Answer:
8/9 sorry if wrong
Step-by-step explanation:
Answer:
The doubling time of this investment would be 9.9 years.
Step-by-step explanation:
The appropriate equation for this compound interest is
A = Pe^(rt), where P is the principal, r is the interest rate as a decimal fraction, and t is the elapsed time in years.
If P doubles, then A = 2P
Thus, 2P = Pe^(0.07t)
Dividing both sides by P results in 2 = e^(0.07t)
Take the natural log of both sides: ln 2 = 0.07t.
Then t = elapsed time = ln 2
--------- = 0.69315/0.07 = 9.9
0.07
The doubling time of this investment would be 9.9 years.
The answer is D. A function is to where a line can be drawn upon the y axis and not touch two points.
X/26=28
•26=•26 (cancels each other out)
X=728
Answer:
Step-by-step explanation:
We know that for principal amount P , time period T and rate of interest 
, simple interest is given by 
.
Here ,
To find : simple interest rate i.e.,
On putting values of 
in formula , we get
Now we need to round off the answer to the nearest tenth .
So, simple interest rate is % = 
=
