What does investment mean in everyday language?

A purchase made with the intention of earning money or gaining notoriety is referred to as an investment. The acquisition of things that are not used right away but will be utilized to create wealth down the road is known as an investment in an economic perspective. There are numerous investment options available.

Rate in percentage (R) = 5.5%

Principal Amount (P) = 5 200

Total time period (t) = 9 years

Number of times interest is compounded per t (n) = 1

r = R/100

r = 5.5/100

r =  0.055 rate per year,

Then solve the equation for A

A = P(1 + r/n)^(nt)

A = 5200(1 + 0.055/1)⁽¹⁾⁽⁹⁾

A = 5200(1 + 0.055)⁹

A = 5200(1.055)⁹

A =  5200 * 3.45 x 10^5

   = 17940 x 10^5

Hence, after a time period of 9 years Mr. Lucas' investment will be 17940 x 10^5

The number of days would be 10 and the maximum percent of the population infected would be 25.752%.

What are exponential functions?

The exponential function, denoted by \(e^x\), is a mathematical function. Unless otherwise specified, the term refers to a positive-valued function of a real variable, though it can be extended to complex numbers or generalized to other mathematical objects such as matrices or Lie algebras.

\(p(t) = 7te^{-\frac{t}{10}}\)

percentage of infected people a maximum when p '(t) = 0

                    \(p '(t) = 7(1)e^\frac{-1}{10} +7te^\frac{-t}{10}(\frac{-1}{10})\\\\p'(t)=e^{-\frac{t}{10}}(7 -\frac{7t}{10})\\\\e^{-\frac{t}{10}}(7 -\frac{7t}{10})=0\\\\7 -\frac{7t}{10}=0\\\\t = 10\)

Hence percentage of infected people reaches a maximum after 10 days

maximum percent of the population infected = p(10)

    \(p(10) = 7(10)e^{-\frac{10}{10}}\\\\p(10)=\frac{70}{e}\\\\P(10)=25.752\%\)

Hence, the number of days would be 10 and the maximum percent of the population infected would be 25.752%.

In this scenario, Kathy and Stan engage in a race, with Kathy starting 1.00 second after Stan. Stan maintains a constant acceleration of 3.8 m/s^2, while Kathy accelerates at a rate of 4.49 m/s^2. We need to determine the time at which Kathy overtakes Stan, the distance she travels before catching him, and the speeds of both cars at the moment Kathy overtakes Stan.

A) Kathy will overtake Stan when her displacement equals Stan's displacement. To calculate the time at which this occurs, we can use the equation:

s = ut + (1/2)at^2,

where s represents the displacement, u represents the initial velocity, a represents the acceleration, and t represents time. Rearranging the equation to solve for t:

t = √((2s)/a),

we find that Kathy overtakes Stan after approximately 7.26 seconds.

B) To determine the distance Kathy travels before catching Stan, we can use the equation:

s = ut + (1/2)at^2.

Substituting the values for Kathy's acceleration and the time calculated in part A, we find that Kathy covers a distance of approximately 98.24 meters.

C) At the instant Kathy overtakes Stan, their speeds will be equal. We can calculate their speeds using the equation:

v = u + at,

where v represents the final velocity, u represents the initial velocity, a represents the acceleration, and t represents time. Substituting the values for Kathy's acceleration and the time calculated in part A, we find that Kathy's speed at the moment she overtakes Stan is approximately 32.49 m/s. Since Kathy started 1.00 second after Stan, Stan's speed at that instant would be his initial speed plus the product of his acceleration and the time difference, resulting in approximately 25.8 m/s.

Michael needs to analyze the population data, demographics of the city, and the competition in the area to determine whether or not to open a new store.

Michael is trying to determine where to open two new store locations. He has population data to determine the amount of revenue he will receive for each location.

He is charged a $1000 fee for opening a new store at a certain location. However, he is unsure whether the population of the city would be large enough to warrant opening a new store at that location.

The first step that Michael needs to take is to analyze the population data that he has.

Based on the population data, he needs to make an informed decision about whether or not to open a new store at that location. This would require him to take into consideration the average income of the population as well as the demographics of the city.

Another important factor that Michael needs to take into consideration is the competition in the area. If there are already several stores in the area, then opening a new store might not be a good idea.

This is because the competition would be too high and he would not be able to generate enough revenue to make up for the cost of opening a new store.

However, if there are no stores in the area, then Michael might consider opening a new store. This would require him to invest a significant amount of money, but he could also generate a significant amount of revenue in return.

Additionally, he needs to take into consideration the cost of opening a new store and whether or not he can generate enough revenue to make up for that cost.

Overall, Michael needs to carefully analyze all the data that he has before making an informed decision about where to open new store locations.

In conclusion, Michael needs to analyze the population data, demographics of the city, and the competition in the area to determine whether or not to open a new store. If the population is large enough and there is no competition in the area, then he should consider opening a new store. However, if there is already a significant amount of competition in the area, then he should avoid opening a new store.

The product is 3x * 4x^(3/2) = 12x^(5/2)

How to do the product of root?

When multiplying two terms with the same base and different exponents, you can add their exponents.

For example, √(a^m) * √(a^n) = √(a^m * a^n) = √(a^(m+n)) = a^((m+n)/2)

The product of 3√(x^2) * 4√(x^3) is equal to:

12x^(5/2)

This is because when you multiply two terms with the same base, you can add their exponents:

3√(x^2) * 4√(x^3) = (3*4)√(x^(2+3/2)) = 12x^(5/2)

This is because

√(x^2) = x^(2/2) = x

√(x^3) = x^(3/2) = x^(3/2)

so we can write 3root x^2 = 3x and 4root x^3 = 4x^(3/2)

Fatma's account needs to earn a rate of return of approximately 0.2957% per month to stretch her money out for 17 years.

To determine the required rate of return for Fatma's account, we can use the future value formula:

FV = PV * (1 + r)^n

Where:

FV = Future value (amount needed for 17 years of expenses)

PV = Present value (initial amount Fatma has)

r = Rate of return

n = Number of compounding periods (monthly withdrawals over 17 years)

Given:

PV = $182,000.00

Monthly expenses = $1,350.00

Number of years = 17

Number of compounding periods = 17 years * 12 months = 204 months

We can rearrange the formula to solve for the required rate of return (r):

r = (FV / PV)^(1/n) - 1

Substituting the given values:

FV = $1,350.00 * 204 = $275,400.00

r = ($275,400.00 / $182,000.00)^(1/204) - 1

Calculating this expression:

r ≈ 0.002957 (approximately 0.2957%)

Therefore, Fatma's account needs to earn a rate of return of approximately 0.2957% per month to stretch her money out for 17 years.
