400+0.1s
400 represents how much she earns per week
0.1 represents the percentage
s represents her weekly sales
0.1s represents how much of the weekly sales she gets to have.(I'm not sure if I worded the last one correctly.)
Yes, ode45 can be used for higher-order differential equations. You need to convert the higher order equation to a system of first-order equations, then use ode45 on that system.
For example, if you have
... u'' + a·u' + b·u = f
you can define u1 = u, u2 = u' and now you have the system
... (u2)' + a·u2 + b·u1 = f
... (u1)' = u2
Rearranging, this is
... (u1)' = u2
... (u2)' = f - a·u2 - b·u1
ode45 is used to solve each of these. Now, you have a vector (u1, u2) instead of a scalar variable (u). A web search regarding using ode45 on higher-order differential equations can provide additional illumination, including specific examples.
Answer:
3^6-2 = 727
3^6-1 = 728
3^6-0 = 729
3^6+1 = 730
3^6+2 = 731
Step-by-step explanation:
The answer is x=6, have a good day!
Uh sure if you give me the problem I could help
