Step-by-step explanation:

Answer:

10−x)(3x−9)=0

−3x2+39x−90=0

−3(x−3)(x−10)=0

x=3 or x=10

The solutions to the equation (10 - x)(3x - 9) = 0 are x = 10 and x = 3.

Given that the equation (10 - x)(3x - 9) = 0

The factors will have the form (ax + b)(cx + d), where a, b, c, and d are constants.

To find values for a, b, c, and d such that (ax + b)(cx + d) is equal to 0

To determine the solutions of (ax + b)(cx + d),  equate each term to zero and solve for x which gives the solutions.

The two solutions of (ax + b)(cx + d) are -b/a and -c/d.

To find the solutions to the equation (10 - x)(3x - 9) = 0, set each factor equal to zero and solve for x.

Setting (10 - x) = 0 gives:

10 - x = 0

To isolate x, subtract 10 from both sides of the equation:

10 - x - 10 = 0 - 10

Simplifying gives:

-x = -10

Multiplying both sides by -1 to solve for x:

(-1)(-x) = (-1)(-10)

x = 10

So, one solution is x = 10.

Now, setting (3x - 9) = 0, gives:

3x - 9 = 0

To isolate x, we add 9 to both sides of the equation:

3x - 9 + 9 = 0 + 9

Simplifying gives:

3x = 9

Dividing both sides by 3 to solve for x:

(1/3)(3x) = (1/3)(9)

x = 3

Therefore, the second solution is x = 3.

The solutions to the equation (10 - x)(3x - 9) = 0 are x = 10 and x = 3.

The total number of possible words is 155.

How many words are possible? (A word can use a letter more than once, but 0 letters do not count as a word)

There are 5 letters in the mumblian alphabet, and each word must contain 1, 2, or 3 letters.

The number of 1 letter words is 5 since every letter is a word.

The number of 2 letter words is 5 × 5 = 25 because there are 5 options for the first letter and 5 options for the second letter.

The number of 3 letter words is 5 × 5 × 5 = 125 because there are 5 options for the first letter, 5 options for the second letter, and 5 options for the third letter. Therefore, the total number of possible words is:

Thus, we can write that the value of λ=3 is an eigenvalue of the given matrix A and the corresponding eigenvector is v=[-2 5 1]T.

Given matrix is:\($$A = \begin {bmatrix} 2 & 0 & -1 \\ 2 & 2 & 3 \\ -4 & 3 & -4 \end {bmatrix}$$\)Now, to check whether λ = 3 is an eigenvalue of the given matrix A, we will find the determinant of the matrix (A - λI), where I is the identity matrix. If the determinant is zero, then λ is an eigenvalue of the matrix A. The matrix (A - λI) is\(:$$\ {bmatrix} 2 - 3 & 0 & -1 \\ 2 & 2 - 3 & 3 \\ -4 & 3 & -\)end {bmatrix}$$Now, finding the determinant of the above matrix using the cofactor expansion along the first row:$${\begin{aligned}\det(A-\lambda I)&=-1\cdot \begin{vmatrix} -1 & 3 \\ 3 & -7 \end{vmatrix}-0\cdot \begin{vmatrix} 2 & 3 \\ 3 & -7 \end{vmatrix}-1\cdot \begin{vmatrix} 2 & -1 \\ 3 & 3 \end{vmatrix}\\&=-1((1\cdot -7)-(3\cdot 3))-1((2\cdot 3)-(3\cdot -7))\\&=49\end{aligned}}$$Since the determinant is non-zero, hence λ = 3 is an eigenvalue of the matrix A.

Now, to find the corresponding eigenvector, we will solve the equation (A - λI)v = 0, where v is the eigenvector and 0 is the zero vector. The equation becomes:\($$\begin{bmatrix} -1 & 0 & -1 \\ 2 & -1 & 3 \\ -4 & 3 & -7 \end{bmatrix}\begin{bmatrix} x \\ y \\ z \end{bmatrix} = \begin{bmatrix} 0 \\ 0 \\ 0 \end{bmatrix}$$$$\Rightarrow -x - z = 0$$$$2x - y + 3z = 0$$$$-4x + 3y - 7z = 0$$\)Solving the above system of equations using substitution method, we get y = 5z and x = -2z. Taking z = 1, we get the eigenvector as\(:$$v = \begin{bmatrix} -2 \\ 5 \\ 1 \end{bmatrix}$$\)Therefore, λ = 3 is an eigenvalue of the given matrix A and the corresponding eigenvector is v = [-2 5 1]T.

I think that is proportional

First to answer

Answer:

The answer is proportional! The pricing is consistent!

5/2 = 2.5

2.5* 3 = 7.5

Based on the given clues, we can determine the person, drink, and price paid for each individual:

Calvin: Root Beer, $4.99

Dean: Lemonade, $7.99

Kelli: Water, $6.99

Lee: Iced Tea, $5.99

From clue 1, we know that either Calvin or the person who got the Root Beer paid $4.99. Since Calvin paid more than Lee according to clue 4, Calvin cannot be the one who got the Root Beer. Therefore, Calvin paid $4.99.

From clue 2, Kelli paid $6.99.

From clue 3, the person who got the water paid $1 less than Dean. Since Dean paid the highest price, the person who got the water paid $1 less, which means Lee paid $5.99.

From clue 5, the person who got the Root Beer paid $1 less than the person who got the Iced Tea. Since Calvin got the Root Beer, Lee must have gotten the Iced Tea.

Therefore, the final assignments are:

Calvin: Root Beer, $4.99

Dean: Lemonade, $7.99

Kelli: Water, $6.99

Lee: Iced Tea, $5.99

Step-by-step explanation:

Leah has 2/5 gallons of paint. She decides to use 1/4 of this paint to

a door. What fraction of a gallon of paint does she use for the door.

To find out what fraction of a gallon of paint Leah uses for the door, we need to multiply the amount of paint she has (2/5 gallons) by the fraction of the paint she uses for the door (1/4).When we multiply two fractions, we multiply the numerators (top numbers) together, and then the denominators (bottom numbers) together. The result is the product of the two fractions, which is also a fraction.

So,Leah uses (2/5) × (1/4) = (2 × 1) / (5 × 4) = 2/20Since 2 and 20 have a common factor of 2, we can simplify this fraction by dividing the numerator and denominator by 2:2/20 = 1/10Therefore, Leah uses 1/10 of a gallon of paint to paint the door. To summarize: Leah uses 1/10 gallon of paint to paint the door.

(A) Circular orbits of stable particles are possible at radii greater than three times the Schwarzschild radius for the non-rotating spherically symmetric mass.

This represents the radius of a black hole's event horizon, within which nothing can escape. The Schwarzschild radius is the event horizon radius of a black hole with mass M.

M can be calculated using the formula: r+ = 2Mwhere r+ is the radius of the event horizon.

(B)  1/2 M -1/2 3M (²) ¹² (1-³) dT = R³ R. This is the required expression.

Tau is the proper time of the particle moving around a circular orbit. Hence, by making use of the formula given above:1/2 M -1/2 3M (²) ¹² (1-³) dT = R³ dt.

(C) Time passes differently in different gravitational fields, and it follows that the period as measured at infinity should be larger than that measured by the particle.

The principle of equivalence can be defined as the connection between gravitational forces and the forces we observe in non-inertial frames of reference. It's basically the idea that an accelerating reference frame feels identical to a gravitational force.

(D) The period of the orbit as measured by an observer at infinity is 16π M^(1/2) and the period of the orbit as measured by the particle is 16π M^(1/2)(1 + 9/64 M²).

The period of orbit as measured by an observer at infinity can be calculated using the formula: T = 2π R³/2/√(M). Substitute the given values in the above formula: T = 2π (8M)³/2/√(M)= 16π M^(1/2).The period of the orbit as measured by the particle can be calculated using the formula: T = 2π R/√(1-3M/R).

Substitute the given values in the above formula: T = 2π (8M)/√(1-3M/(8M))= 16π M^(1/2)(1 + 9/64 M²).

This is a classic example of a right triangle trigonometry problem, where the angle and one of the sides are given and the goal is to find the length of the hypotenuse.

To solve this problem, we can use the trigonometric function of sine, cosine, or tangent to find the length of the ladder.

To solve this problem, we can use the trigonometric function of sine, cosine, or tangent to find the length of the ladder. In this case, we can use the sine function, as we have the opposite side (the height of the triangle, which is the distance from the ground to the point where the ladder is leaning against the wall) and we want to find the hypotenuse (the length of the ladder). The sine of the angle is the ratio of the opposite side to the hypotenuse. Using this formula, we can calculate the length of the ladder by multiplying the height by the reciprocal of the sine of the angle. Therefore, the length of the ladder is 17/sin(60°) or approximately 19.65 feet.

rubber chips costs $52.50 per square foot

We need to find the area of the playground,

The length: 8ft

The width: 4 ft

=> the area of it is: 8*4 = 32 square foot.

The base: 3 ft

The height: 2 ft

=> the area of it is = 1/2*3*2 = 3 square foot.

The base: 3 ft

The height: 3 ft

=> the area of it is = 1/2*3*3 = 9/2 square foot.

=> the total area of the playground is: 32 + 3 + 9/2 = 39.5 square foot.

So the total cost to install the rubber chips is:

= 39.5 * $52.5

= $2075.75

Hope it will find you well.

The $2625 is the cost to install the rubber chips if each unit represents 1 ft. Installing the rubber chips costs $52.50 per square foot.

It is defined as the area occupied by the rectangle in two-dimensional planner geometry.

The area of a rectangle can be calculated using the following formula:

Rectangle area = length x width

First, we find the area of the rectangle = (8+3)×4 = 44 square feet

Area of the two triangle = 2(1/2)[2×3] = 6 square feet

Area of the complete figure = 44+6 = 50 square feet

Each unit represents 1 ft. Installing the rubber chips costs $52.50 per square foot.

Total cost = 50×52.50 = $2625

Thus, the $2625 is the cost to install the rubber chips if each unit represents 1 ft. Installing the rubber chips costs $52.50 per square foot.

\(2(3 + 3g) >12 + 4m \\ 6 + 6g > 12 + 4m \\ 6 - 12 > - 6g + 4m \\ - 6 > - 6g + 4m\)

Answer:

\(9\; \rm m\).

Step-by-step explanation:

Assume that the run of this rafter is level. Then the height of the ridge (the line with a question mark next to it in the diagram) should be perpendicular to the line marked with \(\rm 12\; m\). The three labelled lines in this diagram will form a right triangle.

Hence, the height of this ridge can be found with the Pythagorean Theorem. By the Pythagorean Theorem:

\((\text{First Leg})^2 + (\text{Second Leg})^2 = (\text{Hypotenuse})^2\).

In this particular right triangle:

\((\text{Height})^2 + (12\; \rm m)^2 = (15\; \rm m)^2\).

\((\text{Height})^2 = (15\; \rm m)^2 - (12\; \rm m)^2\).

Therefore, the height of this ridge would be \(\sqrt{81}\; \rm m = 9\; \rm m\). (Note the unit.)

Let the speed of the southbound train be x mph. then the speed of the northbound train will be x - 14 mph.

Both trains are traveling in the opposite direction and going away from each other.

The distance traveled by southbound train in 3 hours will be 3x miles. The distance traveled by southbound train will be 3(x - 14) miles.

Therefore, the sum of distance covered by both the trains will be equal to 498 miles.

Thus, the speed of the southbound train is 90 mph and the speed of the northbound train is 76 mph.

(a) is: Let t denote the number of text messages and c the charge, in dollars, (b) The formula is c(t) = 49.99 + 0.10(t - 100).

(a) In this case, we will let t denote the number of text messages and c represent the charge, in dollars.

(b) To write a formula for the cell phone charges as a function of the number of text messages (assuming t is at least 100), we will consider the flat monthly rate of $49.99 and the extra charges of $0.10 per text message after the first 100 messages. The formula will be:

c(t) = 49.99 + 0.10(t - 100)

This formula calculates the total charge, c(t), based on the number of text messages, t. The first 100 text messages are included in the flat monthly rate of $49.99, so we subtract 100 from the total number of text messages, t, and multiply the result by the extra charge per text message, $0.10. Then we add the flat monthly rate of $49.99 to get the total charge, c(t).

The statue is about 9.8 - 1.5 = 8.3 meters taller than Kimberly.

What is height?

Height typically refers to the measurement of how tall or high something or someone is, usually measured from the ground or a given baseline. It is often used as a physical descriptor of an object or person, and can be measured in various units such as feet, meters, or inches. Height can also be used to describe the vertical extent or distance of an object or structure, such as the height of a building or the height of a mountain.

We can use the Pythagorean theorem to solve the problem.

Let h be the height of the statue. Then, we have:

h² = 4² + 9²

h² = 16 + 81

h² = 97

h ≈ 9.8

Therefore, the statue is about 9.8 - 1.5 = 8.3 meters taller than Kimberly.
