The expression 11! / 9!(11-9)! evaluates to 55
How to evaluate numbers with the factorial sign?The symbol ! is called factorial in mathematics.
Factorial can be defined as the product of all positive integers less than or equal to a given positive integer and denoted by that integer and an exclamation point.
Thus, factorial five is written as 5! meaning 5×4×3×2×1
It can also be written in shortened form as 5×4! or 5×4×3!
Let's evaluate 11! / 9!(11-9)! now:
11! / 9!(11-9)! = 11! / 9!(2)!
= 11×10×9! / 9!2!
= 11×10/ 2 (Note: 2! = 2×1 =2 )
= 110/2
= 55
Note: We shortened 11! to 11×10×9! because we want the 9! to cancel out each other. This is usually done to ease the evaluation. Also, note that 0! = 1
Therefore, the result of the evaluation of the expression 11! / 9!(11-9)! is 55

Compute ∫c xe^y dx + x^2 y dy along the line segment x = 4
0≤y≤4
The computed value of a line integral, \(I = \int_C ( x \: e^y dx + x² y) dy \) is equals to the 32
The line integrals form that we can work with the involvement of rewriting in terms of a single variable. During the integrating over a path where one of the variables is constant, then that variable is not actually variable at all, and there is no need to do more. We have a line
integral is \(I = \int_C ( x \: e^y dx + x² y) dy \)
We have to determine its value along line segment x = 4
Now, the line segment is x = 4 that means, dx = 0 and 0≤y≤4. So, substitute all known values in above integral, \(I = \int_C ( x \: e^y dx + x² y) dy \)
\(= \int_{ 0}^{2} x² y dy + 0\)
\(= [ x² \frac{ y²}{2}]_{0}^{2}\)
\(= [ x² \frac{ 2²}{2} - 0]\)
\(= 2x²\)
= 2× 4² = 32
Hence, required value is 32.

Suppose an object is thrown upward with initial velocity of 48 feet per second from a high of 120 feet. The height of the object t seconds after it is thrown is given by h(t)=-16t^2+48t+120. Find the average velocity from t=2 to t=4.
Type your answer as a number with no units.
The average velocity from t = 2s to t = 4s would be - 48 ft/s.
What are algebraic expressions?In mathematics, an expression or mathematical expression is a finite combination of symbols that is well-formed according to rules that depend on the context.
Mathematical symbols can designate numbers (constants), variables, operations, functions, brackets, punctuation, and grouping to help determine order of operations and other aspects of logical syntax.
Given is that an object is thrown upward with initial velocity of 48 feet per second from a high of 120 feet. The height of the object t seconds after it is thrown is given by h(t) = - 16t² + 48t + 120.
Average velocity
Average rate of change of velocity with time is called average velocity. Mathematically -
v{avg.} = Δx/Δt .... Eq { 1 }
Δx = x(4) - x(2)
Δx = - 16(4)² + 48(4) + 120 - {- 16(2)² + 48(2) + 120}
Δx = - 96
Δt = 4 - 2 = 2
So -
v{avg.} = Δx/Δt = -96/2 = - 48 ft/s
Therefore, the average velocity from t = 2s to t = 4s would be - 48 ft/s.

Question 4 Find the composite function for the given functions. fog for f(x) = 4x + 4 and g(x) = x 2 - 9 O 16x2 +8x-4 Ox2-4x-13 Ox²+4x-5 O4x²-32
Question 11 Locate relative maximum and relative min
To find the composite function for the given functions f(x) = 4x + 4 and g(x) = x² - 9, we need to plug in g(x) into f(x).
So, the composite function of fog is:fog(x) = f(g(x))= f(x² - 9)= 4(x² - 9) + 4= 4x² - 36 + 4= 4x² - 32.
Therefore, the composite function for the given functions is 4x² - 32.
Option D is the correct answer.
To locate the relative maximum and relative minimum, we need to find the critical numbers and the second derivative of the function given.
Let's find the critical numbers. To do this, we need to find the derivative of the given function:
f(x) = x³ - 3x² - 9x + 5f'(x) = 3x² - 6x - 9
Setting f'(x) = 0, we get:
3x² - 6x - 9 = 0
Dividing both sides by 3, we get:x² - 2x - 3 = 0
Factoring the equation, we get:x² - 3x + x - 3 = 0(x - 3)(x + 1) = 0.
Therefore, the critical numbers are x = 3 and x = -1.
Let's find the second derivative of the given function:f''(x) = 6x - 6.
Now, we can use the second derivative test to find the relative maximum and relative minimum.
If f''(x) > 0 at x = a, then the function has a relative minimum at x = a. If f''(x) < 0 at x = a, then the function has a relative maximum at x = a. If f''(x) = 0 at x = a, then the test fails and we need to use another method.
f''(3) = 6(3) - 6 = 12 > 0
Therefore, f(x) has a relative minimum at x = 3.
f''(-1) = 6(-1) - 6 = -12 < 0
Therefore, f(x) has a relative maximum at x = -1.
The relative minimum is at x = 3 and the relative maximum is at x = -1.

if two tables have a one-to-many relationship, which of the following do you typically need to add to the table on the "many" side?
When two tables have a one-to-many relationship, you typically need to add a foreign key to the table on the "many" side to link the records to the corresponding record in the "one" table.
In a one-to-many relationship, the table on the "one" side is usually the primary key table, and the table on the "many" side is usually the foreign key table. The foreign key is used to link the records in the "many" table to the corresponding record in the "one" table. This is done by adding a column to the "many" table that contains the primary key value from the "one" table.
When designing a database, it is important to establish relationships between tables to ensure data integrity and avoid redundant data. In a one-to-many relationship, one record in the primary key table can be associated with many records in the foreign key table. To establish a one-to-many relationship, you need to create a primary key in the "one" table and a foreign key in the "many" table. The foreign key is a column that contains the primary key value from the "one" table. For example, if you have a "customers" table and an "orders" table, the "customers" table would be the primary key table and the "orders" table would be the foreign key table. Each record in the "orders" table would have a foreign key column that contains the customer ID from the "customers" table.

You need to download 3 games for your math class. Each game is the same price. Since this is your first time downloading a game from the site, you are also charged a one-time $0.50 access fee. You are charged a total of $4.35. What is the cost of each game? Show your work and round your answer to the nearest cent.
Answer:
Each game costs $1.28.
Step-by-step explanation:
First, we need to find the total of all the games.
Since the only additive is the $0.50, we simply subtract it from the total.
4.35-0.50=$3.85
Since you bought three games, and they're all the same price, we divide $3.85 by 3.
3.85/3=1.2833333
Since were doing it by pennies, we can round it down to $1.28 per game.

a) x-intercepts are _________
b) midpoint of the x-intercepts is ___________
c) the extreme value is _______________
d) f(_) = ______________
Answer:
See belowStep-by-step explanation:
The x-intercepts are the points with y- coordinate of 0
(x - 3)(x + 8) = 0x - 3 = 0 or x + 8 = 0x = 3 or x = - 8a) x-intercepts are
3 and - 8b) midpoint of x-intercepts is
(3 - 8)/2 = - 5/2 = - 2.5c) The extheme value has x- coordinate of - 2.5 and y- coordinate
(-2.5 - 3)(- 2.5 + 8) = (-5.5)(5.5) = - 30.25d) f(- 2.5) = - 30.25
Answer:
\(\sf a) \quad x = -8 \:\:and \:\:x = 3\)
\(\sf b) \quad \left(-\dfrac{5}{2},0\right)\)
\(\sf c) \quad \left(-\dfrac{5}{2},-\dfrac{121}{4}\right)\)
\(\sf d) \quad f(x)=\left(x+\dfrac{5}{2}\right)^2-\dfrac{121}{4}\)
Step-by-step explanation:
Part (a)
The x-intercepts are the x-values when the curve crosses the x-axis, so when the function is equal to zero:
\(\implies f(x)=0\)
\(\implies (x-3)(x+8)=0\)
Therefore:
\((x-3)=0 \implies x=3\)
\((x+8)=0 \implies x=-8\)
Therefore, the x-intercepts are x = -8 and x = 3
Part (b)
\(\textsf{Midpoint}=\left(\dfrac{x_2+x_1}{2},\dfrac{y_2+y_1}{2}\right)\quad \textsf{where}\:(x_1,y_1)\:\textsf{and}\:(x_2,y_2)\:\textsf{are the endpoints}}\right)\)
\(\sf \implies Midpoint=\left(\dfrac{-8+3}{2},\dfrac{0+0}{2}\right)=\left(-\dfrac{5}{2},0\right)\)
Therefore, the midpoint of the x-intercepts is (-5/2, 0)
Part (c)
The extreme value is the vertex. The vertex is:
the minimum point if the parabola opens upwardsthe maximum point if the parabola open downwardsThe x-coordinate of the vertex is the x-value of the midpoint of the x-intercepts. Therefore, the x-value of the extreme value is x = -5/2.
To find the y-coordinate, substitute this into the given equation:
\(\implies \sf y=\left(-\dfrac{5}{2}-3\right)\left(-\dfrac{5}{2}+8\right)=-\dfrac{121}{4}\)
Therefore, the extreme value is:
\(\sf \left(-\dfrac{5}{2},-\dfrac{121}{4}\right)\)
Part (d)
The function in vertex form is:
\(\sf f(x)=\left(x+\dfrac{5}{2}\right)^2-\dfrac{121}{4}\)
\(\begin{aligned}\implies \sf f\left(-\dfrac{5}{2}\right)& = \sf \left(-\dfrac{5}{2}+\dfrac{5}{2}\right)^2-\dfrac{121}{4}\\\\ & = \sf 0 -\dfrac{121}{4}\\\\ & = \sf -\dfrac{121}{4} \end{aligned}\)
