What is the range and domain of a function?A function's range is the set of all values that the function accepts, and its domain is the set of all values for which the function is defined.
The domain is for the independent variable while the range is for the dependent variable.
Given a table of dependent(x) and independent variable (y)
Now the domain is set of the dependent variable so x {3,2,1,-1} so it is decreasing between two points so it is an interval.
Now in the independent variable (x)
If we multiply by 0.25 then the next term will come so it has a common factor of 0.25.
Hence "Yes; the domain values are at regular intervals and the range values have a common factor of 0.25".

a circle has a center at . the point is on the circle. what is the area of the circle to the nearest tenth of a square unit?
Answers
So area of the Circle ≈ 157.1 sq. unit .
Area is the quantity that expresses the extent of a region on the plane or on a curved surface. The area of a plane region or plane area refers to the area of a shape or planar lamina, while surface area refers to the area of an open surface or the boundary of a three-dimensional object.
Distance formula, Algebraic expression that gives the distances between pairs of points in terms of their coordinates (see coordinate system). In two- and three-dimensional Euclidean space, the distance formulas for points in rectangular coordinates are based on the Pythagorean theorem.
Point P(3,7) is on the Circle having Centre C(8,2).
Therefore, the Distance between points P and C is the radius r of the circle. To calculate r, use the distance formula .
Therefore, [tex]r^2=(8-3)^2+(2-7)^2=50[/tex]
∴ Area of the Circle =π×[tex]r^{2}[/tex]≈ (3.1416) ×(50)=157.08≈ 157.1 sq. unit ( nearest tenth).

Find the values of x and y that make these triangles congruent by the HL theorem
Answers
Answer:
A. x = 3, y = 2
Step-by-step explanation:
The hypotenuse and the length of one leg of one right triangle must be equal to the hypotenuse and corresponding length of the one leg of the other ∆ for both triangles to be equal by the HL Congruence Theorem.
Thus, let's find x and y by setting the corresponding lengths of the two right ∆s equal to each other.
Therefore:
x = y + 1 ----› eqn. 1
2x + 3 = 3y + 3 ----› eqn. 2
Substitute x = (y + 1) into eqn. 2, and solve for y.
2x + 3 = 3y + 3 ----› eqn. 2
2(y + 1) + 3 = 3y + 3
2y + 2 + 3 = 3y + 3
2y + 5 = 3y + 3
Collect like terms
2y - 3y = -5 + 3
-y = -2
Divide both sides by -1
y = 2
Substitute y = 2 into eqn. 1.
x = y + 1 ----› eqn. 1
x = 2 + 1
x = 3

The graph (x, y) passes through the points (2, $136) and (4, $242). Let x represent the total months and y represent the total charges. The equation is given by:
[tex]y-y_1=\frac{y_2-y_1}{x_2-x_1} (x-x_1)\\\\y-136=\frac{242-136}{4-2}(x-2)\\\\y-136=53(x-2)\\\\y-136=53x-106\\\\y=53x+30[/tex]
For health club B:
The table (x, y) has the points (4, 173) and (6, 23y). Let x represent the total months and y represent the total costs. The equation is given by:
[tex]y-y_1=\frac{y_2-y_1}{x_2-x_1} (x-x_1)\\\\y-173=\frac{237-173}{6-4}(x-4)\\\\y-173=32(x-4)\\\\y-173=32x-128\\\\y=32x+45[/tex]

A) m= 1/55.5g
B) g= 55.5m
C) g= 0.02m
D) g= 166.5/3 m
E) m= 55.5g
Answers
Answer:
A,B,D
Step-by-step explanation:
The equation that represents the relationship between g and m is; y = 55.5x
What is Proportionality?If two objects are proportional to each other, the link between them can be described by y = kx, where ‘k’ is the constant ratio of y-values to corresponding x-values.
Given that the water pump for a swimming pool can move 166.5 gallons of water in 3 minutes.
Here we need to determine the relationship between the water pump and the time for filling.
Consider x to be the number of minutes and y to be the amount of water that follows on the pump.
Then the proportionality is written as,
y = kx
Where k refers to the amount of water that flows in one minute.
Thus, equals,
=> 166.5/3
=> 55.5
Therefore, the value of k is; 55.5.
Hence, the equation that represents the relationship between g and m is; y = 55.5x

Combine and Simplify:
48 (1/4x - 1/3y - 2/6x - 3/8y - 2/3
WRITE 2 WAYS!
Answers
Answer:
Combining and simplifying [tex]48(\frac{1}{4}x-\frac{1}{3}y-\frac{2}{6}x-\frac{3}{8}y-\frac{2}{3})[/tex] we get [tex]\mathbf{-4x-34y-32}[/tex] or we can write as [tex]\mathbf{48(\frac{-x}{12} -\frac{17y}{24}- \frac{2}{3})}[/tex]
Step-by-step explanation:
We need to combine and simplify
[tex]48(\frac{1}{4}x-\frac{1}{3}y-\frac{2}{6}x-\frac{3}{8}y-\frac{2}{3})[/tex]
First we will combine like terms and then perform the mathematical operations like addition or subtraction.
Like terms: terms having same variable
[tex]48(\frac{1}{4}x-\frac{2}{6}x-\frac{1}{3}y-\frac{3}{8}y-\frac{2}{3})[/tex]
Now we take LCM of like terms
[tex]=48(\frac{1}{4}x-\frac{2}{6}x-\frac{1}{3}y-\frac{3}{8}y-\frac{2}{3})\\=48(\frac{x*3-2x*2}{12} +\frac{-y*8-3y*3}{24}- \frac{2}{3})\\=48(\frac{3x-4x}{12} +\frac{-8y-9y}{24}- \frac{2}{3})\\=48(\frac{-x}{12} +\frac{-17y}{24}- \frac{2}{3})\\=48(\frac{-x}{12} -\frac{17y}{24}- \frac{2}{3})[/tex]
Now, we can multiply 48 with terms inside the bracket.
we can simplify the terms if they are both divisible by same number.
[tex]=48(\frac{-x}{12} -\frac{17y}{24}- \frac{2}{3})\\=48(\frac{-x}{12} )-48(\frac{17y}{24})-48(\frac{2}{3}))\\=-4x-34y-32[/tex]
So, Combining and simplifying [tex]48(\frac{1}{4}x-\frac{1}{3}y-\frac{2}{6}x-\frac{3}{8}y-\frac{2}{3})[/tex] we get [tex]\mathbf{-4x-34y-32}[/tex] or we can write as [tex]\mathbf{48(\frac{-x}{12} -\frac{17y}{24}- \frac{2}{3})}[/tex]

What is your monthly take-home pay if your take-home pay is $1034.65 every two weeks? Round intermediate calculations and the final answer to the nearest cent; use 365 days in a year.
Answers
The monthly take-home pay is $2240.83.
What is Algebraic expression ?
Algebraic expression can be defined as combination of variables and constants.
To calculate the monthly take-home pay, we need to first find the annual take-home pay and then divide by 12 (since there are 12 months in a year).
We are given that the take-home pay is $1034.65 every two weeks, which means the total take-home pay for a year can be calculated as follows:
annual take-home pay = 1034.65 * 26 = 26889.9
Next, we divide the annual take-home pay by 12 to get the monthly take-home pay:
monthly take-home pay = 26889.9 / 12 = 2240.825
Rounding this to the nearest cent, we get:
monthly take-home pay = $2240.83
Therefore, the monthly take-home pay is $2240.83.

Stephanie's school is selling tickets to a play. On the first day of ticket sales the school sold 4 adult tickets and 10 student tickets for a total of $150. The school took in $105 on the second day by selling 1 adult ticket and 10 student tickets. What is the price each of one adult ticket and one student ticket?
Answers
Answer:
The price of
1 adult ticket = $15
1 student ticket = $9
Step-by-step explanation:
Let
The price of adult tickets be represented by a
The price of student tickets be represented by s
Therefore:
On the first day of ticket sales the school sold 4 adult tickets and 10 student tickets for a total of $150.
4a + 10s = $150.... Equation 1
The school took in $105 on the second day by selling 1 adult ticket and 10 student tickets.
a + 10s = $105.... Equation 2
a = $105 - 10s
Therefore, we substitute : $105 - 10s = a in Equation 1
4a + 10s = $150.... Equation 1
4($105 - 10s) + 10s = $150
$420 - 40s + 10s = $150
Collect like terms
- 40s + 10s = $150 - $420
-30s = -$270
Divide both sides by -30
-30s/-30 = -$270/-30
s = $9
We find a
a = $105 - 10s
a = $105 - 10($9)
a = $105 - $90
a = $15
Therefore, the price of
1 adult ticket = $15
1 student ticket = $9

the density of a certain material is such that it weighs 9 kilograms for every 7 cubic feet of volume. express this density in pounds per pint.
Answers
The density in pounds per pint is 0.047 pounds per pint
Density is calculated using the formula -
Density = [tex]\frac{mass}{volume}[/tex]
To find the density in pounds per pint, we will convert mass and volume to the respective units.
Converting mass in kilograms to pounds -
1 kilogram = 2.205 pounds
9 kilograms = [tex]\frac{2.205*9}{1}[/tex]
9 kilograms = 19.84 ppounds
Converting volume in cubic feet to pints -
1 cubic foot = 59.844 pints
7 cubic foot = [tex]\frac{59.884*7}{1}[/tex]
7 cubic foot = 418.9 pints
Now, keeping the values in formula to find density
Density = [tex]\frac{19.84}{418.9}[/tex]
Performing division to find density -
Density = 0.047 pounds per pint
Hence, the density in pounds per pint is 0.047.
