Since 18 is one twentieth of the angle of a full circle, 360, the circumference is 20 times the arc distance of 15, or 300
Answer:
(b^2 + 8b - 9) - (11b^2 + 4b -7)
b^2 + 8b - 9 - 11b^2 - 4b + 7
- 10b^2 + 12b -16
Step-by-step explanation:
11pi/12
Note:
2pi = 360°
(11pi/12)(360°/2pi)
330°
I count 5. There could be more. Sorry. Don't have scratch paper at the moment.
Answer:
(0,-9) You have to substitute 0 for x and solve for y
