Find the savings plan balance after 18 months with an APR of 6% and monthly payments of $800. Assume an ordinary annuity.
jok3333 [9.3K]

The formula for this calculation is Future Value = Payment • [((1 + I)n - 1)/I], where I = interest rate, and n = periods.

 

In this case, P = $800/month, n = 18 months, and I = 6% (0.06) per year.

 

Since the information involves months instead of years, it is necessary to divide the interest rate by 12 to obtain the monthly rate. So, 0.06 ÷ 12 = 0.005

 

We can then enter the information into our formula to obtain:

FV = $800 • [((1.005)18 - 1)/.005]

FV = $800 • [(1.0939 - 1)/.005]

FV =$800 • (0.0939/0.005)

FV = $800 • 18.785

FV ≅ $15,028

Solve the ODE y'+xy=x² with y(0)=2​
goldenfox [79]
If you take the derivative of your equation, you get:

2′″−″−′+′=0
2
y
′
y
″
−
x
y
″
−
y
′
+
y
′
=
0

or

″(2′−)=0.
y
″
(
2
y
′
−
x
)
=
0.

Let =′
v
=
y
′
and we have ′(2−)=0,
v
′
(
2
v
−
x
)
=
0
,
so either ′=0
v
′
=
0
and =
v
=
c
or =/2
v
=
x
/
2
.

Then ′=
y
′
=
c
and so =+
y
=
c
x
+
d
or ′=/2
y
′
=
x
/

and =2/4.
y
=
x
2
/

Plugging the first into the original equation gives =−2
d
=
−
c

. So there are two solutions =−2
y
=
c
x
−
c
2
for some constant
c
and =2/4
y
=

/

. I don't know if this is all the solutions
