Find Vertical And Horizontal Asymptotes

Answers

Answer 1

A vertical asymptote exists of the form x = k where y→∞ or y→ -∞.

A slant asymptote exists of the form y = mx + b where m ≠ 0.

What is the difference between vertical and horizontal asymptotes?

Vertical lines go up and down and are in the form of x = a, where a stands for the common x-coordinate of all locations, whereas horizontal lines go left to right and take the shape of y = b, where b stands for the y-intercept.

A vertical line that directs the function's graph but is not actually a part of it is called a vertical asymptote. Because it appears at an x-value outside of the function's domain, the graph can never cross it. There may be multiple vertical asymptotes for a given function. All common factors are cancelled in the denominator, D(x).

A horizontal asymptote exists of the form y = k where x→∞ or x→ -∞ if the value of the one/both of the limits lim ₓ→∞ f(x) and lim ₓ→ -∞ f(x).

A vertical asymptote exists of the form x = k where y→∞ or y→ -∞.

a.

The slope-intercept form of a linear equation is  y = mx + b.

The  points (-4, 6) and (0, -6):

m = (change in y) / (change in x)

= (-6 - 6) / (0 - (-4))

= -12 / 4

= -3

the y-intercept (b):

6 = -3(-4) + b

6 = 12 + b

b = 6 - 12

b = -6

b.

We will use the points (-4, 6) and (0, -6) and reverse the sign of the y-values. The points for the right side will be  (-4, -6) and (0, 6).

c.

We find slope (m) using the points (-4, -6) and (0, 6):

m = (change in y) / (change in x)

= (6 - (-6)) / (0 - (-4))

= 12 / 4

= 3

Using the 68-95-99.7 Rule, what percent of smartphone users are between 29 and 53 years old?

Answers

a)  The required answer is 2.5% of smartphone users are greater than 53 years old.

To find the percentage of smartphone users greater than 53 years old, we can use the 68-95-99.7 Rule, which refers to the empirical rule for normal distributions. The given mean is 37 years, and the standard deviation is 8 years.

Step 1: Calculate the z-score for 53 years old.
z = (53 - 37) / 8 = 2

A z-score of 2 means the age of 53 is 2 standard deviations above the mean. According to the 68-95-99.7 Rule, approximately 95% of the data falls within 2 standard deviations of the mean (above and below).

The sample mean error is the deviation of the set of means an infinite number of repeated samples from the population.

We are known as mean in mathematics especially in statistics. Its location covered mean median and mode,

Generally means include power mean and f- mean, the function of a mean and angles and cyclical quantities.      


Step 2: Calculate the percentage of users greater than 53 years old.
Since 95% of users are within 2 standard deviations (both above and below), this means that the remaining 5% of users are either below 2 standard deviations (younger than 29 years) or above 2 standard deviations (older than 53 years). As the data is symmetric, we can divide 5% by 2 to get the percentage of users older than 53 years old.z

Answer: 5% / 2 = 2.5% of smartphone users are greater than 53 years old.

b)  The required answer is 95% of smartphone users are between 29 and 53 years old.

To find the percentage of smartphone users between 29 and 53 years old, we know that both ages are 2 standard deviations from the mean (one below and one above).

A measure of the amount of variation or dispersion of a set of values are called standard deviation.

standard deviation  indicates the value is tend to be close to the mean.

Its deviation of a population or sample and a statics are quite different but relate.

The sample mean error is the deviation of the set of means an infinite number of repeated samples from the population.

We are known as mean in mathematics especially in statistics. Its location covered mean median and mode,

Generally means include power mean and f- mean, the function of a mean and angles and cyclical quantities. There are three types of mean is Arithmetic mean ,  Geometric mean and Harmonic mean. The arithmetic mean of a list of numbers. The Geometric mean is an average and useful for sets of positive number. The Harmonic mean is an average is useful for set of numbers.

   

According to the 68-95-99.7 Rule, 95% of the data falls within 2 standard deviations of the mean (above and below).

(b) The "test-statistic" is 10.36,

(c) The "p-value" is 0.0001,

(d) We make a decision to reject the "Null-Hypothesis",

(e) We conclude that the cans of "regular-Coke" have volumes with mean different from 12 ounces.

Part (a) : The "Null-Hypothesis" is that the mean volume of cans of regular Coke is 12 ounces, as stated on the label. The alternative-hypothesis is that the mean volume is different from 12 ounces.

So, H₀ : μ = 12

Hₐ : μ ≠ 12.

Part (b) : The "test-statistic" for a one-sample t-test is calculated as:

t = (x' - μ)/(s / √n),

In this case, x' = 12.19, μ = 12, s = 0.11, and n = 36.

So, t = (12.19 - 12)/(0.11/√36) = 10.36,

Part (c) : We know that for "significance-level" of 0.01. The p-value is 0.0001.

Part (d) : Since the p-value is less than the significance-level of 0.01, we reject the null hypothesis.

use green’s theorem to evaluate z c xy2 dx x dy, where c is the unit circle oriented positively

Answers

The line integral of F over the unit circle C is zero:

∮C F · dr = ∬D curl(F) · dA = 0

Hence, the answer is zero.

To use Green's theorem to evaluate the line integral of the given function around the unit circle, we need to first find its equivalent double integral over the region enclosed by the circle.

Green's theorem relates the line integral of a vector field over a closed curve to the double integral of the curl of the same vector field over the region enclosed by the curve.

Let's consider the vector field [tex]F = (0, 0, xy^2).[/tex]

Its curl is given by:

curl(F) = (∂Q/∂x - ∂P/∂y) i + (∂P/∂x + ∂Q/∂y) j + (∂R/∂x - ∂Q/∂y) k

= (0 - 0) i + (0 + 0) j + (0 - 2xy) k

= -2xy k

Here, P = 0, Q = 0, and[tex]R = xy^2[/tex] are the components of the vector field F.

Now, we can apply Green's theorem to evaluate the line integral of F over the unit circle C:

∮C F · dr = ∬D curl(F) · dA

where D is the region enclosed by the unit circle C and dA is the area element in the xy-plane.

Since the unit circle is given by[tex]x^2 + y^2 = 1,[/tex]  we can use polar coordinates to evaluate the double integral:

∬D curl(F) · dA = ∬D (-[tex]2r^3[/tex] sin θ cos θ) r dr dθ

= -2 ∫[0,2π] ∫[0,1] [tex]r^4[/tex]sin θ cos θ dr dθ

= 0 (since the integrand is odd in sin θ).

Using the product rule, k′(−2)=f(−2)g′(−2)h(−2)+f(−2)g(−2)h′(−2)+f′(−2)g(−2)h(−2). Substituting the given values, we get k′(−2)=(-5)(8)(3)+(-5)(-7)(-10)+(9)(-7)(3)= -120+350-189= 41.

The product rule states that the derivative of the product of two or more functions is the sum of the product of the first function and the derivative of the second function with the product of the second function and the derivative of the first function.

Using this rule, we can find the derivative of k(x) with respect to x. We are given the values of f(−2), f′(−2), g(−2), g′(−2), h(−2), and h′(−2). Substituting these values in the product rule, we can calculate k′(−2). Therefore, the derivative of the function k(x) at x=-2 is equal to 41.

you are the operations manager for an airline and you are considering a higher fare level for passengers in aisle seats. how many randomly selected air passengers must you survey assume that you want ot be 90% confident that the sample percentage is within 3.5 percentage points of the true population percentage

Answers

Rounding up to the nearest whole number, you would need to survey approximately 753 randomly selected air passengers to be 90% confident that the sample percentage is within 3.5 percentage points of the true population percentage.

To determine the sample size needed for estimating a population percentage with a specified margin of error and confidence level, we can use the formula for sample size calculation for proportions. The formula is:

n = (Z^2 * p * (1-p)) / E^2

Where:

n is the required sample size,

Z is the Z-score corresponding to the desired confidence level (for a 90% confidence level, Z ≈ 1.645),

p is the estimated population proportion (since we don't have an estimate, we can use 0.5 for maximum sample size),

E is the desired margin of error (in decimal form).

In this case, the desired margin of error is 3.5 percentage points, which is 0.035 in decimal form.

Plugging in the values, we have:

n = (1.645^2 * 0.5 * (1-0.5)) / 0.035^2

Calculating this expression gives us:

n ≈ 752.93

A ball is thrown straight up with an initial velocity of 54 ft/sec. The height of the ball t seconds after it is thrown is given by the formula f(t) = 54t - 12t^2. How many seconds after the ball is thrown will it return to the ground?

Answers

The ball will return to the ground after approximately 4.5 seconds.

To find the time it takes for the ball to return to the ground, we need to determine when the height of the ball is zero. In other words, we need to solve the equation f(t) = 54t - 12t² = 0.

Let's set the equation equal to zero and solve for t:

54t - 12t² = 0

Factoring out common terms:

t(54 - 12t) = 0

Now, we have two possible solutions for t:

t = 0

This solution represents the initial time when the ball was thrown.

54 - 12t = 0

Solving this equation for t:

54 - 12t = 0

12t = 54

t = 54 / 12

t = 4.5

Answers

Answer:

To find the Taylor polynomial t3(x) for the function f(x) = xe^(-7x) centered at the number a = 0, we will use the formula for the nth-degree Taylor polynomial:

t_n(x) = f(a) + f'(a)(x-a) + f''(a)(x-a)^2/2! + ... + f^n(a)(x-a)^n/n!

First, let's find the first few derivatives of f(x):

f(x) = xe^(-7x)

f'(x) = e^(-7x) - 7xe^(-7x)

f''(x) = 49xe^(-7x) - 14e^(-7x)

f'''(x) = -343xe^(-7x) + 147e^(-7x)

Next, let's evaluate these derivatives at a = 0:

f(0) = 0

f'(0) = 1

f''(0) = -14

f'''(0) = 147

Now we can substitute these values into the formula for t3(x):

t3(x) = f(0) + f'(0)x + f''(0)x^2/2! + f'''(0)x^3/3!

t3(x) = 0 + 1x - 14x^2/2 + 147x^3/6

t3(x) = x - 7x^2 + 49/2 x^3

Answers

The solution set for the logarithmic equation log3(x + 21)-log3(x-5)=3 is x=9.

To solve the logarithmic equation log3(x + 21)-log3(x-5)=3, we can use the quotient rule of logarithms to rewrite the equation as log3[(x + 21)/(x-5)]=3. We know that the domain of a logarithmic function is only valid for positive values inside the parenthesis. Therefore, we must reject any value of x that makes the denominator (x-5) equal to 0. So, x cannot be equal to 5.

Next, we can rewrite the equation without logarithms as 3=3 log3[(x + 21)/(x-5)]. Using the property that a log a(x)=x, we can simplify the equation as 3=(x + 21)/(x-5)³. Multiplying both sides by (x-5)³, we get 3(x-5)³ = x+21.

Expanding the left side of the equation and simplifying, we get 3x³ - 72x² + 498x - 1089 = 0. We can then solve for x using synthetic division or long division, which gives us the solution x=9.

However, we must check if x=9 is a valid solution by plugging it back into the original equation. Since log3(9+21) = log3(30) and log3(9-5) = log3(4), we can simplify the original equation as log3(30/4) = log3(15/2) = 3. Therefore, x=9 is a valid solution.

find the general power series solution of the differential equation y 00 3y 0 = 0, expanded at t0 = 0.

Answers

Therefore, the general power series solution of the differential equation y'' + 3y' = 0, expanded at t0 = 0, is: y(t) = c_0 + c_1 t - (3/2) c_1 t^2 + (9/8) c_1 t^3 - (15/48) c_1 t^4 + ... + (-1)^n (3/(n+2)) c_(n+1) t^(n+2) + ... where c_0 and c_1 are arbitrary constants.

To find the power series solution of the given differential equation, we assume that the solution can be expressed as a power series:

y(t) = ∑(n=0 to ∞) c_n t^n

where c_n is the nth coefficient to be determined.

Taking first and second derivatives of y(t) with respect to t, we get:

y'(t) = ∑(n=1 to ∞) n c_n t^(n-1)

y''(t) = ∑(n=2 to ∞) n(n-1) c_n t^(n-2)

Substituting these expressions into the differential equation, we get:

∑(n=2 to ∞) n(n-1) c_n t^(n-2) + 3∑(n=1 to ∞) n c_n t^(n-1) = 0

Shifting the index of the first summation to start from n=0, we get:

∑(n=0 to ∞) (n+2)(n+1) c_(n+2) t^n + 3∑(n=0 to ∞) (n+1) c_(n+1) t^n = 0

We can simplify this expression by setting the coefficients of each power of t to zero:

(n+2)(n+1) c_(n+2) + 3(n+1) c_(n+1) = 0, for n ≥ 0

Simplifying this expression further, we get:

c_(n+2) = -(3/((n+2)(n+1))) c_(n+1), for n ≥ 0

This gives us a recursive formula for the coefficients c_n in terms of c_0 and c_1:

c_(n+2) = -(3/(n+2)) c_(n+1), for n ≥ 0

c_0 and c_1 are arbitrary constants.

To find the power series solution expanded at t0 = 0, we need to set c_0 = y(0) and c_1 = y'(0) and solve for the remaining coefficients using the recursive formula.

In a language program at a university, 14% of students speak Spanish, 7% speak French an 4% speak both languages. A student is chosen at random from the college. What is the probability that a student who speaks Spanish also speaks French? A) 0.170 B) 0.286 C) 0.030 D) 0.040 E) 0.571

Answers

Given that 14% of students speak Spanish, 7% speak French, and 4% speak both languages, the probability can be determined as 0.286 (option B).

Let's denote the event "speaks Spanish" as S and the event "speaks French" as F. We want to find the probability of F given S, denoted as P(F|S).

Using conditional probability, we have the formula:

P(F|S) = P(F ∩ S) / P(S)

Given that 14% speak Spanish (P(S) = 0.14), 7% speak French (P(F) = 0.07), and 4% speak both languages (P(F ∩ S) = 0.04), we can substitute these values into the formula:

P(F|S) = P(F ∩ S) / P(S) = 0.04 / 0.14 = 0.286

Answers

The integral [tex]\int_0^8 (x - x^3) dx[/tex] does not represent the area under the curve [tex]$y = x - x^3$[/tex] from 0 to 8 i.e., the given statement is false.

The integral [tex]$\int_0^8 (x - x^3) dx$[/tex] represents the definite integral of the function [tex]$y = x - x^3$[/tex] over the interval [0, 8]. This integral calculates the signed area between the curve and the x-axis over that interval. However, it does not represent the area under the curve itself.

To find the area under the curve, we need to take the absolute value of the integrand.

The integrand [tex]$x - x^3$[/tex] can be negative for certain values of x, which would result in a negative contribution to the signed area.

By taking the absolute value of the integrand, we ensure that we only consider the magnitude of the area.

Therefore, to find the actual area under the curve [tex]$y = x - x^3$[/tex] from 0 to 8, we need to evaluate [tex]$\int_0^8 |x - x^3| dx$[/tex]. This integral will give us the true area enclosed by the curve and the x-axis over the specified interval.

Si lanzo 16 monedas al mismo tiempo ¿cual es la probabilidad de obtener 4 sellos?

Answers

The probability of getting exactly 4 tails when tossing 16 coins simultaneously is approximately 0.385 or 38.5%.

How to calculate the probability

In order to calculate the probability of getting a specific number of tails when tossing multiple coins, we can use the binomial probability formula.

In this case, you want to calculate the probability of getting 4 tails out of 16 coins. Plugging the values into the formula:

P(X = 4) = (¹⁶C₄) * (0.5₄) * (0.5¹²))

Calculating the values:

P(X = 4) = (16! / (4! * (16-4)!)) * (0.5⁴) * (0.5¹²)

= (16! / (4! * 12!)) * (0.5⁴) * (0.5¹²)

= (16 * 15 * 14 * 13) / (4 * 3 * 2 * 1) * (0.5⁴) * (0.5¹²)

≈ 0.385

Therefore, the probability of getting exactly 4 tails when tossing 16 coins simultaneously is approximately 0.385 or 38.5%.
