B. 1.67
m : n = 2 : 1
( x, y ) = ( (1*3 + 2*(-2))/(2+1) ; (1 * (-1) + 2 * 3) /(2 + 1) ) =
= ( (3-4)/3 ; (-1+6)/3 ) 1.67
Answer:
<h2>8h 35min</h2>
Step-by-step explanation:

I bet the ODE is supposed to read

Then if
, we have
and
, and substituting these into the ODE gives

Solving for <em>r</em>, we find

so that
and
are two fundamental solutions to the ODE. Thus the general solution is

Given that
and
, we get

So the particular solution is

Answer:
Option C
Step-by-step explanation:
Zeros of a function are also called as x-intercepts of a function, which means where the graph/function intersects the x-axis.
In the image we see the graph intersects the x-axis at three points
x=0 , x=2 , x=4 so our answer is option C
