Which graph represents a function?
The graph below shows the total cost for lunch, c, when Will and his friends buy a large salad to share and several slices of pizza, p.
A graph titled Lunch Cost. The x-axis shows the number of slices purchased, numbered 1 to 8, and the y-axis shows the cost in dollars, numbered 5 to 40. Blue diamonds appear at points (0, 7.5), (1, 10), (2, 12.5), (3, 15), (4, 17.5), (5, 20), (6, 22.5), (7, 25), (8, 27.5).
For each additional slice of pizza that is purchased, by how much does the total cost of lunch increase?
$1.50
$2.00
$2.50
$3.00
For each additional slice of pizza that is purchased, the total cost of lunch is increase by $2.5
First choose two points
(1, 10) and (2, 12.5)
The cost of one slice of pizza = $10
The cost of two slice of pizza = $12.5
Using these points we have to find the slope of the line
The slope of the line is the change in y coordinates with respect to the change in x coordinates of the graph
The slope of the line m = [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]
Where m is the slope of the line
[tex](x_1,y_1)[/tex] is the coordinates of the first point
[tex](x_2,y_2)[/tex] is the coordinates of the second point
Substitute the values in the equation
Slope of the line = (12.5 - 10) / (2-1)
= 2.5/1
= $2.5
Hence, for each additional slice of pizza that is purchased, the total cost of lunch is increase by $2.5

Triangle ABC has the following angle measures:
mLA = (x + 6)°, mzB = (3x - 15)°, mzC = (5x +36)°
What is m/C?
The value of ∠C: 121°
What is Triangle?
A polygon with three edges and three vertices is called a triangle. It is one of the fundamental geometric shapes. Triangle ABC is the designation for a triangle with vertices A, B, and C. In Euclidean geometry, any three points that are not collinear produce a singular triangle and a singular plane.
Given this,
There is an ABC triangle.
m∠A = (x + 6)°
m∠B = (3x - 15)°
m∠C = (5x + 36)°
The size of C must be determined.
Having said that,
A triangle's total number of angles equals 180 degrees.
As a result, we can say,
∠(A) + ∠(B) + ∠(C) = 180
(x + 6)° + (3x - 15)° + (5x + 36)° = 180°
(x + 3x + 5x) + (6 - 15 + 36) = 180°
9x + 27 = 180°.
9x = 180 - 27
9x = 153 degrees
x = 153/9 degrees
17 = x.
Hence,
The ∠C is expressed as
∠C = 5x + 36
= 5*17 + 36
= 85 + 36
∠C = 121.
Thus, ∠C = 121.

How to find p-value from z-score?
The procedure to calculate the p-value from z-score depends on one of two choices: one-tailed (which may be Left-tailed or Right-tailed) or two-tailed tests.
How to find the p-value from the z-score?A z-table, otherwise termed the standard normal table, provides the area under the curve to the left of a z-score.
The technique for using z-tables to find p-values depends on the test being carried out; which may be; one- or two-tailed test.
For one-tailed tests, the directionality is also a factor.
It therefore follows that;
For a Left-tailed z-test: the p-value = Φ(Zscore)
For a Right-tailed z-test: the p-value = 1 - Φ(z-score).
For a Two-tailed z-test: the p-value = 2 * Φ(−|z-score|).

For each function, select whether it’s inverse is a function or not a function. refer to the attached picture.
The inverse of the function is also a function for each part.
What is function?
a function from a group X to a group Y assigns to every component of X specifically one component of Y.
Main body:
In order to have an inverse function, a function must be one to one.
In the case of
f(x)=x⁴we find that f(1)=f(−1)=1. So f(x) is not one to one on its implicit domain R.
If we restrict the domain of
f(x) to [0,∞) then it does have an inverse function, namely:
f−1(y)=⁴√y
Some more details...
In general, if you want to find the inverse of a function
f(x) then set y=f(x) and attempt to solve for x.
In our example, put:
y=f(x)=x⁴
Then taking the square root of both ends, allowing for both possible
signs we find:
±√y=x²
Assuming that we are only interested in real values of x, we require the left hand side to be non-negative, so assume the non-negative square root.
Then take the square root of both sides again to get:
±√√y=x
That is:
x=±√√y=±⁴√y
Note that this does not give us a unique value of x in terms of y.So the inverse function is not defined, unless we have a restriction such as x≥0, i.e. restrict the domain of f(x) to be [0,∞).
Hence y = x⁴ has inverse and its inverse is also function.

What is Angles?
In Euclidean geometry, an angle is the shape created by two rays that share a terminus and are referred to as the angle's sides and vertices, respectively. The plane that contains the rays contains the angles created by two beams. The meeting of two planes might also result in an angle. Dihedral angles are what these are.
We can write
(6x + y) = (x + 5y)
[By corresponding angles]
6x + y = x + 5y
6x - x = 5y - y
5x = 4y
x = 4y/5
Now by linear pair
4x + (6x + y) = 180
4x + 6x +y = 180
10x + y = 180
By putting the value of x
10(4y/5) + y = 180
8y + y = 180
9y = 180
y = 180/9
y = 20°

What is an ordered pair?An ordered pair is made up of the ordinate and the abscissa of the x coordinate, with two values given in parenthesis in a certain sequence.
Pair in Order = (x,y)
x is the abscissa, the distance measure of a point from the primary axis x
y is the ordinate, the distance measure of a point from the secondary axis y
Given are two equations 2x - y = 0 and 5x + 3y = 22.
The ordered pair (7, 19) is not a solution to this system as these two equations do not intersect each other at (7, 19).

Estimate the average by first rounding to the nearest 100:
120, 230, 455, 175
Answer:
250.
Step-by-step explanation:
First we need to round to the nearest 100:
120 rounded to the nearest 100 is 100.
230 rounded to the nearest 100 is 200.
455 rounded to the nearest 100 is 500.
175 rounded to the nearest 100 is 200.
So, we have the numbers 100, 200, 500, and 200.
To find the average of numbers, we need to add them up and divide the number we get by how many numbers we added:
100 + 200 + 500 + 200 = 1,000
Since we added 4 numbers, we divide by 4:
1,000 divided by 4 = 250.
We don't round to the nearest 100 for 250 because the question said to only round for the original numbers. But, if i am wrong somehow, 250 rounded is 300.

The table is completed as follows using the double-declining-balance method of depreciation:

1 $30,000 $0 $30,000 $12,000 $12,000 $18,000
2 $30,000 $12,000 $18,000 $7,200 $19,200 $10,800
3 $30,000 $19,200 $10,800 $4,320 $23,520 $6,480
The double-declining-balance approach is what?
The double-declining-balance method is one of the depreciation techniques in use, however it adds additional costs in the first years of an asset's life.
In this depreciation method, the straight-line rate, which is computed as the product of 100/estimated useful life multiplied by 2, is twice.
At the conclusion of each year, the leftover balance for the depreciation charge is adjusted using the double rate.
The difference between the closing balance from the previous year and the residual value is used to determine the depreciation charge for the most recent year.
Auto = $30,000
Estimated useful life = 5 years
Residual = $800
Depreciable amount = $30,000 - $800 = 29,200
Straight-line depreciation rate = 100/5 = 20%
Double-declining depreciation rate =20% x 2 = 40%
Depreciation Expense:
1st year = 30,000 x 40/100 = 12,000
2nd year = 18,000 x 40/100 = 7,200
3rd year = 10,800 x 40/100 = 4,320
4th year = 6,480 x 40/100 = 2,592
5th year = 3,888 x 40/100 = 1,555
