The state-space equation that describes the given differential equation y (3) (t) +12y (2) (t) + 3y(¹) (t) + y(t) = x(t) is represented by the matrices A, B, C, and D is [0 1 0; 0 0 1; -1 0 -4], [0; 0; 1], [1 0 0] and 0
To derive a state-space equation for the given differential equation, we first need to convert it into a set of first-order differential equations.
Let us define three state variables:
x1 = y(t)
x2 = y'(t)
x3 = y''(t)
Taking the first derivative of x1 with respect to time, we get:
x1' = x2
Taking the second derivative of x1 with respect to time, we get:
x1'' = x2' = x3
Taking the third derivative of x1 with respect to time, we get:
x1''' = x2'' = -12x2 - 3x3 - x1 + x
Substituting x2 = x1' and x3 = x2' = x1'', we get:
x1' = x2
x2' = x3
x3' = -12x2 - 3x3 - x1 + x
These equations represent the state-space form of the given differential equation. In matrix form, we can write:
x' = Ax + Bu
y = Cx + Du
where
x = [x1, x2, x3]T is the state vector,
u = x4 is the input,
y = x1 is the output,
The matrices A, B, C, and D are given by:
A = [0 1 0; 0 0 1; -1 0 -4]
B = [0; 0; 1]
C = [1 0 0]
D = 0

A magician asks a volunteer to think of two different positive integers without telling her what they are. She then asks him to calculate x, the sum of the larger number with the square of the smaller, and y, the difference between the numbers. The volunteer tells her that x = 9 and y = 3. Find the original numbers.
Answer: 2 and 5.
Step-by-step explanation: We can use algebra to solve for the original numbers. Let's call the smaller number "a" and the larger number "b". From the information given, we know that:
x = b + a^2
y = b - a
The volunteer tells the magician that x = 9 and y = 3. So we can use these values to create a system of equations:
b + a^2 = 9
b - a = 3
To solve for the original numbers, we can first add the two equations together to eliminate b:
a^2 + 2a + 2 = 12
a^2 + 2a = 10
a^2 + 2a - 10 = 0
(a + 5)(a - 2) = 0
This tells us that the two solutions for a are -5 and 2. But since a is a positive integer, we know that it must be 2.
We can now substitute this value of "a" back into the original equations to find "b":
b + a^2 = 9
b + 2^2 = 9
b + 4 = 9
b = 5
So the original numbers are 2 and 5.

After kicking, one coach likes to play practice games with 6 players on each
team. She doesn’t like any team to have more or fewer than 6 players and
she doesn’t like anyone to be left off a team. What are the possible numbers
of players who must show up to practice so that the coach can make these
teams?
Note that the question is about numbers in multiples of 6 or which can be divided equally by 6. Thus the likely number of people who must show up to practice so that the coach can make these teams are 6, 12, 18, 24, 30, 36, 48, and so on. The bottom line is that the number must be a common multiple of 6.
What is the proof that each of the numbers above will create teams of x players each?One way to show that each of the numbers above will equal an exact team of 6 without anyone left off is by dividing each by 6. If we get an integer, then we are correct. Thus:

We can restricted domain of the quadratic(y=x^2 +4) is {-∞,0} or {0,∞}.
What is Quadratic Equation?
Having the form ax^2 + bx + c = 0, quadratic equations are second-degree algebraic expressions. From the term "quad," which meaning square, comes the word "quadratic." A quadratic equation is a "equation of degree 2," to put it another way. A quadratic equation is employed in numerous situations. In addition, there are many uses for quadratic equations in physics, engineering, astronomy, etc.
There are a maximum of two solutions for x in the second-degree quadratic equations. These two solutions for x are denoted as (, ) and are also known as the roots of the quadratic equations.
What is Domain?
The range of values that we are permitted to enter into our function is known as the domain of a function. The x values for a function like f make up this set (x). A function's range is the collection of values it can take as input. After we enter an x value, the function outputs this sequence of values.
It cannot have an inverse function because the largest exponent is even (2), unless the domain is constrained.
We know that the vertex is at x = 0 since our equation is already in vertex form;
a(x - h)^2 + k, or 1(x - 0) + 4

Write the following expression in its

xy

3x + 12x.xy
To write the expression in its simplest form, we need to simplify each term and then combine like terms.
The first term of the expression is 2x²y. This term is already in its simplest form and doesn't require any further simplification.
The second term of the expression is xy. This term is also in its simplest form and doesn't require any further simplification.
The third term of the expression is -3x. This term is also in its simplest form and doesn't require any further simplification.
The fourth term of the expression is 12x.xy. To simplify this term, we need to distribute the 12 over the x and y. So, we get 12x.y.
Now that all terms are simplified, we can combine like terms. Since the terms xy and 12x.y are the same, we can add them together to get (12+1)xy = 13xy.
So, the expression in its simplest form is 2x²y + 13xy - 3x.
We can further simplify the above expression by combining x²y and xy together as (x²+1)xy = x³y
So, the final expression in its simplest form is x³y + 13xy - 3x.

The equation that she can use as statement 5 is c) (3x + 24): 51 = 3x: 85.
To prove that x = 12, Dora must first prove that the segments ST and RQ are parallel. This can be done by showing that the angles formed by their intersection are congruent.
Since the angles, QRT and STP are congruent (statement 2) and the angles SPT and QPR are congruent (statement 3), the Triangle-Angle Angle Similarity Postulate can be applied to show that triangle SPT is congruent to triangle QPR (statement 4).
Now, the corresponding sides of the two triangles must be in proportion in order to prove that x = 12. For this, Dora can use the equation (3x + 24) : 51 = 3x : 85 (statement 5). This equation states that the ratio of the lengths of the corresponding sides of the two triangles is equal to the ratio of 3x to 51 and 3x to 85, respectively.
Since the ratio of the sides of the two triangles must be equal, then 3x + 24 must be equal to 85 and 3x must be equal to 51. Solving for x, we get x = 12, proving that if segment ST is parallel to segment RQ, then x = 12.

Is there a factor on this pls help Questiob : 5x ^ 2 - 8x + 9
Answer:
(5x - 3)(x - 3)
Step-by-step explanation:
Yes, the expression "5x^2 - 8x + 9" can be factored.
One way to factor it is to find the two numbers that multiply to give 9 (the constant term) and add to give -8 (the coefficient of x). These two numbers are 3 and -3.
We can use these two numbers to factor out the common factor (x - 3) from the expression:
5x^2 - 8x + 9 = (5x^2 - 8x) + 9
= (5x^2 - 8x + 9) - 9 + 9
= (5x^2 - 8x + 9) - (3x - 3x)
= (5x - 3)(x - 3)
So the fully factored form of the expression is (5x - 3)(x - 3)
