write the form of the partial fraction decomposition of the rational expression.Do not solve for the constants.
x-2
________
x^2+11x+28
Answer:
A/(x+7) +B/(x+4)
Step-by-step explanation:
The denominators of the partial fraction expansion are the factors of the denominator of the rational function.
__
Here, the rational function's denominator can be factored as ...
x² +11x +28 = (x +7)(x +4)
Then the form of the decomposition is ...
[tex]\dfrac{x-2}{x^2+11x+28}=\boxed{\dfrac{A}{x+7}+\dfrac{B}{x+4}}[/tex]
_____
Additional comment
Here, A=3. B=-2.
If the factors of the denominator have multiplicity greater than 1, then there is a fraction with each power of that factor up to the multiplicity. For example, if there is a factor (x+4)³, then the decomposition would include fractions A/(x+4) +B/(x+4)² +C/(x+4)³.
what is the weight of a 55 kg person on earth where the acceleration due to gravity is 9.8m/s²
Answer:
The weight of an object is the force of gravity exerted on that object. The mass of an object is the amount of matter it has, and it stays the same wherever you are, regardless of gravity.[1] That's why an object that has 20 kilograms of mass on earth also has 20 kilograms of mass while on the moon, even though it would only weigh 1/6 as much. It weighs 1/6 as much on the moon because the force of gravity on the moon is 1/6 of what it is on Earth.
Step-by-step explanation:
Answer:
your mother
Step-by-step explanation:
The logical answer would be your mother because 9.8m/s^2 x 55 would equal your mother weight, 539 squared pounds.

Answer:
The correct answer is Choice C.
Step-by-step explanation:
I drew a diagram of all the triangles to compare the statements given to each other
I marked the triangle sides with lines to show congruency in length.
One line for AB = DF
Two lines for AB = GI
Three lines for BC = HI
Four lines for DE = HI
The angles are all marked for the last sentence we are given.
The first and third triangles are the only ones similar. This is because of SAS congruence as given in the Diagram. AB = GI, angle B = angle I, BC = IH
The second triangle is different from the rest, and even if we tried to rotate it ad compare it, it would still be wrong.

Find the surface area.
9 in

In this question we are provided with the length breadth and height and we are asked to find the surface area of the figure.
[tex] \small\bf{ Length = 16 \: inches } \\ \small\bf{Breadth = 7 \: inches} \\ \small\bf{Height = \: 9 \: inches} [/tex]
We know,
[tex] \pink\star \: \large\boxed{ \pink{ \rm{ Surface \: area = 2(lb + bh + hl)}}}[/tex]
Substituting the values we get
Surface area = 2(16 × 7 + 7 × 9 + 9 × 16)
= 2(112 + 63 + 144)
= 2(319)
= 638
Surface area = 638 inches².

What is a Triangle around a Point?A triangle around a point is a triangle that is constructed such that a point is equidistant from all the angles and all the sides that triangle. This point is thus referred to as the circumcenter of the triangle.
The triangle in the attached image is drawn around point D.
What is a Line Segment?A Line segment is the part of a line with two endpoints. The box in the diagram is drawn between points A and B.
What does it mean to circle an angle?When you put a circle around an angle, you have circled that angle. This most case is used to highlight an angle.

Which decimal is greater: 0.347 or 0.437?
Answer:
0.437
Step-by-step explanation:
Decimals are read the same as whole numbers, starting with the first digit, which is the largest, to the right. So, to find the larger decimal you need to look at the first digit. If this digit is the same then continue to the right until there is a difference in the number. In this case, the first digit is different. Therefore, whichever has the larger first digit must be the greater one. Since 4 > 3, 0.437 must be greater than 0.347.

The mode is 78
Step-by-step explanation:Mode: The digit that has been repeated the most in a specific data.
To determine the mode of the data, let's arrange the data in ascending order.
Arranging the data in ascending form, we get:
⇒ 74, 77, 78, 78, 80, 81, 82, 91, 92In the ascending data, we can see that: (Refer to underlined and bolded text)
74 has been repeated once77 has been repeated once78 has been repeated twice80 has been repeated once81, has been repeated once82 has been repeated once91 has been repeated once92 has been repeated onceSince 78 has been repeated the most, 78 is the mode of the data.

Amelia needs to buy some dog food. At the nearest store ,5 bags of dog food cost 12.50 how much would Amelia spend on three bags
Answer:
$7.50
Step-by-step explanation:
the question can be represented with:
12.5/5 and x/3
12.5/5 is 2.5, so that means each bag of dog food is $2.5
So then you multiply 2.5 by 3, = 1.20, so 3 bags of dog food is $7.50.
Answer:
Step-by-step explanation:
Remark
I take it you mean 5 and not 0.5.
If that is the case, this is a proportion question. A proportion consists of 4 parts. If you know 3 of the parts, you can solve for the 4th one.
Formula
Number of bags/Cost = new number of bags/Cost of the new number
Givens
original Number of bags = 5
Cost = 12.50
New number of bags = 3 bags
Cost = x
Solution
5/12.50 = 3/x Cross Multiply
5x = 12.50 * 3 Combine the right
5x = 37.5 Divide by 5
5x/5 = 37.5/5
x = 7.5
Answer: 3 bags cost 7.50 dollars.

Answer:
i think c
Step-by-step explanation:
i hope this helped
Answer:
c
Step-by-step explanation:
A, B and C can do a piece of work in 20, 30 and 60 days respectively. In how many days can A do the work if he is assisted by B and C on every third day?
A, B and C working together will finish same piece of work in 10 days
A can do a piece of work in 20 days. That is A is doing the work at a rate of 1 / 20. Therefore
B = 1 / 30
C = 1 / 60
A, B and C working togehter their rate will be added together =
A + B + C = 1 / 20 + 1 / 30 + 1 / 60 = 1 / 10
so they can work together to finish same piece of work in 10 days
help pleaseeeeeeee this is harddddddddddddddddd
Answer:
Step-by-step explanation:
Question #1:
Area of a triangle = bh/2
A = (3)(6)/2 = 18/2 = 9 in²
Total A = 10 x area of a triangle
Total A = 10 x 9 = 90 in²
Question #2:
A = bh/2
Top 2 triangles: (20)(10)/2 x 2 = 200
Bottom 2 triangles: (20)(50)/2 x 2 = 1000
Total A = 1,200 in²
Question #3:
Total area = 2 triangles + 1 square
Triangle A: must find base
a² + b² = c²4² + b² = 6²b = √(36 - 16) = √20 = 2√5Triangle A = bh/2 = (2√5)(4) = 8√5
Square A = bh = (4)(?)
The last one is very hard, can't find the square's base. I hope the rest of my answers help though! Have a nice day!

A) 114 cm2
B) 350 cm2
C) 418 cm2
D) 447 cm2
Answer:
