$500 is compounded annually for 46 years. No other deposits are made.

The rate needed for the balance to triple in that time can be calculated as follows:

The interest rate as a percent can be calculated as follows:

For the principal to be tripled, the amount will be 500(3) = 1500 dollars

[tex]r = n((\frac{A}{P} )^{\frac{1}{nt} } -1)[/tex]

where

P = 500

A = 1500

n = 1

t = 46 years

r[tex]r = 1((\frac{1500}{500})^{\frac{1}{1(46)} } - 1 )[/tex]

[tex]r = 1((\frac{1500}{500})^{\frac{1}{46} } - 1 )[/tex]

r = 0.0241704

Then convert r to R as a percentage

R = r * 100

R = 0.0241704 * 100

An equation that represents the situation is 780/x and the initial number of participants is 95.

Equation:

An equation is the combination of number, variables and the mathematical operators such as addition, subtraction, multiplication and division etc.

Given,

The chess club plans to fundraise $780, which is to be divided evenly among the members. Initially there are x participants, but then 2 more participants come forward, causing each participant to fundraise $8 less.

Here we need to find the equation that represents the situation and then we have to find the initial number of participants.

According to the given question,

Total amount for fundraise = $780

Number of participants = x

Here we know that the amount is divided evenly among the members.

So, the equation is written as.

=> 780/x

And the other part of the condition is, 2 more participants come forward, causing each participant to fundraise $8,

So, it can be written as,

=> 780 / (x+2)  = 8

=> x + 2 = 780/8

=> x + 2 = 97

=> x = 95

Therefore, there are 95 initial number of participants.

The number of point on this graph that represent a relative minimum is one, which is point b.

In Mathematics, a function simply refers to a mathematical expression which is typically used for defining and representing the relationship that exists between two or more variables such as an ordered pair (x, y)on a graph.

A relative minimum can be defined as the lowest point or valley point on the graph of a function. Additionally, all of the points that are located to the left and right of the lowest point (valley point) on a graph must be larger than the relative minimum.

Answer:

The end behavior of the function is that it approaches positive infinity as x decreases to negative infinity, and it also approaches positive infinity as x approaches positive infinity.

Step-by-step explanation:

The end behavior of a function is what happens to the value of the function as x approaches negative infinity and as x approaches positive infinity.

Graphing the function is very helpful to visualize the end behavior.

Here, the graph has the shape of a V with the vertex on the x-axis going up in value on both sides forever.

The function here is f(x) = 3|x|.

Let's try a few values for x to get an idea.

We will deal with x approaching positive infinity first.

f(0) = 3|0| = 0

Let's get larger and larger values for x, approaching positive infinity.

f(10) = 3|10| = 30

f(10,000) = 3|10,000| = 30,000

f(1,000,000) = 3|1,000,000| = 3,000,000

As you can see, as x increases, the value of f(x) also increases. As x approaches positive infinity, f(x) also approaches positive infinity.

Now let's look at values of x approaching negative infinity.

f(0) = 3|0| = 0

Let's get smaller and smaller values for x, approaching negative infinity.

f(-10) = 3|-10| = 30

f(-10,000) = 3|-10,000| = 30,000

f(-1,000,000) = 3|-1,000,000| = 3,000,000

As you can see, as x decreases, the value of f(x) increases. As x approaches negative infinity, f(x) approaches positive infinity.

The end behavior of the function is that it approaches positive infinity as x decreases to negative infinity, and it also approaches positive infinity as x approaches positive infinity.

If your cost of money is 6.4 percent, what is the current value of the lease is equal to $820.0054.

In Economics, a lease can be defined as a contractual agreement between a lessor and lessee, which avails the lessee an opportunity to make use of an asset, while making payments in instalment to the lessor for a specific period of time.

Mathematically, the current (present) monetary value of a lease can be calculated by using this formula:

Current value, PV = [Annuity × (1 + r) × [1 - (1 + r)^{-n}]/r]

Where:

Note: r = 0.064/12 = 0.0053333

Substituting the given parameters into the formula, we have;

Current value, PV = [144 × (1 + 0.0053333) × [1 - (1 + 0.0053333)^{-36}]/0.0053333]

Current value, PV = [144 × (1.0053333) × [1 - (1.0053333)^{-36}]/0.0053333]

Current value, PV = [144 × (1.0053333) × [1 - 0.8257290]/0.0053333]

Current value, PV = [144 × (1.0053333) × [0.174271/0.0053333]

8b = 5a ( divide both sides by 8 )

b = [tex]\frac{5}{8}[/tex] a

3c = 4b ( divide both sides by 3 )

c = [tex]\frac{4}{3}[/tex] b = [tex]\frac{4}{3}[/tex] × [tex]\frac{5}{8}[/tex] a = [tex]\frac{5}{6}[/tex] a
