Work out the area of the shaded triangle:
The area of the shaded triangle will be 11.5 square centimeters.
What is the area of the shaded region?It deals with the size of geometry, region, and density of the different forms both 2D and 3D.
The area of the square will be given as,
A₁ = 5 x 5
A₁ = 25
The area of the triangles will be given as,
A₂ = 1/2 (1 x 5 + 4 x 3 + 2 x 5)
A₂ = 1/2 (27)
A₂ = 27/2
Then the area of the shaded triangle will be given as,
A = A₁ - A₂
A = 25 - 27/2
A = (50 - 27) / 2
A = 23/2
A = 11.5 square cm
The area of the shaded triangle will be 11.5 square centimeters.

The length of a rectangle is twice its width.
If the perimeter of the rectangle is 36 m, find its area
Answer:
length= 12 width=6
Step-by-step explanation:
when adding perimeter you add the length and width twice each so divide 36 by two and get 18
if the length is twice the width then you could make the equation w+2w=18
by adding like terms you get 3w=18
to get n by itself you divide 18 by 3 and get w=6
if the width is 6 and the length is twice that then the length is 12
Answer:
A=72
Step-by-step explanation:
The length of a rectangle is TWICE it's width meaning 2 times. (Note that L= length, W=width, and A=Area)
L=2w
4w+2w=36
6w=36 <- ( 6 is width)
then
2x6=12
Then
12x6=72
So the area of the rectangle is 72.
Hope that makes sense!

Answer: 16 ft
Step-by-step explanation: The ratio given is 2ft=1in, therefore 2ft/1in=1. Multiplying anything by 1 equals itself, so multiplying 8in*(2ft/1in)=16ft where the number of inches cancel out.

f(x) = cube root 2x
g(x) = 2x + 1
Find (f/g) (X) Include any restrictions on the domain
Answer:
B.
Step-by-step explanation:
any arithmetic operation with functions just means to do this operation with the functional expressions.
f/g is really just the expression of f divided by the expression of g.
so, this results in a fraction with the denominator (bottom part) = 2x + 1
as you know, a division by 0 is not a valid operation, and therefore we have to forbid any value for x that would create a 0 in the denominator.
so, for what x do we get
2x + 1 = 0
2x = -1
x = -1/2
therefore, we have to exclude x = -1/2.

(1) 13
(3) -87
(2)-7
(4) 2}
I need some work or explanation please ASAP
The solution to function f(x) = 4 is 2 1/5.
Given that, f(x) = 5x - 7
Now, function f(x) = 4 implies that
i.e. 5x - 7 = 4
i.e. 5x = 4 + 7
i.e. 5x = 11
i.e. x = 11/5
x =2 1/5
So, option (4) is correct.
The core concept of mathematics' calculus is functions. The unique varieties of relations are the functions. In mathematics, a function is represented as a rule that produces a distinct result for each input x. In mathematics, a function is indicated by a mapping or transformation. Typically, these functions are identified by letters like f, g, and h. The collection of all the values that the function may input while it is defined is known as the domain. The entire set of values that the function's output can produce is referred to as the range. The set of values that could be a function's outputs is known as the co-domain.

The function is f(x)= 5x-7. The solution to f(x)=4 is when x is 11/5.
Given that,
The function is f(x)= 5x-7
A function is nothing but in mathematics, a function is a unique arrangement of the inputs (also referred to as the domain) and their outputs (sometimes referred to as the codomain),where there is exactly one output for every input, and the output can be connected to its input.
f(x), where x is the input, is a common way to refer to a function. A function represented as y = f(x).
We have to find the solution to f(x)=4
Take 5x-7 in the place of f(x) because they are equal.
5x-7=4
5x=4+7
5x=11
x=11/5
Therefore, the solution x value is 11/5.

The function y = -x² + 3x + 4 is negative when - 1 > x > 4.
A function is made up of three parts: a set of inputs, a set of outputs, and a rule that links the components of the input set to the components of the output set so that each input is paired with exactly one output.
Consider the function,
y = - x² + 3x + 4
For the function to be negative y < 0.
Therefore,
- x² + 3x + 4 < 0
- ( x² - 3x - 4 ) < 0
- ( x² - 4x + x - 4 ) < 0
- [ x ( x - 4 ) + 1 ( x - 4 ) ] < 0
- ( x + 1 ) ( x - 4 ) < 0
Multiplying by -1 on each side of the inequality.
- ( x + 1 ) ( x - 4 )(-1) > 0( - 1 )
( x + 1 ) ( x - 4 ) > 0
x < - 1 or x > 4
Therefore, the function is negative when - 1 > x > 4.

In algebraic formulations, numbers are represented by letters or alphabets without their numerical values being specified. The fundamentals of algebra taught us how to represent an unknown value using letters like x, y, and z. Here, these letters are referred to as variables. A mathematical expression may have both variables and constants. A coefficient is any value that is introduced before and increased by a variable.
Let take w= x²-2yz
2yz=x²-w
Divide the equation by 2z.
2yz/2z=(x²-w)/2z
y=(x²-w)/2z
Therefore, The expression with the y subject is y=(x²-w)/2z.

A small publishing company is planning to publish a new book. Let C be the total cost of publishing the book (in dollars). Let N be the number of copies of the book produced. For the first printing, the company can produce up to 200 copies of the book. Suppose that C= 10/N + 800 gives C as a function of N during the first printing. Identify the correct description of the values in both the domain and range of the function. Then, for each, choose the most appropriate set of values.
The domain is the set of all integers lying in the interval [0 , 200] and range is the set of all reals lying in the interval [800 , 2800].
What is a function?
A function defined from A to B, associates each and every element of the set A tò the element of set B. In mathematics, it is represented using the symbol, f : A -> B. Here, set A is called the domain of the function while set B is called the range of a function.
Calculation of domain and range of a given function
The domain is the set of all possible values of x. According to this question, the domain of N lies in the interval [0 , 200] i.e. all the integers lying in the given interval. Only integers are chosen because the number of books cannot be in fraction.
The range is the set of possible costs and lies in the interval [800 , 2800] i.e. all the reals lying in the given interval.
Hence, the domain is the set of all integers lying in the interval [0 , 200] and range is the set of all reals lying in the interval [800 , 2800].

The Sugar Sweet Company will choose from two companies to transport its sugar to market. The first company charges $5500 to rent trucks plus an additional fee of $200.25 for each ton of sugar. The second company charges $5041 to rent trucks plus an additional fee of $225.75 for each ton of sugar.
The computation shows that the tons of sugar when they'll have same price is 18 tons.
How to compute the value?The first company charges $5500 to rent trucks plus an additional fee of $200.25. Thai will be:
= 5500 + (200.25 × s)
= 5500 + 200.25s
where s = tons of sugar
The second company charges $5041 to rent trucks plus an additional fee of $225.75 for each ton of sugar. This will be:
5041 + 225.75s
Then we will equate both of them. This will be:
5500 + 200.25s = 5041 + 225.75s
5500 - 5041 = 225.75d - 200.25s
459 = 25.5s
s = 459/25.5
s = 18
At 18 tons, they'll have same price.
