Answer is a, 57.49.
17.42-12.60-9.62= $-4.80+62.29=57.49
Answer:
n = π/6, π/4, 3π/4, 5π/6
Step-by-step explanation:
sin(3n) − sin n = cos(2n)
Use double and triple angle formulas:
(3 sin n − 4 sin³ n) − sin n = 1 − 2 sin² n
2 sin n − 4 sin³ n = 1 − 2 sin² n
4 sin³ n − 2 sin² n − 2 sin n + 1 = 0
Factor by grouping:
2 sin² n (2 sin n − 1) − (2 sin n − 1) = 0
(2 sin² n − 1) (2 sin n − 1) = 0
Solve:
2 sin² n − 1 = 0
2 sin² n = 1
sin² n = 1/2
sin n = √2/2
n = π/4, 3π/4
2 sin n − 1 = 0
2 sin n = 1
sin n = 1/2
n = π/6, 5π/6
At most 12 peppers can be bought with $18
Step-by-step explanation:
Given
Total amount for peppers = $18
Cost per pepper = $1.50
Let p be the number of peppers that can be bought from $18 at $1.50 per pepper
So,
Dividing both sides by 1.50
Hence,
At most 12 peppers can be bought with $18
