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.
Answer:
7.5 units squared
Step-by-step explanation:
Equation for solving the area is A = 1/2h(b1 + b2).
The bases here have a length of 4 and 1, so we add them together. The height is 3, so our equation is 1/2 * 3(5) = 7.5
Answer:
$0.49
Step-by-step explanation:
Using the conversion
1 pound = 16 ounces , then
6 pounds = 6 × 16 = 96 ounces, thus
cost of 1 ounce = 
= $0.49
8/30
= (8/2) / (30/2)
= 4/15
8/30 in its simplest form is 4/15~
