Answer:
C. 20.10
Step-by-step explanation:
V=4/3r^3
If x < - 2 and x ∈ { - 5, - 2.6, - 2, - 0.8, 1, 1.5 }
- 5 < - 2 and - 2.6 < - 2
The solution set is:
A ) { - 5 , - 2.6 }
2x + 3x + 140 = 360 (being complete turn angle)
5x + 140 = 360
5x = 360-140
5x = 220
x = 44
now 2x = 2 × 44 = 88
3x = 3 × 44 = 132
Answer:
A does not have any proportional relationship.
Step-by-step explanation:
All of the other tables have obvious relationships, leaving A to be the answer.
Answer:cot t = 1.875
but sin²t + cos²t = 1 ⇔ cos²t = 1 - sin²t
⇔cos t = 
but t is a quadrant III angle => cos t = 
=> cot t =
