Estimation. 31 Exact Answer 30.702
Step-by-step explanation:
I rounded 2.6 to 2 and 22.652 to 23 and rounded 5.45 to 5 and that is how I got my estimation and then I added them all up to get the exact number
QT = RS
30 = 4x + 10
20 = 4x
x = 5
answer
x = 5 It's B. second choice
I think it is .8 i could be wrong i’m not sure
Answer: C) 127, 152.4, 182.88, 219.456,...
Step-by-step explanation:
You can only find the sum of an infinite geometric sequence if it converges.
One criterion to see if the series converges is if:
aₙ < aₙ₋₁
This means that, as n increases, the value of the terms decreases.
This means that as n tends to infinity, aₙ tends to zero.
Then we only can find the sum of those series where the terms are decreasing.
in A, B and D the terms are decreasing, then we can find the sum of those 3 series.
Now in the case of C, the terms are increasing, then we can not find the sum of that series.
