now, for any "x" value, the numerator will give you a positive root, say x = -10, then 9(-10)^2 +2 will be 902, square root of that is about 30.
whilst for the denominator, that'd be 2(-100) -9, or -209.
as you can see, the denominator for any "x" value, has larger jumps then the numerator, and because of that the rational itself, will always have a larger and larger and negative denominator.
so it may go from say -1/100 to -1/1000000 and so on as "x" progresses, going ever closer and closer to 0.

What is the correct order of the following numbers? -17/10, -2, -(1.2)2
Answers
Answer:
The correct order from least to greatest is: [tex]\(-2\), \(-1.7\), \(-1.44\).[/tex]
Explanation:
To determine the correct order of the given numbers, let's first simplify them:
1. [tex]\(-\frac{17}{10}\)[/tex] is equivalent to [tex]\(-1.7\).[/tex]
2. [tex]\(-2\)[/tex] remains as is.
3. [tex]\(-(1.2)^2 = -1.44\), as \(1.2^2 = 1.44\)[/tex] and the negative sign is applied.
Now, we have:
1. [tex]\(-1.7\)[/tex]
2. [tex]\(-2\)[/tex]
3. [tex]\(-1.44\)[/tex]
So, the correct order from least to greatest is: [tex]\(-2\), \(-1.7\), \(-1.44\).[/tex]
Margo borrows $600, agreeing to pay it back with 4% annual interest after 18 months. How much interest will she pay?
Answers
Margo will pay $36 in interest after borrowing $600 with a 4% annual interest rate for 18 months. We calculate this using the simple interest formula.
Explanation:The question is asking us to figure out how much interest Margo will pay after borrowing $600 with a 4% annual interest rate, or simple interest rate, over the course of 18 months. A core concept here is understanding how simple interest is calculated.
The simple interest formula we'll be using is: Interest = Principal x Rate x Time. The Principal is the amount of money initially borrowed, Rate is the annual interest rate (in decimal form), and Time is the length of time the money is borrowed for, expressed in years.
So in Margo's case, the Principal is $600, the Rate is 4% (or 0.04 in decimal form), and Time is 18/12 or 1.5 years, because 18 months is equal to 1.5 years.
When we apply these amounts to the formula we get: Interest = $600 x 0.04 x 1.5, which equals $36. So Margo will pay $36 in interest.

Find the average value of f over region
d. f(x, y) = 7xy, d is the triangle with vertices (0, 0), (1, 0), and (1, 8).
Answers
The average value of [tex]f(x,y)[/tex] over [tex]D[/tex] is given by the ratio
[tex]\dfrac{\displaystyle\iint_Df(x,y)\,\mathrm dA}{\displaystyle\iint_D\mathrm dA}[/tex]
The denominator is just the area of [tex]D[/tex], which we already know. The average value is then simplified to
[tex]\displaystyle\frac74\iint_Dxy\,\mathrm dA[/tex]
In the [tex]x,y[/tex]-plane, we can describe the region [tex]D[/tex] as all points [tex](x,y)[/tex] that lie between the lines [tex]y=0[/tex] and [tex]y=8x[/tex] (the lines which coincide with the triangle's base and hypotenuse, respectively), taking [tex]0\le x\le1[/tex]. So, the integral is given by, and evaluates to,
[tex]\displaystyle\frac74\int_{x=0}^{x=1}\int_{y=0}^{y=8x}xy\,\mathrm dy\,\mathrm dx=\frac78\int_{x=0}^{x=1}xy^2\bigg|_{y=0}^{y=8x}\,\mathrm dx[/tex]

To find the average value of the function f(x, y) = 7xy over the triangular region defined by vertices (0, 0), (1, 0), and (1, 8), compute the area of the triangle and then calculate the double integral of the function over the region, divided by the area. The bounds for the double integral will be defined by the region.
Explanation:To find the average value of f over the given triangular region, we first need to find the area of the region. The given region is a triangle with vertices (0, 0), (1, 0), and (1, 8). This triangle has a base of 1 (the difference in x coordinates) and a height of 8 (the difference in y coordinates), so its area is (1/2)*base*height=(1/2)*1*8=4.
Next, we integrate the function f(x, y) = 7xy over the triangular region, and divide by the area of the region, to find the average value. Setting up and computing the double integral will provide the total value of the function over the region. The bounds for the double integral will be defined by the region, so we will integrate x from 0 to 1 and y from 0 to 8. The average value is then given by the total value divided by the area, or (1/4)*double integral of f(x, y) dy dx.

If ∠A and ∠B are supplementary angles and m∠A = 3m∠B, find m∠A and m∠B.
Answers
m ∠A=3(m ∠B) and m ∠B=?
m ∠A + m ∠B=180°
3 (m ∠B) + m ∠B=180°
4 m ∠B=180°
4/4 m ∠B=180°/4
m ∠B=45° and m ∠A=3(m ∠B)=3 (45)=135°
To find the measures of angles ∠A and ∠B, we can use the fact that they are supplementary angles and the given relationship between their measures. By solving a system of equations, we can determine that m∠A is 135 and m∠B is 45.
Explanation:To find the measures of the angles ∠A and ∠B, we need to use the fact that they are supplementary angles and the relationship between their measures. Let's start by understanding what supplementary angles are.
Supplementary angles are two angles that add up to 180 degrees. In this case, ∠A and ∠B are supplementary, so we can write the equation:
m∠A + m∠B = 180
We are also given that the measure of ∠A is three times the measure of ∠B, so we can write another equation:
m∠A = 3m∠B
Now we can substitute m∠A in the first equation with 3m∠B:
3m∠B + m∠B = 180
Combining like terms, we get:
4m∠B = 180
Finally, we can solve for m∠B by dividing both sides of the equation by 4:
m∠B = 45
Since m∠A is three times m∠B, we can find m∠A by multiplying 45 by 3:
m∠A = 135

For a normal population with a mean of m = 80 and a standard deviation of s = 10, what is the probability of obtaining a sample mean greater than m = 75 for a sample of n = 25 scores? p = 0.0062 p = 0.9938 p = 0.3085 p = 0.6915
Answers
The calculated z-score is -2.5, and the corresponding probability is 0.9938, meaning there is a 99.38% chance of drawing a sample with a mean greater than 75.
To find the probability of obtaining a sample mean greater than m = 75 for a sample of n = 25 scores when the population mean is m = 80 and the standard deviation is s = 10, we will use the concept of sampling distributions and the Central Limit Theorem.
First, we need to calculate the standard error of the mean (SEM), which is the standard deviation of the sampling distribution of the sample mean.
The SEM is calculated using the formula [tex]SEM = s / \sqrt{n[/tex] where s is the population standard deviation and n is the sample size.
Here, SEM = [tex]10 / \sqrt{25[/tex]
= 10 / 5
= 2.
Next, we convert the sample mean to a z-score to find out how many standard errors the sample mean is from the population mean.
The z-score is calculated using the formula z = (M - m) / SEM, with M being the sample mean and m the population mean.
Therefore, z = (75 - 80) / 2 = -5 / 2 = -2.5.
Looking at the standard normal distribution table or using statistical software, we find that the probability associated with a z-score of -2.5 is approximately 0.9938. This means that the probability of obtaining a sample mean greater than 75 is 0.9938.

a cleaning service order 7 large bottles and 5 small bottles of cleaning products each large bottle has 122 Oz each small bottle has 68 Oz which is the best estimate of the total amount of cleaning products that cleaning service orders
Answers
Final answer:
The best estimate of the total amount of cleaning products that the cleaning service orders is 1,194 Oz.
Explanation:
To find the best estimate of the total amount of cleaning products that the cleaning service orders, we need to calculate the total amount of cleaning products in the large bottles and small bottles separately and then add them together.
Each large bottle has 122 Oz, and the cleaning service orders 7 of them. So the total amount of cleaning products in the large bottles is 7 x 122 = 854 Oz.
Each small bottle has 68 Oz, and the cleaning service orders 5 of them. So the total amount of cleaning products in the small bottles is 5 x 68 = 340 Oz.
To get the best estimate of the total amount of cleaning products, we add the amounts in the large bottles and small bottles together: 854 + 340 = 1,194 Oz.

A market research firm conducts telephone surveys with a 44% historical response rate. what is the probability that in a new sample of 400 telephone numbers, at least 150 individuals will cooperate and respond to the questions? in other words, what is the probability that the sample proportion will be at least 150/400 = .375? calculate the probability to 4 decimals.
Answers
To calculate the probability that at least 150 individuals will cooperate and respond to the questions in a new sample of 400 telephone numbers with a historical response rate of 44%, we use the binomial distribution formula.
Explanation:To calculate the probability that at least 150 individuals will cooperate and respond to the questions, we need to use the binomial distribution formula. The formula is:
P(X ≥ k) = 1 - P(X
Where n is the sample size, k is the desired number of successes, p is the historical response rate, q = 1 - p is the failure rate.
In this case, n = 400, k = 150, p = 0.44, q = 1 - 0.44 = 0.56. Plugging these values into the formula, we get:
P(X ≥ 150) = 1 - P(X<150)
We can use a software or calculator to evaluate this expression. The probability is approximately 0.9328 to 4 decimal places.
