the expression for 5,364 in terms of x is 5x³ + 3x² + 6x + 4, where x = 10.

why it is and what is multiple?

a) The number 5,364 can be written as the sum of multiples of powers of 10 as follows:

5,364 = 5 × 1,000 + 3 × 100 + 6 × 10 + 4 × 1

= 5 × 10³ + 3 × 10² + 6 × 10¹ + 4 × 10⁰

(b) If x = 10, then we can write 5,364 as:

5,364 = 5 × 10³ + 3 × 10² + 6 × 10¹ + 4 × 10⁰

= 5x³ + 3x² + 6x + 4

Therefore, the expression for 5,364 in terms of x is 5x³ + 3x² + 6x + 4, where x = 10.

A multiple is a product of a given number and any other whole number. In other words, if a number 'a' can be expressed as the product of another number 'b' and a whole number 'c', then 'a' is a multiple of 'b'. For example, 10 is a multiple of 5 because 10 can be expressed as 5 multiplied by 2. Similarly, 15 is a multiple of 3 because 15 can be expressed as 3 multiplied by 5.

The two lines are parallel because both have equal slope.

What area parallel lines?

If two lines do not cross one another anywhere on the plane, they are considered to be parallel. All parallel lines are spaced equally apart from one another.

Numerous forms have parallel lines running along their edges. In the rectangle below, the single and double arrow lines, as well as their junction points, are parallel to one another. Additionally, it is possible to create both horizontal and vertical shapes.

Given : line 1  : y=5x+1

          line 2 :  2y-10x+3=0

                       2y = 10x - 3

We know that, parallel lines always have equal slope.

The slope can be found by using formula :

     coefficient of y / coefficient of x

So, here, line 1 has slope = 2/10 = 1/5

and, line 2 has slope = 1/5

So, both have same slopes hence, both are parallel lines.

The axis of symmetry of a quadratic function can be found by taking the negative of the coefficient of the x term, and then dividing it by 2. In this case, the coefficient of the x term is -2, so the axis of symmetry is located at x = -1.

The key features of the quadratic function are the vertex, the y-intercept, and the x-intercepts. To find the vertex, substitute the x-value for the axis of symmetry into the equation. In this case, the vertex is located at (x, y) = (-1, 27).

The y-intercept is found by setting x = 0 and solving for y. This gives us y = -24, so the y-intercept is located at (0, -24).

To find the x-intercepts, set y = 0 and solve for x. In this case, the x-intercepts are located at (2, 0) and (6, 0).

Step-by-step explanation:

Vertical angles, corresponding angles, and alt. ext. angles

To prove that {f € C°([0,1]) ||. f()dx = 0} is a vector space, we need to verify the following properties:

Closure under addition: Let f,g be two functions in {f € C°([0,1]) ||. f()dx = 0}. Then, for any x € [0,1], we have:

(f+g)(x) = f(x) + g(x)

Now, we can calculate the integral of (f+g)(x) from 0 to 1 as follows:

∫0^1 (f+g)(x) dx = ∫0^1 f(x) dx + ∫0^1 g(x) dx

Since f and g are in the set {f € C°([0,1]) ||. f()dx = 0}, we know that ∫0^1 f(x) dx = 0 and ∫0^1 g(x) dx = 0. Therefore, we have:

∫0^1 (f+g)(x) dx = 0

This means that f+g is also in the set {f € C°([0,1]) ||. f()dx = 0}, and thus the set is closed under addition.

Closure under scalar multiplication: Let f be a function in {f € C°([0,1]) ||. f()dx = 0} and let r be a scalar. Then, for any x € [0,1], we have:

(rf)(x) = r*f(x)

Now, we can calculate the integral of (rf)(x) from 0 to 1 as follows:

∫0^1 (rf)(x) dx = r*∫0^1 f(x) dx

Since f is in the set {f € C°([0,1]) ||. f()dx = 0}, we know that ∫0^1 f(x) dx = 0. Therefore, we have:

∫0^1 (rf)(x) dx = 0

This means that rf is also in the set {f € C°([0,1]) ||. f()dx = 0}, and thus the set is closed under scalar multiplication.

Existence of zero vector: The zero vector is the function f(x) = 0 for all x € [0,1]. This function clearly satisfies the condition that ∫0^1 f(x) dx = 0, and thus it is in the set {f € C°([0,1]) ||. f()dx = 0}.

Existence of additive inverse: Let f be a function in {f € C°([0,1]) ||. f()dx = 0}. Then, the additive inverse of f is -f(x) for all x € [0,1]. This function clearly satisfies the condition that ∫0^1 -f(x) dx = -∫0^1 f(x) dx = 0, and thus it is also in the set {f € C°([0,1]) ||. f()dx = 0}.

Since all the four properties are satisfied, we can conclude that {f € C°([0,1]) ||. f()dx = 0} is a vector space under the usual addition and scalar multiplication of functions.

The possible numbers of hours Yolanda could rent the boat is 6 hours.

The term "inequality" is used in mathematics to describe a relationship between two expressions or values that is not equal to one another. Inequality results from a lack of balance. When two quantities are equal, we use the symbol '=', and when they are not equal, we use the symbol. If two values are not equal, the first value can be greater than (>) or less than (), or greater than equal to () or less than equal to ().

Here the given boat cost per hour = $7.

Offer he gets = $3.

Now writing a inequality then, t represent number of hours,

There are 64 different two-digit numbers that can be formed using the digits 3,9,4,7,6,1,2 and 8 with repetition.

To see why, note that there are 8 possible choices for the first digit (any of the 8 given digits can be used) and 8 possible choices for the second digit (again, any of the 8 given digits can be used). Therefore, by the multiplication principle of counting, there are 8x8=64 possible two-digit numbers that can be formed.

To find all possible two-digit numbers, simply list all possible combinations of the given digits, allowing repetition. One example would be: 11, 12, 13, ..., 98, 99.

Alternatively, you can use the formula for counting with repetition, which is n^k where n is the number of choices for each digit and k is the number of digits. In this case, n=8 (since there are 8 possible digits) and k=2 (since we want two-digit numbers). Therefore, the total number of possible two-digit numbers is 8^2=64.

The solution of the given system is x = -5/2, y = 2, and z = 13/2.

To determine whether the given system is inconsistent, dependent, or neither, we need to solve the system using any of the methods, such as substitution or elimination.

The given system is:
4x + y + 4z = 4
5x - y + 3z = 5
x - 2y - z = 0

Let's use the elimination method to solve the system.

Multiply the first equation by 2 and subtract the second equation from it to eliminate the y variable.
8x + 2y + 8z = 8
5x - y + 3z = 5
-------------------
3x + 5z = 3

Multiply the third equation by 2 and subtract it from the second equation to eliminate the y variable.
5x - y + 3z = 5
2x - 4y - 2z = 0
-------------------
3x + y + 5z = 5

Subtract the equation obtained in step 1 from the equation obtained in step 2 to eliminate the x variable.
3x + y + 5z = 5
3x + 5z = 3
----------------
y = 2

Substitute the value of y in the third equation to find the value of z.
x - 2(2) - z = 0
x - 4 - z = 0
x + z = 4

Substitute the value of y in the second equation to find the value of x.
5x - (2) + 3z = 5
5x + 3z = 7

Substitute the value of x + z in the equation obtained in step 5.
5(4 - z) + 3z = 7
20 - 5z + 3z = 7
2z = 13
z = 13/2

Substitute the value of z in the equation obtained in step 4 to find the value of x.
x + (13/2) = 4
x = 4 - (13/2)
x = -5/2

Therefore, the solution of the given system is x = -5/2, y = 2, and z = 13/2. Since the system has a unique solution, it is neither inconsistent nor dependent. Hence, the given system is neither inconsistent, dependent, nor neither.

The expected net gain (or loss) for playing one game is -$3.125, which rounds to -$3.25. The correct answer is d. -$3.25.

I am a question answering bot and do not have personal experiences to share. However, I can help you find the expected net gain (or loss) for playing one game in this scenario.

First, let's calculate the probability of each possible outcome:
- Probability of winning: 1/8
- Probability of placing 2nd or 3rd: 2/8
- Probability of placing 4th through 8th: 5/8

Next, let's calculate the net gain (or loss) for each possible outcome:
- Net gain for winning: $125 - $25 = $100
- Net gain for placing 2nd or 3rd: $0 (since you receive your money back)
- Net gain for placing 4th through 8th: -$25 (since you lose your money)

Finally, let's use these probabilities and net gains to calculate the expected net gain (or loss) for playing one game:
Expected net gain = (Probability of winning) x (Net gain for winning) + (Probability of placing 2nd or 3rd) x (Net gain for placing 2nd or 3rd) + (Probability of placing 4th through 8th) x (Net gain for placing 4th through 8th)
= (1/8) x ($100) + (2/8) x ($0) + (5/8) x (-$25)
= $12.50 + $0 - $15.625
= -$3.125

Therefore, the expected net gain (or loss) for playing one game is -$3.125, which rounds to -$3.25. The correct answer is d. -$3.25.

Your coordinates of your Y-intercept is where the line crosses over the Y line (the vertical line). This means your x (x,y) is always going to be 0 and your y is going to be the number in which the line crosses over your Y-line.

The interval on which the temperature was over 100°F is (0.79, 1.26).

To find the interval on which the temperature was over 100°F, we need to solve the inequality T(t) > 100.
First, let's rearrange the equation to isolate t:
T(t) = [4t / (t²+1)] + 98.6 > 100
[4t / (t²+1)] > 1.4
4t > 1.4(t²+1)
0 > 1.4t² - 4t + 1.4
Now we can use the quadratic formula to find the values of t that make this inequality true:
t = [-(-4) ± √((-4)² - 4(1.4)(1.4))] / [2(1.4)]
t = (4 ± √(16 - 7.84)) / 2.8
t ≈ 1.26 or t ≈ 0.79
Therefore, the temperature was over 100°F between the interval (0.79, 1.26).

Among Luc, Deborah, and Melanie, the ratio in which the profit was shared is 2:3:7.

Let us assume that the ratio in which the profit shared among the three partners is L:D:M,

We know that the total profit for the year is = R176496,

We also know that Luc received R29416 and

Melanie received R102956.

So, Deborah profit share is calculated as;

⇒ Deborah's share = Total profit - Luc's share - Melanie's share

⇒ Deborah's share = R176496 - R29416 - R102956

⇒ Deborah's share = R44124,

So, now we know that the ratio of the profit shared among the three partners is:

⇒ L:D:M = R29416 : R44124: R102956

To simplify this ratio, we can divide all the amounts by R14708,

To find out how much of each mixture Donny should combine to make 6 kg of a mixture of 33% almonds, we need to use a system of equations. Let x be the amount of the first mixture and y be the amount of the second mixture.

The first equation represents the total amount of the mixtures:

x + y = 6

The second equation represents the amount of almonds in the mixtures:

0.40x + 0.25y = 0.33(6)

Solving the system of equations, we get:

0.40x + 0.25y = 1.98

0.40x + 0.25(6 - x) = 1.98

0.40x + 1.50 - 0.25x = 1.98

0.15x = 0.48

x = 3.2

Substituting the value of x back into the first equation:

3.2 + y = 6

y = 2.8

How to do ordering of rock layers ?

Ordering of rock layers, also known as stratigraphy, is a process of arranging rock layers in a specific order based on their age and location. There are several principles that geologists use to determine the relative ages of rock layers:

Law of superposition: In an undisturbed sequence of rocks, the oldest rocks are at the bottom and the youngest rocks are at the top.

Principle of original horizontality: Layers of sediment are originally deposited horizontally, and any deformation of these layers must have occurred after deposition.

Principle of cross-cutting relationships: Any feature that cuts across a rock or rock layer is younger than the rock or layer that it cuts across.

Principle of inclusions: Any rock fragments included in another rock layer must be older than the rock layer that contains them.

Ordering of given rock layers :
