Part A:
The differential equation is:
y '= 0.08y
The initial condition is:
P (0) = 500 Part B:
The formula for this case is:
P (t) = 500exp (0.08 * t) Part C:
After five days we have to evaluate t = 5 in the equation.
We have then:
P (5) = 500 * exp (0.08 * 5)
P (5) = 745.9123488
Rounding:
P (5) = 746
The GCF would be 9.
You would first find the prime 36=2*2*3*3
Then do the same with 63. 63=3*3*7
So to find the GCF you would multiply the prime factors that are the same with 36 and 63. So you would multiply 3*3 which would give you 9.
GCF=9
