In the sequence, we are given with -2, 8, -32...This is a geometric type of sequence with a geometric ratio of 4. a1 is equal to -2 and r is equal to 4The expression is
a n = a1 * r ^ (n-1) where n is an integer ora n = a1 * (-4) ^ (n-1)we can check or verify this using the given
Answer:
Step-by-step explanation:
Answer:
I believe the answer is B, and the other answer is D.
³√250 = ³√2 ³√125 = 5 ³√2
<span>we need to show that ³√2 is irrational</span>
Answer: B
<u>Step-by-step explanation:</u>
-10x² + 12x - 9 = 0
a=-10, b=12, c=-9
