Given:

Radii of two spheres are 3 cm and 4.5 cm  respectively.

Surface  area of the smaller sphere is  367 cm.

To find:

The surface area of the larger sphere.

Solution:

We know that, area of similar spheres is proportional to the square of there radii.

\(\dfrac{A_1}{A_2}=\dfrac{(r_1)^2}{(r_2)^2}\)

On substituting the values, we get

\(\dfrac{367}{A_2}=\dfrac{(3)^2}{(4.5)^2}\)

\(\dfrac{367}{A_2}=\dfrac{9}{20.25}\)

On cross multiplication, we get

\((367)(20.25)=9A_2\)

\(7431.75=9A_2\)

Divide both sides by 9.

\(\dfrac{7431.75}{9}=A_2\)

\(825.75 =A_2\)

Therefore, the area of larger sphere is 825.75 cm².

Note: All options are incorrect.

The sinusoidal function that satisfies the given attributes is f(x) = 10 * sin(2π/5 * x - π/5) + 31.

To find a sinusoidal function with the given attributes, we can use the general form of a sinusoidal function:

f(x) = A * sin(Bx + C) + D

where A represents the amplitude, B represents the frequency (related to the period), C represents the phase shift, and D represents the vertical shift.

Amplitude: The given amplitude is 10. So, A = 10.

Period: The given period is 5. The formula for period is P = 2π/B, where P is the period and B is the coefficient of x in the argument of sin. By rearranging the equation, we have B = 2π/P = 2π/5.

Midline: The given midline is y = 31, which represents the vertical shift. So, D = 31.

f(3) = 41: We are given that the function evaluated at x = 3 is 41. Substituting these values into the general form, we have:

41 = 10 * sin(2π/5 * 3 + C) + 31

10 * sin(2π/5 * 3 + C) = 41 - 31

10 * sin(2π/5 * 3 + C) = 10

sin(2π/5 * 3 + C) = 1

To solve for C, we need to find the angle whose sine value is 1. This angle is π/2. So, 2π/5 * 3 + C = π/2.

2π/5 * 3 = π/2 - C

6π/5 = π/2 - C

C = π/2 - 6π/5

Now we have all the values to construct the sinusoidal function:

f(x) = 10 * sin(2π/5 * x + (π/2 - 6π/5)) + 31

Simplifying further:

f(x) = 10 * sin(2π/5 * x - 2π/10) + 31

f(x) = 10 * sin(2π/5 * x - π/5) + 31

Therefore, the sinusoidal function that satisfies the given attributes is f(x) = 10 * sin(2π/5 * x - π/5) + 31.

The correct values for a, b, c, d, and e are a = 16, b = 29, c = 24, d = 22, and e = 30 for group of 75 students on asking whether they like Algebra or Geometry.

For the values of a, b, c, d, and e, we can use the information provided in the table. Let's break it down step-by-step:

We are given that a total of 75 math students were surveyed. Therefore, the total number of students should be equal to the sum of the students who like algebra, the students who like geometry, and the students who do not like either subject.

75 = 45 (Likes Algebra) + 53 (Likes Geometry) + 6 (Does Not Like Either)

Simplifying this equation, we have:

75 = 98 + 6

75 = 104

This equation is incorrect, so we can eliminate options c and d.

Now, let's look at the information given for the students who do not like geometry. We know that a + b = 6, where a represents the number of students who like algebra and do not like geometry, and b represents the number of students who do not like algebra and do not like geometry.

Using the correct values for a and b, we have:

16 + b = 6

b = 6 - 16

b = -10

Since we can't have a negative value for the number of students, option a is also incorrect.

The remaining option is option e, where a = 29, b = 16, c = 24, d = 22, and e = 30. Let's verify if these values satisfy all the given conditions.

Likes Algebra: a + c = 29 + 24 = 53 (Matches the given value)

Does Not Like Algebra: b + d = 16 + 22 = 38 (Matches the given value)

Likes Geometry: c + d = 24 + 22 = 46 (Matches the given value)

Does Not Like Geometry: b + e = 16 + 30 = 46 (Matches the given value)

All the values satisfy the given conditions, confirming that option e (a = 29, b = 16, c = 24, d = 22, and e = 30) is the correct answer.

In conclusion, the expected running time for generating random numbers p and g can be expressed as a function of m and t as follows:

\(O((1/(m ln(2))) * (m^3t)) = O(m^2t/ln(2))\)

The expected time for generating the prime number p depends on the probability of q being prime and the number of iterations required to find a Sophie Germain prime. Since q is an m-bit integer, the probability of q being prime is approximately \(1/ln(2^m) = 1/(m ln(2)).\)

The cost of performing Miller-Rabin primality testing on a composite number N is O(\(m^3t\)) time, as stated in the problem. Therefore, the expected time to find a prime q is proportional to the number of iterations required, which is 1/(m ln(2)).

Finding a primitive element g within the range 1 ≤ g ≤ p-1 involves randomly selecting integers and checking if they satisfy the condition. Since this step is independent of the primality testing, its time complexity is not affected by the value of t. Therefore, the expected time to find a primitive element g is not directly influenced by t.

Zero-point energy is the lowest energy state of a quantum system at absolute zero temperature.

Zero-point energy is the lowest energy state of a quantum system at absolute zero temperature. To calculate the zero-point energy, the energy of the system must first be determined at the lowest temperature that can be achieved in practice, typically close to absolute zero. The energy at this temperature is then subtracted from the energy of the system at higher temperatures. This difference is the zero-point energy. The zero-point energy can be calculated by taking the sum of the energies of all of the quantum states at absolute zero. This sum can be approximated using the uncertainty principle and the Heisenberg Uncertainty Principle. The sum is then multiplied by Planck's constant to get a value for the zero-point energy. Finally, the total zero-point energy is the sum of the individual zero-point energy values of each quantum state. This energy represents the energy of the system at absolute zero and is the lowest energy state possible.

Answer:

The college student can spend $15.00 in December.

Step-by-step explanation:

This can be calculated as follows:

Let y represents the amount to spend in December.

The can now us the formula for calculating a mean is as follows:

Mean = Sum of montlhy spending / Number of months ...... (1)

From the question, we have:

Mean = $50

Sum of monthly spending = $100 + $25 + $80 + $30 + y = $235 + y

Number of months = 5

Substituting the values into equation (1) and solve for y, we have:

$50 = ($235 + y) / 5

$50 * 5 = $235 + y

$250 = $235 + y

$250 - $235 = y

$15.00 = y

Therefore, the college student can spend $15.00 in December.

The conversion of 46.32° to the D°M'S" format is 46° 19.2' 12".

To convert the angle 46.32° to the D°M'S" format, we start by considering the whole number part, which is 46°. This represents 46 degrees.

Next, we convert the decimal portion, 0.32, into minutes. Since 1° is equivalent to 60 minutes, we multiply 0.32 by 60 to get the minute value.

The average increase in the number of flowers pollinated per day between days 4 and 10 is 39, given that the number of pollinated flowers as a function of time in days can be represented by the function \(f(x) = (3)^{\frac{x}{2} }\).

In the question, we are asked for the average increase in the number of flowers pollinated per day between days 4 and 10, given that the number of pollinated flowers as a function of time in days can be represented by the function \(f(x) = (3)^{\frac{x}{2} }\).

To find the average increase in the number of flowers pollinated per day between days 4 and 10, we use the formula {f(10) - f(4)}/{10 - 4}.

First, we find the value of the function \(f(x) = (3)^{\frac{x}{2} }\), for f(10) and f(4).

\(f(x) = (3)^{\frac{x}{2} }\\\Rightarrow f(10) = (3)^{\frac{10}{2} }\\\Rightarrow f(10) = 3^5 = 243\)

\(f(x) = (3)^{\frac{x}{2} }\\\Rightarrow f(4) = (3)^{\frac{4}{2} }\\\Rightarrow f(10) = 3^2 = 9\)

Thus, the average increase

= {f(10) - f(4)}/{10 - 4},

= (243 - 9)/(10 - 4),

= 234/6

= 39.

Thus, the average increase in the number of flowers pollinated per day between days 4 and 10 is 39, given that the number of pollinated flowers as a function of time in days can be represented by the function \(f(x) = (3)^{\frac{x}{2} }\).

Rounding to 0 decimal places, the Estimated Ultimate Recovery (EUR) for this reservoir is approximately 5,988 MMscf.

To calculate the Estimated Ultimate Recovery (EUR) for the reservoir, we can use the Arps equation, which relates the cumulative production (Q) to time (t) for a declining reservoir:

Q = (b / Di) * ((t + Di)^(-b) - Di^(-b))

Given the following data:

Initial production rate (agi): 165 MMscf/day

Decline rate (Di): 0.09/yr

Hyperbolic exponent (b): 0.51

We want to find the EUR, which is the cumulative production at infinite time (t = ∞).

At infinite time, the Arps equation simplifies to:

EUR = (b / Di) * (Di^(-b))

Substituting the given values into the equation:

EUR = (0.51 / 0.09) * (0.09^(-0.51))

EUR ≈ 5.67 * (1.056)

Answer: p = -3

Absolute value is a mathematical term used to describe the distance between a number and zero on a number line. It is written in algebraic form as |x|.

The absolute value of a number is always positive, even if the number itself is negative. For example, the absolute value of -5 is 5, and the absolute value of 5 is also 5.

When graphed on a number line, the absolute value of a number is the distance between that number and zero. Positive numbers are found on the right side of the number line, and negative numbers are found on the left side. The absolute value of a number is the same regardless of which side of the number line it is located.

Absolute value can be used to compare the distance between two numbers on a number line. For example, the absolute value of 6 minus the absolute value of 3 is equal to the absolute value of 3 minus the absolute value of 6. This is because the distance between the two numbers is the same regardless of the order of subtraction.

Absolute value can also be used to solve equations.

An "outcome" refers to a specific result or observation that can occur in a given situation or experiment. In the context of a population, an outcome represents one possible result that could be selected or observed.

When we talk about a population, we are referring to a group of individuals or items that share a common characteristic. For example, a population could be all the students in a school, all the trees in a forest, or all the cars in a city.

In statistics, we often take samples from populations to make inferences or draw conclusions about the entire population. When selecting a sample from a population, each individual or item in the population should have some probability of being chosen. This ensures that the sample is representative of the population and provides reliable information.

For example, if we want to study the average height of all students in a school, we might randomly select a sample of students from the population (all students in the school). Each student in the population has some chance of being selected, which means each student represents a potential outcome of the sample.

Answer:

Total time for which they ride = \(\bold{7\ hours}\)

Number of miles they ride each way = 24 mi

Step-by-step explanation:

Average speed = 8 mi/hr

Let the Distance to Mill Park = \(D\) mi

Let the time taken = \(t\) hours

Formula:

\(Distance = Speed \times Time\)

\(\Rightarrow D = 8t\) ..... (1)

Now, when average speed = 7 mi/hr

Time taken is 1 hour more, i.e. Time = \(t+1\) hours

Distance traveled is 4 mi more, i.e. \(D+4\) mi

Using the Formula:

\(Distance = Speed \times Time\)

\(D+4=7\times (t+1)\)

From equation (1):

\(8t+4=7t+7\\\Rightarrow t=3\ hours\)

From equation (1):

\(D = 8 \times 3 = 24\ mi\)

Total time for which they ride = \(t+t+1 = \bold{7\ hours}\)

Number of miles they ride each way = 24 mi
