Answer:
(0,3) and (5,0)
Step-by-step explanation:
Answer:
sin A = 13/85
Step-by-step explanation:
Opposite Angle A is side BC, of length 13. The length of the hypotenuse is 85. The sine function is defined as the ratio opp/hyp. In this problem that ratio is
opp
------ = sin A = 13/85
hyp
We use the inverse sine function arcsin x to determine Angle A:
A = arcsin 13/85 = 8.8 degrees
Answer:
- 320 +0.05s ≥ 600
- sales ≥ $5600
Step-by-step explanation:
For sales of 's', Alan's earnings will be ...
320 +0.05s
He wants that to be at least 600, so the inequality is ...
320 +0.05s ≥ 600
__
Its solution is found by subtracting 320 and dividing by 0.05.
0.05s ≥ 280
s ≥ 5600
Alan's weekly sales must be at least $5600 for his earnings to cover his expenses.
