The amount of the substance that will be left after 5 half life is 5.94 grams

Radioactive decay is the process by which an unstable atomic nucleus loses energy by radiation.

The time required for half of the original population of radioactive atoms to decay is called the half-life.

Half life = 1/2

5 half life = 1/2 × 1/2 × 1/2 × 1/2 × 1/2

= 1/32

This means 1/32 of tht original mass will be left after 5 half life.

Therefore;

The mass of the substance left = 190 × 1/32

= 5.94 grams

therefore 5.94g of the mass of the substance will be left.

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 chain rule is a powerful tool for computing derivatives of composite functions, and it is widely used in calculus and its applications.

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

The probability of randomly selecting a marble that is NOT red is C. P(not red) = 11/20.

There are 9 red marbles out of a total of 20 marbles. Thus, the probability of selecting a red marble is 9/20.

To find the probability of selecting a marble that is NOT red, we can subtract the probability of selecting a red marble from 1 (since the probability of selecting any marble must be 1).

P(not red) = 1 - P(red) = 1 - 9/20 = 11/20

Therefore, the probability of randomly selecting a marble that is NOT red is C. P(not red) = 11/20.

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.

The relation ∼ on R × R, given by (x1,y1) ∼ (x2,y2) ⇔ (x1)²(y1)² = (x2)²(y2)², is an equivalence relation.

To show that the given relation is an equivalence relation, we need to prove that it satisfies the three conditions of reflexivity, symmetry, and transitivity.

Reflexivity: For any (x,y) in R × R, we have (x)²(y)² = (x)²(y)², which implies that (x,y) ∼ (x,y).

Symmetry: If (x1,y1) ∼ (x2,y2), then (x1)²(y1)² = (x2)²(y2)². This implies that (x2)²(y2)² = (x1)²(y1)², and hence (x2,y2) ∼ (x1,y1).

Transitivity: If (x1,y1) ∼ (x2,y2) and (x2,y2) ∼ (x3,y3), then (x1)²(y1)² = (x2)²(y2)² and (x2)²(y2)² = (x3)²(y3)². Multiplying these equations, we get (x1)²(y1)² = (x3)²(y3)², which implies that (x1,y1) ∼ (x3,y3).

Since the given relation satisfies all three conditions, it is an equivalence relation.

However, if the decisions drawn from both methods differ (e.g., one rejects the null hypothesis while the other does not), then the conclusions are not the same.

In order to compare the conclusions obtained using the p-value method with your initial conclusion, it is essential to first understand the p-value's role in hypothesis testing. The p-value is a probability that helps in determining the statistical significance of your test results. A smaller p-value (typically ≤ 0.05) indicates strong evidence against the null hypothesis, leading to its rejection in favour of the alternative hypothesis. Conversely, a larger p-value (typically > 0.05) suggests weak evidence against the null hypothesis, and therefore, it cannot be rejected.
When comparing the conclusions, assess if both methods lead to the same decision regarding the null hypothesis. If your initial conclusion rejects the null hypothesis and the p-value method yields a p-value ≤ 0.05, then the conclusions are the same. Alternatively, if your initial conclusion does not reject the null hypothesis and the p-value method results in a p-value > 0.05, the conclusions also align.
However, if the decisions drawn from both methods differ (e.g., one rejects the null hypothesis while the other does not), then the conclusions are not the same. In such cases, it is crucial to revisit the methodology and ensure the correctness of the approach taken, as it is vital to have consistent and accurate results in any statistical analysis.

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)).

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

Step-by-step explanation:

The line from center of the circle perpendicularly biscets chord. Hence, you can form a right-angled triangle with the radius as the hypotenuse (See picture)

So now you use Pythagoras theorem to solve for d:
a^2 +b^2 =c^2

12^2 +b^2 = 13^2

b^2 = 13^2 - 12^2

b = [tex]\sqrt{13^{2}-12^{2} }[/tex]

b= 5

Hence, d = 5

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 formula for permutations with repetition is a useful tool for counting the number of distinct sequences we can make when we have objects that are repeated.

It allows us to account for the fact that these objects can be arranged in different orders. The formula for permutations with repetition is:

n! / (n_1! * n_2! * ... * n_k!)

where n is the total number of objects in the sequence, n_1 is the number of objects of type 1, n_2 is the number of objects of type 2, and so on until n_k is the number of objects of type k.

This formula works because when we have objects that are repeated, we need to account for the fact that the same objects can be arranged in different orders. The denominator of the formula takes care of this by dividing out the number of permutations for each type of object.

To understand this better, let's consider an example. Suppose we have a sequence of 6 objects, consisting of 2 As, 2 Bs, and 2 Cs. We want to find the number of distinct sequences we can make.

Using the formula, we have:

6! / (2! * 2! * 2!) = 720 / 8 = 90

This means that there are 90 distinct sequences we can make using these 6 objects. To see why this works, let's consider one possible sequence:

A B C A B C

We can rearrange this sequence in different ways by swapping any of the As with each other, any of the Bs with each other, or any of the Cs with each other. Each of these rearrangements will give us a different sequence, but they will all have the same objects in them. The denominator of the formula takes care of this by dividing out the number of ways we can rearrange the As, the Bs, and the Cs separately.

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:

Expanding the dot product, we get:

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.
