how do you simplify this expression.

Answer:

the answer is D (4,3)

Step-by-step explanation:

The value of the integral ∫ ln(x)/x dx is  ln²(x)/2 + c

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

S lnx/x dx

Express properly

So, we have

∫ ln(x)/x dx

The above expression can be integrated using substitution method

Let u = ln(x)

So, we have

du/dx = 1/x

Make dx the subject

du = dx/x

So, we have

∫ u du

Apply the power rule to integrate

∫ u du = u²/2

Substitute u = ln(x)

When integrated, we have

∫ ln(x)/x dx = ln²(x)/2 + c

Where c is a constant

Hence, the value of the integral is ln²(x)/2 + c

The solutions of the equation 2x² = 18 are x = 3 and x = -3.

To find the solutions of the equation 2x² = 18, we need to solve for x.

We can start by dividing both sides of the equation by 2, which gives us x² = 9.

Next, we can take the square root of both sides to find the solutions. The square root of 9 is 3, so the solutions are x = 3 and x = -3.

The equation 2x² = 18 has two solutions, x = 3 and x = -3, which can be determined both algebraically and graphically by observing the points where the parabola f(x) = 2x² - 18 intersects the x-axis.

The solutions of the equation 2x² = 18 can be found by first dividing both sides of the equation by 2, which simplifies to x² = 9. This is a standard quadratic equation which can be further solved by taking the square root of both sides. The solutions are x = 3 and x = -3. If we graph the related function, which is f(x) = 2x² - 18, we will see a parabola opening upwards with its vertex at the origin (0,0), and it will intersect the x-axis at the points (3,0) and (-3,0), representing our solutions.

To use a graph of the related function, we can plot the equation 2x² - 18 = 0 on a graph and find the x-values where the graph intersects the x-axis. These x-values correspond to the solutions of the equation.

Answer: She Is Not Correct The Answer Is 24

Step-by-step explanation: The answer is 24. This is because when you have order of operations, you always do parentheses first. (27-9) equals 18. Then multiply it by 3 so do 20 times 3 and then subtract 6 and you get 54. Then divide 54 by 9 and you get 6. 6+18 does not equal 42 so it would be the third one.

-HAVE A GREAT DAY-

Answer:

the answer is C.

Step-by-step explanation:

using pemdas you start with parenthesis,

(27-9)*3÷9+18=42

18*3÷9+18=42 .         use rules of multiplication and division

54÷9+18=42             divide again

6+18=42                  add

24=42

this is false because the numbers don't match up on the left and right side, so 24 is the real answer.

Step-by-step explanation:

Answer:

The vertices feasible region are (0 , 15) , (10 , 15) , (20 , 5)

The minimum value of the objective function C is 125

Step-by-step explanation:

* Lets look to the graph to answer the question

- There are 3 inequalities

# y ≤ 15 represented by horizontal line (purple line) and cut the

  y-axis at point (0 , 15)

# x + y ≤ 25 represented by a line (green line) and intersected the

  x-axis at point (25 , 0) and the y- axis at point (0 , 25)

# x + 2y ≥ 30 represented by a line (blue line) and intersected the

  x-axis at point (30 , 0) and the y-axis at point (0 , 15)

- The three lines intersect each other in three points

# The blue and purple lines intersected in point (0 , 15)

# The green and the purple lines intersected in point (10 , 15)

# The green and the blue lines intersected in point (20 , 5)

- The three lines bounded the feasible region

∴ The vertices feasible region are (0 , 15) , (10 , 15) , (20 , 5)

- To find the minimum value of the objective function C = 4x + 9y,

  substitute the three vertices of the feasible region in C and chose

  the least answer

∵ C = 4x + 9y

- Use point (0 , 15)

∴ C = 4(0) + 9(15) = 0 + 135 = 135

- Use point (10 , 15)

∴ C = 4(10) + 9(15) = 40 + 135 = 175

- Use point (20 , 5)

∴ C = 4(40) + 9(5) = 80 + 45 = 125

- From all answers the least value is 125

∴ The minimum value of the objective function C is 125

The vertices of the feasible region are (0, 15), (10, 15), and (20, 5). The minimum value of the objective function C = 4x + 9y is 190 at the vertex (10, 15).

The feasible region is the area on a graph where all the constraints of a system of inequalities are satisfied. To find the vertices of the feasible region, we need to find the intersection points of the lines formed by the given constraints. By solving the system of equations, we find that the vertices of the feasible region are (0, 15), (10, 15), and (20, 5).

To find the minimum value of the objective function C = 4x + 9y, we substitute the x and y values of each vertex into the objective function and determine which vertex gives the smallest value. By evaluating the objective function at each vertex, we find that the minimum value is obtained at the vertex (10, 15) with a value of 4(10) + 9(15) = 190.

Here  the digits 1, 2, and 3 represent a van with check engine light that turn on.

Approximately how many vans will have check engine lights come on?

From the above given data the digits 1, 2 and 3 that represented the particular model of van having check engine lights on are repeated 7 times in the simulation of randomly checking 25 vans, with over 100,000 miles

Hence 7 vans will have check engine lights come on!

In a simulation using the provided set of digits, we find that out of 25 vans, approximately 6 have check engine lights that turn on.

To solve this problem, we'd first identify all the digits that are either 1, 2, or 3 within the provided sequence of randomly generated digits. These digits, according to your problem, represent vans with check engine lights that turn on. The string you provided is 96408, 03766, 36932, 41651, and 08410.

Upon counting, the following digits in the string are 1, 2, or 3: '3', '2', '3', '1', '1', and '1'. This gives us a total of 6 occurrences.

Therefore, based on this simulation, if we were to randomly check 25 vans with over 100,000 miles, approximately 6 of them would have check engine lights that come on.

If P(3) stands for the probability of the number 3 getting rolled, since 3 was rolled 5 times (as shown on the graph) out of 50 (as mentioned in the question), the experimental probability would be: 5/50, which when simplified, is 1/10

The student is asked to calculate the experimental probability of rolling a 3, but the specific frequency Sarah rolled a 3 is not provided. Without this, we cannot compute the experimental probability. Generally, the method involves dividing the number of times a 3 was rolled by the total number of rolls.

The question asks for the experimental probability of rolling a 3 on a six-sided die based on the results Sarah obtained from her 50 rolls. However, the provided information does not include the actual frequency of rolling a 3 in her experiment. If we had that data, the experimental probability P(3) would be the number of times a 3 was rolled divided by the total number of rolls (50 in Sarah's case).

For example, if Sarah rolled a 3 ten times out of 50, then the experimental probability of rolling a 3 would be calculated as follows: P(3) = 10/50 = 1/5. Without the specific results of Sarah's rolls, we cannot determine the experimental probability from the information given in the question.

Final answer:

Rebecca can divide ¾ of a cake into 9 pieces by finding the fraction of each piece relative to the whole cake, which is ⅛ or one-twelfth of the whole cake.

Explanation:

How to Divide a Cake into Equal Pieces

To divide ¾ of a cake into 9 equal pieces, Rebecca must consider how many pieces the whole cake can be divided into first. Since she has three-quarters of a cake, and she wants to make 9 pieces out of it, each piece will be one-ninth of the three-quarters of a cake. To find out the size of each piece relative to the whole cake, she divides ¾ by 9. This can be calculated as ¾ × ⅟, which simplifies to ⅛. This means that each piece of cake will be one-twelfth of the whole cake.

Understanding fractions such as halves, thirds, and quarters is useful in daily life and in solving problems like these. Knowing that a quarter is 25 cents makes it easier to grasp a quarter of a pie or cake. If you can visualize that two-thirds of a pie is more than half a pie, it helps when dividing portions or budgeting resources.

For this case we have that by definition, the density is given by:

ρ =[tex]\frac {M} {V}[/tex]

Where:

M: It's the mass

The volume of a solid cone is given by:

[tex]V = \frac {1} {3} \pi * r ^ 2 * h[/tex]

Where:

A: It's the radio

h: It's the height

Substituting the data we have:

 [tex]V = \frac {1} {3} \pi * (4) ^ 2 * 21\\V = \frac {1} {3} \pi * 16 * 21\\V = 401.92 \ cm ^ 3[/tex]

On the other hand, we have that by definition, the density of the platini is given by:

[tex]21.45 \frac {g} {cm ^ 3}[/tex]

Substituting in the initial formula, we look for the mass:

[tex]M = 401.92 \ cm ^ 3 * 21.45 \frac {g} {cm ^ 3}\\M = 8621.184 \ g[/tex]

ANswer:

The mass of the platinum cone is 8621.2 grams.

To find the mass of a solid platinum cone with a height of 21 cm and a diameter of 8 cm, calculate the volume using the formula for a cone (⅓πr²h) and then multiply by platinum's density (21,450 kg/m³) to get approximately 30.342 kg.

Calculate the Mass of a Platinum Cone

To determine the mass of a solid cone made of platinum with a given height and diameter, we must first calculate its volume and then use the density of platinum to find its mass. The density of platinum is approximately 21,450 kg/m³. The volume of a cone is given by the formula ⅓πr²h, where r is the radius and h is the height. For our cone with a height (h) of 21 cm and a diameter of 8 cm, the radius (r) would be half of the diameter, so r = 4 cm = 0.04 m. Plugging the values into the formula, we get:

Volume (V) = ⅓π(0.04 m)²×21 cm = ⅓π(0.0016 m²)× 0.21 m = 0.0014136 m³.

To find the mass (m), we multiply the volume by the density of platinum (ρ):

Mass (m) = Density (ρ) × Volume (V) = 21,450 kg/m³ × 0.0014136 m³ = 30.342 kg.

Therefore, the mass of the solid platinum cone is approximately 30.342 kilograms.

Answer:

Discount Rate=17%

Step-by-step explanation:

We know the price and discount of the car. The formula for calculating the discount when rate is given is:

[tex]Discount=Listed\ price*discount\ rate[/tex]

We know two quantities out of three, so putting in the known values:

[tex]3000=18000*rate\\rate=\frac{3000}{18000}\\Rate=16.67%[/tex]

The rate rounded off to nearest percent will give us:

17 percent.

So the discount rate is 17% ..

When rounded to the nearest whole percent, the discount rate is 17%.

To calculate the rate of the discount for the Bucio family's new car purchase, we will use the formula for finding the percentage rate of a discount, which is:

Discount Rate = (Discount Amount / Original Price) x 100.

In their case, the car has an original list price of $18,000, and they are offered a discount of $3,000. Plugging these values into the formula gives us:

Discount Rate = ($3,000 / $18,000) x 100

Discount Rate = 0.1667 x 100

Discount Rate = 16.67%

When rounded to the nearest whole percent, the discount rate is 17%.

The frequency of a musical note is the inverse of its period. The period is the amount of time it takes for one complete cycle of the sound wave. If Adam Lopez's record-setting C8 has a period of 0.00024 seconds, we can calculate the frequency as follows:

To the nearest hertz, the frequency of the C8 note is 4167 hertz.

The correct answer is D. 4167 hertz.

1               2            16

------ + ------------ = ----------

h-5        h+5          (h-5)(h+5)

Since h^2 -25 factors in (h-5) (h+5)  ( it is the difference of squares)

We will multiply both sides by  (h-5) (h+5)  to clear the fractions

(h-5) (h+5)              2 (h-5) (h+5)            16 (h-5) (h+5)

------              + ------------                     = ----------

h-5                   h+5                                (h-5)(h+5)

Median is 50% of a data.

[tex]Q_3=70[/tex]

Q₃ is 75% of a data.

[tex]\text{Maximum values}=76[/tex]

34 is minimum value of the data and 46 is median it means 50% of the data values lies between 34 and 46. Therefore option 1 is correct.

42 is first quartile and and 70 is third quartile. it means 50% of the data values lies between 42 and 70. Therefore option 2 is incorrect.

The difference between Minimum value and first quartile, Maximum value and third quartile is less than 1.5×(IQR), therefore it is unlikely to have any outliers in the data.

Hence option 3 is correct.

The interquartile range of the data is
