How do you identify the vertical and horizontal asymptotes for rational functions?
To identify the vertical asymptotes, we have to factor the denominator. For horizontal asymptotes, we compare the degrees of the numerator and denominator.
For rational functions, there are vertical and horizontal asymptotes. To identify the vertical asymptotes, we first have to factor the denominator. After that, we should look for values that make the denominator zero. These values can be found by setting the denominator equal to zero and solving for x. The resulting x values would be the vertical asymptotes of the function.
The horizontal asymptote is the line that the function approaches as x goes towards infinity or negative infinity. For rational functions, the horizontal asymptote is found by comparing the degrees of the numerator and the denominator.
If the degree of the numerator is less than the degree of the denominator, the horizontal asymptote is y = 0. If the degree of the numerator is equal to the degree of the denominator, the horizontal asymptote is y = the ratio of the leading coefficients. If the degree of the numerator is greater than the degree of the denominator, there is no horizontal asymptote.

An airplane goes from 0 meters per second to a final velocity of 65 meters per second in 4.8 seconds. What is its acceleration?
Answer:
the acceleration is 13.54m/s^2
Step-by-step explanation:
The computation of the acceleration is given below
As we know that
Acceleration = (Final velocity - initial velocity) ÷ time taken
= (65 meters per second - 0 meters per second) ÷ 4.8 seconds
= 65 meters per second ÷ 4.8 seconds
= 13.54m/s^2
hence, the acceleration is 13.54m/s^2
If f(x)=4x-2 and g(x)=-8x+7, find h(x)=f(x) - g(x)
Please help and explain.
Thank you. :)
Answer:
\(h(x)=12x-9\)
Step-by-step explanation:
We are given the two functions:
\(f(x)=4x-2\text{ and } g(x)=-8x+7\)
And we want to find:
\(h(x)=f(x)-g(x)\)
So, by substitution:
\(h(x)=(4x-2)-(-8x+7)\)
Simplify. Distribute:
\(h(x)=(4x-2)+(8x-7)\)
Rearrange:
\(h(x)=(4x+8x)+(-2-7)\)
Combine like terms. Hence:

Ingrid wants to buy a $17,000 car in 6years. How much money must she deposit at the end of each quarter in an account paying 5.5% compounded quarterly so that she will have enough to pay for her car?
Ingrid needs to deposit approximately $558.95 at the end of each quarter to have enough money to buy the $17,000 car in 6 years.
To calculate the amount Ingrid needs to deposit at the end of each quarter, we can use the future value of an annuity formula. The future value (FV) of an annuity is given by the formula:
FV = P * ((1 + r/n)(n*t) - 1) / (r/n)
Where:
P is the periodic deposit
r is the annual interest rate (as a decimal)
n is the number of compounding periods per year
t is the number of years
In this case, Ingrid wants to accumulate $17,000 in 6 years, with a quarterly compounding rate of 5.5% (0.055) and 4 compounding periods per year. Plugging these values into the formula:
17,000 = P * ((1 + 0.055/4)²⁴ - 1) / (0.055/4)
By solving this equation, we find that Ingrid needs to deposit approximately $558.95 at the end of each quarter to accumulate enough money to pay for her car.

Show complete computation.
Answer:
I have solved it and attached in the explanation.
Step-by-step explanation:
Answer:
\(27a^3-54a^2b+36ab^2-8b^3\)
Step-by-step explanation:
To expand the expression (3a - 2b)³, we can use the Perfect Cube Formula.
\(\boxed{\begin{minipage}{6 cm}\underline{Perfect Cube Formula}\\\\$(x-y)^3=x^3-3x^2y+3xy^2-y^3$\\\end{minipage}}\)
Let:
x = 3ay = 2bSubstitute the values into the formula, and use the exponent rule
\(\boxed{(xy)^n=x^n \cdot y^n}\) :
Therefore:
\(\begin{aligned}(3a-2b)^3&=(3a)^3-3(3a)^2(2b)+3(3a)(2b)^2-(2b)^3\\&=3^3 \cdot a^3-3 \cdot 3^2 \cdot a^2 \cdot 2b+3 \cdot 3a \cdot 2^2\cdot b^2-2^3\cdot b^3\\&=27a^3-3 \cdot 9 \cdot a^2 \cdot 2b+9a \cdot 4b^2-8b^3\\&=27a^3-54a^2b+36ab^2-8b^3\end{aligned}\)
So the expression (3a - 2b)³ expanded is 27a³ - 54a²b + 36ab² - 8b³.
There are two cube-shaped tanks. One of the tank has a 3 m side, while the other one has a side measuring half of the first one. Which tank can store more water and why
Answer: The tank which has 3 m side.
Step-by-step explanation: A cube is a form that has equal sides. To calculate the volume of it, multiply all three sides:
V = length*width*height
Since they are all the same, volume will be:
V = s³
One tank has a 3 m side, so its volume is:
V = 3³
V = 27 m³
The other has half of the first one side, then s = \(\frac{3}{2}\) and volume will be:
V = \((\frac{3}{2})^{3}\)
V = \(\frac{27}{8}\) m³
As you can see, the volume of the second tank is \(\frac{1}{8}\) smaller than the first one. Therefore, the tank which has 3 m side can store more water than the tank with side measuring half of the first.

Given 9²m-¹x 9⁵ = 9m+², calculate the value of m.
The value of m is 1/3.
To solve the equation 9²m⁻¹ × 9⁵ = 9m², we can simplify the equation and solve for the value of m.
Let's simplify the equation step by step:
9²m⁻¹ × 9⁵ = 9m²
Expanding the exponents:
(9²)(9⁵)(m⁻¹) = 9m²
Simplifying the exponents:
9^(2+5)(m⁻¹) = 9m²
Using the property\(a^{(m+n)\)= \(a^m \times a^n\):
9^7(m⁻¹) = 9m²
Applying the power of 9⁷:
9m⁻¹ = 9m²
Dividing both sides by 9m⁻¹:
1 = 9m²/m⁻¹
Dividing with the same base and different exponents, we subtract the exponents:
1 = \(9m^{(2-(-1))\)
Simplifying the exponents:
1 = 9m³
Now, we can solve for m by isolating it on one side of the equation:
m³ = 1/9
Taking the cube root of both sides:
m = ∛(1/9)
The cube root of 1/9 is the same as raising 1/9 to the power of 1/3:
m = \((1/9)^{(1/3)\)
Simplifying the cube root:
m = 1/3

For isosceles trapezoid NKJH point R is the midpoint of leg HN and point T is the midpoint of leg KJ. Compute HJ when NK = (3x - 2) cm,
HJ = (5x +9) cm, and RT = (3x + 6) cm.
In the above isosceles trapezoid,
HJ = 14 cmNK = 1 cmRT = 9 cm.What is the explanation for the above response?
Since R is the midpoint of HN, HR = RN. Similarly, since T is the midpoint of KJ, KT = TJ.
Let's use these properties to write expressions for HJ and NK in terms of x:
HJ = 5x + 9
NK = 3x - 2
Since NKJH is an isosceles trapezoid, we know that HJ = NK + 2RT. Substituting the expressions we found earlier, we get:
5x + 9 = (3x - 2) + 2(3x + 6)
Simplifying this equation gives:
5x + 9 = 9x + 10
Subtracting 5x from both sides gives:
4 = 4x
Dividing both sides by 4 gives:
x = 1
Now that we know x, we can find the values of HJ, NK, and RT:
HJ = 5x + 9 = 14 cm
NK = 3x - 2 = 1 cm

Compare and contrast the four different conic sections (orbits). Discuss their
eccentricities.
The four different conic sections are the circle, ellipse, parabola, and hyperbola. They are called conic sections because they are formed by the intersection of a plane and a cone.
What are conic circles?Circle: A circle is formed when the plane intersects the cone at an angle perpendicular to its axis. The circle has an eccentricity of 0, which means the distance between any point on the circle and its center is always the same.
Ellipse: An ellipse is formed when the plane intersects the cone at an angle that is not perpendicular to its axis. The ellipse has an eccentricity between 0 and 1, which means the distance between the two foci and any point on the ellipse is constant.
Parabola: A parabola is formed when the plane intersects the cone parallel to one of its sides. The parabola has an eccentricity of 1, which means it has a single focus point.
Hyperbola: A hyperbola is formed when the plane intersects the cone at an angle that is greater than the angle formed by the cone's side and its axis. The hyperbola has an eccentricity greater than 1, which means the distance between the two foci and any point on the hyperbola is constant.
In summary, the eccentricity of a conic section describes how stretched or elongated the shape is. A circle has an eccentricity of 0, an ellipse has an eccentricity between 0 and 1, a parabola has an eccentricity of 1, and a hyperbola has an eccentricity greater than 1.

7. The owner of a bar has analyzed the data pertaining to the number of alcoholic drinks bar patrons typically order. She has found that 8% of customers order 0 alcoholic beverages, 32% order 1 alcoholic beverage, 39% order 2 alcoholic beverages, 18% order 3 alcoholic beverages, and 3% order 4 alcoholic beverages. Let x = the random variable representing the number of alcoholic drinks a randomly selected customer orders. Find: a) P(x????2) b) P(x????2) c) What is the probability that a randomly selected customer orders at least one alcoholic drink? d) What is the mean number of alcoholic drinks ordered by customers at this bar? e) What is the standard deviation for the number of alcoholic drinks ordered by customers at this bar?
a) P(x ≥ 2) = 60%
b) P(x > 2) = 21%
c) P(at least one alcoholic drink) = 92%
d) Mean = 1.76 drinks
e) Standard Deviation ≈ 0.692 drinks
To solve this problem, let's analyze the given data:
a) P(x ≥ 2): This represents the probability that a randomly selected customer orders two or more alcoholic drinks.
From the given data, we know that:
39% of customers order 2 alcoholic drinks.
18% of customers order 3 alcoholic drinks.
3% of customers order 4 alcoholic drinks.
To find the probability of ordering two or more alcoholic drinks, we sum up the probabilities of ordering 2, 3, and 4 alcoholic drinks:
P(x ≥ 2) = P(x = 2) + P(x = 3) + P(x = 4)
= 39% + 18% + 3%
= 60%
Therefore, the probability that a randomly selected customer orders two or more alcoholic drinks is 60%.
b) P(x > 2): This represents the probability that a randomly selected customer orders more than two alcoholic drinks.
To find this probability, we sum up the probabilities of ordering 3 and 4 alcoholic drinks:
P(x > 2) = P(x = 3) + P(x = 4)
= 18% + 3%
= 21%
Therefore, the probability that a randomly selected customer orders more than two alcoholic drinks is 21%.
c) To find the probability that a randomly selected customer orders at least one alcoholic drink, we need to find the complement of the probability of ordering zero alcoholic drinks:
P(at least one alcoholic drink) = 1 - P(x = 0)
= 1 - 8%
= 92%
Therefore, the probability that a randomly selected customer orders at least one alcoholic drink is 92%.
d) The mean (or average) number of alcoholic drinks ordered by customers at this bar can be found by multiplying the number of drinks ordered by their respective probabilities and summing them up:
Mean = (0 × 8%) + (1 × 32%) + (2 × 39%) + (3 × 18%) + (4 × 3%)
= 0 + 0.32 + 0.78 + 0.54 + 0.12
= 1.76
Therefore, the mean number of alcoholic drinks ordered by customers at this bar is 1.76.
e) The standard deviation for the number of alcoholic drinks ordered can be calculated using the following formula:
Standard Deviation = sqrt([Σ(x - μ)² × P(x)], where Σ denotes summation, x represents the number of drinks, μ is the mean, and P(x) is the probability of x.
Using the above formula, we can calculate the standard deviation as follows:
Standard Deviation = sqrt([(0 - 1.76)² × 0.08] + [(1 - 1.76)² × 0.32] + [(2 - 1.76)² × 0.39] + [(3 - 1.76)² × 0.18] + [(4 - 1.76)² × 0.03])
= sqrt([3.8912 × 0.08] + [0.1312 × 0.32] + [0.016 × 0.39] + [0.2744 × 0.18] + [2.3072 × 0.03])
= sqrt(0.312896 + 0.0420224 + 0.00624 + 0.049392 + 0.069216)
