Answer:
(-3,2)
Step-by-step explanation:
From the number line graph we can see that there is a open circle at -3
and an open circle at 2.
The shaded part lies between -3 and 2
So we can write inequality form as -3<x<2.
Interval form
If we have open circle then we use parenthesis when we write it in interval notation. we have open circle at -3 and 2
So interval notation is (-3,2)
??? What is the rest of the question?
The answer is C most likey
An = a1 * r^(n-1)
-405 = -5*3^(n-1)
3^(n-1) = 81
3^4 = 81 so n-1 = 3 and n = 4
Sn = S4 = -5 (1 - 3^4) / ( 1 - 3) = 400 / -2 = -200 Answer
