Answer:
D is correct Answer. Parallel line on graph means infinity many solutions.
Answer:
Step-by-step explanation:
(A) The difference between an ordinary differential equation and an initial value problem is that an initial value problem is a differential equation which has condition(s) for optimization, such as a given value of the function at some point in the domain.
(B) The difference between a particular solution and a general solution to an equation is that a particular solution is any specific figure that can satisfy the equation while a general solution is a statement that comprises all particular solutions of the equation.
(C) Example of a second order linear ODE:
M(t)Y"(t) + N(t)Y'(t) + O(t)Y(t) = K(t)
The equation will be homogeneous if K(t)=0 and heterogeneous if 
Example of a second order nonlinear ODE:

(D) Example of a nonlinear fourth order ODE:
![K^4(x) - \beta f [x, k(x)] = 0](https://tex.z-dn.net/?f=K%5E4%28x%29%20-%20%5Cbeta%20f%20%5Bx%2C%20k%28x%29%5D%20%3D%200)
1:100 because 20 divide by 20=1 and 2000 divide by 20 =100
For the ODE

multiply both sides by <em>t</em> so that the left side can be condensed into the derivative of a product:


Integrate both sides with respect to <em>t</em> :

Divide both sides by
to solve for <em>y</em> :

Now use the initial condition to solve for <em>C</em> :



So the particular solution to the IVP is
