In the given case- An inverse of a Laplace transform, which is the sum of two distinct components, is the sum of the inverse transforms of each term separately.
What does inverse Laplace transform refer to?
A Laplace transform that is the sum of two different terms has an inverse that is the sum of the inverse transforms of each term taken separately. A Laplace transform, which also has an inverse of the constant multiplied by the inverse of the function, is produced when a constant is multiplied by a function.
A given derivative function with a real variable (t) is transformed into a complex function with a variable (s) by the Laplace transform, which is an integral transformation. Assuming that f(t) complies with a number of later-explained conditions,

Two people are working on a joint project. Each person i puts in some effort x i ∈[0,1], which costs x i 2, and the outcome of the project is worth 2x1x2 . The worth of the project is split equally between them, regardless of their effort. a. Find the Nash equilibria of the game. b. Determine whether there are effort levels that yield a total payoff higher than that of the Nash equilibrium (Hint: factor the total payoff function).
a) The Nash Equilibrium is when both players put in the same effort level x1 = x2 = x.
b) The total payoff is a convex function of x1, which means that increasing x1 will always increase the total payoff.
Nash Equilibrium & Total Payoffa. Nash Equilibrium: A Nash Equilibrium is a set of strategies such that each player's strategy is a best response to the strategies of the other players.
In this game, each person i chooses their effort level x i to maximize their own payoff, which is the worth of the project divided by 2. Their individual payoff is given by:
pi = (2x1x2) / 2 = x1x2
By taking the derivative of pi with respect to xi and setting it to zero, we get the following first-order condition:
dpi/dx i = x2 - xi = 0
Since xi is in the range [0,1], we have xi = x2.
Thus, the Nash Equilibrium is when both players put in the same effort level x1 = x2 = x.
b. Total Payoff: The total payoff of the project is given by:
pt = x1x2 + x1x2 = 2x1x2
By factoring the total payoff function, we get:
pt = 2x1x2 = 2x1x1 = 2x12
So, the total payoff is a convex function of x1, which means that increasing x1 will always increase the total payoff.
Since the Nash Equilibrium is when both players put in the same effort level, there is no effort level that yields a higher total payoff than the Nash Equilibrium.

Income normally uses a ratio scale of measurement.
Hence, option (a) is correct choice.
A ratio scale is a numerical scale with a genuine zero and equal gaps between adjacent points. A zero on a ratio scale, unlike an interval scale, indicates the complete absence of the variable being measured. Ratio scales include length, area, and population.
A ratio scale may be used to label variables, arrange them in order, and calculate the equal distance between variables. The ratio Scale enables unit conversion. British thermal units, such as Joules, kilograms, and grams, are ratio scale units.
As several elements of a given unit, interval scale may quantify size and magnitude. A ratio scale can be used to quantify size and magnitude by dividing one designated unit by another.

The First and third term of geometric progression
are 5 and 80 respectively. What is the 4th term
of geometric progress.
Answer:
±320
Step-by-step explanation:
You want the 4th term of the geometric progression that has first and third terms 5 and 80.
Common ratioThe general term of a geometric sequence is ...
an = a1·r^(n-1)
for first term a1 and common ratio r.
We are given the 1st and 3rd terms, so we can find the common ratio from ...
80 = 5·r^(3-1) . . . . . use a3 = 80, a1 = 5, n = 3
16 = r^2 . . . . . . divide by 5
±4 = r . . . . . . . . take the square root
Fourth termThe 4th term will be the product of the 3rd term and the common ratio:
a4 = a3·(±4) = 80·(±4) = ±320
The fourth term is -320 or +320.
Derrick would like to explore his area. He estimates that his walking speed is 3.5 mph in the difficult terrain he has been given. If Derrick leaves at around 12 pm, and the sun sets at 4:45 pm, how far can he explore and still make it back by sunset?
Answer:
16.625 miles
Step-by-step explanation:
The time elapsed between 4:45 pm and 12 noon is 4 hours and 45 minutes
45 minutes is equivalent to 45/60 = 0.75 hour
Total elapsed time = 4.75 hours
At a speed of 3.5 mph the distance that can be covered
= 3.5 x 4.75 = 16.625 miles
For every 50p Max saves, his mum gives him 20p. Max saves £5.50. How much does he have altogether, including the money his mum gives him?⭐⭐⭐⭐⭐
Max saves £5.50, which is 550p.

7 Jon is using square ceramic tiles, each 20cm x 20cm, to cover a rectangular worktop in his greenhouse. He can fit exactly 6 tiles along the shorter edge of the worktop and 15 along the length. (a) How many tiles will he use, altogether, to cover the orktop? (b) What is the length of the worktop? Give your answer in metres (m). ............m
Answer:
(a) The number of tiles Jon will use to cover the worktop is 6 * 15 = 90 tiles.
(b) To find the length of the worktop, we first need to find the length of each tile, which is 20 cm = 0.2 m.
The length of the worktop is then 0.2 m * 6 tiles = 1.2 m.
The width of the worktop is 0.2 m * 15 tiles = 3 m.
So, the length of the worktop is 1.2 m and the width is 3 m.

Cost and revenue functions. Please tysm!!!
The profit function is P ( x ) = 2x² + 5x - 12 and the number of months during which the company is not making a profit is x = 1.5 years = 18 months
What is an Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the profit function be represented as P ( x )
Let the cost function of the company be C ( x ) = 17 - 8x - 2x²
Let the revenue function of the company be R ( x ) = 5 - 3x
Now , Profit = Revenue - Costs
Substituting the values in the equation , we get
P ( x ) = R ( x ) = C ( x )
P ( x ) = 5 - 3x - ( 17 - 8x - 2x² )
On simplifying the equation , we get
P ( x ) = 2x² + 5x - 12
Now , when the profit of the company is 0
2x² + 5x - 12 = 0
On factorizing the equation , we get
2x² + 8x - 3x - 12 = 0
2x ( x + 4 ) - 3 ( x + 4 ) = 0
Taking the common factors of the equation , we get
( 2x - 3 ) ( x + 4 ) = 0
The value of x cannot be negative , so
2x - 3 = 0
Adding 3 on both sides of the equation , we get
2x = 3
Divide by 2 on both sides of the equation , we get
x = 3/2 years
Therefore , the number of months x = 18 months
Hence , the equation is solved

12. Town A has 4.563 residents.
Town A has 127 more than
4 times the number of residents
of Town B. How many residents
does Town B have?
Answer: We can set up an equation to represent the given information:
4.563 = 4B + 127
where B is the number of residents in Town B.
To solve for B, we can first subtract 127 from both sides:
4.563 - 127 = 4B
Then divide both sides by 4:
B = (4.563 - 127) / 4
B = 1.140775
So Town B has approximately 1.140775 residents.

What do you mean by probability?Probability is a branch of mathematics that deals with the likelihood or chance of an event happening. It is a number between 0 and 1 that indicates the likelihood of an event occurring, with 0 meaning that an event is impossible and 1 meaning that an event is certain to occur.
Probability is used to model and make predictions about real-world situations such as the outcome of a coin flip, the results of a survey, or the success of a marketing campaign. It is also used in many fields including statistics, finance, engineering, and sciences to make decisions based on uncertain data.
Probabilities can be calculated using various methods, such as counting, Bayes' theorem, and simulation. In general, the probability of an event is calculated by dividing the number of favorable outcomes by the total number of possible outcomes.

Write down the percentage multiplier to find 26% of an amount
pls do simple steps/working out :)
Answer:
To find 26% of an amount, you would use the percentage multiplier of 0.26.
Step-by-step explanation:
To use the multiplier, you would simply multiply the amount by 0.26.
For example:
26% of $100 = $100 x 0.26 = $26.
Alternatively, you can also express the percentage as a decimal by moving the decimal point two places to the left. In this case 26% is equal to 0.26
So, to find 26% of an amount you would multiply the amount by 0.26
For example:
26% of $100 = $100 x 0.26 = $26.
