The situation in which the value of the solution may be made infinitely large in a maximisation linear programming problem or infinitely small in a minimisation problem without violating any of the constraints is known as an unbounded solution
What is Linear Programming?
When a linear function is exposed to various constraints, it is maximised or reduced using the mathematical modelling technique known as linear programming.
Let's briefly define some situations
Infiniteness and semi-optimality, does not comply with what the situation exposes.
If there isn't a solution that satisfies all the requirements, the problem is said to be infeasible. As a result, this choice is not.
If the objective function can be improved indefinitely without going against the constraints and limits, then the problem is unbounded, and this is the right response.
The situation in which the value of the solution may be made infinitely large in a maximisation linear programming problem is known as an unbounded solution

The ratio of roses to lilles in a garden is 3 to 2 what percentage of the gardens flowers are roses
Answer:
To find the percentage of roses in the garden, we first need to determine the total number of flowers in the garden. We can do this by adding the number of roses and lilies, and then multiplying that number by the ratio of roses to lilies. For example, if there are 3 roses and 2 lilies in the garden, the total number of flowers would be 5 (3 + 2 = 5). To determine the percentage of roses, we would then divide the number of roses by the total number of flowers, and multiply by 100. In this case, the percentage of roses would be 60% (3 / 5 * 100 = 60).

-4x² + x - 7 = y
2x + 8 = -y ( solve by elimination )
A technique for solving an equation system is elimination.
What is elimination method ?Elimination is a method of solving a system of equations. In elimination, the goal is to eliminate one of the variables by adding and subtracting equations in order to create an equation with a single variable. This equation can then be solved for the single variable. For example, given the system of equations 2x + 8 = -y and 4x² + x - 7 = y, we can use elimination to solve for the variables x and y. To do this, we first need to multiply the first equation by -4, giving us -8x - 32 = 4y. We then add the two equations together, which gives us 4x² + 9x - 39 = 0. This equation can be solved using the quadratic formula, which gives us x = -3. To solve for y, we can plug x = -3 into either of the original equations. Plugging this value into the first equation gives us 2(-3) + 8 = -y, which simplifies to -6 + 8 = -y, and therefore y = 2. This method of using elimination to solve a system of equations can be used to solve any system of equations with two variables.2x + 8 = -y
-4x² + x - 7 = -y
Subtracting 2x + 8 from both sides:
-4x² - x + 15 = 0
(4x - 5)(x + 3) = 0
4x - 5 = 0
x = 5/4

29. The school that Lilly goes to is selling tickets to a drama performance. On the first day of ticket sales the
school sold 3 adult tickets and 1 child ticket for a total of $38. The school took in $104 on the second
day by selling 6 adult tickets and 4 child tickets. Find the price of an adult ticket and the price of a child
ticket.
Answer:
the price of an adult ticket is $8, and the price of a child ticket is $14.
Step-by-step explanation:
To find the price of an adult ticket and the price of a child ticket, we need to set up a system of equations. Let "A" represent the price of an adult ticket and "C" represent the price of a child ticket.
On the first day, the school sold 3 adult tickets and 1 child ticket for a total of $38, so we can set up the following equation to represent this information:
3A + C = 38
On the second day, the school took in $104 by selling 6 adult tickets and 4 child tickets, so we can set up the following equation to represent this information:
6A + 4C = 104
Now that we have our two equations, we can solve for the values of A and C. We can use the elimination method to solve this system of equations. To do this, we need to multiply one of the equations by a constant so that one of the variables has the same coefficient in both equations. We'll multiply the first equation by 2:
6A + 2C = 76
We can then subtract this equation from the second equation to eliminate the C term:
6A + 4C - 6A - 2C = 104 - 76
This simplifies to:
0A + 2C = 28
Dividing both sides by 2, we get:
C = 14
We can now substitute this value for C in one of our original equations and solve for A. We'll use the first equation:
3A + 14 = 38
Subtracting 14 from both sides, we get:
3A = 24
Dividing both sides by 3, we get:
A = 8
Therefore, the price of an adult ticket is $8, and the price of a child ticket is $14.

What is Domain and Range of a function ?A function's domain and range are its constituent parts. Range, Domain, and Function. A is the domain and B is the co-domain if a function f: A B exists that maps every element of A to an element in B. 'b', where (a,b) R, provides the representation of an element 'a' under a relation R. The collection of photos is the function's range. In general, a function's domain and range are denoted as follows:
Domain(f) = {x ∈ R} and range(f)={f(x) : x ∈ domain(f)}
"All the values" that are input into a function are referred to as the domain of a function. The collection of all potential inputs for a function is its domain. Think of this box as the f(x) = 2x function. The domain is only the collection of natural numbers when the input values are x = 1,2,3,4,..., and the values that are returned are referred to as the range. However, f(x) = 2x is often defined for all real values of x, and as a result, its domain is the set of all real numbers, which is represented by (-∞, ∞). The general formulae for determining the domain of various types of functions are listed below. The set of all real numbers, or R, is used here.
The collection of all a function's outputs is its range. Example: Let's have a look at the function f: A->B, where f(x) = 2x and A and B each represent a "collection of natural numbers." The domain in this instance is A, and the co-domain is B. The range then appears as the function's output. Set of even natural numbers is the range. The components of the co-domain that are mapped are known as the pictures, while the elements of the domain are known as pre-images. The set of all pictures of the domain's elements in this case serves as the function's range, as does the set of all of its outputs.
Domain of the function x = {-1,2,4}
The function is f(x) = 5 - 10x
range when x = -1
f(x) = 5 - 10*(-1) = 15

False. All economists do not believe that predatory pricing is a profitable business strategy.
What does "predatory pricing" mean?
A dominant company will often use predatory pricing as a deliberate strategy to drive out rivals by setting exceptionally cheap prices or supplying products for less than the company would otherwise have to spend on manufacturing (often equated for practical purposes with average variable costs).
Predatory pricing, sometimes referred to as undercutting, is a pricing strategy in which a good or service is offered at an extremely low cost with the goal of driving out rivals or establishing barriers to entry for potential new competitors.
If a competitor was selling a TV for $100 and you were offering the same TV for $80, you would be using predatory pricing.

Surface area of any figure is the area that the outer surface of any figure covers.
If we look at the different figures we find that these figures if placed somewhere or if we need to cover the figures with some kind of material then in order to find the the dimensions of the material we will need to find out the area that the overall surface of the figure will cover. This will reduce the time and complication of the calculations of every part of the shape. For example, If there is a need to find the surface area of the cylinder then we use the formula for its curved surface area as
S = 2πrh where r is the radius and h is the height of cylinder
Also, the total surface area will be expressed as

coffee is draining from a conical filter into a cylindrical coffeepot at the rate of 10 in3/min. (a) how fast is the level in the pot rising when the coffee in the cone is 5 in deep?
The level in the pot rising when the coffee in the cone is 5 in deep is 0.35 in/min.
Here the variables are the height of the coffee in the filter hf , the radius of the top of the coffee in the filter rf , and the height of the coffee in the pot hp:
We allowed Vp to represent the volume of coffee in the pot. We are interested in the instant when
hf = 5 in and dVp/dt = 10 in³/min.
The question is dhp/dt =? when dVp/dt = 10 in³/min and hf = 5 in
We need to relate hp to the other variables. In the pot (idealized as a cylinder), we have the volume Vp as Vp = π(3)²hp = 9πhp in³(since the volume of a cylinder of radius r and height h is V = πr²h).
Differentiation of Vp with respect to time gives dVp/dt = 9πhp/dt or
dhp/dt = (1/9π).(dVp/dt)
When dVp/dt = 10 in³/min and hf = 5 in, we have
dhp/ dt = 1/9π(10)
= 10/9π in/min
dhp/ dt ≈ 0.35 in/min (notice that the answer here is independent of hf ).
Hence, the level in the pot rising when the coffee in the cone is 5 in deep is 0.35 in/min.

What is a dependent variable?
In mathematical modelling, statistical modelling, and experimental sciences, there are dependent and independent variables. Dependent variables get their name because, during an experiment, one‘s values are examined under the assumption as well as demand that they are dependent on the value of another variable due to some law or rule (for example, a mathematical function). In the context of the experiment in question, independent variables are those that are not thought to be depending on other variables. Time, space, specific gravity, mass, fluid flow rate and previous values of certain observed value of interest (such as the size of the human population) are examples of common independent variables that can be used to forecast future value systems (the dependent variable).
The outcome of this hypothesis is the dependent variable.
Hence, the dependent variable in this hypothesis is test performance.
