               Which expression represents "12 less than the product of n and 5"?

\blue{\textsf{\textbf{\underline{\underline{Answer:-}}}}

12-5n

\blue{\textsf{\textbf{\underline{\underline{How\:to\:Solve:-}}}}

                        First of all, the "product" indicates that you multiply these           numbers.

Here we are asked to multiply a number n times 5. This can be written as follows:

\red{\textsf{\textbf{5n}}}

Now, "12 less" indicates that we subtract 12 from something; in this case, this "something" is 5n:

\red{\textsf{\textbf{\underline{\underline{12-5n}}}}

<h3>Good luck.</h3>

If the population of a particular country is growing at 3.2 % compounded​ continuously, how long will it take the population to
Lisa [10]

Answer:

It will take 34.33

Step-by-step explanation:

* Lets talk about the compound continuous growing

- Compound continuous growing can be calculated using the formula:

 A=Pe^{rt}

# A = the future value

# P = the initial amount

# r = the growing rate  in decimal

# t = the time

* Lets solve the problem

- The population of a particular country is growing at 3.2 %

 compounded​ continuously

∴ r = 3.2/100 = 0.032

- We need to find how long will it take the population to triple​

∵ The initial population is P

∴ A = 3P

∵ A=Pe^{rt}

∴ 3P=Pe^{0.032t}

- Divide both sides by P

∴ 3=e^{0.032t}

- Insert ㏑ for both sides

∴ ln(3)=ln(e^{0.032t})

- Remember ln(e^{n})=n

∴ ㏑(3) = 0.032t

- Divide both sides by 0.032

∴ t = ㏑(3)/0.032 = 34.33

* It will take 34.33

You bought your car for $12500 and it is depreciating at 13% per year. How long until it is only worth half of what you paid for
il63 [147K]

Answer:

5 years

Step-by-step explanation:

We are given;

  • Initial value of the car = $12,500
  • Rate of Depreciation = 13% per year
  • New value (after depreciation) = $6,250 (half the initial value)

We are required to determine the time taken for the value of the car to depreciate to half the original value.

  • We need to know the depreciation formula;
  • New value = Initial value ( 1 - r/100)^n

Therefore;

$6,250 = $12,500(1 - r/100)^n

0.5 = (1 - 13/100)^n

0.5 = 0.87^n

Introducing log on both sides;

log 0.5 = n log 0.87

Therefore;

n = log 0.5 ÷ log 0.87

  = 4.977

  = 5 years

Therefore, it takes 5 years for the value of the car to depreciate to half the initial value.
