Find the inverse Laplace transform of (4+9s)/s^2
The inverse Laplace transform of of (4+9s)/s^2 is
The inverse Laplace transform of (4+9s)/s^2 is given by f(t) = 4t + 9, where f(t) represents the time-domain function.
To find the inverse Laplace transf
orm of (4+9s)/s^2, we can use the property that the inverse Laplace transform of a constant multiplied by a term of the form s^n is equal to t^(n-1)/((n-1)!).
In this case, we have (4+9s)/s^2, which can be rewritten as 4/s^2 + 9s/s^2. Applying the property mentioned above, we get the inverse Laplace transform of 4/s^2 as f₁(t) = 4t and the inverse Laplace transform of 9s/s^2 as f₂(t) = 9.
Therefore, the inverse Laplace transform of (4+9s)/s^2 is the sum of f₁(t) and f₂(t), which gives us f(t) = 4t + 9. Thus, the time-domain function is f(t) = 4t + 9.

The difference of the same side interior angles of two parrelels lines is 50 degrees find all angles
Answer:
Angle 1 = 115 degrees
Angle 2 = 65 degrees
Step-by-step explanation:
Angle 1: Same-side interior angle of Line 1
Angle 2: Same-side interior angle of Line 2
We know that the difference between the angles is 50 degrees. Since the angles are supplementary, we can write the equation:
Angle 1 + Angle 2 = 180
Now, we need to express the difference between the angles in terms of Angle 1 or Angle 2. We can choose either angle, so let's express it in terms of Angle 1:
Angle 1 - Angle 2 = 50
We can rewrite this equation as:
Angle 1 = 50 + Angle 2
Now substitute this expression for Angle 1 into the first equation:
(50 + Angle 2) + Angle 2 = 180
Combine like terms:
2Angle 2 + 50 = 180
Subtract 50 from both sides:
2Angle 2 = 130
Divide by 2:
Angle 2 = 65
Now substitute this value back into the equation for Angle 1:
Angle 1 = 50 + Angle 2
Angle 1 = 50 + 65
Angle 1 = 115
Therefore, the angles are as follows:
Angle 1 = 115 degrees
Angle 2 = 65 degrees
Given the functions

X=
Please hurry :)
Answer:
X = 5
Step-by-step explanation:
So what the equation is saying is that f(x) = g(x) so these equations are equal
The equation will look like this
125 + 15x = 12x + 140
I first began with subtracting the 12x from the 15x which will give you 3x
125 + 3x = 140
now we subtract 125 to 140 and you'll get 15
140-125 = 15 now divide by 3 leaving the x solo
15/3 = 5 so x is 5

sketch the graph of the probability density function over the indicated interval. f(x) = 1 10 , [0, 10]
The graph of the probability density function f(x) = 1/10 over the interval [0, 10] is a flat, horizontal line at y = 1/10.
The probability density function (PDF) f(x) = 1/10, defined over the interval [0, 10], represents a uniform distribution. In a uniform distribution, the probability of any value within the interval is constant, indicating that all values are equally likely to occur.
To sketch the graph of this PDF, we can plot the function f(x) = 1/10 on a coordinate plane.
First, we set up the axes. We label the x-axis to represent the interval [0, 10], where 0 is the lower limit and 10 is the upper limit. The y-axis represents the probability density.
Next, we plot the points on the graph. Since the PDF is a constant function, the value of f(x) = 1/10 for all x in the interval [0, 10]. Therefore, we mark a horizontal line at y = 1/10 across the entire interval.
The horizontal line represents a flat line parallel to the x-axis. The height of the line is 1/10, indicating that the probability density is constant throughout the interval [0, 10]. This means that any value within the interval has an equal probability of occurring.
The graph visually represents the uniform distribution, where the probability is evenly distributed across the entire interval.

The solution candidates y1(t)=A\(e^{(\alpha t)\)cos(βt) and y2(t)=B\(e^{(\alpha t)\)sin(βt) for a second-order linear differential equation with constant coefficients and complex roots r1,2=α±βi are not based on pure luck. They are derived using the fact that complex exponential functions can be written as a linear combination of real exponential functions and trigonometric functions through Euler's formula:
e^(α+βi)t = e^αt(cos(βt) + i sin(βt))
Taking the real and imaginary parts of this equation, we get:
e^(αt)cos(βt) = Re(e^(α+βi)t) and e^(αt)sin(βt) = Im(e^(α+βi)t)
So, the solutions y1(t) and y2(t) can be written as linear combinations of exponential functions and trigonometric functions.

Let X1, X2, ..., X100 be independent discrete random variables, each with probability mass function (pmf) p(x) = 1 x for x = 1, 2, 3,4. a. Use the central limit theorem to approximate P(3< Xi+X2+...+X 100 <3.2). 100 b. Use R to simulate the problem and estimate the probability in part (a). Then compare your answers to parts (a) and (b).
Comparing the results from parts (a) and (b) will allow us to assess the accuracy of the approximation made using the central limit theorem.
(a) To approximate the probability P(3 < Xi+X2+...+X100 < 3.2) using the central limit theorem, we can consider the sum of the random variables Xi+X2+...+X100 as a sample mean. Since the random variables Xi are independent and identically distributed, the sum follows a normal distribution as n (the number of variables) increases. We can calculate the mean and variance of the individual random variables, which are 2.5 and 1.25, respectively. Then, we can approximate the probability using the standard normal distribution by standardizing the values (subtracting the mean and dividing by the standard deviation).
(b) Using R, we can simulate the problem by generating a large number of random samples from the given distribution and calculating the proportion of samples that satisfy the condition 3 < Xi+X2+...+X100 < 3.2. By repeating this simulation multiple times, we can estimate the probability.

how to calculate the porbablitiy of something happening between two indepednent normallhy distributed things given mean and standard deviation
A standard normal distribution table, or a calculator with a built-in CDF function for the standard normal distribution to calculate this probability.
To calculate the probability of an event occurring between two independent normally distributed variables, we can use the standard normal distribution and the properties of linear combinations of normal variables.
Suppose we have two independent random variables X and Y that are normally distributed with means μX and μY, and standard deviations σX and σY, respectively. Let Z be a linear combination of X and Y given by Z = aX + bY, where a and b are constants.
Then, Z is also normally distributed with mean μZ = aμX + bμY and standard deviation σZ = sqrt(a^2 * σX^2 + b^2 * σY^2).
To calculate the probability of an event occurring between two values, say a and b, for the variable Z, we first standardize Z to a standard normal variable Z* using the formula:
Z* = (Z - μZ) / σZ
Then, we can use the cumulative distribution function (CDF) of the standard normal distribution to calculate the probability of the event occurring between a and b as:
P(a < Z < b) = P[(a - μZ) / σZ < Z* < (b - μZ) / σZ]
We can use statistical software, a standard normal distribution table, or a calculator with a built-in CDF function for the standard normal distribution to calculate this probability.

Angle 3 = 5x - 38
Find the measure of Angle 4
The measure of angle 4 is 133° and is equal to Angle 2 because there are corresponding angles formed by parallel lines cut by a transversal.
What are corresponding anglesCorresponding angles are the angles that are formed when two parallel lines are cut or intersected by the transversal and they are equal.
The angles 1, 2, 3 and 4 all lie on a transversal line that cuts the parallel lines, hence angles 1 and 3 are corresponding angles are they are equal, also angles 2 and 4 are corresponding angles and they are equal.
so;
5x - 38 = 3x - 4 {collect like terms}
5x - 3x = 38 - 4
2x = 34 {divide through by 2}
x = 17
angle 3 = 5(17) - 38
angle 3 = 85 - 38
angle 3 = 47°
angle 4 = 180° - 47° {angles 3 and 4 are supplementary angles so their sum is equal to 180°}
angle 4 = 133°
Therefore, the measure of the angle 4 is equal to 133° since it is a supplementary angle to angle 3 and it corresponds to the angle 2.
