Volume of a cylinder with polynomials radius is x+3 and height is x+11

Answer:

y = 130 + 75x

My answer is based on the understanding that y is the charge for the service call, x is the number of hours spent on the service call and 130 is the base charge for the service.

Therefore, the 130 dollars is the baseline cost, as it is the charge even if 0 hours are spent. The extra 75 dollars per hour is the additional charge that has to be paid for every each hour that is spent on the job.

Therefore, the equation should be y = 130 + 75x.

The solutions of the differential equation y" - 6y' + 8y = 0 are [tex]y=3e^{2x}[/tex]

and [tex]y = Ce^{4x}[/tex]. So option D II and III only is correct.

A differential equation is an equation including dependent variables and their derivatives concerning independent variables.

Given the equation is y" - 6y' + 8y = 0. This can be written as [tex]\frac{d^2y}{dx^2}-6\frac{dy}{dx}+8y=0[/tex].

Now, let's substitute d/dx = m, and we get,

[tex]\begin{aligned}(m^2-6m+8)y&=0\\m^2-6m+8&=0\\m^2-(4+2)m+8&=0\\m^2-4m-2m+8&=0\\m(m-4)-2(m-4)&=0\\(m-4)(m-2)&=0\\m&=2,4\end{aligned}[/tex]

Then, the general solution will be written as [tex]y(x)=C_1e^{2x}+C_2e^{4x}[/tex]. Then, [tex]y_1=C_1e^{2x}[/tex] and [tex]y_2=C_2e^{4x}[/tex]. Hence, the solution of a given ODE is always this y₁ or y₂ or the combination of these. Therefore, (I) cannot be possible.

Now let's consider (II) and put [tex]y'=6e^{2x}[/tex] and [tex]y"=12e^{2x}[/tex] in the given equation. We get,

[tex]\begin{aligned}12e^{2x}-36e^{2x}+24e^{2x}&=0\\36e^{2x}-36e^{2x}&=0\\0&=0\end{aligned}[/tex]

Hence, (II) is the solution of the given equation and is possible.

Now let's consider (III) and put C₁=0 and we get, [tex]y(x)=C_2e^{4x}=Ce^{4x}[/tex]when C₂=C. Hence, (III) is possible.

Therefore, the correct option is D II and III only.

The complete question is -

Of the following, which are solutions to the differential equation y" - 6y' +8y=0?

I. y = 2 sin(4x)

II. [tex]y=3e^{2x}[/tex]

III. [tex]y = Ce^{4x}[/tex], where C is a constant.

A) I only B) Il only C) Ill only D) II and III only

It should be noted that point C is located at (2.6, 1.8).

The length of horizontal side = (xB − xA) = 4 units

length of vertical side = (yB − yA) = 2 units

To find the x-coordinate of the point that divides the horizontal side in the ratio 2 : 3, first convert the ratio between the parts into the fraction of the sum that the first part is equal to:    a/a+b= 2/2+3= 2/5

Multiply the length of the horizontal side by the fraction, and then add the result to the x-coordinate of point A:  Xc= Xa  + (a/a+b) (Xb - Xa) = 1+ (2/5 x 4) = 2.6

Multiply the length of the vertical side by the fraction, and then add the result to the y-coordinate of point A:  Yc= Ya  + (a/a+b) (Yb - Ya) = 1+ (2/5 x 2) = 1.8

It follows that point C is located at (2.6, 1.8).

Gauss-Jordan elimination is a method used to solve a system of linear equations by reducing the augmented matrix of the system to a reduced row-echelon form through a series of elementary row operations.

The process involves manipulating the rows of the augmented matrix to obtain a triangular matrix, where all entries below the diagonal are zero. This is achieved by applying elementary row operations such as adding a multiple of one row to another row or multiplying a row by a scalar.

Once the augmented matrix is in triangular form, further elementary row operations are used to eliminate the nonzero entries above the diagonal. This results in the augmented matrix being in reduced row-echelon form, where the pivot elements are all equal to 1 and the columns corresponding to the pivot elements are linearly independent.

It would  51.35 minutes take a puddle of water to freeze.

What is the initial temperature?

Initial temperature refers to the average interior temperature of the coldest processing container at the start of the thermal processing cycle, as determined after a thorough stir or shake of the filled and sealed container.

The given equation is T = R + (T₀ − R)[tex]e^{(-kt)}[/tex].

T = temperature of the object after t minutes

T₀ = initial temperature

R = temperature of the surroundings

k = cooling rate (depends on the object and conditions)

The initial temperature is 55°F. The water freezes at 32°F. Thus final temperature is 32°F. The value of k is 0.012.

Now putting T = 32°F, T₀ = 55°F, R = 5°F, k = 0.012 in the given equation:

32 = 5 + (55 − 5)[tex]e^{(-0.012t)}[/tex]

Subtract 5 from both sides:

27 = 50[tex]e^{(-0.012t)}[/tex]

Divide both sides by 50:

[tex]e^{(-0.012t)}[/tex] = 27/50

Taking natural logarithms on both sides:

ln[tex]e^{(-0.012t)}[/tex] = ln(27/50)

-0.012t = -0.616

where Nt is expected population size after t generations,

N0 is the initial population size, and lemda (λ) is the geometric growth rate.

Here, initial population size is N0 = 150, and the growth rate is λ = 1.2. We want to find the expected population size after two generations, so t = 2.

Putting these values into the formula, we get:

Philippa can buy 12 packs of mini jam jars, 9 packs of lids, and 4 packs of labels without having any items left over.

To find the smallest number of packs of each item Philippa can buy without having any items left over, we need to find the least common multiple (LCM) of 12, 16, and 36. The LCM is the smallest number that is a multiple of all three numbers.

We can find the LCM by listing the multiples of each number and finding the smallest number that appears in all three lists:

Multiples of 12: 12, 24, 36, 48, 60, 72, 84, 96, 108, 120, 132, 144...

Multiples of 16: 16, 32, 48, 64, 80, 96, 112, 128, 144...

Multiples of 36: 36, 72, 108, 144...

The smallest number that appears in all three lists is 144. Therefore, the LCM of 12, 16, and 36 is 144.

To find the smallest number of packs of each item Philippa can buy, we need to divide the LCM by the number of items in each pack:

Packs of mini jam jars: 144 ÷ 12 = 12

Packs of lids: 144 ÷ 16 = 9

Answer:

The correct answer is B. 200 and 100. When y is inversely proportional to x, it means that the ratio of x to y remains constant. In this case, when x = 20, y = 400, which means that the ratio of x to y is 20/400. Since the ratio is constant, we can use that ratio to find the values of y when x = 40 and x = 80. When x = 40, y = (20/400) x 40 = 200 and when x = 80, y = (20/400) x 80 = 100.

In general, if the sample size is large, adding an extremely large outlier to a data set will not substantially affect sample mean. The correct option is (b) sample mean

The sample size is large, adding an extremely large outlier to a data set will not substantially affect the sample mean.

This is because the sample mean is a measure of central tendency that is influenced by all the values in the dataset, but it is more affected by the values that are closer to it in magnitude. When the sample size is large, the impact of any individual outlier on the overall mean is typically reduced, as the outlier will be more likely to be balanced out by the other values in the dataset.

However, the addition of an extremely large outlier may still have an impact on the sample standard deviation and median, depending on the magnitude and distribution of the other values in the dataset.

Therefore, the correct option is (b) sample mean

Answer:

y^2 - 5y = 750

Step-by-step explanation:

If length = y

then width = y - 5

Area = length x width

= y(y-5) = 750

Or, y^2 - 5y = 750

This equation can be further solved as follows:

y^2 - 5y - 750 = 0

Or, y^2 - 30y + 25y - 750 = 0

Or, y(y - 30) + 25(y - 30) = 0

Or, (y + 25)(y-30) = 0

So, there are two possibilities:

If (y + 25) = 0

then y = -25

but value of length cannot be negative,

Let us look at second possibility

If (y - 30) = 0

then y = 30

So, length = 30 feet

Check Answer:

Length = 30 feet

so, width = 30 - 5 = 25 feet

so, area  = 30 x 25 = 750 square feet
