Answer:Paul should sell 3 paintings per hour to recover his cost.
Step-by-step explanation:
Total paintings = 32
Minimum amount to sale = 17
Paintings sold = 3
Paintings left = 17 - 3 = 14
Time left = 5 hours
Therefore, he needs to sell 14 paintings in 5 hours.
5 hours = 14 paintings
1 hour =
Rounding off to nearest whole number;
2.8 paintings = 3 paintings
Answer:
0, π, 7π/6, 11π/6 on the interval 0 ≤ ø <2π.
Step-by-step explanation:
sinø + 1 = cos2ø
Use the identity cos 2o = 1 - 2 sin^2 o:
sin o + 1 = 1 - 2 sin^2 o
2sin^2 o + sin o + 1 - 1 = 0
2 sin^2 o + sin o = 0
sin o (2 sin 0 + 1) = 0
Therefore sin o = 0 or sin o = -1/2.
For sin o = 0 , o = 0, π radians.
For sin o = - 1/2, o = 7π/6, 11π/6 radians.
A) y = 40x + 45. B) set x equal to 3 and solve for y. C) set 265 for y and solve for x.
