Answer:
Step 1: 0.246 = 246⁄1000
Step 2: Simplify 246⁄1000 = 123⁄500
Answer:
Principal = $1,000
Rate of interest = 14% = 0.14
Time = 3 years

A = Amount or future value
P = Principal
r = rate of interest in decimals
t = time
Substitute the values in the formula


Future Value is $1481.544
Compound interest = Amount - Principal = $1481.544- $1000 = $481.544
Formula of simple interest : 
Substitute the values :


So, Simple interest = $420
Compound interest - Simple interest
= $481.544- $420
= $61.544
So, Compound Interest is $61.544 more than simple interest.
In bmultiplying, you always have to move the decimal of the product the amount of place values the decimal has in each factor, for example, 1.50 times 1.50= 2.25, the factors together have 4 decimals, so you move the decimal 4 times to the right (try it, it gets rid of alot of zeros in the answer.)
Given:
The inequality is:

To find:
The graph of the given inequality.
Solution:
We have,

Subtract both sides by 1.


Divide both sides by 3.

The value of t is less than or equal to
.
Since
, it means
is included in the solution, therefore there is a closed circle at
and an arrow approaches to left from
.
Therefore, the correct option is A.
Here is all I got for you. From the starting expression to the simplest one.
t^2 + 4tv + 4^2 =
t^2 + 4tv + 16 =
t(t + 4v) + 16
