m^2 + 9 = 0
m = ± 3i
yH = C1 cos 3t + C2 sin 3t
yP = C3 t sin 3t + C4 t cos 3t

Since the amount of money earned is based of of the amount of pies he sells...
y = 14x
Hope this helps!
Answer: 54
-------------------------------------------------------------------
Explanation:
The first ratio is 1:6. The jump from 1 to 6 has us multiplying the 1 by 6 to get 6.
1*6 = 6
So we follow the same rule of "multiply by 6" to go from 9 to 54 (9*6 = 54)
Or you can use a proportion to get
1/6 = 9/x
1*x = 6*9 ... cross multiply
x = 54
and we get the same answer
37=a+5d
114=a+16d
_________
114-37=16d-5d
77=11d
7=d
_________
37=a+5×7
37-35=a
2=a
________
a23=a+(23-1)×d
a23=2+(23-1)×7
a23=156
