True. Rational functions are defined as the division of two polynomials. These functions are limited in their scope and, as a result, have specific properties. One such property is the existence of vertical asymptotes.
Vertical asymptotes occur when the denominator of a rational function approaches zero, resulting in a discontinuity in the graph of the function, or a point at which the function can approach but never reach. This creates a divide in the graph, resulting in two halves with a vertical line at the point where the denominator equals zero. This vertical line is the vertical asymptote of the rational function. In conclusion, all rational functions have vertical asymptotes due to their limited scope and specific properties.

what is rational number definition?
A rational number is a number that can be expressed as the ratio of two integers, where the denominator is not zero.
A normal number is a number that can be communicated as the proportion of two whole numbers, where the denominator isn't equivalent to nothing. This implies that a normal number can be written in the structure p/q, where p and q are numbers and q isn't equivalent to nothing.
For instance, 3/4, 7/2, and - 5/6 are instances of normal numbers. Be that as it may, numbers like pi (π) and the square foundation of 2 (√2) are not objective, since they can't be communicated as a proportion of two numbers.
Normal numbers are significant in math, as they structure a subset of the genuine numbers and can be utilized to address amounts in a wide range of settings, like portions, proportions, and probabilities. They are additionally utilized broadly in polynomial math, where they structure the reason for tackling conditions and controlling articulations.

Find the length of X
Answer:
[tex]x=3, x=\frac{17}{4}[/tex]
Step-by-step explanation:
The side opposite to the length of 20 is 7x - 11, whereas the side opposite to an unknown length is 4x - 2. To solve this unknown length, we are given 35 as the total length, so we can do 35-20 = 15, which is the opposite of the length of 4x-2.
Since we know the opposite sides of each side, we can set up these equations since we notice that the lengths are parallel based on what is diagrammed:

ABCD is a kite, So AC - DB and DE=EB Calculate the length of \overline{AC} AC to the nearest tenth of a centimeter.
Answer:
AC=9CM
Step-by-step explanation:
Since ABCD is a kite, we know that the two diagonals, AC and BD, intersect at right angles and that the two pairs of adjacent sides are congruent. Therefore, we have:
AC = BD and AB = BC = CD = DA
We also know that DE = EB, which means that triangle ADE is congruent to triangle BEC (by the side-side-side congruence rule), so we have:
AD = BC and AE = EC
AD=5cm and DC=4cm
Combining these equations, we have:
AC = AD + DC
AC=5cm+4cm=9cm

It is estimated that, during the past year, 27% of all adults visited a therapist and 43% of all adults used antidepressants. It is also estimated that 20% of all adults both visited a therapist and used a antidepressant during the past year.
(a)What is the probability that a randomly selected adult who visited a therapist during the past year also used antidepressants? Round your answer to the nearest hundredth.
(b)What is the probability that an adult visited a therapist during the past year, given that he or she used antidepressants? Round your answer to the nearest hundredth.
(a) To find the probability that a randomly selected adult who visited a therapist during the past year also used antidepressants, we use the formula:
P(A|B) = P(A and B) / P(B)
where A is the event that an adult used antidepressants, and B is the event that an adult visited a therapist. We are given:
P(A) = 0.43
P(B) = 0.27
P(A and B) = 0.20
Plugging these values into the formula, we get:
P(A|B) = 0.20 / 0.27 ≈ 0.74
Therefore, the probability that a randomly selected adult who visited a therapist during the past year also used antidepressants is approximately 0.74.
(b) To find the probability that an adult visited a therapist during the past year, given that he or she used antidepressants, we use Bayes' theorem:
P(B|A) = P(A|B) * P(B) / P(A)
where A and B are defined as before. We have already calculated P(A|B) and P(B), and we know:
P(A) = 0.43
Plugging these values into Bayes' theorem, we get:
P(B|A) = (0.74 * 0.27) / 0.43 ≈ 0.47
Therefore, the probability that an adult visited a therapist during the past year, given that he or she used antidepressants, is approximately 0.47.

what is 25 as a decimal?
The number 25 can be represented as a decimal by simply writing it as 25.0 or 25.00
The number 25 can be represented as a decimal by simply writing it as 25.0 or 25.00. This is because decimal notation is a way of writing numbers that uses a decimal point to separate the whole number part from the fractional part.
In this case, since 25 is a whole number and has no fractional part, we can represent it in decimal form by adding a decimal point and a zero or two zeros after it to indicate that there are no decimal places.
Alternatively, we can also represent 25 as a decimal by dividing it by 1, which does not change its value, and then expressing the quotient as a decimal. Since 25 divided by 1 equals 25, we can write 25 as a decimal by dividing 25 by 1 and writing the quotient as follows:
25 ÷ 1 = 25.000000... (with the decimal places repeating indefinitely)
However, in most cases, it is sufficient to represent 25 as 25.0 or 25.00, since these notations convey that the number has no fractional part.

A man claims to have extrasensory perception (ESP). As a test, a fair coin is flipped 30 times, and the man is asked to predict the outcome in advance. He gets 22 out of 30 correct. What is the probability that he would have done at least this well if he had no ESP?
the probability that the man would have done at least as well as 22 out of 30 correct predictions by chance alone is approximately 0.149 or 14.9%, which suggests that his ESP claim may not be supported by the coin flip test results alone.
To determine the probability that the man would have gotten at least 22 correct coin flip predictions if he had no ESP, we can use a statistical tool called a binomial distribution. Assuming the coin is fair, the probability of getting any single coin flip prediction correct is 0.5, since there are only two possible outcomes (heads or tails) and they are equally likely. We can use this probability to calculate the probability of getting exactly 22 correct predictions out of 30 coin flips, which is:
P(X = 22) = (30 choose 22) {multiply} 0.5^22 {multiply} 0.5{power}8 = 0.099
This means that the probability of getting exactly 22 correct predictions by chance is less than 10%. However, the question asks for the probability of getting at least 22 correct predictions, which includes the probabilities of getting 23, 24, 25, 26, 27, 28, 29, or 30 correct predictions as well.
To calculate this cumulative probability, we can add up the probabilities of getting each of these outcomes separately:
P(X >= 22) = P(X = 22) + P(X = 23) + ... + P(X = 30)
Using a binomial distribution table or calculator, we can find that this cumulative probability is approximately 0.149.
Therefore, the probability that the man would have done at least as well as 22 out of 30 correct predictions by chance alone is approximately 0.149 or 14.9%, which suggests that his ESP claim may not be supported by the coin flip test results alone.

The least common denominator is [tex](x^2-3x-4)/(x-4)(x+1) + (x^2-6x+8)/(x-4)(x-2) = 2/(x-4)(x+1)(x-2)[/tex]
Simply put, a rational expression is the product of two polynomials. Or to put it another way, it is a fraction using polynomials as the numerator and denominator.
Reasonable expressions resemble fractions with variable denominators (and often numerators too).
For rational expressions, any value can be entered with the exception of those that set the denominator to 0 (because division by 0 is an undefinable operation).
In other words, all real numbers other than those that make a rational expression's denominator zero are included in the domain of a rational expression.
[tex]x^2-3x-4 = (x-4)(x+1)\\x^2-6x+8 = (x-4)(x-2)[/tex]
The least common denominator is: [tex](x-4)(x+1)(x-2)[/tex]
To add these two rational expressions, we need to rewrite each of them with the LCD as the denominator:
[tex](x^2-3x-4)/(x-4)(x+1) = [(x-4)(x+1)]/(x-4)(x+1)(x-2) = 1/(x-2)\\(x^2-6x+8)/(x-4)(x-2) = [(x-4)(x-2)]/(x-4)(x+1)(x-2) = 1/(x+1)[/tex]
So the sum of the numerators is 1 + 1 = 2.
Therefore,[tex](x^2-3x-4)/(x-4)(x+1) + (x^2-6x+8)/(x-4)(x-2) = 2/(x-4)(x+1)(x-2)[/tex]

Time is a valuable commodity that we must use wisely. We measure it in seconds, minutes, hours, days, weeks, months, and years. It is important to be able to convert time units so that we can manage our schedule efficiently.
To convert minutes to hours, we need to divide the number of minutes by 60, which is the number of minutes in an hour. Therefore,
500 minutes ÷ 60 minutes/hour = 8.33 hours
However, this answer is in decimal form, which is not a typical way to represent time. We want to express it in hours and minutes.
To do so, we will use the fact that there are 60 minutes in an hour. Therefore, we can multiply the decimal part of the answer by 60 to get the remaining minutes.

A semicircle has radius 5.6cm. Work out the perimeter of the semicircle.
Answer:
28.79 cm.
Step-by-step explanation:
The perimeter of a semicircle is equal to the sum of the diameter (which is twice the radius) and half of the circumference of the circle.
The diameter of the semicircle is 2 × 5.6cm = 11.2cm.
The circumference of a full circle with radius 5.6cm is 2π × 5.6cm = 11.2π cm.
Therefore, the circumference of the semicircle is 1/2 of the circumference of the full circle, which is 1/2 × 11.2π cm = 5.6π cm.
The perimeter of the semicircle is the sum of the diameter and the circumference, which is:
11.2cm + 5.6π cm ≈ 28.79cm (rounded to two decimal places)
Therefore, the perimeter of the semicircle is approximately 28.79 cm.
Answer:
pi ( 5.6 ) + 11.2 or approximately 28.79291 cm
Step-by-step explanation:
The outside of the semicircle or the perimeter is 1/2 of the circumference and the length that closes the circle is the diameter.
Perimeter = 1/2 C + d
= 1/2 *pi*d + d
The diameter is 2 times the radius.
= 1/2 ( pi) * (2r) + 2r
= pi r + 2 r
= pi ( 5.6 ) + 11.2
Approximating pi, we get approximately 28.79291
