25 is 5 times as 5 so here is the answer
Answer: 6.4
Step-by-step explanation:
If f(t) = P Where r= rate and t= time
Given: P=5, r= 0.05
We are required to determine f(5) to the nearest tenth
By comparing f(t) and f(5), it implies we take out t=5
Therefore:
f(t) = P = 5*
=6.42012708344
=6.4 ( to the nearest tenth)
Note: e is the exponential growth symbol
First, the characteristic solution to the homogeneous part:
has characteristic equation
with roots
. So the characteristic solution has the form
Now for the nonhomogeneous part. Using the method of undetermined coefficients, we can try a particular solution of the form
which has derivatives
Substituting
and its derivatives into the equation gives
which means
so that the particular solution must be
Now the general solution will be
Suppose a quadratic function like
the vertex will be
The answer to this very unique and wonderful math equation or problem is simply the answer of the variable y = 7
