Answer:
arc AB = 60°
Step-by-step explanation:
The diameter splits the circle into two semi circles.
in the semicircle above the diameter, you can do 180° - 120° = 60°
so arc AB = 60°
( I'm sorry; I'm not sure how to get the answer in terms of pi. )
Answer:
Step-by-step explanation:
The difference in fixed cost is $9; the difference in per-mile cost is $0.02. The difference in per-mile cost will equal the difference in fixed cost for a distance of ...
$9.00/($0.02/mi) = 450 mi
At that distance, the rental cost is ...
$50 +450×$0.15 = $50 +67.50 = $117.50
Both plans will cost $117.50 for 450 miles of driving.
-x² - x + 6
First thing I would do is distribute out that negative. Your new problem is:
- (x² + x - 6)
Now, factor the inside. We need to find products of - 6 that when added together have a sum of positive 1. They are 3 and - 2.
- (x² + 3x - 2x - 6)
Group together and find your factors. I'm going to short cut and go right to them for the sake of space and time.
- (x + 3)(x - 2)
