What is the partial fraction decomposition of
8x+19/(x+8)(x-1)?
Answer:
8x+19/(x+8)(x-1)= 5/(x+8) + 3/(x-1)
Step-by-step explanation:
Step one:
given the expression
8x+19/(x+8)(x-1)
in partial fraction the expression is
8x+19/(x+8)(x-1)= A/(x+8) + B/(x-1)
8x+19/(x+8)(x-1)= A(x-1)+B(x+8)/(x+8)(x-1)
equating the numerator we have
8x+19=A(x-1)+B(x+8)-------------------------1
to find A put x=-8 in eqn 1
8(-8)+19=A(-8-1)+B(-8+8)
-64+19=-9A
-45=-9A
A=45/9
A=5
to find B put x=1 in eqn 1
8(1)+19=A(1-1)+B(1+8)
8+19=9B
27=9B
B=27/9
B=3
The partial fraction decomposition
8x+19/(x+8)(x-1)= 5/(x+8) + 3/(x-1)

Option-B

Mr. Tucker earns $250 per week working in an appliance store. In addition, he earns 2% commission on all of his sales. Last week, he sold $2,800 worth of appliances. What was Mr. Tucker’s total income for the week?
Answer:
306 dollars is his total income
Step-by-step explanation:
You just have to multiply 2,800 dollars by 0.02 because the commission is 2%. when You multiply both the product is 56. Add 56 to his weekly income of250 and dolars and you get. 306 dollars for this weks total income.

The perimeter of the rectangle below is 134 units. Find the length of side RS. Write your answer without variables
Answer:
RS = 30 units
Step-by-step explanation:
Given:
Length (PS) = [tex] 4y + 1 [/tex]
Width (PQ) = [tex] 3y + 3 [/tex]
Perimeter = 134 units
Required:
RS (width)
SOLUTION:
Perimeter of a rectangle = 2(length + width)
Plug in the values into the equation
134 = 2[(4y + 1) + (3y + 3)]
134 = 2[4y + 1 + 3y + 3]
134 = 2[7y + 4]
134 = 14y + 8
Subtract 8 from each side of the equation
134 - 8 = 14y
126 = 14y
Divide both sides by 14.
126/14 = 14y/14
9 = y
y = 9
✍️RS = Width (PQ) = [tex] 3y + 3 [/tex]
Plug in the value of y
RS = tex] 3(9) + 3 [/tex]
RS = tex] 27 + 3 [/tex]
RS = 30

Consider functions f and g.
What is the value of ?
The words don't actually matter, it is the picture that has the question.
Answer:
we get [tex]\mathbf{(g \ o \ f)(4)=9}[/tex]
Option C is correct.
Step-by-step explanation:
We are given:
[tex]f(x)=-x^3\\g(x)= |\frac{1}{8}x-1|[/tex]
We need to find (g о f)(4)
For finding (g о f)(4) we will first find g(f(x)) i.e putting value of f(x) inside g(x) and then put x=4
[tex](g \ o \ f)(x)=g(f(x))\\(g \ o \ f)(x)=|\frac{1}{8}(-x^3)-1 |[/tex]
Now, putting x=4
[tex](g \ o \ f)(x)=|\frac{1}{8}(-x^3)-1 |\\Put \ x=4\\(g \ o \ f)(4)=|\frac{1}{8}(-(4)^3)-1 |\\(g \ o \ f)(4)=|\frac{1}{8}(-64)-1 |\\(g \ o \ f)(4)=|-8-1 |\\(g \ o \ f)(4)=|-9| \\\\We \ will \ use \ absolute \ value \ i.e \ 9 \\(g \ o \ f)(4)=9[/tex]
So, we get [tex]\mathbf{(g \ o \ f)(4)=9}[/tex]
Option C is correct
Answer:
c is correct answer

A leaking pond loses 20 gallons of water in 35 hours. How many gallons of water will it lose in 47 hours?
The senior classes at High School A and High School B planned separate trips to New York City. The senior class at High School A rented and filled 1 van and 6 buses with 372 students. High School Brented and filled 4 vans and 12 buses with 780 students. Each van and each bus carried the same number of students. How many students can a van carry? How many students can a bus carry? *
Answer:
ANSWER: each van carries 18 people and each bus can transport 59 people.
Step-by-step explanation:
Let x = number of vans
y = number of buses
Then x + 6y = 372
4x + 12y = 780
Multiply the first equation by -4: -4x - 24y = -1488
4x + 12y = 780
Adding the equations, we get -12y = -708
y = 59
Substitute for y in the equation x + 6y = 372:
x + 6(59) = 372
x + 354 = 372
x = 18

Lines j and k are parallel and cut by a transversal t. If m<1 = 4x – 20 and m<6 = 5x – 25, what is m<2?
Answer:
Step-by-step explanation:
m<2 = 5.
because if you subtract 5x from 4x and that equals -1x. then you add 20 to -25 that equals -5. then you divided -5 by the -1x and you get 5.

Step-by-step explanation:
Do multiplication first since it comes before the division in this equation
1/5 · 1/2 = 1/10
Plug this value back into the equation
1/2 - 1/10 + 2/5 ÷ 7/10
Divide 2/5 by 7/10
4/7
Plug this value back into the equation
1/2 - 1/10 + 4/7
Subtract 1/10 from 1/2
2/5
Plug this value back into the equation
2/5 + 4/7
Add.

I can't answer the first question because you need to draw lines from one number to another and I'm not sure how to type that. The answer to the second question is choice 1.
Answer:
1) draw a colored in dot right above 0 with an arrow connected to it that points to the left of the graph
2) draw a white uncolored in dot right above 12 connected to an arrow that points to the left of the graph
6) draw a colored in dot right above -4 with an arrow connected to it that points to the right of the graph
7) draw a colored in dot right above 2 with an arrow connected to it that points to the left of the graph
For question 1 on the second image, the answer is Option 1. We would color in the dot right above 36 because the child an be 36 inches and still ride the ride, and we would leave the dot right above 48 uncolored because in order to ride the ride the child must be less than 48 inches they cannot be 48 inches or taller if they want to ride the ride.
Step-by-step explanation:
The inequality for the first question can be simplified to p [tex]\leq \\[/tex] 0, so just draw a colored in dot right above 0 with an arrow connected to it that points to the left of the graph (indicating that all values of p are less than or equal to 0)
The inequality for the second equation can be simplified to g < 12, so just draw a white uncolored in dot right above 12 connected to an arrow that points to the left of the graph (indicating that all values of g are less than 12)
The inequality for the problem that says 6), can be simplified to -4 [tex]\leq \\[/tex] c, so just draw a colored in dot right above -4 with an arrow connected to it that points to the right of the graph (indicating that all values of c are equal to or greater than -4)
The inequality for the problem that says 7), can be simplified to j [tex]\geq[/tex] 2, so just draw a colored in dot right above 2 with an arrow connected to it that points to the left of the graph (indicating that all values of j are equal to or greater than 2)

A chef uses 13 pounds of sugar in 4 weeks. Find his rate of usage in pounds per week.
A dog that weighs 14 pounds should eat 1 5/8 cups of a certain type of dog food per day. How much of the same type of dog food should be fed, per day, to a dog who weighs 26 pounds?
PLEASE HELP!!!!!!!!
9514 1404 393
Answer:
3 1/56 cups
Step-by-step explanation:
Apparently, you're to assume that the amount of food is supposed to be proportional to weight. If x is the amount of food for the 26-pound dog, then ...
cups/weight = (1 5/8)/14 = x/26
Multiplying by 26 we have ...
x = (26)(13/8)/14 = 338/112 . . . cups
x = 3 1/56 cups ≈ 3.02 cups
About 3.02 cups of the same type of food should be fed to a 26-pound dog.
