2x3 - 2x + 1/x2 - 2x dx

Answers

Answer 1

Answer:

[tex]x^2+4x -\frac{1}{2} lnx + \frac{2}{13} ln(x-2) + C[/tex]

Step-by-step explanation:

Given the integrand [tex]\int\limits{\dfrac{2x^3 - 2x + 1}{x^2-2x} } \, dx[/tex], before evaluating the integral function, we will need to simplify the function first by applying long division as shown in the attachment.

Hence the partial form of the function [tex]\dfrac{2x^3 - 2x + 1}{x^2-2x} } = 2x+4 + \frac{6x+1}{x^2-2x}[/tex]

Integrating its partial sum

[tex]\int\limits \dfrac{2x^3 - 2x + 1}{x^2-2x} }dx = \int\limits (2x+4 + \frac{6x+1}{x^2-2x})\ dx\\\\= \int\limits {2x} \, dx + \int\limits {4} \, dx + \int\limits {\frac{6x+1}{x^2-2x} \, dx\\ = \frac{2x^2}{2}+4x -\frac{1}{2} \int\limits{\frac{1}{x} } \, dx + \frac{2}{13} \int\limits{\frac{1}{x-2} } \, dx[/tex]

[tex]= \frac{2x^2}{2}+4x -\frac{1}{2} lnx + \frac{2}{13} ln(x-2) + C[/tex]

[tex]= x^2+4x -\frac{1}{2} lnx + \frac{2}{13} ln(x-2) + C[/tex]

Point A (2, 6) has been translated 1 left and 3 up followed by a 180 degree rotation.

What is the image of Point A?

Answers

Answer:

[tex]A(-1,-8)[/tex]

Step-by-step explanation:

Given

Point: A(2,6)

Translation: 1 left and 3 up

Rotation: 180 degrees

Required

Image of Point A

Taking the exercise one after the other

Represent the function as: (x,y)

Such that

[tex]A(x,y) = A(2,6)[/tex]

1 unit left translation means the function becomes (x - 1, y)

2 unit up translation means the function becomes (x - 1, y + 2)

Applying the above transformation

[tex]A(2,6) -> A(2-1,6+2)[/tex]

[tex]A(2,6) -> A(1,8)[/tex]

At this stage, the coordinate becomes

[tex]A(1,8)[/tex]

When a function (x,y) is rotated by 180, the new function becomes (-x,-y)

So;

The further transformation of A is

[tex]A(1,8) -> A(-1,-8)[/tex]

Hence, the new image of A is

[tex]A(-1,-8)[/tex]

Step-by-step explanation:

Step(i):-  

By using Ratio test

                [tex]\lim_{n \to \infty} |\frac{a_{n+1} }{a_{n} } | = l[/tex]

a)     [tex]\lim_{n \to \infty} |\frac{a_{n+1} }{a_{n} } | = l[/tex]  

'l' is finite then the given ∑aₙ is convergent

b)   [tex]\lim_{n \to \infty} |\frac{a_{n+1} }{a_{n} } | = l[/tex]  

Here 'l' is infinite then the  ∑aₙ  is divergent

Step(ii):-

Given      aₙ = [tex]\frac{n!}{n}[/tex]

            [tex]a_{n+1} = \frac{(n+1)!}{n+1}[/tex]

     [tex]\lim_{n \to \infty} |\frac{a_{n+1} }{a_{n} } | = \lim_{n \to \infty} |\frac{\frac{(n+1)!}{n+1} }{\frac{n!}{n} } |[/tex]

               we know that  n ! = n (n-1) (n-2) ......3.2.1

              and also          (n+1) ! = (n+1)n!

  [tex]\lim_{n \to \infty} |\frac{a_{n+1} }{a_{n} } | = \lim_{n \to \infty} |\frac{\frac{n+1)n!}{n+1} }{\frac{n!}{n} } |[/tex]

A dog spots a cat 50 feet away and starts to chase it. At the same moment, the cat starts to run away from the dog. The dog is running 12 feet per second and the cat is running 10 feet per second. Let t represent the time elapsed (in seconds) since the chase began. Let d represent the distance between the cat and the dog (in feet) Write a formula to define the distance between them (d) in terms of the time elapsed (t).

Answers

Answer:

D(t) = 50 -2t

At 25 seconds, the dog caught up with the cat

Step-by-step explanation:

At initial time t0

Distance = 50 ft

The dog is running 12 feet per second and the cat is running 10 feet per second.

So for each each time in seconds

Dog covers 12 feet while cat extends by 10 ft .

The distance between them at any given time

D(t)= 50 +10t -12t

D(t) = 50 -2t

The time it will take the dig to get to the cat is what D= 0

D(t) = 50 -2t

0= 50- 2t

2t= 50

t= 25

So at 25 seconds, the dog caught up with the cat

A drone carrying fireworks is launched from a platform above a lake and follows a parabolic path. It will set off the fireworks at its highest point. The drone’s height above the surface of the lake is given by the function h(t) = -16t2 + 64t + 80, where h represents height in feet and t represents time in minutes. a. How high is the platform? b. From what height will the fireworks be released? c. When does the drone land?

Answers

Yes it is true that’s the answer

Answer: Answer is in the steps

Step-by-step explanation:

using the function h(t) = -16t^2 + 64t + 80    and H is height in feet  t is the time in minutes we can evaluate how high the platform is by solving for the y intercept.

h(t) = -16t^2 + 64t + 80  the y intercept is when h(t) is h(0)  so when it is h of zero  put zero into the function and solve the function

A) -16(o)^2 + 64(0) + 80  

      0 -0  + 80

    h(0) =  80  

Which means the platform is 80 feet high.  

B) In the reading it says that it will set the firework at its highest point  and in other words its highest point is its vertex. So solve for the vertex .

   h(t) = -16t^2 +64t + 80       To solve for the vertex, use the formula x= -b/2a  to find the x coordinate of the vertex.

     so  the value of b is 64  and a is -16 .

 x = -64 / -32    

x = 2

 So the x coordinate of the vertex is 2  so input it and solve for the y coordinate of the vertex.

h(t) = y =  -16(2)^2 + 64t+80

y=   -16(4) + 64(2)+ 80  

  y=   -64 + 128 + 80

      y = 144  

So the y coordinate is 144. which means the vertex  is (2,144) and also means that the fireworks will be released at  a 144 feet.

 C)  The drone will land on the ground when they is not height which means when  y is equal to zero or h(t)  is zero.  

          -16t^2 +64t + 80 = 0       so solve for t using the quadratic formula.

The quadratic formula says that  x= -b ± [tex]\sqrt{b^2 -4ac} /2a[/tex]  

   a = -16     b= 64   and c= 80  

 x = -64 + [tex]\sqrt{9216}/ -32[/tex]  

 x= -64 ± 96 /-32  

  x=  -1   or  x = 5

    Which means the drone land on the ground in 5 minutes. It can't be -1 because a negative number can't represent time.

In a race, there are 20 runners. Trophies for the race are awarded to the runners
finishing in first through fourth place.
In how many ways can first through fourth place by determined?

Answers

Answer:

116,280 ways

Step-by-step explanation:

Because your finish place is mutually exclusive (if you come in first you cant come in second, if you come in second you cant come in third, etc) you have to decrease the amount of runners for each place.

20 runners can get first

19 for second

18 for third

17 for fourth.

To find out the total amount of possibilities you multiply each amount. 20 x 19 x 18 x 17 = 116,280.

A student currently is averaging 65.0% of the points in lecture (worth 60% of total grade) and has a 75.0% in lab (worth 40% of total grade). What is her total course % at this time?

Answers

Answer:

69

Step-by-step explanation:

If she is averaging 65% of the worth of lectures.

the lectures she had was supposedly rated out of 60. Therefore, the 65% will be 65% of 60(total grade)

0.65 * 60 = 39

On the second part, if we apply the same method, we have

0.75 * 40 = 30

All we have to do on add both together

39 + 30 = 69.

therefore, get total grade in the course is 69

Total grade in the course is 69%

Percentage :

Since,  the averaging 65% of the points in lecture is worth to 60% of total grade.

It means that, the 65% will be equivalent to,

                  [tex]=\frac{60*65}{100}=3900/100=39[/tex] percent of total grade.

And 75% in lab is worth 40% of total grade.

             [tex]=\frac{75*40}{100}=30[/tex] percent of total grade.

We have to add both together

            [tex]39 + 30 = 69.[/tex]

Shelley compared the number of oak trees to the number of maple trees as part of a study about hardwood trees in a woodlot. She counted 9 maple trees to every 5 oak trees. Later in the year there was a bug problem, and many trees died. New trees were planted to make sure there were the same number of trees as before the bug problem. The new ratio of the number of maple trees to the number of oak trees is 3:11. After planting new trees, there were 132 oak trees. How many more maple trees were in the woodlot before the bug problem than after the bug problem?

Answers

Answer:

72

Step-by-step explanation:

Initial ratio of maple trees to oak trees

9:5

New ratio  of maple trees to oak trees

3:11

Number of oak trees = 132

Number of maple trees

132*3/11 = 36

Total number of trees

132+36 = 168

Initial number of maple trees

168*9/14 = 108

The difference in the number of maple trees:

108 - 36 = 72

Answer:

72 more trees before the bug problem

Step-by-step explanation:

The ratio was 9:5 before the bug problem and 3:11 after.

After the bug problem there were 132 oak trees,

m : 132 = 3 : 11

Then we know

m/132 = 3/11

Multiplying both sides by 132 cancels on the left

132 × (m/132) = (3/11) × 132

m = (3/11) × 132

Then solving for m

m = 132 × (3/11)

m = 36   This gives us the number of trees after the bug problem.

This would give us 168 trees in total, 132 oak, and 36 maple.

Since there is the same number of trees as before we calculate the number of maple and oak previously.

If Shelley counted 9 maple for every 5 oak we know that 9 out of 14 trees are maple and 5 out of 14 trees are oak.

9/14 = .6428 which is the percentage of maple trees before the bug problem.

We multiply .6428 x 168 (the total number of trees) and we get 108.

if there are 108 maple trees then 168-108 = 60 oak trees.

Further proof:

9:5 or 9/5 = 1.8     108/60 = 1.8

108 maple trees and 60 oak before the bug problem.

So 108 (maple before bug problem) and 36 maple trees after:

108 - 36 = 72 more trees before the bug problem

He was so poor that he could only earn his living by laboring day and night. One night, extremely late, he lay down to rest. He was exhausted, dejected, and sick at heart. He fell into a deep sleep and dreamt that a wise old soul came to him and said, "Your fortune is in the city of Beijing; go there and seek it." The next day, he set out for Beijing. He arrived there deep into the night and he lay down to sleep for a bit in a hostel. Presently, as fate would have it, a company of thieves entered the hostel. They made their way into the house that adjoined the hostel. Soon, the people of the house, aroused by the noise, awoke and cried out, "thieves, thieves!" An alarm was raised and the chief of the police came to their aid with his officers. The robbers made off; but the police entered the hostel and found the man from Chongqing asleep there. They cast him into prison, where they kept him for three days. The chief of police sent for him and said, "Where did you come from?" "From Chongqing," whispered the man. "And what brought you to Beijing?" asked the chief. "I saw in a dream an old soul who said to me, 'Thy fortune is at Beijing; go there at once to find it.' But, when I came here, the fortune that I was promised proved to be an arrest and a jail stay." The chief of the police laughed until he showed his white, wide, broad teeth. He said to the man from Chongqing, "O man of little wit! Three times have I seen an old soul in a dream who said to me, 'There is a fashionable house in Chongqing, with a fountain in the front garden. Under the fountain there is buried treasure a great sum of money. Go there and take it.' Of course I did not go. You, on the other hand, you of little wit, have journeyed from place to place, on the faith of a dream, which was but an illusion of sleep." Then the chief of police gave the man from Chongqing money, saying, "This is to help you get back to your native land." Now, the house that the chief described was the man's very own house in Chongqing! When he traveled home, he immediately dug underneath the fountain in his garden and discovered a great treasure!
