Find the area of the region that lies under the parabola y=5x - x^2, where 1≤x≤4. I would definitely like to see some work :)

Answers

Answer 1

Answer:

  16.5 square units

Step-by-step explanation:

You are expected to integrate the function between x=1 and x=4:

  [tex]\displaystyle\text{area}=\int_1^4{(5x-x^2)}\,dx=\left.\left(\dfrac{5}{2}x^2-\dfrac{1}{3}x^3\right)\right|_{x=1}^{x=4}\\\\=\dfrac{5(4^2-1^2)}{2}-\dfrac{4^3-1^3}{3}=37.5-21=\boxed{16.5}[/tex]

Additional comment

If you're aware that the area inside a (symmetrical) parabola is 2/3 of the area of the enclosing rectangle, you can compute the desired area as follows.

The parabolic curve is 4-1 = 3 units wide between x=1 and x=4. It extends upward 2.25 units from y=4 to y=6.25, so the enclosing rectangle is 3×2.25 = 6.75 square units. 2/3 of that area is (2/3)(6.75) = 4.5 square units.

This region sits on top of a rectangle 3 units wide and 4 units high, so the total area under the parabolic curve is ...

  area = 4.5 +3×4 = 16.5 . . . square units

Marcelo has 6 red marbles in his marble collection. The red marbles make up 12% of all the marbles. How many marbles are in Marcelo’s collection? Show your work.

Answers

If 6/? makes of 12/100, we need to divid 100 by two to figure out the denominator of six. This is because to go from 12 to six (the numerators), you divide by two, so you do it for the denominator as well. This would give 6/50, which means there are 6 red marbles out of 50 marbles in the collection.

The total number of marbles in Marcel's collection is 50.

What is the percentage?

The percentage is defined as representing any number with respect to 100. It is denoted by the sign %. The percentage stands for "out of 100." Imagine any measurement or object being divided into 100 equal bits.

Given that Marcelo has 6 red marbles in his marble collection. Red marbles make up 12% of all the marbles.

The number of marbles in Marcel's collection is calculated as,

12% of marbles = 6

1% of marbles = 6 / 12

100% of the marbles= ( 6 / 12) x 100

100% of the marbles = 50

A town has a population of 2000 and grows at 4. 5% every year. What will be the population after 13 years, to the nearest whole number?.

Answers

Answer:

3544 people

Step-by-step explanation:

We can start by representing this as an exponential function, in the form [tex]y=a(b)^x[/tex]

2000 will be our a, or our initial value. We must convert our multiplier, 4.5% to a decimal, which is 1.045. 13 is our input since it's our number of years where we want to find the population. Now that we have our variables, lets make an equation.

[tex]y=2000(1.045)^13[/tex]

PEMDAS states that we first do exponents, so lets raise 1.045 to the 13th power.

[tex]y=2000(1.77219609724)[/tex]

Now we multiply by 2000!

[tex]y= 3544.39219448[/tex]

Rounded to the nearest whole number is 3544. Therefore, there will be 3,544 people living in the town in 13 years.

For this activity, you will need two coins.
First, you will determine the theoretical probability of events.
Then, you will flip the coins 100 times and determine the experimental probability of the events.

Flip two coins 100 times, and record the results of each coin toss in a table like the one below:

Result

Two Heads
28
Two Tails
30
1 Head, 1 Tail
42

Answer the following questions based on the data you gathered. You must show your work to receive credit.

1. What is the theoretical probability that a coin toss results in two heads showing?

2. What is the experimental probability that a coin toss results in two heads showing?


3. What is the theoretical probability that a coin toss results in two tails showing?

4. What is the experimental probability that a coin toss results in two tails showing?


5. What is the theoretical probability that a coin toss results in one head and one tail showing?


6. What is the experimental probability that a coin toss results in one head and one tail showing?


7. Compare the theoretical probabilities to your experimental probabilities. Why might there be a difference?

Answers

1. The theoretical probability that a coin toss results in two heads showing is 25% :

The probability of a head showing the first time is 50%
The probability of getting a head twice is 50% x 50% = 25%

2. The experimental probability that a coin toss results in two heads showing is 28/100 (28%)

3. The theoretical probablity that a coin toss results in two tails showing is 25% ( 50% x 50% )

4. The experimental probability that a coin toss results in two tails showing is 30/100 (30%)

5. The theoretical probability that a coin toss results in one head and one tail showing is 25% (also 50% x 50%)

6. The experimental probability that a coin toss results in one head and one tail showing is 42/100 (42%)

7. The theoretical probabilities have a difference from experimental probabilities because theoretical probabilities are equal odds of happening, while experimental probabilities might be biased because we might get tails for example, 10 times in a row, which messed up the odds.

Answer:

Question 1: C. 4 × 3 × 2 ×  [tex]\frac{1}{8}[/tex]  × [tex]\frac{1}{8}[/tex]  × [tex]\frac{1}{8}[/tex]

Question 2: The volume is [tex]\frac{1}{12}[/tex] or 0.083333333

Question 3: The volume fo the solid figure is 234

Step-by-step explanation:

1. Volume of a rectangular prism = (length × width × height) cubic units

Length = 4 ×  [tex]\frac{1}{8}[/tex]

Width = 3 × [tex]\frac{1}{8}[/tex]

Height = 2 × [tex]\frac{1}{8}[/tex]

Volume = 4 ×  [tex]\frac{1}{8}[/tex] × 3 × [tex]\frac{1}{8}[/tex]  × 2 × [tex]\frac{1}{8}[/tex]

Volume = 4 × 3 × 2 ×  [tex]\frac{1}{8}[/tex]  × [tex]\frac{1}{8}[/tex]  × [tex]\frac{1}{8}[/tex]

So the correct option is:

C. 4 × 3 × 2 ×  [tex]\frac{1}{8}[/tex]  × [tex]\frac{1}{8}[/tex]  × [tex]\frac{1}{8}[/tex]

2.

We have to fold the shape into a rectangular prism, look at the picture

Volume of a right rectangular prism =  (length × width × height)

Length = [tex]\frac{1}{3}[/tex]

Width =  [tex]\frac{1}{3}[/tex]

Height = [tex]\frac{3}{4}[/tex]

Volume = [tex]\frac{1}{3}[/tex] ×  [tex]\frac{1}{3}[/tex]  ×  [tex]\frac{3}{4}[/tex]

Multiply [tex]\frac{1}{3}[/tex] times [tex]\frac{1}{3}[/tex] by multiplying numerator times numerator and denominator times denominator.

[tex]\dfrac{ 1 \times 1 }{ 3 \times 3 } \times \left( \dfrac{ 3 }{ 4 } \right)[/tex]

Do the multiplications in the fraction [tex]\dfrac{ 1 \times 1 }{ 3 \times 3 }[/tex]

[tex]\dfrac{ 1 }{ 9 } \times \left( \dfrac{ 3 }{ 4 } \right)[/tex]

Multiply [tex]\frac{1}{9}[/tex] times [tex]\frac{3}{4}[/tex] by multiplying numerator times numerator and denominator times denominator.

[tex]\dfrac{ 1 \times 3 }{ 9 \times 4 }[/tex]

Do the multiplications in the fraction [tex]\dfrac{ 1 \times 3 }{ 9 \times 4 }[/tex]

[tex]\frac{3}{36}[/tex]

Reduce the fraction [tex]\frac{3}{36}[/tex] to the lowest terms by extracting and canceling out 3

Fraction form: [tex]\frac{1}{12}[/tex]

or

Decimal form: 0.083333333

So the volume of the right rectangular prism is [tex]\frac{1}{12}[/tex]

3. Look at the picture with the solid figure labeled

We can think of this shape as two different prisms ( A and B)

Volume of A = 4.5 × 6 × 6.5 = 175.5

Volume of B = 3 × 3 × 6.5 = 58.5

Total volume of the whole figure = 175.5 + 58.5

175.5 + 58.5 = 234

So the volume of the solid figure is 234

Hii! Goodafternoon/morning!

Your question is asking how much is 3/8 + 3/8 + 3/8 is.

Normally, we would find a common denominator. But since they are all the same fraction, we don't need to.

First we need to figure out what 6×3 equals. That is 18.

We can't multiply 6×8.

So

We have to write the fraction has

18/8

But thats not simplified. So we need to turn this into a mixed number.

18/8 simplified is 2 2/8

We need to simplify that again.

2 2/8 simplified is 2 1/4.

So the answer is

2 and 1/4.

CAN SOMEONE GIVE A EXPLAINATION ABOUT CLOSURE PROPERTY WITH A SIMPLE EXAMPLE THAT IS EASY TO UNDERSTAND

Answers

Explanation:

A set is "closed" for a particular operation if performing that operation on members of the set always gives a member of the set.

closed example

For example, the set {0, 1} is closed for multiplication:

  0 × 0 = 0

  0 × 1 = 0

  1 × 1 = 1 . . . all result values are members of the set

Performing multiplication on any two members of the set gives a member of the set.

__

not closed example

The same set {0, 1} is not closed for addition:

  0 +0 = 0

  0 +1 = 1

  1 +1 = 2 . . . not a member of the set

Performing addition on any two members of the set does not always give a member of the set.

Additional comment

Sometimes you are asked to demonstrate closure of a particular set using a particular example. As we see with addition, above, some examples may seem to demonstrate closure, while another example may prove the set is not closed. In short, you can demonstrate that the set is closed for a particular operation on a particular example, but that does not demonstrate closure in general.

did the video get over the course of the first 13 days, to the nearest whole number?

Answers

Answer:

The answer is 7212 views

Step-by-step explanation:

Given;A music video got 390 views.The number of views that the video got each day increased by 30% per day.To Find;Total views did the video get over the course of the first 13 days

So, For the first day the number of views is 390

Second Day

30% increased of total views

390 × 30 ÷ 100 = 11.7 = 12

390 + 12 = 402

Third Day

30% increased of total views

402 × 30 ÷ 100 = 120.6 = 121

402 + 121 = 523

Fourth Day

30% increased of total views

523 × 30 ÷ 100 = 156.9 = 157

523 + 157 = 680

Fifth Day

30% increased of total views

680 × 30 ÷ 100 = 204

680 + 204 = 884

Sixth Day

30% increased of total views

884 × 30 ÷ 100 = 265.2 = 265

884 + 265 = 1149

Seventh Day

30% increased of total views

1149 × 30 ÷ 100 = 344.7 = 345

1149 + 345 = 1494

Eight Day

30% increased of total views

1494 × 30 ÷ 100 = 448.2 = 448

1494 + 448 = 1942

Ninth Day

30% increased of total views

1942 × 30 ÷ 100 = 582.6 = 583

1942 + 583 = 2525

Tenth Day

30% increased of total views

2525 × 30 ÷ 100 = 757.5 = 758

2525 + 758 = 3283

Eleventh Day

30% increased of total views

3283 × 30 ÷ 100 = 984.9 = 985

3283 + 985 = 4268

Twelth Day

30% increased of total views

4268 × 30 ÷ 100 = 1280.4 = 1280

4268 + 1280 = 5548

Thirteenth Day

30% increased of total views

5548 × 30 ÷ 100 = 1664.4 = 1664

5548 + 1664 = 7212

Thus, Total views did the video get over the course of the first 13 days is 7212 Views.
