The measure of angle D is \( 125^{\circ} 88^{\prime} 5^{\prime \prime} \).
The interior angles of a quadrilateral are measured as A \( 51^{\circ} 22^{\prime} 30^{\prime \prime} \), B \( 105^{\circ} 38^{\prime} 48^{\prime \prime} \), C \( 78^{\circ} 10^{\prime} 37^{\prime \prime} \), and D \( 124^{\prime} 46^{\prime \prime} \).
To find the measure of angle D, we can use the fact that the sum of the interior angles of a quadrilateral is 360 degrees.
Add the measures of angles A, B, and C:
\( 51^{\circ} 22^{\prime} 30^{\prime \prime} \) + \( 105^{\circ} 38^{\prime} 48^{\prime \prime} \) + \( 78^{\circ} 10^{\prime} 37^{\prime \prime} \) = \( 234^{\circ} 71^{\prime} 55^{\prime \prime} \)
Subtract the sum of angles A, B, and C from 360 degrees to find the measure of angle D:
360^{\circ} - \( 234^{\circ} 71^{\prime} 55^{\prime \prime} \) = \( 125^{\circ} 88^{\prime} 5^{\prime \prime} \)
Therefore, the measure of angle D is \( 125^{\circ} 88^{\prime} 5^{\prime \prime} \).

\[ \begin{array}{l} f(x)=2 x^{2}+5 \\ f-1(x)= \end{array} \] fx domain \( f x \) range \[ \begin{array}{l} f(x)=\frac{1}{2} x+4 \\ g(x)-6 x-2 \\ f \circ g(x)= \\ g \circ f(x)= \\ f(x)=\frac{1}{x-9} \\
The f(g(x)) is equal to 72x^2+48x+9 and g(f(x)) is equal to 3x+22.
To provide an accurate answer, it's important to first understand what the question is asking for. From the given information, it appears that there are several different parts to this question, so I will address each one individually.
1. Finding f-1(x)
To find the inverse of f(x), we can switch the x and y values and solve for y.
\begin{align*}
f(x) &= 2x^2+5 \\
y &= 2x^2+5 \\
x &= 2y^2+5 \\
2y^2 &= x-5 \\
y &= \sqrt{\frac{x-5}{2}} \\
f^{-1}(x) &= \sqrt{\frac{x-5}{2}}
\end{align*}
Therefore, f-1(x) is equal to √((x-5)/2).
2. Determining fx domain and range
The domain of f(x) is all real numbers since there are no restrictions on the input value x. However, the range of f(x) is limited by the fact that 2x^2+5 is always greater than or equal to 5. Therefore, the range of f(x) is [5,∞).
3. Finding f(g(x)) and g(f(x))
To find f(g(x)), we first need to substitute g(x) into f(x) wherever x appears:
\begin{align*}
f(g(x)) &= 2(g(x))^2+5 \\
&= 2(6x+2)^2+5 \\
&= 72x^2+48x+9
\end{align*}
To find g(f(x)), we first need to substitute f(x) into g(x) wherever x appears:
\begin{align*}
g(f(x)) &= 6f(x)-2 \\
&= 6\left(\frac{1}{2}x+4\right)-2 \\
&= 3x+22
\end{align*}
Therefore, f(g(x)) is equal to 72x^2+48x+9 and g(f(x)) is equal to 3x+22.
4. Explaining f(x)=1/(x-9)
The function f(x)=1/(x-9) is a rational function with a vertical asymptote at x=9. This means that as x approaches 9 from either direction, the function values become increasingly large (either positive or negative infinity).
The domain of f(x) is all real numbers except for x=9 (since dividing by zero is undefined). The range of f(x) is all real numbers except for zero (since 1/0 is undefined).I hope this helps! Let me know if you have any further questions.

The bubble sort algorithm b. fork() system call c. pipe() system call d. pthread_create() and pthread_join() e. shmget(), shmat(), shmdt(), and shmctl() system calls. f. gettimeofday() to time the sorting performance. 2. Study, compile, and run this sequential bubble sort program. It takes an integer argument N, generates a set of N random integers, sorts them in ascending order using bubble sort, and prints the sorted list to standard output. $ seq_bubble 4 Generating 20 10 15 2 Sorted sequence is as follows: 2 10 15 20 3. Now study, compile, and run this even-odd pass variant of sequential bubble sort. You will find this version more amenable to a parallel implementation. 4. Test the above programs with hundreds, thousands, or millions of numbers. Adjust MAX_NUM and MAX_COUNT in the code as needed. 5. You can redirect very large output to a file using the operator to examine later. 6. Use gettimeofday () to measure and print the sorting time for different values of N. . Requirements for parts B and C below. - Use only the C language and glibc, so that you can understand low-level behavior or your code. No other languages, libraries or packages are necessary/allowed. - Do not use any pre-existing bubble-sort implem tions/libraries other than the provided in this assignment. - Implement only a parallel version of bubble sort, NOT any other sorting algorithm, even though there may be other (possibly better) parallel sorting algorithms, such as parallel nes . merge sort .
To test with hundreds, thousands, or millions of numbers, MAX_NUM and MAX_COUNT should be adjusted in the code as needed.
The Bubble Sort algorithm is a simple sorting algorithm that repeatedly steps through a given array, comparing elements and swapping them if they are in the wrong order. The sequential Bubble Sort algorithm can be implemented using a for loop that iterates through the array and swaps the elements if they are in the wrong order. The even-odd pass variant of the Sequential Bubble Sort adds two for loops, one for even elements and one for odd elements, which makes it more amenable to a parallel implementation.
Using multiple processes and threads to implement a parallel version of the Bubble Sort algorithm involves using system calls such as fork(), pipe(), pthread_create() and pthread_join(), and shmget(), shmat(), shmdt(), and shmctl() system calls. When implementing this parallel version of the Bubble Sort algorithm, care must be taken to avoid race conditions by properly synchronizing processes and threads.
To test the sequential and even-odd pass variants of the Bubble Sort algorithm, one should use the gettimeofday() function to measure and print the sorting time for different values of N. To test with hundreds, thousands, or millions of numbers, MAX_NUM and MAX_COUNT should be adjusted in the code as needed, and very large output can be redirected to a file using the operator.

Factor the following polynomial with a negative coefficient. -5x^(6)+15x^(4)+20x^(3)
The factored form of the polynomial is (5x^(3))(-x^(3)+3x+4).
To factor the polynomial with a negative coefficient, -5x^(6)+15x^(4)+20x^(3), we can use the content loaded factor method. This method involves factoring out the greatest common factor (GCF) of all the terms in the polynomial.
The GCF of -5x^(6), 15x^(4), and 20x^(3) is 5x^(3). So, we can factor out 5x^(3) from each term:
-5x^(6) = -(5x^(3))(x^(3))
15x^(4) = (5x^(3))(3x)
20x^(3) = (5x^(3))(4)
Now, we can rewrite the polynomial as:
-5x^(6)+15x^(4)+20x^(3) = (5x^(3))(-x^(3)+3x+4)
So, the factored form of the polynomial is (5x^(3))(-x^(3)+3x+4).
In summary, the polynomial -5x^(6)+15x^(4)+20x^(3) can be factored as (5x^(3))(-x^(3)+3x+4) using the content loaded factor method.

Algebraic expressions can also include constants, which are fixed numbers, and coefficients, which are the numbers that multiply the variables in the expression. For example, in the algebraic expression 3x + 2y, the constants are 3 and 2, and the coefficients are 3 and 2, respectively.
To find the break-even point, we need to determine the number of tickets that need to be sold in order to cover the costs of the party.
Let's start by setting up an equation to represent the total cost of the party as a function of the number of tickets sold:
Total Cost = Room Rental + Entertainment + Decorations + Food Cost - Ticket Sales Revenue
Total Cost = 450 + 20n - 25n
where n is the number of tickets sold.
Simplifying this equation, we get:
Total Cost = 450 - 5n + 20n
Total Cost = 15n + 450
Now, we need to set the total cost equal to the revenue from ticket sales:
15n + 450 = 25n
Subtracting 15n from both sides, we get:
450 = 10n
Dividing both sides by 10, we get:
n = 45
Therefore, the break-even point is 45 tickets. If the organizers sell 45 tickets, the revenue from ticket sales will cover the total cost of the party, including the room rental, entertainment, decorations, and food cost.

What is the highest number of degrees (as a whole number) an image can rotate without returning to it's exact original position?
please answer in __°!
Answer:
359°
Step-by-step explanation:
When an image is rotated by a multiple of 360 degrees, it returns to its original position because it has completed one full revolution. However, if the image is rotated by any angle less than 360 degrees, it will not return to its exact original position.
For example, if an image is rotated by 45 degrees, it will not return to its exact original position, but will instead be in a new and unique position. If the image is then rotated by another 45 degrees, it will again be in a new and unique position, and so on.
Therefore, the highest number of degrees an image can rotate without returning to its exact original position is 359 degrees.
Answer: 359 degrees
Step-by-step explanation:
If you rotate any object exactly 360 degrees, it returns to it's original position. Remember that phrase "360 no-scope?" It involves spinning until you're back where you started; try doing it right now. You'll be back where you were. But this question wants to know how far you can rotate an object without it being back where it was. I would usually say 359.999999999, but it's a whole number answer, so we'll stick with 359.

Determine the area of the parallelogram with vertices(−7,7,6),(−4,9,5),(−10,6,6), and(−7,8,5). Use the square root symbol "∇" where needed to give an exact value for your answer. Area =0
The area of the parallelogram is ∇19.
To determine the area of the parallelogram, we will use the formula: Area = ||u x v||, where u and v are vectors representing two sides of the parallelogram.
First, we need to find the vectors u and v. We can do this by subtracting the coordinates of two adjacent vertices:
u = (−4,9,5) - (−7,7,6) = (3,2,-1)
v = (−10,6,6) - (−7,7,6) = (-3,-1,0)
Next, we need to find the cross product of u and v:
u x v = [(2)(0) - (-1)(-1), (-1)(-3) - (3)(0), (3)(-1) - (2)(-3)] = [-1, 3, -3]
Finally, we need to find the magnitude of the cross product, which will give us the area of the parallelogram:
Area = ||u x v|| = ∇((-1)^2 + (3)^2 + (-3)^2) = ∇(1 + 9 + 9) = ∇19

The trinomial x^(2)+7x-18 factors into and x^(2)-7x-18 factors into The signs in each binomial are
The trinomial [tex]x^(2)+7x-18[/tex] factors into (x+9)(x-2), and the trinomial [tex]x^(2)-7x-18[/tex] factors into (x-9)(x+2). The signs in each binomial are opposite.
In the first trinomial, the signs are positive and negative, while in the second trinomial, the signs are negative and positive. This is because the signs in the binomials are determined by the signs of the constant term and the coefficient of the linear term in the trinomial.
For the first trinomial, the constant term is -18 and the coefficient of the linear term is 7. To factor this trinomial, we need to find two numbers that multiply to -18 and add to 7. The numbers 9 and -2 satisfy this condition, so the trinomial factors into (x+9)(x-2).
For the second trinomial, the constant term is -18 and the coefficient of the linear term is -7. To factor this trinomial, we need to find two numbers that multiply to -18 and add to -7. The numbers -9 and 2 satisfy this condition, so the trinomial factors into (x-9)(x+2).
In both cases, the signs in the binomials are opposite because one of the numbers is positive and the other is negative.

Alex spent One Hour Twenty Minutes less than Lane Reading Last Week Lane spent Fifty Minutes less than Pete pete spent Three Hours Reading How Long did Alex spend Reading
Using unitary method, we can find out that Alex spent 50 minutes reading.
Unitary Method: What is it?By using the unitary technique, we can determine both the value of many units from the value of a single unit as well as the value of multiple units from the value of a single unit.
The worth of many things is supplied in the unitary technique, and we must either determine the value of more or fewer items. To do that, we must first determine the value of a single item by division and then determine the value of further or other items by multiplication.
Given in the question,
Alex spent 1 hour 20 minutes less than Lane.
Lane spent 50 minutes less than Pete.
Pete spent 3 hours reading.
Since, Pete spent 3 hours.
So, Lane spent:
= 3 hours or (180 minutes) - 50 minutes
= 2 hours 10 minutes.
Now, Alex spent:
= 2 hrs 10 minutes - 1 hour 20 minutes
= 50 minutes
Therefore, Alex spent 50 minutes reading.

The state capitals of Santa Fe, Oklahoma City, and Austin are shown in the map below. Abbreviating the cities by their first letter, write a mathematical statement using the Triangle Inequality Theorem to prove the distance from Santa Fe to Austin to Oklahoma City is greater than the distance from Santa Fe to Oklahoma City. (PLEASE HELPPPPP!!)
Using the Triangle Inequality Theorem the correct option is [tex]$SA + AO > SO$[/tex].
What is triangle inequality theorem?
The Triangle Inequality Theorem states that for any triangle, the sum of the lengths of any two sides must be greater than the length of the remaining side. In mathematical notation, for a triangle with sides of lengths a, b, and c, this can be written as:
a + b > c
b + c > a
a + c > b
The correct mathematical statement using the Triangle Inequality Theorem to prove the distance from Santa Fe to Austin to Oklahoma City is greater than the distance from Santa Fe to Oklahoma City is:
[tex]$SA + AO > SO$[/tex]
where:
SA is the distance from Santa Fe to Austin
AO is the distance from Austin to Oklahoma City
SO is the distance from Santa Fe to Oklahoma City
This inequality states that the sum of the distances from Santa Fe to Austin and from Austin to Oklahoma City is greater than the distance from Santa Fe to Oklahoma City.
Therefore the correct option is [tex]$SA + AO > SO$[/tex].

5) A decade of inflation
a) Suppose the annual inflation rate was 3% for 10 years in a row. What was the inflation rate for that decade?
b) Find the inflation rate for the decade from 1960 to 1970. If the inflation rate had been the same for each year in that decade, what would that annual rate have been? The answer to part a) will help you with this problem. This might be difficult depending on your math background, but try to be creative.
The inflation rate for that decade will be 34.39%. If the inflation rate had been the same for each year in that decade, the annual rate would have been 2.79%.
a) If the annual inflation rate was 3% for 10 years in a row, the inflation rate for that decade would be 34.39%. This is calculated by using the formula (1 + annual inflation rate)^number of years - 1. So in this case, it would be (1 + 0.03)^10 - 1 = 0.3439 or 34.39%.
b) To find the inflation rate for the decade from 1960 to 1970, we need to know the Consumer Price Index (CPI) for both years. The CPI for 1960 was 29.6 and the CPI for 1970 was 38.8.
We can use the formula (CPI in later year/CPI in earlier year)^(1/number of years) - 1 to find the annual inflation rate.
So in this case, it would be (38.8/29.6)^(1/10) - 1 = 0.0279 or 2.79%. Therefore, if the inflation rate had been the same for each year in that decade, the annual rate would have been 2.79%.
