Answer:
I think it is maybe 19% but Idk.
Because 14 would seem to low without work and the other are pretty high so im just guessing.
Answer:
The answer is 102 miles
Step-by-step explanation:
To get this, find either Hot Springs or Sturgis on the left hand column. Once you have found the row labelled with it, follow it over until the column with the header of the other one. No matter which one you start with, you will get the same answer.
Answer:
=ei x
Step-by-step explanation:
Consider the function on the right hand side (RHS)
f(x) = cos( x ) + i sin( x )
Differentiate this function
f ' (x) = -sin( x ) + i cos( x) = i f(x)
So, this function has the property that its derivative is i times the original function.
What other type of function has this property?
A function g(x) will have this property if
dg / dx = i g
This is a differential equation that can be solved with seperation of variables
(1/g) dg = i dx
integral (1/g) dg = integral i dx
ln| g | = i x + C
| g | = ei x + C = eC ei x
| g | = C2 ei x
g = C3 ei x
So we need to determine what value (if any) of the constant C3 makes g(x) = f(x).
If we set x=0 and evaluate f(x) and g(x), we get
f(x) = cos( 0 ) + i sin( 0 ) = 1
g(x) = C3 ei 0 = C3
These functions are equal when C3 = 1.
Therefore,
cos( x ) + i sin( x ) = ei x
