the length of each side of a cube is multiplied by a 3. what is the change in the surface area of the cube?

The overall gain or loss from Peter's moves is 12.

The correct option is C.

To find the overall gain or loss from Peter's moves, we need to consider the direction and magnitude of each move. A positive value represents a gain or moving forward, while a negative value represents a loss or moving backward.

In this case, Peter had a gain of 5 spaces, followed by a loss of 2 spaces, a gain of 12 spaces, a gain of 7 spaces, and finally a loss of 10 spaces. When we add up these individual gains and losses, we find that the total sum is 12.

This means that, overall, Peter gained a net total of 12 spaces from all his moves. It indicates that he moved forward more than he moved backward. The positive value suggests a net gain in terms of spaces on the game board.

Therefore, the answer C) 12 represents the overall gain or loss from Peter's moves.

Therefore, h(x, y) = 49x^3 - 294x^2y + 441xy^2 - 252x^2 + 252xy - 588y^2 + 294x - 252y - 1764.

To find h(x, y) = g(f(x, y)), we first need to evaluate f(x, y) and then use the result as input for g(t).
Starting with f(x, y), we have:
f(x, y) = 7x - 6y - 42
Next, we need to use this as input for g(t), which is defined as:
g(t) = t^2*t
Substituting f(x, y) for t, we get:
g(f(x, y)) = (7x - 6y - 42)^2*(7x - 6y - 42)
Simplifying this expression, we can expand the square and get:
h(x, y) = 49x^3 - 294x^2y + 441xy^2 - 252x^2 + 252xy - 588y^2 + 294x - 252y - 1764

Non-rivalry and non-excludability apply to public goods. Public goods are goods or services that are non-excludable,

meaning that it is impossible or impractical to exclude people from using them, and non-rivalrous, meaning that consumption of the good by one individual does not diminish its availability to others.

Examples of public goods include national defense, clean air and water, and scientific research. Because of their non-excludable and non-rivalrous nature, public goods often suffer from under-provision in a market economy.

Private goods, on the other hand, are both rivalrous and excludable. This means that only one person can consume the good at a time, and individuals can be prevented from consuming the good if they do not pay for it.

Goods produced by monopolies and natural resources can be either private or public goods depending on their excludability and rivalrousness.

The width of the rectangle is 2n^9 - 5n^3 + 28.

To find the width of the rectangle, we need to use the formula for the area of a rectangle:
Area = Length x Width

We are given that the area of the rectangle is:
12n^12 - 30n^6 + 168n^3

And we know that the length of the rectangle is:
6n³

So we can plug these values into the formula and solve for the width:

Area = Length x Width
12n^12 - 30n^6 + 168n^3 = 6n^3 x Width

Dividing both sides by 6n^3:
2n^9 - 5n^3 + 28 = Width

Therefore, the width of the rectangle is 2n^9 - 5n^3 + 28.

After 20 minutes, the temperature of the pan will be approximately 29°F.

Using Newton's Law of Cooling, we can write:

T(t) = To + (T₁ - To)e^(-kt)

where T(t) is the temperature of the pan at time t, To is the temperature of the freezer, T₁ is the initial temperature of the pan, and k is a constant that depends on the properties of the pan and the freezer.

We know that after 15 minutes, the temperature of the pan is 41°F, so we can write: 41 = 0 + (140 - 0)e^(-15k)

Simplifying this expression, we get:

e^(-15k) = 41/140

Taking the natural logarithm of both sides, we get:

-15k = ln(41/140)

Solving for k, we get:

k ≈ 0.056

this ratio relates to a right triangle, with hypotenuse h and

legs 3[tex]\sqrt{5}[/tex] and 2

using Pythagoras' identity in the right triangle

h² = (3[tex]\sqrt{5}[/tex] )² + 2² = 45 + 4 = 49 ( take square root of both sides )

After taking the Laplace transform, we obtain f(s) = (72/s^38) - (20/(s^2 + 25)) * (2/(s + 3)). The Laplace transform of the function f(t) = 2t^36 - 2sin(5t) * 2e^(-3t) can be found by applying the linearity and derivative properties of the Laplace transform.

To find the Laplace transform of f(t) = 2t^36 - 2sin(5t) * 2e^(-3t), we can apply the linearity property of the Laplace transform.

The Laplace transform of 2t^36 can be found using the derivative property of the Laplace transform. Taking the derivative of t^36, we get 36t^35. Then, applying the Laplace transform to 36t^35, we obtain (36!/s^37).

The Laplace transform of 2sin(5t) can be directly found using the standard Laplace transform table. The transform of sin(5t) is 5/(s^2 + 25).

The Laplace transform of 2e^(-3t) can also be found using the standard Laplace transform table. The transform of e^(-at) is 1/(s + a).

Now, using the linearity property of the Laplace transform, we can combine the transforms of each term:

f(s) = (72/s^37) - (20/(s^2 + 25)) * (2/(s + 3)).

Thus, the Laplace transform of f(t) is f(s) = (72/s^37) - (40/(s^2 + 25)(s + 3)).

Angles 4 and 8 do not equal 180 degrees (supplementary), therefore letter A is the answer.

Step-by-step explanation:

Looking at the other angles they all equal 180 degrees except for A which would appear to equal more than 180.

The total number of students in the sixth grade is equal to 250.

Percent of students purchased their lunch = 24%

Number of students brought their lunch from home = 190

Let us call the total number of students in the 6th grade 'x'.

We know that all students either purchased their lunch or brought their lunch from home,

x = students who purchased their lunch + students who brought their lunch from home

24% of the students purchased their lunch, so the number of students who purchased their lunch is 0.24x.

And we know that 190 students brought their lunch from home.

Substituting these values into the equation above, we get,

x = 0.24x + 190

Solving for x, we can start by subtracting 0.24x from both sides,

⇒ 0.76x = 190

Then we divide both sides by 0.76 to isolate x,

x = 250

Thus, the two possible values for angle A are 67.4° and 112.6° to the nearest tenth of a degree.

In △ABC, you have given B = 51°, b = 35, and a = 36. To find the two possible values for angle A, we can use the Law of Sines.

The Law of Sines states: (sinA)/a = (sinB)/b

Plugging in the given values, we get:
(sinA)/36 = (sin51°)/35

Now, solve for sinA:
sinA = 36 * (sin51°)/35 ≈ 0.923

Since sinA = 0.923, we can find the two possible values for angle A using the inverse sine function:

1. A = arcsin(0.923) ≈ 67.4°
2. A = 180° - arcsin(0.923) ≈ 112.6°

So, the two possible values for angle A are 67.4° and 112.6° to the nearest tenth of a degree.

The set of all points equidistant from points A(-1, 4, 2) and B(4, 1, -1) forms a plane perpendicular to AB.

To find the equation of this plane, we can use the midpoint formula to find the coordinates of the midpoint M between A and B, and then use the vector AB as the normal vector for the plane.

Midpoint M:

M = ((-1 + 4) / 2, (4 + 1) / 2, (2 - 1) / 2) = (1.5, 2.5, 0.5)

Vector AB:

AB = B - A = (4 - (-1), 1 - 4, -1 - 2) = (5, -3, -3)

Now, we can write the equation of the plane in point-normal form:

The chain rule states that if a function is composed of two functions, say f(x) and g(x), then its derivative can be computed as f′(g(x))g′(x). Using this rule and the given information, we can find f′(5) as follows.

First, we know that f(5) = f(g(5)) by definition. Since g(5) = −4, we can write this as f(5) = f(−4). Taking the derivative of both sides with respect to x, we get f′(5) = f′(−4)g′(5). We know f′(−4) = 3 and g′(5) = 4 from the given information, so we can substitute these values into the equation to obtain f′(5) = 3(4) = 12. Therefore, the derivative of the function f(x) at x = 5, denoted by f′(5), is equal to 12. This means that the slope of the tangent line to the graph of f(x) at x = 5 is 12.

The probability of the price of milk being between $2.8 and $3.0 is 0.1359 or 13.59% (rounded to two decimal places).

To solve this problem, we need to standardize the values using z-scores, which is calculated as (x - μ) / σ where x is the value, μ is the mean, and σ is the standard deviation.

For the lower limit of $2.8, the z-score is

(2.8 - 3.4) / 0.20 = -3.00.

For the upper limit of $3.0, the z-score is

(3.0 - 3.4) / 0.20 = -2.00.

We can then use a standard normal distribution table or calculator to find the probability of the z-score being between -3.00 and -2.00, which is the same as the probability of the price being between $2.8 and $3.0.

The probability of a z-score being between -3.00 and -2.00 is approximately 0.1359.
