The inverse Laplace transform of (2/(s+5)) is f(t) = 2 * e^(-5t)u(t).

To find the inverse Laplace transform of F(s) = (2/(s+5)), we can use partial fraction expansion and then use a table of Laplace transforms to identify the inverse transforms.

Step 1: Perform partial fraction expansion on the fraction:

(2/(s+5)) = (2/5) * (1/(1+(s/5))) = (2/5) * (1/1 + (s/5))

Step 2: Recognize the form of the partial fraction as a geometric series, and use the formula for the sum of a geometric series to find the inverse Laplace transform:

The sum of this geometric series is

(2/5) * (1/(1-(-s/5)))

= (2/5) * (1/(1+s/5))

= (2/5) * (5/5+s)

= (2/(5+s))

Step 3: Use the table of Laplace transforms to find the inverse transform of (2/(5+s)):

f(t) = 2 * e^(-5t)u(t)

where u(t) is the unit step function.

[tex]-\sqrt{9y^2} = -1\cdot \sqrt{9}\cdot \sqrt{y^2}[/tex]

I assume you're good with [tex]\sqrt{9}=3[/tex], so this gives us:

          [tex]= -3\cdot \sqrt{y^2}[/tex]

Now the trick on the variable portion is that since y<0, when you square y, you turn it from being a negative number into a positive [tex]y^2[/tex] value.  And when you take the square root of that, you keep the positive value.  So effectively, [tex]\sqrt{y^2} = |y|[/tex], since it just makes the negative number become positive.

The equation g(x) = (x - 4) (x + 2) is in the factored form.

The x-intercepts are x = -2 and x = 4.

The axis of symmetry is x = 1.

Vertex is (1, -9).

An equation is a mathematical statement that is made up of two expressions connected by an equal sign.

Example:

2x + 3 = 8 is an equation.

We have,

g(x) = (x - 4) (x + 2)

This is in the factored form.

Now,

From the graph,

The x-intercepts are x = -2 and x = 4.

The axis of symmetry.

x = -b/2a

x = 2/2

x = 1

i.e

g(x) = (x - 4) (x + 2)

g(x) = x² + 2x - 4x - 8

g(x) = x² - 2x - 8

a = 1, b = -2, and c = -8

Now,

g(x) = x² - 2x - 8

g(x) = x² - 2x + 1 - 1 - 8

g(x) = (x² - 2x + 1) - 9

g(x) = (x - 1)² - 9

This is in the form of f(x) = a(x - h)² + k

So,

Vertex = (h, k) = (1, -9)

The dimensions of width, length and height of the passenger section of the train are 3 meters, 13 meters and 3 meters respectively.

The volume of a rectangular prism is expressed as;

( 2x(2x) + 2x(3) - 7(2x) - 7(3) )( x - 2) = 117

( 4x² - 8x - 21 )( x - 2 ) = 117

Expand

4x³ - 16x² - 5x + 42 = 117

4x³ - 16x² - 5x + 42 - 117 = 0

4x³ - 16x² - 5x - 75 = 0

Using rational roots text

(x - 5)(4x² + 4x + 15 ) = 0

( x - 5 ) = 0

x - 5 = 0

x = 5

Inequalities are the mathematical expressions in which both sides are not equal. In inequality, unlike in equations, we compare two values. The equal sign in between is replaced by less than (or less than or equal to), greater than (or greater than or equal to), or not equal to sign.

Given equation of the line

Answer:

Step-by-step explanation: The above answer is only partially right.  Due to the fact that the line with the arrows is solid, the sign is greater than or equal to.

So, the side with (0,0) is the side where x+3y>−15 and the shaded region (which contains (0,0)) shows the solutions of the inequality x+3y>−15.

Notice that since the boundary line is graphed with a solid line, the inequality includes the equal sign.

The graph shows the inequality x+3y≥−15.

Probability has values between 0 and 1.

What is the Probability?

The probability of an event is a number between 0 and 1, where, roughly speaking, 0 indicates the impossibility of the event and 1 indicates certainty.

0 represents an impossible event and 1 represents a certain event.

A probability of 0 means that an event will not occur, and a probability of 1 means that an event will certainly occur.

Probabilities between 0 and 1 represent the likelihood of an event occurring, with values closer to 1 indicating a higher likelihood of the event occurring and values closer to 0 indicating a lower likelihood.

Hence, Probability has values between 0 and 1.

The number of terminating zero when the number 6311! is  multiplied out is 252

In mathematics, trailing zeros are a series of digits (usually 0) that follow a number's decimal form or, more broadly, any positional representation.

In mathematics, the term "factorial" refers to the product of all positive integers that are less than or equal to a certain positive integer, which is followed by an exclamation point.

Thus, factorial five is denoted by the symbol 5!, which stands for 1 * 2 * 3 * 4 * 5. Factorial 0 is equivalent to 1 by definition.

If you read the decimal version of 4.8 out loud, it should be "four and eight-tenths."  This will always give you a good place to start when changing a decimal into an equivalent fraction.

Now, this is a mixed number: 4 and 8/10. To further simplify it as a mixed number, we can leave the 4 alone and reduce the fraction (8/10).  Both the numerator and denominator are divisible by 2, so we can conclude (8/10) = (4/5).  A correct answer in mixed number form is 4 and (4/5).

However, to change 4 and (4/5) to a single (improper) fraction, you first multiply the denominator (5) by the large number out front on the left (4) and ADD this product to the numerator (4).  This number is your new numerator and it will still have the same denominator as before.

Here, 4 and (4/5) = [(5)*(4) + 4]/5 = (20+4)/5 = 24/5.

24 and 5 have no common factors, so this fraction is already in reduced form.

Youth unemployment rate change from April to July is 25%.

Youth labor force participation rate in July is 7.27%.

Rate of change is the speed at which the variables changes with respect to time.

From April to July​ 2015, the number of employed youth​ 16- to​ 24-years old rose by 2.1 million to 20.3 million

Youth unemployment increased from 2.1 million to 2.8 million.

In​ July, the youth labor force grew by 2.8 million to a total of 23.1 million.

Youth population was 38.5 million.

[tex]labor force rate =\frac{labor force}{adult population} *100[/tex]

                       = [tex]\frac{2.8}{38.5} *100[/tex] = 7.27%

[tex]unemployment rate = \frac{number of unemployment}{labor force} *100[/tex]

                              = [tex]\frac{2.8-2.1}{2.8} *100[/tex]=25%

(b) The number of people to be selected from those who responded "yes" in the stratified random sample is 14.

(c) A statistical advantage of using the stratified random sample instead of the simple random sample is that it ensures a proportional representation of each stratum (in this case, "yes" and "no" responses) in the sample, reducing the risk of bias and increasing the accuracy of the results.

The calculation is determined by dividing the total number of samples (20) by the number of strata (2) plus 1, then multiplying by the number of samples for each stratum. The result of 20 / (2 + 1) * 2 is

20 / 3 * 2

= 40 / 3

= approximately 13.33, which is rounded up to 14 people.

In a simple random sample, the individuals selected may not accurately reflect the proportions of the two responses in the population. This can result in incorrect conclusions and decision-making. With the stratified random sample, the proportions of "yes" and "no" responses in the sample are maintained, providing a more accurate representation of the population.

Additionally, stratified random sampling allows for separate analysis of each stratum, which can provide additional insights into the population. Overall, stratified random sampling is a more robust method for obtaining accurate and representative results in a survey setting.

Answer:

To calculate the value of X, we first need to calculate the total amount of money Miss Saver will have saved by the time she retires at age 60.

We know that her first payment is $1000, and that every subsequent payment increases by 5%. Using this information, we can calculate the total payments made during the 30 years:

$1000 x (1 + 0.05)^30 = $1000 x 3.3201 = $3320.1

This is the total amount of money Miss Saver will have saved by the time she retires at age 60.

Next, we need to calculate the value of each annual withdrawal over the 20 years of withdrawals.

We know that the effective annual interest rate is 2% perpetually, so we can use the formula for the future value of an annuity:

FV = X * ((1 + r)^n - 1) / r

where X is the annual withdrawal, r is the interest rate (0.02), and n is the number of years (20).

We can use this formula to solve for X:

3320.1 = X * ((1 + 0.02)^20 - 1) / 0.02

X = 3320.1 * 0.02 / (1.02^20 - 1)

X = 3320.1 * 0.02 / 0.1135 = $292.36

Therefore, Miss Saver needs to withdraw $292.36 each year for 20 years to deplete her savings account.

Rounded to the nearest integer, the value of X is $292.

The mean is the average of the data that is: ( $125,000,+$125,000+$178,000+$190,000+$216,000+$225,000+$890,000)/7 = 1949000/7 = 279429
