Essentially this is asking you to sum the first three values of the geometric series that starts with i being 1 and has the rule of (
).
Since we must sum the first <em>three </em>geometric values we need to see what the value of i will be for the first three. The sigma notation shows us that the first i will be equal to 1. This means the second i is 2 and the third i is 3.
Knowing this you can plug in the corresponding i values into () and sum it all together

to get the percentage you put the number of occupied seats over total number of seats and multiply it by 100 over 1
Answer:
32y
Step-by-step explanation:
0xy=0
If you change x or y on any number, you will get 0: 5*0=0, 100*0=0
So, 0+32y = 32 y
The answer could be 67, 68, or 69.

Answer:
[-2, ∞]
Step-by-step explanation:
15 - √(x+2)
domain is any value as long as (x+2) is not-negative, since √ of a negative number has no Real solution.
x+2 ≥ 0 ⇒ x ≥ -2
