Answer:
Step-by-step explanation:
I think you meant y = -x^n, where ^ denotes exponentiation.
If n is odd, the graph begins in Quadrant II and decreases through the origin into Quadrant IV. This is true of -x, -x^3, -x^5, and so on.
Hmmm... a geometric sequence MUST have a fixed common ratio. If it is changing, then the sequence you are looking at might not be a geometric sequence at all. We'd need to see an example to be sure.
The answer is 142°
Explanation:
angle 1 and angle 2 form are supplementary.
m∠1 + m∠2 = 180°
38° + m∠2 = 180°
m∠2 = 180° - 38°
m∠2 = 142°
Hope it helps!
