at which values of x does the graph of f(x)=x^2-x-2/(x^2-1)(x^2-16) have a vertical asymptope? check all that apply
Answer:
x = -4, 1, 4
Step-by-step explanation:
The function is given as:
f(x) = (x² - x -2)/[(x² - 1)(x² -16)]
We want to find the values of x where the graph will have vertical assymptote.
Vertical asymptotes are defined as vertical lines which correspond to the values of x that will make the denominator of a rational function to be zero.
Thus, to get the values of x that we will have vertical assymptotes, we have to equate the denominator to zero.
We have;
[(x² - 1)(x² -16)] = 0
Thus,
x² - 1 = 0
Or
x² - 16 = 0
So;
x² = 1
x = √1
x = 1
Or
x² = 16
x = ±√16
x = ±4
Values of x that give vertical assymptote are;
x = -4, 1, 4

solve for x The value of x that would make q || r is
Answer:
x = 12
Step-by-step explanation:
If line r and line a are parallel, therefore:
(11x - 28) + (7x - 8) = 180° (consecutive interior angles are supplementary)
Solve for x
11x - 28 + 7x - 8 = 180
Add like terms
18x - 36 = 180
18x = 180 + 36 (addition property of equality)
18x = 216
x = 216/18 (division property of equality)
x = 12
Which of the graphs below represents the soltuion set for d - 4 > -3?
Answer:
Answer choice "C".
Step-by-step explanation:
In this question, we have to find the graph that fits the inequality.
First, we need to simplify the inequality.
Solve:
d - 4 > -3
Add 4 to both sides.
d > 1
Now, we can find which graph fits the inequality.
We know that the graph has to start at 1, so we can already eliminate answer choices A, B, and D.
General rule of them is that the direction of the arrow is the opposite direction of the inequality sign.
If the inequality is ">", the arrow on the graph should be pointed rightward (→)
If the inequality is "<", the arrow on the graph should be pointed leftward (←)
Since out inequality sign is ">", the arrow has to be pointing rightward, therefore making answer choice "C" the right answer.
what is the inverse of y= 10^x +8?
Answer:
[tex]x = \log_{10}(y - 8)[/tex], where [tex]y > 8[/tex].
Step-by-step explanation:
The question is asking for an expression for [tex]x[/tex] in terms of [tex]y[/tex].
The first step is to move as many constants away from the side with [tex]x[/tex] as possible. In this question, that could be done by subtracting [tex]8[/tex] from both sides of the equation.
[tex]y - 8 = 10^{x} + 8 - 8[/tex].
[tex]y - 8 = 10^{x}[/tex].
Notice how [tex]x[/tex] is in the position of an exponent. Logarithms could help move [tex]x[/tex] out of that position.
For any base [tex]b > 0[/tex]:
[tex]\log_{b} b^{x} = x\, \log_{b}\, b = x[/tex].
In this question, [tex]10[/tex] would be the base. That is: [tex]b = 10[/tex].
Take the logarithm (with [tex]10[/tex] as the base) of both sides of the equation [tex]y - 8 = 10^{x}[/tex]:
Left-hand side: [tex]\log_{10} (y - 8)[/tex].Right-hand side: [tex]\log_{10} \left(10^{x}\right) = x\, \log_{10}\left(10\right) = x[/tex].Equate both sides to find an expression for [tex]x[/tex]:
[tex]x = \log_{10}(y - 8)[/tex].

Suppose that you work for a company that offers $25 and $60 gift certificates. Determine the money denominations that you can create using these denominations. Then use strong induction to prove your conjecture.
Answer:
The money denominations that can be created for the $25 and $60 gift certificates are:
$5, $10, $20, and $50.
Step-by-step explanation:
To give the $25 gift certificate to a worker, the company will give either two of $10 plus one of $5 denominations or one of $20 plus one of $5 denominations. These denominations will result in the same $25.
To give the $60 gift certificate to a worker, the company will either give one of $50 and one of $10 denominations, three of the $20 denominations, or six of the $10 denominations. These denominations in their different combinations will result in the same $60.

For a specific location in a particularly rainy city, the time a new thunderstorm begins to produce rain (first drop time) is uniformly distributed throughout the day and independent of this first drop time for the surrounding days. Given that it will rain during some period on both of the next two days, what is the probability that the first drop of rain will be felt between 9:15 AM and 2:50 PM on both days
Answer:
The required probability = 0.0541
Step-by-step explanation:
From the given information:
The probability that it will rain throughout the day is uniformly distributed & independent of the surrounding days.
Assuming that (P₁) represents the probability that it will rain between 9:15 am to 2:50 pm on day 1.
The time interval is 5 hours 35 minutes long.
= 5.583333 hours long
Thus;
P₁ = 5.583333/24
P₁ = 0.2326
Assuming that (P₂) represents the probability that it will rain between 9:15 am to 2:50 pm on day 2.
P₂ = P₁ = 0.2326
Therefore, the total probability = P₂ × P₁ (independent events)
= 0.2326 × 0.2326
= 0.05410276

What are the possible numbers of positive, negative, and complex zeros of f(x) = −x6 − x5 − x4 − 4x3 − 12x2 + 12
Answer:
Positive roots = 1 or 0
Negative roots = 0, 2, or 4
Complex roots = 0, 2, 4, or 6
Step-by-step explanation:
We are given the polynomial:
f(x) = -x⁶ - x⁵ - x⁴ - 4x³ − 12x² + 12
Now, by inspection, the highest degree is 6 and as such the polynomial is therefore a polynomial with more than 2 as a degree.
Applying Descartes Rule of Signs to the polynomial :
f(x) = -x⁶ - x⁵ - x⁴ - 4x³ − 12x² + 12
Signs are: - - - - - +
There is only 1 sign change and thus, it means there is 1 or 0 positive roots
To find number of negative roots, we will use f(-x);
f(−x) = -(−x)⁶ - (−x)⁵ - (−x)⁴ - 4(−x)³ − 12(−x)² + 12(−x)
f(-x) = -x⁶ + x⁵ - x⁴ + 4x³ − 12x² - 12
Signs are: - + - + - -
There are 4 sign changes and thus, it means there are 4, 2 or 0 negative roots
Thus; Complex roots = 0, 2, 4, or 6

Jeff is making cookies for his school. He needs 150 cookies. One recipe makes 60 cookies and uses 1.5 cups of butter. How many tablespoons of butter will be needed to make 150 cookies? (1 cup = 16 Tbsp.) Show how to use unit fractions to solve this problem.
Answer
Since one recipe makes 60 cookies, we can write the unit fraction LaTeX: \frac{1\text{ recipe}}{60\text{ cookies}}1 recipe 60 cookies. Since one recipe uses 1.5 cups of butter, we can write the unit fraction LaTeX: \frac{1.5\text{ cups butter}}{1\text{ recipe}}1.5 cups butter 1 recipe. And since 1 cup = 16 Tbsp., we can write the unit fraction LaTeX: \frac{16\text{ Tbsp}}{1\text{ cup}}16 Tbsp 1 cup.
Multiply:
LaTeX: \frac{150\text{ cookies}}{1} \cdot \frac{1\text{ recipe}}{60\text{ cookies}} \cdot \frac{1.5\text{ cups butter}}{1\text{ recipe}} \cdot \frac{16\text{ Tbsp}}{1\text{ cup}}150 cookies 1 ⋅ 1 recipe 60 cookies ⋅ 1.5 cups butter 1 recipe ⋅ 16 Tbsp 1 cup
= LaTeX: \frac{150(1)(1.5)(16)}{1(60)(1)(1)} 150 ( 1 ) ( 1.5 ) ( 16 ) 1 ( 60 ) ( 1 ) ( 1 )
= 60 Tbsp. butter
To make 150 cookies 60 tablespoons of butter is needed.
What are ratio and proportion?A ratio is a comparison between two similar quantities in simplest form.
Proportions are of two types one is the direct proportion in which if one quantity is increased by a constant k the other quantity will also be increased by the same constant k and vice versa.
In the case of inverse proportion if one quantity is increased by a constant k the quantity will decrease by the same constant k and vice versa.
From the given information we can solve this problem by using the proportional method.
Assuming 'x' cups of butter is needed to make 150 cookies.
Therefore,
60 : 1.5 : : 150 : x.
60/1.5 = 150/x.
60x = 225.
x = 225/60.
x = 3.75 cups.
Also given that 1 cup is equal to 16 tablespoons.
Therefore, 3.75 cups is equal to (3.75×16) tablespoons.
= 60 tablespoons.

what is the solution to 6(3x +7) = -5(4x -3) - 49 ?
Answer:
x = -2
Step-by-step explanation:
You would first distribute.
6(3x + 7) = -5(4x - 3) - 49 → 18x + 42 = -20x + 15 - 49
We can then calculate difference of 15 and 49.
18x + 42 = -20x + 15 - 49 → 18x + 42 = -20x -34
We can now move the variables to one side of the equation and the numbers on the other side.
18x + 20x + 42 - 42 = -20x + 20x - 34 - 42 → 38x = -76
Then, divide.
38x ÷ 38 = -76 ÷ 38 → x = -2

Answer:
Time taken by kangaroo to travel 5 km = 4.27 minutes.
Step-by-step explanation:
Speed of kangaroo is 44 mph.
Speed of kangaroo = 44 mph = 44 x 1.6 = 70.4 kmph = 19.5 m/s
We need to find how much time it takes to travel 5 km
Distance traveled = 5 km = 5000 m
We have
Distance traveled = Speed x Time taken
5000 = 19.5 x Time taken
Time taken = 256.41 seconds
Time taken = 4.27 minutes.

5. A Major League Baseball stadium sells three types of tickets. Reserved tickets are sold for $20 each, field-level tickets are sold for $50 each, and box seat tickets are sold for $100 each. A graph depicts these three types of tickets sold for their Friday night game. What does the point of intersection represent?
A) When all three ticket prices generate the same revenue.
B) When all three types of tickets have sold the same amount.
C) When all three types of tickets cost the same amount
D) When all three types of tickets reach their maximum revenue
Answer: A) When all three ticket prices generate the same revenue.
Step-by-step explanation:
Reserved tickets cost $20 each.
Field-level tickets cost $50 each.
Seat tickets cost $100 each.
Then if x represents the number of reserved tickets sold, the total revenue for the reserved tickets will be:
R(x) = x*$20
If w represents the number of field-level tickets sold, the total revenue for field-level tickets will be:
F(w) = w*$50
If y represents the number of seat tickets sold, then the total revenue for the seat tickets will be:
S(y) = y*$100
Those equations will intersect when:
R(x) = F(w) = S(y)
This will mean that they will intersect when all three tickets have the same revenue, then the correct option is:
A) When all three ticket prices generate the same revenue.
