Answer:
1) Angle AOC + Angle COB = Angle AOB
Angle AOC = X
Angle COB = Y
putting in equation, we get
X + Y = AOB
2) Angle X + Y = AOB (proved above)
AOB = 90° ( given)
Angle X + Angle y = 90°
Angle X is the complement of Y
The equation would be y = 7.50x - 8.
The graph would be an increasing straight line.
Answer:
10
Step-by-step explanation:
200-65= 135
135/13.5=10
Volume of a sphere: V=(4/3)πr³
V1=(4/3)π10³
V2=(4/3)π5³
difference: (4/3)π10³-(4/3)π5³=(4/3)π875=3665
the answer is B.<span />
