Answer:
I think it is Obtuse.
Step-by-step explanation:
120 Degrees - Obtuse
It would go by (-4,2) then (0,-2) next would be (2,4)
It would take 10.7 years.
The formula for continuously compounded interest is:

where P is the principal, r is the interest rate as a decimal number, and t is the number of years.
Using our information we have:

We want to know when it will double the principal; therefore we substitute 2P for A and solve for t:

Divide both sides by P:

Take the natural log, ln, of each side to "undo" e:

Divide both sides by 0.065:
Answer:
The required amount of interest is $5538.
Step-by-step explanation:
Given : $1,500 invested for 20 days at 6.75%, compounded daily.
To find : The amount of interest ?
Solution :
Applying compound interest formula,
Where, A is the amount
P is the principal P=$1500
r is the interest rate r=6.75%=0.0675 compounded daily
t is the time t=20 days
Substitute the value in the formula,
Therefore, The required amount of interest is $5538.
The operation applied is division.
a simple explanation is that the quantity decreases if you move the decimal to the left, which is the case for division
A power of 10^-4 is involved (you get a negative sign if you shift the decimal to the left: which is another explanation to the above question)
