First: the homogeneous solutions: the characteristic equation is4r^2 - 4r - 3 = 0which has roots r = 3/2, -1/2 hence the homogeneous solution isy = c1.exp(-x/2) + c2.exp(3x/2)
next you need the general form for the guess for yp and that isyp = A1cos(2x) + A2sin(2x)
Now substitute that into the equation and solve for A1, A2.
Answer:
A) (4,1) C) (12,3) D) (20,5)
Step-by-step explanation:
Required
Which has a constant of proportionality of 1/4
To solve this, we make use of:

Where k is the constant of proportionality.
Solve for x

Let the middle point be M.
MDC is a isometric triangle.
∠MDC = MCD = 25°
∠DBC = 180-25-25-35 = 95°
1) 4
2) 2
Pretty sure thats right
Answer:
10+ (4 23 + 7) - 19
I don't know if the 4 is supposed to be multiple or subtract or to add but If it is add
