Answer:

The volume of the cylinder is 9.42ft³

Step-by-step explanation:

radius = half of diameter

r = 2ft /2 = 1ft

To calculate the volume of a cylinder we have to use the following formula:

v = volume

h = height = 3ft

π = 3.14

r = radius = 1ft

v = (π * r²) * h

we replace with the known values

v = (3.14 * (1ft)²) * 3ft

v = (3.14 * 1ft²) * 3ft

v = 3.14ft² * 3ft

v = 9.42ft³

The volume of the cylinder is 9.42ft³

Final answer:

To double Rahul's savings of $3,000 to $6,000 in six years through compound interest, the required annual interest rate is approximately 12.25%.

Explanation:

The student wants to determine the interest rate needed for his savings to grow from $3,000 to $6,000 over a period of six years with compound interest compounded annually. We can use the formula for compound interest: A = P(1 + r)^n, where A is the amount of money accumulated after n years, including interest, P is the principal amount (initial sum of money), r is the annual interest rate, and n is the number of years the money is invested for.

To solve this, use the formula with A = $6,000, P = $3,000, and n = 6 years, and then solve for r:

6,000 = 3,000(1 + r)⁶

Dividing both sides by 3,000:

2 = (1 + r)⁶

Now we must take the sixth root of both sides to solve for (1 + r):

(1 + r) = √⁶(2)

Then subtract 1 from both sides to solve for r:

r = √⁶(2) - 1

Using a calculator, simply compute the sixth root of 2, subtract 1, and convert to percentage to find the required interest rate:

r = 0.122462… or 12.2462%

Therefore, the interest rate required is approximately 12.25%.

Answer:

2.3 feet/ second

Step-by-step explanation:

To find the rate of change, we will have to find the difference in his distance travelled and divide it by the time taken to move that distance.

This is given by rate of change = (change in position)/ change in time

From the question, his position changed from 30 ft to 100 ft thus the distance he travelled is = 100ft - 30 ft = 70 ft.

Time taken to travel this distance = 40 seconds - 10 seconds = 30 seconds

Diver's rate of travel = 70 ft / 30 seconds = 2.33333ft/second.

Rounding off the answer to the nearest tenth, we have 2.3 ft/second

The graph shows an inverse relationship between the price of graphic t-shirts and the quantity demanded. As the price decreases, the quantity demanded increases, and vice versa. The demand for graphic t-shirts is elastic, meaning changes in price have a significant impact on the quantity demanded.

The graph shows the relationship between the price of graphic t-shirts and the quantity demanded. In general, as the price of the t-shirts decreases, the quantity demanded increases, and vice versa. This is known as the law of demand, which states that there is an inverse relationship between price and quantity demanded.

For example, if the price of a graphic t-shirt is $20, the quantity demanded might be 100. But if the price decreases to $15, the quantity demanded might increase to 150.

By analyzing the demand curve shown in the graph, we can see that the demand for graphic t-shirts is elastic. This means that changes in price have a significant impact on the quantity demanded.

a. Write a linear equation that describes the problem

b. Graph the linear equation.

c. If the team sells 50 tickets,  how many snacks does it  need to sell to reach the  goal?

Answer:

a.15x+6y= 900

b. The graph is attached.

c. 25

Step-by-step explanation:

a. From the information provided, the linear equation has to express that the number of tickets multiply for its price plus the number of snacks multiply for its price would be equal to $900:

15x+6y= 900

x= number of tickets

y= number of snacks

b.

When x= 0:

15(0)+6y= 900

y=900/6= 150

When y=0

15x+6(0)= 900

x=900/15= 60

With these points, you can graph the linear equation and the image is attached.

c. You have to replace the value of x in the equation and isolate y:

15x+6y= 900

15(50)+6y= 900

750+6y=900

6y= 900-750

6y= 150

y= 150/6

y= 25

You need to sell 25 snacks to reach the goal.

Step-by-step explanation:

There are two general types of sequences that follow a pattern, geometric and arithmetic. Let's see the difference between the two:

An arithmetic sequence is produced by adding the same number to all the terms in the sequence.

EXAMPLE:

5, 7, 9, 11, 13, 15, 17 (The number 2 is added to all terms)

To figure out if a sequence is arithmetic, subtract the first term from the second, then the second from the third and so on until you have checked all the terms.

7 - 5 = 2

9 - 7 = 2

11 - 9 = 2

13 - 11 = 2

15 - 13 = 2

17 - 15 = 2

All results equal 2, so the sequence is arithmetic

From your list: The following sequences are arithmetic

A. 5, 10, 15, 20, 25 (common difference of 5)

The next type of sequence is the geometric sequence.

A geometric sequence is produced when the all the terms in the sequence are multiplied or divided by the same number.

EXAMPLE:

100, 50, 25 (Each term is divided by 2)

To figure this out, we divide each term in the sequence by the next term.

100 / 50 = 2

50 / 25 = 2

All results are two, so this sequence can be confirmed to be geometric

From your list: The following sequences are geometric

C. 10, 5, 2.5, 1.25, 0.625, 0.3125 (common quotient of 2)

D. -9, -3, -1, -1/3, -1/9, -1/27 (common quotient of -3)

There is one final type of sequence, which has no common difference, sum, quotient, or product.

EXAMPLE:

5, 6, 8, 9, 11, 12, 14, 15

This sequence has a pattern, the differences between the numbers are not common.

6 - 5 = 1

8 - 6 = 2

9 - 8 = 1

11 - 9 = 2

12 - 11 = 1

14 - 12 = 2

15 - 14 = 1

From your list: The following sequences are neither geometric nor arithmetic

B. 1, 1, 2, 3, 5, 8, 13 (No pattern)

I'n always happy to help :)

The correct sequences which are geometric sequence is,

C) 10, 5, 2.5, 1.25, 0.625,

D) - 9, - 3, - 1, - 1/3, - 1/9, - 1/27

An sequence has the ratio of every two successive terms is a constant, is called a Geometric sequence.

Given that;

All the sequences are,

A) 5, 10, 15, 20, 25

B) 1, 1, 2. 3, 5, 8, 13

C) 10, 5, 2.5, 1.25, 0.625,

D) - 9, - 3, - 1, - 1/3, - 1/9, - 1/27

Now, We know that;

Common ratio of the geometric sequences are same.

Hence, We get;

A) 5, 10, 15, 20, 25

Common ratio = 10/5 = 2

Common ratio = 15/10 = 3/2

Hence, It is not geometric sequence.

B) 1, 1, 2. 3, 5, 8, 13

Common ratio = 1/1 = 1

Common ratio = 2/1 = 2

Hence, It is not geometric sequence.

C) 10, 5, 2.5, 1.25, 0.625,

Common ratio = 5/10 = 1/2

Common ratio = 2.5/5 = 1/2

Hence, It is geometric sequence.

D) - 9, - 3, - 1, - 1/3, - 1/9, - 1/27

Common ratio = - 3/- 9 = 1/3

Common ratio = - 1/- 3 = 1/3

Hence, It is geometric sequence.

Thus, The correct sequences which are geometric sequence is,

C) 10, 5, 2.5, 1.25, 0.625,

D) - 9, - 3, - 1, - 1/3, - 1/9, - 1/27

Answer:

The volume of the cylinder is 25.12

Step-by-step explanation:

The width is the diameter in the circle of the base

radius = half of diameter

To calculate the volume of a cylinder we have to use the following formula:

v = volume

h = height = 8

π = 3.14

r = radius = 1

v = (π * r²) * h

we replace the unknowns with the values we know

v = (3.14 * (1)²) * 8

v = (3.14 * 1) * 8

v =3.14 * 8

v = 25.12

Rounding up to the nearest degree is equivalent to rounding up to the nearest whole number (or integer)

Step-by-step explanation:

Any value between degrees above .5 is rounded up to the next degree, so for instance:

30.4 --> 30

30.5 --> 31

30.999 --> 31

31 --> 31

31.499 --> 31

Rounding values expressed in degrees and minutes is similar to rounding decimals.

Rounding numbers refers to changing a number's digits such that it approximates a value. The provided number is more simply represented by this value. For instance, 700,000 rather than 698,869 could be used to express a town's population.

We know that;

Rounding values expressed in degrees and minutes is similar to rounding decimals.

However, because there are 60 minutes in a degree, the half way point is 30. If the number of minutes is less than 30, we round down to the nearest degree. If the number of minutes is 30 or more, we round up to the nearest degree.

The pressure P as a function of time t can be modeled using the sine function. The maximum pressure is 5 millipascals. The wavelength, frequency, and speed of the sound wave can be calculated using formulas.

The sine model that gives the pressure P as a function of time t is:

P(t) = 5 millipascals * sin(2π * 1200 * t)

Maximum change in pressure: The maximum change in pressure is 5 millipascals.

Wavelength: The wavelength of the sound wave can be calculated using the formula: wavelength = speed / frequency. Since the speed of sound in air is approximately 343 meters per second, the wavelength is approximately 0.285 meters.

Frequency: The frequency of the sound wave is 1200 hertz (cycles per second).

Speed of the sound wave: The speed of the sound wave can be calculated using the formula: speed = wavelength * frequency. Using the values we have, the speed of the sound wave is approximately 343 meters per second.

Final answer:

The sine model that gives the pressure P as a function of time t for an audiometer producing a pure tone at 1200 Hz with a maximum pressure of 5 millipascals is P(t) = 5 · sin(2π · 1200t).

Explanation:

To write a sine model that gives the pressure P as a function of the time t for a sound wave produced by an audiometer, we can use the standard form of a sine function for a periodic wave:

P(t) = Pmax · sin(2πft + φ)

Since we are given that Pmax is 5 millipascals, the frequency f is 1200 hertz, and P=0 when t=0 (which implies that the initial phase shift φ is zero), we can plug these values into the sine model to get:

P(t) = 5 · sin(2π · 1200t)

Here, we converted the maximum pressure from millipascals to pascals, and since the sine of 0 is 0, we have a phase shift of 0 radians, simplifying the equation.
