Given the function f(x, y) = x²y(5x - y²), we can find the following: (a) f(1, 3), (b) f(-5, -1), (c) f(x+h, y), and (d) f(x, x).

(a) To evaluate f(1, 3), we substitute x = 1 and y = 3 into the function:

f(1, 3) = (1²)(3)(5(1) - 3²) = 3(3)(5 - 9) = -54.

(b) Similarly, to evaluate f(-5, -1), we substitute x = -5 and y = -1 into the function:

f(-5, -1) = (-5)²(-1)(5(-5) - (-1)²) = 25(-1)(-25 + 1) = -600.

(c) To find f(x+h, y), we replace x with (x+h) in the function:

f(x+h, y) = (x+h)²y(5(x+h) - y²).

(d) Lastly, to determine f(x, x), we substitute y = x in the function:

f(x, x) = x²x(5x - x²) = x³(5x - x²).

In summary, we found the values of f(1, 3) and f(-5, -1) by substituting the given coordinates into the function. For f(x+h, y), we replaced x with (x+h) in the original function, and for f(x, x), we substituted y with x.

The lines given by hx,y,zi = ht + 4, 4t + 5, t − 2i and hx,y,zi = h2s + 3, s + 1, 2s − 3i do not intersect.

We can determine whether two lines intersect by setting their equations equal to each other and solving for the values of x, y, and z. Setting the given equations equal to each other, we have:

ht + 4 = h2s + 3

4t + 5 = s + 1

t − 2 = 2s − 3

From the second equation, we have s = 4t - 4. Substituting this into the third equation, we get t = 3. Then, using t = 3 in the first equation, we get h = -1/3. Substituting these values into the second equation, we get s = 8. However, using these values in the first equation leads to a contradiction: -1/3 ≠ 19/3. Therefore, the lines do not intersect.

Therefore, the lines given by hx,y,zi = ht + 4, 4t + 5, t − 2i and hx,y,zi = h2s + 3, s + 1, 2s − 3i do not intersect.

Answer:

6.1% of 40 is 2.4

Step-by-step explanation:

You can find the percentage by looking at 40 as 100% and then taking 6.1% of that. That is adding 6.1 to 0, so it's just 6.1%.

It would be like asking what is 10% of 30? 30 is 100%, so 10% becomes 3, which would be your answer.

Answer:

6.1\ 100 = x/40

6.1*40= 244

Based on the calculations, the volume of this pyramid is equal to 1440 cm³.

Given the following data:

Length of right triangular base = 9 centimeters and 15 centimeters.

Height of right triangular base = 32 centimeters.

Mathematically, the volume of a pyramid can be calculated by using this formula:

Volume = 1/3 × b × h

Where:

h is the height of a pyramid.

b is the base area of a pyramid.

Substituting the parameters into the formula, we have:

Volume = 1/3 × 9 × 15 × 32

Volume = 3 × 15 × 32

Volume of pyramid = 1440 cm³.

Answer:

The answer is A. 10

Step-by-step explanation:

The two angles are alternate interior angles so they are congruent. Since they are congruent, you can write it in an equation.

5x - 25 = 3x - 5

subtract 3x from each side

2x - 25 = -5

add 25 to each side

2x = 20

divide 2 from each side

x = 10

Also, if you want to check your answer, you can plug 10 back into the equation to see if they're equal.

The relation between the given angles is given by the alternate interior

angles theorem.

If lines p and q are parallel then the value of x is A. 10°

Reason:

The given parameters are;

Condition; Line p, and line q, are parallel.

The angles (3·x - 5)° and (5·x - 25)° are alternate interior angles.

According to alternate interior angles theorem, we have the alternate

angles are congruent, where line p, and line q are parallel.

Therefore;

(3·x - 5)° ≅ (5·x - 25)° By alternate interior angles

(3·x - 5)° = (5·x - 25)° By definition of congruency

Solving, we get;

(3·x - 5)° + 25° = (5·x - 25)° + 25°

3·x + 20° - 3·x = 5·x - 3·x = 2·x

20° = 2·x

\(x = \dfrac{20^{\circ}}{2} = 10^{\circ}\)

The smallest positive solutions for the given modular equations are:

a) x = 10 b) x = 6 c) x = 11

a) For the equation 11 + x ≡ 7 (mod 14), we need to find the smallest positive value of x that satisfies this congruence. We can subtract 11 from both sides of the equation, yielding x ≡ -4 (mod 14). To find the smallest positive value, we add 14 to -4 until we get a positive result. In this case, adding 14 to -4 gives us x ≡ 10 (mod 14), which is the smallest positive solution.

b) In the equation 5x + 1 ≡ 3 (mod 7), we subtract 1 from both sides to obtain 5x ≡ 2 (mod 7). To find the smallest positive value of x, we multiply both sides by the modular inverse of 5 modulo 7. In this case, the modular inverse of 5 is 3, so multiplying both sides by 3 gives us x ≡ 6 (mod 7) as the smallest positive solution.

c) For the equation \(7^x\) ≡ 4 (mod 13), we need to determine the smallest positive value of x. To solve this, we can systematically calculate the powers of 7 modulo 13 until we find one that is congruent to 4. After checking the values, we find that \(7^{11}\) ≡ 4 (mod 13), making x = 11 the smallest positive solution to the equation.

Rei is using boxes of books to barricade a door against zombies. The total weight "w" of the barricade in kilograms is a function of "x", the number of boxes stacked on the table. Each box weighs 30 kilograms, and when there are 8 boxes on the table, the total weight is 310 kilograms. This includes the weight of the table.

To determine the weight of the table alone, we need to subtract the weight of the 8 boxes from the total weight:
Weight of 8 boxes = 8 * 30 kg = 240 kg
Weight of table = Total weight - Weight of 8 boxes = 310 kg - 240 kg = 70 kg
Now that we know the weight of the table, we can define the function "w(x)" for the total weight of the barricade as follows:
w(x) = (30 * x) + 70
This function represents the total weight "w" in kilograms of the barricade as a function of the number of boxes "x" stacked on the table. The function takes into account the weight of each box (30 kg) and the weight of the table (70 kg) to give us the total weight of the barricade with any given number of boxes.

Convert USD to THB, multiply amount of USD by the current exchange rate between USD and THB, which can be found on financial news or currency exchange websites, to get the equivalent amount in THB.

To convert US dollars (USD) to Thai baht (THB), you need to use the current exchange rate between the two currencies. Here are the steps to convert USD to THB:

Find the current exchange rate between USD and THB. This information can be found on financial news websites, currency exchange websites, or by contacting a bank or currency exchange service.

Multiply the amount of US dollars you want to convert by the current exchange rate to get the equivalent amount in Thai baht. For example, if the current exchange rate is 1 USD = 31.50 THB and you want to convert 100 USD to THB, the calculation would be:

100 USD x 31.50 THB/USD = 3,150 THB

Therefore, 100 USD is equal to 3,150 THB.

Note: The exchange rate between USD and THB can fluctuate over time, so make sure to use the current exchange rate for the most accurate conversion.

Answer: 2/5

Step-by-step explanation: 2/5 is the answer bozo

The probability that the 2 boys are seated next to each other will be P(A) = 0.16.

Given is that in a movie theater, 2 boys and 3 girls are randomly seated together in a row.

The total number of ways in which all of them can be seated are -

n{S} = (2 + 3) x (2 + 3) = 5 x 5 = 25

n{S} = 25

The total number of ways in which two boys can be seated together are -

n{A} = 4

So, the probability that the 2 boys are seated next to each other will be -

P(A) = n(A)/n(S)

P(A) = 4/25

P(A) = 0.16

Therefore, the probability that the 2 boys are seated next to each other will be P(A) = 0.16.

Answer:

Step-by-step explanation:

We will make a table and fill it in according to the information provided. What this question is asking us to find, in the end, is how long did it take the cars to travel the same distance. In other words, how long, t, til car 1's distance = car 2's distance. The table looks like this:

              d     =      r     *     t

car1

car2

We can fill in the rates right away:

             d       =      r     *     t

car1                       40

car2                       60

Now it tells us that car 2 leaves 3 hours after car 1, so logically that means that car 1 has been driving 3 hours longer than car 2:

            d     =      r      *      t

car1                     40         t + 3

car2                     60           t

Because distance = rate * time, the distances fill in like this:

                   d      =      r      *      t

car1    40(t + 3)    =      40        t+3

car2          60t     =       60         t

Going back to the interpretation of the original question, I am looking to solve for t when the distance of car 1 = the distance of car 2. Therefore,

40(t+3) = 60t and

40t + 120 = 60t and

120 = 20t so

t = 6 hours.
