Answer:
450 x (1 + 0.5) ^ X = Phone subscribers
Step-by-step explanation:
Since a telecommunications company in a small town had 450 phone subscribers before they introduced a plan for newly joining members, and the company recorded an approximate 50% increase each month in the number of new phone subscribers, where they had one new subscriber at the start of the plan, to determine the number of phone subscribers x months after the plan was launched, the following function must be considered and solved:
450 x (1 + 0.5) ^ X = Phone subscribers
So, for example, in 3 months, the number of subscribers would be the following:
450 x (1 + 0.5) ^ 3 = 1,518.75
Thus, in 3 months, the company would have 1,518 subscribers.
-1 ≤ n + 2 ≤ 6
-2 - 2 + -3
-3 n/ 0
Answer = -3 , 4 Answer = C
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
() + () + ()
() + () + ()
() + () + ()
(8) + (2) + ()
10 +
10.5

Answer:
A
Step-by-step explanation:
because this shapes angle would be out of 360 so you do 360-83-85-69=123 is the answer you get.
hope it make sense:)
