Find the absolute maximum value on​ (0, [infinity]​) forf(x)=4x−2xlnx.

Answers

Answer 1

The absolute maximum value on (0, ∞) for f(x) = 4x - 2x ln x is approximately 2e (5.436), which occurs at x = e.

To find the absolute maximum value on (0, ∞) for the function f(x) = 4x - 2x ln x, we need to follow these steps:
1. Determine the critical points of the function by finding its first derivative and setting it equal to zero.
2. Check the critical points for the maximum value.
3. Verify the behavior at the boundary of the interval (0, ∞).

Step 1: Find the first derivative of f(x).
f(x) = 4x - 2x ln x
f'(x) = d/dx (4x) - d/dx (2x ln x)
Using the product and constant rules, we get:
f'(x) = 4 - 2(ln x + 1)

Step 2: Set the first derivative equal to zero to find the critical points.
4 - 2(ln x + 1) = 0
2(ln x + 1) = 4
ln x + 1 = 2
ln x = 1
Solving for x:
x = e^1
x = e (approximately 2.718)

Step 3: Check the behavior at the boundaries.
As x approaches 0 from the right, ln x approaches negative infinity, making the term -2x ln x approach infinity. Since the interval is (0, ∞), we only need to consider the behavior as x approaches ∞. As x goes to infinity, both 4x and -2x ln x will also go to infinity. However, -2x ln x will increase at a slower rate compared to 4x, so f(x) will approach infinity.

Now, we need to check the value of f(x) at the critical point x = e:
f(e) = 4e - 2e ln e
f(e) = 4e - 2e(1)
f(e) = 2e (approximately 5.436)

Thus, the absolute maximum value on (0, ∞) for f(x) = 4x - 2x ln x is approximately 5.436, which occurs at x = e.

COMPARE BY USING <,>,=,<=,>=

Answers

The product of the middle two sums is greater than or equal to the product of the least and the greatest of the sums.

How can the two products be compared?

To compare two products, we need to compare the values of the products using the comparison operators (<, >, <=, >=, or =).

We can start by finding the sums of the original numbers (0, 1, 2, 3):

Sum of the original numbers = 0 + 1 + 2 + 3 = 6

Now, we add the number k to each of the numbers:

Sum of the new numbers = (0 + k) + (1 + k) + (2 + k) + (3 + k)

= (0 + 1 + 2 + 3) + 4k

= 6 + 4k

So, the new sums range from 6 + 4k (the smallest) to 9 + 4k (the largest).

The product of the least and the greatest of the sums is:

(6 + 4k) × (9 + 4k) = 54 + 60k + 16k^2

The product of the middle two sums is:

(7 + 4k) × (8 + 4k) = 56 + 60k + 16k^2

Comparing the two products using the comparison operators:

54 + 60k + 16k^2 < 56 + 60k + 16k^2 (since 54 < 56)

or

54 + 60k + 16k^2 <= 56 + 60k + 16k^2 (since the products are equal when k=0)

In conclusion, the product of the middle two sums is greater than or equal to the product of the least and the greatest of the sums.

Answers

(a) To find the curl of the vector field F(x, y, z), we first find its component functions:

F(x, y, z) = (5ex sin(y), 9ey sin(z), 2ez sin(x))

Then, we use the formula for the curl of a vector field:

curl F = (∂Fz/∂y - ∂Fy/∂z, ∂Fx/∂z - ∂Fz/∂x, ∂Fy/∂x - ∂Fx/∂y)

Plugging in the component functions of F(x, y, z), we get:

curl F = (2ez cos(x), -5ex cos(y), 9ey cos(z))

(b) To find the divergence of the vector field F(x, y, z), we use the formula for the divergence of a vector field:

div F = ∂Fx/∂x + ∂Fy/∂y + ∂Fz/∂z

Plugging in the component functions of F(x, y, z), we get:

div F = 5e^x sin(y) + 9e^y sin(z) + 2e^z sin(x)
(a) To find the curl of the vector field F(x, y, z) = (5e^x sin(y), 9e^y sin(z), 2e^z sin(x)), we need to compute the cross product of the del operator (∇) and F:

curl F = ∇ x F

curl F = ( (∂/∂y)(2e^z sin(x)) - (∂/∂z)(9e^y sin(z)), (∂/∂z)(5e^x sin(y)) - (∂/∂x)(2e^z sin(x)), (∂/∂x)(9e^y sin(z)) - (∂/∂y)(5e^x sin(y)) )

After computing the partial derivatives, we get:

curl F = ( 0, 5e^x cos(y) - 2e^z cos(x), 9e^y cos(z) - 5e^x cos(y) )

(b) To find the divergence of the vector field F(x, y, z), we need to compute the dot product of the del operator (∇) and F:

div F = ∇ ⋅ F

div F = (∂/∂x)(5e^x sin(y)) + (∂/∂y)(9e^y sin(z)) + (∂/∂z)(2e^z sin(x))

After computing the partial derivatives, we get:

Subtract 1/4- 5/14 = type an integer or fraction

Answers

Answer:

-3/28

Step-by-step explanation:

In order to subtract fractions you first have to get a common denominator. The common denominator between 4 and 14 is 28 since 4(7) = 28 and 14(2) = 28. Then multiply the top and bottom of (1/4) by (7/7) and (5/14) by (2/2). This gives a common denominator and since you multiply by a fraction equal to 1, it doesn't change the value. Therefore, we get 7/28 - 10/28 = -3/28.

Answers

A compound inequality to show the distance from the boys home to the chief's camp is 5 < d < 8

How to explain the inequality

The distance from the boy's home to the school is 5km.

The distance from the boy's home to the market is 8km.

The chief's camp is closer to the boy's home than the market, but further than the school

The chief's camp is closer to the boy's home than the market, so the distance from the boy's home to the chief's camp is less than 8km.

A: $43. 07


B: $39. 95


C: $45. 49


D: $60. 65

Answers

The total cost after discount and tax is $46.28.

To find the total cost after the discount and tax, we need to first find the subtotal before tax.

Fred bought two pairs of jeans for $17.99 each, so the cost of the jeans is $17.99 x 2 = $35.98.

He also bought three shirts at $5.99 each, so the cost of the shirts is $5.99 x 3 = $17.97.

The pack of socks costs $3.

The subtotal before discount is $35.98 + $17.97 + $3 = $57.95.

With the 25% off coupon, Fred gets a discount of $57.95 x 0.25 = $14.49.

The new subtotal after discount is $57.95 - $14.49 = $43.46.

Finally, we need to add the 6.5% sales tax.

The sales tax is $43.46 x 0.065 = $2.82.

The total cost after discount and tax is $43.46 + $2.82 = $46.28.

Therefore, the closest answer is C: $45.49.

Answers

Answer:

Step-by-step explanation:

Step-by-step explanation:

let's assumed that

x = 1h of horseback

y = 1h of parasailing

3h of horseback = 3x

2h of parasailing = 2y

and

2h of horseback = 2x

3h of parasailing = 3y

if

3x + 2y = 192

2x + 3y = 213

to find y we have to remove the x

(3x + 2y = 192) × 2

(2x + 3y = 213) × 3

6x + 4y = 384

6x + 9y = 639

___________ -

-5y = -255

y = 51

substitute y to any equation to find x

3x + 2y = 192

3x + 2(51) = 192

3x + 102 = 192

3x = 192 - 102

3x = 90

x = 30

so the answers are 1h of horseback = $30 and 1h of parasailing = $51

Rule 1:

If all three angles of the triangle are given and they all add up to exactly 180°, it is possible to get more than one triangle.  In the third option, we are given angles 62°, 36°, and 82°, so different triangles can be constructed. Also, they all add up to give 180°. The condition is satisfied.

Answers

The measure of the trade places with any opponent region is 30°

Let the measure of the trade places with any opponent = x

Move two space is twice the angle as trade places with any opponent

Move two space = 2x

Move one space is three times the angle as moving two spaces

Move one space = 3(2x)

Move one space = 6x

Lose your turn is a quarter

Lose your turn = 90°

The sum of a complete angle = 360°

90 + x + 2x + 6x = 360°

Answers

A data set has many very large data values, then the mean will be larger than the median. The correct option is a.

In a dataset with large values, the mean is influenced by outliers and extreme values, whereas the median is not. The median is the value that divides the data into two equal halves, while the mean is calculated by summing up all values and dividing by the total number of values.

Thus, in a skewed dataset with large values, the mean tends to be pulled towards the larger values, resulting in a larger mean than the median. This effect is more pronounced in datasets with a high variance. Therefore, option (a) is the correct answer.

Esteban decides to run a simulation using `3` coins, where heads represent the eyes changing color.






The table shows the results of his simulation.






Estimate the probability that at least one of Esteban’s kittens will still have blue eyes at three months old

Answers

There is an estimated probability of 0.875 (or 87.5%) that at least one of Esteban's kittens will still have blue eyes at three months old.

Let's use the complement rule to estimate the probability that at least one kitten will still have blue eyes at three months old:

P(at least one kitten with blue eyes) = 1 - P(no kitten with blue eyes)

To estimate P(no kitten with blue eyes), we can use the results of Esteban's simulation. We can see from the table that all three coins came up tails (representing no color change) in row 8, so that's one outcome where no kitten has blue eyes. There are a total of 2^3 = 8 possible outcomes, so the estimated probability of no kitten having blue eyes is:

P(no kitten with blue eyes) = 1/8 = 0.125

Therefore, the estimated probability that at least one kitten will still have blue eyes at three months old is:

P(at least one kitten with blue eyes) = 1 - P(no kitten with blue eyes) = 1 - 0.125 = 0.875

So, there is an estimated probability of 0.875 (or 87.5%) that at least one of Esteban's kittens will still have blue eyes at three months old.

There are infinitely many solutions to this equation. For example, one possible solution is a = 2, b = 0. Another possible solution is a = 1, b = 2.

How to find the area?

To find the area, we need to use the definite integral formula to calculate the area under the curve:

∫[0,4] f(x) dx = ∫[0,4] (ax + b) dx = 1/2 * a * x² + b * x |[0,4]

Substituting the limits of integration, we get:

1/2 * a * 4² + b * 4 - (1/2 * a * 0² + b * 0) = 16

Simplifying, we get:

8a + 4b = 16

Dividing by 4, we get:

2a + b = 4

Since (a,b) ≠ (0,0), there are infinitely many solutions to this equation. For example, one possible solution is a = 2, b = 0. Another possible solution is a = 1, b = 2.

Find the value of X of the circle

Answers

The circle's x value will continue to be the same as the arc ST. So, x has a value of 40 degrees.

What is circle?

A circle's centre is the point from which all of the distances to the other points on the circle are equal. The radius of the circle is the measurement at issue.

Every point on a circle is a geometric shape that is equally separated from the centre.

The location of any point that is evenly separated from the fixed point known as the circle's centre can also be characterised as it.

The distance from any point on a circle to the centre is known as the radius of the circle.

1. A washer and a dryer cost $1004 combined. The washer costs $54 more than the dryer. What is the cost of the dryer?

Please use your work.

Answers

The calculated cost of the dryer is $475.

What is the cost of the dryer?

Let's assume that the cost of the dryer is x dollars.

According to the problem, the cost of the washer is $54 more than the dryer.

Therefore, the cost of the washer is (x + $54).

We are given that the combined cost of the washer and the dryer is $1004. So we can set up the equation:

x + (x + $54) = $1004

Simplifying the equation:

2x + $54 = $1004

2x = $950

x = $475

Therefore, the cost of the dryer is $475.

And 7/8 hours Greg reads 2/3 chapters. What is the unit rate in chapters per hour? Write your answer in simplest form

Answers

The unit rate for chapters per hour is calculated as 16/21

How to find the unit rate

In order to find the unit rate for the number of chapters Gregory reads in an hour, we must firstly divide the total amount of chapters read by the amount of hours devoted to the activity:

= 2/3 chapters ÷ 7/8 hours

= 2/3 chapters × 8/7 hours

= 16/21 chapters per hour

Consequently, the unit rate for chapters per hour is calculated as 16/21, which already exists in its most simplified form.

The function h is given by h(x)=log_2(x^2 -6). For what positive value of x does h(x)=4?

Answers

The function h is given by h(x)=log2(x² -6). The positive value of x that makes h(x) equal to 4 is approximately 4.69

We have the function:

h(x) = log2(x² - 6)

We want to find the value of x that makes h(x) equal to 4:

h(x) = 4

log2(x² - 6) = 4

We can rewrite this equation as:

2⁴ = x² - 6

16 = x² - 6

x²= 22

x = √22 (because we are looking for a positive value of x)

Therefore, the positive value of x that makes h(x) equal to 4 is approximately 4.69 (rounded to two decimal places).
