Answer:
x=2 and x=-10 are the solutions that you should get by using the quadratic formula.
Does an X or y-axis scale have to always start at zero?.
No, X or y-axis scale does not have to always start at zero. In a line chart, it's OK to start the axis at a number other than zero
Define axis.A line that is used to take or mark measurements is known as an axis in mathematics. Two crucial axes of the coordinate plane are the x and y axes. A horizontal number line is the x-axis, while a vertical number line is the y-axis. The coordinate plane is created by the perpendicular intersection of these two axes.
Given,
No, X or y-axis scale does not have to always start at zero.
A line chart encodes data using location (x, y coordinates), whereas a bar chart represents data using length. In a line chart, it's OK to start the axis at a number other than zero despite many claims that they are always misleading since this minute difference influences how a reader utilizes the chart.

Zen Inc. manufactures two types of products, the G1 and the T1 model airplane. The manufacturing process consists of two principal departments: production and assembly. The production department has 58 skilled workers, each of whom works 7 hours per day. The assembly department has 25 workers, who also work 7-hour shifts. On an average, to produce a G1 model, Zen Inc. requires 3.5 labor hours for production and 2 labor hours for assembly. The T1 model requires 4 labor hours for production and 1.5 labor hours in assembly. The company anticipates selling at least 1.5 times as many T1 models as G1 models (this is the product mix). The company operates five days per week and makes a net profit of $130 on the G1 model, and $150 on the T1 model. Zen Inc. wants to determine how many of each model should be produced on a weekly basis to maximize net profit. If the numbers of G1 and T1 products produced each week are denoted as G and T respectively, the function that describes Zen, Inc.’s sales product mix for a week is?
Each model should be produced on a weekly basis to maximize net profit is $75,900.
What is Net profit?
In both business and accounting, net income or profit is an entity's revenue less cost of goods sold, costs, depreciation and amortisation, interest, and taxes for a certain accounting period.
As given,
Number of products sold:
T ≥ 1.5G
Maximize Profit Z = 150T + 130G
Labor Constraint:
Labor hours Available:
Production Department:
Number of labor hours available per day = 58 × 7 = 406
Number of days in a week = 5
Number of lobor ours available per week = 406 × 5 = 2030
Assembly Department:
Number of labor hours available per day = 25 × 7 = 175
Number of days in a week = 5
Number of labor hours available per week = 175 × 5 = 875.
Labor hours Required:
Labor hours required for G1 model:
Labor hours required at Production department = 3.5G
Labor hours required at assembly department = 2G
Labor hours required for T1 model:
Labor hours required at Production department = 4T
Labor hours required at Assembly department = 1.5T
Total labor hours required at Production department = 3.5G + 4T
Total labor hours required at Assembly department = 2G + 1.5T.
Constraint:
Labor hours required ≤ Labor hours Available.
Production department Labor constraint
3.5G + 4T ≤ 2030
Assembly department Labor constraint:
2G + 1.5T ≤ 875
The function:
Maximum Profit Z = 150T +130G
Constraint:
3.5G +4T ≤ 2030
2G + 1.5T ≤ 875
T ≥ 1.5G
Suppose that for example:
10.5G +12T = 6090
16G + 12T = 7000
Solve both equations simultaneously,
5.5G = 7000 - 6090
5.5G = 910
G = 910/5.5
G = 363
Since, T > G
Hence,
T = 363,
G = 165
Calculate Profit:
150T + 130G = 150 × 363 + 130 × 165
= 54450 + 21450
= 75900
Hence, each model should be produced on a weekly basis to maximize net profit is $75,900.

Qa.) State the contrapositive of the following implication. If G is a connected planar graph then G has at least one vertex of degree <= 5.
Qb.) Prove the contrapositive stated in part (a). Hint: use the fact that if G is a connected Planar graph , then e <= 3v-6.
Qc.) Use part (a) to show that every planar graph can be colored with 6 (or less) colors. Hint: Use a proof by Induction on the number of vertices G.
We assume that G is a connected planar graph with no vertex of degree <= 5. We will use e <= 3v - 6 to prove that G is not a planar graph. By handshaking lemma, we know that 2e = sum of degrees of all vertices. Let d be the maximum degree of G.
Qa. Contrapositive of an implication is a new implication formed by negating both the hypothesis and the conclusion.
The contrapositive of the implication "If G is a connected planar graph, then G has at least one vertex of degree <= 5" is "If G has no vertex of degree <= 5, then G is not a connected planar graph."
Qb. Proof: We assume that G is a connected planar graph with no vertex of degree <= 5.
We will use e <= 3v - 6 to prove that G is not a planar graph. By handshaking lemma, we know that 2e = sum of degrees of all vertices.
Let d be the maximum degree of G. Since G has no vertex of degree <= 5, then d >= 6.
Thus, the sum of degrees of all vertices in G is greater than or equal to 6v/2, which is equal to 3v.
Hence, 2e >= 3v.
Substituting this inequality in e <= 3v - 6, we get 2e >= 3e - 6, which implies that e >= 6.
Since e >= 6, it follows that G is not planar.
Qc. Proof: We use proof by induction on the number of vertices of G. For a graph with one vertex, the statement is trivially true.
For a graph with n > 1 vertices, assume that every planar graph with at most n - 1 vertices can be colored with 6 (or less) colors.
Let G be a planar graph with n vertices.
By part (a), there exists a vertex v of G with degree <= 5.
We remove v and all its edges from G to get a new graph G' with n - 1 vertices.
By the induction hypothesis, we can color G' with 6 (or less) colors.
We add back v and its edges to G.
Since v has degree <= 5, at most 5 colors are used on its adjacent vertices.
We use a new color for v.
Thus, G can be colored with 6 (or less) colors.
Therefore, by induction, the statement is true for all planar graphs.

I need help answering this question:
-9 ÷ +3
Answer:
-3
Step-by-step explanation:
-9 divided by +3 can be written as -9 divided by 3, because when you have a positive number, you don't have to write a plus sign in front of it. Next, we can just do 9/3 and then add the negative sign to the result to get our answer. 9 divided by 3 is equal to 3, and when you add the negative sign, you get -3.
Which line has a slope of 2/5?
Answer:
Line kinda flat, going up (from left to right) goes right through the 3 on the y-axis. Through the points (0,3) and (5,5) The third image.
Step-by-step explanation:
The slope of 2/5 means go UP2 and OVER5. Only one graph has a line the goes UP2 and OVER5.
One line actually goes down (from left to right), that has a negative slope. So that's not it.
The first image is positive slope, but if you look at the two points, you go UP5 and OVER2 so that is wrong also. That is the slope 5/2.
The last image has slope 2/7, bc you go UP2 OVER7 to get from one point to the next. It is wrong also.

which rule must be used to find the number of strings of four decimal digits that have exactly three digits that are 9s?
The product rule must be used to find the number of strings of four decimal digits, that have exactly three digits that are 9s.
What is product rule ?
The Product Rule says that the derivative of a product of two functions is the first function times the derivative of the second function plus the second function times the derivative of the first function.
To obtain the number of strings of 4 decimal digits that have exactly 3 digits that are 9s ; we use the product rule,
In first digit 1 possible way between 0 to 9
In second digit 1 possible way between 0 to 9
In third digit 1 possible way between 0 to 9
In fourth digit 9 possible ways between 0 to 9
That's mean 1 * 1* 1* 9* 4 = 36

Give an example of a matrix A and a vector b such that the solution set of Ax=b is a line in R3 that does not contain the origin.

\(AX = \left[\begin{array}{ccc}1&1&1\\1&2&3\\1&4&7\end{array}\right]\) \(\left[\begin{array}{ccc}x\\4\\2&\end{array}\right]\)
and b = \(\left[\begin{array}{ccc}6\\14\\30&\end{array}\right]\)
the augmented matrix is [A:B] = \(\left[\begin{array}{ccc}1&1&1\\1&2&3\\1&4&7\end{array}\right]\) \(\left[\begin{array}{ccc}6\\14\\30&\end{array}\right]\)
we shall reduced the augmented matrix [A;B] to echelon form by applying elementary row transformation only.
operating \(R_{2} , R_{2} - R_{1} , R_{3} ,R_{3} -R_{1}\)
\([A:B] = \left[\begin{array}{ccc}1&1&1\\0&1&2\\0&3&6\end{array}\right]\) \(\left[\begin{array}{ccc}6\\8\\24&\end{array}\right]\)
operating \(R_{3} , R_{3} - 3R_{2}\)
≈ \(\left[\begin{array}{ccc}1&1&1\\0&1&2\\0&0&0\end{array}\right]\) \(\left[\begin{array}{ccc}6\\8\\0&\end{array}\right]\)
which is the row echelon form of the matrix [A:B].
A matrix that has gone through the Gaussian end is supposed to be in column echelon form or, all the more appropriately, "decreased echelon form" or "line diminished echelon form." Such a matrix has the accompanying qualities:
1. Every one of the zero columns are at the lower part of the matrix
2. The main passage of each nonzero column after the first happens to one side of the main section of the past line.
3. The main passage in any nonzero column is 1.
4. All sections in the segment above and under a main 1 are zero.
One more typical meaning of echelon form just requires zeros beneath the main ones, while the above definition additionally requires them over the main ones.

if using the method of completing the square to solve the quadratic equation x2-9x-26=0, which number would have to be added to complete the square (pls quickkkk!!)
The numbers would have to be added to complete the square is x = \(\frac{9+\sqrt{185} }{2}\) and x = \(\frac{9-\sqrt{185} }{2}\)
The quadratic equation is
\(x^2\) - 9x - 26 = 0
Add both side of the equation by 26
\(x^2\) - 9x - 26 + 26 = 26
\(x^2\) - 9x = 26
\(x^2\) - 2(9/2)x = 26
Take the coefficient of x and take square of the term and add both side of the equation
\(x^2\) - 2(9/2)x + 81/4 = 81/4 + 26
Add the terms
\(x^2\) - 2(9/2)x + 81/4 = 185/4
Form the left side of the equation in the form of \((a-b)^2\)
Then the equation will be
\((x-\frac{9}{2} )^2\) = 185/4
x - 9/2 =± \(\frac{\sqrt{185} }{2}\)
x = \(\frac{\sqrt{185} }{2}\) + 9/2
x = \(\frac{9+\sqrt{185} }{2}\)
Then
x = - \(\frac{\sqrt{185} }{2}\) + 9/2
x = \(\frac{9-\sqrt{185} }{2}\)
Hence, the numbers would have to be added to complete the square is x = \(\frac{9+\sqrt{185} }{2}\) and x = \(\frac{9-\sqrt{185} }{2}\)
