2)   €17,908.48

3)  0.5%

4)  120

[tex]\textsf{5)} \quad 10000(1.005)^{120}[/tex]

6)  €18,193.97

7)  More money.

Step-by-step explanation:

[tex]\boxed{\begin{minipage}{7 cm}\underline{Annual Compound Interest Formula}\\\\$ A=P\left(1+r\right)^{t}$\\\\where:\\\\ \phantom{ww}$\bullet$ $A =$ final amount \\ \phantom{ww}$\bullet$ $P =$ principal amount \\ \phantom{ww}$\bullet$ $r =$ interest rate (in decimal form) \\ \phantom{ww}$\bullet$ $t =$ time (in years) \\ \end{minipage}}[/tex]

Given:

Substitute the given values into the compound interest formula to write an expression that describes the given scenario over t years:

[tex]\implies A=10000(1+0.06)^t[/tex]

[tex]\implies A=10000(1.06)^t[/tex]

To calculate how much money will be in the fund after 10 years, substitute t = 10 into the equation from question 1:

[tex]\implies A=10000(1.06)^{10}[/tex]

[tex]\implies A=10000(1.79084769...)[/tex]

[tex]\implies A=17908.4769...[/tex]

Therefore, there will be €17,908.48 in the emergency fund after 10 years.

If the annual rate is 6%, the monthly interest rate is the annual rate divided by 12 (since there are 12 months in a year):

[tex]\implies \dfrac{6\%}{12}=0.5\%[/tex]

Given that are 10 years in the scenario, the exponent will be the number of months in 10 years:

[tex]\implies 10 \times 12 = 120[/tex]

0.5% = 0.005

Therefore, the complete expression that describes the scenario, given an annual interest rate of 6% that compounds monthly over 10 years is:

[tex]\implies 10000(1 + 0.005)^{120}[/tex]

[tex]\implies 10000(1.005)^{120}[/tex]

To calculate how much money will be in the emergency fund after 10 years if the interest compounds monthly, calculate the expression from question 5:

[tex]\implies 10000(1.005)^{120}[/tex]

[tex]\implies 10000(1.81939673...)[/tex]

[tex]\implies 18193.9673...[/tex]

Therefore, there will be €18,193.97 in the emergency fund after 10 years.

Amount in fund when compounded annually = €17,908.48

Amount in fund when compounded monthly = €18,193.97

Therefore, there is more money in the emergency fund when it is compounded monthly as the compounding frequency is greater (interest is earned on both the principal and the interest, so the more frequent the compounding periods are, the more interest is earned).

The general rule about compounding in exponential functions is the higher the number of compounding periods, the greater the amount of compound interest.  

In terms of compounding interest in investment:

The perimeter of the triangle is 96, rounded to the nearest hundredth.

To calculate the perimeter of the triangle, we need to first calculate the length of the hypotenuse.

The hypotenuse of a right triangle is calculated using the Pythagorean theorem, which states that the square of the hypotenuse is equal to the sum of the squares of the two sides.

Therefore, for this triangle, we have:

(Hypotenuse)² = (24)² + (32)²

Therefore, the Hypotenuse = √(24² + 32²)

Hypotenuse = √(576 + 1024)

Hypotenuse = √1600

Hypotenuse = 40

To calculate the perimeter, we need to add up all three sides of the triangle.

the perimeter = 24 + 32 + 40

the perimeter = 96

Therefore, the perimeter of the triangle is 96, rounded to the nearest hundredth.

Answer:

$27,400.

Step-by-step explanation:

We know that the salesman makes $25,000 annually plus 6% commission on his total sales.

We also know that he sold $40,000 worth of trampolines this year.

So we can find out his commission by multiplying the value of sales with 6% commission rate.

Commission = 0.06 * $40,000 = $2400

To find out his total earnings we need to add his annual salary with commission earned.

Total earnings = $25,000 + $2400 = $27,400

So the salesman's total earnings for this year is $27,400.

In graph theory, a 2-factor is a subgraph of a given graph that includes every vertex of the original graph and has the property that every vertex has even degree (i.e. degree is a multiple of 2).

The term "2-factor" is used because it is a factor of the original graph that is made up of edges and every vertex has degree 2.

A 2-factor can also be defined as a set of cycles that cover all vertices of the graph. In other words, it is a collection of cycles such that every vertex belongs to exactly one cycle. A 2-factor can also be thought of as a cycle cover of a graph.

A graph that has a 2-factor is called a 2-factorizable graph. Not all graphs are 2-factorizable, for example a graph with an odd number of vertices can't have a 2-factor.

2-factors have many applications in various fields such as scheduling, coding theory, and computer science. They are also used to study the connectivity and robustness of graphs.

Trigonometry is a field of mathematics that examines correlations between triangle side lengths and angles (from the Ancient Greek words "trigonon" and "metron"). The field was created in the Hellenistic era in the third century BC as a result of the use of geometry in astronomical research.

Trigonometry has been used historically in fields like geodesy, surveying, celestial mechanics, and navigation.

Answer:

Step-by-step explanation:

first plug in w(x) into u(x):

u(w(x)) = 5(-5(x)+4)+3

then plug in -5 for x:

u(w(-5)) = 5(-5(-5)+4)+3

solve:

= 148

This is a composite function:

Composite functions are are functions that are written within each other like f(g(x).

To solve this problem, first solve the function within u(x), which would be w(x)

w(-5) = -5(-5) -4

        = 25 - 4

       = 21

Now, plug in that value into u(x) to get your final answer:

u(21) = 5(21) +3

Answer: u(w(-5) = 108

Colton can rent the car for a total of 6 days while still staying within his means.

We are aware that hiring a car costs $72.37 per day, and that each mile travelled costs $0.06. We also know that Colton has a $450 spending limit and intends to go 275 miles.

We may set up the following inequality to determine how long Colton can afford to hire the car for:

72.37d + 0.06(275) <= 450

This inequality indicates that the entire cost must be less than or equal to Colton's $450 budget. It represents the cost of renting the car as well as the cost of the miles driven.

We must isolate d on one side of the inequality in order to solve for it. To calculate the cost of the miles driven, first multiply 0.06 by 275:

72.37d + 16.5 <= 450

After that, we will take 16.5 away from either side of the inequality:

72.37d <= 433.5

A final division of 72.37 will be applied to both sides of the inequality:

d <= 6

Therefore, Colton can rent the car for a total of 6 days while still staying within his means.

Answer:

8x + 2y = 10  ==>  y = -4x + 5

12x - 3y = -25​  ==>  y = 4x + 25/3

Step-by-step explanation:

8x + 2y = 10  ==> solve for y

2y = 10 - 8x  ==> subtract 8x on both sides

(2y = 10 - 8x) / 2 ==> divide the equation by 2 to make 2y into y

y = 5 - 4x  ==> simplify

y = -4x + 5  ==> put the equation in y=mx+b form

12x - 3y = -25​  ==> solve for y

12x = -25 + 3y  ==> make y positive by adding 3y on both sides

12x + 25 = 3y ==> add 25 on both sides to isolate y

(3y = 12x + 25) / 3  ==> divide the equation by 3 to make 3y into y

y = 4x + 25/3 ==> simplify

What is a Linear Expression?

A linear expression is an algebraic statement where each term is either a constant or a variable raised to the first power. In other words, none of the exponents can be greater than 1.

For example, t² is a variable raised to the second power, but t is a variable raised to the first power.

x² + y² = 18 ----- 1

x + 2 = - 3x ---- 2

From equation 2

x + 2 = - 3x

x + 3x = -2

4x = -2

x = -2/4

x = -1/2

Substitute x in equation 1

(-1/2)² + y² = 18

1/4 + y² = 18

y² = 18 - 1/4

y² = (72 - 1)/4

So the total number of ways to order the art such that the Escher prints are consecutive is 120 × 6 = 720.
