The answer is 2.6825  cm, which is not one of the given options. Therefore, the correct answer is E. none of these.

The bulk modulus, B is defined as:

B = (P / ΔV / V), where P is the pressure applied, ΔV is the change in volume, and V is the original volume.

For a cube, the change in volume, ΔV is related to the change in length, ΔL by:

\(\sf \Delta V = \Delta L^3\).

Given that the cube has 2.0 cm sides, the original volume, V is:

\(\sf V = (2.0 \ cm)^3 = 8.0 \ cm^3\).

The pressure applied is \(\sf P = 2.0 \times 10^5\) Pa and the bulk modulus is \(\sf B = 4.7 \times 10^5 \ N/m^2\).

We can rearrange the bulk modulus formula to solve for ΔL as:

\(\sf \Delta L = \huge \text(\dfrac{P}{B} \huge \text) \times \dfrac{V}{3}\).

Substituting the values, we get:

\(\sf \Delta L = (2.0 \times 10^5 \ \dfrac{Pa}{4.7} \times 10^5\ N/m^2) \times \dfrac{8.0 \ cm^3}{3} = 0.6825 \ cm\)

Therefore, the final length of any side of the cube is:

\(\sf L = 2.0 \ cm + \Delta L = 2.0 \ cm + 0.6825 \ cm = 2.6825 \ cm\)

Therefore, the total distance Gabe will paddle is 2x + 400 meters. The exact value of x depends on the width of the river, which is not provided in the given information.

To find the total distance Gabe will paddle, we need to consider the distance he will travel from Q to P, then from P to R, and finally from R back to Q.

First, let's consider the distance from Q to P. Since Gabe will paddle in a diagonal line across the river, this distance can be calculated using the Pythagorean theorem.

The length of the bridge (PR) is given as 400 meters, which is the hypotenuse of a right triangle. The width of the river can be considered as the perpendicular side, and the distance Gabe will paddle from Q to P is the other side. Let's call this distance x.

Using the Pythagorean theorem, we have:

x^2 + (width of the river)^2 = PR^2

Since the width of the river is not given, we'll represent it as w. Therefore:

x^2 + w^2 = 400^2

Next, let's consider the distance from P to R. Gabe will paddle along a route beside the bridge, which means he will travel the length of the bridge (PR) again. So, the distance from P to R is also 400 meters.

Finally, Gabe will paddle back from R to Q along the shore. Since he will follow the shoreline, the distance he will paddle is equal to the distance from Q to P, which is x.

To find the total distance, we add up the distances:

Total distance = QP + PR + RQ

= x + 400 + x

= 2x + 400

When the circumference is 2 cm, the radius is changing at a rate of 3 cm/s.

To solve this problem, we can use the formula for the area of a circle: A = πr², where A is the area and r is the radius.

We are given that the area of the circle is increasing at a rate of 6 cm²/s. This means that dA/dt = 6.

We are asked to find how fast the radius is changing (rate of change) when the circumference is 2 cm. We know that the formula for the circumference of a circle is C = 2πr, where C is the circumference and r is the radius. So if the circumference is 2 cm, we can set up the equation:
2πr = 2

Solving for r, we get:
r = 1/π

Now we can differentiate the equation for the area with respect to time (t):
A = πr²
dA/dt = 2πr(dr/dt)

Substituting the values we know:
6 = 2π(1/π)(dr/dt)
6 = 2(dr/dt)
dr/dt = 3 cm/s

Therefore, when the circumference is 2 cm, the radius is changing at a rate of 3 cm/s.

The function T(n) in terms of the number of operations is:

T(n) = 2n^3 + 3n^2 + 2n + 1 and the asymptotic complexity of the matrix multiplication algorithm is O(n^3).

To analyze the provided pseudo code for matrix multiplication and determine the function T(n) in terms of the number of operations, we need to examine the code and count the number of operations performed.

The pseudo code for matrix multiplication may look something like this:

```

MatrixMultiplication(A, B):

   n = size of matrix A

   C = empty matrix of size n x n

   for i = 1 to n do:

       for j = 1 to n do:

           sum = 0

           for k = 1 to n do:

               sum = sum + A[i][k] * B[k][j]

           C[i][j] = sum

   return C

```

Let's break down the number of operations step by step:

1. Assigning the size of matrix A to variable n: 1 operation

2. Initializing an empty matrix C of size n x n: n^2 operations (for creating n x n elements)

3. Outer loop: for i = 1 to n

- Incrementing i: n operations  

- Inner loop: for j = 1 to n

- Incrementing j: n^2 operations (since it is nested inside the outer loop)

- Initializing sum to 0: n^2 operations

- Innermost loop: for k = 1 to n

- Incrementing k: n^3 operations (since it is nested inside both the outer and inner loops)

- Performing the multiplication and addition: n^3 operations

- Assigning the result to C[i][j]: n^2 operations

- Assigning the value of sum to C[i][j]: n^2 operations

Total operations:

1 + n^2 + n + n^2 + n^3 + n^3 + n^2 + n^2 = 2n^3 + 3n^2 + 2n + 1

Therefore, the function T(n) in terms of the number of operations is:

T(n) = 2n^3 + 3n^2 + 2n + 1

To determine the asymptotic (big O) complexity of the algorithm, we focus on the dominant term as n approaches infinity.

In this case, the dominant term is 2n^3. Hence, the asymptotic complexity of the matrix multiplication algorithm is O(n^3).

The total amount owed after 3 years with the given rate of interest compounded quarterly will be $2851.52.

Compound interest is applicable when there will be a change in principal amount after the given time period.

For example, if you give anyone $500 at the rate of 10% annually then $500 is your principle amount. After 1 year the interest will be $50 and hence principle amount will become $550 now for the next year the interest will be $550, not $500.

Given that,

Principle amount P = $2000

Rate of interest R = 12%

Compounded quarterly n = 4

Time period T = 3 years

Total amount = P{1 + R/n]^(nT)

Total amount = 2000[1 + 0.12/4]^(4×3)

Total amount = $2851.52

Given that Tara and Pablo leave the park at the same time, but in opposite directions. If Pablo travels 9 mph faster than Tara and after 5 hours they are 105 miles apart, we have to find how fast each is traveling.

Let Tara's speed be x mph, and then Pablo's speed is (x + 9) mph. The distance between the two speeds after 5 hours is equal to 105 miles, and we are to find how fast each is traveling. Using the distance formula:
distance = rate × time
Distance traveled by Tara + Distance traveled by Pablo = Total distance
They are travelling in opposite directions so we need to add the speed of Tara and Pablo, which is (x + x + 9) mph, to get the total distance travelled. The distance traveled by Tara = rate × time = x × 5 = 5x miles.
The distance traveled by Pablo = (x + 9) × 5 = 5x + 45 miles
Total distance traveled = Distance traveled by Tara + Distance traveled by Pablo105 = 5x + 5x + 45

The population of bacteria after 8 days is 7088

Here, we have been given an equation for the rate of growth of a population of bacteria

dP/dt = k√t

where P is the population size

and t is the time in days (0 ≤ t ≤ 10)

We rewrite above equation as,

dP = k√t dt

Integrating both sides, we get,

P = (2/3) × kt^(3/2) + C

We find the value of C.

For t = 0, P = 300 as the initial size of the population is 300.

Substitute t = 0 in above equation.

300 = 0 + C

C = 300

So, the above equation becomes,

P = 300 + (2/3) × kt^(3/2)                .......(1)

Now we find the value of k.

After 1 day the population has grown to 600.

substitute t = 1, P = 600 in equation (1)

600 = 300 + (2/3) × k

(2/3)k = 300

k = 900/2

k = 450

So, the equation of population of bacteria after time t is:

P = 300 + [(2/3) × 450 × t^(3/2)]

P = 300 + 300 × t^(3/2)

P = 300 (1 + t^(3/2))

To find the population after 8 days, substitute t = 8

P = 300 (1 + 8^(3/2))

P = 7088.22

William drove for 5 hours at an average speed of 54 mi/h.

For the first two hours, he drove at a speed of 45 mi/h.

William's average speed for the last three hours.

Let \(x\) represent the average speed for the last three hours (in mi/h).

The total distance traveled in the first two hours is \(\sf\:45 \, \text{mi/h} \times 2 \, \text{h} = 90 \, \text{miles} \\\).

The total distance traveled in 5 hours is \(\sf\:54 \, \text{mi/h} \times 5 \, \text{h} = 270 \, \text{miles} \\\).

The distance traveled in the last three hours is \(\sf\:270 \, \text{miles} - 90 \, \text{miles} = 180 \, \text{miles} \\\).

The average speed for the last three hours can be calculated as:

\(\sf\:\frac{\text{distance}}{\text{time}} = \frac{180 \, \text{mi}}{3 \, \text{h}} \\\)

Simplifying the expression:

\(\sf\:\frac{180}{3} = 60 \, \text{mi/h} \\\)

Therefore, the average speed for the last three hours is \(\sf\:\boxed{60 \, \text{mi/h}} \\\).

Answer:

Therefore, William's average speed for the last three hours was 60 mi/h, so the answer is (C) 60 mi/h.

Step-by-step explanation:

We can start by using the formula:

average speed = total distance / total time

We know that William drove for a total of 5 hours at an average speed of 54 mi/h, so the total distance he covered was:

total distance = average speed x total time

total distance = 54 mi/h x 5 h

total distance = 270 miles

We also know that for the first two hours, his speed was 45 mi/h. Therefore, he covered a distance of:

distance for first 2 hours = speed x time

distance for first 2 hours = 45 mi/h x 2 h

distance for first 2 hours = 90 miles

To find out the distance he covered for the last three hours, we can subtract the distance he covered in the first two hours from the total distance:

distance for last 3 hours = total distance - distance for first 2 hours

distance for last 3 hours = 270 miles - 90 miles

distance for last 3 hours = 180 miles

Finally, we can use the formula again to find his average speed for the last three hours:

average speed = distance for last 3 hours / time for last 3 hours

average speed = 180 miles / 3 hours

average speed = 60 mi/h

Answer:

y = \(\frac{1}{3}\) x - 6

Step-by-step explanation:

9y - 3x = -54

We want in the form

y = mx + b

9y - 3x = -54  Add 3x to both sides

9y - 3x + 3x =  3x - 54

9y = 3x - 54   Divide all the way through by 9

\(\frac{9y}{9}\) = \(\frac{3x}{9}\) - \(\frac{54}{9}\)

y = \(\frac{3}{9}\) x - 6

We can simplify \(\frac{3}{9}\) ÷ \(\frac{3}{3}\) = \(\frac{1}{3}\)

y = \(\frac{1}{3}\) x - 6

The probability that the two smartest people will be in the same group is approximately 0.023 or 2.3%.

The probability of the two smartest people being in the same group can be calculated by considering the total number of possible ways the groups can be formed and the number of ways the two smartest people can be in the same group.

To find the total number of ways the groups can be formed, we can use the concept of combinations. In this case, we have 36 people in the class and we want to split them into 12 groups of 3. We can calculate the total number of ways the groups can be formed using the formula for combinations:

C(n, r) = n! / (r! * (n-r)!)

where n is the total number of people and r is the number of people in each group.

In our case, n = 36 and r = 3. Plugging these values into the formula, we get:

C(36, 3) = 36! / (3! * (36-3)!)

Simplifying this expression, we find that there are 7140 different ways to form the groups.

Now, let's calculate the number of ways the two smartest people can be in the same group. Since there are 12 groups and we want the two smartest people to be in the same group, we can treat them as a single unit. So, we need to calculate the number of ways to distribute the remaining 34 people into 11 groups of 3.

Using the same combination formula, we have:

C(34, 3) * C(11, 1) = (34! / (3! * (34-3)!) * (11! / (1! * (11-1)!))

Simplifying this expression, we find that there are 163,800 different ways to distribute the remaining people.

Now, to calculate the probability, we divide the number of ways the two smartest people can be in the same group by the total number of possible ways the groups can be formed:

Probability = (Number of ways the two smartest people in the same group) / (Total number of possible ways to form groups)

Probability = 163,800 / 7,140

Simplifying this expression, we find that the probability is approximately 0.023 or 2.3%.

Therefore, the probability that the two smartest people will be in the same group is approximately 0.023 or 2.3%.
