Find the volume of the described solid of revolution or state that it does not exist. The region bounded by ​f(x) and the​ x-axis on the interval ​[​,​) is revolved about the​ x-axis.

Answer:

0.12

Step-by-step explanation:

This is the answer because:

1) First, rewrite the expression including the x value

1.2(0.1)

2) Next, we know 1.2 x 1 is 1.2, but since we have one decimal point in 0.1, we have to move the decimal point in 1.2 once to the left. This will make the answer 0.12

Hope this helps! :D

Answer:

Number of 13 cents stamp = 14

Number of 29 cents stamp = 24

Number of 45 cents stamp = 16

Step-by-step explanation:

We are told he has 54 stamps in total.

These stamps are;13 cent, 29 cent, and 45 cent stamps.

Let's call number of 13 cent($0.13) stamp A

Call number of 29 cent($0.29) stamp B

Call number of 45 cent($0.45) stamp C

Thus;

A + B + C = 54

We are told the total value of the 3 stamps are $15.98.

Thus;

0.13A + 0.29B + 0.45C = $15.98 - - - (eq2)

Now we are told that if the number of 13 cent stamps is doubled, the new total value of his stamp collection would be $17.80.

Thus;

2(0.13A) + 0.29B + 0.45C = 17.8

0.26A + 0.29B + 0.45C = 17.8 - - - (eq 3)

Solving the 3 equations simultaneously, we have;

A = 14

B = 24

C = 16

We have;

Number of 13 cents stamp = 14

Number of 29 cents stamp = 24

Number of 45 cents stamp = 16

The sum of the integers less than 100 that have both 6 and 9 as divisors is 270

Step-by-step explanation:

To determine the integers less than 100 that have both 6 and 9 as divisors,

First, we will list the multiples of 6 and 9 that are less than 100, and the common multiples will give the integers less than 100 that have both 6 and 9 as divisors.

Multiples of 6 less than 100 are:

6, 12, 18, 24, 30, 36, 42, 48, 54, 60, 66, 72, 78, 84, 90, and 96.

Multiples of 9 less than 100 are:

9, 18, 27, 36, 45, 54, 63, 72, 81, 90, and 99.

Hence, the integers less than 100 that have both 6 and 9 as divisors are 18, 36, 54, 72 and 90.

Then, the sum of the integers less than 100 that have both 6 and 9 as divisors is

18 + 36 + 54 + 72 + 90 = 270

Hence, the sum of the integers less than 100 that have both 6 and 9 as divisors is 270.

Answer:

0.4532

Step-by-step explanation:

Given the question :

Find the percentage of area under a normal curve between the mean and the given number of standard deviations from the mean.1.68

Number of standard deviations from the mean = 1.68

I. 68 standard deviations below the mean :

Mean = 0(normal distribution)

P(Z < 0) = 0.5

1.68 standard deviations above the mean = + 1.68

P(Z < 1.68) = 0.95352

P(0 < x < Z) = (0.95352 - 0.5) = 0.4532

Answer:

quotient less than the dividend​

Step-by-step explanation:

In this equation:

Dividend = 3/5

Divisor = 3 and

Quotient = 1/5

The question asks you to compare 3/5 to 1/5 and 3/5 is larger therefore the quotient less than the dividend​.

Answer:

7 ft per in

Step-by-step explanation:

If she has a scale where 49 feet is represented by 7 inches, then the ratio is:

49 feet to 7 inches  which can be written as:49 ft /7 in = 7 ft / in

So the scale is 7 feet per inch

Answer:

n = 10

p = 0.56

Step-by-step explanation:

The requried, there are 240 possible ways the race can finish with a mouse placing first, second, and third.

To find the number of ways the race can finish with a mouse placing first, second, and third, we can use the concept of permutations.

Since the mouse is guaranteed to finish first, there are 5 mice to choose from for the first position.

Once the first place is determined, there are 4 mice left for the second position.

After the first two positions are filled, there are 3 mice left for the third position.

Now, we need to determine the order of the cats. There are 4 cats to choose from for the fourth position.

The total number of ways the race can finish with a mouse placing first, second, and third is given by the product of these choices:

Number of ways = 5 (for first place) * 4 (for second place) * 3 (for third place) * 4 (for fourth place)

Number of ways = 5 * 4 * 3 * 4

Number of ways = 240

There are 240 possible ways the race can finish with a mouse placing first, second, and third.

Answer:

The percentage is  [tex]p = 4.55\%[/tex]

Step-by-step explanation:

From the question we are told that

 The mean is [tex]\mu = 12.1 \ ounce[/tex]

  The standard deviation is  [tex]\sigma = 0.05 \ ounce[/tex]

    The value of soda each can claims to have is  [tex]X = 12 \ ounce[/tex]

Generally the z-score is mathematically represented  as

         [tex]z = \frac{ X- \mu }{\sigma }[/tex]

=>      [tex]z = \frac{ 12-12.1 }{0.05}[/tex]

=>      [tex]z = -2[/tex]

From the z table the area under the normal  curve representing the proportion of under filled cans is

      [tex]P(x <-2 \ or\ x > 2)= 0.0455[/tex]

Converting to  percentage

       [tex]p = 0.0455 *100[/tex]

Answer: 20 dollars per ticket

Step-by-step explanation:

Divide the number 480 by 24.

480 ÷ 24 = 20

The answer is 20. Hope this helps!

Step-by-step explanation:

If 24 tickets cost $480 the cost of 1 is:

Let the unit be u

480 ÷ 24= u

[tex] \frac{480}{24} = u[/tex]

[tex]20 = u[/tex]

Step-by-step explanation:

Answer:

the dimensions that will minimize the cost are; 25.2 ft × 25.2 ft × 12.6 ft

Step-by-step explanation:

If the length, width and height of the building are represented by a, b and c, then we have:

Volume = abc

We are given volume as 8000 ft³. Thus;

abc = 8000

Top area = ab

Front area = ac

Back area = ac

End walls area = bc

We are told that cooling costs will amount to $2/ft² for its top, front, and back, and $4/ft² for the two end walls.

Thus, cooling cost equation is;

X = 2(ab) + 2(ac) + 2(ac) + 4bc + 4bc

X = 2ab + 4ac + 4bc

Now, from the volume equation where abc = 8000.

c = 8000/ab

Thus;

X = 2ab + 4a(8000/ab) + 4b(8000/ab)

X = 2ab + 32000/b + 32000/a

To minimize, we will find the a and b derivative and set the equation to zero in both cases.

Thus;

dX/da = 2b - 32000/a² = 0

2b = 32000/a² - - - eq(1)

Also;

dX/db = 2a - 32000/b² = 0

2a = 32000/b² - - - (eq 2)

Making a the subject in eq 2 gives;

a = 32000/2b²

a = 16000/b²

Putting 16000/b² for a in eq (1) gives;

2b = 32000/(16000/b²)²

2b = 32000b⁴/256000000

2b = b⁴/8000

Multiply both sides by 8000 to get;

2b × 8000 = b⁴

16000b = b⁴

Divide both sides by b to get;

16000 = b³

b ≈ 25.2 ft

Putting 25.2 for b in a = 16000/b², we have;

a = 16000/25.2²

a ≈ 25.2

Putting a and b = 25.2 in the volume equation, we have;

25.2 × 25.2 × c = 8000

c = 8000/(25.2 × 25.2)

c = 12.6 ft

Thus, the dimensions that will minimize the cost are; 25.2 ft × 25.2 ft × 12.6 ft

[tex]7.56\times 10^7\ \text{beats}[/tex]

Step-by-step explanation:

It is given that,

A person has an average heart rate of 72.0 beats/min.

We need to find how many beats does he or she have in 2.0 years, t = 2 Y

Converting years to min.

[tex]t=2\text{year}\times \dfrac{365\ \text{days}}{\text{year}}\times 24\dfrac{h}{\text{day}}\times \dfrac{60\text{min}}{\text{hour}}\\\\t=1051200\ \text{min}[/tex]

So, no of beats in 2 years is given by :

[tex]b=72\ \text{beats/min}\times 1051200\ \text{min}\\\\b=7.56\times 10^7\ \text{beats}[/tex]

Hence, the required answer is [tex]7.56\times 10^7\ \text{beats}[/tex].
