Prove the superposition principle for nonhomogeneous equations. Suppose that y1 is a solution to Ly1 = f(x) and y2 is a solution to Ly2 = g(x) (same linear operator L). Show that y = y1 + y2 solves Ly = f(x) + g(x). Differential Equation.

Step-by-step explanation:

Given Data

Suppose That is a solution of L = F(x)

and is a solution  of = g(x)

L is liner operator

∴ = L +

L(y) = F(x) + g(x)

is the solution to  L(y) = F(x) + g(x)

E.g the liner operator be L =

 = f(x)

= g(x)

= + = f(x) + g(x)

2. angles qrt and qst both measures 156 degrees.

step-by-step explanation:  

we have been given a diagram of a circle and we are told that measure of arc qvt is 156 degrees.  

we can see from our given diagram that angle qrt and angle qst subtends to arc qvt.

since we know that angles subtended by the same arc at the circumference are always equal.

by angle subtended by same arc theorem, measure of angle qrt and angle qst will be equal to the measure of arc qvt.

therefore, angles qrt and qst both measures 156 degrees and 2nd statement is the correct choice.
