The domain of the function (f(x))/(g(x)) is all real numbers except x = 7. In interval notation, the domain can be expressed as (-∞, 7) U (7, +∞). This means that any real number except 7 can be used as an input for the function.
To find the domain of the function (f(x))/(g(x)), we need to consider the restrictions on the variable x that would make the expression undefined. In this case, division by zero is undefined, so we need to determine the values of x that would make the denominator, x - 7, equal to zero.
Setting the denominator equal to zero:
x - 7 = 0
Solving for x:
x = 7
We find that x = 7 would make the denominator zero, which would result in division by zero and an undefined expression.
Therefore, the domain of the function (f(x))/(g(x)) is all real numbers except x = 7. This means that any real number can be used as an input for the function, except for x = 7. In interval notation, the domain can be expressed as (-∞, 7) U (7, +∞), indicating that x can take any value less than 7 or greater than 7, but it cannot equal 7.

the volume of a circular cylinder is $100$ cubic feet. if the radius of its base decreases by $10\%$ but the height increases by $10\%$, what is the volume of the new cylinder in cubic feet?
Answer:
100
Step-by-step explanation:
its impossable
The new volume of the cylinder is $100$ cubic feet.
Let the original radius and height of the cylinder be $r$ and $h$, respectively. Therefore, the original volume of the cylinder is given by $\pi r^2 h = 100$. After the radius decreases by $10%$ and the height increases by $10%$, the new radius and height become $0.9r$ and $1.1h$, respectively. The new volume of the cylinder can be calculated as $\pi (0.9r)^2 (1.1h) = 0.891\pi r^2 h$. Since $0.891\pi r^2 h = 100$, the new volume of the cylinder is $100$ cubic feet.
Therefore, the new volume of the cylinder is the same as the original volume, i.e., $100$ cubic fee

Adding and subtracting rational expressions, What is the difference? 2x+5/x^2-3x - 3x+5/x^3-9x - x+1/x^2-9?
After adding and subtracting the rational expressions , the simplified rational expression is 4x - 4/x² - 5/x³ + 9 .
We first simplify each expression inside the parentheses :
that means :
⇒ (2x + 5/x² -3x) = (2x - 3x + 5/x²) = (-x + 5/x²) ;
⇒ (3x + 5/x³ - 9x) = (-6x + 5/x³) ;
⇒ (x + 1/x² - 9) = (-9 + x + 1/x²) ;
Now we substitute these expressions into original equation/expression :
we get ; (-x + 5/x²) - (-6x + 5/x³) - (-9 + x + 1/x²)
Simplifying further ,
we get ;
⇒ -x + 5/x² + 6x - 5/x³ + 9 - x - 1/x² ;
On Combining the like terms, we get ;
⇒ 4x - 4/x² - 5/x³ + 9

To solve this expression, we can use the order of operations, also known as PEMDAS, which stands for Parentheses, Exponents, Multiplication and Division (performed left to right), and Addition and Subtraction (performed left to right).
Following this order, we first need to evaluate the exponent, which gives:
1000^3 = 1,000,000,000
Then, we can substitute this value back into the expression:
1000 + 1000^3 = 1000 + 1,000,000,000 = 1,000,000,000 + 1000 = 1,000,001,000

What is a permutation vs combination?Subsets of a set can be created in two different ways: combination and permutation. The subset's components can be listed in any order when combined. The components of the subset are listed in a permutation in a particular order.The various ways in which items from a set may be chosen, usually without replacement, to form subsets, are called permutations and combinations. When the order of the selection is a factor, this selection of subsets is referred to as a permutation; when it is not, it is referred to as a combination.The order of the outcomes is irrelevant when calculating the total outcomes of an event using combinations. We will use the formula nCr = n! / r! * (n - r)! to calculate combinations.C(6,2) = 6!/(4!2!) = 15.

true or false? a proportion is a type of ratio in which the numerator is part of the denominator and can be expressed as a percentage.
True, a proportion is a type of ratio in which the numerator is part of the denominator and can be expressed as a percentage.
A proportion is a mathematical relationship between two numbers, showing that one number is a part of the other or that they share a certain ratio. It compares two ratios and checks if they are equal. For example, if we have two ratios 1:2 and 2:4, these ratios are in proportion because they have the same relationship (1 is half of 2, and 2 is half of 4).
To express a proportion as a percentage, follow these steps:
Convert the ratio to a fraction: In our example, the ratio 1:2 can be converted to the fraction 1/2.
Divide the numerator by the denominator: In this case, we will divide 1 by 2, which equals 0.5.
Multiply the result by 100: Finally, multiply 0.5 by 100 to get the percentage, which is 50%.
So, the statement is true that a proportion is a type of ratio in which the numerator is part of the denominator and can be expressed as a percentage. This concept is essential in various mathematical and real-life applications, such as calculating discounts, tax rates, and percentages of various quantities.

Which of the following recursive formulas represents the same arithmetic sequence as the explicit formula an = 5+ (n-1)2?
Answer:
\(a_1 = 5\)
\(a_n = a_{n-1} + 2\)
Step-by-step explanation:
Given
\(a_n = 5 + (n - 1)2\)
Required
The equivalent recursive function
The general explicit function is:
\(a_n = a_1+ (n - 1)d\)
So, by comparison
\(a_1 = 5\)
\(d = 2\)
The recursion of an arithmetic sequence is:
\(a_n = a_{n-1} + d\)
Substitute 2 for d
\(a_n = a_{n-1} + 2\)

The single inequality y > |x + 2| is equivalent to which of the following systems?
Answers:

2.y > x + 2
y > –x – 2
3.y > x + 2
y < –x + 2
4.y > x + 2
y < –x – 2
The single inequality y > |x + 2| is equivalent to:
4. y > x + 2
y < –x – 2
What is an inequality?It should be noted that an inequality is simply used to show the relationship between the expressions that aren't equal.
The non-negative value of a real number x, regardless of its sign, is its absolute value or modulus | x |. For instance, 5 has an absolute value of 5, and 5 has a value of 5. One way to think about a number's absolute value is as its distance from zero on the real number line.
It should be noted that based on the information, the inequality is:
y > |x + 2|. This is the positive part of the modulus.
This is the same as y < –x – 2 when the signs are changed. This is the negative part of the modulus.
In conclusion, the correct option is 4.

Using the probability concept, it is found that:
The theoretical probability of choosing a card with the number 4 was of 0.20 = 20%.The experimental probability of choosing a card with the number 4 was of 0.24 = 24%.What is a probability?A probability is given by the number of desired outcomes divided by the number of total outcomes.
For an experimental probability, these number of outcomes are taken from previous trials. Researching the problem on the internet, it is found that 48 of the 200 trials resulted in the number 4 being chosen, hence:
pE = 48/200 = 0.24.

what is cos(x) and tan(x)? Explain your steps in complete sentences. (10 points)
Answer:
Cos x = \(\frac{base}{hypotenuse}=\frac{\sqrt{3} }{2}\)
Tan x = \(\frac{perpendicular}{base} = \frac{1}{\sqrt{3} }\)
Step-by-step explanation:
Sin x = \(\frac{perpendicular}{hypotenuse} = \frac{1}{2}\)
So, Perp = 1 and hyp = 2
Putting this in Pythagorean theorem to get the base
\(c^2 = a^2+b^2\)
\(a^2 = c^2-b^2\)
base ² = 4-1
base² = 3
Taking square root on both sides
Base = \(\sqrt{3}\)
Now
Cos x = \(\frac{base}{hypotenuse}=\frac{\sqrt{3} }{2}\)
Tan x = \(\frac{perpendicular}{base} = \frac{1}{\sqrt{3} }\)

A length is measure as 21cm correct to 2 significant figures. What is the upper bound and lower bound
The length in this instance is accurately measured at 21 cm to two significant figures.
1. Upper Bound:
The upper bound is the highest possible value that the measurement could have while still being correct to 2 significant figures.
In 21 cm, the last significant figure is 1.
The next possible value after 1 is 2.
So, half of the difference between 2 and 1 is 0.5.
Upper Bound = 21 + 0.5
= 21.5 cm
2. Lower Bound:
In 21 cm, the last significant figure is 1, and the next possible value after 1 is 2. So, half of the difference between 1 and 2 is 0.5.
Lower Bound = 21 - 0.5
