Answer:

y = 5x + 28

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Here m = 5 , thus

y = 5x + c ← is the partial equation

To find c substitute (- 6, - 2) into the partial equation

- 2 = - 30 + c ⇒ c = - 2 + 30 = 28

y = 5x + 28 ← equation of line

If a = 3 and b = 5, find a/(a+b).

\( \bf \frac{a}{a + b} = \\ \\ \bf = \frac{3}{3 + 5} = \\ \\ \bf = \red { \boxed{ \bf \frac{3}{8}} } \)

So to find the missing side we can use the pythagorean formula to do this. It must be a right angle triangle if we want to use the formula. So we know two of the side lengths and that, that it has a right angle. Let's do it real quick! The formula is:

c^2=a^2+b^2 (c, the missing side, a is any side, b is the other side length)

So in this one we will find the missing side which is c . . . Place the formula!

c^2 = 7.7^2 + 7.7^2

c^2 = 59.29 + 59.29

c = square root of 118.58

c = 10.89 --> round to nearest tenth is 10.9

In Bach's Little Fugue, the main melody is typically repeated in a high part.

The high part is usually played by the trumpet or the violin, while the lower parts are played by other instruments like the bassoon, cello, or organ. A fugue is a musical composition where a single melody is introduced, repeated, and developed in different parts and voices. Bach's Little Fugue in G minor is one of the most famous fugues of all time and is an excellent example of this compositional technique. The fugue is typically played on an organ and features four voices, each with its own unique melody. The piece begins with the introduction of the subject, which is then repeated and developed in various parts throughout the composition. The repetition and development of the main melody are what make a fugue unique and interesting to listen to. In Bach's Little Fugue, the high trumpet or violin parts are where you can typically listen for the repetition of the main melody.

Answer:

The current price is Tk. 3750

Step-by-step explanation:

Given:

\(\%\ Increase = 20\%\)

\(New\ Price = Tk.\ 4500\)

Required

Determine the current price

Percentage increment is calculated using the following formula:

\(\%\ Increase = \frac{New - Old}{Old}\)

In this case, we have:

\(\%\ Increase = \frac{New\ Price - Old\ Price}{Old\ Price}\)

Substitute values for % increase and New Price

\(20\% = \frac{4500 - Old\ Price}{Old\ Price}\)

Cross Multiply

\(20\% *Old\ Price= 4500 - Old\ Price\)

Convert percentage to decimal

\(0.20*Old\ Price= 4500 - Old\ Price\)

Collect Like Terms

\(Old\ Price+0.20*Old\ Price= 4500\)

Factorize:

\(Old\ Price(1+0.20)= 4500\)

\(Old\ Price(1.20)= 4500\)

Solve for Old Price

\(Old\ Price= \frac{4500}{1.20}\)

\(Old\ Price= 3750\)

Hence, the current price is Tk. 3750

Answer:

\(\frac{4}{90}\)

Step-by-step explanation:

\(\frac{4}{9}\)  - \(\frac{4}{10}\)

to subtract the fractions we require them to have a common denominator

the LCM of 9 and 10 is 90

= = \(\frac{4(10)}{9(10)}\) - \(\frac{4(9)}{10(9)}\)

= \(\frac{40}{90}\) - \(\frac{36}{90}\)

= \(\frac{40-36}{90}\)

The volume of the solid obtained by rotating the region bounded by y = ln(x), y = 0, and x = 4 about the x-axis using the method of cylindrical shells.

To set up the integral for the volume of the solid obtained by rotating the region bounded by the curves y = ln(x), y = 0, and x = 4 about the x-axis using the method of cylindrical shells, we can follow these steps:

Draw a rough sketch of the region and the axis of rotation to visualize the shape of the solid.

Since we are using the method of cylindrical shells, we need to express the volume of each shell in terms of the radius and height. The radius of each shell is the distance from the x-axis to the curve y = ln(x), which is given by r = y. The height of each shell is the difference between the x-coordinates of the two bounding curves, which is h = 4 - x.

The integral for the volume of the solid is given by the sum of the volumes of all the cylindrical shells. We can express the volume of each shell as:

dV = 2πrh dx

where r = y and h = 4 - x.

The limits of integration for x are 0 to 4, since the region is bounded by the curves y = ln(x), y = 0, and x = 4. Therefore, the integral for the volume of the solid is:

V = ∫[0,4] 2πy(4-x) dx

Note that we are integrating with respect to x, since the shells are vertical and have a width of dx. However, we can express y in terms of x using the equation y = ln(x), which gives:

V = ∫[0,4] 2πln(x)(4-x) dx

This integral represents the volume of the solid obtained by rotating the region bounded by y = ln(x), y = 0, and x = 4 about the x-axis using the method of cylindrical shells.

Improvement in quality of service:

Putting the customer first, balancing efficiency and customer satisfaction (experience), and focusing on employee engagement are three key strategies for improving contact center service quality.

Productivity:

Productivity is the efficiency with which goods and services are produced and is represented by a scale. A measure of productivity is often expressed as a ratio of total output to a single input or total input in a production process. Typically the output per unit of input over a period of time. The most common example is a measure of (aggregate) labor productivity, an example of which is GDP per worker. There are various definitions of productivity (including those not defined by the ratio of outputs to inputs), and the choice depends on the purpose of measuring productivity and the availability of data gain. The main reason for differences in different measures of productivity usually has to do with how outputs and inputs are aggregated (directly or indirectly) to obtain such relative measures of productivity doing conduct.

Importance of Productivity:

Productivity gains are defined as the process of getting more out of every hour of work. Improving productivity can take many forms, including: Capital, Investments in equipment, software, infrastructure, machinery, etc. equate to labor.

Answer:

y = 1 + 2√7 or y = 1 - 2√7

Step-by-step explanation:

To complete the square, you need to add and subtract the square of half of the coefficient of the y term.

First, you can factor out a 1 from the y^2 - 2y term:

y^2 - 2y - 27 = 0

y^2 - 2y = 27

Next, take half of the coefficient of the y term (-2/2 = -1) and square it (1):

y^2 - 2y + 1 - 1 = 27

The "+1 -1" doesn't change the value of the equation, it's just a way to add 0 to the equation so we can complete the square.

Now you can rewrite the left side as a perfect square:

(y - 1)^2 - 28 = 0

Add 28 to both sides:

(y - 1)^2 = 28

Take the square root of both sides (remembering to include both positive and negative square roots):

y - 1 = ±√28

y = 1 ± 2√7

So the solutions are:

y = 1 + 2√7

y = 1 - 2√7

Answer: y=± 2√7+1

To determine whether the set S is linearly independent or linearly dependent.The set is linearly independent. This is because the only way to make a linear combination of vectors equal to the zero vector is to have all the coefficients equal to zero.

A linear combination of vectors is the sum of a scalar multiple of each vector in the set. We must check if the equation a(-2,2,4) + b(1,9,-2) + c(2,3,-3) = (0,0,0) has only the trivial solution, i.e., a=b=c=0. This gives us the system of equations,-2a + b + 2c = 01a + 9b + 3c = 02a - 2b - 3c = 0We can solve the system of equations by using Gauss-Jordan elimination. The augmented matrix for the system is:[-2 1 2 0][1 9 3 0][2 -2 -3 0]Let's use elementary row operations to simplify the matrix.

We can swap the first and second rows since the first element in the second row is 1.[1 9 3 0][-2 1 2 0][2 -2 -3 0]We can then add twice the first row to the third row to eliminate the leading coefficient in the third row.[1 9 3 0][-2 1 2 0][0 16 3 0]We can then add nine times the first row to the second row to eliminate the leading coefficient in the second row.[1 9 3 0][0 17 15 0][0 16 3 0]We can then add -16/17 times the second row to the third row to eliminate the leading coefficient in the third row.[1 9 3 0][0 17 15 0][0 0 -117/17 0]We see that the only solution is a=0, b=0, and c=0.

The expected value of the continuous random variable V is 5. The expected value of V is 5, indicating that, on average, we expect the value of V to be around 5.

To calculate the expected value of a continuous random variable V with a given probability density function (PDF), we integrate the product of V and the PDF over its entire range.

The PDF of V is defined as:

f(v) = 6/24 = 0.25 for 3 ≤ v ≤ 7, and 0 otherwise.

The expected value of V, denoted as E(V), can be calculated as:

E(V) = ∫v * f(v) dv

To find the expected value, we integrate v * f(v) over the range where the PDF is non-zero, which is 3 to 7.

E(V) = ∫v * (0.25) dv, with the limits of integration from 3 to 7.

E(V) = (0.25) * ∫v dv, with the limits of integration from 3 to 7.

E(V) = (0.25) * [(v^2) / 2] evaluated from 3 to 7.

E(V) = (0.25) * [(7^2 / 2) - (3^2 / 2)].

E(V) = (0.25) * [(49 / 2) - (9 / 2)].

E(V) = (0.25) * (40 / 2).

E(V) = (0.25) * 20.

E(V) = 5.

Therefore, the expected value of the continuous random variable V is 5.

The expected value represents the average value or mean of the random variable V. It is the weighted average of all possible values of V, with each value weighted by its corresponding probability. In this case, the expected value of V is 5, indicating that, on average, we expect the value of V to be around 5.
