Answer 1

The roots of the function f ( x ) are x = 1 and x = 3

Given data ,

Let the function be represented as f ( x )

Now , the value of f ( x ) is

f ( x ) = x⁴ - 13x³ + 38x² - 23x - 3

On simplifying , we get

The possible factors of the constant term (-3) are ±1 and ±3, while the possible factors of the leading coefficient (1) are ±1.

Now, we can test these factors by substituting them into the function and checking if the result is zero:

f(1) = (1)⁴ - 13(1)³ + 38(1)² - 23(1) - 3 = 1 - 13 + 38 - 23 - 3 = 0

f(-1) = (-1)⁴ - 13(-1)³ + 38(-1)² - 23(-1) - 3 = 1 + 13 + 38 + 23 - 3 = 72

f(3) = (3)⁴ - 13(3)³ + 38(3)² - 23(3) - 3 = 81 - 351 + 342 - 69 - 3 = 0

f(-3) = (-3)⁴ - 13(-3)³ + 38(-3)² - 23(-3) - 3 = 81 + 351 + 342 + 69 - 3 = 840

From the above calculations, we can see that f(1) = f(3) = 0. This means that x = 1 and x = 3 are roots of the polynomial function

Hence , the function is solved and x = 1 and x = 3

In the Northwest Bank waiting line system, assume that the service times for drive-up teller follow an exponential probability distribution with a mean of 100 customers per hour. Use the exponential probability distribution to answer the following questions:
a. What is the probability that the service time is one minute or less?
b. What is the probability that the service time is two minutes or less?
c. What is the probability that the service time is more than two minutes?
d. What is the probability that the service time is between three and seven minutes?

Answers

Calculating this expression, we find that the probability of the service time being one minute or less is approximately 0.6321.

Calculating this expression, we find the probability of the service time being between three and seven minutes is approximately 0.1849.

To answer the questions, we will use the exponential probability distribution formula:

f(x) = λ * e^(-λx)

Where λ is the rate parameter (mean service rate) and x is the service time.

a. To find the probability that the service time is one minute or less, we substitute x = 1 and λ = 100/60 (since there are 60 minutes in an hour and the mean service rate is given per hour):

P(X ≤ 1) = λ * e^(-λx)

P(X ≤ 1) = (100/60) * e^(-(100/60) * 1)

b. To find the probability that the service time is two minutes or less, we substitute x = 2 and λ = 100/60:

P(X ≤ 2) = λ * e^(-λx)

P(X ≤ 2) = (100/60) * e^(-(100/60) * 2)

Calculating this expression, we find that the probability of the service time being two minutes or less is approximately 0.8647.

c. To find the probability that the service time is more than two minutes, we subtract the probability of the service time being two minutes or less from 1:

P(X > 2) = 1 - P(X ≤ 2)

Calculating this expression, we find that the probability of the service time being more than two minutes is approximately 0.1353.

d. To find the probability that the service time is between three and seven minutes, we subtract the probability of the service time being less than three minutes from the probability of the service time being less than seven minutes:

P(3 ≤ X ≤ 7) = P(X ≤ 7) - P(X < 3)

P(3 ≤ X ≤ 7) = (100/60) * e^(-(100/60) * 7) - (100/60) * e^(-(100/60) * 3)

if a car is speeding down a road at 50 miles/hour ( mph ), how long is the stopping distance d50 compared to the stopping distance d25 if the driver were going at the posted speed limit of 25 mph ?

Answers

The stopping distance of D40 is 2.56 times the stopping distance of D25.

Given that are two initial velocities: 40 mph and 25 mph, with which the car's stopping distance is D40 and D25.

The final velocity for both is 0 mph (as the car to a stops).

We need to compare the stopping distance D40 to the stopping distance D25.

Use the third equation of motion for both cases to get the comparison.

The equation is given by:

[tex]v^2 - u^2 = 2as.[/tex]

Case 1)

[tex]0 - 40^2 = 2a(D40)[/tex]

Case 2)

[tex]0 - 25^2 = 2a(D25)[/tex]

Comparing the obtained expressions.

[tex]\frac{40^2}{25^2} = \frac{2a(D40)}{2a(D25)}[/tex]

[tex]2.56 = \frac{D40}{D25}[/tex]

[tex]2.565 \times D25 = D40[/tex]

Hence the stopping distance of D40 is 2.56 times the stopping distance of D25.

Jan creative a pattern using the rule ""add 3."" Bill creates a pattern using the rule ""add 6."" Which describes the relationship between Jan sand Bill’s patterns?

Answers

Jan created a pattern using the rule "add 3," and Bill created a pattern using the rule "add 6." In arithmetic sequences, the nth term is given by the formula a + (n-1)d, where a is the first term and d is the common difference between any two consecutive terms.

The common difference is the difference between each pair of consecutive terms in a sequence. Because Jan's pattern has a common difference of 3, the nth term in her sequence is given by a + (n-1)3, and because Bill's pattern has a common difference of 6, the nth term in his sequence is given by a + (n-1)6.The nth term in both Jan and Bill's sequence is a linear function of n. The slope of a line is the common difference between any two consecutive terms in a sequence.

As a result, the slopes of Jan and Bill's patterns are 3 and 6, respectively. In general, two patterns are in a linear relationship if their slopes are constant multiples of one another. In this case, Bill's pattern is the result of multiplying Jan's pattern by a factor of 2. As a result, their patterns have a linear relationship. Answer: The patterns have a linear relationship because Bill's pattern is the result of multiplying Jan's pattern by a factor of 2.

Find the volume of the following solids.
The base of the solid is the region between the curve y=2√sin x and the interval [0,π] on the x-axis. The cross-sections perpendicular to the x-axis are
a. equilateral triangles with bases running from the x-axis to the curve.
b. squares with bases running from the x-axis to the curve.

Answers

To find the volume of the solid with equilateral triangular cross-sections, we need to integrate the area of each equilateral triangle over the interval [0,π]. The area of an equilateral triangle with side length s is given by (s^2√3)/4. Since the triangles have bases running from the x-axis to the curve y=2√sin x, their side lengths will be 2√sin x. Therefore, the volume is given by the integral:

V = ∫[0,π] (2√sin x)^2√3/4 dx

Simplifying, we get:

V = √3∫[0,π] sin x dx

Using the substitution u = cos x, we get:

V = √3∫[-1,1] √(1 - u^2) du

Using the formula for the integral of the half-circle, we get:

V = (√3/2)π

Therefore, the volume of the solid is (√3/2)π.

To find the volume of the solid with square cross-sections, we need to integrate the area of each square over the interval [0,π]. Since the squares have bases running from the x-axis to the curve y=2√sin x, their side lengths will be 2√sin x.

Therefore, the volume is given by the integral:

V = ∫[0,π] (2√sin x)^2 dx

Simplifying, we get:

V = 4∫[0,π] sin x dx

Using the identity ∫sin x dx = -cos x + C, we get:

V = -4cos x ∣[0,π]

Since cos π = -1 and cos 0 = 1, we get:

V = -4(-1 - 1) = 8

Therefore, the volume of the solid is 8.

Answers

The mean expenses of the XYZ Corporation is 9,811.22.

To compute for the mean expenses of the XYZ Corporation, we need to add up all the total expenses of each city and divide it by the total number of cities.

Total Expenses = 4,933.50 + 6,035.70 + 12,276.00 + 6,237.00 + 14,850.00 + 7,590.00 + 7,260.00 + 6,930.00 + 21,780.00 + 11,220.00
Total Expenses = 98,112.20

Number of Cities = 10

Mean Expenses = Total Expenses / Number of Cities
Mean Expenses = 98,112.20 / 10
Mean Expenses = 9,811.22

The mean expenses of the XYZ Corporation is 9,811.22. Since the answer does not require decimals, we do not need to express it in two decimal places. However, we need to follow the reminder that if the answer is more than three digits, we should not include the comma.

who can determine the perimeter of the following regular nonagon??

Answers

The perimeter of the regular nonagon is approximately 29.7 feet.

The apothem of a regular nonagon divides each of its interior angles into two congruent angles.

Therefore, each of the interior angles of the nonagon measures:

(180 - 360/9)/2 = 140 degrees

The sum of the interior angles of a nonagon is (9-2) * 180 = 1260 degrees. Therefore, the measure of each exterior angle of the nonagon is:

360/9 = 40 degrees

In a regular nonagon, all the sides and angles are congruent, so we can divide it into 9 congruent isosceles triangles. Each of these triangles has base s and height a, and its legs are given by:

l =√s² - (a/2)²

The perimeter P of the nonagon is given by:

P = 9s

Substituting the values of s and a, we get:

l = √3.3²- (1.65/2)²

= 3.018 ft (rounded to 3 decimal places)

P = 9(3.3) = 29.7 ft

x^4-5x^3+7x^2-5x+6=0

Answers

Answer:Therefore, the solutions to the equation x^4 - 5x^3 + 7x^2 - 5x + 6 = 0 are x = 0, x = 1, x = 5.

Step-by-step explanation:

To solve the equation x^4 - 5x^3 + 7x^2 - 5x + 6 = 0, we can use factoring by grouping.

First, we can group the first two and last two terms:

x^4 - 5x^3 + 7x^2 - 5x + 6 = (x^4 - 5x^3) + (7x^2 - 5x + 6)

Next, we can factor out x^3 from the first group and factor out 1 from the second group:

(x^3(x - 5)) + (7x^2 - 5x + 6)

Now, we can group the last two terms of the second group:

x^3(x - 5) + (7x^2 - 3x - 2x + 6)

Then, we can factor out 1 from the terms inside the parentheses and group them:

x^3(x - 5) + (7x^2 - 3x) + (-2x + 6)

Now, we can factor out x from the second and third groups:

x^3(x - 5) + x(7x - 3) - 2( x - 3)

We can simplify the third group by distributing the negative sign:

x^3(x - 5) + x(7x - 3) - 2x + 6

Finally, we can combine the second and third groups:

x^3(x - 5) + x(7x - 5) + 6

So, the factored form of the equation x^4 - 5x^3 + 7x^2 - 5x + 6 = 0 is:

(x^3(x - 5) + x(7x - 5) + 6) = 0

This equation can be solved by setting each factor equal to zero and solving for x:

x^3(x - 5) + x(7x - 5) + 6 = 0

(x^3 - 7x^2 + 5x) + (6 - 5x) = 0

x(x^2 - 7x + 5) - (5x - 6) = 0

x(x - 5)(x - 1) - (5x - 6) = 0

x(x - 5)(x - 1) = 5x - 6

x^3 - 6x^2 + 10x - 6 = 5x - 6

x^3 - 6x^2 + 5x = 0

x(x^2 - 6x + 5) = 0

x(x - 1)(x - 5) = 0

Therefore, the solutions to the equation x^4 - 5x^3 + 7x^2 - 5x + 6 = 0 are x = 0, x = 1, x = 5.

smith is in jail and has 3 dollars; he can get out on bail if he has 8 dollars. a guard agrees to make a series of bets with him. if smith bets a dollars, he wins a dollars with probability .4 and loses a dollars with probability .6. find the probability that he wins 8 dollars before losing all of his money if

Answers

Therefore, the probability that Smith wins 8 dollars before losing all of his money is approximately 0.0479.

To solve this problem, we can use a probability tree diagram to visualize the different possible outcomes.

At each stage, Smith either wins a dollars or loses a dollars, until he either reaches 8 dollars (and wins) or 0 dollars (and loses). We can calculate the probability of each outcome by multiplying the probabilities of the branches leading to that outcome.

Starting with 3 dollars, there are two possible outcomes:

Smith wins a dollar with probability 0.4, leaving him with 4 dollars.

Smith loses a dollar with probability 0.6, leaving him with 2 dollars.

From 4 dollars, there are three possible outcomes:

Smith wins a dollar with probability 0.4, leaving him with 5 dollars.

Smith loses a dollar with probability 0.6, leaving him with 3 dollars.

Smith wins 4 dollars with probability 0.4 * 0.4 = 0.16, leaving him with 7 dollars.

From 5 dollars, there are two possible outcomes:

Smith wins a dollar with probability 0.4, leaving him with 6 dollars.

Smith wins 3 dollars with probability 0.4 * 0.4 = 0.16, leaving him with 8 dollars.

From 6 dollars, there are two possible outcomes:

Smith wins 2 dollars with probability 0.4 * 0.4 = 0.16, leaving him with 8 dollars.

Smith loses a dollar with probability 0.6, leaving him with 5 dollars.

From 7 dollars, there is one possible outcome:

Smith wins 1 dollar with probability 0.4, leaving him with 8 dollars.

Therefore, the probability that Smith wins 8 dollars before losing all of his money is the sum of the probabilities of the outcomes that lead to winning 8 dollars, which is:

0.4 * 0.6 * 0.4 * 0.4 + 0.4 * 0.6 * 0.4 * 0.6 * 0.4 + 0.4 * 0.6 * 0.4 * 0.4 * 0.6 * 0.16 + 0.4 * 0.6 * 0.4 * 0.4 * 0.4 * 0.4 * 0.16 = 0.047872

Substituting the given values, we get:

185 = [tex]69 + (203 - 69) * e^-k*1.5[/tex]

Taking the natural logarithm of both sides, we get:

ln(0.8657) = -1.5k

Solving for k, we get:

k ≈ 0.232

Therefore, the value of the decay constant is approximately 0.232.

To find the temperature of the water after 4.5 minutes, we can use Newton's Law of Cooling again, with t = 4.5:

Answers

It's important to note that without the actual data, I cannot provide a definitive assessment of the model's appropriateness. I recommend conducting the analysis with the provided dataset to draw accurate conclusions about the suitability of the linear regression model.

To develop an estimated regression equation and assess the appropriateness of a simple linear regression model, we need the specific data from the "productioncost" dataset. Since the data is not provided, I cannot perform the analysis or construct the standardized residual plot.

However, I can provide you with a general approach to determine the appropriateness of a simple linear regression model based on a standardized residual plot. After fitting the regression model, you can calculate the standardized residuals by dividing the residuals by their estimated standard deviation. Plotting these standardized residuals against the predicted values can help assess the model's appropriateness.

In a standardized residual plot, if the residuals exhibit random scatter around the horizontal line at zero, with no discernible patterns or trends, it suggests that the linear regression model is appropriate. On the other hand, if there are systematic patterns or trends in the residuals, such as a curved shape or unequal spread, it indicates that the linear regression model may not adequately capture the relationship between the variables.

Answers

The value of the excretion is equal to 15 / 16 inches of precipitation per hour.

How to find the value of the excretion

In this question we find that a precipitation of 5 / 8 inches of rain is registered in a time of 2 / 3 hour and we are asked to find how many precipitation is registered in a time of an hour, that is, the value of the excretion. The excretion can be found by cross multiplication:

r = (5 / 8 in) / (2 / 3 h)

r = 15 / 16 in / h

A precipitation of 15 / 16 inches in a time of an hour is the value of the excretion.

Calculate the length of AC to 1 decimal place

Answers

The length of AC by the given data is about 11.0 cm.

We are given that;

ABCD is a trapezium AB=16cm, AD=11cm, BC=4cm

Now,

We can use these values to find DC. Since ABCD is a trapezium, we know that AB and DC are parallel. Therefore, the distance between them is constant. We can write:

AB−BC=AD−DC

Plugging in the given values, we get:

16−4=11−DC

Solving for DC, we get:

DC=11−12=−1

We can ignore the negative sign since we are only interested in the length of DC. So, DC = 1 cm.

Now we can plug in AD = 11 cm and DC = 1 cm into the Pythagorean theorem and get:

AC2=112+12

AC2=122

Taking the square root of both sides, we get:

AC=122​≈11.045

Rounding to one decimal place, we get:

AC≈11.0 cm

Therefore, by algebra the answer will be 11.0 cm.

two people leave their shared apartment at the same time. during a 500 second interval, one jogs 10 blocks south at a constant rate, whereas the second walks 5 blocks west, again, at a constant rate. what is their speed relative to each other during this interval? assume each block corresponds to 100 meters.

Answers

The relative speed between the jogger and the walker during the 500 second interval is 2.24 m/s.

To solve this problem, we need to first find the distances traveled by each person.

The jogger travels 10 blocks x 100 meters/block = 1000 meters south.

The walker travels 5 blocks x 100 meters/block = 500 meters west.

Using the Pythagorean theorem, we can find the distance between them: √((1000m)² + (500m)²) = 1118.03 meters.

To find their relative speed, we divide this distance by the time interval: 1118.03 meters / 500 seconds = 2.24 m/s.

Therefore, their speed relative to each other during this interval is 2.24 m/s.

The jogger traveled 1000 meters south, while the walker traveled 500 meters west. Using the Pythagorean theorem, the distance between them is 1118.03 meters. Dividing this distance by the time interval of 500 seconds, we get their relative speed, which is 2.24 m/s.

: The relative speed between the jogger and the walker during the 500 second interval is 2.24 m/s.

A person who owns a 2/3 of a land sells 1/4 of it express the land sold as a fraction of the whole land

Answers

If a person owns 2/3 of a land and sells 1/4 of it, the fraction of the whole land sold can be expressed as 1/4 divided by 2/3.

To divide fractions, we invert the second fraction and multiply. Therefore, we have:

1/4 ÷ 2/3 = 1/4 × 3/2 = 3/8

So, the fraction of the whole land sold is 3/8. This means that the person has 2/3 - 3/8 = 5/24 of the original land remaining after selling 1/4 of it.

To see why this is the case, we can visualize the original land as a pie chart. If the person owns 2/3 of the land, then 1/3 of the land belongs to someone else. If the person sells 1/4 of their share, they are effectively selling 1/4 of 2/3 of the land, or 2/12 of the land. This represents a portion of the pie chart that is 2/12 of the total pie, or 1/6. Therefore, the person now owns 5/6 of the pie chart, or 5/24 of the original land.

TANK A large tank is currently holding 12,000 gallons of water. The water will drain at a constant rate of 100 gallons per minute until the volume of water in the tank is 4,000 gallons. Write an equation to find the number of minutes m it will take for the specified amount of water to drain.

Answers

The equation to find the number of minutes m is 12000 - 100m = 4000

Writing an equation to find the number of minutes m

From the question, we have the following parameters that can be used in our computation:

Initial volume  = 12000 gallons

Rate of draining = 100 gallons per minute

Final volume of water = 4000 gallons

The equation to find the number of minutes m is represented as

f(m) = Initial volume - Rate of draining * m

So, we have

f(m) = 12000 - 100m

When the volume is at 4000 gallons, we have

12000 - 100m = 4000

Hence, the equation to find the number of minutes m is 12000 - 100m = 4000
