A polynomial is considered rational if it can be written as a polynomial divided by a polynomial.

Any function that can be expressed as a rational fraction in mathematics—an algebraic fraction in which the numerator and denominator are both polynomials—is referred to as a rational function.

Here,

Given :f (x) = 4/x-3+2.

=> vertical asymptotes :

=> 4/x

and

horizontal asymptotes :

=> -1

The rational function is (x/y)where y≠ 0

So,

x≠0.

can be a rational function for them.

Oblique, vertical, and horizontal asymptotes are the three forms of asymptotes that make up the different types of rational functions. The maximum number of horizontal or oblique asymptotes for a rational function is one, although there can be multiple vertical asymptotes.

Zales's percent markup on the selling price as required in the task content is; 37.5%.

It follows from the task content that the percent markup on the selling price be determined according to the given data.

Since the cost of diamonds is; $800 while the diamonds sell for $1,100. It follows that the markup on the selling price of the diamonds is;

Markup = Selling price - Cost price.

Hence, we have;

Markup = 1,100 - 800.

Therefore, the markup is; $300.

On this note, the percent markup can be determined as follows;

= (300/800) × 100%.

= 37.5%.

Ultimately, the percent markup on the diamonds is: 37.5%.

There are a total of 8 color-wheel size combinations for the kickboard scooter. This means that customers have 8 different options to choose from when selecting the color and wheel size for their scooter.

To determine the total number of color-wheel size combinations for the kickboard scooter, we need to multiply the number of color options by the number of wheel size options.

Given that there are 4 color options (silver, red, blue, and purple) and 2 wheel size options (125mm and 180mm), we can use the multiplication principle to find the total number of combinations:

Total combinations = Number of color options × Number of wheel size options

Total combinations = 4 colors × 2 wheel sizes

Total combinations = 8

Answer:

This is a binomial probability problem with n=8, p=0.64, and we want to find the probability of at least 3 successes (graduating) out of 8 trials (freshmen).

One way to solve this is to use the complement rule: the probability of at least 3 successes is equal to 1 minus the probability of 0, 1, or 2 successes.

P(at least 3 successes) = 1 - P(0 or 1 or 2 successes)

Using the binomial probability formula, we can calculate the probability of each of the three cases:

P(0 successes) = C(8, 0) * 0.64^0 * (1-0.64)^8 = 0.0002

P(1 success) = C(8, 1) * 0.64^1 * (1-0.64)^7 = 0.0037

P(2 successes) = C(8, 2) * 0.64^2 * (1-0.64)^6 = 0.0286

Therefore,

P(at least 3 successes) = 1 - (0.0002 + 0.0037 + 0.0286) = 0.9675

So the probability that at least 3 out of 8 freshmen will graduate after a 4-year period is approximately 0.9675 or 96.75%.

Answer: B

Step-by-step explanation:

The data in the table represents a linear function

A linear function is modeled by the following rule:

y = mx + b

In which:

m is the slope, which is the rate of change, that is, the change in y divided by the change in x.

b is the y-intercept, which is the the value of y when the function crosses the x-axis, that is, when x = 0.

Given;

y= 16 8 0 -8 -16

x= 1 2 3 4 5

Here, all the so components in x are multiple of 8

The population density is 618.93 per square mile.

Step-by-step explanation:

It is given that,

No. of people, N = 70,000

The radius of a city's town hall, r = 6 miles

We need to find the population density. It can be calculated by the formula i.e. number of people divided by area of land such that,

\(P=\dfrac{N}{A}\\\\P=\dfrac{N}{\pi r^2}\\\\P=\dfrac{70000}{\pi (6)^2}\\\\P=618.93\ \text{per square mile}\)

So, the population density is 618.93 per square mile.

Answer:

  87 years

Step-by-step explanation:

The balance (A) in the continuously compounded account will be ...

  A = P·e^(rt)

  A = 6000·e^(0.06t)

__

The balance (A) in the annually compounded account will be ...

  A = P(1 +r)^t

  A = 16000(1 +0.05)^t

These balances are equal when ...

  6000·e^(0.06t) = 16000(1.05^t)

We can divide by 6000 to simplify this a little bit.

  e^(0.06t) = 8/3(1.05^t)

Taking the natural logarithm gives ...

  0.06t = ln(8/3) +t·ln(1.05)

  t(0.06 -ln(1.05)) = ln(8/3) . . . . subtract t·ln(1.05) and factor)

  t = ln(8/3)/(0.06 -ln(1.05)) ≈ 0.980829/0.0112098 ≈ 87.497

Rounded to the nearest year, the balances will be the same after 87 years.

Step-by-step explanation:

The required set of numbers 5, 9, 11, and 14 satisfies all the given conditions.

In mathematics, a set is a logically arranged group of items that can be represented in either set-builder or roster form. Sets are typically denoted by curly brackets; for instance, A = 1, 2, 3, 4 is a set.

a set of four whole numbers that satisfies the given conditions:

5, 9, 11, 14

To check that this set meets the requirements:

The range of the original set (12 - 4 = 8) increased by 2 to become 10 (14 - 4 = 10).

The mean of the original set ((4 + 9 + 10 + 12) / 4 = 8.75) remains the same in the new set ((5 + 9 + 11 + 14) / 4 = 8.75).

The median of the original set is 9.5 (the average of 9 and 10), and the median of the new set is 10 - 1 = 9.

Therefore, the set of numbers 5, 9, 11, and 14 satisfies all the given conditions.

Answer:

\(\theta = 355\)

Step-by-step explanation:

Given

Let the angle be \(\theta\)

\(\theta < 360\)

\(\theta\) is co-terminal with -5

Required

Find \(\theta\)

Start by dividing 5 by 360 (ignore the negative)

\(\frac{5}{360} = 0.0138\)

The nearest integer greater than 0.0138 is 1.

This implies that if you were to draw for this problem, the circle you would draw to show -5 degrees would go around 1 time

So, \(\theta\) is calculated as:

\(\theta = -5 + 1*360\)

\(\theta = -5 +360\)

\(\theta = 355\)

If the two angles are complementary, then their sum is 90 degrees.

The inclination is the separation seen between planes or vectors that meet. Degrees are another way to indicate the slope. For a full rotation, the angle is 360°.

Complementary angle - Two angles are said to be complementary angles if their sum is 90 degrees.

If the two angles are complementary, then their sum is 90 degrees.

The statement X = Y + Yxy is True.

The equation given is:

X = Y + Yxy

To find x = (X- Y) / Yy we have to substitute the value of x in X = Y + Yxy as

X = Y + Yxy

X = Y + Yy (X-Y) / Yy

To solve for x, we can rearrange the equation as:
X = Y +  X - Y

X = X
