The answer would be
f(1) = 2 f(n) = f(n-1) + 3
The x-intercepts are -6 (put the radical over the 6) and 6 (put the radical over it) or if you need the simplified version they are -2.44 and 2.44
To use the equation we need a1 and d(the common difference).
We have a1 = 57, we need to find d.
93-84 = 9; 84-75=9; 75-66=9; 66-57=9
d = 9
a350 = 57 + (350-1)(9)
a350 = 57 + (349)(9)
a350 = 57 + 3141
a350 = 3198
Are you looking for the length from E to F?
Answer:
If its asking you to round to the nearest tenths place then its 0.2
remember that if the number you're using to round is 5 or higher you add 1. If its 4 or lower it stays the same
