I suppose you're asking about the inverse Laplace transform of
[tex]F(s)=\dfrac4{(s-3)(s-2)}[/tex]
by way of the convolution theorem.
The theorem itself says that
[tex]\mathscr L^{-1}\{A(s)B(s)\}=(a*b)(t)[/tex]
where [tex]A(s)[/tex] and [tex]B(s)[/tex] are the Laplace transforms of [tex]a(t)[/tex] and [tex]b(t)[/tex], respectively.
Let [tex]A(s)=\frac1{s-3}[/tex] and [tex]B(s)=\frac1{s-2}[/tex]. Then
[tex]a(t)=\mathscr L^{-1}\left\{\dfrac1{s-3}\right\}=e^{3t}[/tex]
[tex]b(t)=\mathscr L^{-1}\left\{\dfrac1{s-2}\right\}=e^{2t}[/tex]
So we have
[tex]\mathscr L^{-1}\left\{\dfrac4{(s-3)(s-2)}\right\}=e^{3t}*e^{2t}[/tex]
Convolution is defined as
[tex](a*b)(t)=\displaystyle\int_0^t a(t-\tau)b(\tau)\,\mathrm d\tau[/tex]
The convolution of [tex]e^{3t}[/tex] and [tex]e^{2t}[/tex] is
[tex]e^{3t}*e^{2t}=\displaystyle\int_0^t e^{3(t-\tau)}e^{2\tau}\,\mathrm d\tau[/tex]
[tex]=\displaystyle e^{3t} \int_0^t e^{-\tau}\,\mathrm d\tau[/tex]
[tex]=e^{3t}(1-e^{-t})=e^{3t}-e^{2t}[/tex]
We end up with
[tex]\mathscr L^{-1}\left\{\dfrac4{(s-3)(s-2)}\right\}=\boxed{4(e^{3t}-e^{2t})}[/tex]

1. Original numbers are rounded to the nearest hundred and to the nearest thousand. The
original numbers are different from all the rounded numbers in the table.
Complete the table with possible original numbers.
Original Number
Rounded to the Nearest
Hundred
13,600
Rounded to the Nearest
Thousand
14,000
2,400
2,000
Answer:
Your answer would be 14,000
Answer:13,555
Step-by-step explanation: because in order for it to be rounded to the nearest 100 of 600 it would have to be over 550. If it was 550 or lower it would be rounded to 500. And in order for it to be rounded to the nearest thousand of 14,000 it would have to be a higher number than 13,550.

)) All figures in Group 2 are triangular
prisms
1) All figures in Group 1 appear to have at
least one square face,
Answer:
All figures in Group 1 appear to have at
least one square face
Step-by-step explanation:
Let us examine each statement and see whether they are true or not.
The first statement is not true. Only one of the figures (square pyramid) has at least one triangular face. It has 4 triangular faces, actually.
The second statement is not true. Only one of the figures is a rectangular prism. The remaining two are triangular pyramid and triangular prism respectively.
The third statement is not true also. Only 1 figure is a triangular prism.
The fourth statement is correct. In group 1, all the figures has at least one square face.
8. Kathy is painting the outside of her
house. Its area is 2,250 square feet. Each
gallon of paint covers 250 square feet
and costs $19.90. How much money is
she going to spend on paint to cover the
outside of her house?
Answer:
$179.1
Step-by-step explanation:
Total area to be painted = 2,250 sq.ft
area covered by per gallon of paint = 250 sq.ft
Hence, gallons of paint required to paint 2,250 sq.ft is...
2250/250 = 9
so, 9 gallons of paint are required to paint 2,250 sq.ft
cost per gallon of paint = $19.90
so, cost of 9 gallons is...
19.90*9 = 179.1
The total money that Kathy will spend for painting the outside of her house is $179.1.
What is Unitary Method?
The unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value.
Given is the Kathy who is painting the outside of her house. Its area is 2,250 square feet. Each gallon of paint covers 250 square feet and costs $19.90.
Area of the outer house = [A] = 2250 ft²
Area covered by 1 gallon of paint = [a] = 250 ft²
Therefore, the total gallons of paint needed = (2250/250) = 9 gallons.
Cost of 9 gallons of paint will be = 19.90 x 9 = 179.1
Therefore, the total money that Kathy will spend for painting the outside of her house is $179.1.

During a science experiment, Daniel noted the starting
temperature of a -4°F. At the end of the experiment, the
change in temperature was -5°F. What was the final
temperature?
A.-1 B.1 C.9 D.-9
Answer: D. - 9
Step-by-step explanation:
Give the following :
Starting temperature = - 4°F
At the end of the experiment, the change in temperature was -5°F
What was the final temperature?
Taking the difference of the starting temperature and the final temperature should give the change in temperature over the course of the experiment.
Δtemperature = (final temperature - initial temperature)
Δtemperature = - 5°F
Initial /starting temperature = - 4°F
Hence,
-5 = final temperature - (-4)
-5 = final temperature + 4
Final temperature = - 5 - 4
Final temperature = - 9

3 = 72/24
Step-by-step explanation:
if this answers it or it is just 12
The least common multiple of these two denominators 6 and 12 is 2.
To find the least common multiple (LCM) of the denominators 6 and 12, follow these steps:
Step 1: Prime factorize each denominator.
6 = 2 × 3
12 = 2 × 2 × 3
Step 2: Identify the highest power of each prime factor.
In this case, the highest power of 2² is 2 and the highest power of 3 is 3.
Step 3: Multiply the highest powers of all prime factors.
[tex]2^2 * 3^1 = 4 * 3 = 12[/tex]
Therefore, the LCM of the denominators 6 and 12 is 2.

HELPPPPPP ASAP . Which triangle represents the reflection ABC across the y-axis ?
Answer:
The answer above me is wrong, it is C, red triangle.
Step-by-step explanation:
Got it right on a school test.
The red triangle represents the reflection ABC across the y-axis. Option C is correct.
What is geometric transformation?It is described as the modification of both the geometric body's coordinates and form. A two-dimensional transformation is another name for it. Geometric transformations allow for the rotation, translation, reflection, and glide translation of the geometry.
We have to find the triangle that represents the reflection ABC across the y-axis.
A flip is a term for a reflection in geometry. The form is mirrored in a reflection. The line of reflection is a line across which an image will reflect. Every point in a figure is said to mirror the other figure if and only if it is equally spaced from every corresponding point in the other figure.
Since the green and blue triangles are equidistant from the y-axis. The red triangle will represent the reflection ABC across the y-axis
Thus, option C is correct.
