by dividing 95 by 4 and finding the remainder:

95 ÷ 4 = 23 remainder 3

This tells us that the 95th derivative of sin(x) will be the same as the third derivative of sin(x), which is:

d⁹⁵/dx⁹⁵ sin(x) = d³/dx³ sin(x)

= -cos(x)

Therefore,  the pattern that occurs d⁹⁵/dx⁹⁵ sin(x) is -cos(x).

The defendant was charged with aggravated assault. During the trial, the victim testified that the defendant beat her savagely.

In this case, aggravated assault refers to a more severe form of assault that involves the intentional causing of serious bodily harm to another person. The victim's testimony plays a crucial role in providing evidence and establishing the defendant's guilt. The prosecution will likely present other evidence, such as medical reports or eyewitness testimonies, to support the victim's claim.

It's important to note that the final verdict will depend on the judge or jury's assessment of the evidence presented during the trial. The defense will have an opportunity to cross-examine the victim and present their own evidence or witnesses to challenge the victim's testimony. The defendant's attorney may also argue for a lesser charge or attempt to establish that the defendant acted in self-defense. Ultimately, the court will weigh all the evidence and decide whether the defendant is guilty of aggravated assault based on the standard of proof beyond a reasonable doubt.

The Wigwam Motel in Holbrook, Arizona is famous for its large tepees shaped like cones. the floor space inside each tepee is approximately 153.94 square feet.

(a) To find the slant height of the tepee, we can use the Pythagorean theorem. The slant height is the hypotenuse of a right triangle with the height and the radius of the base as the legs.

The radius of the base is half of the diameter, so r = 14/2 = 7 feet. The height of the tepee is 32 feet. Let's call the slant height "s".

Using the Pythagorean theorem, we have:

s² = r² + h²

s² = 7² + 32²

s² = 49 + 1024

s² = 1073

s = sqrt(1073)

s ≈ 32.77 feet

Therefore, the slant height of the tepee is approximately 32.77 feet.

(b) To find the floor space inside the tepee, we need to calculate the area of the circular base. The formula for the area of a circle is A = πr², where A is the area and r is the radius.

A = π(7)²

A = 49π

A ≈ 153.94 square feet

Therefore, the floor space inside each tepee is approximately 153.94 square feet.

“I should not have to turn the water off while I brush my teeth.”

Step-by-step explanation:

A claim is a statement that expresses the main idea or position of an argument. A claim is usually supported by reasons and evidence to persuade the audience to accept it. A claim can also be challenged or refuted by counterclaims and counterarguments.

To find the claim in the passage, you need to look for the statement that expresses the author’s main idea or position on the topic of turning off the water while brushing teeth. The claim is usually found at the beginning or the end of the passage, but it can also be implied or repeated throughout. In this case, the claim is found at the beginning of the passage:

“I should not have to turn the water off while I brush my teeth.”

This is the claim because it expresses the author’s main idea or position on the topic. The rest of the passage provides reasons and evidence to support this claim, such as hating to brush teeth, finding it annoying to turn off the water, and being only one person who cannot waste much water. These reasons and evidence may not be very convincing or valid, but they still serve to support the claim.

So, the claim in the passage is I should not have to turn the water off while I brush my teeth.
