Answers
The solution set of the inequality x ≥ - 4 using set builder notation and interval notation is {x | x ∈ Z, - 4 ≤ x ≤ ∞ } and [ - 4, ∞ ) respectively.
An inequality in mathematics is a relation that compares two numbers or other mathematical expressions in an unequal way.
A set can be represented by its elements or the properties that each of its members must meet can be described using set-builder notation.
Interval Notation: A set of real numbers known as an interval contains all real numbers that fall inside any two of the set's numbers.
Consider the inequality,
x ≥ - 4
In the number line, the value of x is equal to and greater than - 4 increasing to infinity.
Therefore,
The solution set using the set builder notation is:
{x | x ∈ Z, - 4 ≤ x ≤ ∞ }
The solution set of the inequality using the interval notation is:
[ - 4, ∞ )

The unit cost, in dollars, to produce bins of cat food is $18 and the fixed cost is $30000. The price-demandfunction, in dollars per bin, is p(x) = 568 - 2xFind the cost function.C(x) =Find the revenue function.R(x) = Find the profit function.P(x) = 568 – 2xAt what quantity is the smallest break-even point?
Answers
The smallest breakeven point attains at 75.
A formula or equation that describes the behavior of specific sources of income when it is plotted on a graph is called a revenue function.
The cost function calculates the lowest cost of producing a specific level of output at some fixed factor prices.
A relationship that demonstrates the difference that results from subtracting the cost function from the revenue function is called a profit function.
Here, the Price/Demand Function is presented as
P(x) = 568 - 2x
Which means that when there is a demand for x units of cat food, the price will be set at 568 - x for each unit.
Let's now consider the revenue resulting from this demand, or x units.
Revenue = Demand * Price per unit
R(x) = x * (568-2x)
= 568x – 〖2x〗^2
Now let us Evaluate the Cost Function
Cost = Variable cost + Fixed Cost
Variable cost = cost per unit * number of units
= 18*x
= 318
Fixed Cost = 30000 as given in the problem.
Hence
Cost Function C(x) = 18x + 30000
Now let’s find the Profit Function
Profit = Revenue - Cost
P(x) = R(x) - C(x)
568x - 〖2x〗^2 – (18x + 30000)
568x -〖 2x〗^2 – 18x + 30000
-〖 2x〗^2 + 550x - 30000
Finding the quantity at which we reach break-even point is the next step.
At break-even point, we understand this Profit = 0
Hence P(x) = 0
-〖 2x〗^2 - 550x + 30000 = 0
Dividing both sides by -2 we get
X2 – 275x + 15000 = 0
Now we have to find the factors of 15000 whose sum is 275.
Now we have to solve the above quadratic equation using splitting the middle term method.
X2 – 275x + 15000 = 0
X2 – 200x - 75x + 15000 =0
X(x-200) - 75 (x-200) = 0
(x-75) (x-200) = 0
Either (x - 75) = 0 or (x-200) = 0, therefore
(x-75) = 0 = x =75
(x-200) = 0 x =200
Smallest of which is 75.
As a result, 75 units are required to reach the break-even point.

We need to determine a few characteristics of the following linear equation:
[tex]y-5=-\frac{1}{2}(x-2)[/tex]The first step we need to take is to isolate the "y" variable on the left side.
[tex]\begin{gathered} y=\frac{-1}{2}(x-2)+5 \\ y=\frac{-1}{2}\cdot x+1+5 \\ y=\frac{-1}{2}\cdot x+6 \end{gathered}[/tex]Now we need to analyze this function and provide the necessary characteristics.
First is the Domain. The Domain of a function is the group of all numbers that can be used as an input (x), in this case the Domain is the whole Real group.
Second is the Range, which is the group of numbers that can be the output of the function (y), for this case we also have the whole Real group as Range.
Then we need to find the "Zero". Which is the value at which the function crosses the x-axis, to calculate it we must make "y=0" and solve for x.
[tex]\begin{gathered} 0=\frac{-x}{2}+6 \\ \frac{x}{2}=6 \\ x=12 \end{gathered}[/tex]The zero is equal to 12.
The slope of the function is the number multiplying "x", in this case it is -1/2.
The slope is negative, decrescent.
To find the value of f(8), we need to replace x by 8 and solve for y.
[tex]\begin{gathered} f(8)=\frac{-8}{2}+6 \\ f(8)=-4+6=2 \end{gathered}[/tex]The value of f(8) = 2.
To determine the value of x where f(x) is equal to 5, we need to replace f(x) by 5 and solve for x.
[tex]\begin{gathered} 5=\frac{-x}{2}+6 \\ \frac{-x}{2}=5-6 \\ \frac{-x}{2}=-1 \\ -x=-2 \\ x=2 \end{gathered}[/tex]The value of x for which f(x) is equal to 5, is 2.
Now we need to graph the equation, for that we have to use two of the points we found before, we will use (8, 2) and (2,5). We need to mark these points at the coordinate plane and draw a line between them:

We have,
Two equations:

9y + 3x = 15 ______(2)
From (1) we get,
3x = 10 - 5y
x = (10 - 5y) / 3 ______(3)

4y = 5
y = 5/4
Putting y = 5/4 in (3) we get,
x = (10 - 5 x 5/4) / 3
x = (10 - 25/4) / 3

4 × logx -(2 × logv + 3 × logy)
Answers
Simplifying the given logarithmic equation, the expression is obtained as log([tex]\frac{x^{4} }{v^{2} y^{3} }[/tex]).
The objective is to find the resultant expression for 4 × logx -(2 × logv + 3 × logy)
According to logarithmic results,
The product of an integer constant and a logarithm term of a number is equivalent to the logarithm of the number raised to the power of the particular integer constant.
That is, b × log(a) = log([tex]a^{b}[/tex])
Hence, 4 × log(x) = log([tex]x^{4}[/tex]),
2 × log(v) = log([tex]v^{2}[/tex])
and, 3 × log(y) = log([tex]y^{3}[/tex])
So, the equation can be rewritten as log([tex]x^{4}[/tex]) - (log([tex]v^{2}[/tex]) + log([tex]y^{3}[/tex]))
The sum of the logarithms of two numbers is equivalent to the logarithm of their product.
That is, log(a) + log(b) = log(a×b)
Hence, log([tex]v^{2}[/tex]) + log([tex]y^{3}[/tex]) = log([tex]v^{2}[/tex][tex]y^{3}[/tex])
So, the equation can be rewritten as log([tex]x^{4}[/tex]) - log([tex]v^{2}[/tex][tex]y^{3}[/tex])
The difference in the logarithms of two numbers is equivalent to the logarithm of their fraction.
That is, log(a) - log(b) = log(a÷b)
Hence, log([tex]x^{4}[/tex]) - log([tex]v^{2}[/tex][tex]y^{3}[/tex]) = log([tex]\frac{x^{4} }{v^{2} y^{3} }[/tex])

He following cards are dealt to three people at random, so that everyone gets the same number of cards. what is the probability that everyone gets a red card?
Answers
The probability that everyone will get a red card is 0.5.
What probability exactly is?Probability is a branch of mathematics that deals with numerical representations of the probability that an event will happen or that a statement is true.The probability of an event is a number between 0 and 1, with 0 roughly denoting impossibility and 1 denoting certainty.The probability is the likelihood that something will happen, to put it simply.The likelihood or likelihood of various outcomes can be discussed when we don't know how an event will turn out.The study of events that fit into a probability distribution is known as statistics.So, the probability that everyone gets a red card:
Probability formula: P(E) = Favourable events/Total number of eventsAs cards are distributed to 3 people, divide both favorable events and total events by 3.Then,
P(E) = Favourable events/Total number of eventsP(E) = (26/3)/(52/3)P(E) = 26/3 × 3/52P(E) = 26/52P(E) = 0.5Therefore, the probability that everyone will get a red card is 0.5.
