Answer:

Step-by-step explanation:

f(x) = 2 / (x^2 - 1) is better written as

                 2

f(x) = ------------------

         (x - 1)(x + 1)

This is undefined at x = -1 and x = 1; there are vertical asymptotes at x = -1 and x = 1.

The y-intercept is found by letting x = 0; we get

                 2

f(x) = ------------------ = -2    =>    (0, -2)

         (0 - 1)(0 + 1)

Please, next time, share the answer choices.  Thank you.

By analyzing the asymptotes we can find the graph of the rational function. Also a graph is provided below.

We have the rational function:

f(x) = (2x)/(x^2 - 1).

First, you can see that we have two zeros on the denominator. One happens when x = 1 and the other when x = -1.

This means that the graph of this function will have two vertical asymptotes at these values. (four actually as we have one going to each end in each point).

With that description we can find the graph of the function, I will also post it so you can recognize it.

The CD that compounds more frequently will pay more interest; thus, monthly compounding yields more interest than quarterly, which in turn is more than semi-annually, with annual compounding paying the least.

When comparing the different compounding frequencies for a Certificate of Deposit (CD) with the same annual interest rate, the compounding option that pays more interest is the one that compounds more frequently. Compounding can occur on an annual, semi-annual, quarterly, or monthly basis. The more frequently the interest is compounded, the greater the amount of interest will be earned because each compounding period, the interest is calculated on the initially invested amount plus the previously earned interest.

For example, if interest is compounded monthly, it will be compounded 12 times a year, and each month's interest will begin to earn interest in subsequent months. Similarly, if interest is compounded quarterly, it will be compounded 4 times a year, and semi-annually compounding will occur twice a year. The least frequent is annually compounding, with only one compound per year.

Therefore, the CD that compounds monthly will pay the most interest, followed by the one that compounds quarterly, then semi-annually, and the least will be the CD that compounds annually, assuming the nominal interest rate is the same for all.

Answer:

x = 60°

Step-by-step explanation:

The circle is 360°, thus

2y + y = 360

3y = 360 ( divide both sides by 3 )

y = 120°

The tangent- secant angle ABT is one half the measure of the intercepted arc AB, thus

x = 0.5 × 120° = 60°

Answer:

y = -28 ÷ x

Step-by-step explanation:

The standard format of a inversely proportional equation goes by the format of y = k ÷ x. The question asks us to write an equation if y = 7 when x = -4 and y varies inversely with x.

So we substitute the values y = 7 and x = -4 in the equation y = k ÷ x

K = constant, we have to work this out

7 = k ÷ -4

7 × - 4 = k

k = - 4 × 7

k = -28

k = -28 So then we put this back into the original y = k ÷ x to find our final equation which is y = -28 ÷ x

Answer:

B. (−17, 4)

Step-by-step explanation:

We can write the equation of a circle in the form

(x-h)^2 + (y-k)^2 = r^2  where (h,k) is the center and r is the radius

(x + 17)^2 + (y − 4)^2 = 23

(x - -17)^2 + (y − 4)^2 = ( sqrt (23))^2

The center is (-17,4) and the radius is (sqrt(23)

6:8 - 6 red apples to 8 green apples.  1:1.33 - 1 red apple for every 1.33 green apples.  43% of the apples are red and 57% of the apples are green.  

Final answer:

The ratio of green apples to red apples is 4:3, and the ratio of red apples to all apples in the basket is 3:7 after simplification.

Explanation:

To solve the student's question:

First, we find the ratio of green apples to red apples. There are 14 apples in total, 8 of which are green, so 14 - 8 = 6 red apples. The ratio of green to red apples is therefore 8:6, which can be simplified by dividing both sides by 2, resulting in a simplified ratio of 4:3.

Next, we calculate the ratio of red apples to all apples in the basket. Since there are 6 red apples and 14 apples in total, the ratio is 6:14, which simplifies to 3:7 when both sides are divided by 2.

Therefore, the answer for part (a) is a ratio of 4:3, and for part (b) is a ratio of 3:7.

Answer:

The answer is B

Step-by-step explanation: The reason for this is you know that 2 in = 9ft so you multiply 9 to get 36/ the height of the classroom. The times you multiply is by equal to it by you multiply by 2 because 2= 9ft not 1=9ft so you take 4 and multiply by 2 and you get 8.

Answer:

B) 8 inches

Step-by-step explanation:

Since the scale of the drawing is 2:9, we will then make this into two fractions that equal each other to make this easier. To do this we will make the ratio 2:9 into a fraction being 2/9. Then we will make the missing value which is the length of the calssroom on the scale drawing over the actual length of the classroom which is 36. We will then make the fractions equal each other. 2/9 = x/36. We can either cross multiply ( 2 x 36 and 9 * x) or we can make the denominators the same. I am going to make the denominators the same. The equation will then look like this: 8/36=x/36. Now we know the value of x is 8. This makes the answer B) 8 inches.

Answer:

{4, 20}

Step-by-step explanation:

x2 − 24x = −80

divide -24 by 2  and square result   get 144

x^2 - 24x  + 144 =  -80 + 144

(x - 12)^2  =  64

x - 12 = root (64)

x = 12 + 8  or  x = 12 - 8

x = 20 or 4

The solution set of the considered quadratic equation x^2 − 24x = −80 is given by: Option B: {4,20}

The method "completing the squares", as per the name suggests, try to make the quadratic equation of the form such that the x variable is totally covered in single squared term, as the square of a linear expression in x.

The quadratic equation would look something like:

(px + q)^2 = s

where p, q and s are some constants.

We do so, so that we can then use square root and some other operations to get the variable 'x' on one side of the equation, and all the constants on the other side, being solution of the considered  quadratic equation.

Expressing the quadratic equation in such form converts the form of the equation which contains 'x' with different powers in different term to a form which contains 'x' single time.

Suppose that two terms are 'a' and 'b'.

Then, their sum's square is expanded as:

[tex](a+b)^2 = a^2 + 2ab + b^2[/tex]

For this case, the equation considered is :

[tex]x^2 -24x = -80[/tex]

Comparing the left side with [tex]a^2 + 2ab + b^2[/tex], we see that we can use a = x.

Let we try to make the considered equation look more like the equation  [tex]a^2 + 2ab + b^2[/tex] .

[tex]x^2 -24x = -80\\x^2 -2(12)x = -80\\x^2 -2(12)x + 12^2 -12^2 = -80\\x^2 -2(12)x + 12^2 = -80 + 12^2 = 64\\[/tex]

Now, we can use [tex](a+b)^2 = a^2 + 2ab + b^2[/tex] for the left sided expression, as shown below:

[tex]x^2 -2(12)x + 12^2= 64\\\\(x-12)^2 = 64[/tex]

Taking square root, we get:

[tex]\sqrt{(x-12)^2} = \sqrt{64}\\\\(x-12) = \sqrt{(\pm 8)^2} = \pm 8\\or\\\\x = 12 \pm 8\\x = 12+8, x = 12-8\\x = 20, x = 4[/tex]

Thus, the solution set of the considered quadratic equation x^2 − 24x = −80 is given by: Option B: {4,20}

Answer:

99

Step-by-step explanation:

It takes each student 33 seconds to eat an apple. This is done in parallel.

The time it would take if each person ate the exact same amount of apples is 69.6 repeating (calculated by (19 * 33) / 9). However, the apples cannot be cut into parts, so we need to round up to the next multiple of 33. Therefore 99 is the answer.

Answer:

Approximately 883,572 people

Step-by-step explanation:

I'm assuming the region is a circle.

The formula for finding the area of a circle is A=πr².

Since we know that the diameter of the region is 15 miles, and a diameter is 2 times the radius, the radius must be 7.5 miles. We also know that π is equal to 3.14159265359.

A=πr²

A= 3.14159265359×7.5²

A= 3.14159265359×56.25

A=  176.714586764

The region has an area of 176.714586764 square miles.

176.714586764×5000=883572.933822

We can round this number to the nearest whole, but since we cannot have part of a person, the answer is approximately 883,572 people.

Final answer:

To find the number of people who live in a region with a 15-mile diameter and a population density of 5000 people per square mile, we can calculate the area of the region and then multiply it by the population density.

Explanation:

To find the number of people who live in the region, we need to calculate the area of the region and then multiply it by the population density. The region has a 15-mile diameter, so the radius is half of that, which is 7.5 miles. The formula for the area of a circle is A = πr^2, where π is approximately 3.14. Plugging in the values, the area of the region is A = 3.14 × (7.5)^2 = 176.625 square miles.

Next, we multiply the area by the population density of 5000 people per square mile: 176.625 × 5000 = 883,125 people.

Therefore, there are approximately 883,125 people who live in the region.

Answer:

The probability that both of the selected marbles are red is [tex]\frac{3}{28}[/tex]

Step-by-step explanation:

Given

Number of red marbles = 3

Number of blue marbles = 5

Required

Probability of selecting two red marbles (without replacement).

First, we need to get the total number of marbles

Total = Red Marbles + Blue Marbles

Total = 3 + 5

Total = 8

Probability is calculated by: Number of required outcome divided by number of possible outcome.

Since there are 3 red marbles out of a total of 8 marbles;

The probability that the first marble you selected is red is 3/8

From the question, you didn't return the marble back to the container.

This means that, there are 2 red marbles and a total of 7 marbles left in the container.

So, the probability that the next marble selected is red is 2/7

Let P(R and R) represent the probability of selecting two red marbles.

This is calculated by multiplying the probability of picking the first red marble and the second red marble.

Hence,

P(R and R) = [tex]\frac{3}{8} * \frac{2}{7}[/tex]

P(R and R) = [tex]\frac{6}{56}[/tex] --- Reduce to lowest term

P(R and R) = [tex]\frac{3}{28}[/tex]

Hence, the probability that both of the selected marbles are red is [tex]\frac{3}{28}[/tex]
