Matter is in a liquid state when its temperature is between its melting point and its boiling point. Suppose that some substance has a melting point of -36.14 degrees Celsius and a boiling point of 324.84 degrees Celsius . What is the range of temperatures in degrees Fahrenheit for which this substance is not in a liquid​ state?

Evaluating the expression, we find that f′′(2) = -76 + 8 = -68.

To find f′(0), we can use the product rule for differentiation. The product rule states that if we have a function f(x) = g(x)h(x), then the derivative of f(x) is given by f′(x) = g′(x)h(x) + g(x)h′(x).

In this case, we have f(x) = e^xg(x), so using the product rule, we can differentiate f(x) with respect to x:

f′(x) = e^xg′(x) + e^xg(x)h′(x)

Given that g(0) = 1 and g′(0) = 2, we can evaluate f′(0) by substituting these values into the expression:

f′(0) = e^0 * 2 + e^0 * 1 * h′(0)

= 2 + h′(0)

Since h′(0) is not specified, we cannot determine its exact value. However, we can conclude that f′(0) = 2.

Next, we are given that f′(x) = x^2f(x) for all x. To find f′′(2), we need to differentiate f′(x) with respect to x and evaluate it at x = 2.

Differentiating f′(x) = x^2f(x) using the product rule, we get:

f′′(x) = (2x)f(x) + x^2f′(x)

Substituting x = 2, we have:

f′′(2) = (2*2)f(2) + 2^2f′(2)

= 4f(2) + 4f′(2)

= 4(-19) + 4(2)

Evaluating the expression, we find that f′′(2) = -76 + 8 = -68.

Step-by-step explanation:

Top left: X is greater than or equal to 3. Top right: X is less than or equal to 3. Bottom left: X is greater than 3. Bottom right: X is less than 3.

The greater than or equal to sign and the less than or equal to sign has a closed circle because it is marking the point and moving forward or back. Ex: less than or equal to 3. It would be a closed circle because it is the specific point and what ever is beyond or behind it. The less than or greater than sign would have a closed circle because it is only what is beyond or behind the certain number.

The immigration agent is 100% busy on average.

Based on the information provided, we can calculate the arrival rate of entrants as follows:

Arrival rate = 1/6 minutes per entrant = 0.1667 entrants per minute

Next, we can calculate the processing rate of the immigration agent as follows:

Processing rate = 120 entrants per 8 hour shift = 0.05 entrants per minute

Using Little's Law, we can calculate the average number of entrants in the system as follows:

Average number of entrants = Arrival rate x Average time in the system

where Average time in the system = 1/Processing rate

Plugging in the values, we get:

Average number of entrants = 0.1667 x (1/0.05) = 3.333

Therefore, the immigration agent is busy with an average of 3.333 entrants in the system. To determine how busy she is as a percentage, we can use the following formula:

% utilization = (Average number of entrants / Number of servers) x 100%

In this case, there is only one immigration agent, so the number of servers is 1. Plugging in the values, we get:

% utilization = (3.333 / 1) x 100% = 333.3%

Since the maximum utilization cannot exceed 100%, the answer is 100%. Therefore, the immigration agent is 100% busy on average.

a. From fastest to slowest, the speeds of the balls at the right ends of the tracks will depend on the curvature of the tracks.

If the tracks are of equal length but have different curvatures, the ball on the track with the least curvature will have the highest speed, followed by the ball on the track with the next least curvature, followed by the ball on the track with the most curvature.

b. From longest to shortest, the tracks in terms of the times for the balls to reach the ends will depend on the curvature of the tracks. If the tracks are of equal length but have different curvatures, the track with the most curvature will have the longest time for the ball to reach the end, followed by the track with the next most curvature, followed by the track with the least curvature.

c. From greatest to least, the tracks in terms of the average speeds of the balls will depend on the curvature of the tracks. If the tracks are of equal length but have different curvatures, the track with the least curvature will have the highest average speed, followed by the track with the next least curvature, followed by the track with the most curvature.

All the balls will have the same average speed on all three tracks if the track lengths are equal, but will have different speeds at the end of each track due to the different curvatures.

Temperature is a variable that uses (2) the scale interval and, according to physical theory, represents in the numerical form how hot or cold something is.

The physical concept of temperature indicates in numerical form how hot or cold something is.

A thermometer is used to determine temperature.

One variable that makes use of the scale interval is temperature.

Thermometers are calibrated using a variety of temperature scales, which historically defined distinct reference points and thermometric substances.

The most popular scales are the Celsius scale, sometimes known as centigrade, with the unit symbol °C, the Fahrenheit scale (°F), and the Kelvin scale (K), with the latter being mostly used for scientific purposes.

One of the seven base units in the International System of Units is the kelvin (SI). The lowest point on the thermodynamic temperature scale is absolute zero, or zero Kelvin, or 273.15 °C.

The condition for the equation (∂U/∂V)T = (∂U/∂P)T = (∂H/∂V)T = 0 to be true is that the system described must be in a state of mechanical, thermal, and chemical equilibrium.

Let's break down the conditions for each partial derivative:

1. (∂U/∂V)T = 0: This condition implies that the internal energy of the system does not change with respect to volume at constant temperature.

It indicates mechanical equilibrium, where the system is in balance and no work is being done on or by the system due to volume changes.

2. (∂U/∂P)T = 0: This condition suggests that the internal energy of the system does not change with respect to pressure at constant temperature.

It indicates thermal equilibrium, where the system is in balance and there is no transfer of energy as heat due to pressure changes.

3. (∂H/∂V)T = 0: This condition implies that the enthalpy of the system does not change with respect to volume at constant temperature.

It also indicates mechanical equilibrium, where the system is in balance and there is no work being done on or by the system due to volume changes.

In summary, the condition (∂U/∂V)T = (∂U/∂P)T = (∂H/∂V)T = 0 is true when the system is in a state of mechanical, thermal, and chemical equilibrium, where there are no changes in internal energy, pressure, and enthalpy with respect to volume at constant temperature.

Answer:

x = 9

Step-by-step explanation:

first step, multiply both sides by 6. This is going to get rid of that fraction-looking situation on the left.

3x+9 / 6 = x - 3

6• 3x+9 /6 = 6(x-3)

On the left the 6s cancel (cancel is not a technical math term, but 6/6 is 1, so you are left with only the 3x+9)

3x + 9 = 6(x - 3)

Next, use distributive property on the right side.

3x + 9 = 6x - 18

Subtract 3x from both sides.

9 = 3x - 18

Add 18 to both sides.

27 = 3x

Divide both sides by 3.

27/3 = x

9 = x

The answer is 50 grams of salt in the tank at all times.

To find the number of grams of salt in the tank at time t, we need to use the formula:

a(t) = a(0) + (r - p) * t

where a(0) is the initial amount of salt in the tank, r is the rate at which brine is being pumped into the tank, p is the rate at which the solution is being pumped out of the tank, and t is the time elapsed.

In this case, a(0) = 50 grams, r = 3 grams per minute (since the brine contains 1 gram of salt per liter and 3 liters are being pumped in per minute, so 3 grams of salt are being added per minute), and p = 3 grams per minute (since the solution is being pumped out at the same rate as it is being pumped in). Therefore, we can simplify the formula to:

a(t) = 50 + 0 * t
a(t) = 50 grams

This means that the amount of salt in the tank remains constant over time, since the rate at which it is being pumped in and out is equal. Therefore, the answer is 50 grams of salt in the tank at all times.

The principal stresses are those that act on the principal planes. There are three principal stresses on a point under force.  

The principal stresses are those that act on the principal planes. The plane bearing the greatest normal stress is referred to as the principal plane, and the stress acting on it is referred to as the principal stress.

When a force is applied on an inclined plane, the force can be divided into two subparts, the first component of the force is perpendicular to the plane and is known as the normal force, while the second component of the force is parallel to the plane and is known as the shear stress.

The principal stresses at a point can be found using the following formulas, therefore, the principal stresses will be,

\({\sigma}'_{xx}=\sigma_{xx}cos(2\theta)+\sigma_{yy}sin(2\theta)+2\tau_{xy}sin(\theta)cos(\theta)\)

\({\sigma}'_{yy}=\sigma_{xx}sin(2\theta)+\sigma_{yy}cos(2\theta)-2\tau_{xy}sin(\theta)cos(\theta)\)

\({\tau}'_{xy}=(\sigma_{yy}-\sigma_{xx})sin\theta cos\theta+\tau_{xy}(cos2\theta-sin2\theta)\)

A null hypothesis outlines what a researcher should see if the tested hypothesis is incorrect. In essence, it presents an "alternative" theory to the first.

The null hypothesis is a type of hypothesis that explains the population parameter and is used to examine if the provided experimental data are reliable. Depending on whether the population or sample under consideration is viable, this hypothesis is either rejected or not. Or to put it another way, the null hypothesis is a hypothesis that assumes that the sample observations are the result of chance. It is claimed to be a claim made by surveyors who wish to look at the data.

The original price of milk is Rs. 14.

Let the original price of milk be Rs. x and the original quantity of milk purchased be y liters. After the rise, the new price of milk becomes 14.28% + 100% of the original price of milk i.e. (100% + 14.28%) = 114.28% of the original price of milk. Therefore, the new price of milk becomes (114.28/100)*x = 1.1428x. Now, due to the 14.28% rise in price, the milkman is able to purchase 20 liters less of milk for Rs. 5600. Using this information, let's set up an equation as follows:(x/y) - (1.1428x)/(y - 20) = 5600/y where the left-hand side of the equation represents the original cost of the milk minus the new cost of the milk after the price rise. The above equation can be simplified as follows:(x/y) - (1.1428x)/(y - 20) = (5600/y) * (y/(5600 + 20x)).After simplification, the equation becomes :x(y - 20) = (5600 + 20x)*y. Now,  substitute the values given in the question to get the original price of milk as follows: x(y - 20) = (5600 + 20x)*y x(y - 20) = 5600y + 20xy - 400xy = 5600yx - 20xy - 5600y = -400xy = (5600y)/(x - 20y) = 5600/400 = 14.
