Answer:
- arc BC: 8.55 cm
- chord BC: 8.03 cm
Step-by-step explanation:
The length of an arc that subtends central angle α will be ...
s = rα . . . . where α is in radians
The central angle BOC is twice the measure of angle QBC, so is 70°, or 7π/18 radians. So, the length of arc BC is ...
s = (7 cm)(7π/18) ≈ 8.55 cm . . . arc BC
__
For central angle α and radius r, the chord subtending the arc is ...
c = 2r·sin(α/2)
c = 2(7 cm)sin(35°) ≈ 8.03 cm . . . . chord AB
I'm not sure what the question is asking. But it can be rewritten as n≥50 which shows the solved equality
Answer:
The answer to your question is below
Step-by-step explanation:
To decide if a point is a solution to the inequality, this point when plotted must be in the shaded area.
(0, 0) It is a solution of the inequality
(4, -1) It is not part of the inequality
(-1, 4) It is a solution of the inequality
(0, -2) It is not a solution to the inequality
(-2, 0) It is a solution to the inequality
(-4, 0) It is a solution to the inequality
