Answer:
12
Step-by-step explanation:
12 divided by 3 is 4 and 4 times 3 is 12

has characteristic equation

with roots at
. Then the characteristic solution is

For the particular solution, consider the ansatz
, whose first and second derivatives vanish. Substitute
and its derivatives into the equation:

Then the general solution to the equation is

With
, we have

and with
,

Then the particular solution to the equation is

The answer is X^2 - 25 click on the box for more details or explain.
Answer:
Step-by-step explanation:
Given that:
The modeled equation y = 0.2x² - 0.4x - 0.6
To find x- intercepts
y = 0.2x² - 0.4x - 0.6
y = 0.2(x² - 2x - 3)
y = 0.2(x - 3)(x + 1)
Suppose the upward parabola cuts x axis at x = 3 and x = - 1
Then, the length of the intercepts will be = 3 -(-1)
=4
We can say that the trees will be 4 unit apart.
To find y-intercepts;
y = 0.2(0)² - 0.4(0) -0.6
y = -0.6 meters
Answer:
18/(-3)=-6 . (-18)/(-3)=6 . (-15)(-2)=30. 15(2)=30. 12(-4)=-48
Step-by-step explanation:
18 divided by -3 is -is -6. -18 divided by -3 is 6. -15 times -2 is 30 . 15 times 2 is 30. 12 times -4 is -48 .
