I think you are looking for a percentage but it works be about 266% or 2.66 books per month
Answer:
See below.
Step-by-step explanation:
7 ) 29.0
= 4 1/7
= 4.142857142857.........
The 142857 repeats itself without bounds.
Answer:
80
Step-by-step explanation:
You mean the "interest on"
I=800×.1×1=80
First look for the fundamental solutions by solving the homogeneous version of the ODE:
The characteristic equation is
with roots and , giving the two solutions and .
For the non-homogeneous version, you can exploit the superposition principle and consider one term from the right side at a time.
Assume the ansatz solution,
(You could include a constant term <em>f</em> here, but it would get absorbed by the first solution anyway.)
Substitute these into the ODE:
is already accounted for, so assume an ansatz of the form
Substitute into the ODE:
Assume an ansatz solution
Substitute into the ODE:
So, the general solution of the original ODE is
Answer:
gallons
Step-by-step explanation:
Considering she waters her plants with 25 1/2 gallons i.e 51/2
and with the new system, she does it with 19 3/4 i.e 79/4
taking the difference:
= gallons per day
For 30 days:
30 x = 172.5 or gallons
