Answer:
<em><u>17: 480</u></em>
(We first arrange all of the candidates except b in a line. This can be done in 5! ways. We now add b to the line. Since we now want to count the arrangements where b is positioned next to a, there are two possibilities for the position of b. (Either left of a or right of a).
There are thus 2⋅5! ways of arranging the candidates so that a and b are next to each other, and hence 6!−2⋅5!=4⋅5!=480 ways of arranging the candidates so that a and b are not next to each other)

What is the logarithmic Expression?
A logarithmic expression is an function that involves the logarithm of an expression containing a variable. To solve exponential equations, first see whether you can write both sides of the equation as powers of the same number.
Here = 
= 
= 
= 
= 
= 
= 
= 1 + 0.5283
l ≈ 1.53
The approximate value of is 1.52832 or 1.53.

The area given is 380.13
·The equation to find are is pi(r²)=a
·The equation to find the diameter of a circle using the area is a/pi=D
Knowing this we just plug everything in.
·380.13/3.14=D
Now knowing this we solve
380.13/3.14=120.99
