Answer: Hello!
A second order differential equation has the next shape:

where p(t), q(t) and g(t) are functions of t, that can be constant numbers for example.
And is called homogeneus when g(t) = 0, so you have:

Then a second order differential equation is homogeneus ef every term involve either y or the derivatives of y.
The opposite of 12.1 is 12.2
To solve:
(x-10)(x-10)
Answer: x^2-20x+100
Answer: its c or 35
Step-by-step explanation: because at 10 salespeople its 40, so 9 salespeople is 35
Answer:
