Given that the cost is $1.10 per pound, we can calculate the cost per servable pound by dividing the total cost ($1.10 * 4 pounds) by the servable weight (2 pounds). Therefore, the correct option is c. $2.20.

The original weight of the food item is 4 pounds, and the cost per pound is $1.10. Therefore, the total cost of the food item is 4 pounds * $1.10 = $4.40.

The servable weight of the food item is 2 pounds. To find the cost per servable pound, we divide the total cost ($4.40) by the servable weight (2 pounds):

Cost per servable pound = Total cost / Servable weight = $4.40 / 2 pounds = $2.20.

Hence, the cost per servable pound for this food item is $2.20. Therefore, the correct option is c. $2.20.

Step-by-step explanation:

Remember that i² = -1

The value of f[g(x)] is - 64x³ - 336x² - 588x - 340 and the value of g[f(x)] is -4x³ + 19

The functions are as follows; f(x) = -x³ +3 and g(x) = 4x+7

The value of f[g(x)] is obtained by replacing every x in f(x) with the value of g(x) as given below

f[g(x)] = f(4x + 7) = - (4x + 7)³ + 3

When we expand (4x + 7)³, it gives us 64x³ + 336x² + 588x + 343

Then

f[g(x)] = - 64x³ - 336x² - 588x - 340

Similarly, g[f(x)] is obtained by replacing every x in g(x) with the value of f(x) as shown below;

g[f(x)] = g(-x³ + 3) = 4(-x³ + 3) + 7g

[f(x)] = -4x³ + 19

Therefore,

f[g(x)] = - 64x³ - 336x² - 588x - 340

g[f(x)] = -4x³ + 19

A disk with a radius of 0.1 m is spinning about its center with a constant angular speed of 10 rad/sec. The speed of the bug is equal to the tangential speed of a point on the rim of the disk, which can be given by: v = rωWhere:r = 0.1 m (the radius of the disk)ω = 10 rad/sec (the angular speed of the disk)Therefore, the speed of the bug is: v = rω= 0.1 m x 10 rad/sec= 1 m/s

The acceleration of the bug can be given by: a = rαWhere:α = α (angular acceleration)The angular acceleration is zero because the disk is spinning at a constant angular speed. Hence, the acceleration of the bug is zero or a = 0 m/s². Therefore, the correct option is option 2) 1 m/s and 0 m/s² (Disk spins at a constant speed).

The length of s = 1/3

Answer:

x = 16 feet

Step-by-step explanation:

I'm guessing the shape given is a rectangle? Anyways, to find the area we multiply the sides, this gives us the equation:

(x - 12)(x - 5) = 44

We can distribute to get

x^2 - 12x - 5x + 60 = 44

x^2 - 17x + 60 = 44

Now, to get the equation equal to zero, we can subtract 44 from both sides:

x^2 - 17x + 16 = 0

To factor this, we are looking for two numbers that multiply to 16 and add up to -17. These two numbers are -1 & -16, therefore, the factored form is:

(x - 1)(x - 16) = 0

We can use the zero product property to say x = 1 and x = 16. We can cross out the solution x = 1, because when plugged in, we get side lengths less than one. So the sole answer is x = 16.

Step-by-step explanation:

Enthalpy change (∆H) of the given reaction is -300 kJ/mol.

Let's discuss it further below.

In the given equation, 2 Xm3(g) reacts to produce 2 Xm2(g) and M2(g). The symbol "X" represents the element and "M" represents an inert gas like helium or neon.

The question is asking about the enthalpy change (∆H) of the given chemical reaction. The enthalpy change (∆H) is the amount of energy released or absorbed during a chemical reaction.

It can be calculated using the difference in the energy of the reactants and the products. If the enthalpy change is negative, the reaction is exothermic, and if the enthalpy change is positive, the reaction is endothermic. If the enthalpy change is zero, the reaction is said to be in equilibrium.

To determine the enthalpy change of the given reaction, we need to know the enthalpy of the reactants and the products. The enthalpy of a substance is its heat content at constant pressure.

The standard enthalpy of formation (∆H°f) is the enthalpy change when one mole of a compound is formed from its constituent elements in their standard states (∆H°f of the elements is zero).

The standard enthalpy of formation (∆H°f) of the reactants and products are given below:

∆H°f (Xm3(g)) = -300 kJ/mol∆H°f (Xm2(g)) = -450 kJ/mol∆H°f (M2(g)) = 0 kJ/mol

Now we can calculate the enthalpy change (∆H) of the given reaction using the formula:

∆H = Σ∆H°f (products) - Σ∆H°f (reactants)

where Σ represents the sum of the values.

∆H = [2(-450 kJ/mol) + 0 kJ/mol] - [2(-300 kJ/mol)]∆H = -900 kJ/mol + 600 kJ/mol∆H = -300 kJ/mol

Therefore, the enthalpy change (∆H) of the given reaction is -300 kJ/mol. This means that the reaction is exothermic, and energy is released during the reaction.

The 95% confidence interval for the mean exchange rate between the U.S. Dollar and Euros is $0.771/Euro to $1.2287/Euro.

To solve this question, we use the concept of calculating the confidence interval for a population mean.

The confidence interval is a range of values, in which we are sure that the population parameter lies truly. With this, we can estimate the uncertainty associated with estimating population parameters, based on the given data.

The formula used to find the confidence interval is as follows:

Confidence Interval (C.I) = Sample Mean ± (Critical Value) * (Standard Error)

Before we arrive at the interval, we need the values of a few terms, such as the Standard error and the Critical value.

Standard Error:

It is a representation of the standard deviation of the sample mean. It is the ratio of the standard deviation to the root of the size of the sample size.

So,

Standard error = √Population Variance/√Sample size in months

(Population deviation is the square root of Variance)

Error =  √0.49 / √36

        = 0.7/√36

        = 0.7/6

        = 0.116

Thus, the standard error is 0.116.

Critical Value:

We need the critical value associated with the 95% confidence level, for which we use the Z-distribution to find the value. We can use a Z-table or calculator.

For 95%, the critical value is approximately 1.96.

Now, we substitute the information in the original equation.

Confidence Interval = $1 ± (1.96)*(0.1167)

C.I = 1 ± 0.2287

C.I = [$0.771, $1,2287]

Therefore, the 95% confidence interval for the mean U.S. dollar/Euro exchange rate is approximately $0.771/Euro to $1.2287/Euro.

The initial value problem \(yy' - y + ywth = 0\), with y(4) = 3, we can use the substitution u = y^2. Taking the derivative of u with respect to x, we have \(du/dx = 2yy\)'. Substituting this into the original equation, we get 2\(yy' - y + ywth = 0\), which simplifies to \(yy' + ywth/2 = y/2\).

Now we have a linear differential equation in y and x.

To solve this equation, we can use an integrating factor. The integrating factor is \(e^_(∫wth/2 dx)\), where wth/2 is a constant.

Multiplying the entire equation by this integrating factor, we obtain the following:

\(e^(∫wth/2 dx)yy' + e^(∫wth/2 dx)ywth/2 = (y/2)e^(∫wth/2 dx)\).

This can be rewritten as\(d/dx(e^(∫wth/2 dx)y) = (y/2)e^(∫wth/2 dx)\).

Integrating both sides with respect to x, we have

\(∫d/dx(e^(∫wth/2 dx)y) dx = ∫(y/2)e^(∫wth/2 dx) dx\).

Simplifying further, we get\(e^(∫wth/2 dx)y = ∫(y/2)e^(∫wth/2 dx) dx + C\).

Solving for y, we have \(y = e^(-∫wth/2 dx) * (∫(y/2)e^(∫wth/2 dx) dx + C)\).

In summary, by using the substitution \(u = y^2\), we transformed the original initial value problem into a linear differential equation in y and x. Using an integrating factor, we solved the linear equation and obtained the solution for y in terms of x and the constant C.

What is the probability?

 Probability is the ability to happen. The subject of this area of mathematics is the occurrence of random events. From 0 to 1 is used to express the value. To forecast how likely occurrences are to occur, Probability has been introduced in mathematics.

F= The probability that the dice land on different numbers.

F=(1,2),(1,3),(1,4),(1,5),(1,6),(2,1),(2,3),(2,4),(2,5),(2,6),(3,1),(3,2),(3,4),(3,5),(3,6),(4,1),(4,2),(4,3),(4,5),(4,6),(5,1),(5,2),(5,3),(5,4),(5,6),(6,1),(6,2),(6,3),(6,4),(6,5)

F = \(\frac{30}{36}= \frac{5}{6}\)

E= The event that at least one lands on 6.

E=(1,6),(2,6),(3,6),(4,6),(5,6),(6,1),(6,2),(6,3),(6,4),(6,5),(6,6)

E= \(\frac{11}{36}\)

What is the probability of E, when given that F has occurred?

P= \(\frac{P(EF)}{P(F)}\) = \(\frac{1-P(EF)}{P(F)}\)

=> P = \(\frac{\frac{11}{36} }{\frac{5}{6} }\) = \(\frac{11}{30}\)

To find the rate at which the area of the ice cap was changing in 2013, we can use the formula for the derivative of the area with respect to time.

Given:

Radius of the ice cap (r) = 792 mi

Rate of change of radius (dr/dt) = -4.1 mi/yr (negative because the radius is shrinking)

The formula for the area of a circle is A = πr²
