Consider the given pseudo code. Write the function T(n) in terms of the number of operations, and then give the asymptotic (big Oh) complexity of the algorithm, show all the work you do. [ write the summation formula and solve it, or use the "Look for pattern"method. a. Matrix Multiplication
The function T(n) in terms of the number of operations is:
T(n) = 2n^3 + 3n^2 + 2n + 1 and the asymptotic complexity of the matrix multiplication algorithm is O(n^3).
To analyze the provided pseudo code for matrix multiplication and determine the function T(n) in terms of the number of operations, we need to examine the code and count the number of operations performed.
The pseudo code for matrix multiplication may look something like this:
```
MatrixMultiplication(A, B):
n = size of matrix A
C = empty matrix of size n x n
for i = 1 to n do:
for j = 1 to n do:
sum = 0
for k = 1 to n do:
sum = sum + A[i][k] * B[k][j]
C[i][j] = sum
return C
```
Let's break down the number of operations step by step:
1. Assigning the size of matrix A to variable n: 1 operation
2. Initializing an empty matrix C of size n x n: n^2 operations (for creating n x n elements)
3. Outer loop: for i = 1 to n
- Incrementing i: n operations
- Inner loop: for j = 1 to n
- Incrementing j: n^2 operations (since it is nested inside the outer loop)
- Initializing sum to 0: n^2 operations
- Innermost loop: for k = 1 to n
- Incrementing k: n^3 operations (since it is nested inside both the outer and inner loops)
- Performing the multiplication and addition: n^3 operations
- Assigning the result to C[i][j]: n^2 operations
- Assigning the value of sum to C[i][j]: n^2 operations
Total operations:
1 + n^2 + n + n^2 + n^3 + n^3 + n^2 + n^2 = 2n^3 + 3n^2 + 2n + 1
Therefore, the function T(n) in terms of the number of operations is:
T(n) = 2n^3 + 3n^2 + 2n + 1
To determine the asymptotic (big O) complexity of the algorithm, we focus on the dominant term as n approaches infinity.
In this case, the dominant term is 2n^3. Hence, the asymptotic complexity of the matrix multiplication algorithm is O(n^3).

Determine whether y=3x^2 - 12x + 1 has a minimum or a maximum value. Then find the value
Minimum
-11
Step-by-step explanation:Main concepts:
Concept 1: Identify the type of equation
Concept 2: Identify the concavity (opens up/down)
Concept 3: Finding a vertex of a parabola
Concept 1: Identify the type of equation
First, observe that the equation is a polynomial. This is a type of equation where there may be multiple terms containing an x, where each term with an x is raised to a whole number power, and may be multiplied by a real number. Additionally, there may be a constant term added (or subtracted).
For our equation, \(y=3x^2-12x+1\), the first two terms contain an x, each raised to a whole number power, and are multiplied by a number. Additionally, there is a constant added to the end of the equation. Therefore, this is a polynomial.
The largest power of x in a polynomial is called the "degree" of the polynomial. Since the largest power of x is 2, this is called a second degree polynomial. Another common name for a second degree polynomial is a quadratic equation.
This quadratic equation is already in what is known as "Standard form" \(y=ax^2+bx+c\)
Concept 2: Identify the concavity (opens up/down)
For quadratic equations, the graph of the equation will be a sort of "U" shape" called a parabola. The parabola either opens up or down depending on the "leading coefficient" in the quadratic equation.
The "leading coefficient" of any polynomial is the constant number that is multiplied to x in the term with the highest power. In this case, the leading coefficient is 3.
A parabola opens up or down in correspondence with the sign of the leading coefficient. If the leading coefficient is positive, the parabola opens upward. If the leading coefficient is negative, the parabola opens downward.
Since the leading coefficient is 3, the parabola for our example opens upward. The branches of the "U" will go upward forever, without a maximum. However, the bottom of the "U" will have a minimum value. We are assigned to find this minimum value (how low it goes).
Concept 3: Finding a vertex of a parabola
To find the vertex of a parabola, with an equation in standard form, there are a few methods, but the most straightforward is to use the vertex formula:
\(h=\dfrac{-b}{2a}\)
Where "h" is the x-coordinate of the vertex, and "a" and "b" are the coefficients from the quadratic equation: \(y=ax^2+bx+c\)
\(h=\dfrac{-(-12)}{2(3)}\)
\(h=\dfrac{12}{6}\)
\(h=2\)
So, the parabola will have a vertex with an x-coordinate of "2", meaning that the lowest point will be at a position that is 2 units to the right of the origin... however, we still don't know how high that minimum is. Fortunately, the equation \(y=3x^2-12x+1\) itself gives the relationship between any x-value and the y-value that is associated with it.
\(y=3x^2-12x+1\)
\(y=3(2)^2-12(2)+1\)
\(y=3*4+(-12)*2+1\)
\(y=12+-24+1\)
\(y=-11\)
So, the vertex of the parabola is (2,-11).
The height of the vertex is -11, so the value of the minimum is -11.
Side note: "What is the value of the minimum" is a different question that "where is the minimum at". The minimum is at 2. The actual value of the minimum is -11.

a police department reports that the probabilities that 0, 1, 2, and 3 burglaries will be reported in agiven day are0.53,0.35,0.10, and0.02, respectively. find the standard deviation for the probabilitydistribution. round the answer to two decimal places
The standard deviation for the probability distribution is approximately 0.79, rounded to two decimal places.
To find the standard deviation for this probability distribution, we first need to find the mean.
The mean is given by:
μ = Σ(x * P(x))
where x is the number of burglaries and P(x) is the probability of x burglaries being reported in a given day.
\(μ = (0 * 0.53) + (1 * 0.35) + (2 * 0.10) + (3 * 0.02)μ = 0 + 0.35 + 0.20 + 0.06μ = 0.61\)
So the mean number of burglaries reported in a given day is 0.61.
To find the standard deviation, we use the formula:
\(σ = √(Σ[(x - μ)^2 * P(x)])\)
where σ is the standard deviation.
\(σ = √[((0 - 0.61)^2 * 0.53) + ((1 - 0.61)^2 * 0.35) + ((2 - 0.61)^2 * 0.10) + ((3 - 0.61)^2 * 0.02)]\\σ = √[(0.61^2 * 0.53) + (0.39^2 * 0.35) + (1.39^2 * 0.10) + (2.39^2 * 0.02)]\\σ = √[0.197969 + 0.053865 + 0.257199 + 0.113964]\\σ = √0.623997σ ≈ 0.79\)
Therefore, the standard deviation for the probability distribution is approximately 0.79, rounded to two decimal places.

B) 421.3 ft2
C) 425.1 ft2
D) 432.9 ft2
E) 443.4 ft2
pls show work
Answer:
E. 443.4 ft²
Step-by-step explanation:
Since it is a regular triangle, it means all three sides are of equal lengths and all angles are of the same degree measure.
Therefore, all sides = 32 ft each
Each equal angle = 60° (sum of all angles = 180)
The area of the triangle can be calculated using the formula, ½*a*b*sin(C),
Where,
a = 32 ft
b = 32 ft
C = 60°
Plug in the values
Area = ½*32*32*Sin(60)
Area = 443.4 ft² (nearest tenth)

Answer: B: 11
Step-by-step explanation:
Just to the quiz for it
An equation is formed of two equal expressions. The number of players going to the tournament is 11.
What is an equation?An equation is formed when two equal expressions are equated together with the help of an equal sign '='.
Since the cost of the van is fixed, therefore, 231. Thus, the two equations can be written as,
P × x = 231(P-4.50)×(x+3)=231Solving the above two equations we will get,
Px + 3P - 4.50x -13.5 = 231
3P - 4.50x - 13.5 = 0
3P - 4.50x = 13.5
3(231/x) - (4.50x) = 13.5
693 - 4.50x² = 13.5x
-4.50x² - 13.5x + 693 = 0
x² + 3x - 154 = 0
x = -14, 11
Since the number of members can not be negative, the number of players going to the tournament is 11.

students. There are only 15 drivers, so the total number of vehicles that they can take must be 15. How
many of each vehicle will Mindy's qass need to transport everyone?!
a. Write a system of equations to describe the situation.
Answer:
Step-by-step explanation:
150 students van holds 8 students small bus holds 14 students
with only 15 drivers you can only have 15 vehicles
v = vans b = buses
eq 1) v + b = 15
eq 2) 8v + 14b = 150
eq 1) into eq 2) the combined equations
v = 15 - b ----> 8v + 14b = 150 ----> 8(15 - b) + 14b = 150
8(15 - b) + 14b = 150 solve for b
120 - 8b + 14b = 150 collect terms and subtract 120 from both sides
120 -120 + (14 - 6)b = 150 -120
6b = 30
b = 30/6
b = 5
noe find the number of vans
v + b = 15
v = 15 - b
v = 15 - 5
v = 10

Answer:
210
Step-by-step explanation:
Hi,
Split this up. Find the area of the rectangle first. To find the area of the rectangle, you need to multiply the L x W
So...
L x W
18 x 10
Area: 180
Now, you need to find the area of the two right triangles. For the first one, to find the area, it's 1/2bh.
So...
We know that 24 - 18 will give us the length of the right triangle. We get... 6 ft.
So...
1/2 (6) (5)
We get 15.
Since both right triangles are the exact same, the other right triangle will also equal 15ft.
Now, add all of the shapes.
15 + 15 + 180 = 210
Your total area is 210.

solve the given differential equation by variation of parameters. 3x2y'' 7xy' y = x2 − x
To solve the given differential equation using variation of parameters, let's first rewrite the equation in standard form:
3x^2y'' + 7xy' - y = x^2 - x
The characteristic equation of the associated homogeneous equation is obtained by setting the coefficients of y'' and y' to zero:
3x^2r^2 + 7xr - 1 = 0
Now, let's solve this quadratic equation for the roots r1 and r2:
Using the quadratic formula: r = (-b ± √(b^2 - 4ac)) / (2a)
a = 3x^2, b = 7x, c = -1
r1 = (-7x + √((7x)^2 - 4(3x^2)(-1))) / (2(3x^2))
r1 = (-7x + √(49x^2 + 12x^2)) / (6x^2)
r1 = (-7x + √(61x^2)) / (6x^2)
r1 = (-7x + √61x) / (6x^2)
r2 = (-7x - √61x) / (6x^2)
The particular solution is given by:
y_p(x) = u_1(x)y_1(x) + u_2(x)y_2(x)
where y_1(x) and y_2(x) are the linearly independent solutions of the associated homogeneous equation, and u_1(x) and u_2(x) are the variation of parameters.
The linearly independent solutions of the associated homogeneous equation are:
y_1(x) = x^(r1) = x^((-7x + √61x) / (6x^2))
y_2(x) = x^(r2) = x^((-7x - √61x) / (6x^2))
Now, we need to find the variation of parameters u_1(x) and u_2(x):
u_1(x) = -∫(y_2(x)f(x)) / (W(y_1, y_2)(x)) dx
u_2(x) = ∫(y_1(x)f(x)) / (W(y_1, y_2)(x)) dx
where f(x) = x^2 - x, and W(y_1, y_2)(x) is the Wronskian of y_1 and y_2.
W(y_1, y_2)(x) = |y_1(x) y_2'(x) - y_1'(x) y_2(x)|
Now, we substitute the values and evaluate the integrals to find u_1(x) and u_2(x).
Finally, the general solution of the differential equation is given by:
y(x) = y_p(x) + C*y_1(x)
where C is an arbitrary constant, and y_p(x) is the particular solution we obtained earlier.
Note: The calculation of the Wronskian and the integrals can be quite involved, so it's recommended to use computational tools or software to assist with the calculations.
