Answer:
$835.71
Step-by-step explanation:
To solve this problem, we will use the compound interest formula:

<em>P = initial balance</em>
<em>r = interest rate (decimal)</em>
<em>n = number of times compounded annually</em>
<em>t = time</em>
First, lets change 4.75% into a decimal:
4.75% ->
-> 0.0475
Now, plug the values into the equation:


Lastly, subtract <em>A </em>from the principal:

The interest earned is $835.71
Answer:
radius = 6.5
Step-by-step explanation:
The equation of a circle centred at the origin is
x² + y² = r² ( where r is the radius )
x² + y² = 42.25 ← is in this form
with r² = 42.25 ( take the square root of both sides )
r =
= 6.5
First you have to make the units same. it will be easier if you make both the units to be days.
2 weeks= 14days
ratio will be
34:14
if you can make it into simpler form, then make it. this answer can simplified into smaller form,thus,
34:14
17:7
the answer is 17:7
