Answer: To determine how much of the radioactive europium will be left after 75 years, we can use the half-life formula:

Amount remaining = Initial amount * (1/2)^(time elapsed / half-life)

Given that the half-life of the radioactive europium is 15 years and the initial amount is 90,624 grams, we can substitute these values into the formula:

Amount remaining = 90,624 * (1/2)^(75 / 15)

Calculating the exponent first:

(75 / 15) = 5

Substituting this back into the formula:

Amount remaining = 90,624 * (1/2)^5

Simplifying the exponent:

(1/2)^5 = 1/32

Substituting this back into the formula:

Amount remaining = 90,624 * 1/32

Simplifying the calculation:

Amount remaining = 2,832 grams

Therefore, after 75 years, there will be approximately 2,832 grams of the radioactive europium left.

Answer:

(4, - 2 )

Step-by-step explanation:

4x + 2y = 12 → (1)

- 4x + y = - 18 → (2)

adding the 2 equations term by term will eliminate x

(4x - 4x) + (2y + y) = 12 - 18

0 + 3y = - 6

3y = - 6 ( divide both sides by 3 )

y = - 2

substitute y = - 2 into either of the 2 equations and solve for x

substituting into (1)

4x + 2(- 2) = 12

4x - 4 = 12 ( add 4 to both sides )

4x = 16 ( divide both sides by 4 )

x = 4

solution is (4, - 2 )

The total number of letters written by Yuan can be shown as the algebraic expression is 16n letters.

An algebraic expression is a combination of terms separated by mathematical operations like addition (plus: +), subtraction (minus: -), multiplication (product: *), and divide (by: /).

Terms are combinations of variables and numeric values.

In the question, we are given that Yuan wrote 16 letters to friends each month for n months in a row.

We are asked to write an algebraic expression to show how many total letters Yuan wrote.

The number of letters written by Yuan each month = 16 letters.

The number of months for which Yuan wrote letters to his friend = n months.

The total number of letters will be the product of the two.

Thus, the total number of letters written by Yuan can be shown as the algebraic expression 16 * n letters = 16n letters.

The critical point of f at z = 1 is a local minimum.

To find the critical points of the function f(z, 3) = 4z^2 - 8z + 1, we need to find the values of z where the first partial derivatives with respect to z are equal to zero. Let's solve it step by step.

Take the partial derivative of f with respect to z:

∂f/∂z = 8z - 8

Set the derivative equal to zero and solve for z:

8z - 8 = 0

8z = 8

z = 1

The critical point of f occurs when z = 1.

To determine whether the critical point is a local minimum, local maximum, or a saddle point, we can use the second partial derivative test. We need to calculate the second partial derivative ∂²f/∂z² and evaluate it at the critical point (z = 1).

Taking the second partial derivative of f with respect to z:

∂²f/∂z² = 8

Evaluate the second derivative at the critical point:

∂²f/∂z² at z = 1 is 8.

Analyzing the second derivative:

Since the second derivative ∂²f/∂z² = 8 is positive, the critical point (z = 1) corresponds to a local minimum.

Therefore, the critical point of f at z = 1 is a local minimum.

The value of x is 17, y is 2 and length of DF is 20.

Basic Proportionality Theorem (can be abbreviated as BPT) states that, if a line is parallel to a side of a triangle which intersects the other sides into two distinct points, then the line divides those sides in proportion.

For x

DG = GE ( Given )

DG + GE = DE

DE = 2(DG)

DG/DE = 1/2

hence GH/EF = 1/2

By Basic Proportionality Theorem ( BPT )

(x – 3) / 28 = 1/2

after cross multiplication

2(x – 3) = 28

2x – 6 = 28

2x = 34

x = 17

For y

By Basic Proportionality Theorem (BPT) to side DF

DF = 2(DH)

DH/DF = 1/2

(y + 8) / (y + 8 + x – 7) = 1/2

after cross multiplication

2(y + 8) = y + 8 + x – 7

put x = 17

2(y + 8) = y + 8 + 17 – 7

2(y + 8) = y + 18

2y + 16 = y + 18

2y = y + 2

2y – y = 2

y = 2

DF = 2(2+8)

     = 2(10)

     = 20

Hence, x is 17, y is 2 and DF is 20.

The average cost of their dinners, or the amount each person would pay if splitting the bill equally, is $31.

The average cost of their dinners can be found by adding up the costs of their meals and dividing the sum by the number of people, which in this case is three. The costs of Mike's, Roberta's, and Paul's meals are $27, $38, and $28, respectively.

To find the average cost, we add up the costs: $27 + $38 + $28 = $93. Then we divide this total by the number of people, which is three.

So, the average cost of their dinners is $93 ÷ 3 = $31.

Therefore, the average cost of their dinners, or the amount each person would pay if splitting the bill equally, is $31. This means that if they decide to divide the total cost of their meals equally among themselves, each person would contribute $31.

The results generated in the map phase are combined in the _reduce_ phase.

In maps, the "reduced phase" refers to a technique used to remove the phase ambiguity present in interferometric synthetic aperture radar (InSAR) data. InSAR uses radar to measure the distance between a satellite or aircraft and the ground and can be used to create detailed maps of changes in the surface of the earth over time.

However, because InSAR data is collected using radar waves, which are sensitive to the phase of the signal, the data can be affected by phase ambiguities. The reduced phase technique is used to remove these ambiguities and create more accurate maps.

The  domain relation a consists of all pairs of real numbers whose absolute difference is less than or equal to 2.

The given relation is defined as follows:

a: {(x, y) | x, y ∈ ℝ and |x - y| ≤ 2}

In this relation, the domain is specified as the set of all real numbers, which means that any real number can be used as the input for this relation.

To clarify, if we take any two real numbers, x and y, and the absolute value of their difference, |x - y|, is less than or equal to 2, then the ordered pair (x, y) is included in the relation.

For example, if we choose x = 3 and y = 1, then |3 - 1| = 2, which satisfies the condition |x - y| ≤ 2. Therefore, the ordered pair (3, 1) is in the relation a. Similarly, if we choose x = 2 and y = 4, |2 - 4| = 2, so the ordered pair (2, 4) is also in the relation.

In summary, the relation a includes all ordered pairs (x, y) where the absolute difference between x and y is less than or equal to 2, and it can be used with any real numbers as input.

The relation a is a subset of the Cartesian product of the set of all real numbers with itself, denoted by R × R. In other words, a is a set of ordered pairs (x, y) such that |x - y| ≤ 2, where x and y are real numbers.

For any real numbers x and y, the expression |x - y| represents the absolute value of the difference between x and y. The absolute value of a number is always non-negative, so the inequality |x - y| ≤ 2 means that the distance between x and y on the real number line is less than or equal to 2.

Therefore, the domain of the relation a is the set of all real numbers, since the definition of the relation applies to any two real numbers x and y.

The given relation is defined as follows:

a: {(x, y) | x, y ∈ ℝ, |x - y| ≤ 2}

This relation represents all pairs of real numbers (x, y) where the absolute difference between x and y is less than or equal to 2. In other words, it includes all pairs (x, y) such that the distance between x and y on the real number line is at most 2.

For example, (1, 3) is in the relation a because |1 - 3| = 2, which satisfies the condition |x - y| ≤ 2. Similarly, (5, 6) is in the relation a because |5 - 6| = 1 ≤ 2.

On the other hand, (4, 8) is not in the relation a because |4 - 8| = 4 > 2, violating the condition.

The longer diagonal connects vertices A and C, and let E and F be the feet of the perpendiculars from vertices B and D to the longer diagonal AC.

From the figure,

BE = 20 m

DF = 30 m

AE = EC = 120/2 = 60 m

The area of a trapezoid.

AB² = AE² + BE²

60² + 20² = 4000

AB = √(4000)

AB = 20 √10

The cup of water reaches a temperature of 173 F after 4.5  minutes.

Temperature is a measure of the average kinetic energy of particles in a system. It is an important physical quantity used to describe the state of a system and is widely used in science, engineering, and everyday life. Temperature is a thermodynamic property of a system that shows how much energy is available to do work. In everyday terms, temperature is a measure of how hot or cold something is.

k = -0.2416

The equation for the cooling rate of the cup of water is:

T(t) = 203- 0.2416t
