The area of triangle RST is approximately 94.77 square centimeters.

We have,
To find the area of a triangle RST, we can use the formula for the area of a triangle:

Area = (1/2) x base x height

In this case, we have the lengths of two sides of the triangle (TR = 14 cm and SR = 9 cm) and the measure of an angle (∠SRT = 81 degrees). However, we do not have the height of the triangle directly.

To find the height, we can use trigonometry.

We know that the sine of an angle is equal to the ratio of the length of the side opposite the angle to the length of the hypotenuse.

In triangle RST, the side opposite angle ∠SRT is SR, and the hypotenuse is TR.

sin(∠SRT) = SR / TR

sin(81) = 9 / 14

Now, we can solve for the height (h) using the sine ratio:

h = TR x sin (∠SRT)

h = 14 x sin (81)

Using a calculator, we find h ≈ 13.71 cm (rounded to two decimal places).

Now, we can calculate the area of triangle RST:

Area = (1/2) x base x height

Area = (1/2) x TR x h

Area = (1/2) x 14 cm x 13.71 cm

Area = 94.77 cm² (rounded to two decimal places)

Therefore,

The area of triangle RST is approximately 94.77 square centimeters.

a) the dimension of its column space is also 2. b) the rank of A is 2. c) the nullity of matrix A is 1. d) the dimension of the solution space of the homogeneous system \(A_x = 0\) is also 1.

(a) The dimension of the row space of a matrix is equal to the dimension of its column space. So, if the dimension of the row space of matrix A is 2, then the dimension of its column space is also 2.

(b) The rank of a matrix is defined as the maximum number of linearly independent rows or columns in the matrix. Since the dimension of the row space of matrix A is 2, the rank of A is also 2.

(c) The nullity of a matrix is defined as the dimension of the null space, which is the set of all solutions to the homogeneous equation Ax = 0. In this case, the matrix A is a 3 x 3 matrix, so the nullity can be calculated using the formula:

nullity = number of columns - rank

nullity = 3 - 2 = 1

Therefore, the nullity of matrix A is 1.

(d) The dimension of the solution space of the homogeneous system Ax = 0 is equal to the nullity of the matrix A. In this case, we have already determined that the nullity of matrix A is 1. Therefore, the dimension of the solution space of the homogeneous system \(A_x = 0\) is also 1.

*The x and y is the x and y coordinates for the table

The cost of walking this guest is $190.

The cost of walking the guest can be calculated by adding up the expenses incurred by the hotel.

The guest was walked to another hotel that charged a room rate of $150. Therefore, the hotel incurred a cost of $150 for the room.

In addition to the room cost, the hotel also paid for the guest's Uber ride to the new hotel, which was $15.

Furthermore, the overbooked hotel gave the guest a gift card worth $25. Although the gift card does not directly represent an expense, it can be considered as an opportunity cost for the hotel, as they could have used that money to cover other costs.

Therefore, the total cost incurred by the hotel for walking the guest is:

The equation of a line is most commonly given in the slope-intercept form.

Slope-Intercept Form

Slope-intercept form is given by the formula y=mx+b, where m is the slope and b is the y-intercept. This form is most commonly used because it is easy to draw a graph from and it is very concise. We already know one of the constants, m = 4. So, to find the equation we need to solve for b.

Solving For b

To solve for b, we need to plug in all of the information that we are given into the formula. We are given 3 pieces of info for this point: y = -8, x = -3, m = 4.

Then, multiply.

Finally, add 12 to both sides.

Now that we know the value of b, we can go back to the formula and plug in both constants, y = 4x + 4.

The probability that the diaper is full given that it has leaked is 0.105

Step-by-step explanation:

The given parameters are;

The percentage of diapers that leak before they are changed = 15%

The percentage of diapers that are full when they get changed = 70%

The percentage of full diapers that that leak = 20%

Therefore, given that the percentage of the changed diapers that are full = 70% and out of the full diapers that leak = 20%

∴ The probability that the diaper is full given that it has leaked = The percentage of diapers that leak before they are changed × The percentage of diapers that are full when they get changed

The probability that the diaper is full given that it has leaked = 15/100 × 70/100 = 21/200 = 0.105

The probability that the diaper is full given that it has leaked = 0.105

Answer:

Perpendicular

Step-by-step explanation:

Let's start by finding the slopes of both lines.

Line A's slope is 3 (this is given).

We can determine line B's slope with the two points given. The slope formula is \(m=\frac{y1-y2}{x1-x2}\). Substitute in the values:

\(m=\frac{1-(-1)}{-3-3}\)

and simplify:

\(m=\frac{2}{-6}\)

So the slope of line A is -1/3.

-1/3 and 3 multiply to -1, so this indicates that the two lines are perpendicular.

Answer:

Perpendicular

Step-by-step explanation:

If Line A passes through the origin with a slop of 3, then Line A would be

y = 3x

For Line B, using the slope/points method, the line would be

y = -1/3x

When graphing these two lines, they intersect as opposite slopes, so therefore this pair of equations would be Perpendicular

Answer: The number 26.5 in the equation represents the average number of pounds that a puppy weighs at 12 weeks of age.

To find the weight of a puppy at 20 weeks of age, we can substitute x = 20 into the equation:

y = 2.5x + 26.5

y = 2.5(20) + 26.5

y = 50 + 26.5

y = 76.5

Therefore, a puppy weighs approximately 76.5 pounds at 20 weeks of age.

The equation y = 2.5x + 26.5 represents a linear relationship between the number of weeks after a puppy's weight is first recorded and the puppy's weight in pounds. Since the coefficient of x is positive, this means that a puppy's weight increases over time. Specifically, the weight increases by 2.5 pounds for each additional week.

However, the equation does not tell us whether a puppy's weight increases during each of the 8 weeks. To determine this, we would need additional information such as the weights of the puppies at different points in time over the 8-week period.

The new ratio of the amounts of Max's rice to Victor's rice to Roman's rice is 2:1:3.

Given, that ratio of rice between max, victor and roman

Ratio : A ratio is an ordered pair of numbers a and b, written a / b where b does not equal 0.

Let the amount of rice that Max, Victor, and Roman have as 3x, 2x, and 4x, respectively.

The total ratio of the amounts of rice is 3+2+4 = 9,

So each "part" of the ratio is 1/9.

If Victor gives 1/4 of his rice to Roman, he will give away

(1/4) × (2x) = 1/2x rice to Roman, and he will be left with

(3/4) × (2x)

= 6/4x

= 3/2x rice.

Roman will receive 1/2x rice from Victor and will have

4x + 1/2x = 9/2x rice in total.

So the new amounts of rice that Max, Victor, and Roman have are 3x, 3/2x, and 9/2x, respectively.

The new ratio of the amounts of rice is (3x):(3/2x):(9/2x).

To simplify this ratio, we can multiply all parts by 2 to get:

6x:3x:9x

And then divide all parts by 3x to get:

2:1:3

Hence, the new ratio of the amounts of Max's rice to Victor's rice to Roman's rice is 2:1:3.

Let's assume the amount of rice Max, Victor, and Roman have are 3x, 2x, and 4x units respectively. Now, if Victor gives 1/4 of his rice to Roman, Victor's amount will decrease by 1/4*2x = 0.5x, therefore, Viktor will have 2x - 0.5x = 1.5x units of rice. So, the new ratio of the amount of rice Max to the amount of rice Victor will be 3x:1.5x or, simplifying, 2:1.

If f: rn → rm is a linear map, then its derivative is simply the map itself. This is because a linear map is a function that preserves vector addition and scalar multiplication.

In other words, if we take two vectors in the domain and add them together, and then apply the linear map, it is the same as applying the linear map to each vector separately and then adding the results. Similarly, if we multiply a vector in the domain by a scalar and then apply the linear map, it is the same as multiplying the result of applying the linear map to the original vector by the same scalar.
Formally, we can express this idea using the concept of a Jacobian matrix. The Jacobian matrix of a function describes the rate at which the function changes near a particular point. For a linear map, the Jacobian matrix is simply the matrix that represents the map. This means that the derivative of f is the matrix A such that f(x) = Ax for all x in rn.
To see why this makes sense, consider the simplest case of a linear map from R1 to R1, given by f(x) = ax, where a is a constant. The derivative of this function is f'(x) = a, which is just the constant coefficient of the linear map. More generally, the derivative of a linear map f: rn → rm is the matrix A such that f(x) = Ax for all x in rn.

The probability to answer 5 questions correctly from 14 true or false questions is 0.1222

The given situation represents a binomial experiment, where there are only two possible outcomes for each trial: success (answering correctly) and failure (answering incorrectly). To find the probability of a particular number of successes, we use the binomial probability formula:

P(x)= nCx × p^x × q^(n-x)

Where, n is the total number of trials, p is the probability of success on each trial, q is the probability of failure on each trial (1-p), and x is the number of successes desired.

n = 14 (total number of questions)

p = 1/2 (probability of answering correctly when guessing randomly), and q = 1/2 (probability of answering incorrectly when guessing randomly).

To find P(5), we substitute these values in the formula

P(5) = 14C5 * (1/2)^5 * (1/2)^9= 2002 * (1/32) * (1/512)= 2002 / 16384≈ 0.1222

The probability of rolling a four with the loaded die is 1/3.

To find the probability of rolling a four with a loaded die, we need to determine the likelihood of that specific outcome occurring.

In this case, we are told that a four is three times as likely to occur as the other numbers. This means that the probability of rolling a four is three times greater than the probability of rolling any other number on the die.

Let's assume that the probability of rolling any other number on the die is represented by "x". Since the probability of rolling a four is three times greater, we can represent it as "3x".

To find the value of "x", we need to consider the total probability of all possible outcomes. In this case, we have six possible outcomes (numbers 1 to 6), and the probability of each outcome must sum up to 1 (or 100%).

Therefore, we can set up the following equation: x + x + x + x + x + 3x = 1.

Simplifying the equation, we have: 6x + 3x = 1.
Combining like terms, we get: 9x = 1.
Dividing both sides by 9, we find: x = 1/9.

So, the probability of rolling any other number on the die (besides a four) is 1/9.

Now, to find the probability of rolling a four, we substitute the value of "x" back into our equation. Since 4 is three times more likely, the probability of rolling a four is:

3 * (1/9) = 3/9

= 1/3.

Therefore, the probability that a four shows up when this loaded die is rolled is 1/3.
Conclusion: The probability of rolling a four with the loaded die is 1/3.

The general solution of the system of differential equations is x = c1e^6t + c2e^2t, where c1 and c2 are constants.

To find the general solution, we first need to find the eigenvalues and eigenvectors of the matrix A = [9 -3; -3 9]. The characteristic equation is det(A - λI) = 0, where I is the 2x2 identity matrix. Solving for λ, we get λ1 = 6 and λ2 = 12.

For λ1 = 6, we have (A - λ1I)v1 = 0, where v1 is the corresponding eigenvector. Solving for v1, we get [1; 1]. Similarly, for λ2 = 12, we have (A - λ2I)v2 = 0, where v2 is the corresponding eigenvector. Solving for v2, we get [-1; 1].

The general solution can now be expressed as x = c1e^(λ1t)v1 + c2e^(λ2t)v2. Substituting the values of λ1, λ2, v1, and v2, we get x = c1e^(6t)[1; 1] + c2e^(12t)[-1; 1]. Simplifying this expression, we get x = c1e^(6t) + c2e^(12t), x = c1e^(6t) - c2e^(12t) for the two components respectively.

From the second statement, we can set up another equation:

y - x = 2

Now we can solve for "x" and "y".

Rearranging the second equation, we get:

y = x + 2

Substituting this value of "y" into the first equation, we get:

2x + (x + 2) = 8
