What is vertical asymptote?At the margins of the coordinate plane, the curve approaches lines known as asymptotes. When the denominator of such a rational function gets close to zero, vertical asymptotes happen. Since it would divide by zero, a rational function never traverse a vertical asymptote. A graph's vertical asymptote is a vertical line with the equation x=a, where the graph tends to positive or negative infinity as the inputs go closer to a.
For the given graph we can see that the vertical asymptotes are -1 and 3, and there is no horizontal asymptote.
In option A:
[tex]F(x) = \frac{x-2}{(x+1 )(x-3)}[/tex]
The horizontal asymptote is none.
The vertical asymptote is -1 and 3.
Hence, this is the correct option.
Option B:
[tex]F(x) = \frac{1}{(x-2)(x+1 )(x-3)}[/tex]
The horizontal asymptote is 0.
The vertical asymptote is 2, -1 , and 3.
Hence, option B is incorrect.
Option C:
[tex]F(x) = \frac{x-2}{(x-1 )(x+3)}[/tex]
The horizontal asymptote is none.
The vertical asymptote is 1 and -3.
Hence, option C is incorrect.
Hence, according to the graph the rational function represented in the graph is [tex]F(x) = \frac{x-2}{(x+1 )(x-3)}[/tex], and option A is correct answer.

three quantities, the results of measurements, are to be added. they are 2.0800, 2.677, and 1.67. what is their sum to the correct number of significant figures?
Answers
Sum to the correct number of significant figures is 6.43
Significant figures are the number of digits in a value, often a measurement, that contribute to the degree of accuracy of the value. We start counting significant figures at the first non-zero digit.
Significant figures are used to establish the number which is presented in the form of digits. These digits carry a meaningful representation of numbers. The term significant digits are also used often instead of figures. We can identify the number of significant digits by counting all the values starting from the 1st non-zero digit located on the left. For example, 12.45 has four significant digits.
Since the least precise measurement 1.67 is correct to only two decimal place.
2.0800
+ 2.677
+ 1.67
6.427
Therefore, the final result should be rounded off to 6.43 where Significant Figures: 3, Decimals: 2.
The arithmetic addition of given numbers to the correct number of significant figures is 6.43.

Interest of 3% a year of principal of 200,000 = 6000
monthly payment of 843 also includes a portion of amortization of the principal itself, which you can ignore cause the question only asked for the interest portion.
this is an unclear question cause it didn't say PER YEAR interest paid. you only need to remember interest% * principal = ANNUAL interest payment $. Then you can divide that over 12 months, which is 500$ per month.

an automobile manufacturer claims that their car has a 55.7 miles/gallon (mpg) rating. an independent testing firm has been contracted to test the mpg for this car. after testing 91 cars they found a mean mpg of 55.2 with a variance of 3.24 mpg. is there sufficient evidence at the 0.05 level that the cars underperform the manufacturer's mpg rating? state the null and alternative hypotheses for the above scenario.
Answers
For the given case the Null hypothesis is The mean mpg of the 91 cars tested is equal to the manufacturer's mpg rating of 55.7 and the Alternative hypothesis is The mean mpg of the 91 cars tested is less than the manufacturer's mpg rating of 55.7.
In order to determine whether the cars underperform the manufacturer's mpg rating, the independent testing firm would need to perform a hypothesis test. To do this, they would need to compare their sample mean of 55.2 mpg with the manufacturer's mpg rating of 55.7. They would also need to know the standard deviation of the sample, which is 3.24.
The independent testing firm would then calculate the z-score by subtracting the manufacturer's rating from the sample mean, and dividing it by the standard deviation. If the z-score is greater than the critical value for a 0.05 level of significance, then there is sufficient evidence to reject the null hypothesis.
In this case, the z-score is -1.51. Since the critical value for a 0.05 level of significance is 1.96, the z-score is less than the critical value. Therefore, there is not sufficient evidence to reject the null hypothesis, and we cannot conclude that the cars underperform the manufacturer's mpg rating.

mary divides a circle into sectors. the central angles of these sectors, measured in degrees, are all integers and they form an arithmetic sequence. what is the degree measure of the smallest possible sector angle?
Answers
The measure of the smallest possible sector angle possible is 8°.
Let [tex]$a_1$[/tex] be the first term of the arithmetic progression and [tex]$a_{12}$[/tex] be the last term of the arithmetic progression.
From the formula of the sum of an arithmetic progression, we have -
[tex]$12*\frac{a_1+a_{12}}{2}=360$[/tex]
simplifying we get,
[tex]$a_1 + a_{12} = 60$[/tex]
[tex]$a_{12}$[/tex] is the largest term of the progression and it can also be expressed as-
[tex]a_{12} = $a_1+11d$[/tex]
where d is a common difference.
Since each angle measure must be an integer, d should also be an integer.
[tex]$a_{12}-a_1=a_1+11d-a_1=11d$[/tex]
Since d is an integer, the difference between the first and last terms, 11d, must be divisible by 11.
Since the total difference should be less than 60, let's start checking multiples of 11 less than 60 for the total difference between [tex]$a_1$[/tex] and [tex]$a_{12}$[/tex].
Let us take the largest multiple because the maximum difference will give us the minimum value of the first term.
If the difference is 55, [tex]$a_1=\frac{60-55}{2}=2.5$[/tex], is not an integer.
If the difference is 44, [tex]$a_1=\frac{60-44}{2}= 8[/tex] . It satisfies the given conditions.
Hence, the measure of the smallest possible sector angle possible = 8°.

A towns population is expected to grow between 5% and 8% per year for the next 10yr. if the current population is 50,000, write an inequality for the expected population, p, next year.
Answers
Answer: An inequality for the expected population, p, next year can be written using the information provided. Since the population is expected to grow between 5% and 8% per year, we can represent that as a range of growth rates: 0.05 <= growth rate <= 0.08
To find the expected population next year, we can use the formula:
p = population * (1 + growth rate)
where "population" is the current population of 50,000 and "growth rate" is the percentage increase. Since the growth rate is expected to be between 0.05 and 0.08, we can write the inequality as:
50,000 * (1 + 0.05) <= p <= 50,000 * (1 + 0.08)
This inequality represents the expected range of population next year, with the lower bound being the population if it grows by 5% and the upper bound being the population if it grows by 8%.
Simplifying the inequality:
52,500 <= p <= 54,000
So the expected population next year, p, is between 52,500 and 54,000.

In bags of Happy Trail Mix, the number of raisins is skewed left with a mean of 33. 6 and a standard deviation of 8. 4, while in bags of a generic trail mix, the number of raisins is skewed right with a mean of 28. 8 and a standard deviation of 12. 7. What is the probability in a sample of 17 randomly selected Happy Trail Mix bags and a sample of 17 randomly selected generic bags that the mean number of raisins in the Happy Trail Mix is more than the mean number of raisins in the generic mix?
Answers
The probability that the mean number of raisins in the Happy Trail Mix is more than the mean number of raisins in the generic mix is 9.7%.
To solve this problem, we need to use the central limit theorem, which states that the distribution of the sample means approaches a normal distribution as the sample size increases. With a sample size of 17, we can approximate the distribution of the sample means as normal.
Let's call the mean of the Happy Trail Mix sample x and the mean of the generic mix sample y.
Using the formula for the mean of a normal distribution, we can find the mean of x and y:
μx = μ = 33.6
μy = μ = 28.8
Using the formula for the standard deviation of the sample mean, we can find the standard deviation of x and y:
σx = σ/√n = 8.4/√17 = 2.04
σy = σ/√n = 12.7/√17 = 3.08
Now that we have the mean and standard deviation of x and y, we can use a normal distribution calculator or a z-score table to find the probability that x > y.
The z-score is given by:
z = (x - y - μ)/σ = (33.6 - 28.8)/(√(2.04^2 + 3.08^2)) = 1.30
Using a standard normal table, we find that the probability of a z-score being greater than 1.30 is 0.097, or 9.7%.

Assume the coordinates of a triangle are -

parallelogram has sides of lengths 35 inches and 75 inches. One angle has measure of140°. Find the length of each diagonal.
Answers
The length of diagonal of a parallelogram is 2546 inches.
What is a parallelogram?A quadrilateral with equal pairs of opposing sides and angles is referred to as a parallelogram. It has a pair of opposing sides that are parallel to one another. The inner angles are supplementary in nature, meaning that the sum of them equals 180 degrees. A parallelogram's diagonals are bisected by one another, or divided into two equal portions. A parallelogram's internal angles add up to 360 degrees.
The diagonals of parallelogram are given by:
x = √(a^2 + b^2 – 2ab cos A) = √(a^2 + b^2 + 2ab cos B)
Given the two sides are 35 and 75 inches.
We also know that the adjacent angles of parallelogram are supplementary:
∠A + ∠B = 180
140 + ∠B = 180
∠B = 40
Substitute the value of sides and angle in the equation:
x = √(a^2 + b^2 – 2ab cos A) = √(a^2 + b^2 + 2ab cos B)
x = √((35)^2 + (72)^2 + 2(35)(72) cos 140)
x = 1225 + 5184 + (5040)(-0.766)
x = 1225 + 5184 - 3860
x = 2546 inches
Hence, the length of diagonal is 2546 inches.

Answers
To find the balance of the account after 3 years, we can use the formula for compound interest:
A = P(1 + r/n)^(nt)
Where A is the final amount, P is the initial principal, r is the interest rate, n is the number of times the interest is compounded per year, and t is the number of years.
In this case, the initial principal is $2,600, the interest rate is 4.2% (expressed as a decimal), the number of times the interest is compounded per year is 12 (monthly), and the number of years is 3.
So, we can plug these values into the formula:
A = 2600(1 + 0.042/12)^(12*3)
A = 2600(1.0035)^36
A = 2600 * 3.876
