Use the method of undetermined coefficients to solve the differential equation.
+ y = 9x + cos 2x; 
= 0 and y = 9? when x = ?
A. y = -9 sin x - 
cos x + 9x - 
cos 2x
B. y = 9 sin x + 
cos x + 9x - 
cos 2x
C. y = 9 sin x - 
cos x + 9x - 
sin 2x
D. y = 9 sin x - 
cos x + 9x - 
cos 2x
Find all the first order partial derivatives for the following function.f(x, y, z) = x2y + y2z + xz2
A. 
= 2xy; 
= x2 + 2yz; 
= y2 + 2xz
B. 
= 2xy + z2; 
= x2 + yz; 
= y2 + xz
C. 
= 2y + z2; 
= x2 + 2z; 
= y2 + 2x
D. 
= 2xy + z2; 
= x2 + 2yz; 
= y2 + 2xz
Use similar triangles and the fact that corresponding sides are proportional to find the length of the side marked with an x.
A. 9 m B. 4 m C. 6 m D. 3 m
