The scale factor of a room for a scale drawing is 2.3. The actual length of a wall in the room is 46 feet and the actual width o
dimaraw [331]

Answer:

There's two ways to solve this.

Step-by-step explanation:

First way:

Let's divide the width and length by 2.3.

46÷2.3=20

69÷2.3=30

20×30

600 ft²

Second Way:

Let's find the area of the actual room.

46×69

3,174 ft²

Let's find the scale drawing squared.

2.3²=5.29

3,174÷5.29

600 ft²

How long will it take for an investment to triple, if interest is compounded continuously at 8%?
maw [93]

Answer:

<em>It will take 14 years before the investment triples</em>

Step-by-step explanation:

<u>Continuous Compounding</u>

Is the mathematical limit that compound interest can reach if it was calculated and reinvested into an account's balance over a theoretically infinite number of periods.

The formula for continuous compounding is derived from the formula for the future value of a compound interest investment:

FV = PV\cdot e^{i.t}

Where:

FV = Future value of the investment

PV = Present value of the investment

i     = Interest rate

t     = Time

It's required to find the time for an investment to triple, that is, FV = 3 PV, knowing the interest rate is i=8%=0.08.

Substituting the known values:

3PV = PV\cdot e^{i.t}

Dividing by PV:

3 = e^{i.t}

Taking logarithms:

\ln 3=i.t

Solving for t:

\displaystyle t=\frac{\ln 3}{i}

\displaystyle t=\frac{\ln 3}{0.08}

t = 13.7 years

Rounding up:

It will take 14 years before the investment triples
