The following is an initial value, second-order differential equation: d 2x dt 2 1 (5x) dx dt 1 (x 1 7) sin(vt) 5 0 where dx dt (0) 5 1.5 and x(0) 5 6 Note that v 5 1. Decompose the equation into two fi rst-order differential equations. After the decomposition, solve the system from t 5 0 to 15 and plot the results.

step-by-step explanation:

2 and 1.

step-by-step explanation:

plug in each answer. 0 doesn't work, 1 does. so does 2. 4 doesn't:

0 = 1 is not true.

2 = 2 is true.

4 = 4 is true.

8 = 16 is not true.

hope this !

dont know

step-by-step explanation:

the height of the surface increases from the center out to the sides of the road.

step-by-step explanation:

as we move out we move away from the x-axis.

and as mentioned in the problem statement that height of a road increases when we move away from the center x.

hence proved that 3rd option

the height of the surface increases from the center out to the sides of the road.

is the correct option.
