The table below shows the distances Maggie and Mikayla can travel walking and riding their bikes for 0, 1, 2, 3, and 4 hours:

Concept of speed

| Time (hours) | Walking Distance (miles) | Biking Distance (miles) |

|--------------|-------------------------|------------------------|

| 0            | 0                       | 0                      |

| 1            | 3.5                     | 10                     |

| 3            | 10.5                    | 30                     |

| 4            | 14                      | 40                     |

The table displays the distances that Maggie and Mikayla can travel by walking and riding their bikes for different durations. Since they can walk at a speed of 3.5 miles per hour and ride their bikes at 10 miles per hour, the distances covered are proportional to the time spent.

For example, when no time has elapsed (0 hours), they haven't traveled any distance yet, so the walking distance and biking distance are both 0. After 1 hour, they would have walked 3.5 miles and biked 10 miles since the speeds are constant over time.

By multiplying the time by the respective speed, we can calculate the distances for each row in the table. For instance, after 2 hours, they would have walked 7 miles (2 hours * 3.5 miles/hour) and biked 20 miles (2 hours * 10 miles/hour).

As the duration increases, the distances covered also increase proportionally. After 3 hours, they would have walked 10.5 miles and biked 30 miles. After 4 hours, they would have walked 14 miles and biked 40 miles.

This table provides a clear representation of how the distances traveled by Maggie and Mikayla vary based on the time spent walking or riding their bikes.

Both differential equation, a. Iny dx + dy = 0 and b. (tany+x) dx + (cos x+8y²)dy = 0, are not exact.

a) A differential equation in the form P(x, y)dx + Q(x, y)dy = 0 is considered an exact differential equation if it can be expressed as dF = (∂F/∂x)dx + (∂F/∂y)dy.

Given the differential equation Iny dx + dy = 0, we can determine if it is exact or not. Here, P(x, y) = Iny and Q(x, y) = 1. Calculating the partial derivatives, we find ∂P/∂y = 1/y and ∂Q/∂x = 0. Since ∂P/∂y is not equal to ∂Q/∂x, the differential equation Iny dx + dy = 0 is not exact.

b) A differential equation in the form P(x, y)dx + Q(x, y)dy = 0 is considered an exact differential equation if it can be expressed as dF = (∂F/∂x)dx + (∂F/∂y)dy.

Given the differential equation (tany+x) dx + (cos x+8y²)dy = 0, we can determine if it is exact or not. Here, P(x, y) = tany+x and Q(x, y) = cos x+8y². Calculating the partial derivatives, we find ∂P/∂y = sec² y and ∂Q/∂x = -sin x. Since ∂P/∂y is not equal to ∂Q/∂x, the differential equation (tany+x) dx + (cos x+8y²)dy = 0 is not exact.

Therefore, we cannot find a potential function F(x, y) such that dF = (tany+x) dx + (cos x+8y²)dy = 0.

C is the positively oriented boundary of the triangle with vertices (0,0), (0, 1) and (-1,0). The line integral [ F. dr = [² da ·√ y² dx + (2xy + x) dy is 13/18.

The given line integral is as follows:[ F. dr = [² da ·√ y² dx + (2xy + x) dy.

Let C be the positively oriented boundary of the triangle with vertices (0,0), (0, 1) and (-1,0).

We have to evaluate the line integral.

Now, first we will consider the boundary of the triangle C. It can be represented as shown below:

Here, AB = √1²+0²=1AC = √1²+1²=√2BC = √1²+1²=√2

Using the concept of Green’s Theorem, we can write the line integral as follows:

[ F. dr =∬( ∂ Q ∂ x − ∂ P ∂ y )d A............................(1)

Here, F = (²√y, 2xy + x) and

P = ²√y, Q = 2xy + x[ ∂ Q ∂ x = 2y + 1∂ P ∂ y = 1 / 2 y^(-1/2)

Hence substituting these values in equation (1), we get:

[ F. dr = ∬( 2y + 1 - 1 / 2 y^(-1/2))d A

From the graph, we can see that the triangle C lies in the first quadrant.

Hence, the limits of integration can be written as below:0 ≤ x ≤ 1 and 0 ≤ y ≤ 1 – x

Now substituting the above limits, we get:

⇒ [ F. dr = ∫₀¹ ∫₀¹⁻x ( 2y + 1 - 1 / 2 y^(-1/2)) dy dx

On integrating with respect to y, we get:

[ F. dr = ∫₀¹ (- 2/3 y^3/2 + y^2 + y ) |₀ (1 – x) dx

Substituting the limits, we get:

[ F. dr = ∫₀¹ (1 – 5/6 x^3/2 + x²) dx

On integrating, we get:

[ F. dr = (x – 5/18 x^5/2 / (5/2)) |₀¹[ F. dr = (1 – 5/18) – (0 – 0) = 13/18

Therefore, [ F. dr = 13/18. Hence, this is the final answer.

The work done in raising the elevator from the basement to the top floor, a distance of 24 feet, is 42,912 foot-pounds.

To calculate the work done, we need to consider the weight of the elevator and the weight of the cables. The weight of the elevator is given as 1500 pounds, and the weight of the cables is given as 12 pounds per foot. Since the total distance traveled by the elevator is 24 feet, the total weight of the cables is 12 pounds/foot × 24 feet = 288 pounds.

The total weight that needs to be lifted is the sum of the elevator weight and the cable weight, which is 1500 pounds + 288 pounds = 1788 pounds.

Work is defined as the force applied to an object multiplied by the distance over which the force is applied. In this case, the force applied is equal to the weight being lifted, and the distance is the height the elevator is raised.

So, the work done in raising the elevator is given by the equation:

Work = Force × Distance

In this case, the force is the weight of the elevator and cables, which is 1788 pounds, and the distance is 24 feet.

Work = 1788 pounds × 24 feet = 42,912 foot-pounds.

Therefore, the work done in raising the elevator from the basement to the top floor is 42,912 foot-pounds.

The simplified expression for (5y² + 7y) - (3y² + 9y - 8) is 2y² - 2y + 8. This is obtained by distributing the negative sign and combining like terms.

To perform the indicated operation of (5y² + 7y) - (3y² + 9y - 8), we need to simplify the expression by combining like terms.

First, let's distribute the negative sign to the terms inside the parentheses:

(5y² + 7y) - (3y² + 9y - 8) = 5y² + 7y - 3y² - 9y + 8

Now, we can combine like terms by adding or subtracting coefficients of the same degree:

(5y² + 7y) - (3y² + 9y - 8) = (5y² - 3y²) + (7y - 9y) + 8

= 2y² - 2y + 8

(a) In the given game, the Nash equilibria in pure strategies are (X, A), (X, C), (Y, B), and (Z, A). In each of these equilibria, no player can improve their payoff by unilaterally changing their action.

In a simultaneous-move game, players choose their actions simultaneously without knowing what actions the other players will take. To find the Nash equilibria in pure strategies, we need to examine all possible combinations of actions and determine if any player has an incentive to deviate.

In this particular game, we have three actions for Player 1 (X, Y, Z) and three actions for Player 2 (A, B, C). By comparing the payoffs for each combination of actions, we can identify the Nash equilibria.

After evaluating all possible combinations, we find that there are four Nash equilibria in pure strategies: (X, A), (X, C), (Y, B), and (Z, A). These equilibria indicate that, at these action combinations, no player has an incentive to unilaterally switch to a different action, as it would result in a lower payoff for them.

The general solution of the given differential equation Dx = 2t, with D² = (1 1)², is A(1) - Ge²¹(1) + 0₂(1) = C2.

To find the general solution of the differential equation Dx = 2t, we start by integrating both sides of the equation with respect to x. This gives us the antiderivative of Dx on the left-hand side and the antiderivative of 2t on the right-hand side. Integrating 2t with respect to x yields t² + C₁, where C₁ is the constant of integration.

Next, we apply the operator D² = (1 1)² to the general solution we obtained. This operator squares the derivative and produces a new expression. In this case, (1 1)² simplifies to (2 2).

Now we have D²(t² + C₁) = (2 2)(t² + C₁). Expanding this expression gives us D²(t²) + D²(C₁) = 2t² + 2C₁.

Since D²(t²) = 0 (the second derivative of t² is zero), we can simplify the equation to D²(C₁) = 2t² + 2C₁.

At this point, we introduce the solution A(1) - Ge²¹(1) + 0₂(1) = C₂, where A, G, and C₂ are constants. This is the general solution to the differential equation Dx = 2t, with D² = (1 1)².

The solution to the given system of differential equations is:

x(t) = c₁cos(2t) + c₂sin(2t)

y(t) = c₃cos(√3t) + c₄sin(√3t)

To solve the given system of differential equations:

(D² + 4)x - 3y = 0   ...(1)

-2x + (D² + 3)y = 0   ...(2)

Let's start by finding the characteristic equation for each equation:

For equation (1), the characteristic equation is:

r² + 4 = 0

Solving this quadratic equation, we find two complex conjugate roots:

r₁ = 2i

r₂ = -2i

Therefore, the homogeneous solution for equation (1) is:

x_h(t) = c₁cos(2t) + c₂sin(2t)

For equation (2), the characteristic equation is:

r² + 3 = 0

Solving this quadratic equation, we find two complex conjugate roots:

r₃ = √3i

r₄ = -√3i

Therefore, the homogeneous solution for equation (2) is:

y_h(t) = c₃cos(√3t) + c₄sin(√3t)

Now, we need to find a particular solution. Since the right-hand side of both equations is zero, we can choose a particular solution that is also zero:

x_p(t) = 0

y_p(t) = 0

The general solution for the system is then the sum of the homogeneous and particular solutions:

x(t) = x_h(t) + x_p(t) = c₁cos(2t) + c₂sin(2t)

y(t) = y_h(t) + y_p(t) = c₃cos(√3t) + c₄sin(√3t)

Therefore, the solution to the given system of differential equations is:

x(t) = c₁cos(2t) + c₂sin(2t)

y(t) = c₃cos(√3t) + c₄sin(√3t)

The minimum monthly payment to pay off a $5500 loan with a 5% interest rate for a term of 2 years is $247.49.

To calculate the minimum monthly payment to pay off a $5500 loan with a 5% interest rate for a term of 2 years, you can use the formula for calculating the monthly payment on a loan, which is:

P = (L[i(1 + i)ⁿ])/([(1 + i)ⁿ] - 1) where:

P = monthly payment

L = loan amount

i = interest rate per month

n = number of months in the loan term

Given:

L = $5500

i = 0.05/12 (5% annual interest rate divided by 12 months)

= 0.0041667

n = 2 years x 12 months/year

The solution to the given equation [xcos^2(y/x)−y]dx+xdy=0, when x=1 and y=π/4, is:

e^0 * (1/2)^2 + h(π/4) = 1/4 + h(π/4) = C1

1 + g(1) = C1

The given equation is [xcos^2(y/x)−y]dx+xdy=0.
To solve this equation, we can use the method of exact differential equations. For an equation to be exact, it must satisfy the condition:
∂M/∂y = ∂N/∂x
where M is the coefficient of dx and N is the coefficient of dy.
In this case, M = xcos^2(y/x) - y and N = x. Let's calculate the partial derivatives:
∂M/∂y = -2xsin(y/x)cos(y/x) - 1
∂N/∂x = 1
Since ∂M/∂y is not equal to ∂N/∂x, the equation is not exact. However, we can make it exact by multiplying the entire equation by an integrating factor.
To find the integrating factor, we divide the difference between the partial derivatives of M and N with respect to x and y respectively:
(∂M/∂y - ∂N/∂x)/N = (-2xsin(y/x)cos(y/x) - 1)/x = -2sin(y/x)cos(y/x) - 1/x
Now, let's integrate this expression with respect to x:
∫(-2sin(y/x)cos(y/x) - 1/x) dx = -2∫sin(y/x)cos(y/x) dx - ∫(1/x) dx
The first integral on the right-hand side requires substitution. Let u = y/x:
∫sin(u)cos(u) dx = ∫(1/2)sin(2u) du = -(1/4)cos(2u) + C1

The second integral is a logarithmic integral:
∫(1/x) dx = ln|x| + C2
Therefore, the integrating factor is given by:
μ(x) = e^∫(-2sin(y/x)cos(y/x) - 1/x) dx = e^(-(1/4)cos(2u) + ln|x|) = e^(-(1/4)cos(2y/x) + ln|x|)
Multiplying the given equation by the integrating factor μ(x), we get:
e^(-(1/4)cos(2y/x) + ln|x|)[xcos^2(y/x)−y]dx + e^(-(1/4)cos(2y/x) + ln|x|)xdy = 0

Now, we need to check if the equation is exact. Let's calculate the partial derivatives of the new equation with respect to x and y:
∂/∂x[e^(-(1/4)cos(2y/x) + ln|x|)[xcos^2(y/x)−y]] = 0
∂/∂y[e^(-(1/4)cos(2y/x) + ln|x|)[xdy]] = 0
Since the partial derivatives are zero, the equation is exact.

To find the solution, we need to integrate the expression ∂/∂x[e^(-(1/4)cos(2y/x) + ln|x|)[xcos^2(y/x)−y]] with respect to x and set it equal to a constant. Similarly, we integrate the expression ∂/∂y[e^(-(1/4)cos(2y/x) + ln|x|)[xdy]] with respect to y and set it equal to the same constant.

Integrating the first expression ∂/∂x[e^(-(1/4)cos(2y/x) + ln|x|)[xcos^2(y/x)−y]] with respect to x:
e^(-(1/4)cos(2y/x) + ln|x|)cos^2(y/x) + h(y) = C1
where h(y) is the constant of integration.
Integrating the second expression ∂/∂y[e^(-(1/4)cos(2y/x) + ln|x|)[xdy]] with respect to y:
e^(-(1/4)cos(2y/x) + ln|x|)x + g(x) = C1
where g(x) is the constant of integration.

Now, we have two equations:
e^(-(1/4)cos(2y/x) + ln|x|)cos^2(y/x) + h(y) = C1
e^(-(1/4)cos(2y/x) + ln|x|)x + g(x) = C1

Since x = 1 and y = π/4, we can substitute these values into the equations:
e^(-(1/4)cos(2(π/4)/1) + ln|1|)cos^2(π/4/1) + h(π/4) = C1
e^(-(1/4)cos(2(π/4)/1) + ln|1|) + g(1) = C1

Simplifying further:
e^(-(1/4)cos(π/2) + 0)cos^2(π/4) + h(π/4) = C1
e^(-(1/4)cos(π/2) + 0) + g(1) = C1

Since cos(π/2) = 0 and ln(1) = 0, we have:
e^0 * (1/2)^2 + h(π/4) = C1
e^0 + g(1) = C1

Simplifying further:
1/4 + h(π/4) = C1
1 + g(1) = C1

Therefore, the solution to the given equation [xcos^2(y/x)−y]dx+xdy=0, when x=1 and y=π/4, is:

e^0 * (1/2)^2 + h(π/4) = 1/4 + h(π/4) = C1
1 + g(1) = C1

First, let's calculate the monthly interest rate. The nominal interest rate is given as 1.8%, which means the monthly interest rate is 1.8% divided by 12 (number of months in a year):

r = 1.8% / 12 = 0.015

Next, let's calculate the total number of payments. The mortgage has a 30-year amortization period, which means there will be 30 years * 12 months = 360 monthly payments.

n = 360

Now, let's calculate Mike's monthly payments using the formula:

P = (0.015 * (1.3m - 300k)) / (1 - (1 + 0.015)^(-360))

Substituting the values:

P = (0.015 * (1,300,000 - 300,000)) / (1 - (1 + 0.015)^(-360))

Simplifying the expression:

P = (0.015 * 1,000,000) / (1 - (1 + 0.015)^(-360))

P = 15,000 / (1 - (1 + 0.015)^(-360))

Calculating further:

P = 15,000 / (1 - (1.015)^(-360))

P ≈ 15,000 / (1 - 0.22744)

P ≈ 15,000 / 0.77256

P ≈ 19,407.43

Therefore, Mike's monthly payments are approximately $19,407.43.

To calculate the balance at time 60, we can use the formula for calculating the remaining loan balance after t payments:

Bt = P * ((1 - (1 + r)^(-(n-t)))) / r

Where:
Bt = Balance at time t
P = Monthly payment
r = Monthly interest rate
n = Total number of payments
t = Number of payments made

Substituting the values:

B60 = 19,407.43 * ((1 - (1 + 0.015)^(-(360-60)))) / 0.015

B60 = 19,407.43 * ((1 - (1.015)^(-300))) / 0.015

B60 ≈ 19,407.43 * ((1 - 0.19025)) / 0.015

B60 ≈ 19,407.43 * 0.80975 / 0.015

B60 ≈ 19,407.43 * 53.9833

B60 ≈ 1,048,446.96

Therefore, at the end of the 5-year term (time 60), Mike owes approximately $1,048,446.96.

IF the tax rate is 17% then capital gain tax will the seller pay is $0 , The correct answer would be Option F, $0.

The capital gains tax that the seller would pay is as follows:

In order to determine the capital gain, subtract the cost basis from the sales price: $66,000 − $11,000 = $55,000.

Since the equipment is being sold at a loss ($55,000 < $110,000), it cannot be depreciated. Therefore, the entire $55,000 would be treated as a capital loss for tax purposes.

If the tax rate is 17%, then the capital gain tax will be 17% of $0, which is $0.

Therefore, the answer is none of the choices. The correct answer would be Option F, $0.

To show that a set V, together with an addition operation and a scalar multiplication operation, forms a vector space, we need to verify that it satisfies the following properties:

Closure under addition: For any vectors u and v in V, their sum u + v is also in V.

Associativity of addition: For any vectors u, v, and w in V, (u + v) + w = u + (v + w).

Commutativity of addition: For any vectors u and v in V, u + v = v + u.

Identity element of addition: There exists an element 0 in V such that for any vector u in V, u + 0 = u.

Inverse element of addition: For every vector u in V, there exists a vector -u in V such that u + (-u) = 0.

Closure under scalar multiplication: For any scalar c and vector u in V, their scalar product c * u is also in V.

Associativity of scalar multiplication: For any scalars c and d and vector u in V, (cd) * u = c * (d * u).

Distributivity of scalar multiplication over vector addition: For any scalar c and vectors u and v in V, c * (u + v) = c * u + c * v.

Distributivity of scalar multiplication over scalar addition: For any scalars c and d and vector u in V, (c + d) * u = c * u + d * u.

Identity element of scalar multiplication: For any vector u in V, 1 * u = u, where 1 denotes the multiplicative identity of the scalar field.

If all these properties are satisfied, then the set V, together with the specified addition and scalar multiplication operations, is a vector space.

On the other hand, to show that a set V, together with an addition operation and a scalar multiplication operation, does NOT form a vector space, we only need to find a counter example where at least one of the properties mentioned above is violated.

Regarding the set of all integers together with standard addition and scalar multiplication, it does not form a vector space. The main reason is that it does not satisfy closure under scalar multiplication.

For example, if we take the scalar c = 1/2 and the integer u = 1, the product (1/2) * 1 = 1/2 is not an integer. Therefore, the set of all integers with standard addition and scalar multiplication does not fulfill the requirement of closure under scalar multiplication and, hence, is not a vector space.

Step-by-step explanation:

The extreme points (x, y) along the curve of the function f(x, y) = e²x² + xy + y² = 1 are (-1, 0) and (1, 0).

To find the extreme points of the function f(x, y) = e²x² + xy + y² = 1, we can use calculus. First, we need to calculate the partial derivatives of the function with respect to x and y. Taking the partial derivative with respect to x, we get:

∂f/∂x = 2e²x² + y

And taking the partial derivative with respect to y, we get:

∂f/∂y = x + 2y

To find the extreme points, we need to set both partial derivatives equal to zero and solve the resulting system of equations. From ∂f/∂x = 0, we have:

2e²x² + y = 0

From ∂f/∂y = 0, we have:

x + 2y = 0

Solving these equations simultaneously,

Equation 1: 2e²x² + y = 0

Equation 2: x + 2y = 0

We can use substitution or elimination method.

Using the elimination method:

Multiply Equation 2 by 2 to make the coefficients of y equal in both equations:

2(x + 2y) = 2(0)

2x + 4y = 0

Now we have the following system of equations:

2e²x² + y = 0

2x + 4y = 0

We can solve this system of equations by substituting Equation 2 into Equation 1:

2e²x² + (-2x) = 0

2e²x² - 2x = 0

Factoring out 2x:

2x(e²x - 1) = 0

Setting each factor equal to zero:

2x = 0 --> x = 0

e²x - 1 = 0

e²x = 1

Taking the square root of both sides:

e^x = ±1

Taking the natural logarithm of both sides:

x = ln(±1)

The natural logarithm of a negative number is undefined, so we consider only the case when x = ln(1):

x = 0

Now substitute the value of x = 0 into Equation 2 to find y:

0 + 2y = 0

2y = 0

y = 0

Therefore, the solution to the system of equations is (x, y) = (0, 0).

We find that x = -1 and y = 0, or x = 1 and y = 0. These are the two extreme points along the curve.

To find the general solution of the given differential equation, let's follow the procedures developed in this chapter. The differential equation is y′′−2y′+y=x^2e^x.

Step 1: Solve the homogeneous equation
To start, let's find the solution to the homogeneous equation y′′−2y′+y=0. The characteristic equation is r^2-2r+1=0, which can be factored as (r-1)^2=0. This gives us a repeated root of r=1.

The general solution to the homogeneous equation is y_h=c_1e^x+c_2xe^x, where c_1 and c_2 are constants.

Step 2: Find a particular solution
To find a particular solution to the non-homogeneous equation y′′−2y′+y=x^2e^x, we can use the method of undetermined coefficients. Since the right side of the equation is a polynomial multiplied by an exponential function, we assume a particular solution of the form y_p=(Ax^2+Bx+C)e^x, where A, B, and C are constants to be determined.

Differentiating y_p twice, we have y_p′′=(2A+2Ax+B)e^x and y_p′=(2A+2Ax+B)e^x+(Ax^2+Bx+C)e^x.

Substituting these derivatives into the original differential equation, we get:
(2A+2Ax+B)e^x-2[(2A+2Ax+B)e^x+(Ax^2+Bx+C)e^x]+(Ax^2+Bx+C)e^x=x^2e^x.

Simplifying the equation, we have 2Ax^2e^x+(2B-4A+2A)x+(B-2B+C+2A)=x^2e^x.

By comparing coefficients, we can determine the values of A, B, and C:
2A=1 (from the coefficient of x^2e^x)
2B-4A+2A=0 (from the coefficient of xe^x)
B-2B+C+2A=0 (from the constant term)

Solving these equations, we find A=1/2, B=1, and C=-2.

Therefore, a particular solution to the non-homogeneous equation is y_p=(1/2)x^2e^x+x^e^x-2e^x.

Step 3: Write the general solution
The general solution to the non-homogeneous equation is the sum of the homogeneous solution and the particular solution:
y=y_h+y_p=c_1e^x+c_2xe^x+(1/2)x^2e^x+x^e^x-2e^x.

So, the general solution of the given differential equation is y=c_1e^x+c_2xe^x+(1/2)x^2e^x+x^e^x-2e^x.

Here are four crucial steps in the process of helping learners to build the relational skill that can help them to make sense of the numbers in an arithmetic pattern:

Look for the constant difference: In an arithmetic pattern, a constant number is added or subtracted each time to form consecutive terms. Encourage learners to identify this constant difference by subtracting any two adjacent numbers in the sequence. In this case, subtracting 4 from 7 gives 3, and subtracting 7 from 10 also gives 3. Therefore, the constant difference is 3.

Use the constant difference to predict future terms: Once the constant difference is identified, learners can use it to predict future terms in the sequence. For example, adding 3 to the last term (13) gives 16. This means that the next term in the sequence will be 16.

Check the prediction: Predicting the next term is not enough. Learners should also check their prediction by verifying it against the actual pattern. In this case, the next term in the sequence is indeed 16.

Generalize the pattern: Finally, encourage learners to generalize the pattern by expressing it in a formulaic way. In this case, the formula would be: nth term = 3n + 1. Here, n represents the position of the term in the sequence. For example, the fourth term (position n=4) would be 3(4) + 1 = 13.

By following these four crucial steps, learners can build their relational skills and be more efficient in making sense of arithmetic patterns like the one given.

The value of time t = 1 in the given expression is approximately 12.6964.

To calculate the inverse Laplace transform of the expression 1/[(s – 2)(s – 3)], we can use the partial fraction decomposition method.

First, we need to factorize the denominator:

[tex](s – 2)(s – 3) = s^2 – 5s + 6[/tex]

The partial fraction decomposition is given by:

1/[(s – 2)(s – 3)] = A/(s – 2) + B/(s – 3)

To find the values of A and B, we can multiply both sides by (s – 2)(s – 3):

1 = A(s – 3) + B(s – 2)

Expanding and equating coefficients, we get:

1 = (A + B)s + (-3A – 2B)

From the above equation, we obtain two equations:

A + B = 0 (coefficient of s)

-3A – 2B = 1 (constant term)

Solving these equations, we find A = -1 and B = 1.

Now, we can rewrite the expression as:

1/[(s – 2)(s – 3)] = -1/(s – 2) + 1/(s – 3)

The inverse Laplace transform of[tex]-1/(s – 2) is -e^(2t)[/tex] , and the inverse Laplace transform of 1/(s – 3) is [tex]e^(3t).[/tex]

Substituting t = 1 into the expression, we have:

t = 1, the value of the expression [tex]-e^{(2t)} + e^{(3t)}[/tex] is approximately 12.6964.

To calculate the inverse Laplace transform of the expression 1/[(s - 2)(s - 3)], we can use partial fraction decomposition.

Let's rewrite the expression as:

1 / [(s - 2)(s - 3)] = A/(s - 2) + B/(s - 3)

To find the values of A and B, we can multiply both sides of the equation by (s - 2)(s - 3):

1 = A(s - 3) + B(s - 2)

Expanding and equating coefficients:

1 = (A + B)s + (-3A - 2B)

From this equation, we can equate the coefficients of s and the constant term separately:

Coefficient of s: A + B = 0 ... (1)

Constant term: -3A - 2B = 1 ... (2)

Solving equations (1) and (2), we find A = -1 and B = 1.

Now, we can rewrite the expression as:

1 / [(s - 2)(s - 3)] = -1/(s - 2) + 1/(s - 3)

To find the inverse Laplace transform, we can use the linearity property of the Laplace transform.
