The domains of each function are classified as follows:
Function A: Discrete domain.Function B: Continuous domain.What is the domain of a function?
The domain of a function is the set composed by all the input values that are assumed by the function.
For each function in this problem, the inputs are given as follows:
Function A: number of quarters in the jar.Function B: time.Hence, the domain of function A is a discrete domain, as the number of quarters in the jar can assume countable values such as 0, 1, 2, ..., it does not assume decimal values.
For function B, the domain is a continuous domain, as measures of time can assume decimal values, for example, 10.5 minutes.
These differences discussed represent the comparison of the domains of each function.

What is perimeter?For geometry, the perimeter of the shape is defined as the total length of the boundary. The perimeter is determined by adding all the sides and side lengths that enclose the shape. It is measured in units such as centimeters, meters, feet and inches,
For the given question:
JK = [tex]\sqrt{(-3-(-3))^{2}+(-9-7)^{2} }[/tex]
JK = [tex]\sqrt{0^{2} +16^{2} }[/tex]
JK = 16
JL = [tex]\sqrt{(-3-x)^{2} +(-9-(-1))^{2} }[/tex]
JL = [tex]\sqrt{(-3-x)^{2} + 8^{2} }[/tex]
JL = [tex]\sqrt{(-3-x)^{2} + 64}[/tex]
KL = [tex]\sqrt{(-3-x)^{2} + (7-(-1))^{2} }[/tex]
KL = [tex]\sqrt{(-3-x)^{2} + 8^{2} }[/tex]
KL = [tex]\sqrt{(-3-x)^{2} + 64}[/tex]
Since, JK + JL+ KL = 36 [Perimeter of triangle]
As we have already calculated, JK = 16
So, 16 + JL+ KL = 36
JL+ KL = 36 - 16
JL+ KL = 20
Since JKL is an isosceles triangle, JL= KL
So, let's replace KL by JK in the above equation:
JL+ JL = 20
2JL = 20
JL = 10
Now, substitute the value of JL in following equation:
JL = [tex]\sqrt{(-3-x)^{2} + 64}[/tex]
16 = [tex]\sqrt{(-3-x)^{2} + 64}[/tex]
Now square both sides,
256 = (-3-x)² + 64
256-64 = (-3-x)²
192 = (-3-x)²
13.85 = -3-x
x = -3 ± 13.85
x = (-3 - 13.85) (-3 + 13.85)

a) The quadratic equation behind the parabola is y = (4 / 5) · x² - (8 / 5) · x - 1.
b) There are two x-intercepts: x₁ = - 0.5, x₂ = 2.5.
How to derive a quadratic equation and find its x-intercepts
Mathematically speaking, parabolas are represented by quadratic equations, whose standard form is introduced below:
y = a · x² + b · x + c
Where a, b, c are real coefficients.
The values of the three coefficients are found from the knowledge of three distinct points on Cartesian plane. First, choose the three points:
(x₁, y₁) = (- 0.5, 0), (x₂, y₂) = (2.5, 0), (x₃, y₃) = (0, - 1)
Second, construct the system of linear equations with all the given points and the standard form of the quadratic equation:
0.25 · a - 0.5 · b + c = 0
6.25 · a + 2.5 · b + c = 0
c = - 1
Third, solve the system by numerical methods:
(a, b, c) = (4 / 5, - 8 / 5, - 1)
Fourth, write the quadratic equation:
y = (4 / 5) · x² - (8 / 5) · x - 1
The x-intercepts of the quadratic equation are the points of the curve that pass through the x-axis. Then, the x-intercepts are x₁ = - 0.5 and x₂ = 2.5.

Biologists notice an alarming trend in the walleye population in Lake Erie. Despite efforts, the population is decreasing by 15% each year. They estimate the walleye population was 26 million at the beginning of the current year. Write a sequence that lists the population for the first 4 years using 26 million as the first term.
Given:
The initial population is p = 26 million.
The decreasing percentage is r = 15% each year = 0.15.
The objective is to write the sequence of population after 4 years.
Explanation:
The general formula of population decrease is,

The inequality that reflects the given region, according to the Factor Theorem, is:
y< -(x+40)(x+50)
What is the Factor Theorem?When completely factoring polynomials, the factor theorem is employed in mathematics. It is a theorem that relates the factors and zeros of a polynomial. If f(x) is a polynomial of degree n 1 and 'a' is any real number, then (x-a) is a factor of f(x) if f(a)=0.
According to the Factor Theorem, a polynomial function with roots x₁, x₂, ....xₙ is given by
f(x)=a(x-x₁)(x-x₂)...(x-xₙ)
In which a is the leading coefficient.
The roots are given as follows:
x₁=-40, x₂=-50
Hence:
y = a(x + 40)(x +50)
It includes the point (-55,-75), hence:
-75 = a(-55 + 40)(-55 +50)

You want to order posers to advertise your band. A company charges $109.95 for the first 100 posters and $65 for each additional 100 posters.
Write an equation that represents the cost (in dollars) of the posters of the number (in hundreds) of posters ordered (in slope- intercept form).
The equation that represents the total cost as a function of the number (in hundreds) of posters ordered, x is f(y) = 109.95 + 65x
let
y = total cost
x = numbers in hundreds
cost of first hundred = $109.95
Cost of additional hundred = $65
f(y) = 109.95 + 65x
The total cost of 1000 posters
1000 - first hundred = 900
additional hundreds = 900/100= 9
So,
f(y) = 109.95 + 65x
= 109.95 + 65(9)
= 109.95 + 585
= 694.95
f(y) = $694.95
Therefore, the total cost of 1000 posters is f(y) = $694.95

= 3i - i + 1 - 2
= 2i - 1
2) A taxi service charges a fee of $2.50 and then an additional $2.70 per mile. Determine the relationship.
Data:
• Fixed fee: $2.50
,• Additional: $2.70 per mile
Procedure:
The relationship the problem is describing is a linear one with the form:
[tex]y=mx+b[/tex]In this case, we have a fixed fee that is represented by b in the linear equation, and an additional fee represented by m, which depends on the miles (x) travels.
Thus, the equation would be:
[tex]y=2.7x+2.5[/tex]Based on this equation, you can replace any value of miles (x) given to calculate the total price (y).
Sam bought a jacket for $34, which is one-third of the original price. How much did thejacket cost originally?
Let the original cost of the jacket be x.
Now, saying that one-third of the original cost of the jacket is $34, is mathematically equivalent to:
[tex]\frac{1}{3}\times x=34[/tex]Now we have to solve the resulting equation in order to obtain the value of x
This is done as follows:
[tex]\frac{1}{3}\times x=34[/tex][tex]\Rightarrow\frac{x}{3}=34[/tex][tex]\Rightarrow x=3\times34[/tex][tex]x=102[/tex]Therefore, the original cost of the jacket is $102
Which relation is a function?
I’m confused on this. can anyone help me out?
Answer:
The one the u have marked is a function.
Step-by-step explanation:
If you draw a vertical line through each one, each line only goes through one point
frequency The table and corresponding polygon show information about the waiting times of some patients at a dentist. Frequency What fraction of patients waited for more than 7 minutes? 10- 0- 5 6 7 8 Waiting time (x minutes) 9 10 x Waiting time (x minutes) 5< x≤6 6< x≤7 7< x≤8 8< x≤9 9< x≤ 10
The 31 minutes for the lowest quartile of the waiting times of patients at this surgery.
Given that,
The histogram displays statistics about the average patient wait time in dental offices, expressed in minutes. 3.24 frequency The table and related polygon display data regarding some patients' wait periods at a dentist.
We have to find frequency How many patients waited for longer than seven minute.
The frequency of a given data value is the number of times it happens. We use f to represent a data value's frequency. For instance, if five students received As in science, the grade A was said to have a frequency of five.
In the picture we can see the answer.
Therefore, The 31 minutes for the lowest quartile of the waiting times of patients at this surgery.
