Answer:
what is the question?
Step-by-step explanation:
The value of the function f(4) is 11.
We have,
To find the value of f(4) for the given function f(x) = 2x + 3,
We substitute x = 4 into the function.
f(4) = 2(4) + 3
= 8 + 3
= 11
We can also see that,
4 is the input and 11 is the output of the function.
Therefore,
The value of the function f(4) is 11.

Which two answer choices below would give you a value of 3 times larger than (820 + 220)?
A) 3(820 + 220)
B) 3(820) + 2(220)
C) 2460 + 660
D) 820 x 220 x 3
The expression that gives you a value of 3 times larger than (820 + 220) are:
3(820 + 220)
2460 + 660
Options A and C are the correct answer.
What is an expression?An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.
Example: 2 + 3x + 4y = 7 is an expression.
We have,
(820 + 220)
= 1040
Now,
3 x 1040
= 3120
Now,
A)
3(820 + 220)
= 3 x 1040
= 3120
B)
3(820) + 2(220)
= 2460 + 440
= 2900
C)
2460 + 660
= 3120
D)
820 x 220 x 3
= 541200
Thus,
3(820 + 220) and 2460 + 660 give the value of 3 times larger than
(820 + 220).

d. 14/11
Answer:
A 5/3
Step-by-step explanation:
The fraction closest to the golden ratio is a. 5/3.
What is a golden ratio?The golden ratio is a ratio between two numbers that approximate 1.618.
It is sometimes referred to as the golden number, the golden proportion, or the divine proportion.
It is closely related to the Fibonacci sequence, a set of numbers where each number is added to the previous one and is typically written as the Greek letter Ф.
From the given options,
5/3 = 1.66.
7/5 = 1.4.
10/8 = 1.25.

Answer:
180 degrees is the answer
Step-by-step explanation:
The rule of an 180⁰ degree rotation is:
(x,y) -> (-x,-y)
So the x and y coordinates change from negative to positive or from positive to negative
9514 1404 393
Answer:
180°
Step-by-step explanation:
When you look at the coordinates, you see that each one has been negated. That is, the image point is in the quadrant opposite the one the preimage point is in.
Every point and its image on a rotated figure makes an angle with the center of rotation that is equal to the angle of rotation. When the preimage and image points are in opposite (not adjacent) quadrants, that angle is 180°.
______
Additional comment
It can be helpful to learn to recognize certain transformations. A rotation of 90° will swap the coordinates and negate one of them. A rotation of 180° negates both coordinates without swapping them.

Piper used 1/5 meter of ribbon to create a border around a triangle if each side of the triangle is the same length how much ribbon did Piper use for each side?
Answer:
[tex]\frac{1}{15}[/tex]
Step-by-step explanation:
as said in the question that the triangle has three equal sides. i.e. this is an equilateral triangle. So,
let us consider one side of the triangle to be x . and 3x( x+x+x) should be equal to 1/5
[tex]x+x+x = \frac{1}{5}\\3x=\frac{1}{5}\\x = \frac{1}{5} / 3\\x = \frac{1}{5} * \frac{1}{3}\\x = \frac{1}{15}[/tex]

B. exponential function.
C. quadratic function.
D. None of the above
Answer:b
Step-by-step explanation:exponential function which means the value is is CONSTANTLY raised to the power
The graph the formula representing the compound interest will be exponential function.
What is graph?
In mathematics, and more specifically in graph theory, a graph is a structure amounting to a set of objects in which some pairs of the objects are in some sense "related".
Given is the equation representing compound interest.
The equation representing the compound interest is -
C = P( 1 + r/n )ⁿˣ
Where -
[P] is principle amount.
[r] is rate.
[x] is time.
The exponential function is eˣ, where [x] is a variable. Similarly, we can graph the formula representing the compound interest as shown in the figure attached. The graph will be exponential in nature.
Therefore, the graph the formula representing the compound interest will be exponential function.
