Sin⁻¹ √2 = 1/√2 = 1(√2) / (√2)(√2) = √2/2
Answer:
d. 20+10+5+2.5+...
Step-by-step explanation:
No geometric series with a common ratio of magnitude greater than 1 will have a finite sum. Nor will any arithmetic series.
Those descriptions exclude answer choices a, b, c. Choice d is a geometric series with a common ratio of 1/2, so will have a finite sum. (It is 40.)
She used the associative property which should only be used with positive numbers (sorry if it isn't the answer you're looking for)
