Answer:
3/8 x 5/8 x 7/8=105/512.
Step-by-step explanation:
No because they still need because 121
Because 5000-4870=121
2,387+2,492=4879
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:
The answer is the last option, D.
Step-by-step explanation:
A function with one solution can be added and have a variable and a constant leftover. The variables in the other three options cancel each other out, so none of them have one solution. The first and third equations have no solutions, and the second has infinitely many solutions. The fourth option has only one variable cancel out and still has a constant on the other side of the equation. The fourth option is correct.
If in a fraction, the numerator or the denominator or both are fractions, then it is called a complex fraction.
Example 1:

Here, since the numerator is a fraction, it is a complex fraction.
Example 2:

Here, since the numerator and the denominator are fractions, it is a complex fraction.
