Which point is in the solution set of the system of inequalities
shown in the accompanying graph?
A. (0,4)
B. (2,4)
C. (-4,1)
D. (4,-1)
Answers
Answer: Option c.
Step-by-step explanation:
The dotted line means that the points in the line do not belong to the system, while the other line has all the points on the line.
Now, the point we are looking for must be a solution for both inequalities, so it must be in the region of the graph that is double shaded. (this would be the area at the left)
You now can take each point and see where it is located in the graph, if it is inside the double shaded area, then it is the correct answer.
Now, you will see that the only point that lies inside the double shaded area is the point (-4,1), so the correct option is c.
The point (-4, 1) is in the solution set of the system of inequalities.
An inequality shows the non equal comparison between two numbers or variables.
Given the inequalities as shown in the graph, the solution set of the inequalities is the point that lies on the dark shaded portion.
The dark shaded portion is the solution of the inequality.
From the graph the point (-4, 1) lies on the dark shaded portion.
Therefore the point (-4, 1) is in the solution set of the system of inequalities.

Suppose that f(x)=x^2 and g(x)=-2/3 x^2 which statement best compares the graph of g)x) with the graph of f(x)?
Answers
The graph of g(x) is the graph of f(x) stretched vertically and reflected over the axis.
The correct option is C.
We can compare the graphs of two functions f(x)=x² and g(x)=-2/3 x² by determining their vertices, domain, range, axis of symmetry, and shape of the graphs. The vertex of f(x)=x² is at the origin (0,0), which means that the parabola opens upward and is symmetrical around the y-axis.
The domain is all real numbers, and the range is y≥0. The axis of symmetry is the y-axis. On the other hand, the vertex of g(x)=-2/3 x² is also at the origin, and it opens downward. It is also symmetrical around the y-axis. The domain is all real numbers, and the range is y≤0.
The axis of symmetry is the y-axis, just like f(x).It is important to remember that g(x) is the negative of f(x), which indicates that g(x) is reflected across the x-axis. Furthermore, the stretch factor is 2/3, which makes the graph of g(x) flatter than the graph of f(x) and it is stretched vertically and reflects over x axis(option c).

A person accepts a position with a company at a salary of \( \$ 34,000 \) for the frat year, The person is guaranteed a raise of \( \$ 1850 \) per year for the first 6 years. Determine the person's to
Answers
The person's total salary over the first 6 years is $231,750.
To determine the person's total salary over the first 6 years, we need to calculate the sum of the salary for each year.
Given information:
- Initial salary: $34,000
- Annual raise: $1,850
- Number of years: 6
To calculate the total salary, we can use the arithmetic progression formula:
[ S = frac{n}{2} left(2a + (n - 1)dright) ]
Where:
- ( S ) is the sum of the salaries
- ( n ) is the number of terms (years)
- ( a ) is the first term (initial salary)
- ( d ) is the common difference (annual raise)
Substituting the given values, we have:
[ S = frac{6}{2} left(2(34000) + (6 - 1)(1850)right) ]
Simplifying the expression:
[ S = 3 left( 68000 + 5 times 1850 right) ]
[ S = 3 left( 68000 + 9250 right) ]
[ S = 3 times 77250 ]
[ S = 231750 ]
Therefore, the person's total salary over the first 6 years is $231,750.

Answers
It is not possible to use n = 10.
It is not possible to use n = 20.
It is possible to use n = 25.
1. The error probabilities for n = 10 are as follows:
- P-value: It is not possible to use n = 10 because there is no value of x which results in a p-value.
- Beta (0.3): B(0.3) > 0.1, which means the probability of failing to reject the null hypothesis (p = 0.1) when the true probability of a leak is actually 0.3 is too high.
Therefore, it is not possible to use n = 10.
2. The error probabilities for n = 20 are as follows:
- P-value: It is not possible to use n = 20 because it results in a beta error probability (B(0.3)) < 0.1, which means the probability of incorrectly rejecting the null hypothesis (p = 0.1) when the true probability of a leak is actually 0.3 is too low.
- Beta (0.3): B(0.3) > 0.1, which means the probability of failing to reject the null hypothesis (p = 0.1) when the true probability of a leak is actually 0.3 is too high.
Therefore, it is not possible to use n = 20.
3. The error probabilities for n = 25 are as follows:
- P-value: P(0.3) < 0.1, which means the probability of incorrectly rejecting the null hypothesis (p = 0.1) when the true probability of a leak is actually 0.3 is low enough to proceed with production.
- Beta (0.3): B(0.3) < 0.1, which means the probability of failing to reject the null hypothesis (p = 0.1) when the true probability of a leak is actually 0.3 is low enough to proceed with production.

True/False: The general solution to a third-order differential equation must contain three constants
Answers
True. The general solution to a third-order differential equation typically contains three arbitrary constants.
The general solution to a third-order differential equation must contain three constants. This is because the order of a differential equation refers to the highest derivative present in the equation. A third-order differential equation involves the third derivative of the unknown function.
When solving a differential equation, we typically find a general solution that encompasses all possible solutions to the equation. This general solution includes an arbitrary number of constants, depending on the order of the differential equation.
For a third-order differential equation, the general solution will contain three arbitrary constants. This is because each constant represents a degree of freedom in the solution, allowing us to accommodate a wide range of functions that satisfy the given differential equation.These constants can be determined by applying initial conditions or boundary conditions to the differential equation, which narrows down the solution to a particular function.
Therefore, when dealing with a third-order differential equation, it is expected that the general solution will contain three constants to account for the necessary degrees of freedom in constructing the solution.

determine if a triangle is a (unique triangle) or a (no triangle) or (more than one triangle)
Answers
To determine if a triangle is unique, not a triangle, or more than one triangle, we need to examine the given information about the triangle's side lengths. In a valid triangle, the sum of any two sides must be greater than the third side. Based on this concept, we can evaluate the possibilities.
If the sum of the lengths of the two shorter sides is greater than the length of the longest side, then a unique triangle can be formed. This is known as the Triangle Inequality Theorem. The unique triangle can be constructed by connecting the three given side lengths.
If the sum of the lengths of the two shorter sides is equal to the length of the longest side, then no triangle can be formed. This condition is known as a degenerate triangle or a straight line. In this case, the three sides are collinear and do not form a closed figure.
If the sum of the lengths of the two shorter sides is less than the length of the longest side, then it is not possible to form a triangle. The given side lengths do not satisfy the Triangle Inequality Theorem, and thus, no triangle can be constructed.
By applying the Triangle Inequality Theorem and comparing the side lengths, we can determine whether a unique triangle, no triangle, or more than one triangle can be formed based on the given information.
