How can I do this with the function (x+2)/x-3
Create a rational function with a linear binomial in both the numerator and denominator.
Part 1. Graph your function using technology. Include the horizontal and vertical asymptotes and the x- and y-intercepts on your graph. Label the asymptotes and intercepts.
Part 2. Show all work to identify the vertical asymptote, the x-intercepts, and the y-intercept.
Answers
[tex]f(x) = \frac{x+2}{x-3} [/tex]
Part 1
The horizontal asymptote is obtained by either long division or synthetic division. It may be obtained also as
[tex]f(x)= \frac{x-3+5}{x-3} = \frac{x-3}{x-3} + \frac{5}{x-3} =1+ \frac{5}{x-3} [/tex]
Therefore the horizontal asymptote is
y = 1.
The vertical asymptote occurs when the denominator is zero because the function becomes undefined. Set x-3 = 0 to obtain
x = 3.
Therefore a vertical asymptote occurs at x = 3.
The x-intercept occurs when f(x) = y = 0. Set f(x)=0 to obtain
[tex] \frac{x+2}{x-3} =0[/tex]
For x≠3, obtain
x+2=0 => x = -2
The x-intercept is x = -2.
The y-intercept occurs when x=0. Set x=0 in f(x) to obtain
[tex]f(0)= \frac{0+2}{0-3} =- \frac{2}{3} [/tex]
The y-intercept is
y = -2/3
Part 2
The graph of the function is shown below. It identifies the horizontal and vertical asymptotes, the x-intercept, and the y-intercept.

Answers
The length of the rectangular parking lot is 130 meters.
What are the area and perimeter of a rectangle?The area of a rectangle is the product of its length and width.
The perimeter of a rectangle is the sum of the lengths of all the sides.
Given, The length of a rectangular parking lot is 10 meters less than twice it's width.
Assuming the width of the rectangle is x meters, therefore length would be
(2x - 10) meters and the perimeter is 400 meters.
We know the perimeter of a rectangle is 2(length + width).
∴ 2( x + 2x - 10) = 400.
2(3x - 10) = 400.
6x - 20 = 400.

Tiffany put a $1550 item on layaway by making a 20% down payment and agreeing to pay $120 a month. How many months sooner would she pay off the item if she increased her monthly payment to $180?
A. 18 months sooner
B. 11 months sooner
C. 4 months sooner
D 7 months sooner
Answers
1550*0.8=1240
1240/120 = approximately 11 months to pay off
1240/180=approximately 7 months to pay off
11-7 =4
so it would be paid off 4 months sooner, so C is the answer
Option: C is the correct answer.
C. 4 months sooner.
Step-by-step explanation:Total amount of the item is: $ 1550
Also, Tiffany paid 20% of the amount by down payment.
Hence, the amount left to pay after the down payment is:80% of total amount.
i.e. 0.80 of total amount.
= 0.80×1550
= $ 1240
Now the number of month it will take if she pay $ 120 a month is:
[tex]=\dfrac{1240}{120}=10.3333[/tex]
which is approximately equal to 11 months.
Similarly, the number of month it will take if she pay $ 180 a month is:
[tex]=\dfrac{1240}{180}=6.8889[/tex]
which is approximately equal to 7 months.
Hence, the number of months sooner she will pay off is:
11-7=4 months.

What is the formula for a finite geometric series and how can you use it in a practical situation?
Answers
Call r the ratio, An the nth term and An+1 the next term to n, then:
An+1 / An = r
For example, the geometric series, 1, 3, 9, 27, 81, ..
You can verify that
3 = 1* 3
9 = 3 * 3
27 = 9 * 3
81 = 27 * 3
So, the formula is An+1 = An * r, so if you know the first term you can find any other term.
For example, Find the fith term of a geometric series where the first term is 5 and the second term is 25.
r = secont term / first term = 25 / 5 = 5
=> Fifth term = First term * r * r * r * r = First term * r^4 = 25 * 5^4 = 15,625
From this you can also see this valid formula:
An = A1 * r^ (n-1).
So now you have two equivalent formulas:
An+1 = An * r, which is called recursive formula, and
An = A1 * r ^ (n-1), which is called explicit formula

The second mixture has 4 ounces of Sumatra and 12 ounces of Celebes Kalossi, and costs $21. How much does one ounce of Sumatra and one ounce of Celebes Kalossi cost?
Answers
12*x + 4*y=15
4*x + 12*y = 21
Now, solve it. For instance (there are many ways):
Multiply the second equation by (-3):
12*x + 4*y=15
-12*x -36*y = -63
Sum them up (x cancel out. That's why we multiply by -3)
-32y=-48, y = 48/32=6/4=3/2
y = 3/2 and x = go to any equation. Say the second again:
4*x + 12*y = 21
4x + 12*3/2 =21 ----> 4x + 18=21, 4x = 3, x = 3/4.
So cost of Sumatra $ 3/2 per oz, or $ 1.50
Cost of Celebes Kalossi (what a name!) $ 3/4 per oz = $ 0.75 per oz
Let's check it with the first equation:
12*0.75+4*1.5 = 15!

Choice #1: Describe each of the following properties of the graph of the cosine function, f(theta) = cos(theta), and relate the property to the unit circle definition of cosine. Amplitude Period Domain Range x-intercepts
Answers
The Amplitude is the maximum distance from 0 the function can be. In the case of [tex]cos(\theta)[/tex] that maximum distance is 1, because the unit circle has a radius of 1 and is centered at the origin, so the x value of a point on the circle can't be greater than 1.
Period = [tex]2\pi[/tex]
The period is the distance required for the function to complete one cycle. It takes [tex]2\pi[/tex] radians to make a full round of the unit circle, and after that [tex]cos(\theta)[/tex] repeats, so it is the period.
Domain = [tex]\mathbb{R}[/tex]
When the function is given an angle it radians, it goes that distance around the unit circle, and then gives the x value of the point on the circle at that distance. There is no [tex]\theta[/tex] that would cause this function to be undefined, so it's domains is [tex]\mathbb{R}[/tex].
Range = [tex]\{\theta \: | \: -1 \leq \theta \leq 1 \}[/tex]
The unit circle has a radius of 1 and is located at the origin so the x value of any point on the unit circle has to be between -1 and 1.
X-Intercepts: [tex]\frac{n\pi}{2} \:\: where\: n\: is \:any \:odd \:integer[/tex]
X-intercepts occur where a function evaluates to 0. For [tex]cos(\theta)[/tex] this occurs at odd multiples of [tex]\frac{\pi}{2}[/tex], as these are locations on the unit circle where the x value of the corresponding point on the circle is 0.
The graph of the cosine function, f(theta) = cos(theta), has properties such as amplitude, period, domain, range, and x-intercepts, and these properties can be related to the unit circle definition of cosine.
Explanation:The graph of the cosine function, f(theta) = cos(theta), has several properties:
Amplitude: The amplitude of the cosine function is 1, which means that the graph oscillates between a maximum value of 1 and a minimum value of -1.Period: The period of the cosine function is 2π, which means that the graph repeats itself every 2π units of theta.Domain: The domain of the cosine function is all real numbers, as there are no restrictions on the values of theta for which the cosine function is defined.Range: The range of the cosine function is the interval [-1, 1], as the values of the cosine function range from -1 to 1.X-intercepts: The x-intercepts of the cosine function occur when the value of theta is equal to π/2 + nπ, where n is an integer. In the unit circle, these x-intercepts correspond to the points where the terminal side of theta intersects the x-axis.These properties can be related to the unit circle definition of cosine. The amplitude corresponds to the distance from the origin to the maximum or minimum value of cosine on the unit circle. The period corresponds to the distance traveled along the unit circle to complete one cycle of the cosine function. The x-intercepts of the cosine function correspond to the angles at which the terminal side of theta intersects the x-axis on the unit circle.

The main cables of a suspension bridge are ideally parabolic. the cables over a bridge that is 400 feet logn are attached to towers that 100 feet tall. the lower point of the cable is 40 feet abouve the bdrige. find the equation that can be used to model the cables.
Answers
Let the vertex be on the y axis, exactly, at the point (0, 40)
Another point of this parabola is (200, 100), as can be checked from the figure.
The vertex form of the equation of a parabola is :
[tex]y=a(x-h)^{2}+k [/tex], where (h, k) is the vertex of the parabola,
replacing (h, k) with (0, 40), we have:
[tex]y=ax^{2}+40[/tex]
to find a, we substitute (x, y) with (200, 100):
[tex]100=a200^{2}+40[/tex]
40,000a=60
a=60/40,000=3/(2,000)
So, the equation of the parabola is [tex]y= \frac{3}{2000} x^{2}+40[/tex]
The equation to model the suspension cables of a bridge, where the lowest point of the cable is 40 feet above the bridge, and the towers are 100 feet tall and 200 feet from the center, is y = -0.0015x^2 + 60.
Explanation:To find the equation that models the suspension cable of a bridge, we use the properties of a parabolic shape. Since the cable is attached to towers that are 100 feet tall and the lowest point of the cable is 40 feet above the bridge, we know the vertex of the parabola is 60 feet (100 - 40) below the top of the towers.
Let's define the coordinate system with the origin at the lowest point of the cable. Then the towers are at (-200, 60) and (200, 60) because the bridge is 400 feet long, so each tower is 200 feet horizontally from the center. The parabolic equation takes the general form y = ax^2 + bx + c. Because the vertex is at (0, 60), c = 60.
Using the points (-200, 60), we can substitute into the parabolic equation and write a system to solve for a and b. Since the parabola is symmetric, b = 0. The system becomes 60 = a(-200)^2 + 60, which simplifies to a = -60/40000.
Thus, the equation to model the cables is y = -60/40000x^2 + 60, or simplified, y = -0.0015x^2 + 60.

Sat scores are distributed with a mean of 1,500 and a standard deviation of 300. you are interested in estimating the average sat score of first year students at your college. if you would like to limit the margin of error of your 95% confidence interval to 25 points, how many students should you sample?
Answers
To estimate the average SAT score of first-year students at a college with a 95% confidence interval and a margin of error of 25 points, you would need to sample approximately 554 students.
Explanation:This question involves using the concepts of mean, standard deviation, margin of error, and confidence intervals from probability and statistics. To determine the sample size needed to estimate the average SAT score with a certain margin of error, we'll use the formula for the sample size required for estimating a population mean in statistics:
n = (Z*σ/E)^2
Where:
n is the sample size Z is the Z-score (for a 95% confidence interval, Z is 1.96) σ is the standard deviation (300 in this case) E is the margin of error (25 in this case)
Plugging the values into the formula, we get:
n = (1.96*300/25)^2 ≈ 553.47
As we cannot have a fraction of a student, we always round up to ensure our margin of error requirement is met. Therefore, you would need to sample approximately 554 students.

To limit the margin of error of your 95% confidence interval to 25 points, given the standard deviation is 300, use the formula for the margin of error for a confidence interval and solve for the sample size 'n'. Approximately 553 students should be sampled.
Explanation:For this question, we can use the formula for the margin of error for a confidence interval which is calculated as: Margin of Error = z * (σ/√n). Here, 'z' represents the z-score, 'σ' is the standard deviation, and 'n' is the sample size.
In this case, we wish to have a 95% confidence level. From z-tables, we know that the z-value for a 95% confidence level is approximately 1.96. We want a margin of error of 25 points. The standard deviation (σ) for the dataset is said to be 300.
So, we can rearrange our formula to solve for 'n', giving us: n = (z * σ / Margin of Error)². Substituting in our numbers, we get n = (1.96 * 300 / 25)². So, to limit the margin of error on your 95% confidence interval to 25 points, you will need to sample approximately 553 students.

Assume that adults have iq scores that are normally distributed with a mean of 100100 and a standard deviation of 15. find the third quartile upper q 3q3, which is the iq score separating the top 25% from the others.
Answers
Final answer:
The third quartile (Q3) of IQ scores, which separates the top 25% of scores, is approximately 110.125 for a normal distribution with a mean of 100 and a standard deviation of 15.
Explanation:
To find the third quartile (Q3) of IQ scores, which is the value that separates the top 25% from the others in a normally distributed data set, we use the properties of the normal distribution. The mean IQ score is 100 and the standard deviation is 15. Q3 corresponds to the 75th percentile in a normal distribution.
To find the third quartile (Q3), we often refer to the z-score table or use a statistical software or calculator that can handle normal distribution calculations. The z-score corresponding to the 75th percentile is approximately 0.675. We can then use the formula for z-scores:
Q3 = mean + z*(standard deviation)
Q3 = 100 + 0.675*15
Q3 = 100 + 10.125
Q3 = 110.125
Thus, the third quartile IQ score, separating the top 25% of scores from the rest, is approximately 110.125.
To find Q3 for IQ scores (mean 100, SD 15), calculate 75th percentile: [tex]\( Q3 = 100 + 0.674 \times 15 = 110.11 \).[/tex]
To find the third quartile (upper Q3) of IQ scores, we need to determine the IQ score that separates the top 25% from the rest. Given that IQ scores are normally distributed with a mean of 100 and a standard deviation of 15, we can use the properties of the normal distribution to find this value.
1. Identify the z-score corresponding to the third quartile (Q3):
- The third quartile (Q3) corresponds to the 75th percentile of the normal distribution.
- Using the standard normal distribution table or a calculator, the z-score for the 75th percentile is approximately 0.674.
2. Convert the z-score to an IQ score:
- Use the formula for converting a z-score to a value in a normal distribution:
[tex]\[ X = \mu + z \sigma \][/tex]
where:
- [tex]\( \mu \)[/tex] is the mean (100)
- [tex]\( \sigma \)[/tex] is the standard deviation (15)
- [tex]\( z \)[/tex] is the z-score (0.674)
3. Calculate the IQ score:
[tex]\[ Q3 = 100 + (0.674 \times 15) = 100 + 10.11 = 110.11 \][/tex]
Therefore, the third quartile (Q3) IQ score, which separates the top 25% from the others, is approximately 110.

Answers
Answer: First Option is correct.
Step-by-step explanation:
Since we have given that
[tex](4x^3+2x^2-18x+38)\div(x+3)[/tex]
We will apply the "Remainder Theorem ":
So, first we take
[tex]g(x)=x+3=0\\\\g(x)=x=-3\\\\and\\\\f(x)=4x^3+2x^2-18x+38[/tex]
So, we will put x=-3 in f(x).
[tex]f(-3)=4\times (-3)^3+2\times (-3)^2-18\times (-3)+38\\\\f(-3)=-108+18+54+38\\\\f(-3)=2[/tex]
So, Remainder of this division is 2.
Hence, First Option is correct.
The remainder of the given expression is 2 and this can be determined by using the factorization method.
Given :
Expression -- [tex]\rm \dfrac{4x^3+2x^2-18x+38}{x+3}[/tex]
The factorization method can be used in order to determine the remainder of the given expression.
The expression given is:
[tex]\rm =\dfrac{4x^3+2x^2-18x+38}{x+3}[/tex]
Try to factorize the numerator in the above expression.
[tex]\rm =\dfrac{4x^3+12x^2-10x^2-30x+12x+36+2}{x+3}[/tex]
[tex]\rm = \dfrac{4x^2(x+3)-10x(x+3)+12(x+3)+2}{(x+3)}[/tex]
Simplify the above expression.
[tex]\rm = (4x^2-10x+12) + \dfrac{2}{(x+3)}[/tex]
So, the remainder of the given expression is 2. Therefore, the correct option is A).
