The temperature in salt lake city will be 0° Celsius.

Temperature tells us about the degree of hotness or coldness of a body. According to the thermodynamics, temperature is a measure of the average kinetic energy of the atoms or molecules in the system.

Given is Salt Lake City where it is 8˚ colder than it is in Houston.

The degree of coldness on Celsius scale increase as the temperature tends to negative values and degree of hotness on Celsius scale increase as the temperature tends to positive values. The temperature in Houston is 8° Celsius. Since, the temperature is 8 degrees colder, we will subtract 8° from the temperature value in Houston. Therefore, temperature in salt lake city will be -

T[S] = + 8 - 8 = 0° Celsius

Therefore,  the temperature in salt lake city will be 0° Celsius.

we can infer that the firm is currently maximizing its profit. Option (b), "the firm is currently maximizing its profit," is the most appropriate inference from the provided data.

To determine whether the firm is maximizing its profit, we need to analyze the relationship between marginal revenue (MR), marginal cost (MC), and price. In a monopolistically competitive market, firms aim to maximize their profit by producing at a level of output where MR equals MC.

From the information provided, we know that the firm's marginal revenue is equal to $15 and marginal cost is also equal to $15. This indicates that the firm is producing at the level where its marginal revenue equals its marginal cost, which is a characteristic of profit maximization.

Additionally, we are told that the firm is charging the highest price it can at $30. This means that the firm is able to set its price above its average total cost, resulting in a positive difference between price and average total cost, known as economic profit.

Step-by-step explanation:

Answer:

x = -47

Step-by-step explanation:

Hi there!
We are given the equation x + 18 = -29 and we want to solve it for x

To solve these kinds of equations, we want to isolate x on one side of the equation (one side of the equation should ONLY have x on it).
In order to isolate x, we can add, multiply, subtract, or divide the equation by any numbers we choose

In this case, we'll need to get rid of 18 from the left side, so let's subtract 18 from both sides to remove it from the equation

So let's get on with subtracting 18 from both sides:
x + 18 = -29

Subtract 18 from BOTH sides

x+ 18 = -29
-18      -18
_______________

x=-29-18
Subtract 18 from -29

x = -47, which is our solution

Answer:

Triple

Step-by-step explanation:

V = π * r^2 *h

h is directly proportional to V so when h increases V increases.

This is a linear relationship so if h is tripled the volume will be tripled as well.

if r tripled then V would be 9 times as large since r has a square relationship with V.

If you're unsure about these just plug in number r= 2, h= 4, and perform the operation they ask you to do (triple or double) and you'll always get it right.

To calculate the surface integral of the vector field F = xi + yj + zk over the portion S of the surface y = x² + 2², where y ≤ 4 and the orientation is in the positive y-direction, we need to compute the dot product F · dS. This can be achieved by parameterizing the surface S and evaluating the dot product over the parameterized surface.



First, we need to parameterize the surface S. Given the equation y = x² + 2², we can express it as a vector function r(x, y) = xi + (x² + 2²)j + zk, where x ranges from -∞ to +∞ and y ranges from -∞ to 4.

Next, we need to calculate the normal vector dS for the surface S. The normal vector is given by the cross product of the partial derivatives of r with respect to x and y. Taking the partial derivatives, we have ∂r/∂x = i + 2xj and ∂r/∂y = j. The cross product of these vectors gives us the normal vector dS = (∂r/∂x) × (∂r/∂y) = (2xk) - 2j + ik.

Now, we can compute the dot product F · dS. Substituting the components of F and dS, we have F · dS = (x(2x) - 2y + z)(2x) - 2j + ik = (2x³ - 2y + z)(2x) - 2.

To calculate the surface integral, we integrate F · dS over the parameterized surface S. However, since the surface is unbounded in the x-direction, we need to evaluate the integral over a specific range of x. In this case, since y ≤ 4, we can set the range of x as -∞ to +∞.

Therefore, the surface integral F · dS can be computed as ∫∫(2x³ - 2(x² + 2²) + z)(2x) - 2 dA, where dA represents the differential area element in the xy-plane.

By evaluating this double integral over the given range, the surface integral of the vector field F over the surface S can be determined.

The dimension of the max garden is 125*125 and the max area is 15625 square feet.

Let the length and width of the garden be L and B.

Now, let the barn is along the width. So, now the width became = B-50

So the perimeter = 2(L+B-50)

Now to fence the garden we need 400 feet material.

So, 2(L+B-50) = 400

L+B-50 = 200

B = 250-L .........(i)

So the area of the total garden is given by,

A = LB = L(250-L) \(=250L-L^2\)

So now differentiating the area with respect to length,

dA/dL = 250-2L

\(\frac{d^2A}{dL^2}=\) -2

Now, dA/dL = 0 gives,

250-2L = 0

2L = 250

L= 125

At L = 125, \(\frac{d^2A}{dL^2}=-2 < 0\)

Max A = \(250\times125-125^2=15625\) square feet

So area is maximum when L = 125 feet.

Then the width = B = 250-125 = 125 feet.

Hence the dimension of the max garden is 125*125 and the max area is 15625 square feet.

The number of ways to roll a total of 24 with four 10-sided dice is 2925.

To solve this problem using inclusion-exclusion, we need to consider all possible ways to roll a total of 24 with the four 10-sided dice, and then subtract the number of cases where at least one die rolls a number greater than 10.

However, we also need to add back the number of cases where at least two dice roll a number greater than 10, since they were subtracted twice.

Let A be the event that at least one die rolls a number greater than 10, and let B be the event that at least two dice roll a number greater than 10. Then we can use the inclusion-exclusion principle:

N(A) = total number of ways to roll 24 with four 10-sided dice = (number of solutions to x1 + x2 + x3 + x4 = 24) = C(24 + 4 - 1, 4 - 1) = C(27, 3) = 2925

N(B) = total number of ways to roll 24 with at least two dice greater than 10

If two dice are greater than 10, then their sum can be 11, 12, ..., 18, for a total of 8 possibilities. For each of these cases, we need to find the number of ways to distribute the remaining 16 points among the four dice, where each die can have any value from 1 to 10. This can be done using stars and bars:

For 11, the remaining 16 points can be distributed among 4 dice in C(16 + 4 - 1, 4 - 1) = C(19, 3) = 969 ways.

For 12, the remaining 16 points can be distributed among 4 dice in C(14 + 4 - 1, 4 - 1) = C(17, 3) = 680 ways.

For 13, the remaining 16 points can be distributed among 4 dice in C(12 + 4 - 1, 4 - 1) = C(15, 3) = 455 ways.

For 14, the remaining 16 points can be distributed among 4 dice in C(10 + 4 - 1, 4 - 1) = C(13, 3) = 286 ways.

For 15, the remaining 16 points can be distributed among 4 dice in C(8 + 4 - 1, 4 - 1) = C(11, 3) = 165 ways.

For 16, the remaining 16 points can be distributed among 4 dice in C(6 + 4 - 1, 4 - 1) = C(9, 3) = 84 ways.

For 17, the remaining 16 points can be distributed among 4 dice in C(4 + 4 - 1, 4 - 1) = C(7, 3) = 35 ways.

For 18, the remaining 16 points can be distributed among 4 dice in C(2 + 4 - 1, 4 - 1) = C(5, 3) = 10 ways.

So, the total number of ways to roll 24 with at least two dice greater than 10 is:

N(B) = 8*(969 + 680 + 455 + 286 + 165 + 84 + 35 + 10) = 38304

By the inclusion-exclusion principle, the number of ways to roll a total of 24 with four 10-sided dice is:

N = N(A) - N(B)

Speed in still water: 8 km/h

Speed of river: 2 km/h

Speed downstream: 8 km/h + 2 km/y = 10 km/h

Speed upstream: 8 km/h - 2 km/h = 6 km/h

total time both ways: 48 minutes = 48/60 hour = 0.8 hour

time to go upstream: t

time to go downstream: 0.8 - t
