Answer:
Additive Identity I think, I'm not sure
Step-by-step explanation:
Tell me in the comments if I'm wrong.
The independent would be the base amount (0.25 in this case) The dependent would be :
the sum of the minutes x 0.25 or the entire phone bill

Answer: 7.20</h3>
Work Shown:
18% = 18/100 = 0.18
18% of 40 = 0.18*40 = 7.20
First way
arcsin(1/4) means that 1/4 sin of the angle.
sin(α)=1/4
sin²α+cos²α=1
(1/4)²+cos²α=1
cos²α=1-1/16 =15/16
cosα=+/-(√15)/4
<span>Second way
</span>
sin(α)=1/4 =opposite leg/hipotenuse
cos(α)=adjacent leg/hypothenuse
adjacent leg =√(hypotenuse²- Opposite²)=√(16-1)=√15
cosα=+/-√15/4
For one value of sinα, possible 2 values of cosα.
