Answers

Answer 1

As per the given graph, the rational function that is graphed in the given image is option B: F(x) = x(x+3)(x-3) / (x-3)(x+3) as per the factors.

Based on the graph, we can see that the function has vertical asymptotes at x = -3 and x = 3.

Option A has only one factor of (x+3) and one factor of (x-3), so it would have only one vertical asymptote at x = 3 or x = -3, but not both.

Option B has two factors of (x-3) and two factors of (x+3), so it has two vertical asymptotes at x = 3 and x = -3, which matches the graph.

Option C has only one factor of (x-3) and no factor of (x+3), so it would have only one vertical asymptote at x = 3 or x = -3, but not both.

Option D has only one factor of (x+3) and no factor of (x-3), so it would have only one vertical asymptote at x = -3 or x = 3, but not both.

Therefore, the rational function that is graphed in the given image is option B: F(x) = x(x+3)(x-3) / (x-3)(x+3).

What happens to a consistent slope when the y value starts to decrease and the x value remains the same over time?
A. Y decreases and X decreases

B. Y decreases and X increases

C. Y increases and X increases

D. Y increases and X decreases

Answers

Answer:

If the y value decreases while the x value remains the same over time, then the correct answer would be A. Y decreases and X decreases.

Step-by-step explanation:

Sure! A slope is a measure of the steepness of a line. It is calculated by dividing the change in the y-coordinates (rise) by the change in the x-coordinates (run) between two points on a line. The formula for slope is m = (y2 - y1) / (x2 - x1).

In your question, if the y value decreases while the x value remains the same over time, it means that the change in y-coordinates (rise) is negative while the change in x-coordinates (run) is zero. This results in a vertical line with an undefined slope. Therefore, the correct answer would be A. Y decreases and X decreases.

Aiden gives his dog a dose of liquid vitamins every day. Each dose is 5/8 teaspoon. If the bottle of vitamins contains 12 1/2 teaspoons, how many days will the bottle last Aiden?

Answers

Answer:

20 days

Step-by-step explanation:

We can model this situation using the linear equation, whose general form is

f(x) = mx + b, where m is the slope and b is the y-intercept

f(x) = -5/8x + 25/2, where f(x) is the amount remaining in the vitamin bottle and x is the number of days

Explaining the formula:

We know that the slope must be negative since each successive dose depletes the bottleA slope of -5/8 means that the amount in the bottle decreases by 5/8 tsp for 1 day that passes25/2 is simply 12 1/2 (a mixed number) converted to an improper fraction25/2 is the y-intercept because the bottle starts with 25/2 tsp and when no doses are given (i.e., x = 0), there are 25/2 tsp in the bottle

We essentially want to find the x value that will make f(x) = 0 since that is when the bottle will be empty:

0 = -5/8x + 25/2

-25/2 = -5/8x

20 = x

We can check by plugging in 20 for x and see whether we get 0:

0 = -5/8(20) + 25/2

0 = -25/2 + 25/2

0 = 0

The function is increasing at a rate of 9% a day. The function is decreasing at a rate of 9% a day.​

Answers

The rate of change of the quantity is 90%.

What is the rate of change?

The rate of change (ROC) measures how quickly a variable alters over a predetermined amount of time.  The pace at which one quantity changes in relation to another quantity is known as the rate of change function.

Here, we have

Given: The function f(t) = [tex]300(1.9)^{t}[/tex] represents the change in a quantity over t months.

Since the base of the exponent 1.9 is greater than 1.

The nature of f(t) is increasing.

Now,

f(t+1) = [tex]300(1.9)^{t+1}[/tex]

f(t+1)/f(t) =  [tex]((1.9)^{t+1})/((1.9)^{t}[/tex] = 1.9

Hence, an increase in f(t)

(f(t+1) -f(t))/f(t) = f(t+1)/f(t) - 1

= 1.9 - 1

= 0.9

% increase = 0.9 × 100 = 90%

Hence, the rate of change in the quantity is 90%.

Answer:

To find the values of x for which the expressions x^2 - 10x + 31 and x + 1 are equal to each other, we can set them equal to each other and solve for x.

Setting x^2 - 10x + 31 equal to x + 1:

x^2 - 10x + 31 = x + 1

Rearranging the equation to standard quadratic form:

x^2 - 10x + 30 = 0

Now, we can factorize the quadratic expression:

(x - 5)(x - 6) = 0

Setting each factor equal to zero and solving for x:

x - 5 = 0 or x - 6 = 0

x = 5 or x = 6

The equations when solved would have the solutions of:

a. x = π/4 + kπb.  x = 2π c. x = 0, π/3, and 5π/3

How to solve the equations ?

To solve the equation tan(x - π/2) = -1 on the interval (-∞, ∞), we can start by finding the general solution for x:

x - π/2 = -π/4 + kπ, where k is an integer.

Now, we can solve for x:

x = π/2 - π/4 + kπ

x = π/4 + kπ

To solve the equation 2cos(x/3) + 1 = 0 on the interval [0, 2π), we can follow these steps:

2cos(x/3) + 1 = 0

cos(x/3) = -1/2

x/3 = 2π/3, 4π/3

x = 2π, 4π

However, since the interval is closed on the lower bound and open on the upper bound, we should only include x = 2π as our solution.

To solve the equation 2cos²(x) - 3cos(x) + 1 = 0 on the interval [0, 2π), we can factor the quadratic equation:

(2cos(x) - 1)(cos(x) - 1) = 0

Now, we have two cases to consider:

Case 1: 2cos(x) - 1 = 0

cos(x) = 1/2

x = π/3, 5π/3

Case 2: cos(x) - 1 = 0

cos(x) = 1

x = 0

So, the solutions on the interval [0, 2π) are x = 0, π/3, and 5π/3.

5. The coffee shop recently sold 3 cappuccino and 7 espresso drinks.
What is the probability the next drink will be an espresso?

Answers

Answer:

To find the probability of the next drink being an espresso, we need to know the total number of drinks sold.

In this case, the total number of drinks sold is:

3 cappuccinos + 7 espresso drinks = 10 drinks

The probability of the next drink being an espresso can be calculated by dividing the number of espresso drinks sold by the total number of drinks sold:

Probability of next drink being an espresso = Number of espresso drinks sold / Total number of drinks sold

Probability of next drink being an espresso = 7/10

Probability of next drink being an espresso = 0.7 or 70%

Therefore, the probability of the next drink being an espresso is 0.7 or 70%.

What are Transformation and Reflection?

Single or multiple changes in a geometrical shape or figure are called Geometrical Transformation.

A geometrical transformation in which a geometrical figure changes his position to his mirror image about some point or line or axis is called Reflection.

To find the coordinates of polygon A'B'C'D' after a 180° rotation, we need to reflect each vertex across the x-axis and then the y-axis.

To reflect a point across the x-axis, we change the sign of the y-coordinate.

To reflect a point across the y-axis, we change the sign of the x-coordinate.

Using this method, we can find the coordinates of A'B'C'D':

A(0, 0) reflects to A'(0, 0) (no change)

B(5, 2) reflects to B'(-5, 2) (reflect across y-axis)

C(5, -5) reflects to C'(-5, -5) (reflect across y-axis)

D(0, -3) reflects to D'(0, 3) (reflect across x-axis)

Therefore, the coordinates of polygon A'B'C'D' are:

A'(0, 0), B'(-5, 2), C'(-5, -5), D'(0, 3)

Hence,  the coordinates of polygon A′B′C′D′ if polygon ABCD is rotated 180° are A′(0, 0), B′(−5, 2), C′(−5, −5), D′(0, 3) and the graph is attached is in the attached image.

We can see here that the probability that a randomly selected customer did not purchase a Toes Knows shoe or is not displeased is: 0.939

What is probability?

Mathematics' study of random events and their likelihood of happening is known as probability.

We can calculate the probability thus:

We will use: P(not Toes Knows or not displeased) = 1 - P(Toes Knows and displeased)

Calculating P(Toes Knows and displeased), we have:

P(Toes Knows and displeased) = P(Toes Knows) × P(displeased | Toes Knows).

P(Toes Knows) =  (8+3)/(12+13+10+3+8+3) = 11/49

P(displeased | Toes Knows) = 3/11

Thus, P(Toes Knows and displeased) = (11/49) × (3/11) = 3/49

So, we can now find  the probability that a randomly selected customer did not purchase a Toes Knows shoe or is not displeased which is:

The average child in elementary school brings home 13 pieces of paper to show their parents each week. Students at Little Kids Elementary School are in a program that is supposed to be more focused on digital work than paperwork. In one week, five students brought home to following number of papers: 14, 12, 18, 8, 11


Conduct the steps of hypothesis testing to determine whether there is a different amount of papers brought home by the kids at Little Kids Elementary School compared to normal.

Answers

The steps of "hypothesis-testing" for papers bought home are stating the Null and Alternate Hypothesis, find level-of-significance, collecting data, determining p-value, and making decision.

The "Hypothesis-Testing" is defined as a statistical method used to make inferences about a population based on a sample of data. It involves making a assumption about a population parameter (such as its mean or proportion) and then collecting data to test whether the hypothesis is likely to be true or false.

The steps of hypothesis testing are:

Step 1: State the "Null-Hypothesis"

The null hypothesis (H₀) is = average number of papers brought home by the kids at Little Kids Elementary School is the same as the average for the general population, which is 13.

⇒ H₀: µ = 13,

Step 2: State the alternative hypothesis

The "Alternative-Hypothesis" (Hₐ) is = average number of papers brought home by the kids at Little Kids Elementary School is different from 13.

⇒ Hₐ: µ ≠ 13,

Step 3: Determine the level of significance

Let "significance-level" be "α = 0.05". This means we accept a 5% chance of making a "Type I Error"

Step 4: Collect the data and calculate test-statistic

The sample mean of the number of papers brought home by the kids at Little Kids Elementary School is:

⇒ x' = (14 + 12 + 18 + 8 + 11)/5 = 12.6,

The sample standard deviation is:

⇒ s = √[((14-12.6)² + (12-12.6)² + (18-12.6)² + (8-12.6)² + (11-12.6)²)/4] ≈ 3.71

The "test-statistic" ⇒ t = (x' - µ)/(s/√n);

where n = sample size = (5),

⇒ t = (12.6 - 13)/(3.57/√5) = -0.25,

Step 5: Determine of "p-value",

The "degrees-of-freedom" = 4,   ..because 5 - 1 = 4,

We know that "p-value" for t = -0.63 with 4 "degrees-of-freedom" is approximately 0.8103.

Step 6: Making decision and interpreting results

The p-value is 0.8103 which is greater than "significance-level" of (0.05),

So we fail to reject the null hypothesis. and say that there is not enough evidence to conclude that the average number of papers brought home by the kids at Little Kids Elementary School is different from the population mean of 13.

Therefore, we can say that the digital work program did not have a statistically significant effect on the amount of papers brought home by the students at Little Kids Elementary School.

How do we find Probability?

The measurement through which we find the likelihood of an event to occur is called probability. We cannot predict a lot of events with total certainty. And thus, the chance of a event to occur (i.e. how likely they re going to happen) can be predicted using probability.

Probability of any event to happen can be find as: No of favorable outcomes/Total number of outcomes.

Here,

The total no of outcomes = 1,2,3,4,5,6,7,8,9,10

No of favorable outcomes ={2,3,4,6,8,9,10} = 7

eighteen years ago a woman's age was 20 years more than thrice her daughter's age. how many years ago was the woman's age thrice that of her daughter?

Answers

Answer: 8 years ago

Step-by-step explanation:

w = woman's age

d = daughter's age

Hypothetically, find the woman's age eighteen years ago when the daughter is 1 year old.

(18 years ago):

w = 20 + 3d

w = 20 +3(1)

w = 23

The woman is 23 years old.

Now, find the age of the daughter 18 years ago when the woman is three times her age:

w + x = 3(d + x)

**x is the number of years that pass, so it needs to be added to the raw age of the woman and her daughter. That's why it's inside the parenthesis.**

w + x (- x) = 3d + 3x (- x)

w = 3d + 2x

(23) = 3(1) + 2x

**Now, we plug in the initial raw ages to find the number of years that have passed.**

20 = 2x

x = 10

18 - (10) = 8 years ago

Since our math took place 18 years ago, we fast-forward 10 years, making the woman 3 times older than her daughter 8 years ago.

Tom jogs 4 1/6 miles from his house. He then jogs 5 4/5 miles farther. How many miles has Tom jogged in all? Write your answer as a mixed number in simplest form.

Answers

Tom has jogged 9 29/30 miles in all.

How to solve for the distance

Just add the values that tells us all the distamnce that he jogged

Write the values as improper fraction

(25/6) + (29/5)

To add these fractions, we need to find a common denominator, which is the least common multiple (LCM) of 6 and 5. The LCM of 6 and 5 is 30. Now we can convert each fraction to an equivalent fraction with a denominator of 30:

(25/6) * (5/5) = 125/30

(29/5) * (6/6) = 174/30

Now, add the fractions:

(125/30) + (174/30) = (125 + 174) / 30 = 299/30

Now, let's convert this improper fraction back into a mixed number:

299 ÷ 30 = 9 (remainder 29)

So, the mixed number is 9 29/30.

Tom has jogged 9 29/30 miles in all.

Answer:

  -1

Step-by-step explanation:

You want the average rate of change of the function shown in the graph between x=-1 and x=2.

Y-values

The y-value at x = -1 is 9.

The y-value at x = 2 is 6.

Rate of change

The graph changes by 6-9 = -3 units as x changes by 2 -(-1) = +3 units.

The average rate of change is ...

  (change in y) / (change in x) = -3/3 = -1

The average rate of change from x = -1 to x = 3 is -1.

Show that " if x and y are odd integers, then x+y is even" using an indirect proof ( a proof by contraposition)

Answers

Using a proof by contraposition we can see that the sum must be even.

How to use the proof by contraposition?

Here we know that x and y are odd integers, then we can write thes two numbers as:

x = 2n + 1

y = 2m + 1

Where n and m are integers.

If we use the proof by contraposition, then we will assume that the outcome is also an odd number 2k + 1

Then we can write:

2n + 1 + 2m + 1 = 2k + 1

We can simplify this to get:

2n + 2m + 1= 2k

2(n + m) + 1 = 2k

So there we have an odd number is equal to an even number, that does not make sense, thus, the outcome of the sum can't be odd.

to find the probability of exactly 3
X!
arrivals in one thousandth of a minute, what are the values of y, ×, and e that would be used in that formula?

Answers

The values we used in the Poisson probability formula are:

μ = λ = 0.4168

x = 3

e ≈ 2.718

What is Poisson probability?

The Poisson probability distribution is a statistical distribution that models the probability of a certain number of events occurring in a fixed interval of time or space, given the average rate of occurrence of the events.

The Poisson distribution has a mean and variance of λ. Therefore, in this case, the mean and variance of the number of Internet traffic arrivals in one thousandth of a minute are equal to λ.

We can find the value of μ by dividing the total number of arrivals (7000) by the total time period (16,780):

μ[tex]= 7000/16,780 = 0.4168[/tex]

We can use μ as the value of λ in the Poisson distribution since they are equal.

To find the probability of exactly 3 arrivals in one thousandth of a minute, we use the Poisson probability formula:

P(x=3) = (e^(-λ) * λ^x) / x!

where x = 3.

Substituting the values we have:

[tex]P(x=3)[/tex][tex]= (e^(-0.4168) * 0.4168^3) / 3![/tex]

Using a calculator, we can evaluate e^(-0.4168) to be 0.6596, and simplify the denominator:

[tex]P(x=3) = (0.6596 * 0.0287) / 6[/tex]

[tex]P(x=3) ≈ 0.000305[/tex]

Therefore, the values we used in the Poisson probability formula are:

μ = λ = 0.4168

x = 3

e ≈ 2.718

Given:  A rectangular pyramid with a base of dimensions 7 centimeters by 5 centimeters. The two large triangular faces have a height of 7.6 centimeters. The two small triangular faces have a height of 8 centimeters.

We have to find the surface area of the pyramid.

The rectangular base of the pyramid has a length of 7 centimeters and a width of 5 centimeters, so the area of the rectangular base is 35 cm².

The two large triangular faces have a height of 7.6 centimeters, so the area of each of these faces can be calculated as:

= (1/2)×7×7.6

= 26.6 cm²

Similarly, the two small triangular faces have a height of 8 centimeters, so the area of each of these faces can be calculated as:

= (1/2)×5×8

= 20cm²

The total surface area of the rectangular pyramid is:

= 35cm² + 2×26.6 cm² + 2×20 cm²

= 128.2cm²

A machine that cost $170,000 has an estimated residual value of $17,000 and an estimated useful life of four years. The company uses double-declining-balance depreciation.
Calculate its book value at the end of year 3. (Do not round intermediate calculations.)

Answers

Sure!

To calculate the book value at the end of year 3 using the double-declining-balance method, we need to follow these steps:

1. Calculate the straight-line depreciation rate:

Depreciation rate = 1 / Estimated useful life
Depreciation rate = 1 / 4
Depreciation rate = 0.25 or 25%

2. Calculate the double-declining-balance depreciation rate:

Depreciation rate = 2 x Straight-line depreciation rate
Depreciation rate = 2 x 25%
Depreciation rate = 50%

3. Calculate the accumulated depreciation for the first 3 years:

Year 1: Depreciation expense = Beginning book value x Depreciation rate = $170,000 x 50% = $85,000
Accumulated depreciation after Year 1 = $85,000

Year 2: Depreciation expense = Beginning book value x Depreciation rate = ($170,000 - $85,000) x 50% = $42,500
Accumulated depreciation after Year 2 = $85,000 + $42,500 = $127,500

Year 3: Depreciation expense = Beginning book value x Depreciation rate = ($170,000 - $127,500) x 50% = $21,250
Accumulated depreciation after Year 3 = $127,500 + $21,250 = $148,750

4. Calculate the book value at the end of Year 3:

Book value at end of Year 3 = Beginning book value - Accumulated depreciation
Book value at end of Year 3 = $170,000 - $148,750
Book value at end of Year 3 = $21,250

Therefore, the book value at the end of Year 3 is $21,250.

Find x. Round your answer to the nearest tenth of a degree.

Answers

Applying the tangent ratio, the value of x, to the nearest degree is determined as: 41.8 degree.

How to Find x Using the Tangent Ratio?

The formula we would use to find the value of x is the tangent ratio, which is expressed as:

tan ∅ = length of opposite side / length of adjacent side.

reference angle (∅) = x

Length of opposite side = 17

Length of adjacent side = 19

Plug in the values:

tan x = 17/19

x = tan^(-1)(17/19)

x ≈ 41.8 degree (to nearest tenth of a degree)
