What is the amplitude of the function? Identify the amplitude of a periodic function from its graph. 4 3 2 1
The amplitude of a periodic graph of a function is 2 because the amplitude of the function is half of the difference between the maximum and minimum values of a function.
What is a function?It is defined as a special type of relationship and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.
We have a graph of a function(refer to attached picture)
We know the amplitude of the function is given by:
[tex]\rm Amplitude \ of \ f \ = \frac{1}{2} |max \ f -min \ f|[/tex]
As we can see in the graph the maximum value is 0 and
the minimum value of a function is -4, thus the amplitude
[tex]\rm Amplitude \ of \ f \ = \frac{1}{2} |0 -(-4)|[/tex]
The amplitude of f = 2
Thus, the amplitude of a periodic graph of a function is 2 because the amplitude of the function is half of the difference between the maximum and minimum values of a function.

In each circle, find the value of x. Please help
Answer:
x = 47°
Step-by-step explanation:
First see that Angle W is 90°. Either because T is the center and LS is a diameter. Or because Arc LCS is 180° so Angle W is half that = 90°
Then, see Triangle WSL. The angles in a triangle add up to 180°
90° + x + x-4 = 180°
Subtract 90°
x + x - 4 = 90
Combine the x's
2x - 4 = 90
Add 4
2x = 94
Divide by 2.
x = 47
Utilize graphing to find the solution to

find the value of n such that x^2-19x+n is a perfect square trinomial.
Answer:
1st option
Step-by-step explanation:
x² - 19x + n
using the method of completing the square
add ( half the coefficient of the x- term )² to x² - 19x
x² + 2(- [tex]\frac{19}{2}[/tex] )x + (- [tex]\frac{19}{2}[/tex] )²
with n = (- [tex]\frac{19}{2}[/tex] )² = [tex]\frac{361}{4}[/tex] , then
(x - [tex]\frac{19}{2}[/tex] )² ← a perfect square trinomial
Rewrite the fraction with the indicated denominator.
Answer:
I believe the answerwould be 18/21.
Please let me know if I'm correct!
Hope this helps you!
Hey there!
6/7 = ?/21
= 6/7 = x/21
CROSS MULTIPLY the FRACTION
6(21) = x(7)
6(21) = 7(x)
126 = 7x
7x = 126
DIVIDE 7 to BOTH SIDES
7x/7 = 126/7
CANCEL out: 7/7 because it give you 1
KEEP: 126/7 because it help solve for the x-value
NEW EQUATION: x = 126/7
SIMPLIFY IT!
x = 18
Therefore, your answer is: 18
BECAUSE 18/21 is equivalent to 6/7 and they both give you approximately 86% (or simply 0.86) if you’re rounding your percentage/decimal form
Good luck on your assignment & enjoy your day!

Determine the number of solutions of each system of equations.
Answer:
no solutions
Step-by-step explanation:
x+y = 5
-2x-2y = 10
Multiply the first equation by 2
2x+2y =10
Add this to the second equation
2x+2y =10
-2x-2y =10
0 =20
This is not true so there are no solutions

A swimming pool is shaped like a right rectangle prism. the pool is 36 ft long and 20 ft wide. What is the total amount of water in cubic ft,needed to fill tje pool to a depth 4 ft.
Answer:
2880 ft³
Step-by-step explanation:
T o find the total amount of water that is needed to fill the pool, you have to find the volume of the pool.
Formula to find the volume of a rectangle prism is :
Volume = length × width × height
Let us solve now.
Volume = length × width × height
Volume = 36 ft × 20 ft × 4 ft
Volume = 2880 ft³
Therefore, 2880 ft³ of water is needed to fill the pool.

Answer:
[tex]\implies m\angle A =42\degree[/tex]
Step-by-step explanation:
Quadrilateral ABCD is inscribed in circle with center O.
-> Quadrilateral ABCD is cyclic.
Opposite angles of a cyclic quadrilateral are supplementay.
[tex]\implies m\angle B + m\angle D = 180\degree[/tex]
[tex]\implies (2x)\degree + (3x-5)\degree = 180\degree[/tex]
[tex]\implies (5x-5)\degree = 180\degree[/tex]
[tex]\implies 5x-5= 180[/tex]
[tex]\implies 5x= 185[/tex]
[tex]\implies x= \frac{185}{5}[/tex]
[tex]\implies x= 37[/tex]
[tex]\implies m\angle A =(x+5)\degree[/tex]
[tex]\implies m\angle A =(37+5)\degree[/tex]
[tex]\implies \huge{\orange{m\angle A =\boxed{42}\degree}}[/tex]
